Description

Technical Field

[0001] The utility model relates to the technical field of dryers, in particular to a high-pressure adsorption dryer. Background Art

[0002] High-pressure adsorption dryer uses advanced chemical technology. Its principle is to use the difference between the volume of water and air molecules to filter out the saturated water vapor in the compressed air by using a special molecular sieve for gas purification. The water molecules can be easily adsorbed in the molecular sieve particles, and then the molecular sieve can be restored by regeneration method. The dew point of the compressed air can easily reach -40℃. The high-pressure adsorption dryer achieves the drying effect through "pressure change" (pressure swing adsorption principle). Since the air's ability to hold water vapor is inversely proportional to the pressure, a part of the air after drying (called regeneration gas) is decompressed and expanded to atmospheric pressure. This pressure change makes the expanded air drier, and then it is allowed to flow through the desiccant layer that needs to be regenerated without air flow (that is, the drying tower that has absorbed enough water vapor). The dry regeneration gas absorbs the moisture in the desiccant and takes it out of the dryer to achieve the purpose of dehumidification. The two towers work in a cycle without heat source, and continuously provide dry compressed air to the user's gas system.

[0003] For example, the publication number CN219441172U is a high-pressure adsorption dryer, including a base, a fixed frame fixedly connected to the upper end face of the base, a first adsorption tower and a second adsorption tower symmetrically fixedly connected to the fixed frame, a first top air chamber is arranged at the top of the first adsorption tower, a second top air chamber is arranged at the top of the second adsorption tower, a first bottom air chamber is arranged at the bottom end of the first adsorption tower, a second bottom air chamber is arranged at the bottom end of the second adsorption tower, a driving motor is arranged at the lower end of the first bottom air chamber and the second bottom air chamber, an electric control box is fixedly installed between the first adsorption tower and the second adsorption tower, an electromagnetic valve group is fixedly installed below the electric control box between the first adsorption tower and the second adsorption tower, a plurality of shock absorbing mechanisms are evenly distributed on the side end face of the base, the design of the plurality of shock absorbing mechanisms can be arranged by the cooperation of shock absorbing springs and sliding rods, and at the same time, the elastic force of the springs can absorb the vibration force during the drying reaction inside the first adsorption tower and the second adsorption tower, thereby reducing the shaking damage caused by the overall structure.

[0004] However, in the prior art, conventional high-pressure adsorption dryers need to discharge unqualified gas through a muffler, and the discharged gas is high-pressure gas, which may cause damage to the muffler, thereby limiting the practicability of the device to a certain extent. Utility Model Content

[0005] The utility model aims to solve the problem that the conventional high-pressure adsorption dryer in the prior art needs to discharge unqualified gas through a muffler, and the discharged gas is high-pressure gas, which may cause damage to the muffler.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-pressure adsorption dryer, comprising a base plate and an adsorption tank, the upper surface of the adsorption tank is fixedly connected to a gas storage chamber, one side of the gas storage chamber is fixedly connected to a second connecting pipe, the end of the second connecting pipe away from the gas storage chamber is fixedly connected to an electromagnetic valve B, the upper surface of the electromagnetic valve B is fixedly connected to a muffler, the muffler has a built-in buffer assembly, the buffer assembly includes a damping spring fixedly connected to the inner top wall of the muffler, one end of the damping spring is fixedly connected to a piston, and the surface of the muffler is provided with exhaust holes that decrease from the inside to the outside.

[0007] As a preferred embodiment, the four sides of the base plate are fixedly connected with equidistantly arranged shock absorbing components, and the shock absorbing components include a fixing plate.

[0008] As a preferred embodiment, the lower surface of the fixing plate is fixedly connected to a mounting plate via a first shock-absorbing spring, and the upper surface of the mounting plate is fixedly connected to a mounting block at the axis of the first shock-absorbing spring.

[0009] As a preferred embodiment, a plurality of equally spaced second shock-absorbing springs are fixedly connected to the inner bottom wall of the mounting block, one end of the second shock-absorbing spring is fixedly connected to a slider, the upper surface of the slider is fixedly connected to a fixing rod, and the top end of the fixing rod is fixedly connected to the fixing plate.

[0010] As a preferred embodiment, support frames are symmetrically fixedly connected to the upper surface of the bottom plate, and adsorption tanks are fixedly connected to the inner sides of the two support frames.

[0011] As a preferred implementation, a motor is fixedly connected to the lower surface of the adsorption tank, and a first connecting pipe is fixedly connected to one side of the motor.

[0012] As a preferred embodiment, one end of the first connecting pipe away from the motor is fixedly connected to a solenoid valve A, and one side of the solenoid valve A is fixedly connected to an air intake pipe.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. The utility model provides a buffer component to buffer the discharged high-pressure gas and reduce the damage to the muffler. Unqualified high-pressure gas is discharged into the muffler through the solenoid valve B. The high-pressure airflow carried by the gas will impact the piston and compress the damping spring, causing the piston to gradually move up. The gas is discharged to the outside from the exhaust hole, and the sound insulation cotton and the exhaust hole itself decrease from the inside to the outside, which effectively achieves the purpose of silencing, improves the practicability of the device, and prolongs the service life of the muffler.

[0015] 2. The utility model sets a shock-absorbing component to reduce the vibration generated during the operation of the dryer. When the dryer vibrates, it will be synchronously transmitted to the fixed plate and buffered once under the action of the first shock-absorbing spring. The other part of the vibration slides in the mounting block through the fixed rod and compresses the second shock-absorbing spring for secondary buffering. The vibration generated during the operation of the dryer is reduced through double buffering, thereby improving the stability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figure 1-4 As shown, the base plate 1 is fixedly connected with equidistantly arranged shock-absorbing components on all four sides, and the shock-absorbing components include a fixed plate 15, and the lower surface of the fixed plate 15 is fixedly connected with a mounting plate 21 through a first shock-absorbing spring 16, and the upper surface of the mounting plate 21 is fixedly connected with a mounting block 20 at the axis of the first shock-absorbing spring 16. The vibration generated during the operation of the adsorption tank 3 will be synchronously transmitted to the fixed plate 15, and the first shock-absorbing spring 16 will perform a buffering and shock-absorbing on the adsorption tank 3, thereby improving the stability of the device operation.

[0025] like Figure 1-4 As shown, the inner bottom wall of the mounting block 20 is fixedly connected with a plurality of equidistantly arranged second shock absorbing springs 19, one end of the second shock absorbing spring 19 is fixedly connected with a slider 18, the upper surface of the slider 18 is fixedly connected with a fixing rod 17, and the top end of the fixing rod 17 is fixedly connected to the fixing plate 15, and the other part of the vibration slides in the mounting block 20 through the fixing rod 17 and compresses the second shock absorbing spring 19 for secondary buffering, which further improves the stability of the device and ensures the stable operation of the device.
