Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, and more specifically to a winter start-up preheating device for air compressors. Background Art

[0002] The existing cooling device of the Atlas air compressor does not cool comprehensively enough and cannot be used for all-round cooling, so the efficiency is low; and the existing cooling device of the Atlas air compressor has a single cooling method, and the efficiency improvement is not obvious enough; the cooling device of the existing Atlas air compressor has a relatively complex structure, and subsequent cleaning is relatively troublesome.

[0003] In view of the above problems, regarding the technical problem of low efficiency of the cooling device of the existing air compressor, after a lot of searching, the patent number CN214092233U was found to be a cooling device for an Atlas air compressor for fine denier processing, including a cooling box, a circulation box, a condensing box, a water inlet, a water outlet and an air cooling box. The top of the cooling box is fixedly installed with a circulation box, the inside of the circulation box is fixedly installed with a guide fan, the side of the guide fan is fixedly installed with a sixth water pipe, the side of the sixth water pipe is fixedly installed with a condensing box, the inside of the condensing box is fixedly installed with a condensing chamber, the inside of the condensing chamber is evenly distributed with transverse fins, the other side of the condensing box is fixedly installed with a first water pipe, the other end of the first water pipe is fixedly installed with a return device, and the other side of the heat sink is fixedly installed with a heat dissipation fan. The utility model ensures its use experience by circulating the liquid through the guide fan during use, and after cooling through the transverse fins inside the condensing box, it flows back into the cooling box for cooling, thereby ensuring its use experience.

[0004] However, when the ambient temperature is too low in winter, the cooling water temperature of the air compressor is too low, and the air compressor unit itself has no lubricating oil preheating device. After the air compressor is started, the oil temperature is too low, and under the cooling of the cooler, the oil temperature is difficult to rise. The lubricating oil is viscous, causing the air compressor lubricating oil pressure to be low and the unit protection to be activated, making it impossible to start and run normally.

[0005] The utility model can control the water flow rate and adjust the water flow direction according to the water temperature. Utility Model Content

[0006] The utility model aims to solve the technical problems raised by the above-mentioned background technology and provides a winter startup preheating device for an air compressor, which can achieve the effect of controlling the water flow rate and adjusting the water flow direction according to the water temperature.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a winter start-up preheating device for an air compressor, comprising: a cooling box, an oil inlet is installed at the top of the right end of the cooling box, a water outlet pipe is installed at the bottom of the oil inlet, an air inlet is installed at the bottom of the water outlet pipe, a water pump is installed at the other end of the water outlet pipe, the water pump input end is connected to the water outlet pipe, the water pump output end is connected to a regulator, a first water branch pipe is installed at the top of the regulator, a second water branch pipe is installed at the bottom of the regulator, a heat sink is installed at the other end of the first water branch pipe, the heat sink output end is connected to the water inlet pipe, and the other end of the second water branch pipe is connected to the water inlet pipe.

[0008] A further preferred solution is that a plurality of heat dissipation fins are arranged inside the heat dissipation box.

[0009] A further preferred solution: a throttle valve is installed on the water outlet pipe.

[0010] A further preferred solution is that the diameter of the first water distribution pipe is half of the diameter of the second water distribution pipe.

[0011] A further preferred solution: the regulator includes: a fixed block, a spring, a movable block, a sealing block, an ejector pin, an expansion body, a protective sleeve and an outer shell. The output end of the water pump is connected to the outer shell, the center of the outer shell is connected to the fixed block, a spring is installed in the center of the fixed block, a movable block is installed on the top of the spring, an expansion body is arranged inside the movable block, an ejector pin is installed in the center of the expansion body, a protective sleeve is installed on the outside of the ejector pin, and a sealing block is installed on the top of the movable block.

[0012] A further preferred embodiment: the expansion body is made of paraffin.

[0013] A further preferred solution is that the movable block fits with the second water distribution pipe.

[0014] Beneficial effects:

[0015] 1. By setting a throttle valve, the effect of controlling the water flow rate can be achieved. When the air compressor is first started in winter, the cooling water flow rate of the cooler is adjusted through the throttle valve to reduce the flow rate and reduce the cooling efficiency of the cooler. The high temperature generated by the start-up of the air compressor quickly increases the lubricating oil temperature through heat transfer through the machine body, and the oil pressure reaches the range of the unit process requirements. When the oil temperature reaches the unit process requirements, the throttle valve is fully opened to increase the water flow rate and maximize the cooling efficiency of the cooler, thereby meeting the needs of the machine. The throttle valve is used to avoid taking temporary measures such as steam heating, electric heating, etc. that are time-consuming, labor-intensive and inefficient preheating;

[0016] 2. The regulator is provided to adjust the water flow direction according to the water temperature. When the water temperature rises, the expansion body melts and expands due to the heat. Since the sealing fastener is provided to restrict the expansion body inside the movable block, the expansion body will squeeze out the ejector pin at this time. Since the top of the ejector pin is fixed on the fixed block, the ejector pin will push the movable block downward, so that the top of the movable block leaves the fixed block. The water can flow from the top of the movable block to the first water distribution pipe. When the water temperature continues to rise, the movable block will eventually block the second water distribution pipe. At this time, the water can only flow out from the first water distribution pipe.

[0017] 3. In summary, this type of air compressor winter start-up preheating device, by providing structures such as a throttle valve and a regulator, can control the water flow rate and adjust the water flow direction according to the water temperature, so that the lubricating oil can generate high temperature through the operation of the air compressor to quickly increase the lubricating oil temperature, thereby ensuring the normal operation of the air compressor.

