Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid separation equipment, in particular to a belt-type concentrated filter press equipment. Background Art

[0002] As a highly efficient solid-liquid separation equipment, belt-type concentration filter press equipment plays an important role in many fields such as sewage treatment, mining, chemical industry and other industries.

[0003] In the existing technology, belt-type concentrating filter press equipment is usually composed of a frame, a drive device, a filter belt, a concentrating section, a discharge device and a control system. The material enters the concentrating section, and under the action of gravity and the tension of the filter belt, the liquid part seeps out through the pores of the filter belt. After entering the filter press section, the material is squeezed by the pressing roller to further remove moisture and become a mud cake. The filter belt is then driven by the drive device to continue to operate and the treated mud cake is transported to the discharge guide plate.

[0004] However, when the filter belt transports the mud cake to the discharge guide plate, gravity alone cannot make the material fall completely, causing part of the mud cake to stick to the surface of the filter belt, resulting in incomplete unloading and affecting production efficiency. The residual mud cake will be mixed with new materials in the next round of operation, affecting the stability of product quality. Utility Model Content

The surface of the fixed plate 4 overlaps the support plate 8, and the surface of the support plate 8 is slidingly connected to the extension plate 5 and the scraper 6. The spring 17 between the extension plate 5 and the support plate 8 ensures that the scraper 6 is always tightly fitted to the surface of the two filter belts 2, and the material after filtration is scraped off from the filter belt 2, which speeds up the unloading process, improves the overall processing efficiency of the equipment, and ensures the continuity and stability of production. A retractable stopper 13 is set on the surface of the support plate 8 to press against the surface of the fixed plate 4, and a rotatable and screwable rotating rod 16 is set between the scraper 6 and the extension plate 5 to realize the separate disassembly and installation of the support plate 8 and the scraper 6, saving replacement costs and improving the maintenance efficiency of the scraper 6 mechanism. Example 2

[0024] See also Figure 3On the basis of Example 1, in order to realize the disassembly and installation of the support plate 8, the support plate 8 has a square plate structure, and plugging plates 10 are fixedly connected on both sides of the bottom surface of the support plate 8. The plugging plates 10 have a square plate structure, and a stop groove 11 is opened on the surface of the plugging plate 10. A rubber block 12 is fixedly connected to the center position of the stop groove 11, and blocks 13 are fixedly connected to the two side surfaces of the rubber block 12. The block 13 has a square block structure, and the ends of the two blocks 13 away from each other are provided with an inclined surface. Each group of fixed plates 4 is provided with two, and the fixed plate 4 has a "U"-shaped plate structure. A through hole 9 is opened on the bottom surface of the fixed plate 4. The through hole 9 is a square hole. The plugging plate 10 passes through the surface of the through hole 9, pressing the block 13 against the surface of the fixed plate 4.

[0025] An inclined surface is provided on the surface of the two blocks 13. When the support plate 8 is overlapped on the surface of the fixed plate 4, one end of the inclined surface of the block 13 is squeezed by the through hole 9, and the block 13 is squeezed into the blocking groove 11. At this time, the rubber block 12 changes from its original state to a compressed state. When the block 13 passes through the surface of the through hole 9, the block 13 loses the pressure, and the rubber block 12 returns to its original state from the compressed state, driving the block 13 to pop out of the blocking groove 11 and press against the surface of the fixed plate 4, thereby realizing rapid fixation and disassembly of the support plate 8. Example 3

[0026] See also Figures 4 and 5 On the basis of the second embodiment, in order to ensure that the scraper 6 is always in contact with the surface of the filter belt 2 and to replace the scraper 6, an extension hole 14 is provided on the surface of the support plate 8. The extension hole 14 is a square hole. The extension plate 5 is slidably connected to the surface of the extension hole 14. The extension plate 5 is a "T"-shaped plate structure. A limiting hole 18 is provided on both sides of the surface of one end of the extension plate 5. The limiting hole 18 is a circular hole. The surface of the limiting hole 18 passes through the limiting column 7. The surface of the extension plate 5 away from the limiting hole 18 is provided with screws on both sides. Groove 15, the limiting column 7 is a circular plate structure with a "T"-shaped cross section, one end of the limiting column 7 is fixedly connected to the surface of the support plate 8, the spring 17 is sleeved on the surface of the limiting column 7, one end of the spring 17 is fixedly connected to the surface of the support plate 8, and the spring 17 is in a stretched state, the rotating rod 16 is a circular plate structure with a "T"-shaped cross section, one end of the rotating rod 16 is rotatably connected to the surface of the scraper 6, and a threaded portion 19 is provided on the surface of the end of the rotating rod 16 away from the scraper 6, and the threaded portion 19 is matched with the threaded groove 15 and connected to each other.

[0027] A spring 17 is provided, and the spring 17 is in a stretched state, driving the extension plate 5 to have a tendency to move toward one end of the filter belt 2. The extension plate 5 drives the scraper 6 to always be closely attached to the surface of the filter belt 2. The limiting column 7 is provided to guide and limit the extension plate 5, and the spring 17 is sleeved on the surface of the limiting column 7 to support the spring 17, thereby avoiding fatigue deformation of the spring 17 after long-term use and improving the service life of the spring 17. One end of the rotating rod 16 is provided to be rotatably connected to the surface of the scraper 6, which can not affect the connection between the threaded portion 19 at one end of the rotating rod 16 and the threaded groove 15, thereby realizing the separate removal and installation of the scraper 6 and there is a gap between the two rotating rods 16, so that the mud cake scraped by the scraper 6 can be discharged.

[0028] In actual use, first screw the end of the rotating rod 16 with the threaded portion 19 into the threaded groove 15 on the surface of the extension plate 5, then overlap the support plate 8 on the surface of the fixed plate 4 and press downward, and the stopper 13 is squeezed into the stopper groove 11. When the stopper 13 passes through the surface of the through hole 9, the stopper 13 loses its pressure, and the rubber block 12 returns to its original state from the compressed state, driving the stopper 13 to pop out of the stopper groove 11 and press against the surface of the fixed plate 4. At this time, the spring 17 is in a stretched state and has a tendency to rebound to its original state, so that the scraper 6 is always closely attached to the surface of the filter belt 2, and the scraped mud cake reaches the discharge plate from the gap between the two rotating rods 16, ensuring that the mud cake on the surface of the filter belt 2 can be completely scraped off.
