Description

Technical Field

[0001] This utility model relates to the field of coolant purification technology, specifically to a grinding coolant purification and cooling device. Background Technology

[0002] In current grinding operations, coolant is sprayed onto the workpiece and then flows out from the coolant collection tank on the grinding machine base into the coolant circulation and filtration system.

[0003] First, the inlet of current grinding coolant circulation filtration systems is located at the top or upper part of the water tank, which is too high. The outlet of the grinding machine base needs a sufficient height difference with the inlet of the coolant circulation filtration system to ensure good circulation. This results in an excessively high overall height of the grinding machine base, which is detrimental to the placement of the grinding machine and the loading and unloading of workpieces. Second, grinding coolant contains a large amount of impurities such as iron filings and sand particles, which need to be separated to ensure grinding efficiency. However, the separation effect of existing circulation filtration systems is not ideal. Third, because grinding machines do not operate continuously, the flow rate of the discharged coolant to be purified is unstable, leading to an unstable flow rate into the circulation filtration system. Current coolant circulation filtration systems purify the incoming coolant in real time; when the flow rate is too high, the purification effect is poor, and when the flow rate is too low, the entire system wastes energy. Utility Model Content

[0004] To address at least one of the aforementioned technical problems, this utility model provides a grinding coolant purification and cooling device.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A grinding coolant purification and cooling device is provided, comprising a filter box and a refrigeration box, wherein the filter box includes a sedimentation chamber and a separation chamber that are independent of each other;

[0007] A magnetic separator is installed above the separation chamber, and a paper tape filter is installed below the magnetic separator. The separation chamber is connected to the refrigeration box.

[0008] The sedimentation tank has an inlet at the bottom and a magnetic plate on the bottom surface. A sewage pump is installed inside the tank, and a sedimentation gap is formed between the inlet of the sewage pump and the magnetic plate. The outlet of the sewage pump is connected to the magnetic separator. The sedimentation tank is equipped with a first liquid level sensor and a control switch. The first liquid level sensor is electrically connected to the control switch, and the control switch is electrically connected to the sewage pump.

[0009] Furthermore, the grinding coolant purification and cooling device also includes a sludge tank, which is located directly below the slag outlet of the magnetic separator and the paper tape filter.

[0010] Furthermore, an overflow port is provided at a high position on the inner wall of the refrigeration box, and the overflow port is connected to the separation chamber.

[0011] Furthermore, the refrigeration box is equipped with a refrigeration unit, and the refrigeration end of the refrigeration unit is located inside the refrigeration box.

[0012] Furthermore, the grinding coolant purification and cooling device also includes a low-level alarm, and a second liquid level sensor is provided inside the refrigeration box. The low-level alarm is electrically connected to the second liquid level sensor.

[0013] Furthermore, the refrigeration box is equipped with a water purification pump, the inlet of which is located inside the refrigeration box, and the outlet of which is connected to the coolant inlet pipe of the grinding machine.

[0014] Furthermore, the paper tape of the paper tape filter is laid to cover the top surface of the separation chamber.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model's grinding coolant purification and cooling device features an independent sedimentation chamber with a low inlet position, reducing the height of the grinding machine base. The sedimentation chamber contains a magnetic plate that coarsely separates iron filings, improving the purification effect. Simultaneously, a wastewater pump is activated based on a first liquid level sensor and a control switch, allowing the sedimentation chamber to store and settle water. Regardless of the coolant flow rate from the grinding machine, a stable flow rate is maintained to the magnetic separator above the separation chamber. The separation chamber does not operate when the coolant level in the sedimentation chamber is too low, thus improving the purification effect while saving energy. Attached Figure Description

[0020] Figure 3 A side view of the grinding coolant purification and cooling device of this invention is shown. Detailed Implementation

