Description

Technical Field

[0001] This utility model relates to the field of acetylene production technology, and in particular to a crushing system that reduces generator blockage. Background Technology

[0002] The existing acetylene generator is a calcium carbide-injection water-type low-pressure acetylene generator, which consists of a storage hopper, a feeding pipe, a main generator shell, and an auxiliary generator cylinder, and is equipped with a safety water seal and a spray cooling tower. Its working principle is that calcium carbide is added to the generator storage hopper by the calcium carbide feeding bucket, and then the calcium carbide is added to the main generator cylinder by a vibrating feeder, where it reacts with water to generate acetylene gas.

[0003] Currently, the calcium carbide added to the generator's storage hopper is of varying sizes and has not been crushed, which easily leads to material blockage, affecting production efficiency and failing to meet usage requirements. Some manufacturers use jaw crushers for crushing, but jaw crushers have an open structure, resulting in severe dust generation during crushing, which has a significant impact on the on-site environment. Furthermore, it is difficult to achieve the required particle size. Since fine calcium carbide powder readily reacts with moisture in the air to form an explosive mixture, there is a risk of explosion during crushing, causing inconvenience to production. Utility Model Content

[0004] This invention provides a crushing system that reduces material blockage in the generator, solving the problems of traditional acetylene generators, such as inconsistent calcium carbide size before feeding, severe crushing pollution, easy material blockage, reduced production efficiency, and inability to meet usage requirements.

[0005] This utility model provides a crushing system for reducing generator blockage, including a screening and crushing box, a primary crusher, a secondary crusher, a storage silo, and a support. The screening and crushing box is mounted on the support. An inlet is located on the side wall of the screening and crushing box, and an outlet is located at the bottom. An inclined screen plate is installed inside the screening and crushing box. The high end of the screen plate receives and screens the material added from the inlet. The primary crusher is located at the low end of the screen plate. Below the primary crusher is a secondary crusher for crushing the material on the screen plate. A storage silo is located at the bottom of the screening and crushing box, and a discharge pipe is located at the bottom of the storage silo. A discharge device is installed on the discharge pipe. A dust suction port is located at the top of the screening and crushing box, and the dust suction port is connected to a pulse dust collector via a dust suction pipe.

[0006] Furthermore, the primary crusher includes a fixed crushing plate and a movable crushing plate. The fixed crushing plate is vertically arranged below the screen plate, and the movable crushing plate is inclinedly arranged on one side of the fixed crushing plate. The lower end of the movable crushing plate is rotatably connected to the side wall of the screening and crushing box. A hydraulic cylinder for driving the movable crushing plate to swing is provided on one side of the upper end of the movable crushing plate. The fixed end of the hydraulic cylinder is hinged to a first hinge seat provided on the side wall of the screening and crushing box, and the other end is hinged to a second hinge seat provided on the movable crushing plate.

[0007] Furthermore, the secondary crusher includes a crushing tube, a drive mechanism, a transmission mechanism, a crushing drive shaft, and crushing blades. The crushing tube is vertically arranged on the inner wall of the screening crushing box. Two crushing drive shafts are arranged inside the crushing tube, and multiple crushing blades are arranged on each crushing drive shaft. A drive mechanism for driving one of the crushing drive shafts to rotate is arranged outside the crushing tube. The two crushing drive shafts are connected by a transmission mechanism.

[0008] Furthermore, multiple crushing teeth are provided on the opposite sides of both the fixed crushing plate and the movable crushing plate.

[0009] Furthermore, both the unloader and the pulse dust collector are controlled by the control system.

[0010] Furthermore, multiple pneumatic vibrators are provided at the bottom of the sieve plate.

[0011] As can be seen from the above technical solutions, this utility model provides a crushing system that reduces material blockage in the generator.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Material is fed into the screening and crushing box through the feed inlet. The material is screened by the screen plate set in the screening and crushing box. Smaller materials pass through the screen plate and go directly into the storage bin. Larger lumps become oversize and are conveyed to the primary crusher through the screen plate. After being crushed by the primary crusher, they continue to enter the secondary crusher for further crushing. After crushing, they enter the storage bin for preparation. The material crushed by screening has a uniform particle size and will not cause material blockage during the feeding process, thus increasing production efficiency.

