Description

Technical Field

[0001] The utility model relates to the technical field of air dryers, in particular to a heat dissipation type filtering drying cylinder. Background Art

[0002] Traditional drying cylinders have certain shortcomings. Among them, the application number is 202420204666.8, which discloses a detachable filter-type drying cylinder. When the compressed gas enters from the air inlet of the connecting plate, it flows to the inner cylinder cover through the guide groove between the inner shell and the cylinder outer shell. Since the compressed gas is hot air that has just been compressed and contains moisture, when it encounters the low-temperature cylinder outer shell, water droplets will condense on the inner wall of the cylinder outer shell to dry the gas. However, the heat dissipation capacity of the cylinder outer shell is limited. In the use scenario with high ambient temperature, the effect of condensing water droplets on the cylinder outer shell is low, which reduces the service life of the drying cylinder. Therefore, a drying cylinder with good heat dissipation effect is required. Utility Model Content

[0003] In order to overcome the shortcomings of the background technology, the technical solution adopted by the utility model is: a heat-dissipating filtering drying cylinder, comprising an inner liner shell, an inner liner cover, a filter element, a cylinder outer shell, a valve body and a spring, the inner liner shell is clamped with the inner liner cover, and a filter element is provided between the inner liner shell and the inner liner cover, and the inner liner shell is sleeved with a cylinder outer shell, the cylinder outer shell is detachably connected with the valve body, the valve body is provided with an air outlet and an air inlet groove connected to the filter element, a spring is provided between the inner liner cover and the cylinder outer shell, and a heat dissipation ring sheet distributed in a straight line is provided on the outside of the cylinder outer shell.

[0004] By adopting the above technical scheme, the cylinder shell and the valve body are integrally die-casted by die-casting aluminum alloy, and 11 groups of heat dissipation ring sheets are integrally formed on the outer side of the cylinder shell, thereby increasing the outer surface area of ​​the cylinder shell. Combined with the metal characteristics of aluminum alloy heat dissipation, the heat dissipation effect of the drying cylinder is improved as a whole. When the compressed gas flows in from the air inlet groove and flows out from the air outlet groove, it is easier to condense water droplets on the inner wall of the cylinder shell, thereby reducing the working pressure of the filter element and increasing the service life of the drying cylinder.

[0005] The utility model is further configured that the filter element includes a molecular sieve, a filter element and a protective cover, a molecular sieve is arranged between the inner shell and the inner cover, and the filter element is clamped between the inner shell and the valve body through the protective cover.

[0006] By adopting the above technical solution, the molecular sieve is a water-absorbing filter element with countless small holes, which is used to absorb moisture in the air. When clean air blows through the molecular sieve in the opposite direction from the air outlet, it can take away the moisture adsorbed by the molecular sieve, so that the molecular sieve can be used repeatedly; the filter element is located at the air inlet, and the filter element has the function of adhering oil stains and has a coarse filtration effect.

[0007] The utility model is further configured that the inner shell is provided with positioning strips distributed in a circumference, the cartridge shell is sleeved on the positioning strips, and a side flow channel for connecting the filter element and the molecular sieve is formed between the positioning strips and the cartridge shell;

[0008] Furthermore, the upper and lower ends of the positioning strip extend outward to form a clamping block and a protruding tooth, the inner tank cover is clamped to the inner tank shell through the clamping block, and the filter element is clamped between the protective cover and the protruding tooth.

[0009] Furthermore, the inner and outer sides of the shield are respectively provided with opening grooves and ventilation grooves distributed in a circumference, and the shield is clamped on the protruding teeth through the opening grooves.

[0010] By adopting the above technical scheme, 12 positioning strips are integrally die-casted on the outer surface of the inner shell, and a card block and a protruding tooth are formed at both ends of each positioning strip. When the compressed air enters from the air inlet groove, it enters the filter element through the air permeable groove and is coarsely filtered, flows to the side flow channel between adjacent protruding teeth, passes through the inner shell cover and the molecular sieve and flows out from the air outlet, so that the compressed air forms an annular circulating airflow in the drying cylinder, and the overall structural design is reasonable.

[0011] The utility model is further configured such that a circumferentially distributed mounting portion is provided at the bottom of the cartridge shell, the valve body is provided with a threaded hole corresponding to the mounting portion, the cartridge shell is threadedly connected to the valve body via the mounting portion, one end of the inner shell is connected to the cartridge shell via a spring, and the other end abuts against the valve body via a protruding tooth.

[0012] By adopting the above technical solution, 8 groups of mounting parts are provided around the outer shell of the cylinder, and the valve body is threadedly connected through the mounting parts, and the inner shell is arranged between the outer shell of the cylinder and the valve body. Through the action of the elastic potential energy of the spring, the protruding teeth of the inner shell are always in contact with the valve body, thereby improving the sealing effect.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The cylinder shell and the valve body are integrally die-casted by die-casting aluminum alloy. The outer surface area of ​​the cylinder shell is increased by the heat dissipation ring. Combined with the metal characteristics of aluminum alloy heat dissipation, the heat dissipation effect of the drying cylinder is improved as a whole. When the compressed gas flows in from the air inlet groove, it is easier to condense water droplets on the inner wall of the cylinder shell, reducing the working pressure of the filter element, so as to increase the service life of the drying cylinder.