[0021] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0022] like Figures 1-3 As shown, the grinding coolant purification and cooling device of this utility model includes a filter box 2 and a refrigeration box 1. The filter box 2 includes a sedimentation chamber 21 and a separation chamber 22, which are independent of each other. A magnetic separator 4 is provided above the separation chamber 22, and a paper tape filter 5 is provided below the magnetic separator 4. The separation chamber 22 is connected to the refrigeration box 1. The sedimentation chamber 21 has a liquid inlet 9 at the bottom, a magnetic plate 13 on the bottom surface of the chamber, and a sewage pump 7 inside the chamber. A sedimentation gap is formed between the inlet of the sewage pump 7 and the magnetic plate 13, and the outlet of the sewage pump 7 is connected to the magnetic separator 4. The sedimentation chamber 21 is equipped with a first liquid level sensor 8 and a control switch. The first liquid level sensor 8 is electrically connected to the control switch, and the control switch is electrically connected to the sewage pump 7. A clean water pump 10 is provided on the refrigeration box 1. The inlet of the clean water pump 10 is located inside the refrigeration box 1, and the outlet of the clean water pump 10 is connected to the coolant inlet pipe of the grinding machine. The paper tape of the paper tape filter 5 is laid and covers the top surface of the separation chamber 22.

[0023] Purified coolant discharged from the grinding machine enters the sedimentation tank 21 through inlet 9. Magnetic plate 13 adsorbs some of the iron filings. Simultaneously, the first liquid level sensor 8 measures the water level in the sedimentation tank 21. When the water level reaches a certain height, a signal is sent to the control switch, which then activates the wastewater pump 7. Because the inlet is low, the grinding machine base does not need to be too high to create a sufficient height difference, thus lowering the grinding machine base. When the flow rate discharged from the grinding machine is not large, the coolant in the sedimentation tank 21 has sufficient time to settle, and impurities settle at the bottom. Since the inlet of wastewater pump 7 is located at a higher water level, wastewater pump 7 draws out relatively pure coolant and sends it to magnetic separator 4, reducing the purification pressure in separation tank 22 and improving the purification effect. At the same time, when wastewater pump 7 is not working, magnetic separator 4 and paper tape filter 5 do not need to work, saving energy. During periods of high coolant flow from the grinding machine, the discharge capacity of wastewater pump 7 is sufficient to promptly discharge the coolant from the sedimentation tank 21, preventing overflow. The preferred sedimentation chamber 21 is provided with an openable and closable drain port at its lower part, through which impurities deposited at the bottom of the sedimentation chamber 21 can be periodically removed. The magnetic separator sends the separated clean water to the paper tape filter 5, and after further purification by the paper tape filter, it flows into the separation chamber 22. The clean coolant in the separation chamber 22 flows into the refrigeration box 1, and the refrigeration box 1 cools the coolant and then sends it into the coolant inlet pipe of the grinding machine.

[0024] In some preferred embodiments, the grinding coolant purification and cooling device further includes a sludge tank 3, which is located directly below the slag outlets of the magnetic separator 4 and the paper tape filter 5. Impurities separated by the magnetic separator 4 and the paper tape filter 5 fall into the sludge tank 3 for easy cleaning. A refrigeration unit 6 is mounted on the refrigeration chamber 1, with its cooling end located inside the refrigeration chamber 1. An overflow port 12 is located at a high position on the inner wall of the refrigeration chamber 1, and the overflow port 12 is connected to the separation chamber 22. To achieve a better cooling effect, the volume of the refrigeration chamber 1 is not very large. When the water level in the refrigeration chamber 1 is too high, to prevent the coolant from overflowing, an overflow port 12 is provided at a high position on its inner wall, allowing excess coolant in the refrigeration chamber 1 to flow back into the separation chamber 22. The grinding coolant purification and cooling device also includes a low-level alarm (not shown in the figure). A second liquid level sensor 11 is installed in the refrigeration box. The low-level alarm is electrically connected to the second liquid level sensor 11. When the water level in the refrigeration box 1 is low, the low-level alarm will sound an alarm to avoid insufficient pure coolant being supplied to the grinding machine, which would result in unqualified parts processing.
