Description

Technical Field

[0001] The utility model relates to the technical field of anti-blocking devices, and particularly relates to an anti-blocking device for a sludge pump. Background Art

[0002] In coal-fired power plants, since a large amount of dust is generated when the coal conveying system transports materials, manual water flushing is required for cleaning. The water after flushing is mixed with impurities such as solid dust to form sludge water.

[0003] The flushed sludge water is pumped to the coal-containing wastewater room by a sewage pump, and then the sludge pump in the coal-containing wastewater room pumps the coal water containing sludge to a flocculator for separation and re-filtering to use the wastewater. Due to a large amount of sludge accumulation at the inlet of the sludge pump, the sludge pump often gets blocked, cannot operate normally, and even causes the pump to burn out.

[0004] In the prior art, the blockage of the sludge pump can be alleviated by means of water flow flushing, such as a sludge pump anti-blocking flushing device with the publication number of CN214036224U.

[0005] During the flushing process, the water flow converges from all directions to the central position, and the forces of two water flows in opposite directions will cancel each other out, resulting in a weakened water flow impact force and affecting the final impact effect. Content of the Utility Model

[0006] The purpose of the utility model is to provide an anti-blocking device for a sludge pump. Through the isolation effect of the central rod, the water flows spraying from all directions will not converge, and the forces of the water flows in all directions will not cancel each other out, so that the impact force of the water flow can be fully utilized, the pulverizing effect on the sludge can be improved, and thus the anti-blocking effect is improved.

[0007] To achieve the above purpose, the utility model provides the following technical solution: an anti-blocking device for a sludge pump, including an annular channel. The outer end of the annular channel is fixedly provided with a water inlet pipe, and the high-pressure water flow is input into the annular channel through the water inlet pipe.

[0009] Further, the spraying component includes a U-shaped pipe fixedly arranged at the top of the annular channel. The outer end of the U-shaped pipe is sleeved with an adjusting pipe through a sealed bearing, and a fastening bolt is arranged at the outer end of the adjusting pipe through a thread.

[0010] A plurality of communication holes located inside the adjusting pipe are provided at the outer end of the U-shaped pipe, and a nozzle with a pressure regulating valve is fixedly provided at the outer end of the adjusting pipe.

[0011] Further, a handle is fixedly provided at the bottom end of the central rod. The central rod is rotated by the handle to adjust the position of the central rod, and a knocking assembly is provided at the top end of the central rod.

[0012] Further, an impeller shaft is provided at the top end of the central rod through a bearing. A plurality of impellers are fixedly provided at the outer end of the impeller shaft. First springs are fixedly provided at the outer ends of the impeller shafts, and a striking block is fixedly provided at one end of each first spring.

[0013] Further, mounting assemblies are provided on both sides of the annular channel. The mounting assembly includes a clamping plate for clamping at the bottom end of the inlet of the sludge pump. A fastening bolt is provided on the clamping plate by means of a thread, and an extension piece located inside the inlet of the sludge pump is fixedly provided at the outer end of the clamping plate.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0028] The present utility model provides a sludge pump anti-blocking device as shown in Figures 1-5 Figure, which includes an annular channel 1. An inlet water pipe 7 is fixedly arranged at the outer end of the annular channel 1, and the inlet water pipe 7 inputs high-pressure water flow into the annular channel 1. Ten injection assemblies 2 are arranged at the top of the annular channel 1, and the water flow is directed towards the sludge pump through the injection assemblies 2;

[0029] A sleeve 9 is arranged at the bottom of the annular channel 1. Brackets 8 connected to the annular channel 1 are fixedly arranged at both ends of the sleeve 9. A central rod 4 is arranged at the central position inside the annular channel 1. Both ends of the central rod 4 extend to the top and bottom of the annular channel 1 respectively, and the sleeve 9 is threadedly sleeved on the outer end of the central rod 4.

[0030] The annular channel 1 is installed at the inlet of the sludge pump. High-pressure water flow is input into the interior of the annular channel 1 through the water inlet pipe 7. The water flow is sprayed towards the inlet of the sludge pump through the spraying assembly 2. The sludge at the inlet of the sludge pump is broken and diluted into fine particles by the impact force of the high-pressure water flow. The fine particles can be normally sucked and discharged by the sludge pump, avoiding blockage caused by large pieces of sludge, thus ensuring the normal operation of the pump. At the same time, a central rod 4 is arranged at the central position on the inner side of the annular channel 1. Under the isolation of the central rod 4, the water flows sprayed from all directions will not converge, and the forces of the water flows in all directions will not cancel each other out, so that the impact force of the water flow can be fully utilized, improving the crushing effect on the sludge and thus improving the anti-blocking effect.

