Description
Technical Field
[0001] This utility model belongs to the field of groove cover technology, specifically relating to an inward-opening, corrosion-resistant, and explosion-proof groove cover. Background Technology
[0002] Steam degreasing primarily utilizes the vapor of organic solvents to dissolve oil stains on the surface of parts, ensuring the surface cleanliness of mechanical production components meets production standards. Typically, steam degreasing equipment requires heating the organic solvent. When oily mechanical parts are placed in the degreasing area, the organic solvent vapor condenses on the part's surface. The organic solvent and oil stains dissolve together and then drip into a solvent tank at the bottom of the equipment, effectively removing the oil stains.
[0003] In existing technologies, components requiring degreasing are typically placed into the steam degreasing equipment from the top. Since steam degreasing equipment generally operates in high-temperature environments and commonly uses volatile organic solvents such as trichloroethylene and perchloroethylene, if the equipment is not properly sealed, the organic solvents used in steam degreasing, which are mostly flammable and explosive, will release large amounts of vapors into the surrounding environment, endangering the health of operators and polluting the atmosphere. Furthermore, the organic solvents used in steam degreasing are mostly flammable and explosive, and the complex environment of production workshops, including the use of electrical equipment and metal collisions, can generate sparks. If the entire degreasing equipment is not effectively sealed, accidental explosions may occur, seriously endangering equipment and personnel safety. Finally, the complex environment of production workshops may contain foreign objects, dust, metal debris, and other contaminants. If these enter the steam degreasing tank, they will contaminate the organic solvents and the components requiring degreasing, resulting in incomplete degreasing and cleaning.
[0004] In addition, in order to meet the needs of large-scale production, steam degreasing equipment is also developing towards larger sizes, so as to clean more parts at once and improve production efficiency. However, larger equipment requires more space, which will increase the cost of factory construction. Utility Model Content

[0011] Furthermore, the drive unit includes a reducer, a drive shaft, and a main shaft. One end of the drive shaft is used to mount a wheel or handle, and the other end of the drive shaft is connected to the power input end of the reducer to drive the reducer to operate.

Correspondingly, the groove cover plate is provided with transmission devices on both the left and right sides. The drive device includes two main shafts, which drive the transmission devices on the left and right sides respectively.
[0014] Furthermore, there are two tank cover plates, symmetrically arranged on the top of the steam degreasing cleaning tank, namely the front tank cover plate and the rear tank cover plate.

[0015] The beneficial effects are:
[0016] By installing linear and arc-shaped slide rails on the side plate of the tank cover, and setting first, second, and third pulleys on the tank cover, and driving it through a transmission device, the tank cover can slide to a vertical position when opened, located inside the side plate of the tank cover. This achieves an inward opening design for the tank cover, eliminating the need for outward opening equipment and saving space. In addition, by setting a sliding opening tank cover, the steam oil removal equipment can be effectively sealed, preventing foreign objects from falling into the steam oil removal equipment and avoiding the escape of toxic, harmful, and explosive organic solvent gases. This solves the technical problems of low production safety, environmental pollution, and incomplete oil removal caused by steam oil removal equipment.
[0017] By installing side plates with linear and arc-shaped slide rails on both the left and right sides of the trough cover, the trough cover can be opened and closed synchronously from both sides, which helps to smoothly open and close large trough cover equipment.
[0018] By setting two tank cover plates, it can be opened from both sides, avoiding the large volume of the top tank cover plate of the large steam degreasing cleaning equipment, which is difficult to drive and can be retracted to the inside of the tank cover side plate when opened.
