Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of automobile mechanical equipment, concretely relates to a drying tank with prolonged drying effect and an air compressor. BACKGROUND

[0002] Drying tank is an indispensable safety filter system for air compressor, and its volume is usually made very small due to the limitation of installation space on the vehicle, and it is generally designed as Y-shaped or I-shaped layout design. At present, there are also external drying tanks installed to prolong the overall volume and adsorption length of the drying tank, but the industry trend is increasingly inclined to single drying tank design with stable drying function. At the same time, the drying tank is generally placed at the rear end of the air compressor, and the pressure is large. For the drying tank used for a long time, the drying agent will inevitably have a dusting problem. Since the dusting particles are very small, the use of high-precision filter sheets will inevitably cause large flow resistance, thereby causing low-efficiency work and high energy consumption of the air compressor.

[0003] The utility model provides a drying tank with prolonged adsorption effect, which prolongs the contact time of wet air and drying agent by changing the distribution and route of air flow under the condition of constant total mass, thereby achieving the effect of prolonging adsorption. By changing the installation position, the dusting problem caused by high pressure and the large flow resistance hazard can be avoided, thereby preventing the blockage of the air suspension system pipeline after long-term use in the future. UTILITY MODEL CONTENTS

[0004] The utility model discloses a drying tank with prolonged drying effect and an air compressor, which can solve the problems of unsatisfactory drying effect of the drying tank and dusting of the drying agent in the drying tank, which causes low-efficiency work and high energy consumption of the air compressor. The utility model realizes the effect of prolonging adsorption by changing the distribution and route of air flow in the drying tank under the condition of constant total mass of the drying tank, thereby prolonging the contact time of air and drying agent. The drying tank is installed at the front end of the air compressor, which avoids the dusting problem of the drying agent caused by high pressure and the large flow resistance hazard, thereby preventing the blockage of the air suspension system pipeline after long-term use in the future.

[0006] The utility model discloses a drying tank with prolonged drying effect and an air compressor, which can solve the problems of unsatisfactory drying effect of the drying tank and dusting of the drying agent in the drying tank, which causes low-efficiency work and high energy consumption of the air compressor. The utility model realizes the effect of prolonging adsorption by changing the distribution and route of air flow in the drying tank under the condition of constant total mass of the drying tank, thereby prolonging the contact time of air and drying agent. The drying tank is installed at the front end of the air compressor, which avoids the dusting problem of the drying agent caused by high pressure and the large flow resistance hazard, thereby preventing the blockage of the air suspension system pipeline after long-term use in the future.

[0007] The air inlet of the drying tank is located in the first chamber, the air outlet is located in the tail end chamber, and the air flow path in the drying tank is Z-shaped.

[0008] Further, the drying tank is formed by splicing a plurality of tank bodies together, and air flow passages are arranged between the tank bodies.

[0009] Further, the air inlet is arranged at the upper end of the first chamber, and the air outlet is arranged at the bottom of the tail end chamber.

[0010] Further, the two air flow passages of the chamber are arranged at the upper end of one side and the lower end of the other side of the chamber.

[0011] Further, the number of the chambers is greater than or equal to 2.

[0012] Further, the drying agent includes any one of activated alumina drying agent, silica gel drying agent, molecular sieve drying agent, and activated carbon drying agent.

[0013] Further, the particle size of the drying agent is 2-5 mm.

[0014] Further, the air inlet of the drying tank is provided with a dustproof filter screen, and the pore size of the dustproof filter screen is 20-60 μm. The dustproof filter screen is arranged at the air inlet of the drying tank. Since the drying tank is arranged at the front end of the air compressor, a large amount of air will first enter the drying tank after the air compressor is started. The dustproof filter screen arranged at the air inlet of the drying tank is used to filter the dust or impurities in the air, so as to prevent the dust and impurities from entering the drying tank, the drying agent from being dirty, and the drying effect from being affected. If the dust and impurities adhere to the inner wall of the drying tank, it is also not conducive to the replacement of the drying agent.

[0015] Further, the drying agent in the chamber is arranged between two air permeable plates, the air permeable plates are provided with air outlets, and the pore size of the air outlets is smaller than the particle size of the drying agent. The air permeable plates arranged at the lower end of the drying agent are used to prevent the drying agent particles from falling out and affect the drying effect. At the same time, the air permeable plates also have a certain filtering effect on the dusting of the drying agent.

[0016] Further, the pore size of the air outlet on the air permeable plate is 0.2-1 mm.

[0017] Further, the air permeable plate is fixed to the inner side of the drying tank by means of bonding, buckling connection or screw connection.

[0018] Further, the position of the air permeable plate is lower than the air flow passage at the upper end of the drying tank and higher than the air flow passage at the lower end.

[0019] Further, the material of the drying tank is any one of PA6, PP and PC. The above transparent or translucent plastic is used to manufacture the drying tank, which has low cost, and the transparent or translucent drying tank manufactured has the advantage of facilitating the observation of the use of the internal drying agent.

[0020] Furthermore, the dimensions of the drying tank are: length 90~110mm, width 60~80mm, and height 90~110mm.

[0021] Furthermore, the drying jar weighs 250~350g.

[0022] The second technical solution of this utility model is to provide an air compressor, wherein the drying tank with the extended drying effect is installed at the front end of the air compressor, the air outlet of the drying tank is connected to the air compressor, and the inside of the drying tank is a negative pressure zone when the air compressor is running.

[0023] The drying canister is placed at the front end of the air supply. After the air compressor starts working, it will draw a semi-vacuum into the drying canister to form a negative pressure zone. At this time, due to the pressure difference between the inside and outside, the air inlet of the drying canister will continuously force the outside air into the drying canister. After passing through the drying canister, the path is designed in a Z shape, which increases the path of the humid air and can fully increase its adsorption time. Then the dried gas is discharged from the outlet to the air compressor.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. This utility model sets up a drying canister as multiple chambers connected by air vents, with each chamber's air vent located at the top or bottom of the chamber. Without increasing the volume of the drying canister or the mass of the desiccant, by changing the airflow path in the drying canister from the traditional Y or I shape to a Z shape, the path distance is increased by more than 2 times, allowing the outside air to react and adsorb with the desiccant for a longer period, thus achieving a more complete adsorption effect.

[0026] 2. This utility model installs the drying tank at the front end of the air compressor. The negative pressure generated by the continuous intake of air at the front end of the air compressor causes the air to be passively drawn into the drying tank and then enter the air compressor after flowing in the drying tank. This avoids the hidden danger of large flow resistance caused by too many Z-shaped bends.

[0027] 3. This utility model has a dust filter screen installed at the air inlet of the drying tank to prevent dust in the air drawn in by negative pressure from entering the drying tank. A vent plate is installed above and below the desiccant in the drying tank, and multiple air outlet holes are provided on the vent plate to prevent the desiccant from falling out and to prevent the potential blockage of the air suspension system pipeline caused by the desiccant dusting.

[0028] 4. By installing the drying tank at the front end of the air compressor, this utility model reduces the material load on the drying tank, thus allowing the drying tank to be manufactured using cheaper materials, saving costs. Attached Figure Description
