Abstract
Description
Technical Field
[0001] The utility model relates to the field of drainage facilities in a painting workshop, and more specifically, to a switchable automatic sealing type floor drain structure. Background Technique
[0002] At the bottom of the paint mist collection device under the dry spray booth currently used in the automotive spraying industry, there is a drainage floor drain. When a fire breaks out, the fire fighting facilities are activated to spray a large amount of fire fighting water for extinguishing the fire. At this time, the dry spray booth drains water through the floor drain at the bottom.
[0003] The existing paint booth drainage floor drain only uses a stainless steel water pipe directly connected to the air duct, and collects and discharges water through the sump in the air duct. When the paint booth equipment is in normal use, some of the air containing the paint mist in the paint booth will not pass through the filter, but directly enter the paint booth air duct through the unsealed floor drain, resulting in pollution of the backend equipment. A large amount of paint adheres to the air duct, fan, and air valve, leading to increased energy consumption, failure of air valve adjustment, and increased emission concentration. Therefore, in the paint mist collection system at the bottom of the dry spray booth, a floor drain structure that can be sealed and does not affect drainage is needed. Content of the Utility Model
[0004] The purpose of the utility model is to provide a switchable automatic sealing type floor drain structure to solve the problems in the above background technique.
[0005] To solve the above technical problems, the utility model is implemented by adopting the following technical solutions:
[0006] A switchable automatic sealing type floor drain structure is arranged at the bottom of the paint mist collection device of the spray booth for draining water, and includes:
[0007] A sump 100, which is arranged at the bottom of the paint mist collection device of the spray booth;
[0008] A drain pipe 200, the top end of which is communicated with the bottom of the sump 100, and the bottom end of the drain pipe 200 extends to the underground air duct;
[0009] A sealing assembly 300, which includes a sealing body 310. The sealing body 310 is arranged at the communication port between the drain pipe 200 and the sump 100, and can seal the communication port. When water is injected into the sump 100, the sealing body 310 can be separated from the communication port under the buoyancy of water.
[0010] Furthermore, a filter screen 400 is covered above the sump 100.
[0011] Furthermore, the filter screen 400 is detachably connected to the sump 100.
[0012] Furthermore, the connection between the water accumulation pit 100 and the bottom of the paint mist collection device of the paint spraying room, and the connection between the drainage pipe 200 and the water accumulation pit 100 are structurally reinforced by reinforcing angle steels 500 .
[0013] Furthermore, the sealing assembly 300 also includes a limit member 320, which is connected to the inside of the water pit 100, and is provided with a slide groove 321 extending in the up and down directions. The sealing body 310 is provided with a sliding shaft 311, and the sliding shaft 311 is freely slidably matched with the slide groove 321 to limit the movement stroke of the sealing body 310 to the extension direction of the slide groove 321.
[0014] Furthermore, the sealing body 310 is a spherical part.
[0015] Furthermore, the sealing body 310 is made of PVC material.
[0016] Compared with the prior art, the beneficial effects of the utility model are:
[0017] The utility model provides an automatically switchable sealed floor drain structure, which provides a sealing body at the connecting port of a drainage pipe and a water pit. When the paint spraying room is working normally, the bottom end of the drainage pipe is connected with the underground air duct, so that the inside of the drainage pipe is in a negative pressure state, and the sealing body is adsorbed on the connecting port of the drainage pipe and the water pit to seal the connecting port, thereby preventing the wind containing paint mist from being discharged through the floor drain and causing pollution to the air duct, air valve, fan, exhaust gas treatment and other equipment at the rear end thereof; when the fire alarm is triggered, the exhaust fan of the paint spraying room stops running, the negative pressure inside the drainage pipe disappears, and the fire-fighting facilities start to spray water at the same time. After the sprayed fire-fighting water enters the water pit, the sealing body will rise upward under the buoyancy of the fire-fighting water and separate from the connecting port of the drainage pipe and the water pit, and the fire-fighting water is drained through the drainage pipe to discharge the water in the water pit, thereby reducing the accumulation of water in the paint mist collecting device of the paint spraying room.
