Problems solved by technology

[0003] In the production process of green silicon carbide micropowder, it needs to be cleaned with a lot of water at the end. The traditional cleaning method is to add water to a large barrel-shaped tank, stir until it is completely suspended, and then let it stand for 8 hours. The silicon carbide particles are almost It is completely deposited in the lower part of the tank, drain the waste liquid on the upper layer, and repeat cleaning with water for 5-6 times. The consumption of clean water in this way is very large. Generally, it takes 20 tons of clean water to wash one ton of silicon carbide micropowder, which is not only It consumes a lot of water resources, increases the production cost of the enterprise, and at the same time, it is difficult to treat the waste water of the enterprise

Embodiment 1

[0031] Such as figure 1 and figure 2 As shown, a silicon carbide micropowder cleaning device includes 7 cleaning liquid pools 1 made of cement and arranged in a row, 9 cleaning tanks 2 with electric stirring shafts, and a circulation system arranged on one side of the cleaning liquid pool 1. Track 5, each of the cleaning liquid pools 1 is provided with a cleaning liquid pump 4, the bottom of the cleaning tank 2 is fixed with a movable part 3, and the movable part 3 is placed in the circulating track 5, and the circulating track 5 There is a limit groove 6 for the positioning of the cleaning tank 2. The upper end of the cleaning tank 2 introduces the upper waste liquid into the cleaning liquid pool 1 through the waste liquid pipe 7. The outer side of the circulation track 5 is provided with a feeding point 8 and Finished product unloading point 9.

[0032] This kind of device, according to the number of the cleaning liquid pool 1, can adjust the size of the circulation track...

Embodiment 2

[0034] Such as image 3 As shown, a water-saving device cleaning method for silicon carbide micropowder cleaning, taking 7 cycles as an example, the direction is according to image 3 Middle arrows cycle from left to right:

[0035] When using 7 times of repeated cleaning, there are 7 cleaning liquid pools and 9 stirring cleaning tanks. The specific operations are as follows:

[0036] The first cleaning: put the cleaning tank 2 with a volume of 5m³ on the circulation track 5, add 1 ton of powder to be cleaned at the feeding point 3, move the cleaning tank 2 to the fixed position at the limit groove 6a, and clean the liquid The pump 4f pumps the cleaning liquid in the cleaning liquid pool 1f into the cleaning tank 2. The amount of the cleaning liquid is 4m3. After being fully stirred until it is completely suspended, it is left to stand for 8 hours, and then the upper layer liquid is put into the cleaning liquid pool from the waste liquid pipe 7g. 1g, the cleanliness of the p...

Embodiment 3

[0043] Take 9 cycles as an example: when using 9 repeated cleanings, there are 9 cleaning liquid pools and 11 stirring cleaning tanks, and the specific implementation of the cycle process is the same as in Example 2.

[0044] Compared with Example 2, the cleanliness of the finished product after cleaning is significantly improved compared with the 7-time cleaning method, and the consumption of fresh water is the same, but the cleaning cycle will be extended by 28.5% (2 / 7×100%).

Abstract

The invention discloses a device and method for cleaning silicon carbide micro-powder. The device comprises a plurality of cleaning fluid pools, a plurality of cleaning tanks and a circulating rail arranged on one sides of the cleaning fluid pools; each cleaning fluid pool is provided with a cleaning solution pump, movable parts are fixedly arranged at the bottoms of the cleaning tanks, the movable parts are arranged in the circulating rail, limiting grooves used for positioning the cleaning tanks are formed in the circulating rail, the upper ends of the cleaning tanks are introduced into thecleaning fluid pools through waste liquid pipes, and a feeding point and a finished product discharging point are arranged on the outer side of the circulating rail. The water-saving device is reasonable in structural design and high in practicability; the water-saving device is used for cleaning the silicon carbide micro-powder, so that the problems of water resource waste and enterprise treatment waste water can be solved, and meanwhile the product quality is guaranteed, and the device is worthy of popularization and use.

Description

technical field [0001] The invention relates to a cleaning method, in particular to a silicon carbide micropowder cleaning device and a cleaning method thereof. Background technique [0002] Today, as ecological and environmental protection is becoming more and more stringent, water conservation is a problem that every enterprise must pay attention to. Because water conservation can not only reduce production costs, but also reduce the difficulty of wastewater treatment, so whether water conservation can be realized will be the future of the enterprise. Can the node process survive. [0003] In the production process of green silicon carbide micropowder, it needs to be cleaned with a lot of water at the end. The traditional cleaning method is to add water to a large barrel-shaped tank, stir until it is completely suspended, and then let it stand for 8 hours. The silicon carbide particles are almost It is completely deposited in the lower part of the tank, drain the waste li...
