[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 - 7 , the present utility model provides a technical solution:

[0026] A new type of washing liquid distributor for a titanium dioxide filter includes a feed inlet 9, a water outlet, a cloth cylinder 7, and a rigid framework. The feed inlet 9 conveys the washing liquid to both ends of the washing liquid distributor through a support plate at the bottom of the washing liquid distributor. The water outlet is arranged at the bottom of the cloth cylinder 7. Some holes are opened at the bottom of the support plate according to actual operation, which can make the water distribution more uniform. The rigid framework is composed of an outer support 1, an inner support 15, and a cylindrical steel frame 4. The cloth cylinder 7 is positioned and locked with the outer support 1 and the inner support 15 respectively through fastening bolts 3; the cloth cylinder 7 is connected to the rigid framework as a whole through fastening standard parts. The two ends of the cloth cylinder 7 and the sealing plate 14 are formed into a sealed distributor main body through hot air plastic welding. The new type of washing liquid distributor device has a simple structure, is convenient to clean, has a low cost, and stable performance. Through the characteristics of liquid overflow and fluidity, etc., the water distribution is uniform and reliable, and the fluctuation is small.

[0027] Furthermore, the washing liquid distributor further includes a handwheel 10, a fixing block 11, and an adjusting screw 12. These components are connected to the cloth cylinder 7 through a self-made bolt 13. By rotating the handwheel 10, the sluice gate 8 moves up and down, thereby adjusting the flow rate of the water outlet of the distributor, and further making the water distribution uniform.

[0028] Furthermore, the washing liquid distributor further includes a strip-shaped ear plate 17, a reinforcing rib 16, a cylinder steel frame, a water distribution rubber plate 18, and a pressing strip 19. The strip-shaped ear plate 17 is welded to the cloth cylinder 7 by hot air plastic welding; one end of the reinforcing rib 16 is connected to the cylinder steel frame through a fastening standard part, and the other end is connected to the strip-shaped ear plate 17 through a fastening standard part, that is, connected to the cloth cylinder 7 as a whole; the water distribution rubber plate 18 and the pressing strip 19 are also connected to the distributor as a whole through fastening standard parts. The water outlet of the distributor is diffused through the plane of the water distribution rubber plate 18. The water outlet of the distributor is further diffused through the plane of the water distribution rubber plate 18, making the water distribution more uniform.

[0029] Furthermore, there are two process holes provided above the cloth cylinder 7. Purpose 1: Used as a cleaning hole and an observation port. Purpose 2: Used as a hand hole for installing the connecting standard parts of the adjusting screw 12 and the sluice gate 8. The adjusting screw 12 and the sluice gate 8 are connected through standard parts.

[0030] Furthermore, rectangular holes are opened at both ends of the sealing plate 14. Purpose 1: Facilitate the installation of the sluice gate 8. Purpose 2: Facilitate the internal cleaning during shutdown maintenance. The rectangular holes are sealed by using the cleaning cover plate 5, the PTFE gasket 6, and the fastening standard parts.

[0031] Furthermore, there is a row of rectangular holes with unequal intervals and the same size at the bottom of the cloth cylinder 7, so that at a certain rotational speed, the washing water amount in the same area is the same. This rectangular hole is the water outlet. The intervals of the rectangular holes are separated by dividing the circular disk surface of the filter into multiple concentric rings with equal widths according to the area ratio of each concentric ring.

[0032] Furthermore, the cloth cylinder 7 is a key component of the washing liquid distributor. By calculating the production capacity, flow rate, etc. of the filter and referring to the conventional PP pipe diameters on the market, the final pipe diameter is determined to save costs. The height adjustment of the cloth cylinder 7 from the disk surface is adjusted by the suspension screw 2. After adjusting to the appropriate height, it is positioned and locked with the outer support 1 and the inner support 15 respectively through the fastening bolts 3.

[0033] Furthermore, the material of the washing liquid distributor is PP. The material of traditional washing liquid distributors is usually stainless steel. Its internal structure is relatively complex and the manufacturing cost is high. Due to the corrosive characteristics of the washing liquid, the stainless steel material is easily corroded and perforated, resulting in a short service life. Using PP material can effectively resist the corrosion of acid, alkali, salt solutions and various organic solvents. At the same time, the cloth cylinder also uses PP pipes with common pipe diameters in the market, and the processing and manufacturing cost is much lower than that of stainless steel, reducing the cost while increasing the service life.
