Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a screening device for limestone production. Background Art

[0002] Limestone is a common ore whose main component is calcium carbonate. It is used in many industrial processes, including building materials, metallurgy, chemical industry, agriculture and other fields. The production of limestone mainly includes mining, crushing, grinding and other steps.

[0003] In the process of producing limestone, the raw materials need to be screened first. However, after the raw materials are shaken by the outside world, a large amount of smoke and dust will be generated, which will not only affect the working environment of personnel, but also affect the air environment. In the screening process, the filter must not only be installed stably, but also be easy for subsequent personnel to disassemble. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a screening device for limestone production.

[0006] The auxiliary component includes a dust cover, which is arranged on the upper surface of the screening cylinder. A handle is fixedly connected to the middle of the upper surface of the dust cover, and both sides of the lower surface of the dust cover are fixedly connected to resistance rods, and the bottom end of the resistance rod is arranged on the upper surface of the screening filter.

[0007] Through the above technical scheme, when the limestone raw material enters the interior of the screening cylinder, the personnel place the dust cover on the upper surface of the screening cylinder to seal the screening cylinder to prevent the limestone raw material from generating a large amount of dust and affecting the air environment during the subsequent vibration screening process, and a resistance rod is provided at the bottom of the dust cover. When the dust cover is installed, the resistance rod is located on the upper surface of the screening filter, and the screening filter can be fixed in conjunction with the overlap block. While improving the stability of the screening filter during operation, it is also convenient for personnel to disassemble and replace the screening filter. When replacement is required, the personnel take out the dust cover, and the resistance rod is separated from the surface of the screening filter, so that the personnel can replace the screening filter.

[0008] As a further improvement of the above solution, both sides of the top of the screening drum are fixedly connected with extension seats, and the upper surface of the extension seat is fixedly connected with a positioning rod.

[0009] Through the above technical solution, one end of the positioning rod is fixed to the surface of the extension seat, and the other end passes through the dust cover.

[0010] As a further improvement of the above solution, the positioning rod passes through the dust cover, and the outer surface of the positioning rod is threadedly connected with a hexagonal bolt.

[0011] Through the above technical solution, personnel fix the extension seat and the dust cover by tightening the hexagonal bolts, and indirectly complete the fixation between the dust cover and the screening cylinder, thereby ensuring that the dust cover will not fall off during the subsequent vibration screening process.

[0012] As a further improvement of the above solution, vibration motors are fixedly mounted on both sides of the outer surface of the screening drum by bolts, and a first disc is fixedly connected to the bottom end of the screening drum.

[0013] Through the above technical solution, the vibration motor utilizes the rotational motion of the motor to generate vibration, and the vibration drives the screening drum to shake, so that the limestone raw material located on the surface of the screening filter can be screened through the screening filter.

[0014] As a further improvement of the above solution, amplitude springs are fixedly connected to the four sides of the lower surface of the first disk, and the bottom end of the amplitude spring is fixedly connected to the second disk.

[0015] Through the above technical solution, the amplitude spring is set to provide a certain amplitude space for the screening drum when it vibrates, ensuring that the vibration motor can drive the screening drum to shake normally.

[0016] As a further improvement of the above solution, the upper surface of the second disc is fixedly connected with limiting rods, the number of the limiting rods is three, and the limiting rods pass through the first disc.

[0017] Through the above technical solution, the setting of the limit rod can achieve the limiting effect, so that the screening drum will not tilt when shaking, thereby improving the safety protection effect of the screening drum.

[0018] As a further improvement of the above solution, a pipeline groove is provided in the middle of the surface of the first disc and the second disc, and a discharge pipe is provided inside the pipeline groove, and the discharge pipe is matched with the discharge port.

[0019] Through the above technical solution, the setting of the discharge pipe is mainly used to transport the screened limestone raw materials and collect them in a unified manner to facilitate the subsequent personnel to carry out the next step of operation.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The utility model arranges auxiliary components, and when the limestone raw material enters the interior of the screening cylinder, the personnel installs the dust cover to seal the screening cylinder, so as to prevent the limestone raw material from generating a large amount of dust and affecting the air environment during the subsequent vibration screening process; a resistance rod is arranged at the bottom of the dust cover, and when the dust cover is installed, the resistance rod will be located on the upper surface of the screening filter, and the screening filter can be fixed with the overlap block to improve the stability; when the personnel remove the dust cover and the resistance rod is separated from the surface of the screening filter, the personnel can replace the screening filter, which is convenient for the personnel to disassemble.
