Description

Technical Field

[0001] The utility model belongs to the technical field of hydrometallurgy, and particularly relates to an anti-blocking device for the liquid inlet of a pump body. Background Technique

[0002] The pump body provides a basic structure for installing and fixing each component of the pump. It is like a solid shell that wraps key components such as the impeller, shaft, and sealing device, ensuring that they maintain a relatively stable positional relationship during operation. For example, in a centrifugal pump, the pump body is usually in a volute shape, providing a specific space for the rotation of the impeller, enabling the impeller to work efficiently therein.

[0003] During the operation of the existing pumps in the zinc solution preparation workshop, the pumps are often blocked due to crystallization, debris, etc. In most cases, it leads to damage to the pump impeller, pump casing, and even the motor, and at the same time has a great impact on the output of qualified liquid, resulting in serious economic losses. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for filtering and preventing blockage at the pump inlet. By setting an anti-blocking mechanism, it solves the problems that during the operation of the existing pumps in the zinc solution preparation workshop, the pumps are often blocked due to crystallization, debris, etc., which in most cases leads to damage to the pump impeller, pump casing, and even the motor, and at the same time has a great impact on the output of qualified liquid, resulting in serious economic losses.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is an anti-blocking device for the liquid inlet of a pump body, including an anti-blocking pipe for the liquid inlet, and an anti-blocking mechanism is arranged on the anti-blocking pipe for the liquid inlet;

[0007] An anti-blocking cylinder is rotatably connected to the inner wall of the anti-blocking pipe for the liquid inlet. The shape of the anti-blocking cylinder is conical. A rotating groove is opened on the inner wall of the anti-blocking pipe for the liquid inlet. A clamping ring is fixedly connected to the outer wall of the anti-blocking cylinder, and the outer wall of the clamping ring rotates and extends into the rotating groove.

[0008] Furthermore, the anti-blocking mechanism includes a cross-shaped support frame one fixedly connected to the inner wall of the anti-blocking pipe for the liquid inlet. A support shaft rotatably penetrates through the middle axis of the cross-shaped support frame one, and the left side of the support shaft is fixedly connected to the anti-blocking cylinder.

[0009] Furthermore, a plurality of holes are opened on the anti-blocking cylinder, and all the plurality of holes penetrate through the anti-blocking cylinder.

[0010] Furthermore, filter meshes are fixedly connected to the inner walls of all the plurality of holes, and a cross-shaped support frame two is fixedly connected to the inner wall of the anti-blocking pipe for the liquid inlet.

[0011] Further, a rotating shaft penetrates through the central axis of the second cross-shaped support frame, and the right side of the rotating shaft is fixedly connected to the anti-blocking cylinder.

[0012] Further, a rotating wheel is fixedly connected to the left extension part of the rotating shaft, and several rubber tubes are fixedly connected to the inner wall of the anti-blocking cylinder.

[0013] The utility model has the following beneficial effects:

[0014] By setting up the anti-blocking mechanism, first, a conical anti-blocking cylinder is installed inside the anti-blocking device. Then, a rotating shaft is installed in the middle of the anti-blocking cylinder, and a rotating wheel is installed on the rotating shaft facing the inlet. At the same time, several round holes are opened on the outer surface of the anti-blocking cylinder. When the liquid enters the anti-blocking pipe at the inlet of the liquid inlet through the pump inlet, the liquid will impact the rotating wheel, causing the rotating wheel to drive the anti-blocking cylinder to rotate through the rotating shaft. Then, multiple rubber tubes are installed inside the anti-blocking cylinder, and the rotating shaft drives the rubber tubes to rotate when rotating. Since the surface of the rubber tube will fit against the inner wall of the anti-blocking cylinder when the rubber tube rotates, it can produce a rubbing effect on the inside of the anti-blocking cylinder. At the same time, it can also stir the liquid entering the anti-blocking cylinder. When the liquid enters the anti-blocking cylinder, the centrifugal force generated by the rotation of the anti-blocking cylinder will cause the liquid to be thrown to the surroundings and discharged through the holes on the anti-blocking cylinder. Then, a filter screen can be installed on the holes. At the same time, when the rubber tube rotates, it can rub the impurities on the inner surface of the filter screen to make them fall off the filter screen. At the same time, when the rubber tube rotates, it can also stir the liquid inside the anti-blocking cylinder, accelerating the outward discharge of the liquid, and cleaning the impurities on the filter screen during rotation, reducing the situation of blocking the pump body, improving the anti-blocking effect of the anti-blocking device, using the filtering device to preventively filter crystals and sundries, avoiding losses caused by damage to the impeller and pump shell of the pump body, reducing costs, reducing production impact, improving the operation rate and output, and indirectly increasing benefits and profits.

