[0002] In the process of preparing coated sand, various raw materials such as sand, clay and organic matter may need to be processed and mixed. These raw materials may generate dust during the processing, so dust removal measures need to be taken to prevent the impact of dust on the working environment and workers.

[0003] After being used for a certain period of time, the existing dust removal structure used for coated sand will accumulate a lot of dust and impurities inside. When replacing the filter screen or filter element, it is usually necessary to shut down the machine. On the one hand, it will affect the dust removal effect of the coated sand. On the other hand, if the coated sand dust removal equipment is also shut down, it will cause the problem of too low coated sand production, which makes it inconvenient to easily replace the filter screen without affecting the production of coated sand.

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1-Figure 5As shown, a dust removal device for producing coated sand which is easy to replace the filter screen comprises a dust removal box 1, a partition plate 2 is fixedly connected at the center of the inner wall of the dust removal box 1, an air intake assembly is arranged on the rear side of the dust removal box 1, a plurality of support plates 7 are fixedly connected to the left and right inner walls of the dust removal box 1 respectively, the support plate 7 is U-shaped, and the same filter layer 6 is arranged on two support plates 7 on the same plane, a sealing door 8 is installed on the front side wall of the dust removal box 1, a plurality of tightening assemblies are arranged on the rear side wall of the sealing door 8, and two fans 15 are installed on the right side wall of the dust removal box 1, and the fans 15 are connected to the inner cavity of the dust removal box 1.

[0023] like Figure 2 and Figure 3 As shown, the air intake assembly includes an air intake pipe 3 arranged on the rear side of the dust removal box 1, and two branch pipes 4 are fixedly connected to the side wall of the air intake pipe 3. The branch pipes 4 are both connected to the inner cavity of the dust removal box 1, and a control valve 5 is installed at the connection between the upper air intake pipe 3 and the branch pipe 4.

[0024] The control valve 5 is a three-way valve, which is a common industrial valve used to control the flow direction of a fluid (liquid or gas). It usually has one inlet and two outlets (or vice versa), and can switch the flow direction of the fluid between the two outlets, or guide the fluid from the two inlets into one outlet.

[0025] like Figure 5 As shown, the tightening assembly includes a round rod 9 fixedly connected to the rear side wall of the sealing door 8, the side wall of the round rod 9 is movably connected to a cylinder 10, the end face of the cylinder 10 is fixedly connected to a top plate 12, the top plate 12 is against the filter layer 6, and the side wall of the cylinder 10 is equipped with a spring 11.

[0026] Specifically, each filter layer 6 corresponds to two tightening components, which are used to tighten the filter layer 6. On the one hand, this reduces the gap between the filter layer 6 and the inner wall of the dust removal box 1 to increase the filtering effect. On the other hand, it can prevent the filter layer 6 from shaking due to other factors such as the vibration of the fan 15 during the dust removal process.

[0027] like Figure 4 and Figure 5 As shown, two pulleys 13 are symmetrically mounted on the bottom surface of the filter layer 6 , and the pulleys 13 are movably connected to the support plate 7 .

[0028] Specifically, the pulley 13 corresponds to the grooves on the support plate 7, which makes it easy to accurately place the filter layer 6 at a suitable position in the dust removal box 1, and also makes it easy to remove the filter layer 6 from the dust removal box 1, so as to achieve the purpose of convenient replacement.

[0029] like Figure 4As shown, a baffle 14 is fixedly connected to the top surface of the filter layer 6. When too much dust is collected on the filter layer 6, in order to prevent the dust from being scattered in the dust removal box 1 when it is taken out for cleaning, the baffle 14 can be used to enclose the dust, thereby improving the practicality of the filter layer 6.

[0030] like Figure 2 As shown, a sealing ring 16 is fixedly connected to the rear side wall of the sealing door 8 , and the sealing ring 16 abuts against the end surface of the dust removal box 1 .

[0031] The sealing ring 16 can fill the gap between the door and the device to prevent fluid or gas leakage; at the same time, it can reduce the erosion and damage to the interior of the dust removal box 1 caused by external environmental factors (such as moisture, dust, chemicals, etc.) and extend its service life.

[0032] The working principle of the utility model is as follows: the dust or powder generated in the production process of coated sand will be transported to the dust removal box 1 through the air intake pipe 3. After the dust or powder is filtered by the multiple filter layers 6, the dust is adsorbed on the filter layer 6. When the filter layer 6 needs to be replaced, the dust can be discharged into another cavity by rotating the control valve 5. At this time, the sealing door 8 can be opened, and the filter layer 6 can be taken out for cleaning or replacement, and then placed in the dust removal box 1. When the sealing door 8 is closed, the top plate 12 supports the filter layer 6, and the force of the spring 11 is used to make the filter layer 6 and the inner wall of the dust removal box 1 fit together, so as to avoid the problem of incomplete dust filtration.

[0033] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
