Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chemical processing technology, and in particular relates to a sewage pump used in chemical processing. Background Technology
[0002] In chemical production processes, large quantities of wastewater containing various chemicals and particulate matter are generated. If this wastewater is discharged directly without proper treatment, it will cause serious environmental pollution. Therefore, efficient treatment of chemical wastewater is a crucial aspect of the sustainable development of the chemical industry. As a key piece of equipment in chemical wastewater transportation and treatment systems, the operational stability and service life of sewage pumps directly affect the efficiency and cost of wastewater treatment. Currently, commonly used chemical wastewater sewage pumps often face clogging problems due to the large amount of particulate matter in the wastewater. These particles may be residues from chemical reactions, undissolved raw material particles, etc. When they enter the sewage pump with the wastewater, they cause severe wear to the pump impeller, pump casing, and other components, not only reducing the pump's working efficiency but also significantly shortening its service life, requiring frequent maintenance and replacement, and increasing the company's operating costs.
[0003] To address the issues of clogging and wear in sewage pumps, some existing technologies have incorporated filtration devices, such as installing a filter screen at the pump's inlet. However, after a period of use, the filter screen's mesh is easily clogged by particles, leading to reduced water flow and affecting the normal operation of the sewage pump. Regular cleaning or replacement of the filter screen is necessary, which is cumbersome and impacts production efficiency. Furthermore, for some small or sticky particles, the filter screen's filtration effect is not ideal, and it still cannot effectively prevent these particles from damaging the sewage pump.
[0004] Therefore, developing a method that can efficiently separate particulate matter from chemical wastewater and reduce wear and clogging of the sewage pump body has become an urgent problem to be solved in the field of chemical wastewater treatment. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, this utility model provides a sewage pump for chemical processing.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a sewage pump for chemical processing, comprising a main body for discharging chemical wastewater, wherein the inlet end of the main body is provided with a separation component to prevent particulate matter from clogging, the separation component includes a separation box connected to the inlet end of the main body, the separation box has a guide cavity inside, the upper middle part of the guide cavity is cylindrical, the lower middle part of the guide cavity is funnel-shaped, the top of one side of the separation box is provided with an inlet pipe communicating with the guide cavity, the inlet pipe is tangential to the inner wall of the guide cavity, and the bottom of the separation box is provided with a collection tank connected by a connector, wherein the sewage entering along the tangential direction of the inner wall of the guide cavity will form a vortex, and the particulate matter in the wastewater will move towards the inner wall of the guide cavity under the centrifugal force generated by the vortex.
[0007] Optionally, the upper part of the flow guiding cavity is provided with a spiral flow guiding strip.
[0008] Optionally, the connector includes a rotating ring, with an upper spiral groove in the upper middle part and a lower spiral tube in the lower middle part. The bottom of the separation box is provided with an upper spiral tube that mates with the upper spiral groove, and the top of the collection tank is provided with a lower spiral groove that mates with the lower spiral tube.
[0009] Optionally, the interior of the lower spiral tube is provided with a downwardly extending support, and the middle of the support is rotatably connected to an upwardly extending rotating rod. The top of the rotating rod is provided with a blade that cooperates with the guide strip.
[0010] Optionally, the rotating rod has a spiral-shaped unblocking strip in the middle.
[0011] Optionally, the outer wall of the rotating ring is provided with a pattern to increase friction.
[0012] In summary, the beneficial effects of this utility model are as follows: by setting up a separation component, sewage enters the guide cavity along the tangential direction of the inlet pipe and forms a swirling flow. Under the action of centrifugal force, particulate matter moves towards the inner wall and falls into the collection tank, reducing the amount of particulate matter entering the main body of the sewage pump. The spiral guide strip in the upper part of the guide cavity further enhances the swirling effect. Together with the blades that work in synergy with the guide strip, the particulate matter separation efficiency is improved, effectively avoiding wear and blockage of the main body of the sewage pump by particulate matter, extending the service life of the main equipment, and reducing the cost caused by frequent maintenance and replacement.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] refer to Figure 1-6 A sewage pump for chemical processing includes a main body 1 for discharging chemical wastewater. The inlet end of the main body 1 is provided with a separation component to prevent particulate matter from clogging. The separation component includes a separation box 2 connected to the inlet end of the main body 1. The separation box 2 has a guide cavity 3 inside. The upper middle part of the guide cavity 3 is cylindrical, and the lower middle part of the guide cavity 3 is funnel-shaped. The top of one side of the separation box 2 is provided with an inlet pipe 4 communicating with the guide cavity 3. The inlet pipe 4 is tangential to the inner wall of the guide cavity 3. The bottom of the separation box 2 is provided with a collection tank 5 connected by a connector. Sewage entering along the tangential direction of the inner wall of the guide cavity 3 will form a vortex. The particulate matter in the wastewater will move towards the inner wall of the guide cavity 3 under the centrifugal force generated by the vortex.
