Description

Technical Field

[0001] The utility model relates to the relevant field of screening drums, in particular to a ceramsite proppant screening drum. Background Art

[0002] Proppant refers to natural sand or artificial high-strength ceramic particles with a certain particle size and grading. Ceramic granulate proppants are made from bauxite through powder granulation and sintering. They have the characteristics of high temperature resistance, high pressure resistance, corrosion resistance, high strength, high conductivity, low density, and low breakage rate. They are key materials for fracturing construction. During the production process of ceramic granulate proppants, screening drums are required to screen out raw material particles that do not meet the particle size specifications to ensure the quality of the final product.

[0003] Existing patent application number: CN202221214361.2 A ceramsite proppant screening drum includes a feed barrel. The utility model is equipped with an electric telescopic rod. The extension of the electric telescopic rod drives the support frame on the top to tilt upward, so that the feed barrel is higher than the output barrel. The support frame on the outside of the output barrel is connected through a second support seat, which is convenient for the user to adjust the angle of the device so that the material can slide from the feed barrel into the output barrel, and the user can control the material screening speed according to the inclination angle of the adjustment device.

[0004] The above patent records a technical solution of using a screening drum to screen expanded clay proppant. The drum part of the existing screening drum is usually an integrated structure. One end of the drum part needs to be connected to the motor, and the other end is rotatably connected to the frame.

[0022] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0023] See also Figure 1 The utility model provides a ceramsite proppant screening drum, comprising a frame 1, a drum 2, a motor 3, a feed bin 4, a fine material outlet 5, a coarse material outlet 6 and a clearing device 7. The drum 2 is rotatably installed inside the frame 1, the motor 3 is installed on the left side of the frame 1, the output shaft of the motor 3 is connected to the drum 2, the feed bin 4 is arranged on the right side of the frame 1, the feed bin 4 is connected to the inner side of the drum 2, the fine material outlet 5 is arranged at the bottom of the frame 1, the coarse material outlet 6 is arranged on the left side of the frame 1, the coarse material outlet 6 is located below the motor 3, the coarse material outlet 6 is connected to the inner side of the drum 2, and the clearing device 7 is arranged on the top of the frame 1.

[0024] See also Figure 2-4In the utility model, the drum 2 is composed of a connecting frame 21 and a screen frame 22. The connecting frame 21 is installed on the inner side of the frame 1. The right end of the connecting frame 21 is rotatably connected to the frame 1, and the left end of the connecting frame 21 is connected to the output shaft of the motor 3. The connecting frame 21 is controlled by the motor 3 to rotate. The screen frame 22 is screwed on the outer side of the connecting frame 21. A screen 23 is arranged in the middle of the screen frame 22. The maintenance personnel can separate the screen frame 22 from the connecting frame 21 to dismantle and replace the screen 23 of this part. There is no need to dismantle the drum 2 as a whole from the frame 1, which greatly simplifies the dismantling operation to reduce the downtime and maintenance time of the equipment.

[0025] To further explain, a positioning hole 24 is opened on the left side of the connecting frame 21, and a latch member 25 is installed on the left side of the frame 1. The latch member 25 is located above the motor 3. The latch member 25 can be plugged into the inner side of the positioning hole 24 to position the connecting frame 21 and stop it, making it convenient to dismantle and repair the screen frame 22.

[0026] To further explain, the number of the positioning holes 24 is the same as that of the screen frames 22. When the latch 25 is inserted into the positioning hole 24, the screen frame 22 corresponding to the positioning hole 24 is located outside the frame 1, so that the screen frame 22 to be dismantled will not be blocked by the frame 1, thereby facilitating the dismantling operation.

[0027] See also Figure 5 The blockage clearing device 7 in the utility model comprises a turning frame 71 and a roller brush 72 . The turning frame 71 is hingedly mounted on the front of the top end of the frame 1 . The roller brush 72 is rotatably mounted on the end of the turning frame 71 . The roller brush 72 is used to clear the screen 23 .

