[0034] Industrial silicon, also known as metallic silicon or crystalline silicon, is mainly used as an additive for non-ferrous alloys. The main raw materials for smelting industrial silicon are silica and carbonaceous reducing agents, and its production process is as follows: raw material silica is washed with water → drained and dried → crushed → screened → proportioned → melted → slagged → water-cooled and solidified. Among them, the original silica needs to be initially crushed into silicon blocks in a crushing mechanism. The silicon blocks fall out through the discharge port of the crushing mechanism and are transported by a transport mechanism to a screening site for screening. The silicon blocks that cannot pass through the screen need to be put back into the crushing mechanism for secondary crushing.

[0035] According to the applicant's observation, it is found that currently most of the crushing and screening processes need to be carried out separately in the crushing yard and the screening yard. After the silica material is crushed, the crushed material needs to go through three processes of loading, transportation, and unloading and be put into the screening machine in the screening yard. This process takes a relatively long time, and at the same time, the screening process is affected by the transportation process, and the working time of the screening machine is discontinuous, thus increasing the working time of the crushing-screening process and further affecting the overall preparation efficiency during the preparation of industrial silicon.

[0036] In view of this, it is necessary to propose a crushing device to solve the above technical problems.

[0037] Please refer to Figure 1 , in an embodiment of the present utility model, the crushing device 100 includes a frame 1, a crushing mechanism 2, a feeding member 3, and a screening assembly 4. Among them, the crushing mechanism 2 is arranged on the frame 4; the feeding member 3 includes an inlet 31 and an outlet 32. The inlet 31 is communicated with the discharge port of the crushing mechanism 2. The height of the feeding member 3 gradually decreases from the inlet 31 to the outlet 32 direction. The feeding member 3 further includes a bottom plate 35, and the bottom plate 35 is inclined and arranged on the frame 1; the screening assembly 4 includes a screen 41, a receiving box 42, and a supporting frame 43 for carrying the receiving box 42. The screen 41 is arranged on the bottom plate 35, and the receiving box 42 is arranged below the screen 41.

[0038] Specifically, the frame 1 in this embodiment serves as the support for the entire crushing device 100 and is used to support and install functional structures or mechanisms such as the feeding member 3 and the crushing mechanism 2. The crushing mechanism 2 is installed on the frame 1. The crushing mechanism 2 includes a crusher 22, a motor 23 for driving the crusher 22, and an output shaft 24. The crusher 22 includes a feed inlet and a discharge outlet. The crusher 22 is one of a pair-roll crusher and a hob crusher. In this embodiment, the crusher 22 can be a pair-roll crusher. The as-mined silica falls into the gap between the pair of rolls through the feed inlet and is crushed into small silicon blocks as the pair of rolls rotate relative to each other. Due to gravity, the small silicon blocks fall towards the discharge outlet. Below the discharge outlet, a feeding member 3 is installed. The inlet 31 of the feeding member 3 is arranged facing the discharge outlet of the crusher 22. The feeding member 3 and the crusher 22 are connected by bolts so that the inlet 31 of the feeding member 3 is in communication with the discharge outlet to receive the silicon blocks falling from the discharge outlet. The bottom plate 35 included in the feeding member 3 is inclined to facilitate guiding the silicon blocks to slide along the inner wall of the bottom plate 35 and fall out from the outlet 32. There is a certain vertical distance between the outlet 32 and the frame 1. Specifically, when setting, it is based on facilitating the operation of workers or facilitating the silicon blocks to fall onto the conveyor belt. Further, a screening assembly 4 is provided below the bottom plate 35. The screening assembly 4 is used to screen the silicon material crushed by the crusher 22. Please refer to Figure 2 and Figure 3 , the screen 41 in the screening assembly 4 is arranged on the bottom plate 35, and the receiving box 42 is arranged below the screen 41. With such an arrangement, when the crushed silicon material slides past the screen 41 in the feeding member 3, the material smaller than the screening diameter can fall into the receiving box 42 through the screen holes in the screen 41. Since the feeding member 3 is connected to the crusher 22, the vibration of the crusher 22 can be transmitted to the feeding member 3, thereby driving the silicon material to vibrate on the bottom plate 35, and further improving the screening effect. The screen 41 is specifically arranged at the higher end of the bottom plate 35 in terms of position height. This arrangement enables the material to be directly screened when it falls, and with the kinetic energy of the material when it falls, the vibration of the material on the screen 41 is more obvious, thereby further improving the screening effect. The screened material falls into the receiving box 42. When the receiving box 42 is full, it is cleaned by workers. The collected material directly enters the batching process without the need for a screening process anymore.

