Description

Technical Field

[0001] The utility model relates to the relevant field of granulation equipment, in particular to a granulation device for ceramsite proppant. Background Art

[0002] In recent years, with the rapid development of the world's oil industry, the difficulty of oil and natural gas extraction is gradually increasing, the depth of oil and natural gas wells is getting deeper and deeper, and there are more and more low-permeability deposits. The demand for high-strength proppant products at home and abroad is also increasing. The high strength of the proppant itself does not only come from the raw materials themselves, but also has a very close relationship with the properties of the finished product, pore distribution, pore size and density, etc., and the granulator plays an extremely important role in the production of proppant preparation;

[0003] The pellet mill is mainly composed of feeding, mixing, pelletizing, transmission and lubrication systems, etc. It is widely used in the pharmaceutical, chemical and food industries. The pellet mill can be divided into feed pellet mill and biomass energy pellet mill. The existing types of refrigerants include tablet pellet mill, extrusion pellet mill, spray pellet mill, drum pellet mill and flat mode pellet mill, etc. Among them, the flat mode pellet mill uses a roller to achieve rolling and forming pellets, which is a more common pellet mill for pelletizing;

[0004] The flat die pelletizing machine with the existing application number CN202122970969.X comprises a motorized part, a pelletizing part and a base frame, a feed port is arranged at the upper end of the pelletizing part, and the lower end of the feed port contacts with a hopper device, the hopper device comprises a hopper conveying pipe, a hopper support plate and a feed stopper, the upper end of a hopper sealing cover contacts with the feed port, the other side of the hopper sealing cover is connected with the hopper conveying pipe, a feed stopper is arranged in the hopper conveying pipe, a pressing roller device is arranged at the lower end of the feed stopper, the pressing roller device is located on a circular hole mold, a hopper support plate is arranged at the lower end of the circular hole mold, the hopper support plate can make the material fall on the hopper support plate, one side of the hopper support plate is connected with the discharge port, the motorized part comprises an engine and a main shaft, the engine is mounted on the base frame, one side of the engine is connected with a transmission shaft, the transmission shaft is connected with the main shaft, and casters are arranged at the lower end of the base frame, so as to flexibly change the processing position;

[0005] The above-mentioned existing flat die pelletizing machine realizes uniform entry of materials for crushing and granulation and reduces the occurrence of carryover by arranging a discharge rod, a feed limiter, a main shaft, an adjustment window plate, a feed window and a fan blade baffle. However, the feed window is a certain distance away from the bottom pressure roller, which makes it difficult for the material discharged from the feed window to fall evenly and completely onto the crushing and granulation track of the pressure roller, causing material leakage during the crushing and granulation of the pressure roller. At the same time, when the material is poured into the granulating cylinder, there is a lack of certain screening measures to filter large and small particles, resulting in the large particles existing in the subsequent crushing and granulation being more likely to clog the circular hole module, resulting in a significant reduction in the granulation and discharge efficiency of the material.

[0035] Here’s how it works:

[0036] When the ceramsite proppant granulation is to be carried out, the control box 3 provided at the upper end of the middle part of the bracket 1 can be used to open the motor 4 provided at the upper end of the right side of the bracket 1. In this way, the motor 4 can cooperate with the transmission structure 5 connected at the bottom to drive the rotation of the left side connected shaft 9. As the shaft 9 rotates, the four-axis pressure roller 10 connected to the upper end of the shaft 9 can rotate along the circumference of the upper end of the circular hole screen plate 8. Then, the staff pours the ceramsite proppant raw material from the feed hopper 7 to make the material fall into the granulation cylinder. 6, so that the material can be squeezed out of the circular hole sieve plate 8 in cooperation with the four-axis pressing roller 10 rotating in a circular motion, and when the material is extruded to the lower end of the circular hole sieve plate 8, the cutting knife 11 arranged on the left and right sides of the upper end of the rotating shaft 9 can be driven by the rotating shaft 9 to cut off the extruded material, thereby, the extruded material can be processed into granules, and the material guide plate 12 arranged on the left side of the granulating cylinder 6 can be used to discharge the material, so that the rapid rolling and granulation of the ceramsite proppant can be realized;

