Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a vibrating screen. Background Art

[0002] Vibrating screen is a filtering mechanical separation equipment used for mud solid phase treatment, which consists of a screen and a vibrator.

[0003] The Chinese utility model patent with the authorization announcement number "CN211640625U" is specifically a "vibrating screen", which removes the sediment from the plastic fragments mixed with sediment by spraying water from above the screen plate.

[0004] Although the above device can remove the mud and sand in the plastic fragments, it needs to continuously spray water on the plastic fragments mixed with mud and sand during the removal process, thus consuming a large amount of water resources. The above device does not recycle the wastewater after spraying, thus there is a problem of wasting water resources. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the utility model provides a vibrating screen, which can effectively solve the problems raised in the background technology.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The utility model provides a vibrating screen, comprising a water tank and a sieve seat elastically mounted on the top of the water tank, a sieve plate being obliquely arranged between two opposite inner side walls of the sieve seat, a vibration motor being mounted on two opposite outer side walls of the sieve seat, a circulating flushing component comprising a water pump fixedly mounted on the outer side wall of the water tank, and also comprising a group of spray heads mounted between the two opposite inner side walls of the sieve seat, located above the sieve plate, and connected to an output end of the water pump, an input end of the water pump being connected to a water suction pipe extending into an inner cavity of the water tank, an anti-clogging component comprising a filter screen cylinder rotating in the inner cavity of the water tank, an end of the water suction pipe away from the water pump extending into an inner cylinder cavity of the filter screen cylinder, and being rotatably mounted with the filter screen cylinder.

[0008] Furthermore, a water outlet pipe is installed at the water outlet at the bottom of the water tank, a valve is installed in the inner tube cavity of the water outlet pipe, and two support seats symmetrically distributed about the water outlet pipe are installed at the bottom of the water tank.

[0009] Furthermore, four vibration components are installed between the water tank and the sieve seat, and each of the vibration components includes a first fixed block, a second fixed block and a vibration spring.

[0010] Furthermore, first fixing blocks are installed at the four corners of the top of the water tank, second fixing blocks are installed at the four corners of the bottom of the sieve seat, and vibration springs are installed between the first fixing blocks and the corresponding second fixing blocks.

[0011] Furthermore, the output end of the water pump is connected to a drainage pipe that passes through the sieve seat and is connected to the input end of the group nozzle.

[0012] Furthermore, the anti-clogging component also includes a driving motor fixedly mounted on the other outer side wall of the water tank, and the output end of the driving motor is connected to a rotating shaft extending into the inner cavity of the water tank and fixedly connected to the center position of one end of the filter screen cylinder away from the water pumping pipe.

[0013] Compared with the known prior art, the technical solution provided by the utility model has the following beneficial effects:

[0014] 1. A water tank is set at the bottom of the vibrating screen to collect the sewage left after the drainage pump sprays the plastic fragments. The water in the water tank is pumped out by the water pump and then transported to the drainage nozzle through the drainage pipe to realize the recycling of water resources, which has the advantage of saving energy;

[0015] 2. In order to prevent the water in the water tank from being pumped out by the water pump and carrying mud and sand, which would block the circulating water circuit, a filter screen is set in the water tank, and the suction pipe at the input end of the water pump is extended into the filter screen, so that the water entering the filter screen and being pumped out by the suction pipe is not mixed with mud and sand, thus avoiding blocking the water circuit. At the same time, in order to prevent the mud in the water tank from adhering to and blocking the mesh holes on the surface of the filter screen, thus affecting the pumping of the suction pipe, the entire filter screen is set to rotate, and the centrifugal force generated by the rotation of the filter screen is used to throw out the small amount of mud and sand originally attached to the mesh holes of the filter screen, thus ensuring that the mesh holes on the surface of the filter screen are unobstructed.

[0026] Example 2

[0027] Reference Figure 1-4, which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: a water outlet pipe 11 is installed at the bottom water outlet of the water tank 1, and a valve 12 is installed in the inner tube cavity of the water outlet pipe 11 to facilitate regular discharge of sewage in the water tank 1. Two support seats 13 symmetrically distributed about the water outlet pipe 11 are installed at the bottom of the water tank 1. Four vibration components are installed between the water tank 1 and the sieve seat 2. The vibration components include a first fixed block 31, a second fixed block 32 and a vibration spring 33. The vibration spring 33 is repeatedly deformed to improve the stability of the sieve seat 2 during vibration. The first fixed blocks 31 are installed at the four corners of the top of the water tank 1, and the four corners of the bottom of the sieve seat 2 are A second fixed block 32 is installed at each corner, and a vibration spring 33 is installed between the first fixed block 31 and the corresponding second fixed block 32.

[0028] The remaining structures are the same as those of Example 1.

[0029] The workflow of this utility model is as follows:

[0030] First, the plastic fragments carrying the silt are continuously poured onto the sieve plate 21 of the sieve seat 2, and the vibration motors 22 on both sides are started, and the vibration springs 33 in the vibration assembly are cooperated to realize the vibration of the entire sieve seat 2 including the sieve plate 21 and the plastic fragments carrying the silt, and because the sieve plate 21 is designed to be inclined, the plastic fragments carrying the silt will gradually move toward the opening direction of the sieve seat 2;

[0031] Secondly, when the plastic fragments carrying the silt move to the group nozzle 42, the water pump 41 is started, and the water in the filter screen cylinder 51 and the water in the water tank 1 is extracted through the water pumping pipe 44, and is transported to the group nozzle 42 through the drainage pipe 43, and the plastic fragments carrying the silt on the screen plate 21 are washed by the group nozzle 42, accompanied by synchronous vibration, so that the silt is washed by the water flow and falls from the mesh on the screen plate 21 into the water tank 1, forming a circulating flushing system;

[0032] Finally, in order to prevent the silt that falls into the water tank 1 from being extracted by the suction pipe 44 and then clogging the circulating flushing system, the suction pipe 44 is extended into the filter screen cylinder 51. Through the filtration of the filter screen cylinder 51, large particles of silt are blocked outside the filter screen cylinder 51, so that the water entering the filter screen cylinder 51 and extracted by the suction pipe 44 is not mixed with silt. In order to prevent the silt in the water tank 1 from adhering to and blocking the mesh holes on the surface of the filter screen cylinder 51 and affecting the pumping of the suction pipe 44, the drive motor 52 is started, and the filter screen cylinder 51 is driven to rotate as a whole through the rotating shaft 53. The centrifugal force generated by the rotation of the filter screen cylinder 51 is used to throw out the small amount of silt originally attached to the mesh holes of the filter screen cylinder 51, thereby ensuring that the mesh holes on the surface of the filter screen cylinder 51 are unobstructed.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
