[0002] Filtration, washing and drying equipment is a device that completes the processes of filtration, washing and drying of materials inside a tank to prevent the materials from being contaminated by foreign objects or microorganisms.

[0003] Traditional filter washing and drying machine chassis are usually designed with a sealed structure to improve the sealing effect. However, in actual operation, due to the characteristics of the materials and long-term operation of the equipment, the sealing performance may decline, leading to leakage problems and causing environmental pollution and safety hazards. The existing technology lacks effective online leakage detection and alarm functions, making it impossible to detect and deal with leakage problems in a timely manner, which limits the safety and reliability of filter washing and drying equipment.

Detailed Implementation

[0028] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0029] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0030] The directional and positional terms used in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are merely for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0031] like Figures 1 to 3 As shown in the figure, an online leak detection structure for the chassis of a filter washing and drying machine is provided in an embodiment of the present invention. It includes a vessel body 1 and a chassis assembly embedded in the bottom of the vessel body 1. A first sealing assembly is provided between the inner circumference of the vessel body 1 and the upper outer circumference of the chassis assembly.

[0032] A first gap cavity 101 is provided between the inner circumference of the vessel body 1 and the outer circumference of the chassis assembly. The lower outer circumference of the first gap cavity 101 is closed. A first through hole 201 is provided at the position corresponding to the bottom of the inner circumference of the first gap cavity 101 on the chassis assembly. One end of the first through hole 201 communicates with the first gap cavity 101, and the other end is connected to a detection pipe 4. A liquid detection assembly is connected to the lower end of the detection pipe 4.

[0033] It also includes a PLC control unit that is electrically connected to the liquid detection component. When the liquid detection component detects that liquid has entered the detection pipe 4, it sends an electrical signal to the PLC control unit.

[0034] With this design, when leaking liquid leaks from the first sealing component, it first flows into the first gap cavity and then enters the detection pipe through the first through hole. The liquid detection component will detect the leaking liquid, thereby reminding the staff to take appropriate measures in a timely manner, which improves the safety and reliability of the filter washing and drying equipment.

[0035] A control valve 6 is connected at a position in the middle of the detection pipeline 4 to control its opening and closing. After receiving a leakage signal from the liquid detection component, the PLC control unit controls the control valve 6 to disconnect the connection of the detection pipeline 4.

[0036] With this setting, when the liquid detection component does not detect a leak, the control valve is normally open, allowing liquid to enter the liquid detection component. When the liquid detection component detects a leak, the control valve closes, thus preventing the leaked liquid from being exposed to the air, polluting the environment, and harming operators.

[0037] The liquid detection assembly includes a collection bottle 51 and a sensor 52. The collection bottle 51 is connected to the lower end of the detection pipe 4, and the sensor 52 is connected to the lower end of the collection bottle 51 to sense whether liquid has entered the collection bottle 51.

[0038] The sensor can detect whether liquid has entered the collection bottle by detecting the liquid or by detecting whether the collection bottle has undergone mass change. Specifically, it can be a liquid level sensor, humidity sensor, pressure sensor or weight sensor.

[0039] The chassis assembly includes a base 2 and a filter plate bracket 3 detachably connected to the base 2. The first sealing assembly is located between the upper outer periphery of the filter plate bracket 3 and the inner periphery of the vessel body 1.

[0040] The base 2 includes a first seat cylinder portion 21 and a second connecting ring portion 22 connected to the outer periphery of the lower end of the first seat cylinder portion 21.

[0041] There is a gap between the outer periphery of the first seat cylinder portion 21 and the inner periphery of the vessel body 1.

[0042] A third sealing assembly is connected between the upper end of the second connecting ring 22 and the bottom of the vessel body 1, and the third sealing assembly forms a seal on the outer periphery of the bottom of the first gap cavity 101.

[0043] This design improves the ease of assembly and disassembly of the split chassis components.

[0044] A second sealing assembly is provided between the base 2 and the filter plate bracket 3.

[0045] With this setup, if leakage fluid leaks from the second sealing assembly, the leakage fluid will also flow into the first gap cavity, and the liquid detection assembly can simultaneously detect leaks at the sealing positions of the first and second sealing assemblies.

[0046] The base 2 has a first positioning ring groove 23 on its upper outer periphery, and the filter plate bracket 3 has a second positioning groove 31 at its lower end that is adapted to the shape of the first positioning ring groove 23 and forms an abutment fit with it.

[0047] The second sealing assembly includes a second sealing groove 24 disposed on the upper end of the base 2, and a second sealing ring 25 is installed in the second sealing groove 24 to form a seal between the upper end surface of the base 2 and the bottom of the second positioning groove 31.

[0048] This design improves the ease and stability of assembling the filter plate bracket and the base.

[0049] The filter plate bracket 3 has a first frustum 34 on its upper outer periphery, which is smaller at the top and larger at the bottom. The inner cavity of the vessel body 1 is correspondingly provided with a second frustum 11 that is adapted to the shape of the first frustum 34 and forms a close fit.

[0050] The filter plate bracket 3 is provided with a first sealing groove 32 on its outer periphery, and a first sealing ring 33 is installed in the first sealing groove 32 to form a sealing fit between the first frustum surface 34 and the second frustum surface 11.

[0051] This design improves the sealing effect between the filter plate support and the inner cavity of the vessel.

[0052] The third sealing assembly includes a third sealing groove 221 disposed on the upper end of the second connecting ring 22, and a third sealing ring 222 is installed in the third sealing groove 221 to form a seal between the upper end surface of the second connecting ring 22 and the bottom surface of the vessel body 1.

[0053] The first through hole 201 slopes downward from one end of the first gap cavity 101 to one end of the detection pipe 4.

[0054] This design prevents leaked fluid from accumulating in the first through hole.

[0055] The chassis assembly is connected to a quick-installation interface 26 on its inner periphery. The quick-installation interface 26 has a second through hole 27 that communicates with the first through hole 201 and the detection pipe 4. The end of the quick-installation interface 26 away from the first through hole 201 is connected to the detection pipe 4 with a clamp.

[0056] This setup improves the ease of disassembling and assembling inspection pipes.

[0057] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
