The water tank plates are connected to each other using the outermost flanges to form the same plane of the water tank of the required size, and the two perpendicular faces of the water tank are formed by connecting the inner flanges. This shape design of the outward bending flanges facilitates the connection between the water tank plates. The water tank plates are welded with plastic electrodes to increase the strength of the water tank and reduce the welding cost. The water tank plates are mass-produced modularly, which is convenient for transportation, time-saving and labor-saving in installation, and has high production efficiency; moreover, the plastic pipe tension bars are used for reinforcement, which also increases the strength of the water tank.

[0004] However, the ventilation duct of the current BDF water tank is connected to the outside. In the rainy season or a dusty environment, it is inevitable that foreign objects such as gravel particles and sewage will enter the BDF water tank through the ventilation duct, which will cause a certain degree of pollution to the water source inside the BDF water tank. Therefore, a BDF water tank is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the existing technology, since the ventilation duct of the current BDF water tank is connected to the outside, in the rainy season or a dusty environment, it is inevitable that foreign objects such as gravel particles and sewage will enter the BDF water tank through the ventilation duct, which will cause a certain degree of pollution to the water source inside the BDF water tank, the present utility model proposes a BDF water tank.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0023] Please refer to Figure 1 - Figure 5 As shown in the figure, a BDF water tank includes side plates 1, a top plate 2, and a bottom plate 3. Mounting components 100 are fixedly connected to the outside of the side plates 1, the top plate 2, and the bottom plate 3. Multiple mounting holes 4 are formed inside the mounting components 100. The side plates 1, the top plate 2, and the bottom plate 3 are assembled and connected by screws 5 passing through the mounting holes 4, and bolts are threadedly connected to the outside of the screws 5. A ventilation pipe 6 is provided at the top end of the top plate 2. The ventilation pipe 6 is fixedly connected to the top plate 2 and penetrates through the top plate 2. A filtering mechanism is provided at the pipe orifice of the ventilation pipe 6. The filtering mechanism includes L-shaped grooves 7. There are two groups of L-shaped grooves 7, and the two groups of L-shaped grooves 7 are formed inside the ventilation pipe 6. A clamping groove 8 is formed at the bottom end of the L-shaped groove 7, and the L-shaped groove 7 communicates with the clamping groove 8. A filtering component 9 is provided inside the ventilation pipe 6, and two clamping blocks 10 are fixedly connected to the outside of the filtering component 9. The clamping blocks 10 are in the clamping grooves 8;

[0024] During operation, the BDF water tank is installed and connected through the mounting components 100 on the outside of multiple side plates 1, the top plate 2, and the bottom plate 3. It is necessary to assemble and connect the side plates 1, the top plate 2, and the bottom plate 3 through the screws 5 passing through the mounting holes 4. The ventilation pipe 6 is used for the internal air of the water tank to communicate with the outside, and the filtering component 9 can be conveniently installed on the ventilation pipe 6, solving the problem that when the ventilation pipe 6 of the current BDF water tank is connected to the outside, in the rainy season or a dusty environment, it is inevitable that foreign objects such as stone particles and sewage will enter the BDF water tank through the ventilation pipe 6, which will cause a certain degree of pollution to the water source inside the BDF water tank, and the process of disassembling and replacing the filtering component 9 is also very convenient.

[0025] Furthermore, the size of the L-shaped groove 7 is the same as that of the clamping groove 8, and the size of the clamping block 10 is adapted to the L-shaped groove 7 and the clamping groove 8;

[0026] During operation, since the installation of the filtering component 9 requires the two clamping blocks 10 on its outside to be inserted into the L-shaped groove 7, and then the filtering component 9 is rotated so that the clamping blocks 10 enter the bottom end of the L-shaped groove 7 and enter the clamping groove 8, the size of the clamping blocks 10 needs to be adapted to the L-shaped groove 7 and the clamping groove 8.