[0014] 2. By sending the dust in the screening and crushing box into the pulse dust collector through the dust suction pipe for treatment, the dust generated by the crushing system can be prevented from causing environmental pollution. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] Example 1:

[0029] See Figure 1-4A crushing system for reducing generator blockage includes a screening and crushing box 1, a primary crusher 2, a secondary crusher 3, a storage silo 4, and a support 5. The screening and crushing box 1 is mounted on the support 5. The screening and crushing box 1 has an inlet 11 on its side wall and an outlet 12 at its bottom. An inclined screen plate 13 is installed inside the screening and crushing box 1. The high end of the screen plate 13 is used to receive and screen the material added by the inlet 11. The primary crusher 2 is installed at the low end of the screen plate 13. The secondary crusher 3 is installed below the primary crusher 2 to crush the material on the screen plate 13. The storage silo 4 is installed at the bottom of the screening and crushing box 1. A discharge pipe 41 is installed at the bottom of the storage silo 4. A pneumatic vibrator can be installed on the outer wall of the storage silo 4. The discharge of material from the storage silo 4 is increased by a pneumatic vibrator to prevent material blockage. A discharge device 42 is installed on the discharge pipe 41 to facilitate the control of material discharge from the storage silo 4. A dust suction port 14 is installed on the top of the screening and crushing box 1. The dust suction port 14 is connected to a pulse dust collector through a dust suction pipe 15. Material is added into the screening and crushing box 1 through the feed port 11. The material is screened by the screen plate 13 installed in the screening and crushing box 1. Smaller materials pass through the screen plate 13 and enter the storage silo 4 directly. Larger lumps become oversize and are screened by the screen plate 13 and conveyed to the primary crusher 2. After being crushed by the primary crusher 2, the material continues to enter the secondary crusher 3 for further crushing. After crushing, the material enters the storage silo 4 for preparation. The material crushed by screening has a uniform particle size and does not block during the feeding process, which increases production efficiency.

[0030] In this embodiment, see Figure 2 The primary crusher 2 includes a fixed crushing plate 21 and a movable crushing plate 22. The fixed crushing plate 21 is vertically arranged below the screen plate 13, and the movable crushing plate 22 is inclinedly arranged on one side of the fixed crushing plate 21. The lower end of the movable crushing plate 22 is rotatably connected to the side wall of the screening and crushing box 1. A hydraulic cylinder 23 for driving the movable crushing plate 22 to swing is provided on one side of the upper end of the movable crushing plate 22. A dust cover is sleeved on the telescopic shaft of the hydraulic cylinder 23 to prevent dust accumulation. The fixed end of the hydraulic cylinder 23 is hinged to the first hinge seat provided on the side wall of the screening and crushing box 1, and the other end is hinged to the second hinge seat provided on the movable crushing plate 22.

[0031] In this embodiment, see Figure 2 , 3The secondary crusher 3 includes a crushing tube 31, a drive mechanism 32, a transmission mechanism 33, a crushing transmission shaft 34, and crushing blades 35. Each crushing blade 35 includes a fixed bushing 351 and crushing plates 352 symmetrically arranged on both sides of the fixed bushing 351. The fixed bushing 351 is fitted onto the crushing transmission shaft 34 and fixedly connected to the fixed bushing 351. Crushing teeth 353 are provided on the outer wall of the fixed bushing 351 and on the upper and lower sides of the crushing plates 352. The crushing tube 31 is vertically fixed on the inner wall of the screening and crushing box 1. Two horizontal crushing transmission shafts 34 are installed inside the crushing tube 31. Each crushing transmission shaft 34 is rotatably connected at both ends to bearings in bearing seats installed on the side wall of the crushing tube 31. Multiple crushing blades 35 are installed on each crushing transmission shaft 34. The gap between the crushing blades 35 is 10mm, facilitating the crushing of materials into uniformly sized particles. The crushing tube 31... An external drive mechanism 32 is provided to drive one of the crushing drive shafts 34 to rotate. The two crushing drive shafts 34 are connected by a transmission mechanism 33. The drive mechanism 32 includes a motor, which is mounted on the outer wall of the screening and crushing box 1. The output shaft of the motor passes through the side wall of the screening and crushing box 1 and the side wall of the crushing tube 31 in sequence, and extends into the screening and crushing box 1 to be coaxially and fixedly connected to one of the crushing drive shafts 34. The transmission mechanism 33 includes a gearbox, a first gear, and a second gear. The gearbox is fixed on the rear side wall of the crushing tube 31. The rear ends of the two crushing drive shafts 34 extend to the rear side and are suspended in the gearbox. A gear is coaxially fixed on each crushing drive shaft 34 in the gearbox. The two gears on the two crushing drive shafts 34 can mesh with each other to drive the two crushing drive shafts 34 to rotate in opposite directions, and drive the crushing blades 35 on the two crushing drive shafts 34 to interact and crush the material.

