Description

Technical Field

[0001] The utility model relates to the technical field of industrial silicon crushing, in particular to a hammer crusher which is easy to protect. Background Art

[0002] Industrial silicon is mainly divided into two categories according to its use: metallurgical silicon and chemical silicon. Metallurgical silicon is used in the production of aluminum-silicon alloys and other fields, while chemical silicon is used in the production of organic silicon, semiconductor materials and solar-grade silicon. Industrial silicon cannot be separated from the crushing process in production. Before smelting, in order to select ore with higher silicon content from silicon ore, the selected ore will be crushed to an appropriate particle size by a crusher and then carried out subsequent processes. Usually, the finishing particle size requirement for industrial silicon is 20-100mm.

[0003] Hammer crusher is a kind of equipment that crushes materials by impact, and it is divided into two types: single rotor and double rotor. It is a crusher that directly crushes materials with a maximum particle size of 600-1800 mm to 25 or less mm.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. Traditional silicon blocks are generally finished by manual hammering to a specified particle size. Silicon wafers fly everywhere during work, often causing injuries and frequent accidents. At the same time, a large number of people are required from pouring to finishing of industrial silicon, resulting in high labor intensity and low production efficiency. 2. The internal crushing components of the existing crusher are too close to the feed material, resulting in splashing of the raw materials during crushing, and the external shell is an integrated structure. The internal crushing components will be damaged due to the processing of stones, resulting in inconvenience in maintenance. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 6 The utility model provides a technical solution: a hammer crusher that is easy to protect, including a frame 1, a chassis 2 is welded in the middle of the frame 1, an inspection door 3 is rotatably connected to one side of the chassis 2, a feed box 4 is installed on the top of the chassis 2 by bolts, a crushing assembly 5 is installed on the bearing opened on the inner wall of the chassis 2, both ends of the crushing assembly 5 are installed and connected with a transmission assembly 6 through a rotating shaft, the transmission assembly 6 is closely connected to the outer wall of the chassis 2, a servo motor 7 is installed on the outer wall of the transmission assembly 6 by bolts, and a material distribution tray 8 is opened inside the chassis 2.

[0026] A slide plate 401 is welded to the bottom of the feed box 4, and a flap 402 is provided on the surface of the slide plate 401. Gears 403 are respectively installed at both ends of the flap 402 through a rotating shaft. The gears 403 are rotatably connected to the inner wall of the feed box 4 through the rotating shaft. The gears 403 are respectively meshed and connected with chains 404. One end of the chain 404 is respectively installed with a moving block 405 through a pull rope. A limit block 406 is provided between the moving block 405 and the chain 404. The limit block 406 is welded to the inner wall at both ends of the feed box 4.

[0027] The crushing assembly 5 includes a chassis 501 and a pressure plate 502 , which are connected by bidirectional bolts. The chassis 501 is sleeved with a hammer head 503 through a shaft rod provided on the surface of the chassis 501 .

[0028] The two ends of the inner wall of the transmission component 6 are rotatably connected with a driving pulley 601 and a driven pulley 602 through a rotating shaft. The driving pulleys 601 are connected through a rotating shaft, and the two ends of the driven pulley 602 are connected to the crushing component 5 through a rotating shaft. The driving pulley 601 and the driven pulley 602 are connected through a belt 603 sleeved on their outer walls.

[0029] In this embodiment, Figure 2 and Figure 5As shown, the top of the chassis 2 is connected with the bottom of the feed box 4, and the bottom of the chassis 2 is provided with a discharge port which is wider at the top and narrower at the bottom, and the surfaces of the chassis 2 and the inspection door 3 are respectively provided with protrusions for snap-fitting connection, and the protrusions between the chassis 2 and the inspection door 3 are connected by bolts; compared with the general crusher, the feed port is directly exposed to the outside, resulting in the splashing of gravel due to high-speed rotation of the raw materials during processing, which not only causes the leakage of raw materials to cause waste but also easily causes safety hazards caused by accidental injuries to surrounding operators. The protection during raw material processing is improved by adding the feed box 4, and when the internal hammer head 503 is worn and needs to be replaced, it can be maintained by opening the inspection door 3, which improves the effect of facilitating daily maintenance during equipment operation.