[0039] In the embodiment provided by the present utility model, the crushing device includes a frame body 1, a crushing mechanism 2, a feeding member 3 and a screening assembly 4. Among them, the crushing mechanism 2 is arranged on the frame body 1; the feeding member 3 includes an inlet 31 and an outlet 32. The inlet 31 is communicated with the discharge port of the crushing mechanism 2. The height of the feeding member 3 gradually decreases from the inlet 31 to the outlet 32 direction. The feeding member 3 further includes a bottom plate 35, and the bottom plate 35 is inclined and arranged on the frame body 1; the screening assembly 4 includes a screen 41, a material receiving box 42 and a bearing frame 43 for bearing the material receiving box 42. The screen 41 is arranged on the bottom plate 35, and the material receiving box 42 is arranged below the screen 41. Through this setting, the material crushed by the crushing mechanism 2 directly falls into the feeding member 3. When sliding in the feeding member 3, the qualified material passes through the screen holes and falls into the material receiving box 42 through the screening of the screen 41. At the same time, due to the vibration of the crushing mechanism, the screening effect can be significantly improved. With such a setting, the loading and unloading and transportation processes in the crushing and screening processes during the industrial silicon processing can be omitted, and the situation of discontinuous working time of the screening machine can also be avoided, thereby reducing the time-consuming of the crushing-screening process, and further improving the overall efficiency during the preparation of industrial silicon.

[0040] In addition, in an embodiment, in order to facilitate the original silica stone to enter the feeding port of the crusher 22, a loading box 21 is arranged above the feeding port. The loading box 21 is installed on the top of the frame body 1. The loading box 21 is integrally in an inverted trapezoid shape. The opening area at the top of the loading box 21 is larger than the opening area at the bottom, which is beneficial to the loading of the original silica stone. The opening at the bottom of the loading box 21 is communicated with the feeding port of the crusher 22. The original silica stone loaded into the loading box 21 can enter the crusher 22 through the opening. The connection mode between the loading box 21 and the frame body 1 includes one of bolt connection or welding.

[0041] Further, in an embodiment of the present utility model, the bottom plate 35 is provided with a screening opening 33. The screen 41 is installed at the screening opening 33, the bearing frame 43 is installed on the bottom plate 35, and the material receiving box 42 is arranged in the bearing frame 43. Please refer to Figure 3 , a screening opening 33 is opened on the bottom plate 35, the screen 41 is installed in the screening opening 33. The size of the screening opening 33 matches the size of the screen 41, and the upper surface of the screen 41 does not protrude from the inner wall surface of the bottom plate 35. This setting can avoid the screen 41 protruding in the bottom plate 35, and avoid the phenomenon of material jamming when the material slides on the bottom plate 35 due to the protrusion of the screen 41. At the same time, the bearing frame 43 is installed on the bottom plate 35, and the material receiving box 42 is arranged in the bearing frame 43. Through this setting, there is no need to additionally set a bracket to support the bearing frame 43, and at the same time, the bearing frame 43 is avoided to be arranged on the bracket, which simplifies the structure, can make more effective use of space, and is convenient for material storage and processing in a limited space.