[0032] In this embodiment, see Figure 2 Multiple crushing teeth 221 are provided on the opposite sides of the fixed crushing plate 21 and the movable crushing plate 22. The crushing teeth 221 fix and crush the blocky material between the fixed crushing plate 21 and the movable crushing plate 22, preventing the material from sliding up and down during the process of the fixed crushing plate 21 and the movable crushing plate 22 squeezing the material, thereby increasing the crushing efficiency.

[0033] In this embodiment, the unloader 42, hydraulic cylinder 23, pulse dust collector, and drive mechanism 32 are all controlled by the control system. The hydraulic cylinder 23 uses a reversing valve to control the flow direction of the oil entering the hydraulic cylinder, thereby controlling the extension and retraction of the hydraulic cylinder, realizing frequent driving of the movable crushing plate 22, so that the movable crushing plate 22 approaches the fixed crushing plate 21 to squeeze and crush the blocky material between the two. The unloader 42 controls the discharge of material through the buttons of the DCS control box.

[0034] In this embodiment, multiple pneumatic vibrators 6 are installed at the bottom of the screen plate 13. The pneumatic vibrators 6 are ball vibrators K10T. The pneumatic vibrators 6 apply vibration force to the bottom of the screen plate 13, causing the screen plate 13 to vibrate. The screen plate 13 quickly separates the fine particles that do not need to be crushed, and screens out the larger block materials and sends them into the primary crusher 2 for crushing.

[0035] As can be seen from the above technical solution, during use, firstly, the pulse dust collector is turned on by the controller, so that the gas inside the screening and crushing box 1 is discharged upward from the dust inlet 14 into the dust suction pipe 15 and introduced into the pulse dust collector. The dust is treated by the pulse dust collector. Then, the hydraulic cylinder 23 is operated by the controller, which drives the movable crushing plate 22 to swing relative to the fixed crushing plate 21. At the same time, the pneumatic vibrator 6 is started to vibrate the bottom of the screen plate 13. Then, calcium carbide is added into the screening and crushing box 1 through the feed inlet 11. The calcium carbide is screened by the screen plate 13 set in the screening and crushing box 1. Smaller calcium carbide passes through the screen plate 13 and directly enters the storage bin 4. Larger block materials become oversize material and pass through the screen plate 13. The calcium carbide particles are screened and conveyed to the primary crusher 2, falling between the fixed crushing plate 21 and the movable crushing plate 22. During the swinging process of the movable crushing plate 22, larger calcium carbide particles are crushed and pass through the gap between the lower ends of the fixed crushing plate 21 and the movable crushing plate 22, falling into the secondary crusher 3. The two crushing drive shafts 34 are driven by two gears that mesh with each other, causing the two crushing drive shafts 34 to rotate in opposite directions. This drives the crushing blades 35 on the two crushing drive shafts 34 to interact and further crush the calcium carbide. After crushing, the particles enter the storage bin 4 for preparation. Compared with the primary crusher 2, the secondary crusher 3 crushes calcium carbide particles with a more uniform particle size, which is convenient for loading and unloading in the storage bin 4 and will not cause blockage.
