[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figures 1 to 3 As shown, in an illustrative embodiment of the circulating wind dust removal and impurity removal device of the vibrating screen of the utility model, the circulating wind dust removal and impurity removal device of the vibrating screen includes a dust collector 1 and a dust removal fan 2.

[0034] The vibrating screen includes a frame 4, a screen box 5 and a vibration motor 6. The screen box 5 is installed on the frame 4 by elastic parts such as springs and shock-absorbing rubber. The vibration motor 6 is installed on the screen box 5. The screen box 5 is provided with a screen plate 7. The screen plate 7 has screen holes and divides the space in the screen box 5 into upper and lower layers. The material is put into the screen box 5. Under the vibration action of the vibration motor 6, the material is spread on the screen plate 7. The part larger than the screen hole slides along the screen plate 7 and is discharged from the second discharge port 52, and the part smaller than the screen hole falls through the screen hole into the space below the screen plate 7 and is discharged through the first discharge port 51.

[0035] The dust collector 1 is located below the screen box 5 of the vibrating screen, and includes a dust removal box body 11 and a dust removal bag 12 installed in the dust removal box body 11. The bottom end of the dust removal bag 12 is connected to the dust discharge port 13 set at the bottom of the dust removal box body 11, so that the internal space of the dust removal bag 12 is not connected to the internal space of the dust removal box body 11.

[0036] The dust removal fan 2 has a fan air outlet 21 and a fan return air outlet 22. A first air inlet 53 and a first air outlet 54 are respectively arranged at both ends of the screen box 5. The first air outlet 54 is connected with an air outlet pipe 8. The air outlet pipe 8 extends into the dust removal box body 11 and is connected to the internal space of the dust removal bag 12. The second air outlet 14 arranged on the dust removal box body 11 is connected to the fan return air outlet 22 through the return air pipe 9, and the fan air outlet 21 is connected to the first air inlet 53.

[0037] The airflow blown out by the dust removal fan 2 is blown into the screen box 5 from one end through the first air inlet 53, and the incoming airflow flows along the screen box 5 to the first air outlet 54 at the other end for discharge. The dust and debris in the screen box 5 are discharged through the first air outlet 54 together with the airflow, and enter the dust bag 12 through the air outlet 8. Since the dust bag 12 is air permeable, the airflow penetrates the dust bag and enters the return air duct 9 through the second air outlet 14, thereby flowing back to the dust removal fan 2, and the dust and debris remain inside the dust bag 12. Since only the bottom end of the dust bag 12 is connected to the dust outlet 13, the dust and debris remaining in the dust bag 12 fall to the bottom end and are discharged through the dust outlet 13, and the discharged dust and debris can fall into the collection container.

[0038] In the above-mentioned schematic embodiment, the dust collector 1 in the circulating wind dust removal and impurity removal device of the vibrating screen is composed of only a dust removal box 11 and a dust removal bag 12. The dust and debris in the air flow are separated and discharged by filtering. The overall structure is simple, easy to install and maintain, and compared with the Shaklon dust collector, it has a very small size and can be placed under the screen box 5, utilizing the floor space of the vibrating screen itself, thereby not increasing the floor space of the equipment extra; the airflow generated by the dust removal fan 2 blows through the screen box 5 and the dust collector 1 in turn, and then returns to the dust removal fan 2, and the airflow circulates, and the airflow flowing back to the dust removal fan 2 itself has a certain flow rate, so that the dust removal fan 2 does not need a large power output to make the airflow blow into the screen box 5 again at the required speed, thereby improving the efficiency of the dust removal fan 2, and the airflow circulates in the closed structure, which can ensure that all dust and debris can be sent to the dust collector, avoiding the outflow of airflow and dust leakage, and solving the problem that the current vibrating screen dust removal and impurity removal system occupies a large space, is cumbersome to install and wastes the fan efficiency.

[0039] In some embodiments, the dust removal bag 12 is installed on the screen box 5 .

[0040] Due to the effects of static electricity, dust and debris are easily adhered to the inner wall of the dust bag 12, so that they cannot fall and are discharged through the dust outlet 13. The screen box 5 vibrates during operation, and the dust bag 12 installed thereon vibrates synchronously, shaking off the adhered dust and debris, thereby ensuring that all dust and debris can be discharged, and at the same time, it can also prevent the adhesion of dust and debris from reducing the air permeability of the dust bag 12, thereby preventing the efficiency of air circulation from being reduced.

