Technical Field

[0001] The utility model provides a high-negative-pressure large-scale dust collector shell structure, and relates to the technical field of dust collectors. Background Art

[0002] The biggest feature of high negative pressure dust collector is high negative pressure. The dust collector shell is prone to large deformation under high negative pressure, which may cause damage to sheet metal and other components. Controlling and strengthening the deformation under high negative pressure is the guarantee for improving the safety and performance of the dust collector.

[0003] In the traditional dust collector design and development process, the thickness of the sheet metal and the position of the reinforcing ribs are often designed based on their own experience. The machines made in this way often have big problems and uncertain factors. First, the machine produces a large amount of deformation, which affects the safety and life of the machine; second, under the action of large deformation, the sheet metal rebounds and produces abnormal noise; third, the sheet metal thickness of the machine is too thick, and the reinforcing ribs are too many, which wastes material use and increases weight and cost.

[0004] Therefore, it is necessary to provide a high negative pressure large dust collector shell structure with reasonable rib discharge. Utility Model Content

[0005] In order to overcome the shortcomings of the existing dust collector shell with excessive and complicated reinforcement ribs, resulting in waste of materials, or incorrect placement of the reinforcement ribs, resulting in large deformation, the utility model provides a high-negative-pressure large dust collector shell structure with reasonable reinforcement rib arrangement.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the utility model provides the following technical solutions: a high-negative pressure large dust collector shell structure, including a mounting plate, an outer shell and a collection frame, the outer shell is mounted on the mounting plate, the collection frame is placed in the outer shell, and also includes first reinforcing ribs and second reinforcing ribs, seven first reinforcing ribs are fixedly connected to each outer wall of the outer shell, the spacing between the upper and lower first reinforcing ribs is 165 mm, and multiple second reinforcing ribs are fixedly connected to the inner wall of the outer shell.

[0007] In one embodiment, the first reinforcing rib is a hollow long rectangular strip, and the second reinforcing rib is a solid long rectangular strip.

[0008] In one embodiment, the length, width and thickness of the first reinforcing rib are 60*40*3.2 mm.

[0009] In one of the embodiments, it also includes a ventilation pipe fixedly connected to the outer shell, the ventilation pipe is communicated with the outer shell, an external thread is arranged on the ventilation pipe, a fixing ring is slidably arranged on the ventilation pipe, the external thread is threadedly connected to the fixing ring, and a plurality of mounting holes are opened on the fixing ring.

[0010] In one of the embodiments, it also includes guide blocks installed on both sides of the shell, and two guide rods are slidably arranged on the guide blocks. One end of the two guide rods is fixedly connected to a wedge block, and the other end of the two guide rods is fixedly connected to a pull ring, and elastic parts are wound around the two guide rods.

[0011] In one of the embodiments, each edge of the top of the collecting frame is provided with an inclined surface sloping downward toward the center.

[0012] In one of the embodiments, a sealing gasket is fixedly connected to the inner ring at the top of the housing.

[0013] In one of the embodiments, a plurality of third reinforcing ribs are fixedly connected to the mounting plate and the housing.

[0014] Compared with the prior art, the high negative pressure dust collecting shell structure provided by the embodiment of the utility model has the following advantages: 1. The strength of the shell is enhanced by the first reinforcing ribs and the second reinforcing ribs. Under the negative pressure of 20000pa, the deformation of the shell is 0.995mm, which greatly reduces the deformation from the original deformation of 6.784mm to less than 1mm, thereby achieving the effect of reasonably discharging the reinforcing ribs and reducing the deformation of the shell.

[0015] 2.

[0016] 3. Insert the dust guide pipe into the outer shell from the top. At this time, the dust guide pipe pushes the wedge blocks on both sides to slide away from each other, so that the elastic part is compressed and deformed. After the dust guide pipe and the outer shell are connected, the elastic part pushes the wedge blocks to slide and reset, clamp and limit the dust guide pipe, so as to achieve the effect of fixedly connecting the dust guide pipe and the outer shell.

DETAILED DESCRIPTION

[0022] 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 in 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.

