Abstract
The utility model relates to a direct air suction muffler. A horn-shaped opening end of a bellows is designed to be contacted with a compressor casing in matching mode. Two partition boards are arranged on an upper cavity of the muffler, an air suction pipe arranged at the upper end of the muffler extends to a lower cavity. A semispherical filter screen is welded to the lower end of the muffler. The upper cavity is welded to the lower cavity in high frequency mode by utilizing iron wires, thereby being capable of well reducing air suction noise, improving efficiency of a compressor and being especially suitable for improvement of the performance of a reciprocating compressor.
Description
Technical field
The utility model relates to a kind of direct air suction silencer, is applicable to reciprocating type refrigeration compressor.
Background technique
As everyone knows, in traditional reciprocating type refrigeration compressor, compressor is through sucking low-temperature low-pressure refrigerant gas; Discharge high temperature and high pressure gas, reach the function of refrigeration through heat-exchange system, refrigeration compressor adopts half direct air suction silencer usually; The distance of the suction tude on this baffler intakeport and the housing still leaves certain distance; Therefore, after the gas that the air inlet mouth of pipe from housing sucks was inhaled into enclosure interior, some gas directly was inhaled in the air-breathing silencing cavity.Still some gas is diffused rapidly to the housing inner chamber in addition; Gas that is spread and housing and mechanical parts, motor, refrigeration oil carries out heat exchange fast, just is inhaled into then in the air-breathing silencing cavity; This part gas is after exchanging with endoceliac gas of shell and part; The temperature of gas is raise, and the mass flow rate of working medium reduces, and the refrigerating efficiency that has directly influenced compressor is the COP value.
Summary of the invention
The utility model mainly is not good and cause refrigerating efficiency to reduce and the noise problems of too in order to solve in the existing technology inspiratory effects.
The utility model solves the technological scheme that its technical problem adopted: a kind of direct air suction silencer; Comprise baffler epicoele and baffler cavity of resorption; It is characterized in that: the horn shape bellows coincide with compressor housing and contacts; The baffler epicoele is provided with first dividing plate and second partition, and the straight tube that stretches into of baffler epicoele is provided with hemisphere stainless steel filter screen.
The utility model installs a horn shape bellows that coincide and contact with compressor housing additional at baffler cavity of resorption sucking pipe afterbody; Guaranteeing to suck refrigerant is not heated; Realize aiming at the air-breathing mouth of pipe and suck low-temperature refrigerant steam, reduce compressor noise simultaneously to improve compressor efficiency; The baffler epicoele is provided with two dividing plates, can carry out acoustic reflection, refraction to refrigerant, utilizes the pipeline section that stretches between pipe and suction tude to change to reach mutual interference the between sound wave simultaneously and eliminates the part low frequency noise.
At the air suction silencer cavity of resorption compensation air suction structure being set helps remedying air-breathing.
Air suction silencer epicoele and air suction silencer cavity of resorption docking groove interdigitating section are placed iron wire, adopt high-frequency welding manner to connect, and can strengthen the sealability of this baffler, further reduce noise.
The utility model adopts heat to melt the sealability that welding has strengthened this baffler in the upper and lower chamber of air suction silencer; Reduce noise, the compensation air suction structure can remedy air-breathing, and the shape and structure of bellows and housing coincide and design; Guarantee to suck refrigerant and be not heated, improve overall efficiency.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
In the accompanying drawing: 1-baffler epicoele, the 2-iron wire, the 3-filter screen, 4-baffler cavity of resorption, 5-first dividing plate, the 6-second partition, 7-stretches into straight tube, 8-horn shape bellows, the 9-fixing clamp, 10-compensates air suction structure, 11-compressor housing, 12-movement.
Be provided with first dividing plate 5 and second partition 6 in the baffler epicoele 1, can carry out acoustic reflection, refraction to refrigerant through these two dividing plates and utilize the pipeline section variation of stretching between straight tube 7 and suction tude (being that caliber changes) to eliminate the part low frequency noise simultaneously to reach to interfere each other between sound wave; Epicoele stretches into soldering stainless steel hemisphere filter screen 3 on the pipe 7, and baffler cavity of resorption 4 is provided with compensation air suction structure 10, and iron wire 2 high frequency weldings are adopted in upper and lower chamber, and sealing firmly; Loudspeaker bellows 8 adopts fixing clamp 9 to be fixedly clamped with baffler cavity of resorption 4 tail pipes; Directly air suction silencer and 12 butt joints of compressor movement; Aim at the air-breathing mouth of pipe; And coincide with compressor housing 11 and contacts, realize sucking low-temperature refrigerant steam with the raising compressor efficiency, reduce compressor noise simultaneously.
