Description

Technical Field

[0001] The invention belongs to the technical field of pumps and specifically discloses an axial flow pump for chemical industry. Background Art

[0002] An axial flow pump is a non-variable displacement pump. As a vane pump, its working principle relies on the force exerted by the rotating impeller blades on the liquid to transport the liquid along the axial direction. Axial flow pumps are characterized by high flow, low head, and high specific speed, making them suitable for scenarios with high flow and low head.

[0003] A search revealed a Chinese patent application for an axial flow pump for chemical industry (publication number: CN118030626B). This patent describes a filter plate installed inside a water inlet pipe. When the sieve holes on one side of the filter plate are clogged with silt, the filter plate is rotated 180°, with the side with the previously blocked sieve holes becoming the backwater side and the side not clogged with silt becoming the waterside. This allows water to easily remove the silt from the sieve holes as it flows through them. Repeated flipping of the filter plate allows the silt in the sieve holes to be removed in a timely manner, guided by the direction of the water flow.

[0004] However, in actual use, there are the following problems: First, the sludge will still be transported to the next treatment link through the pump body after backwashing, which undoubtedly increases the difficulty of subsequent treatment; second, the staff needs to flip the sieve plate regularly, and if the flip is not timely, it is easy to cause blockage and excessive pressure, resulting in damage to the conveying pipeline.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] like Figures 1-10 The axial flow pump for chemical industry shown in the figure comprises a pump body 1 and a controller 4. A filter mechanism 2 is provided at the bottom of the pump body 1, and a sewage discharge assembly 3 is provided on the surface of the filter mechanism 2.

[0035] Among them, the filtering mechanism 2 includes a mounting pipe 201 connected to the liquid inlet end of the pump body 1, and the inner wall of the mounting pipe 201 is fixedly connected with a second partition 203 and a first partition 202 in sequence from top to bottom. The second partition 203 and the first partition 202 are both inclined. A sewage discharge area is formed between the second partition 203 and the first partition 202, an outlet area is formed between the top of the second partition 203 and the interior of the mounting pipe 201, and an inlet area is formed between the bottom of the first partition 202 and the interior of the mounting pipe 201. A water inlet component 21 is provided on the surface of the mounting pipe 201, a processing component 22 is provided on the surface of the second partition 203, and a hydraulic pressure sensor 204 located inside the sewage discharge area is embedded and installed on the surface of the second partition 203;

[0036] The hydraulic sensor 204 can detect the water pressure inside the sewage discharge area, and can transmit a signal to the controller 4 when the water pressure exceeds a preset value. Among them, the controller 4 is a PLC programmable controller, and the specific model should be selected according to actual conditions. The commands preset on the PLC programmable controller can be executed according to the preset commands after it receives the signal transmitted by the hydraulic sensor 204.

[0037] like Figures 1-10 As shown, the water inlet assembly 21 includes an inlet shell 2102 arranged on the surface of the mounting pipe 201 and connected to the inlet area, the surface of the mounting pipe 201 is fixedly connected to the mounting shell 2101 connected to the sewage discharge area, the other end of the inlet shell 2102 is connected to the interior of the mounting shell 2101, the interior of the mounting shell 2101 is fixedly connected to a scraper 2103, the mounting shell 2101 is rotatably connected to a rotating block 2105 away from the inner wall of the mounting pipe 201, the other side of the rotating block 2105 is fixedly connected to a connecting tube 2104, the surface of the connecting tube 2104 is provided with evenly distributed filter holes 2106, the other end of the connecting tube 2104 passes through the mounting pipe 201 and the second partition 203 in sequence and is connected to the outlet area, and the other end of the connecting tube 2104 is rotatably connected to the inner wall of the second partition 203.

[0038] When the pump body 1 is started, it can introduce the fluid through the introduction area, and under the action of the introduction shell 2102, it is introduced into the interior of the installation shell 2101. In this process, due to the setting of the filter hole 2106 on the connecting cylinder 2104, dirt and impurities can be intercepted, so that the fluid passes through the filter hole 2106 and is introduced into the outlet area through the connecting cylinder 2104 and is discharged through the liquid outlet end of the pump body 1 after being pumped by the pump body 1. In this process, the intercepted dirt and impurities can be pushed by the fluid to the internal storage of the sewage discharge area. As the dirt and impurities in the sewage discharge area increase and the impurities on the surface of the connecting cylinder 2104 increase, the passing rate of the filter hole 2106 for the conveyed fluid can be gradually affected. , thereby increasing the pressure inside the sewage discharge area. When the hydraulic sensor 204 detects that the pressure exceeds the preset value, it transmits a signal to the controller 4, and under the action of the controller 4, the sewage discharge component 3 is started to cooperate with the processing component 22 to realize the cleaning of the surface of the connecting cylinder 2104. At the same time, it can realize the discharge of the sewage collected inside the sewage discharge area. In the process of the operation of the processing component 22 and the sewage discharge component 3, it can cooperate with the scraper 2103 to enhance the cleaning effect of the impurities and dirt adhering to the surface of the connecting cylinder 2104. There is no need for staff to stop the machine for processing. At the same time, it avoids the situation that the traditional filtering structure is located below the water level and is inconvenient for cleaning. It is easy to operate and has a high degree of automation.

