Description

Technical Field

[0001] The utility model relates to the technical field of sewage pumps, in particular to a filtering device of a sewage pump. Background Art

[0002] The sewage pump filter is a device used to remove solid particles and impurities from sewage or wastewater before discharging it. This device is usually installed in front of the sewage pump to prevent impurities from entering the pump, thereby protecting the pump from damage, extending its service life, and ensuring the normal operation of the system;

[0003] The existing patent CN218266534U filtering device is provided with a motor, a rotating rod, an impeller and an anti-blocking mechanism. When the sewage pump body is working to discharge sewage, the anti-blocking mechanism can effectively prevent larger debris in the sewage from entering the interior of the sewage pump body, so that the interior of the sewage pump body is not easily blocked when the sewage pump body is working, and normal sewage discharge can be performed. At the same time, a cleaning mechanism is also provided. When the motor drives the rotating rod to rotate, the rotating rod rotates and drives the cleaning brush to rotate, so that the filter screen can be cleaned by the cleaning brush to prevent the filter screen from being blocked and affecting the normal operation of the sewage pump body, thereby further improving the sewage discharge capacity of the sewage pump body;

[0004] However, in this patent, sewage is filtered only by setting a filter plate. Although it has a certain effect, the filter plate is also prone to clogging. Further cleaning of the filter plate by a rotating cleaning brush can only clean the impurities on the surface of the filter plate, and cannot remove the impurities blocked in the filter holes. Therefore, the utility model proposes a filtering device for a sewage pump. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings in the prior art and to provide a filtering device for a sewage pump.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a filter device of a sewage pump, comprising a filter body, the filter body comprising a sleeve, a filter plate is embedded and installed on the top of the sleeve, a mounting frame is provided on the top of the sleeve, a cleaning component is rotatably connected between the mounting frame and the filter plate, a mounting seat is provided at the bottom of the filter plate, and a dredging component is rotatably connected to the mounting seat;

[0007] The dredging assembly includes a connecting plate, which is rotatably connected to a mounting seat, a mounting plate is arranged on the connecting plate, a dredging plate is arranged on the top of the mounting plate, and a water trough is provided on the mounting plate between the two dredging plates.

[0008] As a preferred embodiment, a filter groove is provided on the filter plate, the position distribution of the filter groove is the same as that of the dredging plate, and the length of the filter groove is greater than the length of the dredging plate.

[0009] The beneficial effect of adopting the above further scheme is that when the sewage is filtered through the filter groove opened on the filter plate, impurities larger than the filter groove will be blocked and cannot enter the interior of the casing. When the filter groove is blocked, the blockage can be pushed out by the action of the dredging plate, thereby ensuring the smooth flow of the filter groove.

[0010] As a preferred embodiment, the cleaning assembly includes a turbine blade and a scraper seat, the turbine blade is arranged on the top of the scraper seat, a rotating shaft is arranged between the turbine blade and the scraper seat, and the turbine blade and the scraper seat are rotatably connected between the filter plate and the mounting frame through the rotating shaft.

[0011] The beneficial effect of adopting the above-mentioned further scheme is: the impurities on the filter plate and the impurities pushed out by the dredging plate are cleaned by the cleaning component, and the turbine blades are driven to rotate by the water flow, so that the scraper seat in contact with the filter plate rotates. Through the rotation of the scraper seat, the impurities on the filter plate can be guided to the outside and separated from the filter plate, thereby achieving the cleaning effect.

[0012] As a preferred embodiment, a limit plate is provided on the inner wall of the sleeve below the dredging component, and the inner wall diameter of the limit plate is smaller than the outer wall diameter of the mounting plate.

[0013] The beneficial effect of adopting the above-mentioned further scheme is: the dredging component is limited by the limit plate. When the water flow hits the mounting plate, the mounting plates on both sides are tilted. The setting of the limit plate can prevent the dredging component from tilting too much, causing the dredging plate to be pushed out of the filter tank and contact the rotating scraper seat, resulting in collision and damage between the two.

[0014] As a preferred embodiment, the top of the dredging plate is an inclined surface, and the inclination angle of the dredging plate increases from the outside to the inside.

[0015] The beneficial effect of adopting the above further scheme is: through the design of the inclined surface on the top of the dredging plate, after the dredging assembly is tilted, the dredging plate at one end of the filter tank is on the same horizontal line as the filter tank, avoiding damage caused by collision between the exposed dredging plate and the scraper seat.

[0016] As a preferred embodiment, two mounting plates are provided, and the two mounting plates are symmetrical to each other at the center of the connecting plate.

[0017] The beneficial effect of adopting the above further scheme is: after the water flows into the interior of the sleeve through the two mounting plates, it contacts the mounting plates, causing the dredging component to tilt. At this time, under the action of the lever principle and the balance principle, it reciprocates up and down to dredge the blockage in the filter tank.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] 1. In the utility model, through the setting of the dredging component, after the water flows into the inside of the casing, it will first drive the dredging component to tilt to one side, and then drive the mounting plates on both sides to perform up and down reciprocating motion under the action of the lever principle and the balance principle. During the movement, the mounting plates are first limited by the limiting plates to prevent the mounting plates from tilting too much. Secondly, under the action of the dredging plates, the blockages in the filter tank are ejected to achieve the dredging effect. The dredging component is a reciprocating motion, which can always keep the filter tank unobstructed, thereby improving the stability of the device when in use.