[0037] In order to ensure that the ceramsite proppant material can be evenly fed and efficiently crushed and granulated, a uniform screening and feeding device 13 is provided inside the feed hopper 7. First, after the material is poured from the feed hopper 7, it will fall onto the connecting plate 1361 provided on the screening assembly 136 in advance for screening preparation, and the convex roller 1369 connected to the upper end of the main shaft 133 can rotate synchronously with the rotating shaft 9. In this way, in conjunction with the smooth convex surface on the top of the convex roller 1369, the upper right end will be lifted against the lifting rod 1368, so that the lifting rod 1368 can realize the upward push of the connecting plate 1361 as a whole. As the connecting plate 1361 moves up and down, the connecting pipe 1365 connected to the left and right sides of the connecting plate 1361 through the locking shaft 1367 can be synchronously moved upward along the plug-in shaft 1364 plugged in the middle, and the compression of the compression spring 1366 connected to the outer side of the plug-in shaft 1364 can be realized. The body can realize stable upward movement, and after the convex roller 1369 rotates one circle and resets, the lifting effect on the lifting rod 1368 will be released, so that the compression springs 1366 connected to the outer ends of the plug-in shafts 1364 on both sides will rebound, and the connecting pipe 1365 will quickly move down and reset. In this way, the connecting plate 1361 can be reset accordingly to collide and vibrate with the supporting blocks 1363 on both sides, and then, the material received by the upper end of the connecting plate 1361 can be subjected to the vibration force and pass through the screen 1362 provided inside the connecting plate 1361 to realize convenient vibration filtering and screening activities to screen and process the large and small particles inside the material, so as to prevent large particles from affecting the subsequent rolling and granulation efficiency, and the materials that pass through the screen 1362 and meet the particle standards can evenly fall onto the supporting plate 131 to realize the pushing and positioning discharging activities, thereby achieving the advantages of automatic lifting and vibration screening of materials and realizing the separation and processing of large and small particles of materials;

[0038] When the material falls on the supporting plate 131 after screening, the pushing plate 1351 connected to the outer side of the main shaft 133 through the pin shaft 1352 can rotate synchronously with the main shaft 133 to realize the pushing of the material, and cooperate with the scraper 1353 set at the left rear end of the pushing plate 1351 to improve the sufficiency and uniformity of the material pushing. When the material is pushed to a certain material guide circular opening 132 equidistantly opened inside the supporting plate 131, the material will be positioned and fall out along the material guide circular opening 132, and cooperate with the guide cylinder 134 correspondingly installed at the lower end to realize the extended guiding cooperation, so that the material can accurately and evenly fall to the rolling center of the four sides of the four-axis pressure roller 10 to carry out efficient and sufficient rolling and granulation of the material, reduce the occurrence of material omission in rolling and granulation, thereby achieving the advantages of uniform positioning and discharging of expanded clay proppant and improving the quality and efficiency of subsequent material rolling and granulation.

[0039] The utility model provides a granulating device for ceramsite proppant, which is provided with a uniform screening feeding device 13, that is, the main shaft 133 is driven by the rotating shaft 9, and the pusher 135 connected to the outside can be rotated to push the material received by the supporting plate 131 into the inside of the material guide circular opening 132, and cooperate with the guide cylinder 134 arranged relatively at the lower end to realize the positioning and uniform discharge of the material, thereby achieving the advantages of uniform positioning and discharging of the ceramsite proppant and improving the quality and efficiency of subsequent material rolling and granulation, and a screening component 136 is provided, that is, the main shaft 133 can drive the convex roller 1369, so that the convex roller 1369 and the lifting rod 1368 are lifted by the connecting plate 1361, and the connecting plate 1361 can cooperate with the elastic force of the compression springs 1366 arranged at both ends to perform a rapid reset activity, so that the connecting plate 1361 can reciprocate and vibrate to make the material quickly pass through the screen 1362, and perform auxiliary screening processing cooperation, thereby achieving the advantages of automatic lifting and vibration screening of the material, and realizing the separation and processing of large and small particles of the material.
