Description

Technical Field

[0001] The utility model relates to the technical field of sand and gravel screening, in particular to a square swing screen system. Background Art

[0002] In the field of sand and gravel screening, traditional screening equipment often has problems such as low screening efficiency, low screening accuracy, and severe dust during the screening process. These problems not only affect the screening effect, but also bring great pollution to the working environment.

[0003] The square swing screen is an important equipment for sand and gravel screening. However, the discharge pipe connected to the discharge bin of the current square swing screen is generally vertically downward. When screening sand and gravel, a storage mechanism is fixed under each discharge pipe to receive sand and gravel of different sizes. When a large amount of sand and gravel screening is required, more storage mechanisms are required, and the equipment cost is high. At the same time, a large amount of dust particles will be generated when screening sand and gravel. These dust particles will be scattered in the air, which will bring great pollution to the workshop and have an adverse effect on the health of the operator. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a square swing screen system, which can screen sand and gravel into different mesh sizes and then discharge them from different discharge pipes.

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-3 As shown, the embodiment of the utility model provides a square swing screen system, comprising:

[0024] A plurality of vertically arranged square swing screen bodies 1, the square swing screen bodies 1 are fixed in a frame 2 through a plurality of universal shafts 18, a plurality of outlet pipes 3 are provided on a multi-stage unloading bin of the square swing screen body 1, each outlet pipe 3 is connected to a discharge pipe 4, and the multi-stage unloading bin also has a discharging portion 5;

[0025] A plurality of transmission lines 6 are arranged transversely, and the discharge pipe 4 is located directly above each transmission line 6;

[0026] A dust suction pipe 7 is connected to a dust suction fan 8. A plurality of dust suction hoses are fixed below the dust suction pipe 7. The dust suction hoses are fixed in the discharging portion 5. The end of the dust suction pipe is connected to a dust removal device through a dust removal fan.

[0027] The process of the utility model when in use is as follows: unscreened sand and gravel enter from the feed port of the square swing screen body 1, and after being screened by the square swing screen, sand and gravel of different particle sizes will be discharged from different discharge pipes 4. Since different discharge pipes 4 correspond to different transmission lines 6, sand and gravel of different particle sizes will be screened out and flow into different transmission lines. When the sand and gravel are discharged from the discharge pipe 4, at the same time, the dust suction fan 8 of the dust suction pipe 7 starts to perform dust suction action, absorbs the fine sediment dispersed in the air, and discharges it from the end of the dust suction pipe 7 into the dust removal device 19 for unified treatment (the dust removal device is connected to a cyclone dust collector or a bag dust collector). Since the dust suction hose is connected below the dust suction pipe 7, and the dust suction hose is connected to the discharging part 5, even when the discharging part 5 swings with the square swing screen, there will be no interference between the dust suction hose and the dust suction hose.

[0028] Furthermore, the end of the vacuum hose is connected to a vacuum hood 9. Specifically, in order to better absorb the dust particles scattered in the air, the utility model connects the end of the vacuum hose to a vacuum hood 9, so that the adsorption area is larger and the dust particles are better adsorbed.

[0029] Furthermore, the square swing screen body 1 is fixedly connected to a support platform 10. By fixing the square swing screen on a support platform 10, the discharge pipe 4 has a larger space, making it easier to align with the transmission line 6 when installing it.

[0030] Furthermore, the disbursement portion 5 is a support plate 11, a connection hole 12 is provided on the support plate 11, a buffer sleeve 13 is fixed to the inner wall of the connection hole 12, and the dust suction hose passes through the buffer sleeve 13. Specifically, the disbursement portion 5 of the utility model is a support plate 11, and the connection hole 12 in the support plate 11 is provided with a buffer sleeve 13, so that when the support plate 11 vibrates, it collides and rubs with the dust suction hose, which can also better extend the life of the dust suction hose.

[0031] Furthermore, a base 14 is fixed on the square rocking screen body 1, a fixing plate 15 is connected to the base 14 through a screw 17, and the universal shaft 18 is connected to the fixing plate 15. Specifically, the utility model fixes a base 14 on the square rocking screen body 1, a screw 17 passes through the base 14, the screw 17 is fastened by a nut 16, and a fixing plate 15 is provided on the top of the screw 17, and the universal joint at the bottom of the universal shaft 18 is connected to the fixing plate 15. With this structure, if the inclination angle of the square rocking screen needs to be finely adjusted, it is only necessary to adjust the angle of the screw 17, and the adjustment is convenient and quick.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
