Technical Field

[0001] The utility model relates to the technical field of filter device installation, in particular to a wastewater filter cartridge installation frame. Background Art

[0002] Wastewater treatment is the process of treating wastewater using physical, chemical and biological methods to purify the wastewater, reduce pollution, and achieve wastewater recovery and reuse.

[0003] With the continuous development of ultrafiltration membrane technology, various ultrafiltration membrane wastewater treatment devices have emerged, among which submerged ultrafiltration membrane equipment is one of them. Its application form is mainly to place the ultrafiltration membrane group directly in the wastewater filtration tank, and form filtration through the suction action of the pump. Submerged ultrafiltration has the characteristics of small footprint, strong resistance to shock loads and pollution, and has been widely used in the water treatment industry.

[0004] When placing the submerged ultrafiltration membrane group into the wastewater filtration pool, the components cannot be reinforced, which results in poor stability during the installation of filtration equipment of different sizes, or cumbersome work during the installation and disassembly process, which is not conducive to batch installation and disassembly, and is not conducive to maintenance work. Utility Model Content

[0005] The purpose of the utility model is to provide a wastewater filter cartridge mounting frame, which is used to overcome the above-mentioned defects in the prior art.

[0006] According to the utility model, a wastewater filter cartridge mounting bracket comprises a mounting opening, the mounting opening is connected with a filter cartridge, the mounting opening and the outer periphery of the filter cartridge are connected with two groups of rear clamping plates and front clamping plates distributed front and back, elastic pads are arranged on the inner peripheries of the rear clamping plates and the front clamping plates, the rear clamping plates and the front clamping plates are distributed up and down, and the rear clamping plates and the front clamping plates arranged up and down are connected with fixing rods for fixing connection, guide slides are fixedly arranged at the left and right ends of the rear clamping plate, and two left and right symmetrical fixing brackets are fixedly arranged on the rear end surface of the front clamping plate, and the guide slides extend backwards and penetrate through the fixing bracket, A thrust spring is connected between the fixed frame and the guide slide frame, and two left-right symmetrical fixed boxes are fixed on the rear end surface of the rear clamping plate, a rotating rod is rotatably connected in the fixed box, a torsion spring is connected between the rotating rod and the fixed box, a guide slide groove is opened on the outer periphery of the rotating rod, and a support ring is slidably connected in the guide slide groove, and a push spring is connected between the support ring and the side wall of the guide slide groove, and two left-right symmetrical sliding cavities are opened on the front clamping plate, the rear end surface of the support ring abuts against the front end surface of the front clamping plate, and the support ring and the sliding cavity are both arranged in a circular ring, and a protruding end or a protruding opening is provided at one end.

[0007] The beneficial effects of the utility model are:

[0008] During installation, the rotating rod is rotated to make the supporting ring on the rotating rod fit with the front clamping plate, and abut against the end face of the front clamping plate under the spring thrust of the push spring. The front clamping plate is close to the rear clamping plate under the spring thrust of the push spring, so that the rear clamping plate and the front clamping plate are clamped on the outer periphery of the filter cartridge, which is convenient and quick.

[0009] During disassembly, by rotating the rotating rod, the rotating rod assists in rotation under the action of the torsion spring force of the torsion spring, and the support ring moves backward under the spring thrust of the push spring and abuts against the rear side wall of the guide groove. After the front clamping plate loses the support of the support ring, the thrust spring pushes the front clamping plate forward, so that the rear clamping plate is separated from the front clamping plate, thereby realizing quick disassembly.

[0010] The installation and disassembly are convenient and fast, saving time and effort. Through the balance of two forces between the thrust spring and the push spring, it can adapt to the installation between the installation port and the filter cartridge of different sizes, thereby improving the use effect.

A thrust spring 16 is connected between the fixed frame 14 and the guide slide frame 15. Two left-right symmetrical fixed boxes 18 are fixed on the rear end surface of the rear clamping plate 12. A rotating rod 17 is rotatably connected in the fixed box 18. A torsion spring 20 is connected between the rotating rod 17 and the fixed box 18. A guide slide groove 25 is provided on the outer periphery of the rotating rod 17. The guide slide groove 25 is slidably connected to a support ring 19. A thrust spring 21 is connected between the support ring 19 and the side wall of the guide slide groove 25. Two left-right symmetrical sliding cavities 22 are provided on the front clamping plate 13. The rear end surface of the support ring 19 abuts against the front end surface of the front clamping plate 13. The support ring 19 and the sliding cavity 22 are both arranged in a circular ring, and one end is provided with a protruding end or a protruding opening.

[0023] The filter cartridge 11 is inserted between the two installation openings 10. A rear clamping plate 12 and a front clamping plate 13 are provided at the periphery of the filter cartridge 11. After the filter cartridge 11 is installed on the installation opening 10, the rotating rod 17 is in a stationary state under the connection at the torsion spring 20. Under the spring thrust of the thrust spring 16, the rear clamping plate 12 is fixed in a prohibited state, and the guide slide 15 fixedly connected to the rear clamping plate 12 is prohibited. The thrust spring 16 applies a forward spring thrust to the rear end portion of the fixing frame 14, and the front clamping plate 13 is in a prohibited state. The front clamping plate 13 is moved toward the end away from the rear clamping plate 12 by the spring thrust at the fixedly connected fixing frame 14, and the support ring 19 is abutted against the front end surface of the front clamping plate 13 by the thrust of the push spring 21 on the support ring 19, and the backward thrust of the front clamping plate 13 supported by the support ring 19 offsets the forward thrust of the rear clamping plate 12, and pushes the front clamping plate 13 to move toward the end of the rear clamping plate 12, so that the elastic pads 24 on the inner end surfaces of the rear clamping plate 12 and the front clamping plate 13 fit the outer peripheral surface of the filter cartridge 11;

[0024] During disassembly, the user rotates the rotating rod 17 so that the support ring 19 is longitudinally arranged as shown in FIG. Figure 2 , 5 6 (the protruding block at the support ring 19 is set upward) is converted to a horizontal setting, the support ring 19 corresponds to the slide cavity 22 front and back, and the support ring 19 passes through the slide cavity 22 under the spring thrust of the push spring 21, so that the front clamping plate 13 loses the support with the support ring 19, and the front clamping plate 13 moves forward under the spring thrust of the thrust spring 16, thereby causing the filter cartridge 11 to lose the clamping of the front clamping plate 13;

[0025] like Figure 5 As shown, the support ring 19 is in a longitudinal setting, and the torsion spring 20 is in a curled setting. The support ring 19 is subjected to a spring thrust from the push spring 21, and is subjected to a torsion spring force applied to the rotating rod 17 by the torsion spring 20. The support ring 19 is kept in a stationary state by the friction force between the support ring 19 and the front clamping plate 13. The user applies a rotational thrust to the rotating rod 17 to destroy the balance, so that the support ring 19 rotates and resets, and the support ring 19 corresponds to the sliding cavity 22 front and back.
