Description

Technical Field

[0001] This utility model relates to the field of dust control technology, specifically a transition device for stone crushing. Background Technology

[0002] A jaw crusher is a mechanical device used to crush large materials into smaller pieces. It is commonly used in industries such as mining, metallurgy, and construction. In particular, when used in the mining and construction industries, it is mainly used for crushing stone. However, since the crushing method is generally to crush the stone by impacting it with external force, it is easy to generate some fine particles and dust particles during the crushing process. When the stone falls out of the lower opening of the jaw crusher, some dust particles are carried by the material and fall onto the ground or conveyor belt. This causes the relative positions of the synchronously moving materials to change, resulting in dust leaking out between the materials. Under the reaction force of the material and the conveyor belt or the ground, the dust is stirred up. This causes dust to be stirred up on the ground or at the inlet of the equipment for subsequent processing of crushed stone, affecting the working environment of the workers.

[0003] Therefore, a transfer device for stone crushing is needed to solve the dust problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a transfer device for stone crushing.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a stone crushing adapter includes a housing, on which a through channel runs vertically through is provided, and a right opening runs through the side wall of the through channel to the right. Several nozzles are arranged around the upper opening of the through channel and facing into the opening. The nozzles are connected to an external positive air pressure pipe. The lower opening of the through channel is connected to an external negative air pressure pipe. A support frame is provided on the inner wall of the through channel, and the upper surface of the support frame is on the same plane as the bottom wall of the right opening.

[0006] By adopting the above technical solution, after the crushed stone enters through the opening at the top of the through-channel, airflow is introduced into the through-channel using several nozzles at the top opening to prevent dust particles from flying out again after entering the through-channel. Then, negative pressure is applied at the bottom opening of the through-channel using an external negative air pressure pipe, thereby forming a downward airflow in the through-channel. The support frame then blocks the stone of appropriate particle size and discharges it from the right opening, while dust particles with a diameter smaller than the aperture of the support frame are carried by the airflow and pass through the support frame, and are discharged from the bottom opening of the through-channel. This separates the dust from the stone particles of appropriate size, reduces dust when the crushed stone falls, and also reduces dust in the subsequent stone transportation process.

[0007] The present invention is further configured such that: the housing includes a collection shell, an upper shell, and a lower shell continuously arranged vertically; the collection shell is fixedly connected to the upper surface of the upper shell; the upper shell is detachably connected to the upper surface of the lower shell; the collection shell has a vertically penetrating storage cavity inside; the lower end of the upper shell has an upwardly penetrating discharge cavity that communicates with the lower opening of the storage cavity; the discharge cavity extends to the right near the lower opening and penetrates the upper shell; the lower shell has a vertically penetrating through cavity; and the space between the upper surface of the lower shell and the space where the discharge cavity extends to the right near the lower opening forms a right opening.

[0008] By adopting the above technical solution and utilizing the detachable connection between the upper and lower shells, the through channel can be divided into two parts, and the right opening can be exposed. After a day of work, it can be disassembled for cleaning and maintenance of the interior, preventing the inner wall of the through channel from being impacted by stones and developing pits or cracks that go unnoticed after a certain period of operation. It also allows for the replacement of upper shells with different discharge chamber sizes to accommodate different stone diameters (mainly when handling different sizes of crushed stone particles, the upper shell can be replaced in time to increase the applicability of the equipment).

[0009] The present invention is further configured such that: the cross-sectional area of ​​the storage cavity first increases and then decreases from bottom to top, and the inner wall of the opening of the storage cavity changes in an arc-shaped transition.

[0010] By adopting the above technical solution, the curvature of the inner wall of the receiving cavity is changed so that when the nozzle blows air into the receiving cavity, the direction of the airflow passing through the stone can be changed along the inner wall of the receiving cavity and enter the discharge cavity. This prevents the airflow blown out by the nozzle from flowing out from the upper opening of the receiving cavity, and prevents dust from being carried out by the airflow from flowing out from the upper opening of the receiving cavity, thereby further reducing dust.

[0011] The present invention is further configured such that: an installation groove is provided at the opening position of the through cavity; the support frame is fitted into the installation groove and abuts against the lower end of the upper shell; a plurality of installation blocks are fixedly connected to the side walls of the upper shell and the lower shell, and the installation blocks on the upper shell and the lower shell are arranged opposite each other in pairs; holes are provided on the installation blocks, and the two opposite installation blocks are fixedly connected by bolts.

[0012] By adopting the above technical solution, the support frame is installed in the upper and lower shells. After the upper and lower shells are removed, the support frame can also be removed for cleaning or replacement. Before installing the upper and lower shells as one unit, the support frame is first placed in the mounting slot, and then the force of locking the upper and lower shells is used to fix the support frame in the mounting slot, thereby achieving installation and increasing stability.