[0020] 2. In the utility model, the impurities on the filter plate can be guided to the surroundings through the design of the cleaning component. When water flows, the cleaning component is driven to rotate under the action of the turbine blades. At this time, the scraper seat is also in a rotating state. The impurities on the surface of the filter plate are scraped out through the scraper seat, and under the action of centrifugal force, the impurities are thrown out to the surroundings to achieve a cleaning effect, thereby improving the practicality of the device.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example 1

[0030] like Figure 1-5 As shown, the utility model provides a technical solution: a filter device for a sewage pump, comprising a filter body 1, the filter body 1 comprises a sleeve 2, a filter plate 6 is embedded and installed on the top of the sleeve 2, a mounting frame 3 is provided on the top of the sleeve 2, a cleaning component 4 is rotatably connected between the mounting frame 3 and the filter plate 6, a mounting seat 61 is provided at the bottom of the filter plate 6, and a dredging component 5 is rotatably connected to the mounting seat 61;

[0031] The dredging assembly 5 includes a connecting plate 51, which is rotatably connected to the mounting seat 61. A mounting plate 52 is provided on the connecting plate 51, a dredging plate 53 is provided on the top of the mounting plate 52, and a water trough 54 is provided on the mounting plate 52 between the two dredging plates 53.

[0032] like Figure 4 As shown, a filter groove 62 is provided on the filter plate 6, and the position distribution of the filter groove 62 is the same as that of the dredging plate 53. The length of the filter groove 62 is greater than the length of the dredging plate 53. Through the design of the cleaning component 4, the impurities on the filter plate 6 can be discharged to the surroundings. When water flows, under the action of the turbine blades 41, the cleaning component 4 is driven to rotate. At this time, the scraper seat 43 is also in a rotating state. The impurities on the surface of the filter plate 6 are scraped out through the scraper seat 43, and under the action of centrifugal force, the impurities are thrown out to the surroundings to achieve a cleaning effect, thereby improving the practicability of the device.

[0033] Example 2

[0034] like Figure 5As shown, the cleaning component 4 includes a turbine blade 41 and a scraper seat 43. The turbine blade 41 is arranged on the top of the scraper seat 43. A rotating shaft 42 is arranged between the turbine blade 41 and the scraper seat 43. The turbine blade 41 and the scraper seat 43 are rotatably connected between the filter plate 6 and the mounting frame 3 through the rotating shaft 42. The impurities on the filter plate 6 and the impurities pushed out by the dredging plate 53 are cleaned by the cleaning component 4. The turbine blade 41 is driven to rotate by the water flow, so that the scraper seat 43 in contact with the filter plate 6 rotates. Through the rotation of the scraper seat 43, the impurities on the filter plate 6 can be guided to the outside to separate them from the filter plate 6, thereby achieving a cleaning effect.

[0035] like Figure 3 As shown, a limiting plate 21 is provided on the inner wall of the sleeve 2 below the clearing component 5. The inner wall diameter of the limiting plate 21 is smaller than the outer wall diameter of the mounting plate 52. The clearing component 5 is limited by the limiting plate 21. When the water flow hits the mounting plate 52, the mounting plates 52 on both sides are tilted. The setting of the limiting plate 21 can prevent the clearing component 5 from tilting too much, so that the clearing plate 53 is pushed out of the filter tank 62 and contacts the rotating scraper seat 43, resulting in a collision between the two and damage.

[0036] like Figure 4 As shown, the top of the dredging plate 53 is a slope, and the inclination angle of the dredging plate 53 increases from the outside to the inside. Through the design of the top slope of the dredging plate 53, after the dredging component 5 is tilted, the dredging plate 53 at one end of the filter tank 62 is on the same horizontal line as the filter tank 62, avoiding the dredging plate 53 being exposed and in contact with the scraper seat 43, and colliding with each other to cause damage.

[0037] like Figure 4 As shown, there are two mounting plates 52, and the two mounting plates 52 are symmetrical to each other at the center of the connecting plate 51. After water flows into the interior of the sleeve 2 through the two mounting plates 52, it contacts the mounting plates 52, causing the dredging component 5 to tilt. At this time, under the action of the lever principle and the balance principle, it reciprocates up and down to dredge the blockage in the filter tank 62.

[0038] Working principle:

[0039] like Figure 1-5As shown, first, the filter body 1 is fixedly connected to the sewage pump through the connecting pipe, and then the filter body 1 is placed in the sewage. When the water flows into the sleeve 2, it will first drive the dredging component 5 to tilt to one side, and then, under the action of the lever principle and the balance principle, it will drive the mounting plates 52 on both sides to perform up and down reciprocating motion. During the movement, the mounting plates 52 are first limited by the limiting plates 21 to prevent the mounting plates 52 from tilting too much. Secondly, under the action of the dredging plates 53, the blockages in the filter tank 62 are ejected to achieve the dredging effect. The dredging component 5 is a reciprocating motion, which can always keep the filter tank 62 unobstructed. When water flows, under the action of the turbine blades 41, the cleaning component 4 is driven to rotate. At this time, the scraper seat 43 is also in a rotating state, and the impurities on the surface of the filter plate 6 are scraped out by the scraper seat 43, and under the action of centrifugal force, the impurities are thrown out to the surroundings to achieve a cleaning effect.
