Description

Technical Field

[0001] The utility model relates to the technical field of sand suction machine silencing, and more specifically to an outlet type silencer. Background Art

[0002] The vacuum sand suction machine is a dust removal device used for pneumatic pipeline transportation of bulk granular materials. It is mainly composed of a sand falling tank equipped with a sand suction pipe and an air suction pipe, a filter element back-blowing cyclone dust collector and a water ring vacuum pump fixedly installed in a square frame. When the vacuum sand suction machine is operating, the pump at its exhaust port will produce continuous noise. In actual operation, the vibration effect caused by this kind of noise will have a negative impact on the surrounding environment and the working people, so the noise needs to be processed to a certain extent.

[0003] At present, the common method for dealing with the noise of the vacuum sand suction machine pump is to directly install a silencer. However, due to the space occupied by the pump itself, the position and the size of the silencer, the actual silencing effect of the silencer is difficult to achieve the expected level.

[0004] Therefore, in view of this, the existing structure is studied and improved, and a lead-out silencer is provided to achieve a purpose with greater practical value. Utility Model Content

[0007] 2. Technical solution

[0010] A reflecting slope is arranged inside the muffler guide tube, and an elastic support block group is arranged between the reflecting slopes, and the muffler guide tube, the elastic support block group and the reflecting slope form an integrated structure;

[0011] The silencer chamber is fixed to one end of the silencer guide pipe away from the silencer joint. A multi-layer placement bracket is clamped inside the silencer chamber, and a silencer porous sponge is arranged on the multi-layer placement bracket.

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] In this solution, when the vacuum sand suction machine is operating, the silencer connector of the device is fixed at the position where the pump generates noise. At this time, the noise passes through the silencer connector and is introduced into the silencer guide tube, and is reflected multiple times by the reflective slope. Eventually, most of the noise reaches the inside of the silencer chamber and is absorbed by the silencer porous sponge inside the silencer chamber. During the entire silencer process, the noise is transmitted by the silencer connector and the silencer guide tube, which can effectively reduce the occupation of the space around the pump by the silencer structure, and minimize the impact of the space occupied by the pump itself, the position and the size of the silencer on the silencer. Then, the large-volume silencer chamber absorbs the noise, which can effectively ensure the actual effect of the silencer. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0030] Example:

[0031] See also Figure 1-6 A lead-out silencer includes a silencer joint 1, a silencer guide pipe 2 is installed at one end of the silencer joint 1, and threaded holes 101 are provided on the sides of the silencer joint 1 and the silencer guide pipe 2, and a docking bolt 102 is threadedly connected through the threaded hole 101. The threaded hole 101 and the docking bolt 102 can form a stable docking between the silencer joint 1 and the silencer guide pipe 2, thereby avoiding the possibility of noise leaking from the silencer joint 1 and the silencer guide pipe 2.

[0032] See also Figure 1 and Figure 2Specifically, the silencer joint 1 includes a head 103 and a short-distance pipe 104, and an inner interface piece 105 and an outer interface piece 106 are fixedly provided at one end of the short-distance pipe 104, and the inner interface piece 105 and the outer interface piece 106 are respectively fixed to the inner side and the outer side of the short-distance pipe 104. The head 103 can ensure that the entire silencer joint 1 fits well with the noise generating place, and then the short-distance pipe 104 cooperates with the inner interface piece 105 and the outer interface piece 106, which can maximize the air tightness of the short-distance pipe 104 and the silencer guide pipe 2 when they are connected, thereby reducing the possibility of noise leakage.

[0033] See also Figure 1 , Figure 3 and Figure 4 , and also includes a reflecting slope 3, which is arranged inside the silencer guide tube 2, and an elastic support block group 4 is arranged between the reflecting slope 3 and the reflecting slope 3. The silencer guide tube 2, the elastic support block group 4 and the reflecting slope 3 form an integrated structure. The reflecting slope 3 is an inclined structure, which can control the rebound direction of the noise to a certain extent, and finally make most of the noise pass through the silencer guide tube 2 and reach the silencer chamber 5.

[0034] Specifically, the muffler guide pipe 2 includes a narrow-mouth pipe 201 and a wide-mouth pipe 202 , and the narrow-mouth pipe 201 and the wide-mouth pipe 202 are of an integrated structure.

[0035] Specifically, the length of the wide-mouth pipe 202 is six times that of the narrow-mouth pipe 201. The length and type of the narrow-mouth pipe 201 and the wide-mouth pipe 202 are controlled to ensure that the noise reaches the reflection area as much as possible, thereby controlling the noise to be reflected from the reflection area to the silencing chamber 5 as soon as possible and processed, thereby improving the efficiency of noise processing.

[0036] Specifically, the elastic support block group 4 is a multi-stage structure made of rubber material, and the elastic support block group 4 and the reflective slope 3 are both arranged on the inner side of the wide-mouthed pipe 202. The elastic force of the elastic support block group 4 can reduce the vibration amplitude of the noise, thus achieving preliminary treatment of the noise.

[0037] See also Figure 1 , Figure 5 and Figure 6 , a silencing chamber 5 is fixed to the end of the silencing guide pipe 2 away from the silencing joint 1, and a multi-layer mounting bracket 6 is clamped inside the silencing chamber 5, and a silencing porous sponge 7 is arranged on the multi-layer mounting bracket 6. When the noise reaches the silencing chamber 5, the silencing porous sponge 7 absorbs the noise, and the noise bounces multiple times in the space inside the silencing chamber 5, which can increase the absorption rate of the noise by the silencing porous sponge 7.

[0038] Specifically, the multi-layer mounting bracket 6 includes a multi-layer bracket 601 located at the bottom and a sealing cover 602 located at the top, and the multi-layer bracket 601 and the sealing cover 602 are an integrated metal structure. The multi-layer bracket 601 is used to fix the sound-absorbing porous sponge 7, and the two are placed together inside the sound-absorbing chamber 5, and then the sealing cover 602 seals the sound-absorbing chamber 5 to ensure the sound-absorbing effect.

[0039] Specifically, a magnetic patch 501 is fixedly provided on the outer side of the top of the silencing chamber 5, and is magnetically connected to the sealing cover 602 through the magnetic patch 501. The magnetic effect of the magnetic patch 501 can facilitate the rapid fitting and connection of the silencing chamber 5 and the multi-layer mounting bracket 6, and when the multi-layer mounting bracket 6 is taken out, the silencing porous sponge 7 that absorbs sufficient noise can be replaced, ensuring that the noise has a stable noise absorption effect in the silencing chamber 5.

[0040] Working principle:

[0041] When the device is used for silencing, the silencing porous sponge 7 is placed on the multi-layer mounting bracket 6. At this time, the multi-layer mounting bracket 6 can bear the weight of the silencing porous sponge 7 at multiple points to prevent the silencing porous sponge 7 from collapsing, thereby ensuring the silencing effect of the silencing porous sponge 7. Then the multi-layer mounting bracket 6 is sunk into the silencing chamber 5, and the magnetism of the magnetic patch 501 is used to ensure the stable connection between the multi-layer mounting bracket 6 and the silencing chamber 5.

[0042] Before silencing, the head 103 of the silencer joint 1 is fixed at the position where the pump generates noise, and the silencer joint 1 is connected to the silencer guide pipe 2 by the docking bolt 102. When absorbing noise, the noise passes through the silencer joint 1 and enters the silencer guide pipe 2, and then bounces off the reflective slope 3 for many times, finally enters the silencer chamber 5, and is absorbed, thus completing the entire silencing process.

[0043] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