[0042] Please refer to Figure 3, Further, in an embodiment of the present utility model, a placement space is formed between the carrier 43 and the bottom plate 35. The material receiving box 42 is disposed in the placement space. The carrier 43 is formed with an opening communicating with the placement space, and the material receiving box 42 can be slid horizontally into or out of the placement space through the opening. Specifically, the top of the carrier 43 is connected to the bottom plate 35 of the material conveying member 3, so that the carrier 43 is hoisted on the outer wall of the bottom plate 35. The carrier 43 and the bottom plate 35 enclose a placement space, and the size of the placement space can satisfy the placement of the material receiving box 42 therein. On one side of the carrier 43, an opening communicating with the placement space is provided. The opening can be parallel to the length direction of the material conveying member 3 or perpendicular to the length direction of the material conveying member 3. When setting, it is necessary to make the size of the opening capable of allowing the material receiving box 42 to enter and exit. For the convenience of workers' operation, in this embodiment, the direction of the opening is set on the side away from the outlet 32 of the material conveying member 3 to ensure the operation space. On this basis, the material receiving box 42 can be pushed into or pulled out of the placement space. When the material receiving box 42 is pushed into the placement space, the material falling through the screen 41 can directly enter the material receiving box 42; when the material receiving box 42 is full, the worker pulls out the material receiving box 42 and collects the material, which is transported to the batching process by the transportation device. After the cleaned material receiving box 42 is pushed into the placement space again, the crushing and screening processes can be continued; by setting the material receiving box 42 to be pushed or pulled horizontally, it can be avoided that when the material receiving box 42 is full and the material receiving box 42 is pulled out, the material spills due to inclination. For the convenience of use, a handle is provided on the outer side of the pushing and pulling direction of the material receiving box 42, and the worker can hold the handle tightly to pull out or push in the material receiving box 42. In an embodiment, a plurality of material receiving boxes 42 are provided. After one material receiving box 42 is full, another empty material receiving box 42 is replaced in time. The full material receiving box 42 is centrally transported to the batching production line. After the crushed silicon blocks in the material receiving box 42 are emptied, it is transported to the vicinity of the crushing device 100 again to wait for replacement. This setting can effectively reduce the downtime of the crushing device 100.

[0043] In addition, in an embodiment of the present utility model, the carrier 43 includes two side plates 431. The two side plates 431 are respectively disposed on both sides of the opening. Card slots are provided on the inner walls of the two side plates 431, and the material receiving box 42 is provided with buckles that cooperate with the card slots. Please refer to Figure 2 , after the material receiving box 42 is pushed into the placement space, since the buckles on the material receiving box 42 are snapped into the card slots in the carrier 43, the material receiving box 42 will not be displaced due to the vibration of the material conveying member 3, so that the material can accurately fall into the material receiving box 42, avoiding the situation of material waste; at the same time, since the weight of the material receiving box 42 containing the material is relatively heavy, this setting can prevent the material receiving box 42 from accidentally slipping out of the opening of the carrier 43, thereby improving the safety of the overall structure.

[0044] In an embodiment of the present utility model, a material conveying cavity 34 is formed inside the material conveying member 3. The material conveying member 3 further includes a top plate 36 and a flexible blocking member 37. The flexible blocking member 37 is installed between the material screening opening 33 and the outlet 32 of the material conveying member 3, and is installed at one end close to the material screening opening 33. The top end of the flexible blocking member 37 is fixedly connected to the inner wall of the top plate 36, and the bottom end of the flexible blocking member 37 is a free end. The flexible blocking member 37 closes the material conveying cavity 34 without external force and can be bent under the action of external force to open the material conveying cavity 34. For details, please refer to Figure 3 , the material conveying cavity 34 is surrounded by the top plate 36, the bottom plate 35 and two vertical plates of the material conveying member 3. The flexible blocking member 37 is arranged in the material conveying cavity 34 and is located between the material screening opening 33 and the outlet 32 of the material conveying member 33. In this embodiment, the flexible blocking member 37 is arranged close to the material screening opening 33. The top end of the flexible blocking member 37 is fixedly connected to the top plate 36 of the material conveying member 3, so that the top end of the flexible blocking member 37 is stationary relative to the material conveying member 3, while the bottom end of the flexible blocking member 37 is a free end, and the bottom end can move around the top end under the action of external force, making the whole flexible blocking member 37 in a bent state. That is to say, the flexible blocking member 37 includes two states, an initial state and a bent state. When the flexible blocking member 37 is not affected by external force, it is in the initial state. In the initial state, the whole flexible blocking member 37 is in the same plane, and at this time the material conveying cavity 34 is divided into two cavities by the flexible blocking member 37; when affected by external force, the flexible blocking member 37 enters the bent state, and its bottom end moves to one side, driving the whole flexible blocking member 37 to bend, and at this time the whole material conveying cavity 34 is communicated. When the crushing device 100 works, the crushed silicon block material enters the material conveying member 3 and passes through the screen 41. Before the material reaches the flexible blocking member 37, the flexible blocking member 37 is in the initial state. After the silicon block reaches the flexible blocking member 37, the silicon block exerts an external force on the flexible blocking member 37. As the weight of the material pile gradually increases, the flexible blocking member 37 gradually bends towards the outlet 32 side of the material conveying member 3 and enters the bent state. When the flexible blocking member 37 bends to a certain extent, the material pile starts to slide towards the opening. Through this setting, the sliding speed of the material pile can be controlled, so as to ensure that the silicon block pile is fully screened by the screen 41 and improve the screening effect. Among them, the flexible blocking member 37 is connected to the top plate 36 of the material conveying member 3 through a clamping member 38. The top end of the clamping member 38 is fixedly installed on the inner wall of the top plate 36. The bottom end of the clamping member 38 is arranged in a "concave" shape, and a concave groove is formed at the bottom end. The top end of the flexible blocking member 37 is connected to the concave groove, so that the top end of the flexible blocking member 37 is relatively stationary with the clamping member 38; the connection method between the clamping member 38 and the flexible blocking member 37 includes one of pin connection and screw connection.

