Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a high-efficiency filtration device integrated with dust collection for water sprinkler trucks. Background Technology

[0002] Water sprinkler trucks are generally used to spray water on roads to capture dust, cool and humidify the environment, or to automatically water roadside green belts, improving their maintenance efficiency. Existing water sprinkler trucks are also being explored for road cleaning capabilities by equipping them with dust suction structures. However, when using existing water sprinkler trucks for dust suction, the presence of debris such as leaves and stones on the road surface is directly sucked in and filtered through the filter structure. This can easily cause significant impact damage to the filter structure and clog the filter pores, affecting filtration efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide an integrated high-efficiency filtration device for water truck dust collection, in order to solve the problem that the filter structure is easily damaged by the presence of impurities such as leaves and stones on the road surface during the use of existing water truck dust collection, and that the filter holes are blocked, thus affecting the filtration efficiency.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency filtration device integrating dust collection for water sprinkler trucks, comprising:

[0005] The cylinder has an inlet and a first outlet on its side, and one side of the inlet and the first outlet is tangent to the inner wall of the cylinder.

[0006] A filter structure is assembled at one end of the cylinder, and a primary filter layer and a high-efficiency filter layer are arranged sequentially inside the filter structure along the airflow direction. The air inlet end of the filter structure is equipped with a sealing mesh plate, and its air outlet end is connected to the second outlet.

[0007] An impurity collection box is assembled outside the cylinder, and the dirt collection chamber inside it is connected to the first discharge port.

[0008] As a further description of the above technical solution:

[0009] The inner wall of the cylinder extends outward from both sides of the first outlet in a tapered shape with a gradually decreasing cross-sectional size.

[0010] As a further description of the above technical solution:

[0011] The end of the sludge collection chamber near the first discharge port is provided with a wedge-shaped surface.

[0012] As a further description of the above technical solution:

[0013] One end of the cylinder is provided with an annular positioning seat. The filter structure passes through the positioning seat and is sealed and joined with the stepped platform inside the positioning seat by the side flange and sealing ring and fixed by bolts.

[0014] As a further description of the above technical solution:

[0015] The encapsulation mesh is mounted on the filter structure by bolts.

[0016] As a further description of the above technical solution:

[0017] A support ring is provided inside the cylinder, and several support rods radiate out from the outer side of the support ring. The outer ends of the support rods are positioned on the inner wall of the cylinder, and the support ring is sleeved on the filter structure.

[0018] As a further description of the above technical solution:

[0019] The cylinder is provided with positioning guide rails on both sides of the impurity collection box. The guide blocks extending from both sides of the impurity collection box slide and engage in the guide grooves on the inner side of the positioning guide rails. The sealing plate slides into the guide grooves and abuts against the end face of the impurity collection box. It is positioned on the positioning guide rails by bolts.

[0020] In summary, by adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0021] This utility model discloses a high-efficiency dust collection and filtration device integrated into a sprinkler truck. During operation, a negative pressure environment is created inside the cylinder via a fan connected to the second outlet. This allows the sprinkler truck's dust collection structure to draw dust from the road surface into the filtration device. The dust-laden airflow enters the cylinder tangentially through the inlet, causing large, heavy objects such as leaves and stones to rotate along the inner wall of the cylinder due to centrifugal force and be tangentially guided into the impurity collection box through the first outlet for collection. This separation structure prevents impurities from directly impacting the filtration structure and causing damage, or from clogging the filter pores and affecting filtration efficiency. The dust-laden airflow is then drawn into the filtration structure, passing through multiple filtration layers for purification before being discharged through the second outlet, thus achieving high-efficiency filtration. Both the filtration structure and the impurity collection box on the cylinder can be easily disassembled and reassembled to ensure the device's high-efficiency filtration performance.

[0029] Please see Figure 1-2 This utility model provides a technical solution: a high-efficiency filtration device integrating dust collection for water sprinkler trucks, comprising:

[0030] The cylinder 1 has an inlet 2 and a first outlet 3 arranged on its side, and one side of the inlet 2 and the first outlet 3 is tangent to the inner wall of the cylinder 1.

