Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ventilation ducts, in particular to an environmental protection equipment ventilation duct with a sound insulation function. Background Technique
[0002] Ventilation ducts are widely used in various fields, especially in some large shopping malls, hotels, office buildings, hospitals, mechanical equipment, etc. Traditional ventilation ducts on the market usually adopt organic or inorganic fiberglass, gypsum-based air ducts. The base material pipe is a good material resistant to low and high temperatures, and has good structural strength for various thermoplastics, thermosetting plastics, organic and inorganic fiberglass, gypsum, metals, wood products, etc. It can be made into various shapes such as round and square to meet the needs of various equipment and projects.
[0003] After retrieval, the patent with the publication number CN215060407U discloses a ventilation duct with a sound insulation function, including a duct body; a second fixing block and a first fixing block are respectively arranged on the front and rear sides of the duct body. Semi-circular fixing grooves are opened on the inner sides of the second fixing block and the first fixing block, and first fixing plates are fixedly installed at the top and bottom of the second fixing block and the first fixing block. The utility model can clamp the duct body through the first fixing block and the second fixing block. By bonding a rubber pad on the outer side of the duct body and a sound insulation pipe inside the duct body, the vibration generated during use can be reduced and the noise inside the duct body can be absorbed. By installing several groups of air guiding plates, the noise can be effectively reduced when the exhaust air speed in the duct body is high. The utility model can be prefabricated in the factory and constructed in an assembled manner, and standardized operations can be carried out. By combining the prefabrication and construction of the ventilation duct with BIM technology, the construction period can be shortened, the project quality can be improved, and the construction cost can be reduced.
[0004] The following problems exist in this technical solution:
[0005] Although the sound can be absorbed and the noise can be reduced through the sound-absorbing cotton blocks inside the duct body, when splicing two duct bodies, the two duct bodies cannot be sealed. If the air flow inside the duct body is a harmful gas, it is easy to flow out from the gap between the two duct bodies, and potential safety hazards are likely to occur. Summary of the Utility Model
[0006] The purpose of the utility model is to solve the shortcomings in the prior art that although the sound can be absorbed and the noise can be reduced through the sound-absorbing cotton blocks inside the duct body, when splicing two duct bodies, the two duct bodies cannot be sealed. If the air flow inside the duct body is a harmful gas, it is easy to flow out from the gap between the two duct bodies, and potential safety hazards are likely to occur, and to propose an environmental protection equipment ventilation duct with a sound insulation function.
[0007] To achieve the above object, the utility model adopts the following technical solutions:
[0008] An environment-friendly equipment ventilation duct with a sound insulation function, comprising a duct main body. One end of the duct main body is fixedly sleeved with a second fixing ring, and the other end of the duct main body is fixedly sleeved with a first fixing ring. Four threaded holes are opened on the first fixing ring, and four round holes are opened on the second fixing ring. Bolts are arranged in the round holes, and one end of each bolt is threadedly connected with a threaded hole.
[0009] A sealing mechanism is arranged at one end of the duct main body for sealing between two duct main bodies.
[0010] A positioning mechanism is arranged on the duct main body for positioning during the installation of two duct main bodies.
[0011] In a possible design, the sealing mechanism includes a sealing ring for sealing between two duct main bodies. One side of the sealing ring is adhered to one end of the duct main body, and the sealing ring is made of rubber.
[0012] In a possible design, the positioning mechanism includes two insertion blocks for positioning during the installation of two duct main bodies. One side of each of the two insertion blocks is welded to both sides of one end of the duct main body, and two insertion slots are opened at the other end of the duct main body. The insertion blocks are inserted into the insertion slots.
[0013] In a possible design, a sound-absorbing cotton block for sound absorption is adhered to the inner wall of the duct main body.
[0014] In a possible design, the thickness of the sound-absorbing cotton block is greater than the thickness of the duct main body.
[0015] In a possible design, a fixing block is welded to the top of the duct main body, and a mounting plate for facilitating installation is welded to the top of the fixing block. Mounting holes are opened at the four corners of the mounting plate.
[0016] In this application, the second fixing ring, the first fixing ring and the pipe body are welded. When splicing two pipe bodies, take one of the pipe bodies, align the two insertion blocks at one end of the pipe body with the slots at one end of the other pipe body, and then take four bolts in sequence. One end of the bolt passes through the round hole of the second fixing ring, and then turn the bolt to make the bolt threadedly connected with the threaded hole of the first fixing ring, so that the two pipe bodies can be fixed. Through the setting of the insertion blocks and slots, when installed with bolts, the two pipe bodies are not easy to move left and right, positioning the two pipe bodies, which is convenient for installation. During the fixing process, the two pipe bodies will squeeze the sealing ring. Through the setting of the sealing ring, the two pipe bodies can be effectively sealed. Through the set sound-absorbing cotton block (the sound-absorbing cotton block is the sound-absorbing cotton), the noise inside the pipe body can be absorbed for noise elimination. Through the set mounting plate, the pipe body can be easily installed and can be installed with bolts.
[0017] In the present utility model, for the environmentally friendly equipment ventilation pipe with a sound-absorbing function, through the sealing mechanism, during the fixing process, the two pipe bodies will squeeze the sealing ring, and through the setting of the sealing ring, the two pipe bodies can be effectively sealed;
[0018] In the present utility model, for the environmentally friendly equipment ventilation pipe with a sound-absorbing function, through the positioning mechanism, when splicing two pipe bodies, take one of the pipe bodies, align the two insertion blocks at one end of the pipe body with the slots at one end of the other pipe body. Through the setting of the insertion blocks and slots, when installed with bolts, the two pipe bodies are not easy to move left and right, positioning the two pipe bodies, which is convenient for installation;
[0019] In the present utility model, the structure is reasonable. Through the sealing mechanism, the two pipe bodies can be effectively sealed, and through the positioning mechanism, the two pipe bodies can be positioned, making the two pipe bodies not easy to move left and right, which is convenient for installation.
