Description

Technical Field

[0001] This utility model relates to the field of grinding devices, and more particularly to a grinding device for the inner wall of a reaction vessel. Background Technology

[0002] A reaction vessel is a closed container used for physical or chemical reactions, capable of heating, cooling, stirring, and other operations. It is widely used in chemical, pharmaceutical, food, and petroleum industries. A reaction vessel mainly consists of a main structure and key components; the main structure includes the vessel body and the vessel lid.

[0003] After a period of use, residues (such as resins and adhesives) easily adhere to the inner wall of a reactor, leading to decreased heat transfer efficiency and unstable product quality. Therefore, grinding the inner wall is necessary to remove these residues. Some media are corrosive, and during reaction within the reactor, they may cause erosion of the passivation layer on the inner wall, resulting in decreased smoothness and corrosion resistance. Grinding the inner wall is also necessary to improve smoothness and restore corrosion resistance. In some industries with high hygiene and cleanliness requirements, regular grinding is necessary to prevent microorganisms from entering and ensure the reaction environment meets regulatory standards.

[0004] There are two main existing polishing methods. One is manual polishing, where a person manually enters the vessel to polish its inner wall. However, this method is prone to omissions and cannot guarantee a thorough polishing of the vessel's inner wall. Furthermore, it is inefficient, labor-intensive, and the working environment is harsh. The other method is high-pressure water jet polishing, which uses high-pressure water to remove loose dirt and reduce damage to the vessel's inner wall. However, this method cannot improve the smoothness of the vessel's inner wall and has a narrower application range. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a grinding device for the inner wall of a reaction vessel, which aims to improve the problem in the prior art that the diameter of the grinding block cannot be adjusted to adapt to grinding different inner walls of the vessel.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: it includes a frame, a support column is fixedly connected to the top rear end of the frame, an electric telescopic rod is fixedly connected to the top extension end of the support column, a motor is fixedly connected to the end of the electric telescopic rod, a threaded column is fixedly connected to the output end of the motor, a connecting plate is fixedly connected to the bottom of the threaded column, an extension rod is hinged to the bottom of the connecting plate, a sliding groove is provided on the side wall of the extension rod, a sanding plate is fixedly connected to the bottom end of the extension rod, and an adjustment component is provided on the outer wall of the threaded column.

[0007] Preferably, an extension frame is fixedly connected to both sides of the middle end of the support column, and a clamping block is slidably connected inside the extension frame. A bidirectional threaded rod is threadedly connected to the rear end of the two clamping blocks. A worm gear is fixedly connected to the middle end of the bidirectional threaded rod, and the worm gear meshes with a worm. A rocker arm is fixedly connected to the outer end of the worm.

[0008] Preferably, the middle end of the bidirectional threaded rod is rotatably connected to the back bracket of the support column, and the worm gear is rotatably connected to the middle bracket of the support column.

[0009] Preferably, the adjusting assembly includes a threaded collar, which is internally threaded onto a threaded post. A sliding frame is slidably connected to the outer wall of the threaded collar, and a pressing rod is connected to the bottom of the sliding frame, the pressing rod passing through the sliding groove.

[0010] Preferably, the extrusion rod is a straight rod, and an arc-shaped rod is connected between the extrusion rods. The slide frame is connected to a vertical rod, which passes through the connecting plate, and the end of the vertical rod is fixed to the arc-shaped rod.

[0011] Preferably, the support column is threaded with a bolt at its middle end, the bolt is slidably connected with an auxiliary block at its end, and a dust collection box is fixedly connected to the front end of the frame.

[0012] Preferably, the auxiliary block has an arc-shaped contact surface that contacts the outer wall of the vessel.

[0013] Preferably, the sand plate is an arc-shaped elliptical block that contacts the inner wall of the vessel.

[0014] This utility model has the following beneficial effects: 1. By manually rotating the threaded collar, the sliding frame moves up and down. Then, the sliding frame drives the extrusion rod to squeeze the slide groove. The slide groove is then pressed, causing the extension rod to make a fan-shaped movement along the bottom hinge of the connecting plate, thereby changing the working range diameter of the four sets of sand plates to adapt to the needs of grinding the inner wall of the vessel of different sizes.