[0018] The utility model provides an automatically switchable sealed floor drain structure, wherein a filter screen is detachably covered above the water accumulation pit, thereby preventing debris from falling into the water accumulation pit and causing blockage, and the filter screen can be disassembled for cleaning when necessary.
[0019] The utility model provides an automatically switchable sealed floor drain structure, which can achieve the dual effects of sealing and drainage, and the sealing state and the drainage state can be automatically switched without manual intervention. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0033] Refer to Figures 1 to 4 , this embodiment provides an automatically switchable sealed floor drain structure, which is arranged at the bottom of the paint mist collection device 600 in the paint spraying booth and is used for draining water inside the paint mist collection device 600 in the paint spraying booth. The floor drain structure includes: a sump 100, a drain pipe 200, a sealing assembly 300 and a filter screen 400.
[0034] The sump 100 is arranged at the bottom of the paint mist collection device 600 in the paint spraying booth and is recessed downward.
[0035] The drain pipe 200 is arranged at the bottom of the sump 100. The top end of the drain pipe 200 is communicated with the bottom of the sump 100, and the bottom end of the drain pipe 200 extends to the underground air duct 700.
[0036] The sealing assembly 300 includes a sealing body 310 and a limiting member 320. The limiting member 320 is composed of two plate members, which are fixedly connected to the bottom of the sump 100 and symmetrically distributed on both sides of the connection port between the drain pipe 200 and the sump 100. A chute 321 extending in the vertical direction is provided on the limiting member 320; the sealing body 310 is arranged at the connection port between the drain pipe 200 and the sump 100 and can seal the connection port. The sealing body 310 is configured as a spherical member made of PVC material. A sliding shaft 311 is provided on the sealing body 310, and the sliding shaft 311 is freely slidably engaged with the chute 321 to limit the movement stroke of the sealing body 310 to the extending direction of the chute 321.
[0037] In the initial state, the sealing body 310 lies at the connection port. When water is injected into the sump 100, the sealing body 310 can be separated from the connection port under the buoyancy of water.
[0038] The filter screen 400 covers the opening of the sump 100. In this embodiment, a wire mesh is used as the filter screen 400, which can prevent sundries from falling and blocking the sump 100. At the same time, the filter screen 400 and the sump 100 can be detachably connected by means of snap connection or the like. When necessary, the filter screen 400 can be disassembled for cleaning work.
[0039] In this embodiment, in order to make the floor drain structure more stable, the connection between the sump 100 and the bottom of the paint mist collection device 600 of the spray booth, and the connection between the drain pipe 200 and the sump 100 are both structurally strengthened by the reinforcing angle steel 500.
[0040] The working principle of the automatically switchable sealed floor drain structure provided in this embodiment:
[0041] Since the bottom end of the drain pipe 200 is connected to the underground air duct 700, when the spray booth is working normally, the exhaust fan of the spray booth works, making the inside of the drain pipe 200 in a negative pressure state, tightly adsorbing the sealing body 310 at the connection port between the drain pipe 200 and the sump 100, sealing the connection port, and preventing the air containing paint mist from being discharged through the floor drain structure, so as to avoid polluting the equipment such as the air duct, air valve, fan, and waste gas treatment at its rear end.
[0042] For example, when a fire breaks out, after the fire alarm, the exhaust fan of the paint spraying booth stops operating, the negative pressure inside the drain pipe 200 disappears, and no longer generates an adsorption force on the sealing body 310. At the same time, the fire-fighting facilities start to spray water. After the sprayed fire-fighting water enters the sump 100, the sealing body 310 rises under the buoyancy of the fire-fighting water and disengages from the communication port between the drain pipe 200 and the sump 100. The fire-fighting water is drained through the drain pipe 200 to discharge the water in the sump 100, reducing the accumulation of water in the paint mist collection device 600 of the paint spraying booth.
