Description

Technical Field

[0001] The utility model relates to the technical field of PVC water supply pipe production, in particular to an automatic water control and constant temperature device for PVC water supply pipe production. Background Art

[0002] During the production process, PVC water supply pipes are cooled and shaped after being heated. Existing cooling equipment uses a pipe rack mounted on top of a pool of water, with a spray mechanism installed above the pool. The pool is connected to the spray mechanism's water inlet via a water pump. During cooling, the pipe is placed on the rack, and the spray mechanism sprays cold water on the pipe to cool it. The cooling water flows into the pool and is then fed back to the spray mechanism, recycling water. As the cooling process progresses, the cooling water absorbs heat from the pipe and gradually heats up. To ensure effective cooling, it must be cooled. There are two main existing cooling methods: one is to manually open a drain valve to drain the hot water from the pool and simultaneously open a fill valve to add new cold water to the pool. This method is relatively cumbersome. The other method uses a float switch to control the water inlet and outlet. This method results in low water intake and slow cooling when the water pressure in the workshop is low. It is also prone to damage and requires frequent shutdowns for replacement, disrupting normal production.

[0003] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the Invention

[0004] The purpose of this utility model is to address the deficiencies of the existing technology and thus provide a scientifically designed automatic water control and constant temperature device for PVC water supply pipe production, which can automatically adjust the cooling water temperature, does not affect the cooling speed due to the water pressure in the workshop, and is highly practical.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an automatic water control and constant temperature device for the production of PVC water supply pipes, including a circulating water pool, a temperature sensor, a microcontroller, and a water supply pneumatic valve installed on the water supply port of the circulating water pool and a water discharge pneumatic valve installed on the water discharge port of the circulating water pool. The temperature sensor monitors the water temperature in the circulating water pool and transmits the water temperature information to the microcontroller. The microcontroller controls the opening and closing of the water supply pneumatic valve and the water discharge pneumatic valve according to whether the water temperature information exceeds a set range.

[0006] Based on the above, it also includes a float level gauge, which monitors the water level in the circulating water pool and transmits the water level information to the microcontroller; when the water level information is lower than the set threshold, the microcontroller controls the water supply pneumatic valve to open, and when the water level information is higher than the set threshold, the microcontroller controls the drainage pneumatic valve to open.

[0007] Based on the above, the circulating water pool is divided into a front water pool and a rear water pool by a middle partition. A temperature sensor, a water supply pneumatic valve, a drainage pneumatic valve and a float level gauge constitute a set of control components. A set of control components is installed on each of the front water pool and the rear water pool, and the two sets of control components are controlled by a microcontroller.

[0008] Based on the above, the water supply pneumatic valve and the drainage pneumatic valve are both installed at the bottom of the circulating water pool, and a water supply pipe is also installed on the water supply port of the circulating water pool, and the water outlet end of the water supply pipe extends to the upper part of the circulating water pool.

[0009] Based on the above, the bottom of the circulating water pool is provided with supporting legs.

[0010] The present invention has substantial features and progress over the prior art. Specifically, the present invention can set a temperature range by setting the microcontroller, and compare it with the water temperature in the pool measured by the temperature sensor. When the water temperature in the pool exceeds the set temperature upper limit, the microcontroller controls the water supply pneumatic valve and the drainage pneumatic valve to open, discharging hot water while replenishing cold water, until the water temperature in the pool is lower than the set temperature lower limit, and then controls the water supply pneumatic valve and the drainage pneumatic valve to close, thereby achieving automatic cooling. At the same time, the pneumatic valve itself has power, and when the water pressure in the workshop is low, it does not affect the flow rate. The pneumatic valve has the advantages of scientific design, automatic adjustment of cooling water temperature, no effect of workshop water pressure on cooling speed, and strong practicality.

[0011] Furthermore, the setting of the float level gauge can automatically drain water when the water level in the pool is too high, and automatically replenish water when the water level in the pool is too low, so that the water level is maintained in a good range; since half of the pipe length is relatively long, the circulating water pool is divided into a front water pool and a rear water pool, which is convenient for receiving cooling water for the front and rear halves of the pipe; the water replenishment pneumatic valve and the drainage pneumatic valve are centrally installed at the bottom of the circulating water pool for easy operation, and the setting of the water replenishment pipe allows cold water to be replenished from the top and hot water to be discharged from the bottom, thereby speeding up water changes.

[0015] The technical solution of the present utility model is further described in detail below through specific implementation methods.

[0016] like Figure 1 and Figure 2 As shown, an automatic water control and constant temperature device for the production of PVC water supply pipes includes a circulating water pool 1, a temperature sensor 2, a microcontroller, a water supply pneumatic valve 3 installed on the water supply port of the circulating water pool 1, and a water discharge pneumatic valve 4 installed on the water discharge port of the circulating water pool 1. The microcontroller can specifically adopt an STM32 single-chip microcomputer. The temperature sensor 2 monitors the water temperature in the circulating water pool 1 and transmits the water temperature information to the microcontroller. The microcontroller controls the opening and closing of the water supply pneumatic valve 3 and the water discharge pneumatic valve 4 according to whether the water temperature information exceeds a set range.

[0017] During specific use, the heated and shaped pipe is placed on the top of the circulating water pool 1, and the spray mechanism sprays cooling water on the pipe. The cooling water after heat exchange flows into the circulating water pool 1 and is pumped into the spray mechanism for repeated use; when the temperature sensor 2 measures that the water temperature in the pool exceeds the set temperature upper limit, the microcontroller controls the water supply pneumatic valve 3 and the drainage pneumatic valve 4 to open, discharging hot water and replenishing cold water until the water temperature in the pool is lower than the set temperature lower limit, and then controls the water supply pneumatic valve 3 and the drainage pneumatic valve 4 to close, realizing automatic cooling. At the same time, the pneumatic valve itself has power, and when the water pressure in the workshop is low, it does not affect the cooling speed.

[0018] In order to prevent the water level in the pool from being too high or too low, the automatic water control and constant temperature device for the production of PVC water supply pipes also includes a float level gauge 5, which monitors the water level in the circulating water pool 1 and transmits the water level information to the microcontroller; when the water level information is lower than the set threshold, the microcontroller controls the water supply pneumatic valve 3 to open and replenish cooling water; when the water level information is higher than the set threshold, the microcontroller controls the drainage pneumatic valve 5 to open and drain the cooling water.

[0019] Since the length of the pipe is relatively long, in order to facilitate the reception of sprayed cooling water, the circulating water pool is divided into a front water pool 11 and a rear water pool 12 by a middle partition, which respectively receive the cooling water of the front half and the rear half of the pipe. A temperature sensor 2, a water supply pneumatic valve 3, a drainage pneumatic valve 4 and a float level gauge 5 constitute a set of control components. A set of control components is installed on each of the front water pool 11 and the rear water pool 12, and the two sets of control components are controlled by a microcontroller.

[0020] To facilitate centralized operation, a support leg 6 is provided at the bottom of the circulating water pool 1. The water supply pneumatic valve 3 and the drainage pneumatic valve 4 are both installed at the bottom of the circulating water pool 1. A water supply pipe 7 is also installed on the water supply port of the circulating water pool 1. The water outlet end of the water supply pipe 7 extends to the upper part of the circulating water pool 1. In this way, cold water can be replenished from the top and hot water can be discharged from the bottom, thereby speeding up the water change.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for which protection is requested in the utility model.
