Description

Technical Field

[0001] This utility model relates to the field of sewage suction technology for sewage suction vehicles, specifically a sewage suction device for sewage suction vehicles. Background Technology

[0002] Currently, with the construction and development of cities, towns, and industrial and mining enterprises of all sizes in my country, people's requirements for environmental protection are getting higher and higher, and the workload is also increasing. At present, sewer flushing and sewage suction still follow the manual operation mode, which results in high labor intensity for workers and frequent poisoning accidents, making it difficult to promote and popularize the manual operation mode. Currently, sewage suction trucks on the market generally have both flushing and sewage suction functions.

[0003] The existing sewage suction devices for sewage suction trucks generally involve inserting a pipe into the area where sewage needs to be pumped, and then using a water pump and engine to pump the sewage into the sewage suction truck. However, the area where sewage needs to be pumped may contain a large number of stones and large pieces of silt. A large amount of stones and silt entering the sewage pipe can clog the sewage pipe, severely reducing the pumping speed, and may even cause the water pump to run dry, ultimately leading to a short circuit.

[0004] Therefore, we propose a vacuuming device for vacuum trucks to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a sewage suction device for a sewage suction truck, in order to solve the problem mentioned in the background art. The common method is to extend a pipe into the place where sewage needs to be pumped, and then use a water pump and engine to pump the sewage into the sewage suction truck. However, the place where sewage needs to be pumped may contain a large number of stones and large pieces of silt. A large number of stones and silt enter the sewage pipe and block the sewage pipe, which seriously reduces the sewage pumping speed and may even cause the water pump to run dry, ultimately leading to a short circuit.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a vacuum truck body and a sludge storage tank fixedly installed on the vacuum truck body. A filter assembly is provided on the sludge storage tank. The filter assembly includes a first chamber formed in the sludge storage tank, a sewage pump is installed in the first chamber, a connecting pipe is fixedly installed at the suction end of the sewage pump, two first lugs are fixedly installed on the side wall of the connecting pipe, screws are slidably installed on the two first lugs, nuts are threaded onto the axial side wall of the screws, a filter screen is slidably installed on the axial side wall of the screws, and a striking component for cleaning the filter screen is provided on the inner wall of the connecting pipe.

[0007] Preferably, the striking assembly includes two fixed blocks fixedly mounted on the filter screen, with a first rotating shaft rotating between the two fixed blocks. A striking rod is fixedly mounted on the axial sidewall of the first rotating shaft, and a torsion spring is provided between the striking rod and the fixed blocks. A second rotating shaft is rotatably mounted on the inner wall of the connecting pipe, and a waterwheel is fixedly mounted on the axial sidewall of the second rotating shaft. A connecting rod is fixedly mounted on the axial sidewall of the second rotating shaft, and a dispersing assembly is provided at the lower end of the filter screen.

[0008] Preferably, the dispersing component includes two second lugs slidably connected to the screw, and the two second lugs are jointly fixedly installed with a protective cylinder. The protective cylinder has a second chamber and several water inlet grooves. Several third rotating shafts are rotatably installed on the several water inlet grooves. Stirring blades are fixedly installed on the axial sidewalls of the several third rotating shafts. A cleaning component for cleaning the connecting pipe is provided on the first chamber.

[0009] Preferably, the cleaning assembly includes a water storage tank fixedly installed in the first chamber, an inlet pipe fixedly installed at the upper end of the water storage tank, a hole opened on the sludge storage tank, an inlet pipe groove opened at the upper end of the water storage tank, and a sludge discharge pipe provided at one end of the sewage pump.

[0010] Preferably, the striking rod is within the rotation radius of the connecting rod.

[0011] Preferably, the stirring blade does not come into contact with other stirring blades when it rotates.

[0012] Preferably, the size of the inlet pipe is larger than the size of the outlet pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. With the cooperation of the sewage pump, connecting pipe, discharge pipe, sludge storage tank, and inlet tank, large stones and large areas of silt are isolated and removed. With the cooperation of water flow and stirring blades, stones stuck in the inlet tank are knocked off, preventing the inlet tank from being blocked and causing the sewage pump to run dry, which could lead to a short circuit.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figures 1-4 The system includes a vacuum truck body 1 and a sludge storage tank 11 fixedly installed on the vacuum truck body 1. A filter assembly 2 is provided on the sludge storage tank 11. The filter assembly 2 includes a first chamber 51 opened on the sludge storage tank 11. A sewage pump 52 is provided on the first chamber 51. A connecting pipe 21 is fixedly installed on the suction end of the sewage pump 52. Two first lugs 22 are fixedly installed on the side wall of the connecting pipe 21. Screws 24 are slidably installed on the two first lugs 22. Nuts 25 are threadedly connected to the axial side wall of the screws 24. A filter screen 23 is slidably installed on the axial side wall of the screws 24. A striking assembly 3 for cleaning the filter screen 23 is provided on the inner wall of the connecting pipe 21.

