Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology, and in particular to a flow monitoring device for a cooling system of heat treatment equipment. Background Technology

[0002] Heat treatment equipment is usually equipped with a cooling system. Existing technology cooling systems generally only have pressure detection at the water inlet. However, this setup means that when the water passage at the end of the cooling system becomes blocked, the pressure detection cannot detect it, which reduces the overall reliability of the cooling system. Utility Model Content

[0003] The technical solution to be solved by this utility model is to provide a flow monitoring device for a cooling system of a heat treatment equipment. This cooling system can monitor the flow rate of the water at the end, so that when a blockage occurs at the end, it can be detected immediately, and the overall reliability is high.

[0004] The technical solution adopted by this utility model is: a flow monitoring device for a cooling system of a heat treatment equipment, including a water tank at the end of the cooling system and an outlet pipe for supplying cooling water flowing through the cooling system into the water tank. It also includes a monitoring box and a float level sensor switch installed inside the monitoring box for detecting the water level in the monitoring box. The outlet of the outlet pipe faces into the monitoring box. A monitoring water pipe for supplying water from the monitoring box to the water tank is provided on the lower outer wall of one side of the monitoring box, and the water flow rate of the monitoring water pipe is less than the water flow rate of the outlet pipe.

[0005] Preferably, the float level sensor switch is located on the inner wall of the upper part of one side of the monitoring box.

[0006] Preferably, the upper part of one side of the monitoring box is also provided with an overflow port for water to overflow from the monitoring box.

[0007] Preferably, one end of the water outlet pipe is fixed to the upper inner wall of the first side of the monitoring box, the float level sensor switch is fixed to the upper inner wall of the second side of the monitoring box, the monitoring water pipe is fixed to the lower outer wall of the second side, the overflow port is located on the upper part of the second side, and the first side and the second side are arranged opposite to each other.

[0008] Preferably, there are at least two monitoring boxes, and the two monitoring boxes are integrally formed. Each monitoring box is equipped with a water outlet pipe, a float level sensor switch, a monitoring water pipe, and an overflow port.

[0009] Preferably, the water tank is provided with an mounting plate on its upper part, and the monitoring box is mounted on the mounting plate.

[0010] Compared with the prior art, the present invention has the following advantages: the flow monitoring device with this structure is relatively simple and can easily detect the water flow rate of the outlet pipe. In this way, when the water flow rate is abnormal, it is easy to find out that there is a problem with the cooling system, so that the overall reliability of the cooling system is high.

[0011] Install an overflow outlet so that overflowing water can flow out easily.

[0012] The system is equipped with at least two monitoring boxes and their internal components, so that the flow monitoring device can still perform its monitoring function even if one of the monitoring boxes and its internal components malfunctions.

[0013] A mounting plate is installed to facilitate the installation of the monitoring box, and the monitoring water pipe on the monitoring box can flow directly into the water tank. Attached Figure Description

[0016] As shown in the figure: 1. Water tank; 2. Water outlet pipe; 3. Monitoring box; 4. Float level sensor switch; 5. Monitoring water pipe; 6. Overflow port; 7. Mounting plate. Detailed Implementation

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] Example 1:

[0019] A flow monitoring device for a cooling system of a heat treatment equipment, wherein the cooling system includes an outlet pipe 2 at the end and a water tank 1 for receiving cooling water flowing from the outlet pipe 2 that has passed through the heat treatment equipment. A mounting plate 7 is provided above the water tank 1, and the flow monitoring device is mounted on the mounting plate 7.

[0020] The flow monitoring device includes a monitoring box 3 and a float level sensor switch 4. The monitoring box 3 is fixed on the mounting plate 7. A monitoring water pipe 5 is provided on the outer side of its lower front end for draining water from the monitoring box 3 into the water tank 1. A float level sensor switch 4 is provided on the inner side of the upper front end of the monitoring box 3. Since the float level sensor switch 4 is a conventional product in the prior art and can detect the liquid level height, it is not described in detail here. In actual use, the float level sensor switch 4 needs to be connected to the controller of the cooling system to transmit the detected liquid level data to the controller at all times. The outlet of the water pipe 2 is fixed on the inner side of the upper rear end of the monitoring box 3, and the diameter of the outlet of the water pipe 2 is larger than the diameter of the outlet of the monitoring water pipe 5, that is, the water flow rate of the outlet of the water pipe 2 is greater than the water flow rate of the monitoring water pipe 5.

[0021] The working principle of this embodiment is as follows: Water outlet pipe 2 discharges cooling water into monitoring box 3, while monitoring water pipe 5 discharges cooling water from monitoring box 3 into water tank 1. However, because the water flow rate of monitoring water pipe 5 is less than that of water outlet pipe 2, the water level in monitoring box 3 will rise until it overflows from the top of monitoring box 3. At this time, the float level sensor switch 4 can detect that the water level in monitoring box 3 exceeds a certain value, that is, the water flow rate is normal. However, when the cooling system malfunctions, that is, when water outlet pipe 2 basically does not discharge water or discharges very little water, the water level in monitoring box 3 will be almost zero. In other words, the float level sensor switch 4 cannot detect the water level in monitoring box 3. This allows it to be determined that the cooling system is malfunctioning, and the controller needs to issue an alarm.

[0022] Example 2:

[0023] The difference from Embodiment 1 is that the monitoring box 3 in Embodiment 2 is provided with an overflow port 6 at the upper front end, and the position of the overflow port 6 is higher than the liquid level position that the float liquid level sensor switch 4 can detect. In this way, the cooling water in the monitoring box 3 does not need to overflow from the top of the monitoring box 3, but can overflow from the overflow port 6.

[0024] Example 3:

[0025] The difference from Embodiment 2 is that in Embodiment 3, there are three monitoring boxes 3 and their internal components, and the three monitoring boxes 3 are arranged side by side and integrally formed. Two mounting plates 7 are installed above the water tank 1, and the whole formed by the three monitoring boxes 3 is fixed on the two mounting plates 7.

[0026] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.

[0027] For those skilled in the art, various changes and modifications will undoubtedly be apparent after reading the above description. Therefore, the appended claims should be considered as covering all changes and modifications that encompass the true intent and scope of this utility model. Any and all equivalent scope and content within the scope of the claims should be considered as still falling within the intent and scope of this utility model.
