Description

Technical Field

[0001] This utility model belongs to the technical field of powder production equipment, specifically relating to a closed-loop induced draft internal circulation powder production equipment. Background Technology

[0002] Closed-loop induced draft powder production equipment is widely used in the chemical, pharmaceutical, and food industries, primarily for the drying, pulverizing, and grading of powder materials. In existing technology, this equipment typically uses a hot air blower to supply hot air into the powder dryer to achieve rapid drying of the materials. A filter screen is usually installed at the air inlet of the hot air blower to intercept dust, particles, and other impurities in the air, preventing contaminants from entering the system and affecting product quality or damaging the equipment.

[0003] However, existing technologies have the following drawbacks:

[0004] Inconvenient filter replacement: Most filters are fixed with bolts or clips, which makes it cumbersome to replace or clean them after long-term use due to dust accumulation or blockage. Therefore, there is an urgent need to design an improved closed-loop internal circulation powder production device to solve the problem of inconvenient filter replacement in the existing technology.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A closed-loop internal circulation powder production device includes a powder dryer. The air inlet of the powder dryer is connected to the air outlet of a hot air blower via a pipe. An air inlet duct is fixedly connected to the air inlet of the hot air blower via a pipe. A filter screen is detachably connected to the front end of the air inlet duct via a convenient disassembly and assembly component.

[0009] Preferably, the easy-to-assemble and disassemble component includes an arc-shaped support plate fixed to the front end of the air inlet duct, the top cross-section of which has two symmetrically arranged L-shaped structures.

[0010] Preferably, the inner bottom wall of the arc-shaped support plate has an insertion port in the middle, and an insertion block is inserted into the insertion port. The insertion block is fixed to the bottom middle of the filter screen.

[0011] Preferably, one side of the insert block is provided with a support block fixed to the middle of the bottom end of the arc-shaped support plate, and a T-shaped locking post is movably inserted on the support block. The front end of the insert block is provided with a locking hole that cooperates with the end of the T-shaped locking post.

[0012] Preferably, the front end of the support block is fixed to the T-shaped locking post by a plurality of M-shaped spring pieces arranged in a ring array.

[0013] Preferably, a handle is fixed to the front edge of the filter screen.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) When the filter screen needs to be replaced, the T-shaped locking post can be pulled to stretch and deform multiple M-shaped springs, and the end of the T-shaped locking post can be pulled out from the insertion hole at the front end of the insertion block. At this time, the filter screen can be pulled out from the arc-shaped support plate by the handle, and the insertion block can be pulled out from the insertion hole, thereby facilitating the removal and replacement of the filter screen, greatly improving the efficiency of filter screen replacement and reducing downtime.

[0026] The filter screen 22 is inconvenient to replace: The filter screen 22 is mostly fixed by bolts or clips, which makes it cumbersome to replace or clean it after long-term use due to dust accumulation or blockage. The maintenance efficiency is low.

[0027] See attached document Figure 1-5 A closed-loop internal circulation powder production device includes a powder dryer 1. The air inlet of the powder dryer 1 is connected to the air outlet of a hot air blower 2 via a pipe. An air inlet duct 21 is fixedly connected to the air inlet of the hot air blower 2 via a pipe. A filter screen 22 is detachably connected to the front end of the air inlet duct 21 via a convenient disassembly and assembly component 3.

[0028] Filter 22 is made of stainless steel.

[0029] Furthermore, such as Figure 1-5As shown, in order to facilitate the replacement of the filter 22 and reduce downtime, a convenient disassembly and assembly component 3 is provided, including an arc-shaped support plate 31 fixed to the front end of the air inlet duct 21. The top cross-section of the arc-shaped support plate 31 has two symmetrically arranged L-shaped structures. An insertion port 32 is provided in the middle of the inner bottom wall of the arc-shaped support plate 31. An insertion block 33 is inserted into the insertion port 32. The insertion block 33 is fixed to the middle of the bottom end of the filter 22. A support block 34 is provided on one side of the insertion block 33 and fixed to the middle of the bottom end of the arc-shaped support plate 31. A T-shaped locking post 35 is movably inserted on the support block 34. A locking hole 36 that matches the end of the T-shaped locking post 35 is provided at the front end of the insertion block 33. The front end of the support block 34 is fixed to the T-shaped locking post 35 by a plurality of M-shaped spring pieces 37 arranged in a ring array. A handle 221 is fixed to the front edge of the filter 22.

[0030] The three bends of the M-type spring 37 are all weakened to make the deformation smoother.

[0031] In actual use, when the filter screen 22 needs to be replaced, the T-shaped locking post 35 can be pulled to stretch and deform multiple M-shaped spring pieces 37, and drive the end of the T-shaped locking post 35 to be pulled out from the insertion hole at the front end of the insertion block 33. At this time, the filter screen 22 can be pulled out from the arc-shaped support plate 31 by the handle 221, and the insertion block 33 can be pulled out from the insertion port 32, thereby facilitating the removal and replacement of the filter screen 22, greatly improving the efficiency of filter screen 22 replacement and reducing downtime.