[0013] The present invention is further configured such that: a side baffle is fixedly connected to the front and rear positions of the right side wall of the upper shell near the right opening, and an extension plate is fixedly connected to the right side wall of the lower shell near the upper position, and the upper surface of the extension plate abuts against the lower surface of the side baffle.

[0014] By adopting the above technical solution and utilizing the integrated structure of the upper and lower shells, the two side baffles on the upper shell and the protruding plate on the lower shell can be spliced ​​together to form an outwardly protruding platform. When the stone flows out from the right opening, it will enter the platform and then be thrown out. This makes it convenient to place a transfer device or conveyor belt, or the next processing equipment, under the platform, preventing the stone from falling directly down the side walls of the upper and lower shells and failing to be transferred smoothly to the next equipment.

[0015] The present invention is further configured such that the upper surface of the lower shell and the lower surface of the upper shell are horizontal and then inclined downward from left to right, and the nozzle and the discharge chamber are both arranged on the inclined downward slopes of the upper shell and the lower shell.

[0016] By adopting the above technical solution, utilizing the bent surface structure of the upper shell and the structure of the upper surface of the lower shell cooperating with the upper shell, the bottom wall of the right opening formed by the discharge chamber is inclined downward. On the one hand, the stone material in the discharge chamber can flow directly out from the right opening and the platform under its own gravity. On the other hand, combined with the structural setting of the installation groove, the support frame and the bottom wall of the right opening are always kept at the same level, ensuring that the stone material can flow out normally along the right opening.

[0017] The present invention is further configured such that: a support frame for supporting the lower shell is provided at the lower end of the lower shell, and a square-to-circular joint communicating with the through cavity is fixedly connected at the lower opening position of the through cavity.

[0018] By adopting the above technical solution, the lower shell is supported by a support frame, thereby supporting the lower shell. Then, a square-to-circular structure can be installed below the lower shell. The square-to-circular structure connects the through channel with a rectangular cross-section to the external negative air pressure pipe with a circular structure. The negative air pressure pipe is also equipped with a dust filter (such as the dust filter in application number: CN200710127042.1, or other filters used to filter dust in the air) to collect the sucked-out dust.

[0019] In summary, this utility model has the following beneficial effects: By using several nozzles arranged in a circular array at the opening of the receiving cavity, airflow is introduced into the through channel from the opening of the receiving cavity. Then, negative pressure is applied into the through channel through the square-to-round section, so that the airflow in the through channel is vertically downward and carries away the dust carried in the crushed stone, reducing dust. At the same time, the detachable connection between the upper and lower shells and the structure with the support frame set between the upper and lower shells can not only replace or disassemble the support frame for cleaning when it is damaged or blocked, but also allow the discharge cavity to be exposed and cleaned.

A support frame 22 is provided on the inner wall of the through-channel, and the upper surface of the support frame 22 is on the same plane as the bottom wall of the right opening. The housing includes a collection shell 11, an upper shell 14, and a lower shell arranged vertically in succession. 18. The collecting shell 11 is fixedly connected to the upper surface of the upper shell 14. The upper shell 14 is detachably connected to the upper surface of the lower shell 18. The collecting shell 11 has a vertically penetrating storage cavity 13. The lower end of the upper shell 14 has an upwardly penetrating discharge cavity 17 that communicates with the lower opening of the storage cavity 13. The discharge cavity 17 extends to the right near the lower opening and penetrates the upper shell 14. The lower shell 18 has a vertically penetrating through cavity 20. The space between the upper surface of the lower shell 18 and the rightward extension of the discharge cavity 17 near the lower opening forms a right opening.

[0024] like Figures 1 to 2 As shown, the cross-sectional area of ​​the storage cavity 13 increases first and then decreases from bottom to top, and the inner wall of the opening of the storage cavity 13 changes in an arc shape.

[0025] like Figures 1 to 5 As shown, a mounting groove 23 is provided at the opening of the through cavity 20. The support frame 22 is fitted into the mounting groove 23 and abuts against the lower end of the upper shell 14. Several mounting blocks 15 are fixedly connected to the side walls of the upper shell 14 and the lower shell 18, and the mounting blocks 15 on the upper shell 14 and the lower shell 18 are arranged opposite each other. The mounting blocks 15 have holes, and the two opposite mounting blocks 15 are fixedly connected by bolts. A side baffle 16 is fixedly connected to the front and rear positions of the right side wall of the upper shell 14 near the right opening. The right side wall of the lower shell 18 is fixedly connected to the side baffle 16.
