Description

Technical Field

[0001] The utility model belongs to the technical field of drying, and specifically relates to a novel drying machine. Background Art

[0002] Among the dehumidification dryers, there is a molecular sieve dryer, which uses intermittent drying. The drying function is achieved by the forward rotation of the fan, and then the regeneration function is achieved by the reverse rotation of the fan. The drying time is generally 45 minutes, and the regeneration + cooling time is 15 minutes, so the drying efficiency is 45 minutes / (45 minutes + 15 minutes) × 100% = 75%.

[0003] For the above-mentioned dryer, the core component is the fan. In order to achieve the drying and regeneration functions, the fan needs to have forward and reverse functions. Therefore, the fan is generally imported at present, but its cost is high and the delivery time is long. To solve the fan problem, you can use domestic fans as a substitute. The forward rotation capacity of domestic fans is similar to that of imported brands, but its reverse rotation capacity is much worse than that of imported brands, and the air volume does not meet the design requirements. If the fan is redeveloped, the cost will be higher, reducing the economic benefits. Utility Model Content

[0004] In order to solve the above problems in the prior art, the utility model provides a novel dryer in which the fan only needs to keep rotating forward and does not need to rotate reversely.

The first switching valve and the second switching valve are both three-way valves. The first switching valve has an air inlet port, and the second switching valve has an air outlet port, so that a drying cycle is formed among the exhaust port of the drying barrel, the first switching valve, the fan, the regeneration heating pipe, the dehumidification barrel, the second switching valve, the drying heating pipe, and the air inlet of the drying barrel, and a regeneration cycle is formed among the air inlet port of the first switching valve, the fan, the regeneration heating pipe, the dehumidification barrel, and the air outlet port of the second switching valve. In the drying cycle and the regeneration cycle, the fan is a forward-rotating fan.

[0006] Preferably, the first end of the first switching valve is an air inlet port, the second end of the first switching valve is connected to the air inlet of the drying cylinder, the third end of the first switching valve is connected to the air inlet end of the fan, the first end of the second switching valve is an air outlet port, the second end of the second switching valve is connected to the drying heating pipe, and the third end of the second switching valve is connected to the dehumidification cylinder.

[0011] Preferably, the first switching valve and the second switching valve are controlled by a common solenoid valve.

[0013] The beneficial effect of the new dryer of the utility model is that regeneration and drying are achieved by switching the first switching valve and the second switching valve, and the fan always keeps forward rotation and does not need to be reversed; and during regeneration, the fan always rotates forward, the air volume value is large, and the regeneration work can be completed more quickly, saving regeneration time, thereby improving the drying efficiency; theoretically, the regeneration + cooling time is 12 minutes, the drying time is 48 minutes, and the drying efficiency can reach 48 minutes / (48 minutes+12 minutes)×100%=80%. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments.

[0016] like Figure 1The figure shows an embodiment of the novel dryer provided by the utility model. The novel dryer comprises a drying barrel 1, a fan 6, a regeneration heating pipe 7, a dehumidification barrel 8, a drying heating pipe 10, a first switching valve 5, and a second switching valve 9. The exhaust port of the drying barrel 1 is connected to the air inlet of the drying barrel 1 through the first switching valve 5, the fan 6, the regeneration heating pipe 7, the dehumidification barrel 8, the second switching valve 9, and the drying heating pipe 10 in sequence. The dryer of the utility model is particularly suitable for a molecular sieve dryer.

[0017] The first switching valve 5 and the second switching valve 9 are both three-way valves, the first switching valve 5 has an air inlet port 13, and the second switching valve 9 has an air outlet port 14, so that a drying cycle is formed between the exhaust port of the drying barrel 1, the first switching valve 5, the fan 6, the regeneration heating tube 7, the dehumidification tube 8, the second switching valve 9, the drying heating tube 10, and the air inlet of the drying barrel 1, and a regeneration cycle is formed between the air inlet port 13 of the first switching valve 5, the fan 6, the regeneration heating tube 7, the dehumidification tube 8, and the air outlet port 14 of the second switching valve 9. In the drying cycle and the regeneration cycle, the fan 6 is a forward-rotating fan, that is, the fan always keeps rotating forward without the need for reversal.

