Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a workshop dust removal device. Background Art

[0002] Flour is a powder made from wheat, also known as wheat flour. According to the protein content in the flour, it can be divided into high-gluten flour, medium-gluten flour, low-gluten flour and gluten-free flour. During the production and processing of flour, a large amount of dust will be filled in the workshop. If this dust encounters an open flame, it will explode. Therefore, flour workshops are generally equipped with dust removal devices.

[0003] The most commonly used dust removal device in flour workshops is a bag combined with a negative pressure fan for dust removal, and a filtering structure is also set between the dust collecting bag and the fan to prevent dust from entering the fan. However, during the use of the filtering structure, the filter screen will be blocked, thereby affecting the negative pressure wind force, so it needs to be disassembled and cleaned regularly. The existing dust removal device cannot clean the filter screen in real time, and when disassembling the filter assembly, a large number of bolts need to be removed, which affects the disassembly and cleaning efficiency. Therefore, the utility model proposes a workshop dust removal device. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 4 As shown, it relates to a workshop dust removal device, including a base plate 1, a dust collecting bucket 2 is fixedly connected to one side of the upper surface of the base plate 1 through a vertical rod, a cone bucket 3 is fixedly connected to the bottom of the dust collecting bucket 2, a cloth bag 16 is installed at the bottom of the cone bucket 3, an air inlet pipe 4 is fixed to the side wall of the bottom end of the dust collecting bucket 2, and an air outlet pipe 5 is fixed to the side wall of the top end of the dust collecting bucket 2, a sleeve 6 is slidably sleeved on the surface of the air outlet pipe 5, and a support assembly 7 is fixedly connected between the outer wall of the sleeve 6 and the outer wall of the dust collecting bucket 2, a filter assembly 8 is provided inside the air outlet pipe 5, and a cleaning assembly for cleaning the filter assembly 8 is provided inside the sleeve 6, and a negative pressure fan 14 connected with the sleeve 6 is fixed on the upper surface of the base plate 1.

[0023] like Figure 1-Figure 2 As shown, a hose 15 is fixedly connected to the air inlet of the negative pressure fan 14 , and the hose 15 is fixedly connected to the sleeve 6 .

[0024] When the negative pressure fan 14 is started, negative pressure can be drawn into the dust collecting bucket 2 through the hose 15, the sleeve 6 and the air outlet pipe 5, so that the dust in the workshop can be sucked into the dust collecting bucket 2 through the air inlet pipe 4.

[0025] In this embodiment, a sealing ring may be provided at the joint between the inner wall of the sleeve 6 and the outer wall of the air outlet pipe 5 to increase the sealing performance of the connection between the sleeve 6 and the air outlet pipe 5 .

[0026] like Figure 1-Figure 2 As shown, the air inlet pipe 4 and the air outlet pipe 5 are both located in the tangent direction of the dust collecting bucket 2.

[0027] When the dust enters the dust collecting bucket 2 , most of the dust will move along the inner wall of the dust collecting bucket 2 , and then fall into the cloth bag 16 along the inner wall of the dust collecting bucket 2 .

[0028] like Figure 1-Figure 3As shown, the support assembly 7 includes a transverse tube 72 fixed to the outer wall of the sleeve 6, a transverse rod 71 is slidably connected inside the transverse tube 72, and a spring 73 is fixedly connected to the transverse rod 71 and the inner wall of the transverse tube 72, and one end of the transverse rod 71 located outside the transverse tube 72 is fixedly connected to the outer wall of the dust collecting bucket 2.

[0029] The natural state of the spring 73 is a contracted state, so the cross tube 72 can be pulled to fit on the surface of the cross bar 71, thereby pulling the sleeve 6 to fit on the surface of the air outlet pipe 5, thereby realizing the connection between the air outlet pipe 5 and the sleeve 6. When the sleeve 6 needs to be removed from the surface of the air outlet pipe 5, the sleeve 6 can be directly pulled to separate from the air outlet pipe 5.

[0030] like Figure 1-Figure 4 As shown, the filter assembly 8 includes an inner frame plate 81 located inside the air outlet duct 5 and an outer frame plate 82 located outside the air outlet duct 5 . A connecting rod 83 is commonly connected between the inner frame plate 81 and the outer frame plate 82 . A filter screen 84 is fixed in the middle of the inner frame plate 81 .

[0031] When the air inside the dust collecting bucket 2 is discharged along the air outlet pipe 5 , the filter screen 84 can prevent dust from entering the air outlet pipe 5 .

[0032] like Figure 3 As shown, an inner ring plate 61 is fixed to the inner wall of the sleeve 6, and two sides of the outer frame plate 82 are respectively fitted with the inner ring plate 61 and the end surface of the air outlet pipe 5.

[0033] When the sleeve 6 is fixed on the surface of the air outlet pipe 5 under the pulling of the support assembly 7, the inner ring plate 61 can just squeeze and fix the filter assembly 8 inside the air outlet pipe 5. When the sleeve 6 is separated from the air outlet pipe 5, the filter assembly 8 can be directly pulled out from the inside of the air outlet pipe 5.

[0034] like Figure 1-Figure 3 As shown, the cleaning assembly includes a support rod 9 fixed to the inner wall of the sleeve 6, and the other end of the support rod 9 is fixedly connected to a fixed shaft 10, the surface of the fixed shaft 10 is rotatably connected to a fan blade 11, the middle surface of the fan blade 11 is fixedly connected to a rotating shaft 12, the other end of the rotating shaft 12 is fixedly connected to a brush 13, and the brush 13 is in contact with the filter 84.

[0035] When air passes through the inside of the sleeve 6, the flowing air drives the fan blades 11 to rotate, and the fan blades 11 then drive the rotating shaft 12 and the brush 13 at one end of the rotating shaft 12 to rotate, and the brush 13 can clean the dust blocked on the surface of the filter screen 84 in real time.

[0036] Working principle: Start the negative pressure fan 14, use the hose 15, sleeve 6 and outlet pipe 5 to draw negative pressure inside the dust collection bucket 2, then move the device in the workshop, use the air inlet pipe 4 to suck the suspended dust in the workshop into the dust collection bucket 2, and the dust falls into the bag 16 along the inner wall and cone bucket 3 inside the dust collection bucket 2. In this process, the filter 84 will block the dust from entering the outlet pipe 5 and the sleeve 6, and during the air flow, it will drive the fan blades 11 to rotate, and the fan blades 11 will drive the shaft 12 and the brush 13 at one end of the shaft 12 to rotate, and the brush 13 can clean the dust blocked on the surface of the filter 84 in real time. When the filter assembly 8 needs to be replaced, pull the sleeve 6 to separate from the outlet pipe 5, then pull out the filter assembly 8 inside the outlet pipe 5, replace the new filter assembly 8 and insert it into the outlet pipe 5, then loosen the sleeve 6, and under the pull of the spring 73, the sleeve 6 is re-sleeved on the surface of the outlet pipe 5.

[0037] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