[0028] It is further explained that the flipping angle of the flip frame 71 is not less than 180 degrees. After the flip frame 71 is flipped down, the roller brush 72 can be pressed on the surface of the drum 2, and the roller brush 72 can clean the drum 2 as it rotates. When not in use, the flip frame 71 can be flipped upward and placed on the top of the frame 1, which is very convenient to use and store.

[0029] It is further explained that the length of the roller brush 72 is not less than the length of the screen 23, so that the cleaning range of the roller brush 72 completely covers the screen 23, thereby ensuring the clearing effect.

[0030] To further explain, a counterweight 73 is screwed onto the connecting beam on the inner side of the flip frame 71. When the flip frame 71 is flipped down, the counterweight 73 is located directly above the roller brush 72. The counterweight 73 can apply weight to the roller brush 72, so that the roller brush 72 is tightly pressed against the surface of the drum 2, thereby improving the blockage clearing effect.

[0031] Here’s how it works:

[0032] First, the frame 1 is placed stably to ensure that it does not shake during operation, and then the circuit of the motor 3 is connected to the external control box for easy control and management.

[0033] Second, in the production process of expanded clay proppant, raw material particles that do not meet the particle size specifications need to be screened out. The specific screening process is: first, the raw material particles are added to the feed bin 4, and the raw material particles enter the drum 2 through the feed bin 4. At this time, the motor 3 is energized to drive the drum 2 to rotate, so that the raw material particles are turned over and moved in the drum 2. The raw material particles with small particle sizes will be screened out by the screen 23 and discharged downward from the fine material outlet 5, while the raw material particles with large particle sizes will remain in the drum 2 and finally be discharged outward through the coarse material outlet 6, thereby completing the raw material particle sorting process.

[0034] Third, during operation, the screen 23 in the drum 2 may be stuck by particles and cause blockage. At this time, the flip frame 71 can be flipped forward until the roller brush 72 is pressed on the surface of the drum 2. In addition, the counterweight block 73 on the flip frame 71 can apply weight to the roller brush 72, so that the roller brush 72 is tightly pressed on the surface of the drum 2 to clean the screen 23. There is no need to stop the machine to clear the blockage, thereby improving the processing efficiency. When the clearing device 7 is not in use, the flip frame 71 can be flipped upward and placed on the top of the frame 1 to complete the storage. It is very convenient to use and store.

[0035] Fourth, when the screen 23 is severely worn and needs to be repaired and replaced, first insert the latch 25 into the positioning hole 24 to keep the connecting frame 21 stable and prevent it from rotating on its own during the repair process. Then, unscrew the screws to remove the screen frame 22 from the connecting frame 21, so that the drum 2 can be partially repaired without removing the drum 2 as a whole from the frame 1, which greatly simplifies the repair operation and reduces the downtime of the equipment for maintenance.

[0036] The utility model provides a ceramsite proppant screening drum. By arranging a connecting frame 21 and a mesh frame 22, when the screen 23 is severely worn and needs to be dismantled and replaced, firstly, the latch member 25 is inserted into the positioning hole 24 to keep the connecting frame 21 stable, and then the screws are unscrewed to remove the mesh frame 22 from the connecting frame 21, so that the drum 2 can be partially dismantled and repaired without removing the drum 2 as a whole from the frame 1, which greatly simplifies the dismantling and repairing operation to reduce the downtime of the equipment for maintenance. By arranging a clearing device 7 on the top of the frame 1, the turning frame 71 is turned down forward until the roller brush 72 is pressed on the surface of the drum 2. In addition, the counterweight block 73 on the turning frame 71 can apply weight to the roller brush 72, so that the roller brush 72 is tightly pressed on the surface of the drum 2 to clean the screen 23, and there is no need to stop the machine for clearing the blockage, thereby improving the processing efficiency.