[0018] For the dryer of the utility model, domestic fans can be used to meet the requirements and reduce the fan cost. The forward rotation capacity of domestic fans is equivalent to that of imported brands, and because the reverse air volume of imported brands is about 60% of the forward air volume, the fan always keeps forward rotation, so that the actual air volume value during regeneration is greater than the air volume value during regeneration of imported brand fans, which can complete the regeneration work more quickly, save regeneration time, and thus improve the drying efficiency.

[0019] The first end of the first switching valve 5 is an air inlet port 13, the second end of the first switching valve 5 is connected to the air inlet of the drying cylinder 1, the third end of the first switching valve 5 is connected to the air inlet end of the fan 6, the first end of the second switching valve 9 is an air outlet port 14, the second end of the second switching valve 9 is connected to the drying heating tube 10, and the third end of the second switching valve 9 is connected to the dehumidification cylinder 8.

[0020] The first switching valve and the second switching valve are three-way switching valves, and the switching of the valve bodies can be realized by sharing a solenoid valve control to perform regeneration and drying. Specifically, when drying, the first switching valve is switched to connect the second end of the first switching valve 5 with the third end of the first switching valve 5, and at the same time, the second switching valve is switched to connect the second end of the second switching valve 9 with the third end of the second switching valve 9 to form a drying passage; when regenerating, the first switching valve is switched to connect the first end of the first switching valve 5 with the third end of the first switching valve 5, and at the same time, the second switching valve is switched to connect the first end of the second switching valve 9 with the third end of the second switching valve 9 to form a regeneration passage. The regeneration and drying functions can be realized only by switching the two switching valves without adjusting the rotation direction of the fan.

[0021] The exhaust port of the drying cylinder 1 is connected to the second end of the first switching valve 5 through the drying filter 2. A condenser 3 is arranged between the drying filter 2 and the second end of the first switching valve 5. Specifically, the exhaust port of the drying cylinder 1, the drying filter 2, the condenser 3, the first switching valve 5, the fan 6, the regeneration heating pipe 7, the dehumidification cylinder 8, the second switching valve 9, the drying heating pipe 10, and the air inlet of the drying cylinder 1 are circulated in sequence to form a drying cycle.

[0022] like Figure 1 As shown, a regeneration filter 4 is provided at the air inlet port 13 of the first switching valve 5. Specifically, ambient air is discharged from the regeneration filter 4 to the outside atmosphere through the air inlet port 13 of the first switching valve 5, the fan 6, the regeneration heating pipe 7, the dehumidification cylinder 8, and the air outlet port of the second switching valve 9, forming a regeneration cycle.

[0023] like Figure 1 As shown, a first temperature probe 11 is arranged at the air outlet of the drying heating tube 10 , and a second temperature probe 12 is arranged at the air outlet of the regeneration heating tube 7 .

[0024] The beneficial effect of the new dryer of the utility model is that regeneration and drying are achieved by switching the first switching valve and the second switching valve, and the fan always keeps forward rotation and does not need to be reversed; and during regeneration, the fan always rotates forward, the air volume value is large, and the regeneration work can be completed more quickly, saving regeneration time, thereby improving the drying efficiency; theoretically, the regeneration + cooling time is 12 minutes, the drying time is 48 minutes, and the drying efficiency can reach 48 minutes / (48 minutes+12 minutes)×100%=80%.

[0025] In this specification, the utility model has been described with reference to its specific embodiments. However, it is obvious that various modifications and changes can be made without departing from the spirit and scope of the utility model. Therefore, the description and drawings should be regarded as illustrative rather than restrictive.
