Detailed Description
The scar poking device for the alumina settling tank shown in the drawing is arranged on the alumina settling tank 17 (the concrete installation position is at the bottom of the settling tank and is overlapped on a knife gate valve 16 (the knife gate valve is arranged at the discharge hole part of the settling tank).
In the scar poking device, a valve body is fixed on a knife gate valve, and a valve rod is coaxially arranged with the knife gate valve (the axis of the valve rod is coaxially arranged with the axis of a valve shell of the knife gate valve); the valve body comprises a motor base 2-1, a bearing seat 7-1, a connecting disc 9, a valve cover 13 and a base 15 which are connected through fasteners; wherein the connecting disc 9 and the valve cover 13 are connected into a whole through a plurality of upright posts 12 (preferably 3 upright posts) which are parallel to each other; the valve rod can be axially movably positioned on the valve body, the bottom end of the valve rod is provided with a valve cone 14, and the valve cone is made of metal materials into a water drop shape with a sharp top end so as to be beneficial to propping and poking the alumina deposition layer; the hollow shaft 3 is sleeved on the valve rod 11 in a penetrating way, and the motor 2 arranged at the top end of the valve body drives the hollow shaft through a transmission assembly (preferably a gear pair); the end face clutch 4 is positioned in the bearing seat through a bearing 7, also sleeved on the valve rod and meshed by the hollow shaft; the end face clutch comprises a plurality of meshing teeth 3-1 which are manufactured on the lower end face of the hollow shaft and a plurality of meshing teeth 4-1 which are manufactured on the upper end face of the end face clutch; the meshing teeth are meshed with each other to form the end face clutch. The complete set of the motor driving the hollow shaft through the transmission assembly can be directly purchased externally.
The axial slider is arranged between the end face clutch and the valve rod; in the axial slider, the engagement ring 5 is enclosed on the outer circumferential surface of the valve rod and is fixed (screwed) with the end surface clutch; the inner circumferential surface of the engagement ring is uniformly provided with a plurality of straight grooves 5-1 parallel to the axis, the outer circumferential surface of the valve rod is uniformly provided with a plurality of straight grooves 11-1 (4 straight grooves and 4 straight grooves are shown in fig. 5; the number can be determined according to the need), and a plurality of steel balls 6 are simultaneously engaged with the straight grooves and the straight grooves so as to enable the engagement ring and the valve rod to synchronously rotate. The number of the straight grooves is the same as that of the straight grooves, the straight grooves are arranged in a one-to-one correspondence manner, and a plurality of steel balls (a plurality of steel balls are arranged in a straight line) which are arranged in a straight line are embedded in each straight groove and the corresponding straight groove.
As can also be seen from fig. 3: the axial sliding device is divided into an upper section and a lower section, and after all the steel balls are installed in place, the upper section and the lower section of the axial sliding device are oppositely clamped between the two thrust bearings.
The valve rod nut 8 is fixed on the bearing seat and is in threaded fit with the valve rod so as to enable the valve rod to axially slide; the motion track of the valve cone passes through the cavity in the valve body of the knife gate valve and extends into the settling tank (see figure 2), and can push against the alumina deposition scab layer at the bottom of the impact settling tank when in use so as to keep the discharge pipeline of the settling tank smooth.
Preferably, the cross section contour lines of the straight groove and the straight line groove are arc-shaped which is matched with the steel balls, so that friction resistance matched with the steel balls in a sliding way is reduced.
Furthermore, the invention is also provided with a hand wheel 1, the motor output shaft is driven by the rotating hand wheel through an overrunning clutch (the motor output shaft has no driving force to the rotating hand wheel, and the rotating speed of the motor output shaft can exceed the rotating speed of the rotating hand wheel); this is prior art.
There is also an indicator disc 10 showing the distance the valve cone moves.
