DETAILED DESCRIPTION

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] like Figure 1-5 As shown, a vacuum pump cooling water barrel includes a barrel body 1, a heat exchange tube 2 and a foam plate 3. The heat exchange tube 2 is spirally arranged along the inner wall of the barrel body 1. The inlet and outlet of the heat exchange tube 2 are both located at the bottom of the barrel body 1. The foam plate 3 is installed at the inner bottom of the barrel body 1 inside the heat exchange tube 2. An air intake pipe 4 extending upward from the barrel body 1 is provided at the upper end of the foam plate 3. A water inlet 102 and a water outlet 103 are provided on the side wall of the barrel body 1. When the temperature in the barrel is too high, cold air can be introduced into the air intake pipe 4 to allow the cold air to directly cool the circulating water, thereby achieving the purpose of rapid cooling. The upward arrangement of the air intake pipe 4 can also prevent the circulating water from flowing back.

[0024] In the above embodiment, the water inlet 102 and the water outlet 103 are arranged one above the other, and both the water inlet 102 and the water outlet 103 are horizontally tangent to the side of the barrel body 1. The water inlet 102 and the water outlet 103 are arranged opposite to each other in the circumferential direction. The circulating water enters the barrel from the upper water inlet 102, driving the water flow in the barrel to form a vortex, and under the action of the lower water outlet 103, a water flow that does not interfere with the heat exchange tube 2 and spirals downward is formed, which also increases the flow rate and improves the heat exchange efficiency. The inlet and outlet positions of the heat exchange tube 2 are adjacent to each other, which is convenient for coating the inlet and outlet pipes with insulation materials to reduce energy loss; the lower end of the barrel body 1 is provided with a lifting stand 101 to facilitate the connection of the inlet and outlet of the heat exchange tube 2. The foam plate 3 has a cavity 301 inside, and an air hole 302 connected to the cavity 301 is provided at the upper end of the foam plate 3. After the cold air enters the cavity 301, it forms bubbles through the dense air holes 302 and enters the circulating water, thereby increasing the contact area with the circulating water and improving the heat exchange efficiency.

[0025] In the above embodiment, a barrel cover 6 is provided at the upper end of the barrel body 1, and the air intake pipe 4 passes through the barrel cover 6. A pressure relief structure is provided on the barrel cover 6. The barrel cover 6 plays a role of heat preservation to avoid energy loss, and the pressure relief structure can provide an exhaust channel when cold air enters the circulating water; a one-way valve 5 from outside to inside is provided on the air intake pipe 4, and the one-way valve 5 is located above the barrel cover 6 to balance the air pressure and avoid the circulating water from flowing back along the air intake pipe 4. The pressure relief structure includes a piston 7, a spring 8 and a support platform 9. A pressure relief hole 104 is provided on the barrel cover 6. The piston 7 is slidably connected in the pressure relief hole 104. The support platform 9 is installed above the pressure relief hole 104. The spring 8 is elastically connected between the support platform 9 and the piston 7. During pressure relief, the gas pushes the piston 7 and compresses the spring 8, and is discharged from between the piston 7 and the pressure relief hole 104. When pressure relief is not required, the pressure relief hole 104 is closed by the spring 8. A plurality of supporting feet 701 are provided on the side surface of the lower end of the piston 7. The plurality of supporting feet 701 are all slidably connected to the pressure relief hole 104. During pressure relief, the plurality of supporting feet 701 are still located in the pressure relief hole 104 under the action of the spring 8, so as to prevent the piston 7 from falling out of the pressure relief hole 104 as a whole, causing the pressure relief hole 104 to be normally open. A contact piece 10 is provided at the upper end of the barrel cover 6, and an alarm light 11 is provided at the upper end of the support platform 9. One end of the contact piece 10 extends between the piston 7 and the support platform 9. The contact piece 10, the alarm light 11 and the piston 7 can be connected to form a circuit. When the piston 7 releases pressure, it will touch the contact piece 10 upwards. At this time, the touch triggers the electrically connected alarm light 11 and it flashes, reflecting the working status of the pressure relief structure.

[0026] Description of the working method of this utility model:

[0027] Connect the water inlet 102 and the water outlet 103 to the external vacuum pump circulating water pipeline respectively, connect the inlet and outlet of the heat exchange tube 2 to the external air conditioning pipeline respectively, and connect the air intake pipeline 4 of the foaming board 3 through the three-way valve and the manual valve. After the pipelines are installed, check the air tightness of the barrel cover 6 and put it into use. When the beer production line operates normally, the vacuum pump continuously works to generate a large amount of heat. The circulating water used to dissipate the heat of the vacuum pump body enters the barrel through the water inlet 102. Under the refrigeration effect of the external air conditioner, the cold air continuously exchanges heat with the circulating water in the barrel through the heat exchange tube 2 to cool the circulating water and ensure the cooling effect of the circulating water on the vacuum pump. When the beer enters the peak sales season, the production line operates uninterruptedly, and the vacuum pump operates at full load to generate a large amount of heat. At this time, it is necessary to open the valve of the pipeline where the air inlet pipe 4 of the foaming plate 3 is located to allow the cold air to directly enter the barrel and form dense bubbles through the air holes 302 of the foaming plate 3 to directly cool the circulating water and ensure the cooling effect of the circulating water. In this process, the pressure relief structure provides an exhaust channel for the cold air in the barrel, and when exhausting, the piston 7 intermittently touches or continuously touches the contact piece 10 and turns on the alarm light 11, and its working status is fed back by flashing. After the air inlet pipe 4 of the foaming plate 3 is closed, the pressure relief structure is automatically closed under the action of the spring 8 to avoid energy loss in the barrel.

[0028] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
