Description

Technical Field

[0001] This application relates to the field of storage tanks, and particularly to a cleaning and discharging device for an EPS storage tank. Background Art

[0002] Expanded polystyrene (EPS) is a lightweight porous polymer, which is manufactured by adding a foaming agent to polystyrene resin and heating it to produce a closed honeycomb structure with bubbles inside. In the storage tank, EPS is likely to adhere to the inner wall of the tank, resulting in the problem of material accumulation. In related technologies, this problem is usually solved by knocking and vibrating the storage tank, but this method has low efficiency, high labor intensity, and incomplete cleaning. Summary of the Invention

[0003] In view of this, this application provides a cleaning and discharging device for an EPS storage tank, which can improve the cleaning efficiency.

[0004] To achieve the above object, this application is realized through the following technical solutions:

[0005] A cleaning and discharging device for an EPS storage tank, characterized in that: it includes a tank body, and two sets of cleaning mechanisms are arranged in the tank body. Each cleaning mechanism includes a barrel brush and a pneumatic structure for driving the barrel brush to rotate;

[0006] The pneumatic structure includes an arc-shaped cylinder body, a ring-shaped rod, a piston and two air path connectors; the arc-shaped cylinder body is coaxially and fixedly arranged in the tank body, the ring-shaped rod is rotatably arranged in the arc-shaped cylinder body, the ring-shaped rod is coaxial with the arc-shaped cylinder body, the piston is fixedly installed on the ring-shaped rod and is located in the arc-shaped cylinder body, the air path connectors are separately installed at both ends of the arc-shaped cylinder body for sealing the inner cavity of the arc-shaped cylinder body. One of the connectors is used for introducing air into the inner cavity of the arc-shaped cylinder body, and the other is used for air intake; the air path connector has an opening for the ring-shaped rod to extend out, and the opening is hermetically arranged with the ring-shaped rod;

[0007] The barrel brush is vertically arranged, and the upper end of the barrel brush is connected to the ring-shaped rod, and the barrel brush fits against the inner wall of the barrel body. When air is introduced into the arc-shaped cylinder body, the piston and the ring-shaped rod can be pushed to rotate together, and the barrel brush can be driven to scrape the inner wall of the tank body; the rotation angle of the ring-shaped rod is 180°, and the arc-shaped cylinder bodies of the two sets of pneumatic structures are arranged in upper and lower layers and are opposite to each other.

[0008] The above-mentioned EPS storage tank cleaning and discharging device of the present application improves the cleaning efficiency by arranging a cleaning mechanism inside the tank. Moreover, since EPS is a flammable material, the cleaning mechanism is pneumatically driven, which has better safety compared to using an electric power drive such as an electric motor. The working process of the cleaning mechanism is as follows: air is introduced into one of the air path connectors, pushing the piston and the annular rod to rotate forward, and driving the barrel brush to rotate together. The barrel brush slides along the inner wall of the tank for cleaning. The maximum rotation angle of the annular rod is 180°, so that the first barrel brush can brush half of the inner wall area of the tank, and the other barrel brush can brush the remaining half area.

[0009] In some embodiments, the pneumatic structure further includes an annular guide rod located below the arc-shaped cylinder body and fixedly arranged inside the tank. The upper end of the barrel brush is hinged to the annular rod, and a sleeve is fixedly arranged at the lower end, and the sleeve is movably sleeved on the annular guide rod. The annular guide rod mainly plays a guiding role and can also be set as a guide rail or other forms according to needs.

[0010] In some embodiments, the outer shape of the arc-shaped cylinder body is a triangle with an upward angle. The arc-shaped cylinder body is set as a triangle mainly to reduce the accumulation of materials on it.

[0011] In some embodiments, the barrel brush includes a brush handle and a soft brush body detachably installed on the brush handle. The connection method between the brush handle and the soft brush body is selected from one of snap connection, bolt connection, magnetic attraction connection, and elastic pressing connection. The barrel brush is set as a split disassembly structure mainly for the convenience of later replacement. The soft brush body is in direct contact with the inner wall of the tank and is a vulnerable part.

[0012] It can be seen from the above technical solutions that the present application has at least the following advantages and positive effects:

[0013] 1. The EPS storage tank cleaning and discharging device of the present application improves the cleaning efficiency by arranging a cleaning mechanism inside the tank. Moreover, since EPS is a flammable material, the cleaning mechanism is pneumatically driven, which has better safety compared to using an electric power drive such as an electric motor. The working process of the cleaning mechanism is as follows: air is introduced into one of the air path connectors, pushing the piston and the annular rod to rotate forward, and driving the barrel brush to rotate together. The barrel brush slides along the inner wall of the tank for cleaning. The maximum rotation angle of the annular rod is 180°, so that the first barrel brush can brush half of the inner wall area of the tank, and the other barrel brush can brush the remaining half area.