[0015] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Please refer to Figures 1-5As shown in the figure, the utility model relates to an anti-blocking device for the liquid inlet of a pump body, which includes an anti-blocking pipe 1 for the liquid inlet. An anti-blocking mechanism 2 is arranged on the anti-blocking pipe 1 for the liquid inlet. An anti-blocking cylinder 101 is rotatably connected to the inner wall of the anti-blocking pipe 1 for the liquid inlet. The shape of the anti-blocking cylinder 101 is conical. A rotating groove 102 is formed on the inner wall of the anti-blocking pipe 1 for the liquid inlet. A clamping ring 103 is fixedly connected to the outer wall of the anti-blocking cylinder 101. The outer wall of the clamping ring 103 extends rotatably into the rotating groove 102. The anti-blocking mechanism 2 includes a cross-shaped support frame one 201 fixedly connected to the inner wall of the anti-blocking pipe 1 for the liquid inlet. A support shaft 202 rotatably penetrates through the central axis of the cross-shaped support frame one 201. The left side of the support shaft 202 is fixedly connected to the anti-blocking cylinder 101. A plurality of holes 203 are formed in the anti-blocking cylinder 101. The plurality of holes 203 all penetrate through the anti-blocking cylinder 101. Filter meshes 204 are fixedly connected to the inner walls of the plurality of holes 203. A cross-shaped support frame two 205 is fixedly connected to the inner wall of the anti-blocking pipe 1 for the liquid inlet. A rotating shaft 206 rotatably penetrates through the central axis of the cross-shaped support frame two 205. The right side of the rotating shaft 206 is fixedly connected to the anti-blocking cylinder 101. A runner 207 is fixedly connected to the left extending part of the rotating shaft 206. A plurality of rubber tubes 208 are fixedly connected to the inner wall of the anti-blocking cylinder 101. By arranging the anti-blocking mechanism, when the liquid enters the interior of the anti-blocking cylinder 101, the centrifugal force generated when the anti-blocking cylinder 101 rotates will cause the liquid to be thrown to the surroundings and discharged outward through the holes 203 in the anti-blocking cylinder 101. Then, a filter net 204 can be installed on the holes 203. At the same time, when the rubber tubes 208 rotate, the impurities on the inner surface of the filter net 204 can be rubbed to make them fall off from the filter net 204. At the same time, when the rubber tubes 208 rotate, the liquid inside the anti-blocking cylinder 101 can also be stirred to accelerate the outward discharge of the liquid, and during the rotation, the impurities on the filter net 204 can be cleaned in this way, reducing the situation of blocking the pump body and improving the anti-blocking effect of the anti-blocking device.

[0026] A specific application of this embodiment is as follows: First, a conical anti-blocking cylinder 101 is installed inside the anti-blocking device. Then, a rotating shaft 206 is installed in the middle of the anti-blocking cylinder 101, and a runner 207 is installed on the rotating shaft 206 facing the inlet. At the same time, a number of round holes are opened on the outer surface of the anti-blocking cylinder 101. When the liquid enters the anti-blocking pipe 1 at the inlet of the pump, the liquid will impact the runner 207, causing the runner 207 to drive the anti-blocking cylinder 101 to rotate through the rotating shaft 206. Then, a plurality of rubber hoses 208 are installed inside the anti-blocking cylinder 101, and the rotating shaft 206 drives the rubber hoses 208 to rotate when rotating. Since the surface of the rubber hose 208 will fit against the inner wall of the anti-blocking cylinder 101 when the rubber hose 208 rotates, it can produce a rubbing effect on the inside of the anti-blocking cylinder 101, and at the same time, it can also stir the liquid entering the anti-blocking cylinder 101. When the liquid enters the anti-blocking cylinder 101, the centrifugal force generated when the anti-blocking cylinder 101 rotates will cause the liquid to be thrown out in all directions and discharged outward through the holes 203 on the anti-blocking cylinder 101. Then, a filter screen 204 can be installed on the holes 203. At the same time, when the rubber hose 208 rotates, it can rub the impurities on the inner surface of the filter screen 204 to make them fall off the filter screen 204. At the same time, when the rubber hose 208 rotates, it can also stir the liquid inside the anti-blocking cylinder 101, accelerating the outward discharge of the liquid, and when rotating, it can clean the impurities on the filter screen 204 in this way, reducing the situation of blocking the pump body and improving the anti-blocking effect of the anti-blocking device.
