Description

Technical Field

[0001] The invention relates to the field of cooling machines, in particular to a self-cleaning cooling machine. Background Art

[0002] Equipment with heat sources used in production are generally equipped with coolers to assist in cooling the equipment with heat sources. After long-term use, dust, oil and bacteria are easily accumulated inside the cooler. At the same time, the coolant will inevitably be contaminated during the circulation process. Existing coolers need to be shut down for processing after being found to be dirty or bacterial. All coolant in the cooler cavity must be poured out, the cooler must be cleaned, and then replaced with new coolant. During the shutdown of the cooler, the equipment with heat sources it assists also needs to be shut down together. The shutdown procedures of many equipment are cumbersome, and shutdowns are bound to be accompanied by economic losses. For mass production, the longer the downtime, the greater the cost. In addition, some coolants with special ingredients are expensive, and it is also a large expense to replace the coolant as a whole. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a self-cleaning cooling machine to reduce the downtime of the equipment.

[0004] In order to solve the above technical problems, a technical solution adopted by the present invention is:

[0005] A self-cleaning cooling machine comprises a liquid inlet pipe, a recovery part, a purification part, a liquid delivery part, a first liquid discharge pipe, a second liquid discharge pipe, a liquid replenishing pipe, a liquid outlet pipe, a self-cleaning device and a sewage pipe;

[0006] The recovery part and the purification part are connected through the first liquid discharge pipe, and the purification part and the liquid delivery part are connected through the second liquid discharge pipe;

[0007] The liquid inlet pipe is arranged on the recovery part, and the first liquid discharge pipe is provided with a first valve;

[0008] The self-cleaning device is connected to the purification unit, the inlet of the sewage pipe is connected to the second liquid discharge pipe and a second valve is provided at the connection;

[0009] The second valve is used to control the liquid in the second liquid discharge pipe to flow to the sewage discharge pipe or to the liquid delivery part;

[0010] The liquid infusion tube and the liquid outlet tube are both arranged on the liquid delivery part.

[0011] The beneficial effects of the present invention are as follows: the inner cavity of the cooling machine is subdivided into three parts: a recovery part, a purification part and a liquid delivery part. When the purification part needs to be cleaned, the first valve and the second valve can be adjusted to close the connection between the recovery part, the purification part and the liquid delivery part, and at the same time, the self-cleaning device in the purification part is opened, then the recovered coolant will be accumulated in the recovery part, which will not affect the self-cleaning process of the purification part. At the same time, the purification part and the liquid delivery part are not connected, and the waste liquid in the self-cleaning process of the purification part can be discharged through the drain pipe, and the liquid replenishment pipe in the liquid delivery part can replenish the coolant, that is, during the cleaning process of the purification part, the liquid delivery part can also normally provide coolant for the equipment, and the equipment does not need to be shut down to wait for the end of the self-cleaning process of the purification part, which greatly reduces the downtime of the equipment.

[0016] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0017] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a self-cleaning cooling machine, comprising a liquid inlet pipe, a recovery part, a purification part, a liquid delivery part, a first liquid discharge pipe, a second liquid discharge pipe, a liquid replenishing pipe, a liquid outlet pipe, a self-cleaning device and a sewage pipe;

[0018] The recovery part and the purification part are connected through the first liquid discharge pipe, and the purification part and the liquid delivery part are connected through the second liquid discharge pipe;

[0019] The liquid inlet pipe is arranged on the recovery part, and the first liquid discharge pipe is provided with a first valve;

[0020] The self-cleaning device is connected to the purification unit, the inlet of the sewage pipe is connected to the second liquid discharge pipe and a second valve is provided at the connection;

[0021] The second valve is used to control the liquid in the second liquid discharge pipe to flow to the sewage discharge pipe or to the liquid delivery part;

[0022] The liquid infusion tube and the liquid outlet tube are both arranged on the liquid delivery part.

[0023] From the above description, it can be seen that the beneficial effects of the present invention are: the inner cavity of the cooling machine is subdivided into three parts: a recovery part, a purification part and a liquid delivery part. When the purification part needs to be cleaned, the first valve and the second valve can be adjusted to close the connection between the recovery part, the purification part and the liquid delivery part, and at the same time, the self-cleaning device in the purification part is opened, then the recovered coolant will accumulate in the recovery part, will not affect the self-cleaning process of the purification part, and at the same time, the purification part and the liquid delivery part are not connected, the waste liquid in the self-cleaning process of the purification part can be discharged through the drain pipe, and the liquid replenishment pipe in the liquid delivery part can replenish the coolant, that is, during the cleaning process of the purification part, the liquid delivery part can also normally provide coolant for the equipment, the equipment does not need to be shut down to wait for the cleaning process of the purification part to end, which greatly reduces the downtime of the equipment.

