Description

Technical Field

[0001] The invention relates to the technical fields of food production workshops, pharmaceutical plants, chemical plants and clean engineering, and more specifically to a clean floor drain. Background Art

[0002] The floor drain is an important interface between the drainage pipe system and the workshop floor. As an important component of the drainage system in the workshop, its performance directly affects the quality of the workshop air and is very important for odor control in the workshop.

[0003] However, the existing clean floor drains have the following problems: 1. It is not convenient to clean, because there are many welds in the cover plate welding, these welds are easy to breed bacteria, making it impossible to clean; 2. The sealing is not good. Traditional sealing rings are divided into "sealing ring and water seal upper part fully wrapped type" and "sealing ring and water seal upper part separation type", but the sealing ring of "sealing ring and water seal upper part fully wrapped type" is difficult to disassemble, easy to breed bacteria, and inconvenient to clean, while the sealing ring of "sealing ring and water seal upper part separation type" is columnar, and the lower part of the water seal is also columnar. It is difficult to install, and because the sealing ring is separated from the upper part of the water seal, the sealing is poor, and air and water leakage is easy to occur; 3. It does not have anti-freeze function. When the floor drain is used in a low-temperature workshop environment, it is easy for ice to form inside the floor drain and freeze. If it is not thawed in time, it will cause technical problems that affect the normal drainage of the floor drain; in addition, the traditional cover plate welding has many welds, which are easy to breed bacteria and cannot be cleaned; for traditional floor drains, the sealing ring and the upper part of the water seal are fully enclosed. The floor drain is not convenient to disassemble and is easy to breed bacteria. The separated type is prone to water and air leakage.

[0004] The present invention has the following advantages: 1. It is easy to clean and can prevent bacteria from breeding; 2. It improves sealing and is easy to disassemble; 3. The floor drain has an anti-freeze function. When the floor drain is used in a low-temperature workshop environment, it is not easy for ice to form inside the floor drain and be frozen. It can be thawed in time, ensuring normal sewage discharge from the floor drain. Summary of the invention

[0020] Beneficial effects:

[0021] 1. This clean floor drain is provided with an antifreeze component. When the temperature inside and outside the body is too low, the low temperature is first transmitted to the inside through the shell of the antifreeze component, so that the temperature control component of the antifreeze component is deformed in turn by the cold, and the discharge component of the antifreeze component is triggered successively to output the de-icing material, which comes into contact with another type of de-icing material in the temperature control component to generate heat, and the hot temperature is then transmitted back to the body through the shell; in this way, under the continuous and joint action of multiple antifreeze components, ice can be prevented from freezing inside the body;

[0022] 2. This clean floor drain is provided with a temperature control component. When the temperature inside and outside the body is normal, the outer surface of the left bottom end of the lower rotating plate of the temperature control component is statically attached to the lower end surface of the left inner wall of the shell; the lower air bag of the temperature control component is in a naturally expanded and undeformed state, and the clean water therein is in a liquid state; but when the temperature inside and outside the body is too low, this state will be gradually broken, that is, as mentioned above, when the low temperature is transmitted to the shell, the clean water in the lower air bag will first be cooled and frozen from liquid to solid, and its own volume will increase. Under the joint limiting action of the shell and the body, the top of the lower air bag will expand and stretch upward; then the lower rotating plate will be driven to rotate upward clockwise, so that the push plate and the pointed cone on it will rotate synchronously, so as to trigger the discharging component to export the de-iced material in the subsequent process, and the material will fall into the left and right grooves of the temperature control component one after another, and heat up after contacting with the brine in the two grooves; in this way, the deformation can be controlled according to the temperature, which is convenient for anti-freezing;

[0023] 3. This clean floor drain is provided with a discharge assembly. When the temperature inside and outside the body is normal, the film of the discharge assembly is in the maximum tension state, and there is a distance between the top tip of the pointed cone of the temperature control assembly and the film; the upper air bag of the discharge assembly is in a natural expansion and non-deformation state, and the quicklime powder inside it does not overflow; the left outer surface of the upper rotating plate of the discharge assembly is statically attached to the right to lower end outer surface of the upper air bag; the sealing strip of the discharge assembly tightly seals the outlet of the upper air bag; but when the temperature inside and outside the body is too low, this state will be gradually broken, that is, as mentioned above, the lower rotating plate, the push rod and the push rod will be opened. When the plate and the pointed cone rotate upward clockwise synchronously, the top tip of the pointed cone will eventually come into contact with the film and continue to push it upward to puncture it, so that the quicklime powder on the film will fall into the left and right grooves of the temperature control component respectively, and come into contact with the brine in the two grooves to generate heat; the heat is transmitted upward to the surface of the upper air bag, causing it to expand due to the heat, pushing the upper rotating plate to rotate counterclockwise to the right, so as to pull the sealing strip away from the outlet of the upper air bag, and release the quicklime powder in the upper air bag to the outside to supplement and continue heating; in this way, it is possible to export the de-icing material at a low temperature, which is convenient for anti-freezing;

[0024] 4. This type of clean floor drain is easy to clean by bending the corners of the clean cover plate; the clean cover plate is fully welded to remove dead corners such as gaps, which is not easy to breed bacteria;

[0025] 5. This type of clean floor drain has a sealing ring with a wide top and narrow bottom structure, which is convenient for disassembly. At the same time, during the disassembly and cleaning process, it will not deform even if repeated many times. The lower part of the sealing ring adopts a U-shaped structure, which cooperates with the convex and concave structure of the upper part of the water seal, which has a certain sealing effect. When water enters the gap, the sealing effect is better through its own pressure and water pressure.

[0026] 6. In summary, this kind of clean floor drain, through the joint cooperation of antifreeze components, temperature control components, discharge components, clean cover plates, sealing rings and water seals, has the following advantages: 1. Easy to clean and prevent bacterial growth; 2. Improve sealing and facilitate disassembly; 3. The floor drain has an antifreeze function. When the floor drain is used in a low-temperature workshop environment, it is not easy for ice to form in the floor drain and be frozen. It can be thawed in time to ensure normal sewage discharge from the floor drain. BRIEF DESCRIPTION OF THE DRAWINGS
