[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figure 1-4 The present invention will describe the above technical solution in detail through the following embodiments:

[0028] A constant temperature storage device for nitrile latex, comprising:

[0029] Water tank 2 includes a tank body 21 for holding heat exchange fluid. The tank body 21 is equipped with a temperature regulating component 26 for regulating the temperature of the heat exchange fluid. The tank body 21 is connected to several storage tanks 1 through a water supply pipe 3. Each storage tank 1 includes a tank body 11 connected in series. Each tank body 11 has a cavity 12 inside. The water supply pipe 3 includes a circulation pump 31 for pumping the heat exchange fluid into the cavities 12 of all the tank bodies 11 simultaneously.

[0030] Storage tank 1 is used to store nitrile latex.

[0031] The top of the tank 21 is symmetrically provided with a return water pipe 22 and an inlet water pipe 23. The inlet water pipe 23 is used to replenish the heat exchange fluid into the tank 21, and the return water pipe 22 is used to connect to the storage tank 1 to receive the heat exchange fluid returned from the storage tank 1.

[0032] The temperature control component 26 can employ a known compression heat pump, providing both cooling and heating functions. Its working principle involves a four-step cycle: compression → condensation → expansion → evaporation, transferring heat.

[0033] When heating, heat is absorbed from the external environment and released into the heat exchange fluid inside the chamber 21;

[0034] During cooling, the system circulates in reverse, transferring heat from the heat exchange fluid inside the housing 21 to the external environment.

[0035] Similar to the heating and cooling functions of an air conditioner.

[0036] It heats the heat exchange fluid when the external ambient temperature is low, and cools the heat exchange fluid when the external ambient temperature is high.

[0037] A water outlet pipe 24 is welded to one side of the bottom of the housing 21. The water outlet pipe 24 is connected to the circulating pump 31. A second temperature sensing component 25 is threaded onto the water outlet pipe 24. The second temperature sensing component 25 is used to detect the temperature of the heat exchange fluid discharged from the water outlet pipe 24.

[0038] Under heating conditions:

[0039] When the value detected by the second temperature sensing component 25 is lower than the set temperature, the temperature regulation component 26 starts to work.

[0040] When the value detected by the second temperature sensing component 25 is higher than the set temperature, the temperature regulation component 26 stops working.

[0041] In cooling mode:

[0042] Temperature regulation component 26 reverses circulation.

[0043] When the value detected by the second temperature sensing component 25 is higher than the set temperature, the temperature regulation component 26 starts to work.

[0044] When the value detected by the second temperature sensing component 25 is lower than the set temperature, the temperature regulation component 26 stops working.

[0045] The tank 11 includes an inner tank 111, an outer shell 112 covering the inner tank 111, a cavity 12 located between the inner tank 111 and the outer shell 112, and an insulation layer 13 covering the outer shell 112.

[0046] The inner tank 111 and the outer shell 112 are welded together, and the insulation layer 13 is used to reduce the temperature exchange between the tank 11 and the outside.

[0047] A first liquid inlet pipe 14 is provided at the bottom of one side of the outer casing 112. The first liquid inlet pipe 14 is connected to the water supply pipe 3, and a second liquid inlet pipe 15 is provided at the top of the same side.

[0048] The heat exchange fluid enters the bottom of the cavity 12 from the first inlet pipe 14 and then flows upward.

[0049] The second inlet pipe 15 of the last storage tank 1 can be sealed using a sealing device such as a sealing flange.

[0050] A first drain pipe 16 is provided on the top of the outer side of the outer shell 112 and at a position symmetrical to the second inlet pipe 15. The first drain pipe 16 is connected to the second inlet pipe 15 of the adjacent storage tank 1 or to the box body 21 for discharging the heat exchange liquid.

[0051] The heat exchange fluid is discharged from the first drain pipe 16 of the last storage tank 1, and then enters the cavity 12 of the next storage tank 1 from the second inlet pipe 15 of the next storage tank 1. It mixes with the heat exchange fluid that enters from the first inlet pipe 14 at the bottom of the storage tank 1, and then flows to the next storage tank 1 from the first drain pipe 16 at the top of the storage tank 1.

[0052] Finally, the heat exchange fluid is discharged from the first drain pipe 16 of the storage tank 1 at the front end and returns to the tank 21 through the return water pipe 22.

[0053] A first temperature sensing component 17 is provided at the first drain pipe 16, which is used to detect the temperature of the liquid inside the first drain pipe 16.

