Abstract
Description
Technical Field
[0001] This utility model relates to the field of high zirconium brick production technology, specifically a dust prevention system for feeding and unpacking in the production of electrofused refractory bricks. Background Technology
[0002] In the production process of fused refractory bricks, powder is an important raw material, and these powders are usually transported and stored in bags.
[0003] When using fused refractory brick raw material powder, it is necessary to unpack it. The unpacking process mainly relies on gravity to throw the bag containing the fused refractory brick raw material powder onto a sharp object below. The impact force causes the sharp object to puncture the bag and spill the powder. However, this operation is prone to generating dust, which not only pollutes the working environment and endangers the health of operators, but also leads to waste of materials. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a dust prevention system for feeding and unpacking electric fused refractory bricks, so as to solve the problems of large pollution and waste of powder dust during the unpacking process of existing electric fused refractory brick raw material powder.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust prevention system for unpacking high zirconium brick powder, comprising an unpacking chamber, a dust suction chamber provided at the upper end of one side of the unpacking chamber, the dust suction chamber being connected to the unpacking chamber, a dust suction device for absorbing dust materials being provided inside the dust suction chamber, a pulse device for dust flushing being provided at the upper end of the dust suction device, a recovery chamber being provided directly below the dust suction chamber, and the lower end of the dust suction chamber being connected to the recovery chamber.
[0006] As a preferred embodiment of this utility model, the dust collection device includes a centrifugal fan and a dust bag, with the dust bag located at the lower end of the centrifugal fan and the pulse device located directly above the dust bag.
[0007] As a preferred technical solution of this utility model, a cabinet door is provided on one side of the unpacking compartment.
[0008] As a preferred embodiment of this utility model, the cabinet door is equipped with an electronic control mechanism for controlling the opening and closing of the cabinet door.
[0009] As a preferred embodiment of this utility model, the lower end of the unpacking compartment is provided with an unpacking buffer hopper, which is located in the pit.
[0010] Compared with the prior art, the beneficial effects of this utility model are: This dust prevention system for feeding and unpacking in the production of electrofused refractory bricks seals the unpacking chamber, absorbs the powder through a dust suction device during the unpacking process, and then blows the adsorbed material into the recycling chamber through a pulse device. This can prevent dust leakage and flying, protect the health of operators, and at the same time realize the recycling and reuse of powder, save costs and avoid waste. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments (for ease of description and understanding, hereinafter referred to as...). Figure 1 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0015] Please see Figure 1-2 This utility model provides a technical solution: a dust prevention system for unpacking and feeding materials in the production of fused refractory bricks, including an unpacking chamber 1. A dust suction chamber 2 is provided at the upper end of one side of the unpacking chamber 1, and the dust suction chamber 2 is connected to the unpacking chamber 1. A dust suction device 3 for absorbing dusty materials is provided inside the dust suction chamber 2. The dust suction device 3 includes a centrifugal fan 31 and a dust collection bag 32. The dust collection bag 32 is located at the lower end of the centrifugal fan 31, and a pulse device 4 is located at the upper end of the centrifugal fan 31 and below the dust collection bag 32. A recovery chamber 5 is located directly above and below the suction chamber 2. The lower end of the suction chamber 2 is connected to the recovery chamber 5. After the bag is broken, the escaped dust is sucked into the dust collection bag 32 for filtration by the centrifugal fan 31. The dust adheres to the outside of the dust collection bag 32. The pulse device 4 includes an electromagnetic pulse valve and an air tank. By opening the electromagnetic pulse valve, the compressed air in the air tank is ejected, which washes the dust adhering to the outside of the dust collection bag 32 into the recovery chamber, thereby realizing the recovery of dust.
[0016] Furthermore, to prevent dust from escaping, a cabinet door 6 is provided on one side of the unpacking compartment 1.
[0017] Furthermore, in order to facilitate the control of the opening and closing of the cabinet door 6, an electric control mechanism 7 is provided on the cabinet door 6. The electric control mechanism 7 mainly controls its opening and closing through an electric telescopic rod.
[0018] In order to facilitate the concentrated falling of the raw material powder of fused refractory bricks into the pit, the lower end of the unpacking chamber 1 is provided with an unpacking buffer hopper 8, which is located in the pit 9.
[0019] In use: After the bag containing the raw material powder of fused refractory bricks enters the unpacking chamber 1 through the transport device, the chamber door 6 is closed, and the claws on the transport device are released. The bag hits the sharp part located below, and the bag breaks. The raw material powder of fused refractory bricks falls into the pit 9 through the unpacking buffer hopper 8. The escaped dust is adsorbed onto the surface of the dust collection bag 32 by the centrifugal fan 31. After the centrifugal fan 31 stops, the pulse device 4 starts and sprays gas to blow the dust attached to the surface of the dust collection bag 32 into the recovery chamber 5 for collection.
[0020] This invention effectively controls the leakage and dispersion of dust during the unpacking process, reducing the dust concentration in the working environment to below the national standard, protecting the health of operators, reducing pollution to the surrounding environment, and preventing waste of powder due to dust.
[0021] The parts of the utility model not described in detail are prior art. Although embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model.
