[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] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1 and Figure 2 As shown, an expansion chamber comprises: a chamber body 1 and a filter screen 2 and a blade assembly arranged inside the chamber body 1.

[0025] A feed port 8 is provided at the lower end of the silo body 1, and material dust enters the interior of the silo body 1 through the feed port 8. A flange 9 is provided at the lower end of the silo body 1, and the flange 9 is connected to the flange 9 on the feeding device through a bolt rod.

[0026] Three filter screens 2 are arranged in sequence from bottom to top at the lower part of the silo body 1. The three filter screens 2 are arranged on the inner wall of the silo body 1. The three filter screens 2 have a certain distance in the vertical direction. After the material dust enters the interior of the silo body 1, it first passes through the three filter screens 2 in sequence, and the three filter screens 2 preliminarily block the material dust. After the material dust is stable, it automatically falls back, and the material dust is preliminarily removed.

[0027] Three blade groups are arranged on the upper part of the silo body 1. The three blade groups have the same structure and are arranged from bottom to top. The blade groups include: a plurality of dust-blocking blades 3 arranged at equal angles. The dust-blocking blades 3 are used to block the dust of the material for a second time. The dust of the material blocked by the dust-blocking blades 3 is automatically removed after being stabilized, thereby improving the effect of removing the dust of the material.

[0028] A vibrator 4 is arranged on the outer wall of the bin body 1, and the vibrator 4 directly vibrates the outer wall of the bin body 1. The bin body 1 transmits the vibration force to the dust-blocking blades 3, and indirectly provides vibration force to the dust-blocking blades 3 and the filter screen 2 to remove the dust of the materials on the dust-blocking blades 3 and the filter screen 2.

[0029] During operation, the gas passes through the filter 2, which blocks the dust of the material in the gas. Part of the dust of the material falls back after being blocked, and the other part of the dust of the material continues to rise with the gas and passes through the dust blocking blades 3 in each blade group in turn. The dust blocking blades 3 block the dust of the material again, and part of the dust of the material falls back after being blocked, and the other part of the dust of the material stays on the dust blocking blades 3. The dust blocking blades 3 are driven to vibrate by the vibrator 4, and the dust of the material staying on the dust blocking blades 3 falls along the blades. There is no need to disassemble the dust blocking blades 3 for cleaning. The equipment can work continuously for a long time, effectively improving the production efficiency.

[0030] The dust-blocking blade 3 is fan-shaped as a whole. According to the cylindrical structure design of the upper part of the silo body 1, the top surface of the dust-blocking blade 3 can be one of a plane and a curved surface. The outer side of the dust-blocking blade 3 is connected to the inner wall of the silo body 1, and the outer side of the dust-blocking blade 3 is higher than the inner side of the dust-blocking blade 3. Since the silo body 1 is vertically arranged as a whole, the dust-blocking blade 3 has a certain slope, that is, an acute angle is formed between the dust-blocking blade 3 and the inner wall of the silo body 1. When the vibrator 4 starts to drive the dust-blocking blade 3 to vibrate through the silo body 1, the material dust on the top surface of the dust-blocking blade 3 gradually slides from the inner side of the dust-blocking blade 3, that is, the material dust moves toward the axial position of the silo body 1, ensuring that the connection between the dust-blocking blade 3 and the inner wall of the silo body 1 will not cause material dust to be stuck.

[0031] Among them, the acute angle between the dust-blocking blade 3 and the inner wall of the silo is between 30°-60°. Preferably, the acute angle between the dust-blocking blade 3 and the inner wall of the silo is between 45°. On the basis of ensuring that the dust-blocking blade 3 blocks the dust of the material, it is ensured that when the vibrator 4 vibrates, the dust of the material on the dust-blocking blade 3 can be vibrated off as much as possible.

[0032] Two adjacent dust-blocking blades 3 in the same blade group do not contact each other, that is, a certain space is provided between the two adjacent dust-blocking blades 3. A part of the material dust is blocked on the lower dust-blocking blades 3, and the other part of the material dust is blocked when passing through the upper dust-blocking blades 3. The setting of the multi-layer blade group can reduce the burden of a single blade group in blocking material dust and improve the material dust removal effect.

