Description

Technical Field

[0001] The utility model belongs to the technical field of tank trucks, and in particular relates to a detachable flexible closed compartment structure. Background Art

[0002] When tank trucks are transporting powdery and granular materials (such as flour), customers often require materials of different qualities at the same time, and the demand for each quality of material is relatively small. In order to improve the economic benefits of vehicle transportation, a tank truck is often required to transport materials of different qualities at the same time and unload them into different storage bins. Therefore, a closed compartment structure is required inside the tank truck to divide the interior of the tank truck into more than two independent compartments to pack materials of different qualities.

[0003] Existing closed compartment structures such as Figure 5 and Figure 6 As shown, a whole piece of steel plate is used to completely seal the two adjacent compartments in the tank body. Since the tank trucks transporting powders and particles use pneumatic unloading when unloading, the pressure in the tank is generally around 0.2MPa. Therefore, a vent pipe needs to be arranged on the top of the tank body to connect the two adjacent compartments. The vent pipe is made of steel pipe and is in a "U" shape. The two ports are welded and connected to the two compartments respectively to maintain the air pressure balance of each compartment.

[0004] There are the following problems when using a whole piece of steel plate to make a compartment structure:

[0005] 1) Significantly increase the weight of the tank truck

[0006] The partition panels are usually made of 4-5mm steel plates. Tank trucks usually have 3-6 compartments, which means 2-5 partition panels are needed. The overall weight of the tank truck increases, and the economic benefits decrease.

[0007] 2) The partition panel is made of a whole piece of steel plate and cannot be disassembled

[0008] When customers need to load only one quality of material in a tank truck due to business changes, the entire partition cannot be disassembled as a whole, but can only be cut into small pieces and taken out from the manhole on the top of the tank truck;

[0009] 3) The ventilation pipe on the top of the tank connects two adjacent independent chambers. Therefore, when the tank is inflated and unloaded, a small amount of material will pass through the ventilation pipe from the previous chamber into the next chamber along the air flow, posing a risk of mixed contamination of materials of different qualities. Utility Model Content

[0010] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a detachable flexible closed partition structure for solving the technical problems that the partition panels of the existing tank trucks are too heavy and cannot be disassembled and reused repeatedly, and the ventilation pipes of the tank trucks are connected in series with multiple chambers, which is easy to mix materials.

[0011] The utility model solves the above technical problems with the following technical solutions: a detachable flexible closed compartment structure, comprising:

[0012] A tank body, wherein the tank body is divided into a plurality of chambers;

[0013] A plurality of partition plates, each of which is disposed between two adjacent chambers, and each of which comprises a frame plate and a breathable cloth, wherein the breathable cloth is covered on the hollowed-out portion of the frame plate, and the breathable cloth is only permeable to air but not to powdered materials;

[0014] A ventilation main pipe is arranged above the tank body, and a plurality of ventilation branch pipes are also arranged on the ventilation main pipe, and the plurality of ventilation branch pipes are respectively connected with a plurality of the chambers in a one-to-one correspondence.

[0015] The partition board in the utility model is no longer a whole steel plate, but is composed of a hollow frame board and a hollow breathable cloth covered thereon. This not only reduces the weight of the partition board and improves the transportation economy, but also allows the breathable cloth to be removed when the warehouse needs to be cleared, and the warehouse can be restored. In addition, the parallel ventilation pipes can avoid mixing of materials.

[0016] Furthermore: the hollowing includes a single hole or a plurality of holes.

[0017] The beneficial effect of adopting this step is that the partition plate can be hollowed out with a single hole or multiple holes according to the position and area of ​​the tank body where it is located.

[0018] Furthermore: the outer layer of the breathable cloth is also provided with a pressing plate, and the pressing plate is fixedly connected to the frame plate through a bolt assembly.

[0019] The beneficial effect of adopting this step is that the breathable cloth can be repeatedly disassembled and installed through the pressing plate.

[0020] Furthermore: a sealing rubber pad is sewn around the periphery of the breathable cloth.

[0021] The beneficial effect of adopting this step: the sealing pad can prevent the material from seeping out from between the breathable cloth and the pressing plate, avoiding mixing of materials.

[0022] The beneficial effects of the utility model are:

[0023] 1. Light weight, with flexible compartment structure, the vehicle is light in weight, which means more cargo can be carried or fuel consumption can be reduced, which can significantly improve economic benefits;

[0024] 2. Low cost. Generally speaking, tank trucks that require closed partitions with independent compartments are used to transport flour or other relatively high-end chemical materials. The tank body is made of stainless steel. The flexible closed partition structure is used. The cost of this application is lower than that of closed partitions made of a whole piece of steel plate. The more compartments there are, the more significant the benefits.

[0025] 3. Easy to assemble and disassemble. The flexible closed compartment structure is to assemble and connect the breathable cloth with the inner frame plate of the tank truck with bolt assemblies. This structure can be assembled and disassembled. When the customer operates for a period of time and no longer needs an independent compartment due to business adjustments, the flexible compartment structure can be dismantled to quickly restore the tank truck to a state of open storage. However, in the closed compartment structure of the prior art, in order to restore the tank truck to a state of open storage, it is necessary to use fire to cut off the steel plate, and then grind and clean it. The whole process is time-consuming, labor-intensive and costly.

[0026] 4. The flexible compartment structure itself has a certain ventilation function, which can more effectively maintain the air pressure balance of each independent compartment, making it safer to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Example

[0044] Before describing the technical solution of this application in detail, Figure 5 and Figure 6 The tank compartment structure in the prior art is described. In the prior art, the tank 1 has multiple compartments, which are separated by a compartment partition plate 2'. When the tank 1 needs to be ventilated, the compartment partition plate 2' needs to be cut, polished, cleaned, etc. In addition, the air intake pipe 32 of the tank 1 in the prior art is to take in air from the compartment at one end, and the adjacent compartments are connected by a U-shaped vent pipe 33, so that the gas flow paths of the multiple compartments form a series structure.

[0045] like Figure 1 to Figure 4 As shown, the utility model provides a detachable flexible closed compartment structure, comprising:

[0046] A tank body 1, wherein the tank body 1 is divided into a plurality of chambers;
