Description

Technical Field

[0001] The utility model relates to the technical field of plastic machinery, in particular to a molecular sieve tower drying machine structure which is high-efficiency and easy to maintain. Background Art

[0002] Traditional dryer systems are bulky and occupy a large area. The cyclone filter group is placed outside the equipment, and all components are scattered throughout the system. The maintenance cost requires multiple maintenance personnel to perform maintenance work separately, which is too high. Summary of the invention

[0003] The utility model overcomes the deficiencies of the prior art and provides a high-efficiency and easy-to-maintain molecular sieve tower dryer structure, which integrates a cyclone filter group that occupies a large area and is complex to install into the dryer, thereby greatly reducing the floor space and installation and maintenance intensity.

[0004] To achieve the above purpose, a high-efficiency and easy-to-maintain molecular sieve tower dryer structure is designed, including a mechanism frame, a mechanism bottom plate, a molecular sieve tower group, a filter group, a heat exchanger group, and a distribution valve group, characterized in that: the mechanism frame is a rectangular frame structure, and a mechanism bottom plate is provided at the bottom of the mechanism frame; a molecular sieve tower group, a filter group, a heat exchanger group, and a distribution valve group are respectively provided in the mechanism frame, a heat exchanger group is provided below the filter group, and the filter group and the heat exchanger group are connected through a filter and a heat exchanger connector, and the outlet of the heat exchanger group is connected to the distribution valve group through a distribution valve return air duct; the molecular sieve tower group is connected to one side of the distribution valve group, and the bottom of the molecular sieve tower group is fixed on the mechanism bottom plate.

[0005] The filter group is a double filter group composed of two filters, and the two filters are arranged in an upper and lower distribution.

[0006] One side of the filter group is connected to one end of the return air duct, and the other end of the return air duct passes through the mechanism frame and is located above the mechanism frame.

[0007] One side of the upper portion of the distribution valve group is connected to the air outlet of the distribution valve, and one side of the lower portion of the distribution valve group is connected to the air inlet of the distribution valve.

[0008] The molecular sieve tower group includes a left molecular sieve tower and a right molecular sieve tower. The tops of the left molecular sieve tower and the right molecular sieve tower are respectively connected to the left molecular sieve tower air outlet and the right molecular sieve tower air outlet, and the left molecular sieve tower air outlet and the right molecular sieve tower air outlet are respectively connected to the distribution valve air outlet of the distribution valve group; the bottoms of the left molecular sieve tower and the right molecular sieve tower are respectively connected to the left molecular sieve tower air inlet and the right molecular sieve tower air inlet.

[0009] The heat exchanger group is connected to the mechanism bottom plate through a heat exchanger bracket.

[0010] Compared with the prior art, the utility model provides a high-efficiency and easy-to-maintain molecular sieve tower dryer structure, which integrates a cyclone filter group that occupies a large area and is complicated to install into the dryer, greatly reducing the occupied area and the installation and maintenance intensity.

[0011] The utility model installs the heaviest molecular sieve tower group on the bottom plate of the mechanism, which reduces the height for easy maintenance, reduces the risk of operators, and makes the entire structure more stable. In view of the stability of the structure, the volume of the molecular sieve tower is increased, so that the capacity of the molecular sieve is increased from the original 290kg to 452kg. In addition, this design improves the following data compared with the old version: the filtration area is increased by 47%; the cooling capacity is increased by 45%; the life of the molecular sieve is increased by 40%; it is easier to maintain and the maintenance time is reduced by 50%.

DETAILED DESCRIPTION

[0020] The utility model is further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 7As shown, the mechanism frame 15 is a rectangular frame structure, and a mechanism base plate 3 is provided at the bottom of the mechanism frame 15; a molecular sieve tower group, a filter group 10, a heat exchanger group 8, and a distribution valve group 13 are respectively provided in the mechanism frame 15, and a heat exchanger group 8 is provided below the filter group 10, and the filter group 10 and the heat exchanger group 8 are connected through a filter and a heat exchanger connector 9, and the outlet of the heat exchanger group 8 is connected to the distribution valve group 13 through a distribution valve return air pipe 5; a molecular sieve tower group is connected to one side of the distribution valve group 13, and the bottom of the molecular sieve tower group is fixed on the mechanism base plate 3.

[0022] The filter group 10 is a double filter group composed of two filters, and the two filters are arranged in an upper and lower distribution.

[0023] One side of the filter group 10 is connected to one end of the return air duct 11 , and the other end of the return air duct 11 passes through the mechanism frame 15 and is located above the mechanism frame 15 .

[0024] One side of the upper portion of the distribution valve group 13 is connected to the distribution valve air outlet 7 , and one side of the lower portion of the distribution valve group 13 is connected to the distribution valve air inlet 6 .

[0025] The molecular sieve tower group includes a left molecular sieve tower 2 and a right molecular sieve tower 1. The tops of the left molecular sieve tower 2 and the right molecular sieve tower 1 are respectively connected to the left molecular sieve tower air outlet 2A and the right molecular sieve tower air outlet 1A, and the left molecular sieve tower air outlet 2A and the right molecular sieve tower air outlet 1A are respectively connected to the distribution valve air outlet 7 of the distribution valve group 13; the bottoms of the left molecular sieve tower 2 and the right molecular sieve tower 1 are respectively connected to the left molecular sieve tower air inlet 2B and the right molecular sieve tower air inlet 1B.

[0026] The heat exchanger group 8 is connected to the mechanism base plate 3 via the heat exchanger bracket 4 .

[0027] The working principle of the utility model is as follows: the air containing dust and high temperature and moisture returned from the closed loop of the drying barrel passes through the return air duct 11 and enters the filter group 10, where the dust is filtered, and the return air then passes through the filter and the heat exchanger connector 9 to enter the heat exchanger group 8, where the air temperature is cooled, and enters the distribution valve group 13 through the return air duct 5 connected to the distribution valve, where the air is distributed to the right molecular sieve tower 1 or the left molecular sieve tower 2 as needed by the distribution valve inlet 6, and is connected by the right molecular sieve tower inlet 1B and the left molecular sieve tower inlet 2B, where the moisture of the air is adsorbed by the molecular sieve and becomes dry air (dew point is lower than -40°C), and the dry air is connected to the distribution valve outlet 7 of the distribution valve group 13 through the right molecular sieve tower outlet 1A and the left molecular sieve tower outlet 2A, and the drying stage is completed.

[0028] The important part of the drying system is the molecular sieve unit. Increasing the capacity of the molecular sieve is a priority, but increasing the capacity of the molecular sieve is bound to increase the floor space and weight of the dryer. In addition, the energy utilization efficiency and the small floor space are also conflicting. In order to maximize the efficiency, the utility model breaks the conventional structural design and introduces a brand-new structural design: the cyclone filter group 17, which occupies a large area and is complex to install, is integrated into the dryer, which greatly reduces the floor space and installation and maintenance intensity; and the heaviest molecular sieve tower groups 1 and 2 are installed on the mechanism bottom plate 3, which reduces the height for easy maintenance, reduces the risk of operators, and the entire structure is more stable. In view of the stability of the structure, the volume of the molecular sieve tower is increased, so that the capacity of the molecular sieve is increased from the original 290kg to 452kg. In addition, the design improves the following data compared with the old version: the filtration area is increased by 47%; the cooling capacity is increased by 45%; the life of the molecular sieve is increased by 40%; it is easier to maintain and reduces the maintenance time by 50%.
