[0002] Air dryer is a mechanical device. Its working principle is to vaporize the moisture (mainly water or other volatile liquid components) in the material by heating, so as to obtain solid materials with specified moisture content. Air dryers are mainly divided into two categories: adsorption type and refrigeration type. Existing air dryers still have defects and deficiencies in some aspects that need to be improved:

[0003] For example, the energy-saving adsorption drying tower for compressed air purification disclosed in the publication number CN110665341A includes a tower body with a hollow structure, the tower body has an air inlet and an air outlet, the tower body is connected to a regeneration gas inlet pipe, and is characterized in that a heating cylinder is provided inside the tower body, the regeneration gas inlet pipe penetrates into the tower body and is connected to the heating cylinder, the tower body is provided with a heating element, and the heating element is at least partially located inside the heating cylinder. The present invention effectively reduces heat loss during the heating process by means of built-in heating, helps to reduce the length of the regeneration stage, improves the drying efficiency of the equipment, and has the advantages of high space utilization, compact structure, and convenient maintenance.

[0004] The existing air dryer has a weak pressure resistance. When air continues to enter the dryer, the pressure inside the dryer increases. When the pressure inside the dryer is too high, the dryer may rupture.

[0005] The existing air dryer has poor sealing performance. When air is input into the air dryer, the gas may overflow through the joint between the air pipe and the dryer body, which has certain limitations.

[0006] So we proposed a low dew point combined compressed air dryer to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to provide a low dew point combined compressed air dryer to solve the problem proposed in the above-mentioned background technology that when the internal pressure of the dryer body is too high, the dryer body may be broken and when the air is input into the air dryer, the gas may overflow to the outside through the joint between the air supply pipe and the dryer body.

[0008] To achieve the above object, the utility model provides the following technical solution: a low dew point combined compressed air dryer, comprising a dryer body, an upper end of the dryer body is penetrated and connected with an air supply pipe, and the other end of the air supply pipe is penetrated and connected with a high-efficiency separator, and the other side of the high-efficiency separator is penetrated and arranged with an evaporator, and the lower side of the evaporator is penetrated and arranged with a precooler;

[0009] Fixed side plates, the outer side of the upper end of the dryer body and the outer side of the air pipe are fixedly connected with fixed side plates, and the outer side of the top end of the dryer body is fixedly connected with an auxiliary plate, and the auxiliary plate is provided with a limiting mechanism that can clamp the two sets of fixed side plates;

[0010] The reinforcement rod is fixedly connected to the dryer body and can improve the compression resistance of the dryer body.

[0011] Furthermore, the limiting mechanism includes a threaded rod, the threaded rod is rotatably connected to the auxiliary plate, and the outer side of the threaded rod is threadedly connected to a fixed clamping plate, and the side of the fixed clamping plate is fixedly connected to an elastic clamping plate;

[0012] The fixing clamping plate is nested with a limiting rod, and the other end of the limiting rod is fixedly connected to the inner side of the auxiliary plate.

[0013] Furthermore, the fixed clamping plate forms a sliding structure through a threaded rod and a limiting rod, and the limiting rod is arranged in a "C" shape when viewed from the front, and two groups of the elastic clamping plates are arranged vertically symmetrically about the center point of the fixed clamping plate.

[0014] Furthermore, the fixed clamping plate and the fixed side plate are located at the same horizontal position, and two groups of fixed clamping plates are symmetrically arranged about the center point of the dryer body, and the inner side of the elastic clamping plate is in contact with the outer side of the fixed side plate.

[0015] Furthermore, a reinforcement ring is fixedly connected to the reinforcement rod, and a reinforcement elastic support plate is fixedly connected between the reinforcement rings.

[0016] Furthermore, the reinforcement rings are arranged in multiple groups at equal distances on the reinforcement rods, and the reinforcement elastic support plate is zigzag arranged between two groups of reinforcement rods.

[0017] Furthermore, the length of the reinforcement rod is equal to the vertical length of the dryer body.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. Compressed air saturated with water vapor enters the precooler of the dryer body. In the precooler, the incoming hot air is first cooled down by the outgoing cold air, which reduces the load of the refrigeration system. The precooled air then enters the evaporator, where the heat released by the air is absorbed by the refrigerant and cooled to a preset temperature. After the air is cooled, the excess water vapor condenses into droplets and is separated from the air through a high-efficiency separator and discharged out of the machine through the drain port. After leaving the high-efficiency separator, the cold air enters the adsorption dryer body through the air pipe for further drying.

[0020] 2. After switching by the inlet switching valve, the air is dried in one dryer body, then enters the shell side of the precooler, exchanges heat with the inlet hot air, and is heated to a certain temperature before being output. At the same time, the adsorbent in the other dryer body is dried and regenerated by a small amount of regeneration gas, which is discharged from the muffler through the exhaust valve. The double towers are switched and recycled;

[0021] 3. The user can rotate the threaded rod and drive the fixed clamping plate to move horizontally through the threaded rod. At this time, the fixed clamping plate will move to the outside of the fixed side plate. At this time, the elastic clamping plate is squeezed. The elastic clamping plate squeezes the two fixed side plates under the drive of its own elastic force, thereby improving the stability of the connection between the dryer body and the gas pipe and reducing gas leakage;

[0022] 4. During the movement of the fixed splint, it will move synchronously along the limit rod. At this time, the limit rod will limit the fixed splint, making the movement of the fixed splint more stable;

[0023] 5. The reinforcement rod is arranged on the dryer body, and the strength of the dryer body shell itself is strengthened by the reinforcement rod. At the same time, a plurality of groups of reinforcement elastic support plates are arranged on the reinforcement rod. Under the elastic force of the reinforcement elastic support plates, the air pressure inside the dryer body can be further buffered, thereby improving the pressure resistance of the dryer body.
