Wet-method dust removal device for powder grinding machine

Abstract

The invention belongs to the field of molding powder processing dust removal, and particularly relates to a wet-method dust removal device for a powder grinding machine. The wet-method dust removal device comprises one or more draught fans and dust guide pipes, wherein the draught fan is provided with dust discharging pipes and is communicated with the dust guide pipes by virtue of the dust discharging pipes, an opening of each dust discharging pipe is formed in the inner side of the corresponding dust guide pipe, the openings in all the dust discharging pipes are consistent in direction, and each opening is away from a starting end and is provided with a check valve for preventing dust from returning into the corresponding dust discharging pipe; the tail end of each dust guide pipe faces downwards, a collection tank with water is arranged right below the dust guide pipes, the tail end of each dust guide pipe is connected with dust filter cloth of a tubular structure, the upper end of the dust filter cloth is provided with a water sprayer, the lower end of the dust filter cloth stretches to be below the water surface in the collection tank, the collection tank is connected with one or more precipitation tanks, and a water pump is arranged in the last precipitation tank and is connected to the water sprayer by virtue of a water pipe. The wet-method dust removal device is simple in structure and has advantages of low cost, good dust removal effect, capability of recycling dust, environmental protection, energy conservation and the like.

Description

technical field [0001] The invention belongs to the field of dust removal for plastic powder processing, and in particular relates to a wet dust removal device for a pulverizer, which is specially used for removing dust containing organic polymers such as resins. Background technique [0002] With the rapid development of modern industrial technology, plastic powder processing technology and products are changing with each passing day. More and more plastic powder products have been widely used in various fields of people's lives, which has brought convenience to people, but also brought many disadvantages. , For example, in the process of plastic powder processing, especially when the mill is milling, a lot of powder particles will be produced. The powder particles produced by the mill will pass through the cyclone separator and the filter of the dust box, and there will still be some Powdery particles cannot be collected. These powdery particles are easy to float in the wo...

AI Technical Summary

Problems solved by technology

Do not damage the first layer when cleaning the dust, so as not to reduce the efficiency, and the dust removal effect of the bag filter is not good, and the powder recovery is also very difficult

[0004] There are also some dust removal equipment on the market that can remove dust from inorganic material powders, such as the announcement number: CN 102343192 B, "wet dust collector". The uniform water mist curtain wets the dust to achieve the dust removal effect. It is difficult to thoroughly wet the dust with this method, and the wetted dust is also easily sputtered by the force of the rapid airflow, and the removed dust is also It is difficult to recycle, and the production cost of the dust collector is relatively high. To increase the airflow rapidly, a large-power fan must be used, and a high-power fan is also extremely energy-consuming
