Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, in particular to a lifting device for an internal reflux pump. Background Art

[0002] The internal return pump is a commonly used device in the sewage treatment process, especially in the aeration tank. Its function is to maintain the sewage slurry in the sludge tank in the state of activated sludge, thereby maintaining a stable suspended solids concentration in the aeration tank. This ensures a uniform sludge concentration in the aeration tank, which is crucial for sewage treatment. Due to the poor working environment of the internal return pump, the internal return pump needs to be removed and repaired regularly, which requires the use of a lifting device. However, most internal return pump lifting devices, when mounting the internal return pump, continuously adjust the position of the hook to hang the rope reserved for the internal return pump for lifting. The success rate of this method of mounting is not high, and it often takes multiple attempts to hang the hook, resulting in a waste of operating time. In addition, the internal return pump is sometimes installed between two sewage tanks, leaving the operating area for the lifting device with only the width of a wall. Most lifting devices are difficult to arrange in such an environment. Utility Model Content

[0013] Beneficial effects of the utility model:

[0014] 1. Compared with the traditional internal return pump lifting device, when mounting the internal return pump, the position of the hook is constantly adjusted to hang the rope reserved for the internal return pump for lifting. The success rate of this method of mounting is not high, and it often takes multiple attempts to hang the hook, resulting in a waste of operation time. In addition, the internal return pump is sometimes installed between two sewage pools, leaving the operating area of the lifting device with only the width of a wall. Most lifting devices are difficult to arrange in such an environment. This device facilitates the mounting of the internal return pump by using magnetic attraction and adding a layout structure that adapts to narrow walls, and can be arranged along the edge of a narrow wall.

[0015] 2. During lifting, the grab seat is fixed to the perforated seat originally used for threading the rope of the internal return pump through a threaded connector, thereby connecting to the internal return pump. The grab seat usually stays in the sewage together with the internal return pump. During maintenance and lifting, the motor drives the winding roller and the lifting seat to rotate. With the extension of the extension arm and the guide roller, the traction rope is released away from the device, causing the magnetic block under the mounting seat to descend. As the magnet block slowly descends, the magnet block guides the mounting seat to align with the grab seat and fit it together through magnetic force. Then the motor drives the winding roller to rotate in the opposite direction, rewinds the traction rope, and drives the fixed block upward through the hook, and the internal return pump is lifted. Under the gravity of the pump and the magnetic force of the magnet block, the sliding rod slides in the guide seat. Since the fixed block limits the distance between the two sets of sliding rods, the guide seats are relatively separated. Through the meshing rotation of the two sets of gears, the grab hooks are brought close to each other to grab and fix the grab seat, so that the internal return pump can be lifted as the traction rope is reeled in. In this process, the spring is in a compressed state during the descent of the guide seat, keeping the two sets of guide seats closed and the two sets of grab hooks open. The limit block prevents the sliding rod from sliding out of the guide seat, so as to solve the problem that most internal return pump lifting devices are not convenient to mount and are not suitable for some environments.

[0016] 3. When it is necessary to lift the partition wall between two groups of sewage pools, slide the sliding seat to the base through the sliding groove. After sliding the sliding seat to the appropriate position, tighten the bolts and move it downward to press against the base. The sliding seat is fixed by friction to complete the installation. The clamping seat is installed with a clamping roller that rolls on the wall, and the support seat is installed with a supporting roller that rolls along the wall. The clamping roller and the supporting roller make it easy to move the device to the appropriate position for lifting. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] When it is necessary to lift the partition wall between two groups of sewage pools, the sliding seat 302 is slidably connected to the base 1 through the sliding groove 301.