[0031] During the use process, it is necessary to adjust the direction of the water flow. As Figure 2 , 3 shown, the spraying assembly 2 includes a U-shaped pipe 201 fixedly arranged at the top end of the annular channel 1. An adjusting pipe 203 is sleeved outside the U-shaped pipe 201 through a sealing bearing. A fastening bolt is arranged at the outer end of the adjusting pipe 203 through a thread.

[0032] A plurality of communication holes 202 located inside the adjusting pipe 203 are opened at the outer end of the U-shaped pipe 201. A nozzle 204 with a pressure regulating valve is fixedly arranged at the outer end of the adjusting pipe 203.

[0033] The water flow entering the interior of the annular channel 1 enters the U-shaped pipe 201 and flows into the interior of the adjusting pipe 203 through the communication holes 202, and finally sprays out through the nozzle 204. The pressure regulating valve on the nozzle 204 can adjust the water pressure, and rotating the adjusting pipe 203 can adjust the direction of the nozzle 204, thereby adjusting the direction of the water flow. After adjustment, the position of the adjusting pipe 203 is fixed by the fastening bolt on the adjusting pipe 203.

[0034] In order to prevent sludge from adhering to the inner wall of the sludge pump, as Figure 1 , 4 , 5 shown, a handle 6 is fixedly arranged at the bottom end of the central rod 4. The central rod 4 is driven to rotate by the handle 6 to adjust the position of the central rod 4. A knocking assembly 3 is arranged at the top end of the central rod 4.

[0035] An impeller shaft 301 is arranged at the top end of the central rod 4 through a bearing. A plurality of impellers 302 are fixedly arranged at the outer end of the impeller shaft 301. First springs 303 are fixedly arranged at the outer end of the impeller shaft 301. An impact block 304 is fixedly arranged at one end of the first spring 303.

[0036] Installation assemblies 5 are arranged on both sides of the annular channel 1. The installation assembly 5 includes a clamping plate 506 used for clamping at the bottom end of the inlet of the sludge pump. A fastening bolt is arranged on the clamping plate 506 through a thread. An extension piece 507 located inside the inlet of the sludge pump is fixedly arranged at the outer end of the clamping plate 506.

[0037] The device is installed at the bottom of the inlet of the sludge pump. During installation, the clamping plates 506 of the two installation components 5 are stuck at the inlet of the sludge pump and fixed to the sludge pump through the fastening bolts on the clamping plates 506, thereby installing the device on the sludge pump. The extension pieces 507 on the clamping plates 506 are located inside the inlet of the sludge pump. The knocking component 3 at the top of the central rod 4 extends into the inlet of the sludge pump and is located between the two extension pieces 507. When the water flows into the sludge pump, the water drives the impeller 302 and the impeller shaft 301 to rotate and drives the first spring 303 and the impact block 304. During the rotation of the impact block 304, it impacts the extension piece 507, causing the entire installation component 5 to vibrate and resulting in the vibration of the sludge pump. The vibration of the sludge pump is utilized to make it difficult for the sludge to adhere to the inner wall of the sludge pump.

[0038] This device can adapt to sludge pumps of different sizes. For example, Figure 1 , 5 As shown, the installation component 5 further includes an installation arm 501 fixedly arranged at the outer end of the annular channel 1. The top of the installation arm 501 is fixedly provided with a fixed seat 502. A guide rod 504 penetrating through the fixed seat 502 is arranged on the fixed seat 502, and the guide rod 504 can slide relative to the fixed seat 502.

[0039] The clamping plate 506 is fixedly arranged at one end of the guide rod 504. A end plate 505 is fixedly arranged at the other end of the guide rod 504. A second spring 503 is arranged between the end plate 505 and the fixed seat 502. The clamping plate 506 is clamped tightly on the inlet of the sludge pump by the elastic force of the second spring 503.

[0040] The clamping plate 506 is stuck at the inlet of the sludge pump, and the clamping plate 506 is fixed on the guide rod 504. The guide rod 504 can slide on the fixed seat 502, thereby adjusting the position of the clamping plate 506 to adapt to the inlets of sludge pumps of different sizes, and further enabling this device to be used on sludge pumps of different sizes.

[0041] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
