Description

Technical Field

[0001] This utility model relates to the field of ceramic proppant granulation technology, specifically a non-sintering ceramic proppant granulation device. Background Technology

[0002] With the rapid development of the petroleum 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 is also increasing. The high strength of proppant itself comes not only from the raw materials themselves, but also from the finished product properties, pore distribution, pore size and density. Pelletizers play an extremely important role in the production of proppant.

[0003] The announcement number is CN217663181U, which discloses "a granulation device for ceramic proppant, including a bottom box and an auxiliary drying device";

[0004] There are still some drawbacks in its use. The powder is squeezed by the rotation of the pressure roller, and the ceramsite support is forced to pass through the sieve plate to achieve granulation. Granulation can only be carried out through the sieve plate set at the bottom. The granulation area is limited, resulting in a slow granulation rate. In addition, the powder can easily leak out through the holes of the sieve plate, making it difficult to separate the ceramsite and the powder. Utility Model Content

[0005] The purpose of this invention is to provide a non-sintering ceramic support granulation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A non-sintering ceramic aggregate support granulation device, comprising:

[0008] A collection chamber, wherein a filter screen is installed at the lower end of the collection chamber;

[0009] The first granulation component is located inside the collection chamber. The first granulation component includes a granulation chamber fixedly installed on the inner surface of the collection chamber. Multiple holes are equally spaced on the outer surface of the granulation chamber. A sieve plate is fixedly installed at the lower end of the granulation chamber.

[0010] The second granulation component is located outside the granulation chamber. The second granulation component includes a first ring rotatably connected inside the granulation chamber, and a second ring rotatably connected outside the granulation chamber.

[0011] Furthermore, a material hopper is provided on one side of the collection hopper, a spiral feeding pipe is provided inside the material hopper, a discharge pipe is fixedly installed at the lower end of the outer surface of the collection hopper, and a guide pipe is fixedly installed at the lower end of the collection hopper, and the guide pipe is fixedly connected to the material hopper.

[0012] Furthermore, a support frame is fixedly installed at the upper end of the collection bin, a rotating shaft is rotatably connected inside the support frame, and a pressure roller is fixedly installed at the lower end of the rotating shaft.

[0013] Preferably, a connecting frame is symmetrically fixedly installed on the outer surface of the rotating shaft, and a rotating roller is rotatably connected to one end of the connecting frame. A U-shaped frame is fixedly installed on the upper end of the first and second rings, and the U-shaped frame is fixedly connected to the rotating shaft through a support rod.

[0014] Preferably, a motor is fixedly mounted on the upper end of the support frame via a bracket, and two meshing gears are fixedly mounted on the output end of the motor and the upper end of the rotating shaft.

[0015] Furthermore, two feed slots are equidistantly provided on the outer surface of the first ring, two discharge slots are equidistantly provided on the outer surface of the second ring, and two air chambers are fixedly embedded and installed equidistantly on the inner surface of the first ring.

[0016] Preferably, a three-way air pipe is fixedly installed at the upper end of each of the two air chambers, the upper end of the three-way air pipe is fixedly inserted through the upper end of the rotating shaft, and a rotary joint is fixedly installed at the upper end of the three-way air pipe.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The motor drives the rotating shaft to rotate the pressure roller, which works in conjunction with the screen plate to granulate the ceramsite. The ceramsite falls from the screen plate onto the filter screen surface. The first ring, the second ring, and the rotating roller rotate with the rotating shaft. The rotating roller squeezes the powder inside the feed trough, causing the powder to be squeezed into granules inside the holes. The air pump pressurizes the air chamber, pushing the ceramsite inside the holes out of the discharge trough and then falling onto the filter screen before being discharged. Thus, by opening holes in the outer wall of the granulation chamber, the rotating roller rotates with the rotating shaft, squeezing the powder into the holes for granulation, increasing the granulation area and accelerating the granulation speed.