DETAILED DESCRIPTION

[0023] The following will be combined with the attached embodiment of the utility model Figure 1-Figure 4 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0024] See also Figure 1-4In the embodiment of the utility model, a winter start-up preheating device for an air compressor includes: a cooling box 1, an oil inlet 5 is installed at the top right end of the cooling box 1, a water outlet pipe 3 is installed at the bottom end of the oil inlet 5, an air inlet 2 is installed at the bottom end of the water outlet pipe 3, a water pump 7 is installed at the other end of the water outlet pipe 3, the input end of the water pump 7 is connected to the water outlet pipe 3, the output end of the water pump 7 is connected to a regulator 6, a first water branch pipe 8 is installed at the top end of the regulator 6, a second water branch pipe 9 is installed at the bottom end of the regulator 6, a heat sink 10 is installed at the other end of the first water branch pipe 8, the output end of the heat sink 10 is connected to a water inlet pipe 11, and the other end of the second water branch pipe 9 is connected to the water inlet pipe 11. In addition, the way in which the cooling box 1 cools water is similar to the comparative document results mentioned in the background technology, so its structure and working principle will not be described in detail.

[0025] In the embodiment of the utility model, a plurality of heat dissipation fins are arranged inside the heat dissipation box 10 to achieve the effect of accelerating heat dissipation.

[0026] In the embodiment of the utility model, a throttle valve 4 is installed on the water outlet pipe 3 to achieve the effect of adjusting the amount of water outlet.

[0027] In the embodiment of the utility model, the diameter of the first water distribution pipe 8 is half of the diameter of the second water distribution pipe 9 .

[0028] In the embodiment of the utility model, the regulator 6 includes: a fixed block 601, a spring 602, a movable block 603, a sealing block 604, a thimble 605, an expansion body 606, a protective sleeve 607 and a shell 608. The output end of the water pump 7 is connected to the shell 608, and the fixed block 601 is connected to the center of the shell 608. The spring 602 is installed in the center of the fixed block 601, and the movable block 603 is installed on the top of the spring 602. The expansion body 606 is arranged inside the movable block 603, and the thimble 605 is installed in the center of the expansion body 606. The protective sleeve 607 is installed on the outside of the thimble 605, and the sealing block 604 is installed on the top of the movable block 603. When the water temperature is low, the expansion body 606 is small in size. Under the push of the spring 602, the movable block The top of 603 is stuck in the fixed block 601. At this time, water flows out from the second water distribution pipe 9 at the bottom of the fixed block 601, and cannot flow out from the top of the fixed block 601. When the water temperature rises, the expansion body 606 melts and expands due to the heat. Since the sealing member is set, the expansion body 606 is restricted inside the movable block 603. At this time, the expansion body 606 will squeeze out the ejector pin 605. Since the top of the ejector pin 605 is fixed on the fixed block 601, the ejector pin 605 will push the movable block 603 downward, so that the top of the movable block 603 leaves the fixed block 601, and the water can flow from the top of the movable block 603 to the first water distribution pipe 8. When the water temperature continues to rise, the movable block 603 will eventually block the second water distribution pipe 9, and the water can only flow out from the first water distribution pipe 8.

[0029] In the embodiment of the utility model, the material of the expansion body 606 is paraffin, so that the expansion body 606 melts and expands when heated.

[0030] In the embodiment of the utility model, the movable block 603 is matched with the second water distribution pipe 9, so that the movable block 603 can block the second water distribution pipe 9 when moving downward.

[0031] Working principle: when in use, the water pump 7 will pump water out of the cooling box 1, and a throttle valve 4 is installed on the water outlet pipe 3. When the air compressor is initially started in winter, the cooling water flow of the cooler is adjusted through the throttle valve 4 to reduce the flow and reduce the cooling efficiency of the cooler. The high temperature generated by the start-up of the air compressor quickly increases the temperature of the lubricating oil through heat transfer in the machine body, and the oil pressure reaches the range of the unit process requirements. When the oil temperature reaches the unit process requirements, the throttle valve 4 is fully opened to increase the water flow and maximize the cooling efficiency of the cooler, thereby meeting the needs of the machine. The throttle valve 4 is used to avoid taking temporary measures such as steam heating and electric heating that are time-consuming, labor-intensive and inefficient preheating. After the water passes through the water pump 7, it is pumped into the regulator 6 by the water pump 7. When the water temperature is low, the expansion body 606 is small in size. Under the push of the spring 602, the top of the movable block 603 is stuck in the fixed block 601. At this time, the water flows out from the second water distribution pipe 9 at the bottom of the fixed block 601 and cannot flow out from the fixed block 60 1, when the water temperature rises, the expansion body 606 melts and expands due to the heat. Because the sealing block is set, the expansion body 606 is restricted inside the movable block 603. At this time, the expansion body 606 will squeeze out the ejector pin 605. Because the top of the ejector pin 605 is fixed on the fixed block 601, the ejector pin 605 will push the movable block 603 downward, so that the top of the movable block 603 leaves the fixed block 601, and the water flow can flow from the top of the movable block 603 to the first water branch pipe 8. When the water temperature continues to rise, the movable block 603 will eventually block the second water branch pipe 9. At this time, the water can only flow out from the first water branch pipe 8, so that when the water temperature is low, the water flows directly into the water inlet pipe 11 from the second water branch pipe 9. When the water temperature is high, the water flows into the water inlet pipe 11 after the temperature is reduced by the radiator. The use of the regulating block can ensure that the water temperature is cooled at high temperature while reducing the cooling efficiency of the water at low temperature, so that the water temperature rises rapidly at low temperature, so that the lubricating oil temperature can be quickly increased to the process requirements of the unit.
