[0023] In the embodiment, the screen frame 4 is provided with a sealing cover plate 5, and the inner side of the sealing cover plate 5 corresponding to the screen frame 4 is provided with a thorn screen cleaning mechanism. The thorn screen cleaning mechanism comprises a bottom plate 6 and a telescopic rod 7. The bottom plate 6 is distributed with thorns 601 corresponding to the screen holes of the screen frame 4. The telescopic rod 7 is connected to the bottom plate 6 and is installed on the inner side of the sealing cover plate 5. The bottom plate 6 is pressed on the screen frame 4, so that the thorns 601 clean the screen holes of the screen frame 4. The sealing cover plate 5 is provided with a flushing assembly, and a plurality of flushing nozzles 602 are arranged on the bottom plate 6. The flushing assembly is connected to the flushing nozzles 602. When it is necessary to process the sundry blockage on the screen, the telescopic rod 7 is first controlled to press the bottom plate 6 on the screen frame 4, so that the thorns 601 clean the screen holes of the screen frame 4 and push out the blockage. At the same time, the flushing nozzles 602 flush the screen holes of the screen, so as to ensure that the screen holes are not blocked.
[0024] In the embodiment, the hydraulic telescopic mechanism comprises a hydraulic telescopic rod 11, an inclination sensor 21 and an inclination adjustment button 17. One end of the hydraulic telescopic rod 11 is fixed on the support frame 1, and the other end is movably connected to the screen frame 4. The inclination of the screen frame 4 is adjusted in the process of telescoping. The inclination sensor 21 is arranged on the screen frame 4 and is used for detecting and uploading the inclination data. In the process of use, the inclination adjustment button 17 is pressed, the hydraulic telescopic rod 11 is controlled to move through circuit signal transmission, the upper end of the screen frame 4 is rotated on the support frame 1 through the rotating shaft 10, the inclination of the screen frame 4 is adjusted, and the inclination data of the screen frame 4 is detected and uploaded by the inclination sensor 21. In the embodiment, the inclination angles of 45° and 30° are listed. Generally, for the material with good fluidity, the inclination angle can be appropriately increased to improve the production capacity, for example, the inclination angle of 45°. For the material prone to blockage or adhesion, the inclination angle should be appropriately reduced to ensure the continuity and stability of the screening, for example, the inclination angle of 30°.
[0025] I. Definition of the inclination angle of the screen surface;
[0026] The inclination angle of the screen frame 4 refers to the angle between the screen surface and the horizontal plane. The size of the angle has a significant influence on the movement trajectory of the material on the screen surface and the screening effect.
[0027] II. Influence of the inclination angle of the screen surface on the screening effect;
[0028] Movement trajectory of the material: When the screen surface has a certain inclination angle, the movement speed of the material on the screen surface will be affected by the acceleration of gravity, so that the material is more likely to flow downward on the screen surface. This flow mode is beneficial to the dispersion and uniform distribution of the material, thereby improving the screening efficiency and the utilization rate of the screen.
[0029] Separation efficiency: Proper inclination angle can improve the separation efficiency of the material. Due to the existence of the inclination angle, the material flows more easily on the screen surface, making the fine particles pass through the screen more quickly, thus improving the classification effect of the material. At the same time, the inclination angle also helps to prevent the material from blocking the screen, further improving the continuity and stability of the screening.
[0030] Production capacity: Within a certain range, increasing the inclination angle of the screen surface can improve the production capacity of the equipment. This is because the increase of the inclination angle makes the material move faster on the screen surface, shortens the residence time of the material on the screen surface, and thus improves the processing capacity of the equipment. However, it should be noted that too large inclination angle may affect the distribution and flow of the material, which may reduce the screening efficiency.
[0031] Maintenance: In the long-term use process, the wear of the screen is a problem that cannot be ignored. Proper inclination angle can reduce the impact and friction of the material on the screen, thus prolonging the service life of the screen. In addition, the setting of the inclination angle also helps to facilitate the cleaning and maintenance of the equipment, reducing unnecessary downtime and production cost.
[0032] Three, choose the appropriate inclination angle;
[0033] In practical application, the appropriate inclination angle should be selected according to the specific material characteristics and production requirements. Generally speaking, for the material with good flowability, the inclination angle can be appropriately increased to improve the production capacity; while for the material that is easy to block or adhere, the inclination angle should be appropriately reduced to ensure the continuity and stability of the screening. In addition, according to the actual production needs and equipment specifications, professional technical personnel or reference to the suggestions of equipment manufacturers can be consulted to determine the best inclination angle range, which is not limited here.
[0034] In summary, the inclination angle of the screen surface is one of the important parameters affecting the screening effect. By reasonably setting the inclination angle, the motion trajectory and distribution of the material can be optimized, and the separation efficiency, production capacity and maintenance level of the equipment can be improved. Therefore, the operator should pay attention to observe and adjust the inclination angle when operating the screening equipment to obtain the best screening effect.
[0035] In this embodiment, the diameter of the sharp 601 is smaller than the screen hole diameter of the screen frame 4; the sharp 601 is inserted into the screen hole to push out the blocked sundries.
[0036] In the embodiment, the flushing assembly comprises a high-pressure water inlet pipe 8 and a water inlet electromagnetic valve 9. The high-pressure water inlet pipe 8 penetrates the sealing cover plate 5 and the bottom plate 6, and is connected with the flushing nozzle 602 and an external water source. The water inlet electromagnetic valve 9 is arranged on the high-pressure water inlet pipe 8 and is used for flushing the screen. When the spikes 601 are inserted into the screen holes, the clogged sundries are pushed out, and the flushing nozzle 602 flushes the screen holes of the screen, so that the screen holes are not clogged. Of course, the spike screen cleaning mechanism and the flushing assembly can be used separately to realize the functions of pushing out the clogged sundries and flushing, respectively.
[0037] In the embodiment, the water power screen body is provided with a liquid discharge port 14. The liquid discharge port 14 is connected with a catalyst recovery tank 12 through a liquid discharge valve 15 and an inclined pipe. The catalyst recovery tank 12 is provided with a filter screen 13 at the top and is used for recovering the catalyst. After the sewage is treated by the screen, the sewage vertically falls into the catalyst recovery tank 12 through the liquid discharge port 14. When the catalyst is used in the sewage, the filter screen 13 can intercept and recover the catalyst.
[0038] In the embodiment, the sealing cover plate 5 is made of transparent material and covers the screen frame 4, so that the sealing property of the water flow during the cleaning process is ensured.

The inclination sensor 21 can be wirelessly connected with the display panel 16 and is used for receiving the inclination angle data of the screen frame 4. During use, the inclination adjusting button 17 is pressed to generate a control signal which is transmitted to the microcontroller 20. The microcontroller 20 converts the signal and controls the hydraulic telescopic rod 11 to move, so as to adjust the inclination angle of the screen frame 4. The inclination angle data of the screen frame 4 is detected by the inclination sensor 21 and is uploaded to the display panel 16 for data display. The operator should pay attention to the observation and adjustment of the inclination angle when operating the screening equipment, so as to obtain the best screening effect. The pressing button 18 is pressed to transmit the circuit signal, so that the telescopic rod 7 presses the bottom plate 6 on the screen frame 4. The spikes 601 clean the screen holes of the screen frame 4 and push out the clogged sundries. At the same time, the flushing button 19 is pressed to control the flushing nozzle 602 to flush the screen holes of the screen, so that the screen holes are not clogged.