[0039] The fluid introduced through the inlet shell 2102 can impact the surface of the connecting tube 2104, and one end of the connecting tube 2104 is rotatably connected to the inner wall of the second partition 203 and the other end is rotatably connected to the inner wall of the mounting shell 2101 through the rotating block 2105, which will produce a slight rotation. At this time, the scraper 2103 can scrape off the dirt and impurities on the surface of the connecting tube 2104 to reduce the impact of adhesion on the passage of the fluid. Since the connection point between the inlet shell 2102 and the mounting shell 2101 is located at the center of the mounting shell 2101, the rotation caused by the impact on the connecting tube 2104 is relatively slight and will not affect the normal filtering effect.

[0040] like Figures 1-10 As shown, the inner wall of the mounting shell 2101 is rotatably connected to a rotating ring 2108, the connecting cylinder 2104 is located on the inner side of the rotating ring 2108, the inner side of the rotating ring 2108 is fixedly connected to a push plate 2109, and the outer side of the rotating ring 2108 is fixedly connected to evenly distributed driving blades 2110.

[0041] A connecting tube 2107 is provided inside the connecting tube 2104 , one end of the connecting tube 2107 is fixedly connected to a fixing rod fixedly connected to the inner wall of the rotating block 2105 , and the other end of the connecting tube 2107 passes through the connecting tube 2104 and the mounting tube 201 in sequence.

[0042] A connecting cavity 2111 communicating with the connecting tube 2107 is provided inside the fixed rod, a through hole is provided on the surface of the rotating block 2105, an adjusting cavity 2113 communicating with the through hole is provided inside the rotating block 2105, a through hole 2112 communicating with the connecting cavity 2111 is provided on the inner wall of the adjusting cavity 2113, a slide 2114 is slidably connected to the inner wall of the adjusting cavity 2113, an adjusting rod 2115 is fixedly connected to the side of the slide 2114 away from the through hole 2112, and a first spring 2116 is fixedly connected between the surface of the slide 2114 and the inner wall of the adjusting cavity 2113.

[0043] The driving blade 2110 set on the surface of the rotating ring 2108 can be pushed by the fluid introduced by the inlet shell 2102 to rotate the rotating ring 2108, and in this process, it can drive the push plate 2109 to rotate synchronously. Under normal circumstances, the setting of the first spring 2116 can limit the position of the slide plate 2114 so that the adjusting rod 2115 cannot pass through the through hole to enter between the inner side of the rotating ring 2108 and the rotating block 2105. At this time, the rotation of the rotating ring 2108 drives the rotation of the push plate 2109 without affecting the position of the rotating block 2105.

[0044] like Figures 1-10 As shown, the processing component 22 includes a mounting block 2203 fixedly connected to the side of the second partition 203 away from the sewage discharge area, one end of the mounting block 2203 extends to the opening of the connecting tube 2104 away from the mounting shell 2101, and the surface of the mounting block 2203 is fixedly connected to a connecting rod 2204 extending to the inside of the connecting tube 2104, and the surface of the connecting rod 2204 is provided with top rods 2206 evenly distributed and corresponding to the filter holes 2106, and a sliding rod 2207 is provided inside the top rod 2206, and the other end of the sliding rod 2207 passes through the top rod 2206 and is fixedly connected to the surface of the connecting rod 2204, and the other end of the sliding rod 2207 is fixedly connected to a fixing plate 2208 slidably connected to the inner wall of the top rod 2206, and a second spring 2205 is fixedly connected between the surface of the fixing plate 2208 and the inner wall of the top rod 2206.

[0045] The processing assembly 22 further includes a plurality of evenly distributed chutes 2201 opened on the inner side of the connecting tube 2104 , the filter holes 2106 are connected to adjacent chutes 2201 , and two symmetrically distributed guide blocks 2202 are fixedly connected to the inner wall of the filter hole 2106 .

[0046] The second spring 2205 can maintain the position of the top rod 2206 so that it can be inserted into the filter hole 2106. When the connecting cylinder 2104 rotates, the guide block 2202 can be used to squeeze the end of the top rod 2206, so that it slides along the surface of the sliding rod 2207 and stretches the second spring 2205 (see Figure 10The second spring 2205 is in the stretched state), at this time, the sliding rod 2207 can slide along the inner wall of the chute 2201 without affecting the rotation of the connecting cylinder 2104, until it moves to the next filter hole 2106. It can be driven to reset under the action of the second spring 2205 and inserted into the inside of the filter hole 2106 to dredge the filter hole 2106. In combination with the scraper 2103, the cleaning effect of the filter hole 2106 can be effectively improved;

[0047] Specifically, the angle between the scraper 2103 and the connecting rod 2204 is 30 degrees, which can effectively prevent the dredged impurities from being blocked by the scraper 2103 and affecting the discharge of the dredged impurities.

