Description

Technical Field

[0001] This utility model relates to the field of integrated cooling and heating equipment technology, specifically to an automatic liquid replenishment device for the water tank of an integrated cooling and heating equipment. Background Technology

[0002] The integrated heating and cooling machine consists of two parts: a heating section and a cooling section. It offers precise temperature control and is widely used in industries such as injection molding, chemicals, rubber extrusion, reactors, and blow molding. The integrated heating and cooling machine allows for switching between these sections, accelerating production, reducing energy consumption, improving molding efficiency, minimizing defects, and reducing the production of defective products.

[0003] Traditional integrated heating and cooling systems typically require manual periodic checks of the water tank level and manual replenishment. This method is not only tedious and time-consuming, but also prone to human error leading to excessively low water levels, affecting equipment operation and even causing damage. Some systems use float valves for automatic water replenishment, but these valves are prone to malfunction due to blockages or mechanical failures, resulting in untimely or excessive water replenishment, affecting the stability and safety of the equipment.

[0004] Therefore, an automatic liquid replenishment device for the water tank of an integrated heating and cooling machine is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic liquid replenishment device for the water tank of a combined heating and cooling machine in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] An automatic liquid replenishment device for a water tank in a combined heating and cooling unit includes a water tank body and a return water tank. The bottom surface of the water tank body is provided with a first water inlet, and the bottom surface of the return water tank is provided with a second water outlet. A connecting pipe is fixedly connected between the first water inlet and the second water outlet. The top surface of the water tank body and the return water tank is covered with a tank cover assembly, and a liquid level sensor is provided on the tank cover assembly for real-time and accurate monitoring of the liquid level in the water tank body. A controller is fixedly installed on the top surface of the tank cover assembly, and a water supply pipe is fixedly connected to the input end of the tank cover assembly for connection with a water supply device. A solenoid valve is provided on the water supply pipe for controlling the input and replenishment of water.

[0008] Furthermore, the surface of the water tank body is provided with a first drain outlet, and the surface of the return water tank is provided with a return water outlet, wherein the first drain outlet is connected to the input pipe of the integrated cooling and heating unit, and the return water outlet is connected to the return water pipe of the integrated cooling and heating unit.

[0009] Furthermore, the water tank body is made of transparent material, and scale lines are provided on the surface of the water tank body for observing the liquid level inside the water tank body.

[0010] Furthermore, the tank cover assembly includes a cover body that is fixedly sleeved on the top surface of the water tank body and the return water tank, and two sets of limiting frames are provided on the inner top surface of the cover body, which are respectively inserted into the top of the water tank body and the return water tank. The cover body is provided with a mounting support seat, and a water filling pipe is fixedly inserted into the cover body.

[0011] Furthermore, the liquid level sensor is fixed on the top surface of the mounting support, and its detection end is located inside the water tank body.

[0012] Furthermore, the bottom end of the water inlet pipe is located inside the water tank body, and there is a gap between the water inlet pipe and the inner bottom of the water tank body.

[0013] The beneficial effects of this utility model are as follows:

[0014] The system utilizes a main water tank and a return water tank for liquid storage and circulation. These two tanks are connected by a connecting pipe, ensuring liquid flow between them and reducing the impact of water flow on the main water tank during return, which could cause water surface sloshing and affect the accuracy of the level sensor's monitoring of the water level. A cover assembly seals both the main water tank and the return water tank to prevent liquid evaporation or contamination. The level sensor monitors the liquid level in the main water tank in real time and transmits the data to the controller. When the liquid level falls below a preset value, the controller opens a solenoid valve, allowing water to flow into the main water tank through the water supply pipe until the liquid level reaches the preset value, thus achieving automatic water replenishment.

