[0002] A filter-washer-dryer is a device that integrates filtering, washing, and drying functions and is widely used in the chemical, pharmaceutical, and food industries. This machine can effectively process various solid-liquid mixtures to achieve separation and purification of materials.

[0003] Existing filtering, washing and drying machines, for example, Chinese patent literature discloses a multi-layer filtering filter [patent number: 202010831172.9; application publication number: CN111991883A], which includes a filter cartridge and a bottom cover, the filter cartridge is detachably connected to the top of the bottom cover, the bottom cover is provided with a first filtering structure, the bottom of the bottom cover has a first liquid outlet, the first filtering structure includes a filter plate, the center of the bottom cover is provided with a second liquid outlet, the outer edge of the bottom cover is provided with a raised annular first support ring, the inner edge of the bottom cover is provided with a raised annular second support ring, the filter plate is annular, and the outer edge of the filter plate abuts on the first support ring, the inner edge of the filter plate abuts on the second support ring, the filter plate, the bottom cover, the first support ring and the second support ring form a filter chamber, the first liquid outlet is connected to the filter chamber, and the second liquid outlet is connected to the cavity in the filter cartridge.

[0004] In the first filter structure of this filter structure, liquid passes through the filter plate and enters the filter cavity before being discharged from the first liquid outlet. After filtration is complete, waste liquid can be discharged from the second liquid outlet to prevent clogging of the filter plate. However, in this first filter structure, after the waste liquid is discharged from the second liquid outlet, some solid residue still remains in the first filter structure, which needs to be dried through the filter to form a filter cake. However, because the drying structure is far away from the solid residue, drying takes a long time and has low drying efficiency. Summary of the Invention

[0005] The purpose of the utility model is to solve the above problems existing in the prior art and propose a chassis device for a filter washing and drying machine. The technical problem solved is how to quickly dry the solid residue on the chassis device to form a filter cake.

[0006] The objectives of the present utility model can be achieved through the following technical solutions: a chassis device of a filtering washing and drying machine, comprising a bottom plate with a liquid outlet and a filter assembly arranged on the bottom plate, a filter space being provided between the bottom plate and the filter assembly, and characterized in that the bottom plate is provided with a plurality of heating blocks protruding upward and arranged at intervals, the spaces left between all the heating blocks jointly forming a filtrate cavity, the filtrate cavity being connected to the liquid outlet, all the heating blocks and the filtrate cavity being located in the filter space, and the filter assembly resting against the heating blocks.

[0007] During operation, the filtrate after the solid-liquid mixture is filtered through the filter assembly enters the filtrate chamber, and then the filtrate is discharged through the liquid outlet. The solid residue in the solid-liquid mixture is left on the filter assembly, and the heating block is heated. Since the heating block is placed close to the solid residue, the heating block can quickly dry the solid residue to form a filter cake. The filter assembly rests on the heating block, firstly, so that the heating block can better dry the solid residue and quickly form a filter cake, and secondly, the heating block can support the filter assembly, preventing the filter assembly from deformation and damage.

[0008] In the aforementioned chassis assembly of the filter-washing-dryer, the bottom plate has a water inlet and outlet, and all the heating blocks have heating cavities. These cavities are interconnected to form a heating channel, one end of which is connected to the water inlet and the other end to the water outlet. This structure enables the heating cavities in the heating blocks to form a circulating heating channel, providing the heating blocks with continuous heating, allowing solid residue on the chassis assembly to be quickly dried to form a filter cake.

[0009] In the chassis assembly of the aforementioned filter-washing-dryer, a heating pipe is provided between two adjacent heating blocks. The top surface of the heating pipe is flush with the top surface of the heating block, and the heating pipe connects the two adjacent heating chambers. The heating pipe serves to connect the heating blocks and also supports the filter assembly.

[0010] In the chassis assembly of the aforementioned filter-washing and drying machine, the bottom plate also has an air inlet. A first annular backflush pipe is provided along the circumferential edge of the filtration space. A plurality of second backflush pipes with backflush holes are provided in the filtrate chamber. The first backflush pipe is connected to the air inlet, and one end of each of the second backflush pipes is connected to the first backflush pipe. After filtration is completed, nitrogen is introduced into the first backflush pipe through the air inlet, then into the second backflush pipe, and finally blown out through the backflush holes to backwash the filtrate chamber and the heating block, thereby keeping the filtration space clean.

[0011] In the chassis device of the above-mentioned filtering, washing and drying machine, the filtering component includes a filtering ring, a filtering hole plate, a filtering net and a first sealing ring. The filtering hole plate is fixedly connected in the filtering ring, the filtering net is fixedly connected to the filtering hole plate, and the first sealing ring is arranged on the circumferential outer side of the filtering ring.

[0012] In the chassis device of the above-mentioned filtering, washing and drying machine, the bottom of the filtering hole plate has a plurality of first buckles, and the filtrate cavity has a plurality of second buckles. The first buckles and the second buckles are arranged in one-to-one correspondence. When the filtering component is placed on the bottom plate and rotated, the first buckles and the second buckles can be engaged with each other, so that the bottom plate and the filtering component are positioned. This structure makes the assembly of the filtering component and the bottom plate convenient.

[0013] In the chassis device of the above-mentioned filtering, washing and drying machine, a plurality of lifting holes are arranged at intervals on the circumferential outer side of the filtering ring. The first buckle is in a U shape, and the second buckle is in an L shape. During assembly, the filtering component is lifted through the lifting holes, the filtering component is placed on the bottom plate, and then the filtering component is rotated so that the second buckle is inserted into the first buckle, and the filtering component and the bottom plate can be positioned, making the assembly of the filtering component and the bottom plate convenient.

[0014] In the chassis device of the above-mentioned filtering, washing and drying machine, the filtering hole plate has a plurality of large filtering holes and a plurality of small filtering holes. The number of small filtering holes is much larger than the number of large filtering holes. The filtering hole plate and the filtering net are fixedly connected by welding at the large filtering holes. Both the large filtering holes and the small filtering holes play a role in filtering. The setting of the large filtering holes makes the welding of the filtering hole plate and the filtering net convenient; for example, the number of small filtering holes is 100 and the number of large filtering holes is 2.

[0015] In the chassis device of the above-mentioned filtering, washing and drying machine, a second sealing ring is provided between the filtering ring and the bottom plate.

[0016] In the chassis device of the above-mentioned filtering, washing and drying machine, the liquid outlet is located at the center of the bottom plate.

[0017] Compared with the prior art, the chassis device of the filtering, washing and drying machine provided by the present utility model has the following advantages:

[0018] 1. A heating block is arranged in the chassis device. By heating the heating block, the solid residue on the chassis device can be quickly dried to form a filter cake.

[0019] 2. The heating block of the chassis device plays a role in supporting the filtering component, so that the filtering component will not deform or be damaged. Description of the Drawings