[0024] Further, the self-cleaning device includes a lotion pipe;

[0025] The lotion pipe is connected to the position of the first valve on the first liquid discharge pipe;

[0026] The first valve is used to control whether the liquid in the first liquid discharge pipe flowing to the purification part comes from the recovery part or the detergent pipe.

[0027] From the above description, it can be seen that the self-cleaning device of the purification section includes a detergent tube and is connected to the first valve. When the purification section needs to be cleaned, it is only necessary to adjust the first valve to allow the detergent to flow into the purification section through the detergent tube, while isolating the liquid from the recovery section. The purification device in the purification section can be cleaned without stopping.

[0028] Further, the self-cleaning device includes an ultrasonic cleaning device;

[0029] The ultrasonic cleaning device is arranged in the purification part and is located outside the purification device of the purification part.

[0030] From the above description, it can be seen that the self-cleaning device of the purification unit also includes an ultrasonic cleaning device, which is located outside the purification device of the purification unit. The purification device in the purification unit can be cleaned by turning on the ultrasonic cleaning device, thereby reducing the replacement frequency of the purification device.

[0031] Furthermore, the purification unit is also provided with an oil collection device, a filter and a third liquid discharge pipe;

[0032] The inlet of the oil collection device is connected to the inlet of the purification unit, the outlet of the oil collection device is connected to the inlet of the third drain pipe, the outlet of the third drain pipe is connected to the inlet of the filter, and the outlet of the filter is connected to the outlet of the purification unit;

[0033] The third liquid discharge pipe is connected to the second inlet of the sewage pipe and a third valve is provided at the connection, and the third valve is used to control the liquid in the third liquid discharge pipe to flow to the filter or the sewage pipe;

[0034] The inlet of the purification part is connected to the outlet of the first drain pipe, and the outlet of the purification part is connected to the inlet of the second drain pipe.

[0035] From the above description, it can be seen that the third drain pipe connected to the outlet of the oil collection device is connected to the second inlet of the drain pipe, and a third valve is provided at the connection point. After the oil collection device is cleaned, the waste liquid can be directly discharged through the drain pipe without passing through a filter, thereby extending the service life of the filter. The oil collection device and the filter are used as purification devices, the equipment is simple, easy to install, and can meet the coolant purification needs under general circumstances, with high cost performance.

[0036] Furthermore, the recovery part and the purification part as well as the purification part and the liquid delivery part are detachably connected.

[0037] From the above description, it can be seen that the recovery part and the purification part, as well as the purification part and the liquid delivery part are arranged to be detachably connected, which is more convenient when it is necessary to clean or replace a part of them. When cleaning the purification part, only the purification part can be disassembled while maintaining the normal operation of the liquid delivery part and the recovery part without stopping the machine, thereby greatly reducing the downtime of the equipment.

[0038] Furthermore, it also includes a detachable device, the detachable device includes a base, a first lifting rod and a second lifting rod;

[0039] The base is connected to the second lifting rod in a lifting manner, and the second lifting rod is connected to the first lifting rod in a lifting manner;

[0040] The four sides of the recovery portion are respectively detachably connected to at least one of the first lifting rods;

[0041] The four sides of the purification part are respectively detachably connected to at least one of the second lifting rods.

[0042] From the above description, it can be seen that the separation between the recovery part and the purification part and between the purification part and the liquid delivery part is completed by the lifting rod. The operation is simple and the structure of the detachable device is simple, which is easy to implement in practical applications. At least 4 detachable devices including a first lifting rod, a second lifting rod and a base are arranged, which are located on the four sides of the cooler, and the support is more stable. In addition, according to the different densities of different types of coolants in the cooler, detachable devices can be added, such as two detachable devices are arranged on each of the four sides, and a total of eight detachable devices are arranged to control the recovery part and the purification part, thereby increasing the stability of the cooler. Moreover, the recovery part and the purification part can be controlled respectively by manipulating the first lifting rod and the second lifting rod, and the object to be disassembled can be selected according to the needs of the specific situation, thereby increasing the flexibility of the cooler equipment during the disassembly process.

[0043] Furthermore, the first lifting rod is provided with a first hook, the second lifting rod is provided with a second hook at a position close to the recovery part and a third hook at a position close to the liquid delivery part;

[0044] The outer wall of the recovery part is provided with a first card slot, the outer wall of the purification part is provided with a second card slot near the recovery part and a third card slot near the liquid delivery part;

[0045] The first hook can be embedded in the first card slot, the second hook can be embedded in the second card slot, and the third hook can be embedded in the third card slot;

[0046] The first card slots are distributed on four sides of the outer wall of the recovery part;

[0047] The second card slots are distributed on four sides of the outer wall of the purification unit, and the third card slots are distributed on four sides of the outer wall of the purification unit.

