Description

Technical Field

[0001] The utility model belongs to the technical field of material pumping and filtering of suction and discharge vehicles, and particularly relates to an explosion-proof filter for suction and discharge vehicles. Background Art

[0002] A suction and discharge vehicle (also called a tanker) is a special vehicle dedicated to collecting, transporting, and conveying various dusts and granular materials. The filtration system is an important part of the suction and discharge vehicle, and its design aims to efficiently process and filter materials. However, during the process of pumping materials, situations such as foreign objects, hard blocks blocking the pumping pipe orifice, and material caking and accumulation often occur. In severe cases, potential hazards such as pipe detachment and dust emission may occur. Therefore, it is imperative to study a new filtration device.

[0003] At present, there are also some professional filters in China, but the materials filtered are different from the actual materials at the suction and discharge vehicle site, mainly for precision filtration. In addition, the existing mature filters are complex to install, have high maintenance costs, and are relatively large in size. Moreover, the interfaces of the existing mature filters are basically conventional quick interfaces, which do not match the interface specifications used at the suction and discharge vehicle site.

[0004] In view of the above situation, it is urgent to study a new filter that can effectively screen larger materials and avoid situations such as foreign objects, hard blocks blocking the pumping pipe orifice, and material caking and accumulation during the process of pumping materials by the suction and discharge vehicle. Summary of the Utility Model

[0005] Aiming at the above-mentioned defects existing in the prior art, the purpose of the utility model is to provide an explosion-proof filter for suction and discharge vehicles, which is provided with a barrier filter screen. Using the grid principle, the materials are screened, and at the same time, the materials accumulated in the air source pulverizing bin are pulverized, so as to avoid the barrier filter screen being blocked by material caking in a short time, and effectively improve the operation efficiency of the suction and discharge vehicle.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The utility model provides an explosion-proof filter for suction and discharge vehicles, which includes a fixing frame and a filter body arranged on the fixing frame;

[0008] The filter body includes a first bin and a second bin; a barrier filter screen is arranged at the connection between the first bin and the second bin, and material inlets are arranged at one ends of the first bin and the second bin far away from the barrier filter screen; air valves connected to an air source are respectively arranged at the bottoms of the first bin and the second bin, and upper covers are respectively arranged at the upper parts of the first bin and the second bin.

[0009] Preferably, both the first bin and the second bin are frustum-shaped structures with an open bottom surface, and the material inlets are arranged at the tops of the frustum-shaped structures.

[0010] Preferably, the connection between the first bin and the second bin is a square opening.

[0013] The explosion-proof filter for a suction and discharge vehicle provided by the present utility model has the following beneficial effects:

[0014] 1. The present utility model can effectively screen larger materials, avoiding potential hazards such as material blockage of the suction valve, resulting in pipe detachment and dust emission;

[0015] 2. The present utility model installs a barrier filter screen inside the explosion-proof filter for a suction and discharge vehicle. Using the grille principle, it physically screens larger objects contained in the materials. At the same time, the air source installed in the ventilation pipe at the bottom of the bin continuously blows up and collides with the materials deposited at the bottom, so as to crush the caked materials, thereby increasing the filtration area and avoiding the grille being blocked by material caking in a short time;

[0016] 3. When a large foreign object blocks the present utility model, the upper cover of the feed bin can be easily opened for cleaning. After the operation is completed, the discharge valve at the bottom of the bin can be opened to clean the deposited materials and small foreign objects, which can effectively improve the operation efficiency, reduce the damage rate of the components of the suction and discharge vehicle, and prevent the occurrence of material scattering accidents.

[0022] To better understand the above technical solution of the present utility model, the technical solution of the present utility model will be further described below in conjunction with embodiments.

[0023] In order to avoid situations such as foreign objects and hard lumps clogging the suction and discharge pipe orifice and material caking and sedimentation during the process of sucking and discharging materials by the suction and discharge vehicle, the present utility model installs a barrier filter screen in the filter. Using the grille principle, it physically screens the larger objects contained in the materials. At the same time, the air source connected to the air valve at the bottom of the silo blows up the sedimented materials at the bottom continuously to collide, so as to crush the caked materials, thereby increasing the filtering area and preventing the grille from being clogged by material caking in a short time. After a large foreign object is blocked, the upper cover of the silo can be easily opened for cleaning. After the operation is completed, the discharge valve at the bottom of the silo can be opened to clean up the deposited materials and small foreign objects. Therefore, the present utility model can effectively improve the operation efficiency, reduce the damage rate of the tanker components and prevent the occurrence of material scattering accidents.

[0024] Combined with Figures 1 to 3 As shown, an explosion-proof filter for a suction and discharge vehicle provided by the present utility model includes a fixing frame 1 and a filter body 2 provided on the fixing frame 1. The filter body 2 includes a first silo 21 and a second silo 22; Combined with Figure 3 As shown, a barrier filter screen 27 is provided at the connection between the first silo 21 and the second silo 22, and a material orifice 25 is provided at one end of the first silo 21 and the second silo 22 away from the barrier filter screen 27. Air valves 23 connected to the air source are respectively provided at the bottoms of the first silo 21 and the second silo 22. During the operation, the switch of the air valve 23 can be opened to connect the air source, and the caked materials at the bottom of the silo are continuously blown up and collided to be crushed, removing the internal material sedimentation and blockage, thereby increasing the filtering area and reducing the damage rate of larger materials to components such as the suction valve and the control cylinder. Upper covers 24 are respectively provided on the upper parts of the first silo 21 and the second silo 22. When there are more large materials screened by the filter, only need to open the upper cover 24 of the corresponding silo for cleaning.

[0025] Combined with Figure 3 As shown, the barrier filter screen 27 in the filter body 2 can be replaced according to the actual situation. For example, when transporting materials with larger particles, a barrier filter screen 27 with a larger mesh can be replaced to increase the filtering area and prevent it from being blocked by materials in a short time.

[0026] Combined with Figure 1 、 Figure 2 As shown, the filter body 2 can be set as a symmetric structure, and the material orifice 25, the air valve 23, the upper cover 24, etc. on it can all be symmetrically arranged. Specifically, both the first silo 21 and the second silo 22 are frustum-shaped structures with an open bottom surface, and the material orifice 25 is arranged at the top of the frustum-shaped structure. The connection between the first silo 21 and the second silo 22 is a square opening.

[0027] Combined Figure 2 As shown, discharge valves 26 are respectively provided at the lower parts of the first bin 21 and the second bin 22, and a temporary storage box 3 is provided below the discharge valves 26. After the operation is completed, the discharge valves 26 at the bottom of the bin can be opened to clean up the deposited materials and small foreign objects, and the cleaned materials can be returned to the temporary storage box 3 for temporary storage.
