Description

Technical Field

[0001] The invention relates to the technical field of screening devices, in particular to a guar gum powder fine screening device. Background Art

[0002] Guar gum, a natural high-molecular polysaccharide, is widely used in many industries such as food, petroleum, papermaking, and textiles due to its good thickening, stabilizing, and emulsifying properties. In different application scenarios, there are relatively strict requirements on the particle size of guar gum powder. For example, in the field of food additives, overly coarse powder particles may affect the taste and texture uniformity of the product; in oil extraction, guar gum powder that does not meet the particle size standards may not fully exert its performance role in fracturing fluids, etc., so the guar gum powder needs to be finely screened to ensure its quality and use effect.

[0003] However, the traditional guar gum powder screening device still has some shortcomings in use: First, guar gum powder is usually screened using simple screens or vibrating screens, which can easily lead to powder clogging the screen holes. Once the screen holes are clogged, not only will the screening accuracy be affected, resulting in ineffective separation of coarse and fine particles, but the screening speed will also be greatly reduced, requiring frequent manual cleaning of the screen. Secondly, after the screening is completed, some powder particles will remain on the surface of the screen. These powder particles are not easy to clean up and will react with the screen if they adhere to the screen surface for a long time. This is not only not conducive to the screening operation, but also affects the quality of the guar gum powder. Summary of the Invention

[0004] In view of this, the present invention provides a guar gum powder fine screening device, wherein filter holes are evenly opened on the lower end surface of the filter cylinder, and preliminary screening of the powder is started. The powder after preliminary screening by the filter cylinder will fall on the filter plate. The main body of the filter plate is a semicircular structure, which can perform secondary screening on the powder. The finer powder that meets the requirements will continue to fall through the filter plate and finally converge to the first discharge pipe through the funnel-shaped structure at the lower end of the screening box. In addition, the nozzle is inclined, and a part of the nozzle on the surface of the second air pipe is inclined upward, and the gas is blown to the filter cylinder above, and the other part is inclined downward, and the gas is blown to the filter plate below. The ejected gas can be used to jet and clean the filter cylinder, filter plate and other parts to prevent the guar gum powder from accumulating and clogging in these parts, thereby ensuring the smooth progress of subsequent screening work.

[0031] Specific usage and function of this embodiment: In the present invention, guar gum powder enters the filter cartridge 2 through the feed pipe 201. The lower end surface of the filter cartridge 2 is evenly provided with filter holes. In this process, the powder begins to undergo preliminary screening. Guar gum powder with smaller particles can pass through the filter holes and fall down, while powder with larger particles and not meeting the required size remains in the filter cartridge 2. The powder after preliminary screening by the filter cartridge 2 will fall on the filter plate 104. The main body of the filter plate 104 is a semicircular structure, which can perform secondary screening on the powder. The finer powder that meets the requirements will pass through the filter plate 104 and continue to fall, and finally converge to the first discharge pipe 102 through the funnel-shaped structure at the lower end of the screening box 1. In this process The worker can start the drive motor 3, and the drive motor 3 can drive the drive shaft 301 to rotate. The two active bevel gears 3011 installed on the surface of the drive shaft 301 respectively mesh with the passive bevel gear 401 at the right end of the connecting shaft 4, thereby driving the connecting shaft 4 to rotate. The outer end surface of the connecting shaft 4 is fixedly installed with blades 402 with a spiral structure. The blades 402 at the upper position fit against the inner wall of the filter cartridge 2, and the blades 402 at the lower position fit against the inner wall of the filter plate 104. When the blades 402 rotate, the blades 402 at the upper end can stir the larger particles of powder in the filter cartridge 2 to prevent them from accumulating and clogging the filter holes, and can also push the larger particles of powder remaining in the filter cartridge 2 to the third outlet The material pipe 202 moves so that it can be discharged through the third discharge pipe 202. For the powder falling on the filter plate 104, the rotation of the lower blade 402 can also assist in its further screening and movement. The second discharge pipe 103 and the third discharge pipe 202 are arranged in an inclined structure, which is convenient for the powder to be discharged smoothly by gravity. The plug plate 5 is clamped at the outlet end of the first discharge pipe 102, and the pressure sensor 601 is fixedly installed on the upper end face of the plug plate 5. When the powder at the first discharge pipe 102 accumulates to a certain extent, it generates pressure on the plug plate 5, and the pressure reaches the set threshold of the pressure sensor 601, the pressure sensor 601 will transmit the signal to the controller 6, and the controller 6 will then control the alarm 7 to sound. The alarm reminds the staff to deal with the powder inside the first discharge pipe 102 in time. After the screening is completed, some powder will remain inside the screening box 1 and the filter cylinder 2. At this time, the first air pipe 8 is connected to the air pump, and the gas enters the second air pipe 801 through the first air pipe 8 and is sprayed out from the nozzle 8011. The nozzle 8011 is inclined. Part of the nozzle 8011 on the surface of the second air pipe 801 is inclined upward, and the gas is blown to the filter cylinder 2 above, and the other part is inclined downward, and the gas is blown to the filter plate 104 below. The sprayed gas can be used to clean the filter cylinder 2, the filter plate 104 and other parts to prevent guar gum powder from accumulating and clogging in these parts, thereby ensuring the smooth progress of subsequent screening work.