[0033] In addition, a material drop channel 5 is formed in the middle part of the blade group, and the axial direction of the material drop channel 5 is consistent with the axial direction of the silo body 1. The material dust on the top surface of the dust-blocking blade 3 slides to the material drop channel 5 first, and is prevented from falling into the top surface of the lower dust-blocking blade 3 again, thereby being quickly discharged from the silo body 1, thereby improving the material dust removal efficiency.

[0034] The vertical projection of several blade groups is an annular surface, that is, a part of the material dust is blocked on the lower dust-blocking blades 3, and the other part of the material dust will still be blocked when passing through the upper dust-blocking blades 3. The setting of multiple blade groups can reduce the burden of blocking material dust by a single blade group and improve the material dust removal effect. While ensuring the passage of gas, the dust-blocking blades 3 in multiple blade groups can block material dust to the greatest extent.

[0035] The upper part of the silo body 1 is set to be cylindrical, and the upper part of the silo body 1 is mainly installed with a blade group, so the upper part of the silo body 1 can be set to be cylindrical. Since the diameter of the feed port 8 is smaller than the inner diameter of the silo body 1, the lower part of the silo body 1 is set to be cone-shaped, and the tip of the cone faces the ground, which helps the dust of the material dropped in the silo body 1 to be discharged from the feed port 8 and will not be retained near the feed port 8.

[0036] An exhaust port is provided at the top of the silo 1. When gas continuously enters at the feed port 8, the internal pressure of the silo 1 needs to be balanced, and the gas after the dust of the material is filtered out is discharged through the exhaust port. A dust bag 7 is provided at the exhaust port, wherein the dust bag 7 and the exhaust port can be sealed and connected together by a snap connection, which is convenient for later replacement and cleaning. The functional characteristics of the dust bag are existing technical means, so the dust bag 7 has a certain filtering effect, and the gas is further purified when passing through the dust bag 7.

[0037] It should be noted that the dust bag 7 is not used as a main filtering structure, but as an auxiliary filtering structure for the dust blocking blades 3 and the filter screen 2.

[0038] A maintenance window 6 is provided on the upper portion of the bin body 1 , and the maintenance window 6 is provided on the outer peripheral side of the bin body 1 , so that when it is necessary to maintain the internal parts of the bin body 1 , it is more convenient for maintenance personnel to operate.

[0039] The filter screen 2 is arranged on the inner wall of the silo body 1. The filter screen 2 is cone-shaped as a whole, and the tip of the cone points to the feed port 8. When the material dust falls, the filter screen 2 can be prevented from blocking the material dust from falling as much as possible. It should be noted that the filter screen 2 is always in a taut state. At this time, the vibrator 4 can drive the dust blocking blades 3 and the filter screen 2 to vibrate at the same time through the silo body 1, thereby further accelerating the material dust to fall to the feed port 8.

[0040] When the utility model is used, the gas passes through the three filter screens 2 in sequence, and the three filter screens 2 respectively block the material dust in the gas. Part of the material dust is blocked by the filter screens 2 and then falls back, and the other part of the material dust continues to rise with the gas and passes through the dust blocking blades 3 in each blade group in sequence. Further, part of the material dust stays on the dust blocking blades 3 of the lower layer, and the other part of the material dust is blocked when passing through the upper dust blocking blades 3. Part of the material dust falls back after being blocked, and the other part of the material dust stays on the dust blocking blades 3. When the dust blocking blades 3 and the filter screen 2 need to be cleaned, the vibrator 4 is used to drive the dust blocking blades 3 to vibrate, and the material dust staying on the dust blocking blades 3 falls back along the blades to the position of the feed inlet 8 for centralized collection.

[0041] In summary, the material dust is blocked multiple times by multiple filter nets 2 and multi-layer blade groups, and the material dust automatically falls back after being stabilized, which effectively improves the removal effect of the material dust. Moreover, the vibrator 4 drives the dust blocking blades 3 to vibrate, and the dust blocking blades 3 stay and fall back along the blades. There is no need to disassemble the dust blocking blades 3 for cleaning. The equipment can work continuously for a long time, effectively improving the production efficiency.

[0042] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0043] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the utility model.
