Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment equipment, in particular to a heat treatment liquid circulation filtering equipment with low use cost. Background Art

[0002] At present, due to the improvement of the efficiency and quality requirements of circulating fluid in heat treatment process, circulating fluid plays a key role as a cooling medium in the heat treatment of mechanical parts such as bearing rings during heat treatment. However, with the continuous use of circulating fluid, various impurities such as oil, scum and particulate matter will be mixed into it. These impurities will not only affect the cooling effect of the circulating fluid, but may also have a negative impact on the stability of the heat treatment process and product quality.

[0003] The authorization announcement number in the prior art is: CN212426115U, and the name is a coolant circulation device for heat treatment quenching, which includes a cooling device, a recovery device and a circulation device. The main body of the cooling device is a cooling trough, which contains coolant for cooling the workpieces in the workpiece basket. Lifting and sliding devices are arranged on both sides of the cooling trough. Through the telescopic rod and the mounting plate, the top slide rail is matched to realize the convenient lifting and sliding of the workpiece basket. The left and right sides of the workpiece basket are fixed with connecting plates. The slide groove on the connecting plate cooperates with the slide rail so that the workpiece basket can slide smoothly above the cooling trough. The upper part of the cooling tank is provided with a circulation discharge inlet, and the lower part is provided with a circulation discharge outlet, which are connected by a circulation pipe, and a valve is installed on the circulation pipe to control the circulation flow of the coolant. The function of the circulation device is to filter and recycle the coolant. During the circulation process, the coolant passes through the filtering device to remove impurities therein to ensure the cleanliness of the coolant, and then returns to the cooling tank through the circulation pipe again to realize the recycling of the coolant. However, when the workpiece is cooled, usually only a part of the oil temperature will be higher. When cooling, the oil temperature will start to drop after rising at a certain point, which makes the cost higher.

[0004] The application publication number in the prior art is: CN104722130A, and the name is a filtration system for heat treatment coolant, a coolant filtrate recovery pump body, a box body, a pipeline, a circulation device, a cooling device and an outlet pipe. The design of this system is to effectively filter and recover the coolant to maximize the utilization of resources. The coolant filtrate recovery pump body is the core part of the system, which is responsible for recovering and reusing the used coolant. The box body is wrapped around the outside of the pump body to play a protective and supporting role. The pipeline connects the box body and the cooling device to form a flow channel for the coolant. The circulation device is installed on the pipeline to ensure that the coolant can circulate and continuously filter and cool down. The cooling device is installed on the outside of the outlet pipe and is responsible for cooling the coolant to ensure that the coolant can maintain an appropriate temperature during the circulation process. However, when the coolant is used, there will be residues of metal workpieces, which will affect the subsequent use of the coolant and easily cause blockage. Utility Model Content

[0022] See also Figure 3 A push rod 14 is slidably mounted inside the filter box 10, the top of the push rod 14 is inclined, a stopper 15 is arranged on the push rod 14, and a push block 17 is fixedly connected to the bottom of the push rod 14 by bolts. By setting structures such as the motor 4 and the stirring rod 6, the stirring rod 6 is driven by the motor 4 to rotate, so that the oil inside the tank body 1 is in a moving state. When the workpiece is cooled, the oil will not be cooled when the temperature of part of the oil rises, thereby saving costs.

[0023] See also Figure 1-3One side of one of the support rods 5 is fixedly connected with an inclined block 8 by bolts, and the inclined block 8 is located at the top of the push rod 14. The bottom of the tank body 1 is fixedly connected with four symmetrically arranged supporting feet by bolts.

[0024] The specific implementation process of the utility model is as follows: during heat treatment, the workpiece is usually placed directly into the oil for cooling, so that the residue on the surface of the workpiece is easy to fall off inside the oil. Therefore, the motor 4 and the liquid pump 9 can be turned on at the same time, and the output end of the motor 4 drives the stirring rod 6 to rotate, and the half gear rotates at the same time, so that the half gear drives the movable frame 7 to reciprocate, and the inclined block 8 on one side of the movable frame 7 reciprocates at the same time. When the liquid pump 9 draws the oil into the interior of the filter box 10, the coarse filter 18 is first filtered to remove large pieces of residue. In the process, since the bottom of the stopper 15 is provided with a spring 16, when the inclined block 8 pushes When the push rod 14 is pushed, the push rod 14 will move downward, and when the inclined block 8 is reset with the support rod 5, due to the action of the spring 16 and the stopper 15, the push rod 14 will also rebound upward, so that the push rod 14 can drive the push block 17 to move back and forth, thereby knocking the coarse filter screen 18, and the residue on the coarse filter screen 18 slides to one side and slides out to the outside through the material channel 12. Then, a fine filter screen 19 is provided at the bottom of the filter box 10 for secondary filtering, so that the filtering effect is better, the use effect of the oil is also better, and it is not easy to cause clogging. After the filtration is completed, it is drawn into the interior of the tank body 1 through the reflux pipe 13 for recycling;

[0025] Furthermore, during use, since the workpiece will not move during cooling, the temperature of the oil will only rise at a certain point, and when the temperature at that point rises to a certain level, the circulating cooling pipe 2 will be cooled, which increases the cost. Therefore, when the motor 4 rotates, the stirring rod 6 stirs the oil accordingly, so that the oil is in a moving state, and the internal oil temperature is the same, cooling is more convenient, and the cost is reduced.
