Description

Technical Field

[0001] The utility model relates to the technical field of ceramsite proppant production, in particular to a ceramsite proppant semi-finished product screening and recycling device. Background Art

[0002] Ceramic granule proppant is a ceramic granule product made from bauxite through a specific production process. It has the characteristics of high temperature resistance, corrosion resistance, high pressure resistance, high strength, high conductivity, low density and low breakage rate. The production process of ceramsite proppant is a complex and delicate process, from the selection, crushing, grinding, granulation, calcination of raw materials to the final product formation, and the semi-finished product is a stage product in the process. It is a material that needs further processing or waiting for subsequent process steps after a certain process step is completed. The sieved ceramsite proppant semi-finished product can be reused according to its particle size. Ceramic granules with larger particle sizes can be used in occasions that require greater support, while ceramsites with smaller particle sizes can be used for other applications with smaller requirements. This recycling method not only improves the utilization efficiency of resources, but also reduces production costs.

[0003] After searching, a Chinese patent with publication number CN214515264U discloses a device for screening semi-finished ceramsite proppants. Since there is no control over the amount of ceramsite proppants falling, the discharge port of the box is often blocked, thereby affecting the screening efficiency. Therefore, when the falling height reaches a predetermined value, the first motor and the third motor are started, and the first motor drives the rotating rod to rotate to ensure the falling of material particles; the third motor folds the flexible cloth through the pull rope, so that the particles fall onto the filter screen for step-by-step screening, thereby achieving the purpose of quantitative falling and preventing the discharge port from being blocked.

[0004] There are still some shortcomings in the use of the above-mentioned screening device. When the above-mentioned expanded clay proppant semi-finished product is screened, the screen plate is tilted and stationary. Although there is a screening function, the screening effect is relatively weak. It is not convenient for the screen plate to shake during screening to accelerate material discharge, which makes it easy for a large amount of material to accumulate on the screen plate and difficult to discharge, resulting in blockage of the screen plate, thereby affecting the screening efficiency and speed and prolonging the screening time.

[0032] A feeding pipe 14 is fixedly connected to the top of the screening frame 1 for feeding materials. A mounting frame 15 is fixedly connected to the top of the front side of the screening frame 1. A second motor 16 is fixedly installed at the bottom end of the mounting frame 15.

[0033] Working principle: When the semi-finished ceramsite proppant is screened, the first motor 3 is started, so that the first motor 3 drives the synchronous wheel 1 4 to rotate. Under the action of the synchronous belt 13, the synchronous wheel 1 4 drives the synchronous wheel 2 6 to rotate, and then the synchronous wheel 2 6 drives the eccentric wheel 7 to rotate. When the eccentric wheel 7 rotates, it drives the connecting rod 8 to rotate and is pushed, thereby moving left and right. Then, when the connecting rod 8 rotates, it rotates and pushes the connecting block 9. Under the action of the spring 11 pushing the pushing block 12, the pushing block 12 pushes the sieve plate 2 to move left and right under the action of elastic force, so that the sieve plate 2 can be shaken and screened left and right. There is no need to manually shake the sieve plate 2, which is beneficial to improving the screening effect, thereby facilitating the accelerated discharge of materials on the sieve plate 2, and reducing the phenomenon of clogging of the sieve holes due to material accumulation on the sieve plate 2, thereby improving the screening efficiency and speed and shortening the screening time. When the material is put into the screening frame 1, the second motor 16 is started first, so that the second motor 16 drives the rotating rod 17 to rotate, so that the rotating rod 17 drives the gear 18 to rotate, and due to the effect of the tooth block in the gear 18, the gear 18 rotates and drives the fixed block 21 to swing back and forth, so that the fixed block 21 drives the right-side knocking hammer 20 to swing back and forth and perform a knocking action. When the right-side knocking hammer 20 rotates, it drives the connecting rod 19 to rotate, so that the connecting rod 19 drives the left-side knocking hammer 20 to perform a knocking action, thereby increasing the knocking force, thereby knocking the struck block 22, so that the struck block 22 transmits the vibration force generated by the knocking to the feeding pipe 14, thereby facilitating material feeding, reducing the blockage at the feed pipe mouth caused by feeding a large amount of material together, thereby slowing down the feeding speed, and is conducive to improving the feeding efficiency, thereby improving the production efficiency.