[0030] In this embodiment, Figure 3 As shown, the slide plate 401 is inclined, and the flap 402 is located at the lowest point of the slide plate 401 surface, and the slide plate 401 is at the same horizontal position as the through hole on the top of the chassis 2, and the width of the slide plate 401 is consistent with the specification of the through hole on the top of the chassis 2; the structure of the feed box 4 is convenient for the delivery of raw materials, and at the same time, the inclined slide plate 401 at the bottom is used to make the raw materials flow into its lowest surface under the action of gravity, and the problem of raw materials falling too fast is reduced by adding the slide plate 401, so as to reserve time for the raw material crushing process below, so as to avoid the raw materials falling too fast and accumulating on the surface of the crushing component 5 to cause blockage, thereby causing the hammer head 503 to wear and increase the maintenance cost.

[0031] In this embodiment, Figure 4As shown, the gear 403 forms a rotating structure through the flap 402, and the chain 404 forms a transmission structure on the inner wall of the feed box 4 through the gear 403, and the moving block 405 forms a sliding mechanism on the inner wall of the feed box 4 through the chain 404 and the pull rope, and at the same time, a spring is wound around the outside of the pull rope between the moving block 405 and the limit block 406, and the moving block 405 forms an elastic reset structure through the spring; the ore has a certain weight, and when it is accumulated to a certain amount, it squeezes and pushes the flap 402 to flip and fall into the chassis 2. When the flap 402 rotates, it drives the gear 403 to rotate accordingly under the action of the rotating shaft. Since the head end of the chain 404 connected to the gear 403 is welded as a whole, the rotation of the gear 403 in the meshing structure will drive the rest of the chain 404 to be transmitted together with it, so that the chain 404 slides on both ends of the inner wall of the feed box 4. The movable block 405 is in a moving state, and as the chain 404 slides, the movable block 405 connected thereto by the pull rope slides accordingly. Because of the spring provided between the movable block 405 and the limit block 406, and the limit block 406 fixed inside the feed box 4, the sliding trajectory of the movable block 405 is limited, resulting in the movable block 405 squeezing the spring during the forward sliding process. After the spring is stressed, it applies the same reaction force again under the elastic trend to reset the movable block 405. While the movable block 405 is reset, it drives the pull rope to pull the chain 404 in the reverse direction again for transmission. As the chain 404 is driven in the reverse direction, the gear 403 inside it is driven in the reverse direction, so as to achieve the purpose of resetting the external flap 402. Through the transmission of the internal gear 403 and the chain 404, the flap 402 is reciprocated under the action of the limit block 406 and the spring, so that the raw materials fall onto the surface of the crushing component 5 in an orderly manner.

[0032] In this embodiment, Figure 5 and Figure 6 As shown, the crushing components 5 are connected through a rotating shaft, and the output end of the servo motor 7 is installed and connected to the driving pulley 601 on one side, and the crushing component 5 is rotatably connected to the inside of the chassis 2 through the driving pulley 601 and the driven pulley 602, and the hammer head 503 is distributed in an annular shape and rotatably connected between the chassis 501 and the pressure plate 502; the servo motor 7 drives, and the driving pulleys 601 on both sides are driven at the same time under the coaxial drive, and under the connection of the belt 603, the driven pulley 602 is rotated to achieve the purpose of driving the internal crushing component 5 to rotate. Due to the high hardness of the ore, the hammer head 503 is made of high-chromium cast iron, which is annularly sleeved between the chassis 501 and the pressure plate 502. When the crushing component 5 rotates, the hammer head 503 rotates 240 degrees inside the chassis 2 to hammer the falling stones, and the transmission structure at both ends is used to drive the rotation of the crushing component 5 to strengthen the stability of the crushing process.

