Description

Technical Field

[0001] The utility model relates to the technical field of lead-acid battery production, in particular to a battery paste cold air intervention cooling device. Background Art

[0003] The patent document with application number CN201620793692.4 and invention name "Battery Lead Paste and Paste Device" discloses a paste mixing device, including a paste mixing machine, a feed port is provided on the top of the paste mixing machine, and a feed hopper is provided above the feed port; a vibrating screen is provided in the feed port, a vibrating motor is provided on the left side of the feed port, and the vibrating screen is connected to the vibrating motor; an acid metering cylinder and a water metering cylinder are provided on the left and right sides of the feed hopper; the top and bottom of the acid metering cylinder are respectively connected to an acid inlet pipe and an acid outlet pipe, and the acid outlet pipe is connected to the top of the left side of the paste mixing machine; the top and bottom of the water metering cylinder are respectively connected to a water inlet pipe and a water outlet pipe, and the water outlet pipe is connected to the top of the right side of the paste mixing machine. The paste mixing machine is not provided with a cooling structure, and the natural cooling efficiency of the lead paste is affected by the ambient temperature, and the performance of different batches fluctuates greatly.

[0004] The patent document with application number CN202123454403.8 and invention name "An efficient cooling system for paste mixing" discloses a device that can use chilled water and cold air to cool a paste mixing machine. After the materials in the paste mixing machine are added and stirred, the chilled water enters the evaporator of the water-cooled freezer from the insulated water tank through the chilled water pump. After the chilled water is cooled in the water-cooled freezer, it returns to the insulated water tank and mixes with the original chilled water, so that the overall water temperature in the insulated water tank is maintained at about 10°C. During the operation of the water-cooled freezer, the condensed water in the cooling water tank enters the condenser of the water-cooled freezer through the cooling pump to cool the refrigerant of the water-cooled freezer to maintain the refrigeration capacity of the water-cooled freezer. After absorbing heat, the condensed water enters the cooling tower for cooling and then returns to the cooling water tank. The chilled water in the insulated water tank enters the water inlet of the air cooler through the second outlet, the delivery pump and the solenoid valve, cools the air in the air cooler to about 15°C and returns to the insulated water tank. The air cooler blows cold air into the cold air inlet of the paste mixing machine, cools the mixed paste and leaves from the cold air outlet. Another channel of chilled water in the insulated water tank passes through the second outlet and the delivery pump under the control of the solenoid valve and enters the cold water pipe in the jacket of the paste mixing machine, absorbs the heat released when the paste is mixed and returns to the insulated water tank.

[0005] This efficient cooling system for paste mixing uses chilled water and cold air to cool the paste mixing machine, and requires the construction of supporting water-cooled refrigerators, cooling water tanks, cold air fans, chilled water pumps, cooling pumps, conveying pumps, cooling towers and other ancillary equipment, and its equipment investment cost is relatively high. In winter, cold air outside the factory can be introduced into the factory to cool the paste mixing machine. When the outside temperature is low, the paste mixing machine is cooled by cold air from the outside, and when the outside temperature is high, the paste mixing machine is cooled by cold air fans, thereby reducing the equipment investment cost and production cost. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. During the working process of the utility model, when the outside air temperature is low, the outside cold air can be introduced into the jacket between the outer jacket and the paste mixing machine to cool the working paste mixing machine. When the outside air temperature is high, the cold air blower can be used to cool the working paste mixing machine. Therefore, the cost of plate production can be reduced.

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0037] Embodiment 1:

[0038] Reference Figure 1-Figure 2 As shown, a battery paste cold air intervention cooling device includes an outer cover 6, which is fixed on an outer jacket 2 outside a paste machine 1, and the upper and lower ends of the outer jacket 2 are fixedly connected with an air outlet pipe 11, and a plurality of annular tubes 3 are fixed in the jacket between the outer jacket 2 and the paste machine 1, and an inlet pipe 5 is fixed on the outer side of the annular tube 3, and the inlet pipe 5 is connected with the outer cover 6. A plurality of outlet pipes 4 are fixedly connected inside the annular tube 3, and the outer cover 6 is connected with an air inlet pipe 12, and an air conveyor 13 is installed on the air inlet pipe 12.