[0019] 2. Powder is poured into the hopper, and the filtered powder passes through the filter screen and is discharged into the hopper. The spiral feeding pipe rotates and injects powder from the top of the granulation hopper, so that when the ceramsite is discharged, the powder carried on the surface of the ceramsite is separated from the ceramsite and the powder can be recycled.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 In this embodiment of the present invention, a non-sintering ceramsite support granulation device includes a collection chamber 1. A filter screen 103 is provided at the lower end of the collection chamber 1. The filter screen 103 is placed obliquely so that the ceramsite can be discharged along the filter screen 103 to the discharge pipe 101, while the powder passes through the filter screen 103 and falls into the guide pipe 102. A first granulation component 2 is provided inside the collection chamber 1. The first granulation component 2 includes a granulation chamber 201 fixedly installed on the inner surface of the collection chamber 1. A plurality of holes 207 are equidistantly opened on the outer surface of the granulation chamber 201. A sieve plate 202 is fixedly installed at the lower end of the granulation chamber 201. A second granulation component 3 is provided outside the granulation chamber 201. The second granulation component 3 includes a first ring 301 rotatably connected inside the granulation chamber 201, and a second ring 302 rotatably connected to the outer side of the granulation chamber 201.

[0028] Specifically, granulation component 2 operates to extrude granules from the bottom of the powder, while granulation component 3 operates to extrude granules from the periphery of the powder, increasing the granulation range.

[0029] Example 1

[0030] like Figure 2 and Figure 5 As shown, in this embodiment, a support frame 104 is fixedly installed on the upper end of the collection bin 1, and a rotating shaft 203 is rotatably connected inside the support frame 104. A pressure roller 204 is fixedly installed on the lower end of the rotating shaft 203. A motor 205 is fixedly installed on the upper end of the support frame 104 through a bracket. Two meshing gears 206 are fixedly installed on the output end of the motor 205 and the upper end of the rotating shaft 203.

[0031] In this embodiment, the motor 205 operates, and through the transmission of the gear 206, the rotating shaft 203 rotates, driving the pressure roller 204 to rotate, which works in conjunction with the sieve plate 202 to granulate, and the ceramsite falls from the sieve plate 202 onto the surface of the filter screen 103.

[0032] like Figure 3-5 As shown, in this embodiment, connecting frames 308 are symmetrically fixedly installed on the outer surface of the rotating shaft 203. A rotating roller 309 is rotatably connected to one end of the connecting frame 308. A U-shaped frame 306 is fixedly installed on the upper ends of the first ring 301 and the second ring 302. The U-shaped frame 306 is fixedly connected to the rotating shaft 203 via a support rod. Through the connection of the U-shaped frame 306, the first ring 301 and the second ring 302 rotate simultaneously. Two feed grooves 304 are equidistantly formed on the outer surface of the first ring 301, and the outer surface of the second ring 302... Two discharge troughs 305 are equidistantly provided on the surface. The discharge troughs 305 and the air chambers 303 are located at the same angle, which facilitates the air to discharge the ceramsite from the discharge troughs 305. Two air chambers 303 are fixedly embedded in the inner surface of the first ring 301 at equal intervals. A three-way air pipe 307 is fixedly installed on the upper end of the two air chambers 303. The upper end of the three-way air pipe 307 is fixedly inserted through the upper end of the rotating shaft 203. A rotary joint is fixedly installed on the upper end of the three-way air pipe 307. One end of the rotary joint is connected to an air pump through a hose to inject air into the air chamber 303.

[0033] In practice, the first ring 301, the second ring 302, and the rotating roller 309 rotate with the rotating shaft 203. The rotating roller 309 squeezes the powder inside the feed trough 304, causing the powder to be squeezed into granules inside the holes 207. The air pump pressurizes the air chamber 303, pushing the ceramic particles inside the holes 207 out of the discharge trough 305, and then they fall above the filter screen 103 and are discharged. Thus, by opening the holes 207 on the outer wall of the granulation chamber 201, the rotating roller 309 rotates with the rotating shaft 203, squeezing the powder into the holes 207 for granulation, increasing the granulation area and accelerating the granulation speed.

[0034] Example 2

[0035] Based on Example 1, in order to address the issue of easily filtering and recovering the powder carried out by the ceramic particles.

[0036] like Figure 1As shown, in this embodiment, a material bin 105 is provided on one side of the collection bin 1, a spiral feeding pipe 106 is provided inside the material bin 105, a discharge pipe 101 is fixedly installed at the lower end of the outer surface of the collection bin 1, and a guide pipe 102 is fixedly installed at the lower end of the collection bin 1. The guide pipe 102 is fixedly connected to the material bin 105.

[0037] In practice, the powder is poured into the hopper 105, and the filtered powder passes through the filter screen 103 and is discharged into the hopper 105. The spiral feed pipe 106 rotates and injects the powder from the top of the granulation hopper 201, so that when the ceramsite is discharged, the powder carried on the surface of the ceramsite is separated from the ceramsite and the powder is recycled.
