Description

Technical Field

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

[0002] Polyacrylamide is a hard glassy solid at room temperature. Its products include liquid glue, latex, white powder, translucent beads and flakes. It has good thermal stability. Polyacrylamide is widely used in many fields as a lubricant, suspending agent, clay stabilizer, oil displacement agent, water loss reducer and thickener. During production, it is mostly made into granular polyacrylamide through an extruder to facilitate subsequent storage, transportation and use.

[0003] In the prior art, extruders used to produce polyacrylamide mostly include a machine body and a screw rotatably arranged in the machine body, a rotating chamber is arranged in the machine body, the screw is rotatably arranged in the rotating chamber, a driving motor is arranged in the machine body, a rotating shaft of the driving motor is connected and drives the screw to rotate, a plurality of extrusion holes communicating with the rotating chamber are arranged at one end of the machine body, and a feed hopper communicating with the rotating chamber is arranged at the top of the machine body. When in use, the driving motor is started to drive the screw to rotate, and the colloidal polyacrylamide is poured into the rotating chamber through the feed hopper, and the screw drives the colloid to rotate forward until the colloid is against one end of the rotating chamber. Under the continuous extrusion of the subsequent colloid, the colloid is extruded through the extrusion hole, and is made into granular polyacrylamide in cooperation with the subsequent cutter or other equipment.

[0004] However, in actual use, polyacrylamide has a certain viscosity. During the process of continuous squeezing and pushing of the screw in the rotating chamber, part of the colloidal polyacrylamide will stick to the screw, and the screw needs to be frequently disassembled for cleaning, otherwise it will cause blockage. However, the connection between the extruder screw and the drive motor shaft in the prior art is mostly connected by multiple bolts or flanges, etc., which makes it inconvenient to disassemble the screw. Utility Model Content

[0005] In order to improve the convenience of screw disassembly, the present application provides a polyacrylamide extruder.

[0006] The polyacrylamide extruder provided in this application adopts the following technical solution:

[0007] A polyacrylamide extruder comprises a machine body and a screw, wherein the machine body is provided with a rotating cavity, the screw is rotatably arranged in the rotating cavity, the machine body is provided with a driving motor, a rotating block is arranged on the rotating shaft of the driving motor, the screw is provided with a rotating groove, the rotating block is inserted into the rotating groove and abuts against the inner wall of the rotating groove, the machine body is provided with a mounting block, the mounting block is provided with a sliding groove, a sliding block is slidably arranged in the sliding groove, the driving motor is arranged on the sliding block, the mounting block is provided with a locking assembly, and the locking assembly is used to lock the sliding block.

[0008] By adopting the above technical scheme, the rotating block on the driving motor is inserted into the rotating groove on the screw rod during use, and at the same time, the mounting block locks the sliding block through the locking assembly so that the sliding block cannot move, thereby locking the driving motor so that the rotating block cannot exit the rotating groove. When the driving motor is started, the rotating block is driven to rotate, thereby pushing the inner wall of the rotating groove through the side wall of the rotating block to drive the screw rod to rotate. When the screw needs to be disassembled for cleaning, the locking of the sliding block is released by the locking assembly, and the sliding sliding block drives the driving motor to slide, thereby making the rotating block exit the rotating groove. At this time, the screw rod can be taken out of the rotating cavity to complete the disassembly. The screw and the driving motor shaft are connected through the rotating block, and there is no need to connect them through complicated methods such as multiple bolts, thereby improving the convenience of disassembly and replacement of the screw rod.

[0009] Preferably, the mounting block is provided with a locking groove communicated with the sliding groove, the sliding block can be inserted into the locking groove, the locking assembly includes a locking block and a locking spring, the locking block is slidably arranged in the locking groove and can resist the sliding block, the locking spring is arranged in the locking groove, and the locking spring connects the inner wall of the locking groove and the locking block.

[0010] When the locking spring is fully restored, the locking block stops and presses against the sliding block, completing the installation of the screw rod, thereby improving the convenience of screw removal and installation.

[0011] Preferably, the sliding block can slide in the locking groove.

[0012] By adopting the above technical solution, when disassembling the screw, the sliding stop block compresses the stop spring, and then the sliding block makes the rotating block disengage from the rotating groove. At this time, the sliding block is inserted into the sliding groove. After the sliding block and the stop block are released, the stop spring restores and pushes the stop block. The stop block pushes the sliding block to slide in the stop groove, so that the driving motor is no longer on the extension line of the rotating cavity, thereby facilitating the pulling out of the bolt from the rotating cavity. At the same time, it is also convenient to insert the screw back into the rotating cavity after cleaning, thereby improving the convenience of screw disassembly and installation.