[0023] Example 1: A high negative pressure large dust collector housing structure, see Figure 1 and Figure 2 As shown, it includes a mounting plate 1, an outer shell 2 and a collecting frame 5. The outer shell 2 is installed on the mounting plate 1 by welding. The collecting frame 5 for collecting dust is placed in the outer shell 2. It also includes a first reinforcing rib 3 and a second reinforcing rib 4. Seven first reinforcing ribs 3 distributed up and down are fixedly connected to each outer side wall of the outer shell 2 by welding. The spacing between the upper and lower first reinforcing ribs 3 is 165 mm. The first reinforcing rib 3 is a hollow long rectangle, which saves material and makes the outer shell 2 stronger. The length, width and thickness of the first reinforcing rib 3 are 60*40*3.2mm. A plurality of second reinforcing ribs 4 are fixedly connected to the inner wall of the outer shell 2 by welding. The second reinforcing rib 4 is a solid long rectangle to prevent the second reinforcing rib 4 from deforming under negative pressure.

[0024] When the outer shell 2 is performing negative pressure dust collection, the first reinforcing rib 3 and the second reinforcing rib 4 enhance the strength of the outer shell 2. Under a negative pressure of 20,000 Pa, the deformation of the outer shell 2 is 0.995 mm, which greatly reduces the deformation from the original deformation of 6.784 mm to less than 1 mm. When the outer shell 2 is under negative pressure, the dust is collected in the collection frame 5.

[0025] Example 2: Based on Example 1, refer to Figure 3 As shown, it also includes a ventilation pipe 7 fixedly connected to the side wall of the shell 2 by welding. The ventilation pipe 7 is used to connect the negative pressure equipment. The ventilation pipe 7 is connected to the shell 2. An external thread 8 is provided on the ventilation pipe 7. A fixing ring 6 is slidably provided on the ventilation pipe 7. The external thread 8 is threadedly connected to the fixing ring 6. Four mounting holes 601 are opened on the circumference of the fixing ring 6.

[0026] When it is necessary to connect the negative pressure device, rotate the fixing ring 6 along the external thread 8 to move the fixing ring 6 away from the outer shell 2, then connect the through pipe of the negative pressure device with the ventilation pipe 7, and insert the bolts into the mounting hole 601 and the through pipe of the negative pressure device, and use nuts to fix the bolts, thereby realizing the connection between the through pipe of the negative pressure device and the ventilation pipe 7, and starting the negative pressure device to form negative pressure in the outer shell 2 for dust collection.

[0027] See also Figure 3 and Figure 4 As shown, it also includes guide blocks 9 installed on both sides of the upper part of the shell 2 by bolt connection, and two guide rods 10 are horizontally slidably arranged on the guide blocks 9. One end of the two guide rods 10 is fixedly connected to a wedge block 11 by welding, and the other end of the two guide rods 10 is fixedly connected to a pull ring 12 by welding. Elastic members 13 are wound around the two guide rods 10, and the elastic members 13 are used to push the wedge blocks 11 on both sides closer to each other.

[0028] When it is necessary to connect the dust guide pipe to the shell 2, the dust guide pipe is inserted into the shell 2 from the top. At this time, the dust guide pipe pushes the wedge blocks 11 on both sides so that the wedge blocks 11 on both sides slide toward the side away from each other through the guide rod 10 along the guide block 9. At this time, the elastic member 13 is compressed and deformed by force. After the dust guide pipe is connected to the shell 2, the elastic member 13 pushes the wedge block 11 to slide and reset, so that the wedge blocks 11 on both sides can jointly clamp and limit the dust guide pipe to prevent the dust guide pipe from being separated from the shell 2 when introducing dust; when it is necessary to pull the dust guide pipe out of the shell 2, first pull the pull rings 12 on both sides so that the pull rings 12 drive the wedge blocks 11 away from each other through the guide rod 10, so that the wedge blocks 11 are separated from the limit on the dust guide pipe, and then the dust guide pipe can be slid upward from the shell 2 to be pulled out.

[0029] See also Figure 2 and Figure 3 As shown, each edge of the top of the collecting frame 5 is provided with an inclined surface 14 inclined downward toward the center; a sealing gasket 15 is fixedly connected to the inner ring of the top of the outer shell 2 by bonding; and a plurality of third reinforcing ribs 16 are fixedly connected to the mounting plate 1 and the outer shell 2 by welding.

[0030] The setting of the inclined surface 14 prevents the dust entering the outer shell 2 from remaining on the top edge of the collecting frame 5, and the dust slides into the collecting frame 5 through the inclined surface 14; the sealing gasket 15 can make the connection between the dust guide pipe and the outer shell 2 tighter to prevent dust from leaking; the third reinforcing rib 16 makes the connection strength between the mounting plate 1 and the outer shell 2 higher, so that the bottom of the outer shell 2 is not easily deformed under high negative pressure.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
