The electric control application cabinet can reduce the amount of water vapor entering the electric control application cabinet during heat dissipation.

The utility model discloses a modularization water pump body subassembly of quick detachable, belongs to modularization water pump body subassembly technical field, including base and pump casing, the pump casing sets up at the top of base, the lower surface fixed mounting of pump casing has two plug -in boards, the upper surface of base is seted up with two insertion slot, the plug -in board is inserted in the inner wall of the insertion slot at the corresponding position, the inside rotatory mounting of base has two -way screw rod, one end of two -way screw rod extends out base and fixed mounting has the rotating plate, through setting plug -in board cooperation card board use, after the plug -in board is inserted into the insertion slot, utilizes the rotation of two -way screw rod and drives the threaded plate movement, and under the hinging effect of hinged arm, drives the push -plate and drives the card board movement and is inserted into the card slot, realizes the locking of plug -in board, and then completes the assembly locking of pump casing and base, and the assembly mode does not use bolt, and the assembly structure is simple, and convenient operation avoids the bolt loosening and bolt rust problem that bolt assembly can easily appear.

The utility model discloses a pollution gas treatment device in a titanium dioxide production process, which comprises a treatment tank, a dust vibration mechanism is arranged at the top of the treatment tank, the surface of the dust vibration mechanism is respectively in transmission connection with a vibration frame and a dust guide shaft, the inner wall of the vibration frame is rotationally connected with an outer rotating cylinder, and the inner wall of the outer rotating cylinder is rotationally connected with an inner vibration shaft; the inner vibrating shaft and the outer rotating cylinder are both driven by a dust guide shaft, a dirt inlet assembly matched with the dust guide shaft is installed at the axis position of the inner vibrating shaft, and a filter element is fixedly installed on the circumferential side face of the inner vibrating shaft through a three-jaw connecting frame. When the device is used, the adhesion rate of dust on the dust filtering mechanism can be effectively reduced through self-vibration and self-rotation of the dust filtering mechanism, and self-dust-shaking and self-dust-removing of the dust filtering mechanism are achieved through self-vibration and self-rotation of the dust filtering mechanism.

The utility model discloses a combined oil screen dust filter, which belongs to the field of oil screen dust filters and comprises an oil screen dust filter shell, an oil screen structure is fixedly mounted in the oil screen dust filter shell, and a sealing frame is fixedly mounted in the oil screen dust filter shell and on the front side of the oil screen structure. Four mounting base plates are symmetrically and fixedly mounted on the outer wall of the oil screen dust filter shell in pairs, a winding structure is rotationally mounted on the two mounting base plates on the same side, the winding structure is composed of a winding rod, a limiting baffle and a rotating crank, the limiting baffle is fixedly mounted at the lower end of the winding rod, the rotating crank is fixedly mounted at the upper end of the winding rod, and the limiting baffle is fixedly mounted at the lower end of the winding rod. According to the oil screen dust filter, the fiber filter cloth is arranged on the front side of the oil screen structure and can pre-filter polluted gas entering the oil screen dust filter shell, so that large particles in polluted air are blocked, the large particles are effectively prevented from entering the oil screen structure, finally the burden of the oil screen structure can be reduced, and the service life of the oil screen dust filter is prolonged. And the dust filtering effect of the oil screen dust filter is improved.

The utility model relates to the technical field of coke oven flue gas treatment, and discloses a coke oven ascension pipe flue gas dust collection device which comprises a treatment box, a gas inlet pipe is fixedly connected to the left side of the treatment box, a gas outlet pipe is fixedly connected to the upper portion of the treatment box, and a drain valve is fixedly installed on the front face of the treatment box. A first dust filtering plate and a second dust filtering plate are fixedly connected to the inner wall of the treatment box, the second dust filtering plate is arranged on the right side of the first dust filtering plate, a cleaning mechanism is arranged on the left side of the first dust filtering plate, and a spraying mechanism is arranged between the first dust filtering plate and the second dust filtering plate. According to the flue gas dust collecting device for the coke oven ascension pipe, the cleaning mechanism is arranged, dust is prevented from blocking the first dust filtering plate, the dust filtering efficiency is improved, meanwhile, the dust filtering effect is improved, the spraying mechanism is arranged, water mist is sprayed out to adsorb and settle residual solid particles in flue gas, meanwhile, the spraying range is widened, the flue gas is further purified, and the dust collecting effect is improved. And the treatment effect is improved.
