Description

Technical Field

[0001] The utility model relates to auxiliary equipment for a zero-gas-consumption variable-frequency air-blast heat-absorption dryer, in particular to a silencer for a zero-gas-consumption variable-frequency air-blast heat-absorption dryer. Background Art

[0002] The existing zero-gas consumption air-blast heat desiccant generally comprises an adsorption tower and a regeneration tower. During use, the adsorption tower and the regeneration tower perform adsorption and regeneration operations alternately, thereby effectively maintaining the normal operation of the equipment for a long time.

[0003] During the regeneration process of the adsorption tower or the regeneration tower, the adsorbent in the adsorption tower or the regeneration tower needs to be heated and regenerated and blown cold and regenerated. In this process, continuous exhaust operation needs to be formed, which leads to obvious exhaust noise in the operation of the equipment. Regarding the exhaust noise, the existing practice is to install a muffler directly on the pressure relief exhaust pipe end of the adsorption tower and the regeneration tower to achieve the effect of noise reduction. Although the exhaust noise generated during the heating regeneration and blowing cold regeneration processes can be reduced to a certain extent through the setting of the muffler, due to the limited installation space of the equipment, the specifications of the muffler used are generally not too large, resulting in a relatively effective noise reduction effect, resulting in the equipment still having relatively obvious noise during actual use and operation.

[0004] Therefore, the research purpose of the present invention is to design a zero-gas-consumption variable-frequency blower heat dehumidifier silencer that can effectively and significantly improve the noise reduction effect without excessively increasing the installation space occupied. Summary of the invention

[0005] In view of the technical problems existing in the above-mentioned prior art, the utility model provides a silencer for a zero-gas-consumption variable-frequency air-blast heat absorption dryer, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the utility model is:

[0007] A silencer for a zero-gas-consumption variable-frequency air-blast heat absorption dryer, comprising:

[0008] A group of silencers are respectively connected to the gas outlet ends of the pressure relief exhaust pipes of the corresponding adsorption tower and regeneration tower, and the gas outlet ends of the silencers of the group are arranged opposite to each other;

[0009] A reinforced silencer is fixedly arranged between the air outlet ends of a group of the silencers, and corresponding electromagnets are respectively fixedly connected to the two ends of the reinforced silencer;

[0010] The connecting mechanism includes a length-adjustable pipe fitting connected to one side of the air outlet end of the muffler, and the end of the length-adjustable pipe fitting not connected to the muffler is fixedly installed with an iron connecting piece with an air guide hole in the middle. When the electromagnet is energized, the iron connecting piece is adsorbed, and the length-adjustable pipe fitting is connected to one end of the reinforced muffler.

[0011] The length-adjustable pipe fitting is an elastic metal bellows.

[0012] The iron connecting piece is arranged in a ring shape.

[0013] The side of the iron connector that is not connected to the length-adjustable pipe is fixedly bonded with a corresponding sealing gasket.

[0014] The muffler comprises a first muffler shell which is arranged in a tubular shape. The first muffler shell is divided into a plurality of muffler zones by a plurality of spaced-apart isolation sheets, and corresponding exhaust holes are respectively arranged in the middle of the isolation sheets.

[0015] The isolation sheets are respectively arranged in an arc shape.

[0016] The reinforced silencer comprises a second silencer shell in a tubular shape, the inner side of the second silencer shell is sandwiched with corresponding spacers, a plurality of corresponding sound-permeable holes are evenly arranged on the spacers, and a corresponding sound-absorbing material layer is fixedly sandwiched between the spacers and the second silencer shell.

[0017] Corresponding pressure relief exhaust valves are fixedly installed on the pressure relief exhaust pipe on one side of the air inlet end of the muffler.

[0018] Advantages of the utility model:

[0019] 1) A reinforced silencer is added between the air outlet ends of the existing silencers of the utility model, and an electromagnet and a connection mechanism are added in cooperation. During use, the electromagnet corresponding to the silencer in the exhaust state is energized to adsorb the corresponding iron connection piece, so that the corresponding length-adjustable pipe is connected to one end of the reinforced silencer, so that the two silencers can be connected with the reinforced silencer as needed, so that the two silencers can be used in coordination with the two silencers under the intervention of one reinforced silencer, thereby achieving a better silencing effect under the conditions of low cost and low space occupation.

[0020] 2) The iron connector of the utility model is not connected to the side of the length-adjustable pipe fitting and is fixedly bonded with a corresponding sealing gasket to ensure the airtightness of the connection between the electromagnet and the iron connector after the electromagnetic adsorption connection is in place, thereby ensuring the practical effect of the utility model.

[0021] 3) In the process of noise reduction of the utility model, firstly, through the intervention of the silencer, the sound is gradually passed through each silencer area during the propagation process, thereby generating reflection and interference of sound energy to form a preliminary silencer effect; then, by strengthening the intervention of the silencer, the sound after the preliminary silencer is absorbed by the sound-absorbing material layer to form a secondary silencer effect, thereby further effectively ensuring the silencer effect of the utility model.

[0032] The utility model adds a reinforced muffler 5 between the air outlet ends of the existing muffler 1, and cooperates with an electromagnet 6 and a connection mechanism 7. During use, the electromagnet 5 corresponding to the muffler 1 in the exhaust state is energized to adsorb the corresponding iron connection piece 702, so that the corresponding length-adjustable pipe 701 is connected to one end of the reinforced muffler 5, so that the two mufflers can be connected with the reinforced muffler as needed, so that the two mufflers can be used in conjunction with the two mufflers under the intervention of one reinforced muffler, thereby achieving a better muffler effect under the conditions of low cost and low space occupation.