[0013] Preferably, the sliding block is provided with a first guide surface, and the locking block is provided with a second guide surface that can abut against the first guide surface.

[0014] By adopting the above technical solution, when the sliding block is pushed out of the sliding groove and inserted into the locking groove, or when the sliding block is pushed back into the sliding groove, the first guide surface on the sliding block and the second guide surface on the locking block abut against each other, so that pushing the sliding block can drive the locking block to slide, thereby improving the convenience of the sliding block moving in the sliding groove and the locking groove.

[0015] Preferably, the mounting block is provided with a protective cover, the protective cover is against the machine body, the drive motor is arranged in the protective cover, and a mounting component is arranged between the mounting block and the protective cover, and the mounting component is used to install the protective cover on the mounting block.

[0016] By adopting the above technical solution, the protective cover is installed on the mounting block through the mounting assembly and is close to the body. The protective cover covers the drive motor and the drive block, reducing the possibility of collision damage to the drive motor and the drive block and improving the overall durability.

[0017] Preferably, the mounting assembly includes a first mounting magnetic sheet and a second mounting magnetic sheet, the mounting block is provided with a mounting groove, the protective cover can be inserted into the mounting groove, the first mounting magnetic sheet is arranged in the mounting groove, the second mounting magnetic sheet is arranged on the protective cover, and the first mounting magnetic sheet and the second mounting magnetic sheet are magnetically attracted to each other.

[0018] By adopting the above technical solution, when installing the protective cover, the side wall of the protective cover is inserted into the installation groove, so that the second installation magnetic sheet on the protective cover fits with the first installation magnetic sheet in the installation groove, and the first installation magnetic sheet and the second installation magnetic sheet are magnetically attracted to each other, and the installation is completed. When disassembling, the protective cover can be pulled out, thereby improving the convenience of installation and disassembly of the protective cover.

[0019] Preferably, the machine body is provided with an assembly groove communicated with the rotating chamber, an extrusion plate is inserted in the assembly groove, the extrusion plate is provided with a plurality of extrusion holes, the machine body is provided with a discharge groove communicated with the assembly groove, the extrusion holes can be communicated with the discharge groove, the extrusion plate is provided with a positioning groove communicated with the rotating groove, and the screw can be inserted into the positioning groove.

[0020] By adopting the above technical solution, during long-term use, because polyacrylamide has a certain viscosity, the colloidal polyacrylamide continuously squeezes the extrusion plate during use, and a lot of residues may be left on the extrusion plate, which needs to be cleaned in time. When the screw is disassembled, because the screw is out of the positioning groove, the extrusion plate can be pulled out from the top to make the extrusion plate out of the assembly groove for cleaning or replacement, which improves the convenience of disassembly of the extrusion plate. During installation, the extrusion plate is inserted into the assembly groove and the extrusion hole is connected to the discharge groove. At this time, the screw is installed. After the screw is installed in the rotating cavity, it is inserted into the positioning groove to complete the positioning. The operation is simple and convenient.

[0021] Preferably, the top wall of the extrusion plate is provided with an auxiliary groove.

[0022] By adopting the above technical solution, the auxiliary groove makes it easy to pull the extrusion plate out of the assembly groove, thereby improving the convenience of disassembling the extrusion plate.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting a machine body, a rotating cavity, a screw, a driving motor, a mounting block, a sliding groove, a rotating block, a rotating groove and a locking assembly, the locking assembly on the mounting block locks the sliding block in the sliding groove, so that the rotating block on the driving motor is inserted into the rotating groove of the screw. When the screw needs to be disassembled for cleaning, the locking of the sliding block is released by the locking assembly, and the sliding sliding block drives the driving motor to move, so that the rotating block is separated from the rotating groove on the screw, and the connection between the screw and the driving motor is released. After that, the screw can be taken out from the rotating cavity on the machine body, which greatly improves the convenience of screw disassembly;

[0025] 2. By providing a locking groove, a locking block and a locking spring, the locking spring pushes the locking block to resist the sliding block, so that the sliding block cannot slide into the locking groove, thereby allowing the rotating block to be inserted into the rotating groove. When the screw needs to be removed, the locking block is pushed to compress the locking spring, and the sliding block is pushed to insert the sliding block into the locking groove. At this time, the rotating block is separated from the rotating groove, and the connection between the screw and the drive motor is released, thereby removing the screw;

[0026] 3. By setting the extrusion plate, assembly groove, extrusion hole, discharge groove and positioning groove, after the screw is disassembled so that the screw is out of the positioning groove, the extrusion plate can be pulled out of the assembly groove for cleaning.