[0048] like Figures 1-10 As shown, the sewage discharge component 3 includes a sewage discharge pipe 312 arranged on the surface of the mounting tube 201 and connected to the sewage discharge area, a fixed cylinder 302 is provided on the surface of the sewage discharge pipe 312, and two sewage discharge holes are opened on the surface of the fixed cylinder 302 for connecting the interior of the fixed cylinder 302 with the sewage discharge pipe 312, a counterweight block 307 is slidably connected to the inner wall of the fixed cylinder 302, an electromagnet 303 is provided on the inner top wall of the fixed cylinder 302, and the counterweight block 307 is a ferromagnetic metal material component.

[0049] The top of the fixed cylinder 302 is fixedly connected to the liquid storage cylinder 305, and the top of the counterweight block 307 is fixedly connected to the extrusion rod 304. The upper end of the extrusion rod 304 passes through the fixed cylinder 302 and is slidably connected to the inner wall of the liquid storage cylinder 305. The interior of the liquid storage cylinder 305 is filled with hydraulic oil.

[0050] The sewage discharge component 3 also includes a fixed block 301 fixedly connected to the surface of the mounting pipe 201, and the fixed block 301 is rotatably connected to a rotating disk 308 inside. An inlet cavity 311 is provided inside the rotating disk 308, and the surface of the rotating disk 308 is provided with connecting holes 310 evenly distributed and connected to the inlet cavity 311. A connecting cavity 309 connected to the connecting holes 310 is provided inside the fixed block 301, and the top of the liquid storage cylinder 305 is connected to a conduit 306, and the other end of the conduit 306 is connected to the connecting cavity 309. One end of the connecting pipe 2107 is fixedly connected to the surface of the rotating disk 308 and is connected to the inlet cavity 311.

[0051] When the hydraulic sensor 204 detects that the pressure inside the sewage discharge area exceeds a preset value, the signal is transmitted to the controller 4. The controller 4 activates the electromagnet 303 to cause the electromagnet 303 to attract the counterweight 307. At this time, the counterweight 307 is attracted and moves upward along the inner wall of the fixed cylinder 302 so as not to block the two sewage discharge holes. Then, the dirt and impurities inside the sewage discharge area can be pushed by the fluid to be discharged through the sewage discharge pipe 312, thereby reducing the accumulation of dirt and impurities inside the sewage discharge area and thus reducing the pressure inside the sewage discharge area. After 5 minutes of sewage discharge, the electromagnet 303 is turned off, and the counterweight 307 is reset under the action of gravity to re-block the connection between the two sewage discharge holes, so that the fluid is no longer discharged through the sewage discharge pipe 312.

[0052] At the same time, in the process of the electromagnet 303 adsorbing the counterweight block 307 and moving it upward, it can drive the squeezing rod 304 to squeeze the hydraulic oil stored in the liquid storage cylinder 305, so that the hydraulic oil is injected into the interior of the connecting pipe 2107 through the conduit 306, the connecting cavity 309 and the connecting hole 310, and the hydraulic oil is introduced into the interior of the adjusting cavity 2113 through the connecting cavity 2111 through the through hole 2112, thereby pushing the slide plate 2114 so that it overcomes the spring of the first spring 2116 and pushes the adjusting rod 2115 out of the interior of the adjusting cavity 2113 and inserts it between the rotating ring 2108 and the rotating block 2105, so that in the process of the fluid pushing the rotating ring 2108 to rotate, the push plate 2109 can be used to push the adjusting rod 2115 to drive the rotating block 2105 to rotate, and cooperate with the processing component 22 and the scraper 2103 to improve the cleaning effect of the filter hole 2106, so that the cleaned dirt can be discharged by the fluid during the sewage discharge process, thereby achieving the purpose of self-cleaning, without the need for manual cleaning by the staff, and easy operation.

[0053] Working principle: When the pump body 1 is started, the fluid can be introduced through the introduction area, and under the action of the introduction shell 2102, it is introduced into the interior of the installation shell 2101. In this process, due to the setting of the filter hole 2106 on the connecting cylinder 2104, the dirt and impurities can be intercepted, so that the fluid passes through the filter hole 2106 and is introduced into the outlet area through the connecting cylinder 2104 and is discharged through the liquid outlet end of the pump body 1 after being pumped by the pump body 1. In this process, the trapped dirt and impurities can be pushed by the fluid to the internal storage of the sewage discharge area. As the dirt and impurities in the sewage discharge area increase and the connection cylinder 2104 The increase in surface impurities can gradually affect the passage rate of the filter pores 2106 for the conveyed fluid, thereby increasing the pressure inside the sewage discharge area. When the hydraulic sensor 204 detects that the pressure exceeds the preset value, it transmits a signal to the controller 4, and under the action of the controller 4, the sewage discharge component 3 is started to cooperate with the processing component 22 to realize the cleaning of the surface of the connecting cylinder 2104, and at the same time, it can realize the discharge of the dirt collected inside the sewage discharge area, and during the operation of the processing component 22 and the sewage discharge component 3, it can cooperate with the scraper 2103 to enhance the cleaning effect of impurities and dirt adhering to the surface of the connecting cylinder 2104.
