Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a grab bucket mechanism of a grab bucket type sewage remover. Background Art

[0002] Grab-type screen cleaners are commonly used in municipal sewage treatment, rivers, pumping stations, etc. Their main function is to clean large floating objects and solid particles at the bottom of the pool that are intercepted by the screens. However, many pumping stations and sewage treatment plant pretreatment sections currently have an increasing demand for sand removal. Moreover, these pretreatment sections are usually designed with deep channels, which is difficult to meet with other types of screen systems.

[0003] Therefore, this solution improves and derives a special sand dredging device based on the conventional grab-type screen decontamination machine to meet the special requirements of the sand removal project. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model fully covers the gaps inside and on both sides of the grab-type grille dirt remover claw with a stainless steel filter, thereby enabling the claw to effectively remove fine sand particles.

[0005] A grab mechanism of a grab-type sewage remover includes: a vertical part of a grab and a curved part of the grab. The curved part of the grab is rotatably mounted on the vertical part of the grab. A sliding track is designed at the rear of the grab mechanism for the grab to slide down to the bottom of the channel to clean sand. A roller is installed on the rear end face of the vertical part of the grab. During the movement of the grab in the channel, the roller can run stably in the sliding track. The inner side of the curved part of the grab, the inner side of the vertical part of the grab and the leaky parts on both sides are all covered with filter screens to form a curved and closed grab.

[0006] As a preferred solution of the present invention, a collision block is installed at the closed part of the curved part of the gripper to prevent sand leakage and to cushion vibration.

[0007] As a preferred solution of the present invention, the collision block is made of nylon material.

[0008] As a preferred solution of the present invention, the filter screen is made of stainless steel.

[0009] As a preferred solution of the present invention, the filter screen is installed by welding.

[0010] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0011] This new grab-type screen desludging machine effectively removes fine sand particles by fully covering the inner and outer gaps of the claws with stainless steel filters, meeting the needs of deep channel desludging projects. The nylon impact block design not only prevents sand leakage but also acts as a shock absorber, extending the life of the grab. This simple structure and easy operation make it suitable for a variety of deep channel desludging projects and has broad application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] Example 1

[0017] like Figure 1 、 Figure 2 As shown, a specific embodiment of the grab mechanism of a grab-type garbage remover described in the present invention includes: a vertical portion 3 of the grab and a curved portion 4 of the grab. The curved portion 4 of the grab is rotatably mounted on the vertical portion 3 of the grab. A sliding track is designed at the rear of the grab mechanism for the grab to slide down to the bottom of the channel to clean sand. A roller 2 is installed on the rear end surface of the vertical portion 3 of the grab. During the movement of the grab in the channel, the roller 2 can run stably in the sliding track. The inner side of the curved portion 4 of the grab, the inner side of the vertical portion 3 of the grab and the empty parts on both sides are all covered with a filter screen 1 to form a curved and closed grab. The filter screen 1 is made of stainless steel and is fixed by welding. The aperture of the filter screen can be designed and determined according to the particle diameter of the intercepting medium. The empty parts on both sides of the grab are welded and fixed to the vertical portion 3 of the grab. When the curved portion 4 of the grab is closed, the size of the filter screens on both sides is just enough to completely close the two sides of the grab. The curved portion 4 of the grab is provided with sufficient curvature. When grabbing sand, the sand particles can effectively stay in the curved claw.

[0018] A collision block 5 is installed at the closed part of the curved part 4 of the gripper to prevent sand leakage and to cushion the shock. The collision block 5 is made of nylon material.

[0019] The working principle of the utility model is as follows: during operation, the grab bucket slides down to the bottom of the channel through the descending track, the vertical part 3 of the grab claw is connected to the curved part 4 of the grab claw by rotation, the curved part 4 of the grab claw is rotated to grab sand, and the filter screen 1 fully covers the inner side of the grab claw and the leaking part. When the grab bucket is closed, fine sand particles are captured by the filter screen 1, and the nylon impact block 5 prevents sand particles from leaking at the closed position and plays a shock-absorbing role. The entire mechanism has a simple structure and is easy to operate, which effectively realizes the efficient removal of sand particles in deep channels.

[0020] The components in this article are all universal standard parts or components known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods, so they will not be described in detail here.

[0021] Although the specific embodiments of the present invention are described in detail above, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by ordinary technicians in this field, various changes can be made without departing from the purpose of the present invention. Modifications or deformations that do not involve creative work are still within the scope of protection of the present invention.
