AI Technical Summary

Problems solved by technology

This structure has the following deficiencies in the batching device: 1. The compressed gas is blown into the pit from the lower end, and then the material is blown away. The operation route of the compressed gas is complicated, resulting in pressure loss; Generate a lot of noise; 3. The uneven distribution of the dry ice delivery pits set on the dry ice delivery shaft will cause uneven ingredients

Embodiment 1

[0034] Such as figure 1 , figure 2 and image 3 Shown is the dosing device of the particle spraying equipment disclosed in the present invention, including a box body 1 and a dosing shaft 2, in this embodiment, as Figure 4 , Figure 5 and Figure 7 As shown, the box body includes a base 11, two support plates 12, an upper sealing block 13 and a lower sealing block 14, and the two support plates 12 are respectively fixed to the two ends of the base 11, specifically, the support plate 12 are respectively limited on the base by pins 73 and fixed by fastening bolts 74, the lower sealing block 14 is placed between the two support plates 12 and installed on the base 11, the upper sealing block The block 13 is placed on the upper part of the lower sealing block 14 and is fixedly connected with the two support plates 12, such as Figure 8 and Figure 9As shown, the upper sealing block 13 has an upper batching shaft installation cavity 131, and the lower sealing block 14 has a ...

Embodiment 2

[0042] Such as Figure 13 and Figure 14 Shown is the second embodiment of the batching device of the particle spraying equipment disclosed in the present invention. The difference between this embodiment and Embodiment 1 is that, in Embodiment 1, the batching groove 20 on the batching shaft 2 and the batching shaft The axes are parallel, and in Embodiment 2, the batching groove 20 forms a certain angle with the axis of the batching rotating shaft 2 .

[0043] Such as Figure 15 Shown is the motion analysis diagram (plan view) when the material reaches the air inlet with the rotation of the batching shaft in the batching groove in embodiment 1. The material rotates together with the batching shaft in the batching groove. When the material just When reaching the air inlet, the material has a horizontal velocity V1, and the batching shaft has a horizontal speed V3, V1=V3. With the rotation of the batching shaft, the batching groove moves in a circular motion, and the material ...

Abstract

The invention discloses a batching device of particle spraying equipment, which comprises a box body and a batching shaft. The box body has a batching shaft installation cavity, and the batching shaft is installed in the batching shaft installation cavity and can rotate relative thereto. The outer surface of the batching shaft is airtightly matched with the inner surface of the installation cavity of the batching shaft. There is a feeding port on the box, and a mixing chamber is provided in the installation cavity of the batching shaft. The mixing chamber is on the box. There are air inlets and air outlets at both ends of the feeder shaft, and a plurality of batching grooves are uniformly arranged on the outer circumference of the batching shaft. When the batching shaft rotates, the batching grooves can communicate with the inlet. Air port and air outlet. The device has the advantages of wear resistance, uniform batching, adjustable particle flow and good air tightness.

Description

technical field [0001] The invention relates to the field of material transportation, in particular to a batching device of particle spraying equipment. Background technique [0002] Particle blasting equipment is widely used in sand blasting (shot blasting) equipment, cleaning equipment (dry ice cleaning, ice particle cleaning) and surface treatment equipment. The principle is to feed compressed gas into the particle blasting equipment, and the compressed gas will be sprayed The material is ejected at high speed to complete its working process. [0003] The main part of the particle injection equipment is the batching device. The function of the batching device is to transport the material to be injected from the feed port to the mixing chamber, and complete the mixing of the material and compressed gas in the mixing chamber for injection. [0004] In Chinese utility model patent: 200720155793.X, patent name: single-pipe dry ice blasting machine, a batching device for dry ...