[0048] It can be seen from the above description that the recovery part and the purification part are fixed to the detachable device through the cooperation between the card slots arranged thereon and the hooks arranged on the lifting rod, so as to realize the detachability between the recovery part and the purification part and between the purification part and the liquid delivery part. It is easy to realize by using the lifting rod as the detachable device; card slots are arranged on all four sides of the outer walls of the recovery part and the purification part, and the specific connection positions of the card slots and the hooks on the recovery part and the purification part are not restricted. The number and placement positions of the detachable devices can be flexibly set according to actual needs, making the device structure more flexible.

[0049] Furthermore, the recovery part, the purification part and the liquid delivery part are connected in sequence from top to bottom;

[0050] A first sealing gasket is provided at the connection between the recovery part and the purification part;

[0051] A second sealing gasket is provided at the connection between the purification part and the liquid delivery part;

[0052] A first shallow groove is provided on the purification part at the connection with the recovery part, and the first shallow groove is used to place the first sealing gasket;

[0053] A second shallow groove is provided on the liquid delivery part at the connection with the purification part, and the second shallow groove is used for placing the second sealing gasket.

[0054] From the above description, it can be seen that sealing gaskets are arranged at the connection between the recovery part and the purification part and at the connection between the purification part and the liquid delivery part. When the recovery part or the purification part is placed through the lifting rod, it can play a buffering role and it is easy to separate the recovery part, the purification part and the liquid delivery part. Shallow grooves are respectively arranged on the purification part and the liquid delivery part for placing the sealing gaskets, so that the sealing gaskets will not fall off when the various parts are disassembled.

[0055] Furthermore, the first liquid discharge pipe includes a first three-way pipe, a first inlet and an outlet of the first three-way pipe are connected to the recovery part and the purification part, and a second inlet of the first three-way pipe is connected to the lotion pipe;

[0056] The first valve is arranged on the first three-way pipe;

[0057] The second liquid discharge pipe comprises a second three-way pipe, the inlet and the second outlet of the second three-way pipe are connected to the purification part and the liquid delivery part, and the first outlet of the second three-way pipe is connected to the second inlet of the sewage pipe;

[0058] The second valve is provided on the second three-way pipe;

[0059] The third liquid discharge pipe comprises a third three-way pipe, the inlet and the second outlet of the third three-way pipe are connected to the oil collection device and the filter, and the first outlet of the third three-way pipe is connected to the first inlet of the sewage pipe;

[0060] The third valve is arranged on the third three-way pipe;

[0061] The first valve, the second valve and the third valve are all two-way valves.

[0062] As can be seen from the above description, the control of the liquid flowing into the purification part is achieved through the three-way pipe and the two-way valve arranged on the three-way pipe. If it is used under normal circumstances, the recovery part and the purification part are connected, and the coolant recovered from the equipment is sent to the purification part for evolution. If the purification part needs to be cleaned, the connection between the recovery part and the purification part can be closed by the valve, and the connection between the lotion pipe and the purification part can be opened according to the specific situation to achieve the cleaning of the purification part; at the same time, the direction of the liquid flowing out of the oil collection device and the filter can be controlled. In normal use, the oil collection device and the filter and the filter and the liquid delivery part are connected. After the coolant passes through the oil collection device and the filter, it reaches the liquid delivery part and is then delivered to the equipment for use. When the purification part needs to be cleaned, the connection between the filter and the liquid delivery part is closed by the valve, and the liquid flowing out of the filter is guided to the second inlet of the drain pipe. When cleaning the oil collection device, the connection between the oil collection device and the filter can be closed by the valve, and the waste liquid after cleaning the oil collection device is guided to the first inlet of the drain pipe without passing through the filter.

[0063] Furthermore, the liquid delivery portion includes a liquid discharge port and a liquid level sensor;

[0064] The liquid discharge port is arranged at the bottom of the liquid delivery part, and the liquid discharge port is connected to the third inlet of the sewage discharge pipe;

[0065] The liquid level sensor is arranged at the bottom of the inner wall of the liquid delivery part, and the highest point of the liquid level sensor is higher than the lowest point of the liquid outlet pipe.

[0066] From the above description, it can be seen that a drain port is provided at the bottom of the liquid delivery part. When the liquid delivery part needs to be inspected or cleaned, the liquid in the liquid delivery part can be discharged through the drain port, and a liquid level sensor is provided at different positions of the bottom of the inner wall of the liquid delivery part and the drain port. The highest point of the liquid level sensor is higher than the lowest point of the liquid outlet pipe. The liquid level sensor can give a reminder when the liquid level reaches a certain height according to the set liquid level threshold, and control the liquid replenishing pipe to replenish the liquid, thereby ensuring that one end of the liquid outlet pipe located in the liquid delivery part can always contact the coolant, thereby continuously delivering coolant to the equipment.
