A high-efficiency continuous pulping and mixing device

Abstract

This utility model relates to a high-efficiency continuous pulping and mixing device, including a mixing chamber with semi-circular inner walls at both ends. The mixing chamber contains an upper partition and a lower partition. The upper partition has a semi-circular arc structure and forms a pulping chamber with a circular or nearly circular cross-section between it and one end of the mixing chamber. The lower partition is longitudinally positioned at the lower end of the mixing chamber, forming a pulp storage chamber between it and the other end of the mixing chamber. A movable plate is hinged to the upper end of the lower partition. An electric cylinder is located at the top of the mixing chamber. The electric cylinder drives a connecting rod, which, in conjunction with a fixed rod, causes the sleeve and connecting rod to swing left and right, causing the movable plate to rotate. This changes the overflow rate of the pulp according to the amount of pulp stored in the storage chamber, avoiding the problems of excessive pulp causing backflow or insufficient pulp causing insufficient supply.

Description

Technical Field

[0001] This utility model relates to the technical field of pulping and mixing equipment, and in particular to a high-efficiency continuous pulping and mixing device for use in underground coal mines. Background Technology

[0002] Traditional pulping equipment includes a pulper, a storage tank, and a pumping device between the pulper and the storage tank. The pulper performs high-speed pulping and mixing, and the finished pulp is then pumped to the storage tank for storage and later use by the grouting pump. However, due to limited space in coal mines and the large number of pulping devices, underground space becomes increasingly congested. Existing technology employs an integrated continuous pulping and mixing device that combines a high-speed mixer with a storage tank, separated by upper and lower baffles. This allows the pulp in the mixing chamber to flow directly into the storage chamber via overflow, eliminating the cost of pumping equipment and saving space. However, in practical use, the planar structure of the baffles can affect the mixing of the pulping equipment, preventing the formation of stable vortices within the mixing chamber and thus affecting pulping quality. Secondly, the fixed height of the lower baffle makes it impossible to control the overflow of the pulp, leading to backflow or insufficient supply when there is too much or too little pulp in the storage chamber. Therefore, improvements are necessary to address these problems. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses a high-efficiency continuous pulping and mixing device. The upper baffle adopts a semi-circular arc structure to meet the high-speed mixing requirements of the pulping equipment, while the lower baffle adopts a height-adjustable structure, thereby changing the pulp overflow rate.

[0004] The specific technical solution is as follows: A high-efficiency continuous pulping and mixing device includes a mixing chamber. The inner walls of the left and right ends of the mixing chamber are semi-circular arc structures. An upper partition and a lower partition are arranged horizontally in the middle of the mixing chamber. The upper partition is located at the upper end of the mixing chamber and extends downwards, forming a pulping chamber with a circular or approximately circular cross-section between the upper partition and one end of the mixing chamber. The lower partition is longitudinally located at the lower end of the mixing chamber, forming a pulp storage chamber between the lower partition and the other end of the mixing chamber. Both the pulping chamber and the pulp storage chamber are equipped with mixing devices. A movable plate is hinged to the upper end of the lower partition, and two hinged ends of the top of the movable plate are respectively equipped with… A connecting rod is provided, with a sleeve fitted at the upper end of each connecting rod. The sleeve and the connecting rod are slidably connected. The upper end of the sleeve passes through the top of the mixing chamber and has a movable opening at the top of the mixing chamber. Hinges are provided on both sides of the top of the mixing chamber. The two hinges are respectively hinged to the middle of the two sleeves. The two sleeves are connected and fixed by a horizontally set fixed rod. An electric cylinder is provided at the top of the mixing chamber. A connecting rod is hinged to one end of the electric cylinder. The other end of the connecting rod is fitted onto the fixed rod, so that the electric cylinder drives the connecting rod to move the sleeve and the connecting rod left and right in conjunction with the fixed rod, thereby causing the movable plate to flip.

[0005] Furthermore, the upper partition plate is provided with mounting blocks at both ends, and the upper partition plate is fixedly connected to the inner wall of the mixing chamber through the mounting blocks.

[0006] Furthermore, the two ends of the movable plate are fitted to the inner wall of the mixing chamber through rubber seals.

[0007] Furthermore, the lower partition plate has a hinge groove at its top, and the lower end of the movable plate has a hinge part that cooperates with the hinge groove. A rubber seal is fitted on the outer wall of one end of the hinge part, so that the hinge part fits against the bottom end of the hinge groove through the rubber seal.

[0008] Furthermore, the rubber seal includes a rubber sleeve and a plurality of rubber baffles arranged on the outer wall of the rubber sleeve.

[0009] Furthermore, a fixing rod is horizontally connected between the upper and lower ends of the two sleeves.

[0010] Furthermore, the pulping chamber is provided with a feed inlet at the top.

[0011] Furthermore, the pulping chamber and the pulp storage chamber are respectively provided with pulp discharge pipes at opposite ends.

[0012] Furthermore, an upper liquid level sensor and a lower liquid level sensor are respectively installed on the inner walls at the upper and lower ends of the slurry storage chamber.

