Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial and mining equipment technology, and in particular to a device for uniformly spreading crystalline titanium liquid slurry. Background Technology
[0002] Vacuum belt filters are a new type of highly automated filtration equipment. Using filter cloth or mesh as the filter medium, the slurry is horizontally arranged on the filter medium, fully utilizing the gravity of the slurry and vacuum suction to achieve solid-liquid separation. Vacuum belt filters are suitable for materials under various concentration conditions and have high filtration efficiency, thus being preferred by many industries.
[0003] The vacuum belt filter press features continuous automation in feeding, filtration, washing, slag removal, and filter cloth cleaning, improving production efficiency, reducing operating costs, significantly reducing labor intensity, and improving the working environment. Material passes through the sedimentation zone, with large particles at the bottom and small particles at the top, resulting in a rational filter cake structure and low resistance to filtrate permeation, enabling rapid thin-layer filtration.
[0004] Chinese utility model patent (authorization announcement number: CN210674436U) Name: A feeding device for a belt vacuum filter. The device includes a motor, main conveyor roller, auxiliary conveyor roller, negative pressure chamber, baffle, annular belt, and annular filter cloth. The feeding device includes a feeding pipe, a lifting and leveling mechanism, and a lifting and leveling mechanism. After the slurry enters the annular belt, the moisture in the slurry is absorbed by the negative pressure chamber through the annular filter cloth, achieving a filtration effect. The lifting and leveling mechanism allows the slurry entering the annular belt to be evenly spread, ensuring a consistent thickness on the belt. Both mechanisms have lifting functions to adjust the slurry thickness on the belt. Different negative pressure intensities and filtration times correspond to different slurry thicknesses. During filtration in the negative pressure chamber, moisture in different parts of the slurry can be effectively filtered out. This feeding device improves the filtration effect of the belt vacuum filter and ensures product quality. However, the threaded connection of the leveling plate results in poor stability, making it prone to rotation during use and affecting the uniform spreading of the slurry. Utility Model Content

[0028] like Figure 1 , 2As shown in Figure 5, a device for uniformly spreading crystalline titanium liquid slurry includes a belt conveyor body 1 and a filter cloth 2 with closed ends. The filter cloth 2 is sleeved on the belt of the belt conveyor body 1 and is attached to the upper layer of the belt. A negative pressure box 3 is fixed inside the frame of the belt conveyor body 1. An air inlet groove 4 is opened on the top of the negative pressure box 3. An exhaust pipe 5 penetrating the frame is installed on the side wall of the negative pressure box 3. An air hole 6 is opened on the belt above the air inlet groove 4. An installation beam 16 is fixed at the discharge end of the belt conveyor body 1 and spans the belt. The bottom of the mounting beam 16 is provided with a mounting groove, which extends along the mounting beam 16. The top of the mounting beam 16 is provided with a countersunk hole 17 that passes through the mounting groove. A bolt 18 is installed in the countersunk hole 17, and a clamping block 19 that matches the mounting groove is screwed onto the bolt 18. The clamping block 19 is used to clamp the upper part of the scraper 20 in the mounting groove. The scraper 20 is fixed to the bottom of the mounting beam 16 by the clamping block 19. The connection method is more stable, the scraper 20 is not easy to loosen or fall off, the frequency of later maintenance and adjustment is reduced, and the uniform spreading of slurry is ensured.
[0029] In this embodiment, as Figure 1 , 2 As shown in Figure 5, the upper half of the clamping block 19 has an isosceles trapezoidal cross-section. The bolt 18 is screwed onto the top surface of the clamping block 19. The countersunk hole 17 is an oblong hole, with its length parallel to the conveying direction of the belt. During installation, after the waist of the trapezoid contacts the groove of the mounting slot, the clamping block 19 gradually guides itself until it is fully inserted into the mounting slot to clamp the scraper 20. There is no need for manual insertion of the clamping block 19 into the mounting slot and then tightening of the bolt 18. The structure is simple and easy to install, reducing the labor intensity of workers.
[0030] In this embodiment, as Figure 1 , 2 As shown in Figure 4, a skirt 7 is provided along the edge of the belt. A V-shaped groove 8 is provided on the outer wall of the skirt 7. There are several V-shaped grooves 8, which are evenly distributed along the edge of the skirt 7. The filter cloth 2 covers the inner wall of the skirt 7. The V-shaped groove 8 on the outer wall of the skirt 7 reduces the stress during deformation, ensures that the skirt 7 can pass smoothly through the drive shaft, avoids cracking, and also avoids gaps between the inner wall and the filter cloth 2 that could lead to air leakage, thus improving the filtration effect.
[0031] In this embodiment, as Figure 1-4 As shown, a secondary shaft 9 is rotatably mounted on the frame at the discharge end of the belt conveyor body 1. The secondary shaft 9 is located below the belt and is used to separate the belt from the filter cloth 2 at the discharge end. A scraper is also installed on the frame below the secondary shaft 9. The scraper is used to scrape off the material on the filter cloth 2. The filter cloth 2 is peeled off by the secondary shaft 9, which facilitates the removal of the dewatered material. With the use of the scraper, the removal of the material can be more thorough.
[0032] In this embodiment, as Figure 1-4 As shown, a row of support columns 10 is fixed inside the frame. The row of support columns 10 is evenly distributed along the belt conveying direction of the belt conveyor body 1. The negative pressure box 3 is fixed inside the frame through the support columns 10, and the top of the support columns 10 is flush with the top of the negative pressure box 3. The support columns 10 are in line contact with the belt, which can ensure the support of the belt and reduce the wear of the belt.
[0033] In this embodiment, as Figure 1-4 As shown, the belt has several evenly distributed air grooves 11. The air grooves 11 extend along the conveying direction perpendicular to the belt. Each air groove 11 has an air hole 6 at its bottom, which increases the water absorption area of the filter cloth 2 in the cross section (the surface perpendicular to the conveying direction of the belt) of the negative pressure box 3, and improves the dewatering speed of the material.
[0034] In this embodiment, as Figure 1-4 As shown, the scraping component includes a crossbeam 12 and a mounting frame 13. The crossbeam 12 is mounted on the frame at the discharge end and is located below the filter cloth 2. One end of the mounting frame 13 is connected to the crossbeam 12, and the other end is equipped with a scraper 14. The scraper 14 is in contact with the filter cloth 2. The scraper 14 removes the clumps on the filter cloth 2, keeps the surface of the filter cloth 2 clean, and ensures the filtration effect of the filter cloth 2.
[0035] In this embodiment, as Figure 1-4 As shown, the mounting frame 13 is hinged to the crossbeam 12. A spring 15 is connected to the side wall of the mounting frame 13 near the scraper 14. The other end of the spring 15 is connected to the frame. The mounting frame 13 is made movable so that the scraper 14 can always be in close contact with the surface of the filter cloth 2.
[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