[0054] The first temperature sensing component 17 can detect the temperature of the heat exchange fluid discharged from the first drain pipe 16 of each storage tank 1, and then obtain the temperature of the heat exchange fluid input to the storage tank 1 based on the second temperature sensing component 25, thereby obtaining the temperature range inside the storage tank 1.

[0055] The water supply pipeline 3 also includes a main water supply pipe 32, one end of which is connected to the circulating pump 31. Several water supply branch pipes 34 are connected in parallel in the middle of the main water supply pipe 32, and each water supply branch pipe 34 is connected to a first liquid inlet pipe 14.

[0056] A first valve 33 is threadedly connected between the water supply main pipe 32 and the circulating pump 31. The first valve 33 is used to manually control the on / off state of the water supply main pipe 32.

[0057] The circulating pump 31 pumps the heat exchange liquid in the tank 21 out of the outlet pipe 24, then into the water supply main pipe 32, then into the first liquid inlet pipe 14 through the water supply pipe 34, and finally into the storage tank 1.

[0058] The water supply pipe 34 is equipped with a proportional valve 35 and a flow meter 36. The flow meter 36 is used to detect the flow rate in the water supply pipe 34, and the proportional valve 35 is used to control the flow rate in the water supply pipe 34.

[0059] If the temperature of the heat exchange fluid discharged from storage tank 1 differs too much from the temperature of the heat exchange fluid input to storage tank 1, the proportional valve 35 can be controlled to change the flow rate in the water supply pipe 34 connected to storage tank 1, thereby ensuring temperature stability.

[0060] When the temperature of the heat exchange fluid discharged from a certain storage tank 1 differs too much from the temperature of the heat exchange fluid discharged from the other storage tanks 1, the proportional valve 35 can be controlled to change the flow rate in the water supply pipe 34 connected to that storage tank 1, thereby ensuring temperature stability.

[0061] The flow data detected by the flow meter 36 can be used as the basis for the operation of the proportional valve 35.

[0062] Working principle:

[0063] Taking the heating mode as an example:

[0064] Heat exchange fluid is added to the tank 21 through the water inlet pipe 23, and the temperature of the heat exchange fluid is adjusted through the temperature regulating component 26.

[0065] Place the nitrile latex into storage tank 1.

[0066] Control the operation of the circulating pump 31 to pump the heat exchange liquid in the tank 21 out from the outlet pipe 24.

[0067] The second temperature sensing component 25 is used to detect the temperature of the heat exchange fluid discharged from the outlet pipe 24.

[0068] When the value detected by the second temperature sensing component 25 is lower than the set temperature, the temperature regulation component 26 starts to work.

[0069] When the value detected by the second temperature sensing component 25 is higher than the set temperature, the temperature regulation component 26 stops working.

[0070] The circulating pump 31 pumps the heat exchange liquid discharged from the outlet pipe 24 into the main water supply pipe 32, and then through the water supply pipe 34 into the first inlet pipe 14. The heat exchange liquid enters the bottom of the cavity 12 from the first inlet pipe 14 and then flows upward.

[0071] The heat exchange fluid is discharged from the first drain pipe 16 of the last storage tank 1, and then enters the cavity 12 of the next storage tank 1 from the second inlet pipe 15 of the next storage tank 1. It mixes with the heat exchange fluid that enters from the first inlet pipe 14 at the bottom of the storage tank 1, and then flows to the next storage tank 1 from the first drain pipe 16 at the top of the storage tank 1.

[0072] Finally, the heat exchange fluid is discharged from the first drain pipe 16 of the storage tank 1 at the front end and returns to the tank 21 through the return water pipe 22.

[0073] The first temperature sensing component 17 can detect the temperature of the heat exchange fluid discharged from the first drain pipe 16 of each storage tank 1, and then obtain the temperature of the heat exchange fluid input to the storage tank 1 based on the second temperature sensing component 25, thereby obtaining the temperature range inside the storage tank 1.

[0074] If the temperature of the heat exchange fluid discharged from storage tank 1 differs too much from the temperature of the heat exchange fluid input to storage tank 1, the proportional valve 35 can be controlled to change the flow rate in the water supply pipe 34 connected to storage tank 1, thereby ensuring temperature stability.

[0075] When the temperature of the heat exchange fluid discharged from a certain storage tank 1 differs too much from the temperature of the heat exchange fluid discharged from the other storage tanks 1, the proportional valve 35 can be controlled to change the flow rate in the water supply pipe 34 connected to that storage tank 1, thereby ensuring temperature stability.
