Description

Technical Field

[0001] The utility model relates to the technical field of industrial hose pumps, in particular to a disassembly-free stepless adjustment industrial hose pump. Background Art

[0002] Industrial hose pump, also known as peristaltic pump, is a positive displacement pump widely used in chemical, food processing, pharmaceutical, mining and other industrial fields; the core working principle of the pump is to periodically squeeze the rubber hose in the pump cavity through the roller or sliding shoe on the rotor to form a sealed cavity to achieve the suction and extrusion of the fluid.

[0003] The existing problems with industrial hose pumps are: the working efficiency of the hose inside the pump decreases due to wear; specifically, as a vulnerable rubber part, the hose is continuously squeezed and rubbed by the pressure roller and the shell during operation, causing it to wear, become thinner, and age and soften, resulting in a continuous decrease in the vacuum degree of the sealing cavity inside the hose. After about 500 hours of use, the hose pump will begin to show a significant decrease in flow and lift.

[0004] The patent with application number 202211192466.7 discloses a peristaltic pump with adjustable pressure tube gap, including a pump body, a drive motor, and a pressure wheel. An arc-shaped pipe groove is opened inside the pump body, the drive motor is fixed on the outer wall of the pump body, and the output shaft of the drive motor extends into the pump body. A mounting block is arranged inside the pump body, and the mounting block is fixedly connected with the output shaft of the drive motor through it. Two mounting plates are symmetrically fixedly connected on both sides of the mounting block, and two bracket plates are symmetrically fixedly connected on the side walls of each mounting plate. There are two pressure wheels, and the top and bottom of the pressure wheel are rotatably connected with threaded sleeves. The bracket plate is provided with a long waist-shaped mounting hole for the threaded sleeve to pass through. The mounting block is also symmetrically fixedly connected with an arc-shaped back plate, and the outer periphery of the back plate has an arc-shaped groove. In this patent, the gap between the pressure wheel and the hose can be adjusted by moving the threaded sleeve along the mounting hole and fixing it with screws after moving.

[0005] The disadvantages of the patent with application number 202211192466.7 are: 1. The pressure wheel is only fixed to the bracket plate by screws and threaded sleeves, which is not stable enough and is easy to slide toward the output shaft; 2. The adjustment distance of the pressure wheel is not easy to control; 3. The outer shell needs to be disassembled when adjusting the pressure wheel, which is inconvenient. Utility Model Content

[0007] In order to achieve the above-mentioned purpose, the utility model provides a disassembly-free stepless adjustment industrial hose pump, including a shell, a rotor driven by a main shaft is arranged in the shell, the rotor is connected to a pressure roller shaft, the pressure roller shaft is connected to a pressure roller wheel and a fastening bolt for fixing the pressure roller shaft and the rotor; U-shaped grooves are arranged on the left and right ends of the rotor, the pressure roller shaft is movably connected in the U-shaped groove, the pressure roller shaft is fixedly connected to a thimble, the thimble is connected to a rotary adjustment bolt, one end of the rotary adjustment bolt is provided with a socket movably connected to the thimble, and the other end is threadedly connected to the rotor, and the position of the pressure roller wheel can be adjusted by rotating the rotary adjustment bolt.

[0008] Furthermore, an operating hole for adjusting the screw bolt is provided on the rotor.

[0009] Furthermore, a detachable transparent cover is provided on the shell at a position opposite to the operation hole.

[0010] Furthermore, an anti-slip hook is connected to the fastening bolt, and a bent hook portion is provided on the anti-slip hook. The bent hook portion is located in the operating hole, and the bent hook portion is used to hook the operating hole to prevent the pressure roller shaft from slipping when the pressure roller shaft slips outward.

[0011] Furthermore, the anti-drop hook is provided with a connection hole for connecting with a fastening bolt.

[0012] Furthermore, the anti-drop hook is provided with a through slot for the ejector to pass through.