[0015] 2. Before grinding the reactor, manually rotate the bolt to make the auxiliary block contact the reactor body, so that the electric telescopic rod is aligned with the center of the inner wall of the reactor. Then, manually rotate the rocker arm to make the worm gear rotate, and then the worm gear meshes with the worm wheel to rotate. Then, the worm wheel drives the bidirectional threaded rod to rotate, and then the bidirectional threaded rod drives the clamping block to move inward along the inner wall of the extension frame to clamp the outer wall of the reactor, so as to achieve stable fixation on the reactor body and avoid the rotational force during grinding causing the frame to move and deviate.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Reference Figures 1-3 This utility model provides an embodiment of a grinding device for the inner wall of a reaction vessel, comprising a frame 1 with rollers at the bottom for easy movement of the grinding device and improved grinding efficiency. A vertical support column 2 is fixedly connected to the rear top of the frame 1, supporting the grinding device and optionally including a ladder for easy manual observation of the grinding process. The support column 2 has a horizontal extension at its top, with a vertical electric telescopic rod 3 fixedly connected thereto, driving the grinding device to reciprocate up and down for comprehensive grinding of the inner wall of the vessel. A motor 4 is fixedly connected to the output end of the electric telescopic rod 3, providing the power for grinding. A threaded column 5 is fixedly connected to the output end of the motor 4, with a connecting plate 6 fixedly connected to the bottom of the threaded column 5, driving the connecting plate to rotate via the threaded column. An extension rod 7 is hinged to the bottom of the connecting plate 6. Four sets of extension rods 7 are provided. A sand plate 9 is fixedly connected to the bottom end of each extension rod 7. The sand plate 9 is elliptical in shape and can contact the inner wall of the vessel. The extension rod rotates around the hinged part to expand or retract the sand plate 9, changing the working diameter of the four sets of sand plates 9. A sliding groove 8 is provided in the middle of the extension rod 7, with openings on both sides. An adjustment component is provided on the threaded column 5. The adjustment component cooperates with the extension rod, driving the extension rod to expand or retract.

[0020] Reference Figures 3-5The adjusting assembly includes a threaded collar 10, which has an I-shaped retaining ring that engages with the inner hole of the sliding frame and allows the sliding frame 11 to move up and down. A ring-shaped handle is located at the top of the threaded collar for manual rotation. The inner wall of the threaded collar 10 has internal threads, and the threaded collar is threaded onto the threaded post 5. Four sets of uprights are located at the bottom of the sliding frame 11, passing through a connecting plate and sliding up and down relative to the connecting plate. The adjusting assembly includes four cylindrical extrusion rods 12, which pass through the grooves of the extension rod. The extrusion rods are connected by arc-shaped rods, which are fixed to the ends of the uprights. During the rotation of the threaded collar, the sliding frame 11 moves up and down relative to the threaded post. The sliding frame, through the uprights and arc-shaped rods, drives the extrusion rods to move up and down. The extrusion rods, through the grooves, drive the extension rods to expand or retract.

[0021] Reference Figures 3-5 The support column 2 has two horizontal extension frames 13 fixedly connected to its middle ends. Each extension frame 13 has two sets of horizontal moving slots, and each extension frame is connected to a clamping block 14. The contact surfaces of the two clamping blocks are arc-shaped to clamp the outer surface of the reactor body. The rear end of the clamping block 14 is provided with an internal threaded hole. The back of the middle end of the support column is provided with a horizontal bidirectional threaded rod 15 through a back bracket. The two ends of the bidirectional threaded rod 15 are respectively engaged with the internal threaded holes of the corresponding clamping blocks. By rotating the bidirectional threaded holes, the two clamping blocks can be moved closer or separated synchronously. A worm gear 19 is fixedly connected to the middle of the bidirectional threaded rod 15. The worm gear 19 meshes with a worm 20. A rocker arm 21 is fixedly connected to the end of the worm 20. The worm 20 can be manually rotated by the rocker arm 21. A middle bracket is fixed to the back of the middle of the support column. One end of the worm is rotatably connected to the support column, and the other end of the worm is rotatably connected to the end bracket.

[0022] Reference Figures 2-4 The support column 2 is connected to a bolt 16 that penetrates the support column. The end of the bolt 16 is rotatably connected to an auxiliary block 17. The front contact surface of the auxiliary block 17 is arc-shaped and is used to contact the vessel body to keep the support column 2 at a certain distance from the vessel body. Rotating the bolt 16 can adjust the distance between the auxiliary block 17 and the support column, so that the electric telescopic rod 3 is aligned with the center of the vessel body. The front end of the frame 1 is fixedly connected to a dust collection box 18, which is located below the vessel body outlet. The dust collection box 18 is used to collect impurities and dust during the grinding process. The auxiliary block 17 is an arc-shaped contact block that contacts the outer wall of the vessel body.

[0023] Working principle: When grinding the inner wall of the vessel of different sizes, the threaded collar 10 is manually rotated to drive the sliding frame 11 to move up and down. Then, the upright rod and the arc-shaped rod drive the extrusion rod 12 to rise and fall. The extrusion rod pushes the extension rod 7 to make a fan-shaped movement along the bottom hinge of the connecting plate 6 through the sliding groove 8, thereby changing the outer contour diameter of the four sets of sand plates 9 and fitting them to the inner wall of the vessel. Then, the motor 4 is turned on to drive the threaded column 5 to rotate. The threaded column 5 drives the connecting plate 6 to rotate, and then the connecting plate 6 drives the extension rod 7 to rotate. Then, the extension rod 7 drives the sand plates 9 to perform grinding operations on the inner wall of the vessel.