[0013] The beneficial effects of this utility model are reflected in: In this invention, the upper partition adopts a semi-circular arc structure and cooperates with the side wall of one end of the mixing chamber, so that the pulping chamber has a circular or nearly circular structure, which allows the pulp in the pulping chamber to form a vortex under the action of the high-speed stirring device, thereby ensuring pulping efficiency.

[0014] In this invention, a flip-up movable plate is provided at the top of the lower partition to change the height of the lower partition, thereby changing the overflow rate of the slurry according to the amount of slurry stored in the slurry storage tank, avoiding the problem of backflow caused by too much slurry or insufficient supply caused by too little slurry.

[0015] Rubber seals are installed at both ends of the movable plate and at the bottom of the movable plate to ensure sealing and reduce leakage of slurry into the gaps of the movable plate. Attached Figure Description

[0023] Please see the appendix Figure 1-4 This embodiment provides a high-efficiency continuous pulping and mixing device, including a mixing chamber 1. The inner walls of the left and right ends of the mixing chamber 1 are semi-circular arc structures. An upper partition 2 and a lower partition 3 are provided in the middle of the mixing chamber, which are distributed left and right. The upper partition 2 is set at the upper end of the mixing chamber 1 and extends downward. Mounting blocks 211 are provided at the ends of both sides of the upper partition 2. The upper partition 2 is fixedly connected to the inner wall of the mixing chamber 1 through the mounting blocks 211. The upper partition 2 has a semi-circular arc structure and forms a pulping chamber 8 with an approximately circular cross-section between it and one end of the mixing chamber, so that the pulp in the pulping chamber 8 can form a vortex under the action of high-speed pulping and mixing.

[0024] The lower partition 3 is longitudinally arranged at the lower end of the mixing chamber. The side of the lower partition 3 is fixedly connected to the inner wall of the mixing chamber 1 through a folding plate. The lower partition 3 and the other end of the mixing chamber 1 form a slurry storage chamber 9. A movable plate 4 is hinged to the upper end of the lower partition 3. A connecting rod 5 is hinged to each of the two ends of the top of the movable plate 4. A sleeve 6 is fitted on the upper end of each connecting rod 5. The sleeve 6 is slidably connected to the connecting rod 5. The upper end of the sleeve 6 passes through the top of the mixing chamber 1 and has a movable opening 101 at the top of the mixing chamber 1. Hinges 102 are provided on both sides of the top of the mixing chamber 1. The two hinges 102 are hinged to the middle of the two sleeves 6 respectively. The upper and lower ends of the two sleeves 6 are connected and fixed by a horizontally set fixed rod 61. An electric cylinder 7 is provided at the top of the mixing chamber 1. A connecting rod 71 is hinged to one end of the electric cylinder 7. The other end of the connecting rod 71 is fitted onto the fixed rod 61 located at the upper end. This allows the electric cylinder 7 to drive the connecting rod 71 to cooperate with the fixed rod 61 to drive the sleeve 6 and the connecting rod 5 to swing left and right, thereby causing the movable plate 4 to flip.

[0025] The pulping chamber 8 and the pulp storage chamber 9 are respectively equipped with a stirring device 10. The stirring device 10 in the pulping chamber 8 is a high-speed stirrer for rapid pulping; the stirring device 10 in the pulp storage chamber 9 is a low-speed stirrer to prevent the pulp from solidifying.

[0026] In this embodiment, the movable plate 4 is fitted to the inner wall of the mixing chamber 1 at both ends by rubber seals, and the lower partition 3 has a hinge groove 31 at its top. The lower end of the movable plate 4 has a hinge part 41 that mates with the hinge groove 31. A rubber seal is fitted on the outer wall of one end of the hinge part 41, so that the hinge part 41 fits against the bottom end of the hinge groove 31 through the rubber seal, thereby ensuring sealing and reducing leakage of slurry into the gaps of the movable plate 4. In this embodiment, the rubber seal includes a rubber sleeve 42 and a plurality of rubber baffles 43 arranged on the outer wall of the rubber sleeve 42. The rubber baffles 43 fit against the inner wall of the mixing chamber or the inner wall of the bottom end of the hinge groove 31 to achieve sealing.

[0027] The pulping chamber 8 is provided with a feed inlet 103 at the top. The pulping chamber 8 and the pulp storage chamber 9 are respectively provided with discharge outlets 104 at opposite ends. The discharge outlet 104 of the pulp storage chamber 9 is connected to the grouting system through a pipeline. The discharge outlet 104 of the pulping chamber 8 is used to discharge the remaining pulp after the equipment stops pulping.

[0028] The upper and lower liquid level sensors are respectively installed on the inner walls of the upper and lower ends of the slurry storage chamber 9. When the slurry level in the slurry storage chamber 9 is too high or too low, an alarm is triggered. Then, the overflow rate of the slurry is changed by changing the flip angle of the movable plate 4, thus avoiding the problem of backflow caused by too much slurry or insufficient supply caused by too little slurry.