[0041] In some embodiments, the dust removal box 11 is fixed on the screen box 5, so that the dust removal box 11 can vibrate synchronously with the screen box 5, and then the dust bag 12 vibrates with the dust removal box 11 to shake off dust and debris. The dust removal box 11 is installed on the screen box 5, which also facilitates the dust collector 1 to be fixed under the screen box 5.

[0042] In some embodiments, the dust removal fan 2 is mounted on the frame 4, and the return air duct 9 is a hose. Since the dust removal fan 2 is on the fixed frame 4, and the dust collector 1 is located on the vibrating screen box 5, the hose can move with the vibration to keep the dust collector 1 connected to the dust removal fan 2.

[0043] In some embodiments, the vibration motor 6 of the vibrating screen is mounted on the dust removal box 11, and the dust removal box 11 is integrally connected to the screen box 5. Since the dust removal box 11 is installed on the screen box 5 and occupies the space below the screen box 5, the vibration motor 6 is installed on the dust removal box 11 so that the vibration motor 6 is also located below the screen box 5, which can further improve the utilization rate of the space below the screen box 5. In addition, a force guide plate is generally installed on the screen box 5 of the vibrating screen, and the vibration motor 6 is generally not directly installed on the screen box 5, but installed on the force guide plate, thereby increasing the distance between the vibration motor 6 and the screen box 5, thereby enhancing the amplitude of vibration. The vibration motor 6 is installed on the dust removal box 11, so that the dust removal box 11 acts as a force guide plate, increases the distance between the vibration motor 6 and the screen box 5, and increases the amplitude of vibration.

[0044] In some embodiments, the width of the dust removal box 11 gradually decreases from top to bottom, which not only reduces the volume of the dust removal box 11, but also enables the vibration motor 6 installed on the outer wall of the dust removal box 11 to be on an inclined plane, thereby enabling the screen box 5 to reciprocate in the up and down directions and the front and back directions, ensuring the flattening and vibration of the material. The dust removal box 11 can further simulate the role of the guide plate.

[0045] In some embodiments, the second air outlet 14 is located at the top of the dust removal box 11, so as to keep it away from the dust exhaust port 13 to prevent the airflow from affecting the discharge of dust and debris.

[0046] In some embodiments, the screen box 5 includes a bottom box 55 with an open top, and a dust cover 56 is installed on the bottom box 55 to close the top of the bottom box 55. An air inlet cover 57 and an air collecting cover 58 are installed on the ports arranged at both ends of the dust cover 56, respectively, the first air inlet 53 is located on the air inlet cover 57, and the first air outlet 54 is located on the air collecting cover 58.

[0047] The screen box 5 of the existing vibrating screen is generally a trough-shaped structure with an open top. By adding a dust cover 56 and installing an air inlet cover 57 and an air collecting cover 58 at both ends, a circulating wind dust removal and impurity removal device can be installed on the existing vibrating screen, which is convenient for modifying the existing equipment. In order to ensure the input of materials, a feed port 59 is set on the side of the dust cover 56 close to the air inlet cover 57.

[0048] In some embodiments, the bottom box 55 has a sieve plate 7, and a first discharge port 51 is provided at one end of the bottom box 55 close to the air collecting hood 58, and the first discharge port 51 is located below the sieve plate 7. The bottom plate of the air collecting hood 58 is a perforated plate 50, which is connected to the sieve plate 7, and a second discharge port 52 is provided at one end of the air collecting hood 58 away from the bottom box 55, and an air guide hood 81 provided on the air outlet pipe 8 covers the perforated plate 50.

[0049] The screen box 5 of the existing vibrating screen generally has an opening at one end, and the screen plate 7 in the screen box 5 is flush with the opening, so that the material moving along the surface of the screen plate 7 can be discharged from the screen box 5 through the opening. After the screen box 5 is installed with the air collecting cover 58, the orifice plate 50 is connected to the screen plate 7, so that the material leaving the screen plate 7 then moves to the orifice plate 50. Since the air guide cover 81 covers the orifice plate 50, the air flow passes through the orifice plate 50 and enters the air outlet 8, and can flow through the material moving on the orifice plate 50, thereby further blowing off and sucking away the dust and debris adhering to the surface of the material, further improving the dust removal effect and improving the cleanliness of the discharged material.

[0050] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0051] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
