Description

Technical Field

[0001] The utility model discloses a bridge engineering mud processing device with a screen plate cleaning function, which relates to the technical field of bridge engineering. Background Art

[0002] Construction mud is primarily used in the construction of buildings and bridge pile foundations, underground tunnel shield projects, and trenchless projects. Composed of liquid and clay, supplemented with additives, it primarily protects the hole wall and carries drill cuttings out of the hole. During the drilling process, drill cuttings continuously enter the mud, causing changes in the mud's specific gravity, viscosity, and sand content. These changes no longer meet the required mud performance requirements and necessitate treatment or purification, primarily through solid-liquid separation. The drill cuttings in the mud are then separated and discharged for recycling. As we all know, the bridge engineering mud treatment device is an auxiliary device used for coarse screening of mud during bridge construction, and has been widely used in the field of bridge construction.

[0003] According to the "A Bridge Engineering Mud Treatment Device" disclosed in Chinese Patent Publication No. CN210473262U, through the fixed cylinder inside the device housing, the electric telescopic cylinder inside the fixed cylinder, and the filter screen inside the fixed ring, the electric telescopic cylinder can be used to drive the filter screen to move upward, squeeze the mud, and squeeze out the impurities in the mud, and the mud will enter the bottom of the device housing, which can effectively increase the efficiency and effect of the filtration. Through the motor and motor shaft on the electric telescopic cylinder, the filter screen can be rotated in the process of driving the filter screen upward, increasing the effect of mud filtration, which is conducive to the more practical use of a bridge engineering mud treatment device. Through the stirring rod on the fixed ring, in conjunction with the motor, the four stirring rods can be used to stir the mud during the filtration process to increase the uniformity of the mud.

[0004] However, the above device has the problem that a large amount of debris is easily retained on the filter screen, which makes it inconvenient for workers to clean the debris on the filter screen, resulting in poor filtering effect after long-term use. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a bridge engineering mud processing device with a screen plate cleaning function, which can conveniently clean the screen plate, enhance the cleaning effect, and avoid the accumulation of debris on the screen plate, which affects the filtering effect of the device.

[0006] The purpose of this utility model is achieved in this way:

[0007] A bridge engineering mud processing device with a screen plate cleaning function comprises a main structure and a stirring structure, wherein the stirring structure is fixedly connected to the bottom of the main structure;

[0008] The main structure includes a processing box body, a sieve plate is fixedly installed inside the processing box body, a driving motor is fixedly connected to the outer wall of the processing box body, a screw is fixedly connected to the output end of the driving motor, a movable seat is threadedly connected to the outer surface of the screw, the bottom of the movable seat is fixedly connected to the mounting seat, a return spring is fixedly connected to the top wall of the mounting seat, and a scraper is fixedly connected to the end of the return spring away from the mounting seat;

[0009] The stirring structure includes a stirring motor, an output end of the stirring motor is fixedly connected to a rotating shaft, and an outer surface of the rotating shaft is fixedly connected to a stirring rod.

[0010] Preferably, a feed port is provided on the top of the processing box body, and a discharge pipe is fixedly connected to the lower end of the outer wall of the processing box body.

[0011] Preferably, the outer wall of the processing box is provided with a debris discharge port, and a guide plate is provided below the debris discharge port.

[0012] Preferably, the sieve plate is arranged at an angle in the processing box, and the lower end of the sieve plate is connected to the impurity discharge port.

[0013] Preferably, one end of the scraper away from the return spring abuts against the upper surface of the screen plate.

[0014] Preferably, a guide rod is fixedly connected to the inner wall of the processing box, the guide rod passes through the movable seat and is slidably connected to the movable seat, and the guide rod is arranged parallel to the screw rod.

[0015] Preferably, one end of the screw away from the driving motor passes through the processing box and extends to the inside, and the screw is rotatably connected to the processing box via a bearing.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] First, the mud is fed into the processing box through the feed port, and the mud is filtered through the sieve plate, and the impurities in the mud are retained on the sieve plate. When too many impurities are filtered on the sieve plate, the drive motor is started to drive the screw to rotate, and the screw drives the moving seat to do reciprocating motion in the processing box, and also drives the internal scraper to clean the sieve plate, thereby driving the impurities to be discharged from the impurity discharge port. In this way, the sieve plate can be cleaned conveniently. The reset spring can make the scraper always fit on the sieve plate, thereby enhancing the cleaning effect and avoiding the accumulation of debris on the sieve plate, which affects the filtering effect of the device.

[0018] Second, by rotating the stirring rod on the shaft in conjunction with the stirring motor, the filtered mud can be stirred to increase the uniformity of the mud, which is beneficial to the subsequent use of the mud. BRIEF DESCRIPTION OF THE DRAWINGS