[0027] Furthermore, a connecting seat 11 is fixedly connected inside the ventilation pipe 6, an obstructive block 12 is fixedly connected inside the ventilation pipe 6. A moving seat 13 is provided on one side of the connecting seat 11 close to the filtering component 9. The moving seat 13 is in close contact with the filtering component 9. A moving rod 14 is provided inside the connecting seat 11. One end of the moving rod 14 penetrates through the connecting seat 11 and is fixedly connected to the moving seat 13, and the other end of the moving rod 14 penetrates through the connecting seat 11 and the obstructive block 12 and is fixedly connected to a cylinder 15;

[0028] During operation, when the filter component 9 enters the ventilation pipe 6, the filter component 9 presses against the moving seat 13. At this time, the moving seat 13 drives the long rod and the cylinder 15 to move, and stretches the spring 16 between the cylinder 15 and the blocking block 12 to make it elastic. When the filter component 9 is rotated and not subject to external force, the elastic force of the spring 16 will pop the moving seat 13 forward and pop the filter component 9 outward. At this time, the latch 10 enters the card slot 8, and the filter component 9 cannot move outward continuously to achieve fixation. When it is necessary to replace the filter component 9, only need to press the filter component 9 and rotate it accordingly, so that the latch 10 is pulled out from the L-shaped groove 7 to complete the disassembly.

[0029] Further, a spring 16 is sleeved outside the moving rod 14. One end of the spring 16 is fixedly connected to the cylinder 15, and the other end of the spring 16 is fixedly connected to the blocking block 12;

[0030] During operation, the spring 16 stretches when the moving seat 13 is squeezed, making it elastic, and can press the latch 10 against the card slot 8.

[0031] Further, the size of the moving rod 14 is smaller than the size of the cylinder 15;

[0032] During operation, the fact that the size of the moving rod 14 is smaller than the cylinder 15 allows the moving rod 14 to move normally inside the connecting seat 11 and the blocking block 12, but the cylinder 15 will be blocked by the blocking block 12 to prevent the moving rod 14 from falling off inside the connecting seat 11 and the blocking block 12.

[0033] Further, a positioning groove 17 is provided on one side of the side plate 1, the top plate 2 and the bottom plate 3, and a positioning block 18 is fixedly connected to the other side of the side plate 1, the top plate 2 and the bottom plate 3. The positioning block 18 on one side of the side plate 1, the top plate 2 and the bottom plate 3 is inserted inside the positioning groove 17 on one side of the adjacent side plate 1, the top plate 2 and the bottom plate 3;

[0034] During operation, before installing and connecting the side plate 1, the top plate 2 and the bottom plate 3, only need to insert the positioning block 18 into the positioning groove 17 to complete the positioning, and then install the screw 5 and nut to accurately complete the function of assembling the water tank, solving the problem that the installation of the water tank requires multiple installation holes 4 of the installation component 100 of the side plate 1, the top plate 2 and the bottom plate 3 to be aligned with each other before installing the nut and bolt. If the two side plates 1, the top plate 2 and the bottom plate 3 cannot be positioned first, there will be an installation misalignment problem.

[0035] Working principle: The BDF water tank is installed and connected through the installation components 100 on the outer sides of multiple side plates 1, top plates 2, and bottom plates 3. It is necessary to assemble and connect the side plates 1, top plates 2, and bottom plates 3 through screws 5 passing through the installation holes 4. The ventilation pipe 6 is used for the air inside the water tank to communicate with the outside. Before installing and connecting the side plates 1, top plates 2, and bottom plates 3, only need to insert the positioning block 18 into the positioning groove 17 to complete the positioning, and then install the screws 5 and nuts to accurately complete the function of assembling the water tank. When the filter component 9 needs to be installed, the clamping block 10 on the outside of the filter component 9 is aligned with the L-shaped groove 7, and the filter component 9 is inserted into the ventilation pipe 6. When the filter component 9 enters the ventilation pipe 6, the filter component 9 presses the moving seat 13. At this time, the moving seat 13 drives the long rod and the cylinder 15 to move, and stretches the spring 16 between the cylinder 15 and the blocking block 12 to make it have elasticity. When the filter component 9 is rotated and not affected by external forces, the elastic force of the spring 16 will pop the moving seat 13 forward and pop the filter component 9 outward. At this time, the clamping block 10 enters the clamping groove 8, and the filter component 9 cannot move outward continuously to achieve fixation. When the filter component 9 needs to be replaced, only need to press the filter component 9 and rotate it accordingly, so that the clamping block 10 is pulled out from the L-shaped groove 7 to complete the disassembly.

Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