[0039] The upstream of the air inlet pipe 12 is connected to the first connecting pipe 14 and the second connecting pipe 17, and the second connecting pipe 17 is connected to the air cooler.

[0040] The upstream of the first connecting pipe 14 extends to the outside of the factory building where the paste mixing machine 1 is located, and a filter 15 is installed on the first connecting pipe 14 outside the factory building. A temperature sensor 16 is fixed to the first connecting pipe 14 outside the factory building.

[0041] A first solenoid valve 19 is installed on the first connecting pipe 14 , a second solenoid valve 18 is installed on the second connecting pipe 17 , and the temperature sensor 16 , the first solenoid valve 19 , the second solenoid valve 18 , the controller, the air cooler and the air delivery fan 13 are electrically connected.

[0042] In this embodiment, the temperature sensor 16 monitors the air temperature outside the factory in real time. When the temperature outside the factory is lower than 10°C, the temperature sensor 16 sends a signal to the controller. After receiving the signal, the controller closes the second solenoid valve 18 and the air cooler, opens the first solenoid valve 19, increases the speed of the air conveyor 13, and thus increases the air output of the air conveyor 13. At this time, the cold air outside the factory is introduced into the jacket between the paste machine 1 and the outer jacket 2, and the filter 15 can filter the air outside the factory. The cold air outside the factory is introduced into the jacket between the paste machine 1 and the outer jacket 2 and then discharged through the air outlet pipe 11. The paste machine 1 is cooled by the cold air outside the factory. It can reduce the cost in the plate production process.

[0043] When the temperature outside the factory building is higher than 10°C, the temperature sensor 16 sends a signal to the controller. After receiving the signal, the controller opens the second solenoid valve 18 and the air cooler, closes the first solenoid valve 19, and reduces the speed of the air delivery fan 13 to reduce the air delivery volume of the air delivery fan 13. The temperature of the cold air discharged from the air cooler is 5°C. In order to ensure that the cold air discharged from the air cooler can effectively cool the paste mixing machine 1. It is necessary to increase the contact time between the cold air and the paste mixing machine 1 to avoid waste caused by the low temperature of the cold air discharged from the air outlet pipe 11. After the cold air enters the outer cover 6, it is distributed into multiple ring pipes 3 through multiple inlet pipes 5. The cold air in the ring pipe 3 is discharged from the outlet pipe 4 and contacts with the paste mixing machine 1 to cool down the paste mixing machine 1.

[0044] Embodiment 2:

[0045] Based on Example 1, refer to Figure 1-Figure 2 As shown, an air volume adjustment component is provided on the outer cover 2 inside the outer cover 6.

[0046] The air volume adjustment assembly includes a plurality of openings on the outer cover 2 inside the outer cover 6, and the openings are arranged alternately with the inlet pipe 5. A plug block 7 is inserted in a sliding seal in the opening, and a support rod 8 is fixed on each of the plug blocks 7. The support rod 8 is fixedly connected to the connecting rod 9 in the outer cover 6. A plurality of electric telescopic rods 10 are fixed on the outer cover 6, and the telescopic ends of the electric telescopic rods 10 are fixedly connected to the connecting rod 9. The electric telescopic rods 10 are electrically connected to the controller.

[0047] When the temperature outside the factory building is lower than 10°C, in order to ensure the cooling efficiency of the paste machine 1 using the outside air, the controller starts multiple electric telescopic rods 10 at the same time after receiving the signal from the temperature sensor 16. The multiple electric telescopic rods 10 shrink and make the plug 7 withdraw from the opening. At this time, the jacket between the outer cover 2 and the paste machine 1 is connected to the outer cover 6 through the opening, and the air outlet area between the outer cover 6 and the jacket is increased, so that the amount of cold air flowing through the jacket can be increased, ensuring the effective cooling of the paste machine 1.

[0048] When the temperature of the outside air is lower than 5°C, in order to prevent the paste mixing machine 1 from being overcooled, the controller reduces the speed of the air conveying fan 13 and thereby reduces the air delivery volume of the air conveying fan 13. At the same time, the controller activates multiple electric telescopic rods 10, so that the plug block 7 enters the opening, and the opening is blocked by the plug block 7, thereby reducing the air flow in the jacket between the outer jacket 2 and the paste mixing machine 1, thereby preventing the paste mixing machine 1 from being overcooled.