[0045] In an embodiment of the present utility model, the crushing device 100 further includes a vibration member 5 installed on the material conveying member 3. When the vibration member 5 is installed on the outer side of the material conveying member 3, the vibration member 5 can be arranged on the top plate 36, the bottom plate 35 or the outer walls of the two side vertical plates of the material conveying member 3; when the vibration member 5 is installed inside the material conveying member 3, the vibration member 5 can be arranged on the inner wall of the vertical plate or the top plate 36 of the material conveying member 3, so that the vibration member 5 can drive the material conveying member 3 to vibrate. Please refer to Figure 3 , in this embodiment, vibration members 5 are arranged on both side walls inside the material conveying member 3, and the vibration member 5 includes one of a small attached vibrator or a vibration motor. Through this arrangement, the material conveying member 3 can vibrate regularly, which is convenient for the material pile to be fully screened when passing through the sieve, and is beneficial to improving the screening effect; on the other hand, this arrangement can avoid the situation that the silicon block material accumulates in the material conveying member 3 and is difficult to slide down, thereby reducing the number of shutdowns for maintenance.

[0046] In an embodiment of the present utility model, the crushing device 100 further includes a dust suction assembly 6, and the dust suction assembly 6 is installed on the frame body 1 or the material conveying member 3. The dust suction assembly 6 includes an air duct 61 and a dust storage bin 62. The dust storage bin 62 includes a power hole and a dust storage cavity for accommodating dust. The air inlet of the air duct 61 is arranged corresponding to the outlet 32 of the material conveying member 3, and the air duct 61 is communicated with the dust storage cavity; the dust storage cavity is communicated with an external dust removal system through the power hole, a filter member is provided outside the power hole, and the external dust removal system is used to provide suction to the dust storage bin 62. Specifically, please refer to Figure 4 and Figure 5, in this embodiment, in order to reduce the overall structural volume, the dust collection component 6 is arranged on the material conveying component 3. This arrangement enables the crushing device 100 to integrate the functions of crushing and dust collection, realizing the integration of the crushing and dust collection functions. The air inlet of the air duct 61 is arranged near the outlet 32 of the material conveying component 3, so that the dust stirred up when the material drops from the outlet 32 can be timely sucked into the air duct 61. At the same time, the other end of the air duct 61 is communicated with the dust storage bin 62. There is a dust storage cavity for storing dust in the dust storage bin 62, and the dust sucked by the air duct 61 can be stored in the dust storage cavity. A power hole is also arranged in the dust storage bin 62, and the power hole is used to connect with an external dust removal system, so that the dust storage cavity is communicated with the external dust removal system, providing suction for the dust storage bin 62, and enabling the air duct 61 connected to the dust storage cavity to suck the dust into the dust storage cavity. In addition, in order to prevent the dust in the dust storage cavity from entering the external dust removal system, a filter element is covered at the power hole for filtering dust. Through this arrangement, the dust storage bin 62 and the air duct 61 can continuously maintain negative pressure, and thus the dust collection component 6 can complete the functions of dust collection and dust storage. Among them, there is a large amount of silicon powder in the stored dust. In this embodiment, the dust is collected and stored for subsequent recycling. In addition, in order to avoid affecting the dust collection effect, at the connection parts of the air duct 61 with the dust storage bin 62 and the dust storage bin 62 with the external dust removal system, sealed connecting parts 64 can be arranged, such as flange sealing parts and other components, to ensure the airtightness of the connection parts.