[0033] In this embodiment, Figure 5As shown, a metal panel for filtering is provided at the bottom of the distribution tray 8, and the distribution tray 8 is slidably connected to the slide groove of the inner wall of the chassis 2 through a slider provided on its outer frame, and the distribution tray 8 is located between the crushing component 5 and the discharge port at the bottom of the chassis 2; general crushers lack a filtering function, resulting in the aggregation of crushed stones that reach the crushing particle size and crushed stones that do not meet the crushing specifications, increasing the time efficiency of subsequent sorting, and when the raw materials are processed by the crushing component 5, they fall inside the chassis 2 due to gravity, and the stones that do not meet the crushing force will not be able to pass through the distribution tray 8 due to their large specifications and will be trapped on its surface, while the crushed stones that meet the specifications will fall into the discharge port at the bottom of the chassis 2 through the through holes on its surface, and be discharged, and the raw materials collected inside the distribution tray 8 can be pulled out through its sliding structure and crushed for a second time.

[0034] The use method and advantages of the utility model: When the hammer crusher which is easy to protect is used, the working process is as follows:

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, first, a container rack for collecting crushed stone raw materials is placed on the vertical pole in the middle of the frame 1, that is, at the bottom feed port of the chassis 2, and raw materials are put in through the feed port on one side of the feed box 4. The crushed stone falls onto the slide plate 401 and rolls to the side of the flap 402 with gravity. When the stone is continuously rolling, the flap 402 is squeezed and flips over on the surface of the slide plate 401 to open a gap. The stone falls onto the surface of the crushing component 5 from the gap. When the flap 402 rotates, it drives the gear 403 to rotate accordingly under the action of the rotating shaft. The rotation of the gear 403 drives the chain 404 to transmit together. As the chain 404 slides, the The pull rope and the moving block 405 connected thereto slide accordingly. The moving block 405 squeezes the spring on one side of the limit block 406 during the forward sliding process. After the spring is stressed, it applies the same reaction force again under the elastic trend to reset the moving block 405. While the moving block 405 is reset, it drives the pull rope to pull the chain 404 in the opposite direction again. As the chain 404 is driven in the reverse direction, the gear 403 inside it is driven in the reverse direction, thereby achieving the purpose of resetting the external flap 402. The feed box 4 is used to improve the safety of materials when they fall and are polished, avoid the problem of stone splashing, improve the protectiveness of the equipment, and The gear 403 and chain 404 inside the feed box 4 are driven by the limit block 406 and the spring to realize the purpose of reciprocating opening and closing of the flap 402, so that the raw materials fall into the surface of the crushing component 5 in an orderly manner, avoiding the problem of internal blockage caused by the stone falling too fast, further improving the service life of the equipment, and strengthening the protection performance of the equipment as a whole. With the drive of the servo motor 7, the active pulleys 601 on both sides are driven at the same time under the coaxial drive, and under the connection of the belt 603, the driven pulley 602 is rotated to achieve the purpose of driving the internal crushing component 5 to rotate, so that the hammer head 503 is correspondingly moved in the machine The box 2 rotates 240 degrees inside to hammer the falling stones. The stones are crushed by the hammer head 503 and then fall down due to gravity. The stones that do not meet the crushing force will not be able to pass through the dividing plate 8 due to their large specifications and will be trapped on its surface. The crushed stones that meet the specifications will fall into the through holes on its surface and be discharged from the discharge port at the bottom of the box 2 into the container. After all the stones are processed, the dividing plate 8 is slid and pulled to make the raw materials inside fall through the feed box 4 again for secondary crushing. If the hammer head 503 is worn during daily use, the bolts can be removed to open a gap in the inspection door 3 on one side of the box 2.