[0031] The filter structure 4 is assembled at one end of the cylinder 1. A primary filter layer 5 and a high-efficiency filter layer 6 are arranged sequentially inside the filter structure 4 along the airflow direction. An encapsulation mesh plate 7 is provided at the air inlet end of the filter structure 4, and its air outlet end is connected to the second outlet 8. The filter holes and mesh openings on the encapsulation mesh plate 7, the primary filter layer 5, and the high-efficiency filter layer 6 decrease in size in sequence, thereby achieving multi-stage filtration of the dust-laden airflow collected by the dust collection component of the sprinkler truck and improving the cleanliness of the exhaust air.

[0032] Impurity collection box 9 is assembled outside the cylinder 1, and the dirt collection chamber 10 inside it is connected to the first discharge port 3.

[0033] The inner wall of the cylinder 1 extends outward from both sides of the first outlet 3 into tapered surfaces 11 with gradually decreasing cross-sectional dimensions. A wedge-shaped surface 12 is provided at one end of the sludge collection chamber 10 near the first outlet 3. Thus, leaves, stones, etc., rotating along the inner wall of the cylinder 1 are collected by the tapered surface 11 and discharged into the first outlet 3, and then guided by the wedge-shaped surface 12 to a deeper part of the sludge collection chamber 10. This ensures sufficient collection space in the sludge collection chamber 10 and prevents leaves, stones, etc., collected in the sludge collection chamber 10 from remaining around the first outlet 3 and being re-raised by airflow, thus affecting the filtration and separation efficiency.

[0034] One end of the cylindrical body 1 is provided with an annular positioning seat 13. The filter structure 4 passes through the positioning seat 13 and is sealed and assembled with the stepped platform on the inner side of the positioning seat 13 by the side flange 14 and the sealing ring, and is fixed by bolts. The encapsulation mesh plate 7 is installed on the filter structure 4 by bolts. A support ring 15 is provided inside the cylindrical body 1. Several support rods 16 radiate from the outer side of the support ring 15. The outer ends of the support rods 16 are positioned on the inner wall of the cylindrical body 1. The support ring 15 is fitted onto the filter structure 4. When installing the filter structure 4, the primary filter layer 5 and the high-efficiency filter layer 6 are first filled into it and the inlet is sealed by the encapsulation mesh plate 7 to fix the filter layers. Then, the inlet end of the filter structure 4 is inserted into the positioning seat 13 and the flange 14 and the sealing ring are sealed and assembled with the positioning seat 13. At the same time, the filter structure 4 passes through the support ring 15 to achieve the inner end support and positioning. Finally, the flange 14 and the positioning seat 13 are positioned by bolts. This makes the disassembly and assembly of filter structure 4 simple, ensuring the high-efficiency filtration performance of the filter device.

[0035] The cylindrical body 1 is provided with positioning guide rails 17 on both sides of the impurity collection box 9. Guide blocks 19 extending from both sides of the impurity collection box 9 slide and engage with guide grooves 18 inside the positioning guide rails 17. A sealing plate 20 slides into the guide grooves 18 and abuts against the end face of the impurity collection box 9, and is positioned on the positioning guide rails 17 by bolts. When assembling the impurity collection box 9 onto the cylindrical body 1, a sealing gasket is first placed on the surface where the impurity collection box 9 and the cylindrical body 1 meet. Then, the guide blocks 19 are slid laterally into the guide grooves 18 to achieve initial positioning of the impurity collection box 9. Finally, the sealing plate 20 is slid into the guide grooves 18 and fixed with bolts. This facilitates the cleaning of the impurity collection box 9, ensuring the high-efficiency filtration performance of the filtration device.

[0036] The working principle of the integrated high-efficiency filtration device for dust collection in a water truck according to this embodiment includes: During use, a negative pressure environment is created inside the cylinder 1 by the fan connected to the second outlet 8, which causes the dust collection structure of the water truck to suck dust from the road surface into the filtration device. The dust-laden airflow enters the cylinder 1 through the inlet 2, and its tangential entry causes large, heavy objects such as leaves and stones to rotate along the inner wall of the cylinder 1 due to centrifugal force and be tangentially guided into the impurity collection box 9 through the first outlet 3 for collection. Through the separation structure of this section, the above-mentioned impurities can be prevented from directly impacting the filter structure 4 and causing damage to its structure, as well as from clogging the filter holes and affecting the filtration efficiency. The dust-laden airflow is sucked into the filter structure 4, and through multiple filtration layers, the airflow is purified and discharged through the second outlet 8, thereby achieving high-efficiency filtration.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
