Technical Field
[0001] The utility model belongs to the technical field of coal gangue screening, in particular to a particle size vibration screening device for coal gangue ceramsite production. Background Art
[0002] Gangue ceramsite is a new type of environmentally friendly material. It is made from the waste slag discharged during coal mining, namely gangue, after artificial and mechanical selection, crushing, screening, and expansion. It has the characteristics of light weight, high porosity, and excellent permeability, and has been widely used in the market. In the process of producing gangue ceramsite, in order to ensure the uniformity of the particle size and production efficiency of the ceramsite, it is often screened for particle size.
[0003] At present, when screening the gangue particles, some of the gangue particles form agglomerates because the transportation between the screenings needs to maintain humidity, resulting in the inability to screen normally. They are discharged together with the remaining defective gangue particles and impurities, resulting in a large amount of waste and not conducive to efficient production operations.
[0004] In order to solve the above problems, the present application proposes a particle size vibration screening device for producing coal gangue ceramsite. Utility Model Content

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:
[0007] The utility model discloses a particle size vibration screening device for producing gangue ceramsite, comprising: a screening drum and a feeding hopper installed at the upper end thereof, the feeding hopper is used to gather the gangue particles inside the screening drum; an inner screen plate for screening the gangue particles is arranged inside the screening drum, a guide platform for guiding the gangue particles is arranged on one side of the inner part of the screening drum, and the bottom of the guide platform is also used to break up the gangue particles agglomerated due to moisture-preserving transportation; a side seat is arranged on the outer side of the screening drum, an outer screen plate for secondary screening of the gangue particles is arranged inside the side seat, and a return hopper for recovering the gangue particles to the inner part of the screening drum is arranged at the lower end of the side seat.
[0008] Furthermore, a material guide plate is provided at the lower end of the outer sieve plate, and the upper end of the outer sieve plate is connected to the interior of the screening cylinder through a side notch.
[0009] Furthermore, a side box for installing an electric vibrator is provided on the other side of the screening drum, and the inner side of the side box is connected to the interior of the screening drum through an open groove.
[0010] Furthermore, an inner ring frame for sealing the open groove is arranged at the lower end of the inner sieve plate, and an outer arc plate connected to the electric oscillator is arranged on one side of the inner ring frame.
[0011] Furthermore, a storage box for collecting gangue particles is provided at the bottom of the screening cylinder, and a limiting ring frame docking with the screening cylinder is provided at the upper end of the storage box.
[0012] Furthermore, a transfer block rotatably connected to the upper end of the storage box is provided at the lower end of the limiting ring frame, and the upper end of the storage box protrudes inwardly to abut against the bottom of the screening cylinder to form a seal.
[0013] Furthermore, an outer side of the bottom of the screening cylinder is provided with an external thread for spirally mounting the storage box.
[0014] The utility model has the following beneficial effects:
[0015] The utility model utilizes the screening cylinder and the guide table to gather the coal gangue particles of the material, and then utilizes the electric oscillator to drive the inner screen plate to shake up and down, so that the particles agglomerated due to moisture retention hit the bottom of the guide table to form a dispersion effect, and then are normally screened downward to the internal storage of the storage box. Compared with the existing screening method, the waste of coal gangue particles can be effectively avoided, the normal screening and processing of qualified particles can be guaranteed, and it is conducive to the use of large-scale and efficient production operations;
[0016] The utility model can perform secondary screening on some of the screened defective coal gangue particles and form a recovery effect by adding a return hopper at the bottom of the guide plate and connecting its bottom to the screening cylinder, so as to prevent the defective coal gangue from being discharged with qualified particles. After this arrangement, only the defective particles and impurities can be discharged, which effectively guarantees the quality of the produced products and improves the use effect of the equipment.

[0030] The present embodiment provides a vibrating screening mechanism after the moisturizing conveying of the coal gangue, which causes the coal gangue particles to collide with the bottom of the guide platform 10 by means of vibration, so that the coal gangue particles agglomerated due to moisturizing are broken up for screening operations, and at the same time, the outer screen plate 4 is used to perform secondary screening on the discharged coal gangue particles, so that the qualified coal gangue particles that are entrained are screened out and collected through the return hopper 14, and finally the unqualified coal gangue particles are discharged, thereby forming an efficient screening operation while reducing cost losses.
[0031] Among them, a material guide plate 5 is provided at the lower end of the outer sieve plate 4, and the upper end of the outer sieve plate 4 is connected to the inside of the screening cylinder 1 through the side slot 6. The large particle materials isolated under the inner sieve plate 11 are discharged outward through the side slot 6, and a secondary screening operation is formed when passing through the outer sieve plate 4.
[0032] A side box 7 for installing an electric vibrator is provided on the other side of the screening drum 1. The inner side of the side box 7 is connected to the interior of the screening drum 1 through an open groove. The side box 7 is also used to protect the electric vibrator.