[0022] The main body 1 is a commonly used chemical wastewater discharge pump. The separation tank 2 is connected to the main body 1. The guide cavity 3 is opened inside the separation tank 2. The inlet pipe 4 is connected to the top of the side wall of the guide cavity 3. The collection tank 5 is connected to the separation tank 2. The chemical wastewater in the inlet pipe 4 will enter the guide cavity 3 tangentially. At this time, the chemical wastewater in the guide cavity 3 will form a vortex. The chemical wastewater in the vortex state will generate centrifugal force. The particulate matter in the chemical wastewater will move towards the inner wall under the action of centrifugal force and move down along the inner wall of the guide cavity 3 into the collection tank 5.
[0023] More specifically, the upper middle part of the guide cavity 3 is provided with a spiral guide strip 6, which is integrally formed on the inner wall of the guide cavity 3. The spiral shape of the guide strip 6 can further promote the formation of sewage vortex in the guide cavity 3 and improve the separation effect of particulate matter in chemical sewage.
[0024] More specifically, the connector includes a rotating ring 7, with an upper screw groove 8 in the upper middle part and a lower spiral tube 9 in the lower middle part. The bottom of the separation box 2 has an upper spiral tube 10 that mates with the upper screw groove 8, and the top of the collection tank 5 has a lower screw groove 11 that mates with the lower spiral tube 9. The upper screw groove 8 is located in the upper middle part of the rotating ring 7, the lower spiral tube 9 is integrally formed in the lower middle part of the rotating ring 7, the upper spiral tube 10 is integrally formed in the bottom of the separation box 2, and the lower screw groove 11 is located in the top of the collection tank 5. The rotating ring 7 can be screwed to the bottom of the separation box 2 through the upper screw groove 8 and the upper spiral tube 10, and the rotating ring 7 can be connected to the collection tank 5 through the lower screw groove 11 and the lower spiral tube 9. The collection tank 5, the rotating ring 7, and the separation box 2 can be separated from each other, making it convenient to remove the collection tank 5 for cleaning.
[0025] More specifically, the lower spiral tube 9 has a downwardly extending support 12 inside. The middle of the support 12 is rotatably connected to an upwardly extending rotating rod 13. The top of the rotating rod 13 is provided with a blade 14 that cooperates with the guide strip 6. The support 12 is integrally formed inside the lower spiral tube 9. The support 12 does not affect the normal entry of particulate matter into the collection tank 5. The rotating rod 13 is rotatably connected to the support 12, and the blade 14 is fixed to the top of the rotating rod 13. The cooperation between the blade 14 and the guide strip 6 can promote the formation of vortex and improve the separation of particulate matter in chemical wastewater.
[0026] More specifically, the rotating rod 13 is provided with a spiral-shaped unblocking strip 15 in the middle. The unblocking strip 15 is integrally formed in the middle of the rotating rod 13, which can prevent particles from clogging near the rotating ring 7.
[0027] More specifically, the outer wall of the rotating ring 7 is provided with a pattern to increase friction. The pattern can increase the friction of the rotating ring 7, which can facilitate the fixing and separation of the collection tank 5, the rotating ring 7, and the separation box 2.
[0028] The specific working principle is as follows: When this sewage pump is working, the chemical wastewater first enters the guide cavity 3 tangentially through the inlet pipe 4. The chemical wastewater will form a swirling flow under the action of the guide strip 6. The chemical wastewater in the swirling state will generate centrifugal force. Under the action of centrifugal force, the particles in the chemical wastewater will move towards the inner wall of the guide cavity 3 and move downward under the action of their own gravity until these particles enter the collection tank 5. The separated chemical wastewater will enter the main body 1 and be discharged.
[0029] In the swirling state, the swirling chemical wastewater will drive the rotating rod 13 to rotate through the blade 14. The unblocking strip 15 on the rotating rod 13 will also rotate, which can prevent particles from clogging the lower part of the guide cavity 3. When the particles in the collection tank 5 reach a certain amount, the sewage pump is turned off, and the collection tank 5 is removed with the rotating ring 7 fixed. At this time, the particles collected in the collection tank 5 can be cleaned.
[0030] More specifically, the inlet end of the main body 1 is connected to a guide pipe 16, which penetrates the top wall of the separation tank 2 and extends to the upper middle part of the guide cavity 3. A filter screen 19 is provided on the outside of the guide pipe 16. The guide pipe 16 can conveniently input the separated chemical wastewater into the main body 1. The guide pipe 16 extends into the guide cavity 3, which can prevent the chemical wastewater in the inlet pipe 4 from directly entering the sewage pump. The filter screen 19 can filter the chemical wastewater entering the sewage pump again.
[0031] More specifically, sealing rings 17 are provided between the separation box 2 and the rotating ring 7, and between the collection tank 5 and the rotating ring 7, respectively. The sealing rings 17 can increase the sealing between the rotating ring 7 and the separation box 2 and the collection tank 5.
[0032] More specifically, the side wall of the collection tank 5 is provided with a transparent glass window 18, which allows observation of the amount of particulate matter and prevents excessive particulate matter from entering the collection tank 5.