[0024] The striking assembly 3 includes two fixed blocks 31 fixedly mounted on the filter screen 23. A first rotating shaft 32 rotates together between the two fixed blocks 31. A striking rod 33 is fixedly mounted on the axial side wall of the first rotating shaft 32. A torsion spring 34 is provided between the striking rod 33 and the fixed blocks 31. A second rotating shaft 35 is rotatably mounted on the inner wall of the connecting pipe 21. A waterwheel 36 is fixedly mounted on the axial side wall of the second rotating shaft 35. A connecting rod 37 is fixedly mounted on the axial side wall of the second rotating shaft 35. A dispersing assembly 4 is provided at the lower end of the filter screen 23.

[0025] The dispersing component 4 includes two second lugs 46 slidably connected to the screw 24. The two second lugs 46 are jointly fixedly installed with a protective cylinder 41. The protective cylinder 41 has a second chamber 42 and several water inlet grooves 43. The second chamber 42 is connected to the connecting pipe 21. Several third rotating shafts 44 are rotatably installed on the several water inlet grooves 43. Stirring blades 45 are fixedly installed on the axial sidewalls of the several third rotating shafts 44. A cleaning component 5 for cleaning the connecting pipe 21 is provided on the first chamber 51.

[0026] The striking rod 33 is within the rotation radius of the connecting rod 37. When the connecting rod 37 rotates, it can squeeze the striking rod 33, causing one end of the striking rod 33 to move away from the filter screen 23.

[0027] The stirring blade 45 will not come into contact with other stirring blades 45 when it rotates, thus preventing the stirring blade 45 from being unable to rotate.

[0028] In this embodiment: First, the connecting pipe 21 and the protective cylinder 41 are placed into the sewage to be pumped out. Then, the sewage pump 52 is started, and the sewage is pumped into the storage tank 11 through the connecting pipe 21 and the discharge pipe 57. Some large stones and large areas of silt are isolated through the inlet trough 43. However, stones of the same size as the inlet trough 43 can cause it to get stuck. At this time, the water flow drives the stirring blade 45 to rotate, which can knock the stones stuck in the inlet trough 43 off, preventing the inlet trough 43 from getting blocked and causing the sewage pump 52 to run dry, which could lead to a short circuit in the sewage pump 52. It can also break up the silt on the inlet trough 43 and further clean the inlet trough 43. During long-term operation, for some small Sludge will adhere to the surface of the filter screen 23, which will affect the sludge suction efficiency. The water flow will drive the waterwheel 36 to rotate, which in turn drives the connecting rod 37 to rotate. At this time, the connecting rod 37 will squeeze one end of the striking rod 33, causing the other end of the striking rod 33 to move away from the filter screen 23. After the connecting rod 37 leaves the striking rod 33, the striking rod 33 will strike the filter screen 23 through the action of the torsion spring 34, which will shake the sludge adsorbed on the filter screen 23 into the second chamber 42, thereby improving the sludge suction effect. Finally, after use, the connecting pipe 21 is taken out, and the protective cylinder 41 is removed by unscrewing the nut 25 and pulling out the screw 24, so that the small stones and sludge inside the protective cylinder 41 can be cleaned for the next use.

[0029] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 1 and Figure 5 The cleaning assembly 5 includes a water tank 53 fixedly installed in the first chamber 51. A water inlet pipe 55 is fixedly installed at the upper end of the water tank 53 and is connected to the water tank 53. A hole 54 is opened on the sludge storage tank 11. An inlet pipe groove 56 is opened at the upper end of the water tank 53. A sewage discharge pipe 57 is provided at one end of the sewage pump 52.

[0030] The size of the inlet pipe 56 is larger than the size of the drain pipe 57, and the drain pipe 57 can enter the water storage tank 53 through the inlet pipe 56.

[0031] In this embodiment: After the sludge suction is completed, the sludge adhering to the connecting pipe 21 needs to be treated. At this time, the drain pipe 57 is inserted into the water storage tank 53 through the inlet pipe groove 56. Then, the sewage pump 52 is reversed, and the drain pipe 57 pumps the water in the water storage tank 53 into the connecting pipe 21, thereby washing away the sludge adhering to the inner wall of the connecting pipe 21, making it convenient for the next use and improving the service life of the connecting pipe 21.
