Description

Technical Field

[0001] The utility model relates to the technical field of polyacrylamide production, in particular to a polyacrylamide feeding funnel. Background Art

[0002] Polyacrylamide is a linear high molecular polymer, which is a hard glassy solid at room temperature. Its products include glue liquid, latex and white powder. It has been widely used in drilling, acidizing, fracturing, water plugging, cementing, secondary oil recovery and tertiary oil recovery. The polyacrylamide kettle polymerization process is the mainstream process for producing dry powder polyacrylamide on the market. After the polymerization reaction, polyacrylamide colloid with a water content of 60%-80% is obtained. After the first granulation, it is sent to the drying equipment for continuous drying, and then it is crushed and screened for the second time to obtain the dry powder product with the target particle size.

[0003] During the processing of polyacrylamide, it is also necessary to add materials according to production needs. At present, the commonly used methods of adding polyacrylamide are manually pouring a small amount multiple times and throwing it multiple times with the help of small tools. The manual pouring method of adding a small amount multiple times is limited by human operation, which can easily lead to uneven addition of materials, insufficient dissolution, and thus the formation of lumps. Therefore, we propose a new polyacrylamide feeding funnel. Utility Model Content

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. By setting a stirring component, a scraper, an inclined scraper, a control valve, etc., when adding materials during the production process, first place the polyacrylamide raw material into the inner cavity of the funnel body through the feed trough, start the motor to drive the rotating shaft to rotate, so that the stirring blades rotate in the inner cavity of the funnel body, thereby stirring the polyacrylamide raw material to prevent the polyacrylamide raw material from condensing into blocks. At the same time, the scraper and the inclined scraper are driven by the rotating shaft and the stirring blades to scrape along the side wall of the inner cavity of the funnel body and the bottom inclined side wall respectively to prevent the polyacrylamide raw material from adhering to the inner cavity wall of the funnel body, and quantitative feeding is performed through the control valve.

When feeding work is performed in the production process, the polyacrylamide raw material is first placed into the inner cavity of the funnel body 1 through the feeding trough 11, and the motor 3.1 is started to drive the rotating shaft 3.2 to rotate, so that the stirring blade 3.4 rotates in the inner cavity of the funnel body 1, thereby stirring the polyacrylamide raw material to prevent the polyacrylamide raw material from condensing into blocks. A discharge port 4 is fixedly connected to the bottom of the funnel body 1, and a control valve 5 is provided on the discharge port 4. When adding materials, precise quantitative addition can be performed through the control valve 5. A feed trough 11 is fixedly connected to the upper part of the side wall of the funnel body 1, and the polyacrylamide raw material can be added into the inner cavity of the funnel body 1 through the feed trough 11.

[0021] Specifically, Figure 1 As shown, a cover plate 12 is snap-fitted to the top of the feed trough 11, and a handle 13 is fixedly connected to the top of the cover plate 12. By snapping the cover plate 12 on the feed trough 11, the feed trough 11 can be shielded to prevent debris from falling into the inner cavity of the funnel body 1 and affecting the quality of the polyacrylamide product.

[0022] Specifically, Figure 2 , Figure 3 As shown, a plurality of through holes 10 are evenly opened on one side of the stirring blade 3.4. When the water content of the polyacrylamide raw material is relatively high, the through holes 10 can effectively reduce the resistance of the stirring blade 3.4 when it rotates, thereby improving the stirring efficiency.
