Description

Technical Field

[0002] Blowers are a common gas delivery equipment, widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings. Due to different working environments, dust in the air inhaled after long-term work is easy to adhere to the blower blades, impellers and the inside of the casing, which increases the noise of the blower and has an adverse effect on the precision parts of the blower. In order to improve the stable operation of the blower, it is necessary to remove dust from the gas inhaled by the blower. For example, the dust-proof structure of a blower with application number "201820986175.8" is mainly composed of a pipe body, a filter and an exhaust port. When the utility model is used, it effectively improves the cleanliness of the filtered air, reduces the wear of the impeller of the blower, and extends the service life of the blower through a combination of multiple groups of primary air filters and conical air filters. A cleaning brush is provided to facilitate manual control cleaning when dust accumulates on the air filter, so that the conical air filter maintains a good filtering effect. No driving mechanism and energy consumption are required, the structure is simple, and it is easy to use and maintain.

[0003] When the prior art is in use, a diamond-shaped net is installed at the air inlet of the blower. When the blower is running, particulate matter in the air is filtered through the diamond-shaped filter net to prevent the particulate matter from entering the blower and affecting the operation of the fan blades.

[0004] However, in actual use, after long-term use, particles and dust will accumulate on the diamond net, resulting in reduced working efficiency of the blower, and each time a blockage occurs, it cannot be discovered in time, resulting in reduced work efficiency. Utility Model Content

[0011] Beneficial Effects

[0012] The utility model provides a dustproof structure for a blower. It has the following beneficial effects: the dustproof structure of the blower cooperates with an auxiliary pipe, a clamping plate and a clamping spring, and long-term filtering causes particles and dust to accumulate on the filter screen. When a blockage occurs, the internal pressure is too large, so that the sealing block is moved out of the auxiliary pipe, so that the auxiliary pipe is opened, and the gas is filtered through the auxiliary filter screen, so that it is avoided that the filter is not filtered after the blockage, which makes it convenient for workers to perform subsequent maintenance, improves work efficiency, and solves the problem that long-term filtering in the prior art will cause blockage and reduce work efficiency when it is used.

[0020] However, in actual use, after long-term use, particles and dust will accumulate on the diamond net, resulting in reduced working efficiency of the blower, and each time a blockage occurs, it cannot be discovered in time, resulting in reduced work efficiency.

[0021] In view of this, the utility model provides a dustproof structure for a blower, which solves the problem that during actual use, particles and dust will accumulate on the diamond net during long-term use, resulting in reduced working efficiency of the blower, and each time a blockage occurs, it cannot be discovered in time, resulting in reduced work efficiency.

[0022] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle.

[0024] In the specific implementation process, it is worth pointing out that, with the cooperation of the clamping plate 12, the clamping spring 15 and the filter screen 6, long-term filtering will cause particles and dust to accumulate on the filter screen 6. When blockage occurs, it will cause excessive internal pressure, so that the sealing block 16 is moved out of the auxiliary pipe 7, so that the auxiliary pipe 7 is opened, and the gas is filtered through the auxiliary filter screen 19, avoiding the failure of filtering after blockage, making it convenient for workers to perform subsequent maintenance and improving work efficiency;

[0025] Furthermore, the top of the clamping plate 12 is fixedly connected to a limiting column 17, the outer wall of the limiting column 17 is movably connected to the inner wall of the auxiliary pipe 7, and one end of the limiting column 17 is fixedly connected to a clamping block 18;

[0026] In the specific implementation process, it is worth pointing out that, with the cooperation of the limiting column 17, the auxiliary tube 7 and the clamping block 18, the limiting column 17 is used to prevent the clamping plate 12 from moving out of the auxiliary tube 7 when moving, and the clamping plate 12 is used to fix the limiting column 17, so that it is more stable when moving;

[0027] Furthermore, one end of the auxiliary pipe 7 extending to the interior of the fixed plate 9 is fixedly connected to a connecting rod 8, and the outer wall of the connecting rod 8 is fixedly connected to the outer wall of the filter screen 6;

[0028] In the specific implementation process, it is worth pointing out that, under the cooperation of the auxiliary pipe 7, the connecting rod 8 and the filter screen 6, the auxiliary pipe 7 is fixed by using the connecting rod 8, so that the auxiliary pipe 7 and the filter screen 6 are fixed;

[0029] Specifically, when the dustproof structure of the blower is used, after the dustproof structure is installed on the blower, after a long period of filtration, dust will accumulate on the filter 6 and increase the internal pressure, thereby squeezing the sealing block 16 and opening the auxiliary pipe 7, so that the gas inhaled by the blower will pass through the auxiliary filter 19 to remove particulate matter in the gas, thereby avoiding a reduction in the filtering effect when the filter 6 is blocked.

[0030] Embodiment 2: By Figure 1-4 It can be seen that the bottom of the fixed plate 9 is pressed against the top plate 14, the bottom of the top plate 14 is fixedly connected to the telescopic column 13, the bottom of the telescopic column 13 is pressed against the spring 11, the bottom of the spring 11 is pressed against the fixed column 10, and the bottom of the fixed column 10 is fixedly connected to the top of the mounting plate 3;

[0031] In the specific implementation process, it is worth pointing out that, with the cooperation of the top plate 14, the spring 11 and the mounting plate 3, when installing the filter screen, the top plate 14 is pressed against the outer wall of the fixing plate 9, so that the telescopic column 13 squeezes the spring 11, so that the device is more convenient to disassemble and install;

[0032] Furthermore, the outer wall of the filter screen 6 is provided with filter paper 5, and the outer wall of the filter paper 5 is movably connected to the inner wall of the fixed plate 9;

[0033] In the specific implementation process, it is worth pointing out that, with the cooperation of the filter paper 5 and the filter screen 6, the filter screen 6 and the filter paper 5 are used to remove the particles in the gas, making it cleaner during filtration;

[0034] Specifically, on the basis of the above embodiment, the dustproof device is installed at the air inlet of the blower, and the dust and particulate matter are removed by the filter 6. During installation and replacement, the mounting plate 3 is removed to remove the filter 6. After replacement, the top plate 14 drives the telescopic column 13 to squeeze the spring 11, thereby fixing the filter 6, making it more convenient to replace.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