[0047] In another embodiment of the present utility model, more than two internal fans are connected in series at intervals between the air duct 61 and the dust storage bin 62, and the internal fans are connected by the air duct 61. Taking the example of connecting two internal fans in series, through this arrangement, after the fan closest to the air inlet of the air duct 61 sucks the dust from the outside into the air duct 61, the other fan can timely suck the dust in the air duct 61 into the dust storage bin 62. This arrangement can effectively improve the dust collection efficiency.

[0048] Furthermore, in an embodiment of the present utility model, the dust collection component 6 further includes a mounting plate 63. The mounting plate 63 is mounted on one end of the material conveying component 3 close to the outlet 32, and the dust storage bin 62 is detachably mounted on the mounting plate 63. Specifically, please refer to the figure. The mounting plate 63 is arranged at one end of the material conveying component 3 close to the outlet 32 of the material conveying component 3. This arrangement avoids the reduction of the dust collection efficiency caused by the overlong air duct 61. Detachable structures are correspondingly arranged at the top of the mounting plate 63 and the bottom of the dust storage bin 62. The types of the detachable structures include one of a sliding buckle, a snap buckle, and a plug pin. This arrangement enables the dust storage bin 62 to be conveniently detached from the mounting plate 63. On the one hand, it is convenient to maintain the internal circuit thereof, and on the other hand, it is convenient to clean in time when the dust in the dust storage bin 62 is full, so as to avoid affecting the dust collection effect.

[0049] Further, in an embodiment of the present utility model, the ash storage bin 62 includes a bin body 621 and a bin cover 622. The bin body 621 is formed with an ash outlet, and the bin cover 622 is coverably provided on the ash outlet. Please refer to Figure 1 and Figure 4 , specifically, the bin body 621 is formed with an ash storage cavity and an ash outlet. The ash outlet is communicated with the ash storage cavity, and the dust in the ash storage bin 62 can be cleaned through the ash outlet. When the dust collection component 6 is working, it is necessary to use the bin cover 621 to tightly cover and seal the ash outlet to prevent the dust from spreading from the ash outlet. Among them, a sealing ring is provided between the bin cover 621 and the side wall of the ash outlet to ensure the overall airtightness of the ash storage bin 62, thereby ensuring the negative pressure balance in the ash storage bin 62 during operation. Through this setting, it is convenient for workers to clean the inside of the ash storage bin 62, and at the same time, when the bin cover 621 is closed, it can effectively prevent dust leakage.

[0050] Please refer to Figure 1 , in an embodiment of the present utility model, a shock-absorbing layer 8 is provided between the feeding member 3 and the crushing mechanism 2. The crushing mechanism 2 will generate strong vibrations during operation, and the feeding member 3 is connected to the crusher 22. Excessive vibrations may cause fatigue effects at the connection between the crusher 22 and the feeding member 3, reducing the service life of the feeding member 3 or the crushing mechanism 2. Therefore, a shock-absorbing layer 8 is installed between the feeding member 3 and the crushing mechanism 2 to protect the connection part between the two. If the feeding member 3 and the crushing mechanism 2 are connected by bolts, this setting can effectively prevent the bolts from loosening, thereby reducing the maintenance frequency of the connection part between the feeding member 3 and the crushing mechanism 2.
