Description

Dust recovery system of humate drying and separating device

Technical Field

The utility model relates to a dust recovery system especially relates to a humate mummification separator's dust recovery system.

Background

In the drying process of preparing the humate, the humate on the drying cylinder needs to be scraped by a scraper, and when the scraper rubs with the drying cylinder, a part of the humate is changed into fine powder, and the fine powder is scattered or suspended on a production site like dust, so that the air environment is greatly polluted, the human health is greatly damaged, and the humate drifts and adheres to equipment, so that the stable operation of the equipment is also influenced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a dust recovery system of a humate drying and separating device, which solves the problems existing in the prior art.

This recovery system includes: set up in the suction hood of a plurality of drying-machines top, set up in the dust absorption house steward on suction hood upper portion, with the spray column that the dust absorption house steward is connected, for each dust absorption pipeline provides the fan of negative pressure, wherein, the dust absorption house steward passes through the lower part intercommunication of collecting pipe and spray column, and the pipe diameter that the dust absorption house steward is close collecting pipe intercommunication department is the biggest, along with the dust absorption house steward to each suction hood direction extension of keeping away from collecting pipe intercommunication department, its pipe diameter diminishes gradually, guarantees that each suction hood is unanimous to the vacuum adsorption power of drying-machine.

Furthermore, each dust hood is communicated with the dust collection main pipe above the dust hood through three dust collection pipes.

Further, the fan is communicated with the top of the spray tower through a negative pressure pipe.

Furthermore, a plurality of spray headers are arranged at the upper part of the spray tower, and the spray headers are uniformly distributed at the upper layer and spray water mist downwards.

Further, an ascending air channel with a larger diameter at the top and a smaller diameter at the bottom is arranged below each spray header.

Furthermore, the lower part of the ascending air passage is provided with a tapered hole, and the tapered hole is opened, closed or used for adjusting the ventilation flow through an adjustable tapered plug which moves up and down.

Further, a liquid discharge pipe is arranged at the bottom of the spray tower.

The technical effects of the utility model reside in that: the dust hood is arranged above each dryer and connected through a dust collection main pipe, dust generated by each dryer is sent into the spray tower together, the diameter of the dust collection main pipe is adjusted according to the position of the dust hood, and the negative pressure generated by the fan can be uniformly distributed to the dust collection main pipe section above each dust hood. The ascending air channel in the spray tower is aligned with the lower part of the spray header, and the ascending air channel is of a structure with a large upper part and a small lower part, so that dust in the air and sprayed water mist are easily combined with each other. The adjustable conical plug can be used for the air flow of a single ascending air channel and can also control the air flow of the whole adsorption pipeline. When the workshop dust is great, increase the air flow, promote the negative pressure adsorption affinity, collected more dust through the dust absorption pipeline, the dust of collecting mixes the back with water, directly sells as humate solution product, avoids environmental pollution and waste because of the dust causes.

Detailed Description

The following describes embodiments of the present invention with reference to fig. 1 to 3.

Fig. 1 and 2 show the components of a recycling system and their connections, the recycling system comprising: the vacuum dust collection device comprises dust hoods 1 arranged above a plurality of dryers, a dust collection header pipe 2 arranged at the upper part of the dust hoods 1, a spray tower 3 connected with the dust collection header pipe 2, and a fan 4 for providing negative pressure for each dust collection pipeline, wherein the dust collection header pipe 2 is communicated with the lower part of the spray tower 3 through a collecting pipe 5, the pipe diameter of the part, close to the communication part of the collecting pipe 5, of the dust collection header pipe 2 is the largest, the pipe diameter of the dust collection header pipe 2 gradually decreases along with the extension of the dust collection header pipe 2 to the direction of each dust hood 1 far away from the communication part of the collecting pipe 5, the vacuum adsorption force of each dust hood 1 to the dryers is ensured to be consistent, and each dust hood 1 is communicated with the dust collection header pipe 2 above through three dust collection pipes 11; the fan 4 is communicated with the top of the spray tower 3 through a negative pressure pipe 6.

Fig. 3 illustrates the structure inside the spray tower, and the spray tower 3 is provided with a spray header 31 at the upper part; an ascending air channel 32 with a large diameter at the top and a small diameter at the bottom is arranged below each spray header 31; the lower part of the ascending air channel 32 is provided with a tapered hole, and the tapered hole opens, closes or adjusts the ventilation flow through an adjustable tapered plug 33 which moves up and down; the bottom of the spray tower 3 is provided with a liquid discharge pipe 34.