[0024] like Figures 1 to 4As shown, an automatic liquid replenishment device for a water tank in a combined heating and cooling unit includes a water tank body 1 and a return water tank 2. The bottom surface of the water tank body 1 is provided with a first water inlet 11, and the bottom surface of the return water tank 2 is provided with a second drain outlet 21. A connecting pipe 3 is fixedly connected between the first water inlet 11 and the second drain outlet 21. The top surface of the water tank body 1 and the return water tank 2 is covered with a tank cover assembly 4, and a liquid level sensor 5 is provided on the tank cover assembly 4 for real-time and accurate monitoring of the liquid level in the water tank body 1. A controller 6 is fixedly installed on the top surface of the tank cover assembly 4, and a water supply pipe 7 is fixedly connected to the input end of the tank cover assembly 4 for connection with water supply equipment. A solenoid valve 8 is provided on the water supply pipe 7 for controlling the input and replenishment of water. More specifically, liquid storage and circulation are achieved through the water tank body 1 and the return water tank 2. The water tank body 1 and the return water tank 2 are connected by a connecting pipe 3 to ensure that the liquid can flow between the two and reduce the impact of water flow on the water in the water tank body 1 during return water, which would cause water surface sloshing and affect the monitoring accuracy of the water level sensor 5 on the water level in the water tank body 1. The water tank body 1 and the return water tank 2 are sealed by the tank cover assembly 4 to prevent liquid evaporation or contamination. The liquid level sensor 5 monitors the liquid level in the water tank body 1 in real time and transmits the data to the controller 6. When the liquid level is lower than the preset value, the controller 6 opens the solenoid valve 8, allowing water to flow into the water tank body 1 through the water supply pipe 7 until the liquid level reaches the preset value, thereby realizing automatic water replenishment.

[0025] The surface of the water tank body 1 is provided with a first drain outlet 12, and the surface of the return water tank 2 is provided with a return water outlet 22. The first drain outlet 12 is connected to the input pipe of the integrated cooling and heating unit, and the return water outlet 22 is connected to the return water pipe of the integrated cooling and heating unit. More specifically, the first drain outlet 12 of the water tank body 1 and the return water outlet 22 of the return water tank 2 are respectively connected to the input pipe and the return water pipe of the integrated cooling and heating unit, forming a closed circulation system. This ensures efficient circulation of liquid between the integrated cooling and heating unit and the liquid replenishment device, while avoiding external contamination.

[0026] The water tank body 1 is made of transparent material, and scale lines are provided on the surface of the water tank body 1 for observing the liquid level inside the water tank body 1. More specifically, by making the water tank body 1 of transparent material and marking it with scale lines, the operator can intuitively observe the liquid level inside the water tank.

[0027] The tank cover assembly 4 includes a cover 401 fixedly fitted onto the top surface of the water tank body 1 and the return water tank 2. Two sets of limiting frames 402 are provided on the inner top surface of the cover 401, and are respectively inserted into the top of the water tank body 1 and the return water tank 2. A mounting support 403 is provided on the cover 401, and a water inlet pipe 404 is fixedly inserted into the cover 401. More specifically, the edge of the cover 401 and the limiting frames 402 on the inner top of the cover 401 allow it to be inserted into the top of the water tank body 1 and the return water tank 2, thus fixing the cover 401 to the top of the water tank body 1 and the return water tank 2. The mounting support 403 provides a mounting base for the level sensor 5, and water can be introduced into the interior of the water tank body 1 through the water inlet pipe 404.

[0028] The liquid level sensor 5 is fixed to the top surface of the mounting support 403, and its detection end is located inside the water tank body 1. More specifically, the liquid level sensor 5 is fixed to the top surface of the mounting support 403, and its detection end is located inside the water tank body 1, enabling real-time monitoring of liquid level changes inside the water tank body 1.

[0029] The bottom end of the water inlet pipe 404 is located inside the water tank body 1, and there is a gap between the water inlet pipe 404 and the inner bottom of the water tank body 1. More specifically, a certain gap is maintained between the water inlet pipe 404 and the inner bottom of the water tank body 1 to prevent the water discharged from the outlet of the water inlet pipe 404 from colliding with the water in the water tank body 1 during replenishment, which would cause the water to slosh inside the water tank body 1 and affect the monitoring accuracy.

[0030] In summary: Liquid storage and circulation are achieved through the water tank body 1 and the return water tank 2. The water tank body 1 and the return water tank 2 are connected by a connecting pipe 3 to ensure that the liquid can flow between the two and reduce the impact of water flow on the water in the water tank body 1 during return, which would cause water surface sloshing and affect the monitoring accuracy of the water level sensor 5. The water tank body 1 and the return water tank 2 are sealed by the tank cover assembly 4 to prevent liquid evaporation or contamination. The liquid level sensor 5 monitors the liquid level in the water tank body 1 in real time and transmits the data to the controller 6. When the liquid level is lower than the preset value, the controller 6 opens the solenoid valve 8, allowing water to flow into the water tank body 1 through the water supply pipe 7 until the liquid level reaches the preset value, thereby realizing automatic water replenishment.
