Description

Technical Field

[0001] This utility model relates to the technical field of cutting fluid purification and treatment equipment, and specifically to a cutting fluid purification and dosing mechanism. Background Technology

[0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate cutting tools and workpieces. It is scientifically formulated with various high-performance additives, possessing excellent cooling, lubrication, rust prevention, degreasing and cleaning, corrosion prevention, and easy dilution properties. It overcomes the problems of traditional soap-based emulsions, such as easy odor in summer, difficulty in dilution in winter, and poor rust prevention. It also has no adverse effects on lathe paint and is suitable for cutting and grinding ferrous metals, making it a leading grinding product. Due to its high performance and relatively high cost, companies generally purify and recycle cutting fluids. During the purification and recycling process, waste cutting fluid contains organic components that easily breed bacteria, fungi, and other microorganisms. These microorganisms can cause the cutting fluid to smell, separate, and experience reduced lubrication. Therefore, it is necessary to add appropriate chemical reagents (such as bactericides) to the waste cutting fluid during purification to kill or inhibit these microorganisms, thereby preventing spoilage, odor, and extending its service life. Most of the chemicals added to waste cutting fluid need to be prepared and used immediately. Existing dosing systems typically involve placing two chemicals separately in a mixing tank, which is then used to add the chemicals to the waste cutting fluid. This process often leads to uneven mixing of the chemicals in the mixing tank, resulting in the added chemicals failing to achieve their intended effect and causing waste. Utility Model Content

[0003] To address the technical problem of uneven mixing of various agents in the mixing tank of existing dosing devices, this utility model provides a cutting fluid purification and dosing mechanism.

[0004] This utility model is achieved using the following technical solution: a cutting fluid purification and dosing mechanism, comprising a mixing tank, multiple raw material tanks, and multiple sets of conveying mechanisms. The multiple raw material tanks are used to store different types of raw materials. The multiple sets of conveying mechanisms are used to convey the raw materials from each raw material tank to the mixing tank for mixing. The mixing tank includes a tank body and multiple feed pipes evenly distributed circumferentially along the tank body and arranged in a rotationally symmetrical manner. The feed pipes have a J-shaped structure and include a straight pipe section, a connecting pipe section, and an inclined pipe section. The two ends of the connecting pipe section are respectively connected to the straight pipe section and the inclined pipe section. The inclined pipe section is inclined upwards from the end of the connecting pipe section away from the straight pipe section. The feed pipes are vertically arranged, and their connecting pipe section is close to the bottom of the tank body. The liquid outlet paths of the multiple feed pipes converge at the outlet of the feed pipe end. Each feed pipe is equipped with a back pressure valve, which is used to spray the raw materials conveyed by the conveying mechanism along the feed pipe into the mixing tank for mixing.

[0005] As a further improvement of this utility model, the angle between the inclined pipe section and the vertical direction is 30°-45°, and the ends of multiple inclined pipe sections away from the connecting pipe section abut against each other.

[0006] As a further improvement of this utility model, the conveying mechanism includes a metering pump, with a back pressure valve and a raw material tank connected to its two ends respectively. The metering pump is used to convey the raw materials in the raw material tank to the feed pipe.

[0007] In a typical technical solution of this utility model, the cutting fluid purification and dosing mechanism further includes a hollow outer shell, a mixing tank is fixedly installed on the side wall of the outer shell, and multiple raw material tanks are placed at the bottom of the outer shell and are all located below the mixing tank.

[0008] As a further improvement of this utility model, the mixing tank is also provided with a liquid outlet, and a check valve is installed at the liquid outlet. The check valve is used to control the mixed medicine in the mixing tank to be discharged unidirectionally from the liquid outlet.

[0009] As a further improvement of this utility model, a closed top plate with a vent is installed on the top of the outer shell. The vent is used to connect to the exhaust system and to discharge the gas generated in the mixing chamber.

[0010] The outer casing is a cuboid structure with an openable door for opening and closing. An observation window is provided on the door for observing the mixing state of the reagents inside the mixing chamber.

[0013] As a further improvement of this utility model, the outer shell is made of PP material.

[0014] The technical solution provided by this utility model has the following beneficial effects:

[0015] (1) This utility model provides a cutting fluid purification and dosing mechanism, which uses multiple feed pipes evenly distributed along the circumferential direction of a mixing tank. The outlets of the multiple feed pipes are all located at the bottom of the tank, and the liquid outlet paths of the multiple feed pipes can converge at the outlets at the ends of the feed pipes, so that the raw materials transported through the multiple feed pipes can converge above the outlets of the multiple inclined pipe sections to achieve preliminary mixing. As the feed pipes transport raw materials into the mixing tank, the liquid level in the mixing tank will gradually rise. At this time, the raw materials sprayed from the ends of the multiple feed pipes will form a vortex in the mixing tank, thereby achieving the purpose of stirring and mixing the liquid in the mixing tank. This embodiment, by designing multiple feed pipes, can not only transport various different raw materials into the mixing tank, but also enable the raw materials entering the mixing tank to be fully mixed without any stirring device.

[0016] (2) This utility model provides a cutting fluid purification and dosing mechanism, which can effectively prevent the gas generated in the mixing tank from flowing back into the raw material tank through the feed pipe and contaminating the raw material in the raw material tank by setting the feed pipe to a J-shaped structure.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] This embodiment provides a cutting fluid purification and dosing mechanism. Please refer to [reference needed]. Figure 1 and Figure 2 It includes a mixing tank, multiple raw material tanks 1, and multiple sets of conveying mechanisms. The multiple raw material tanks 1 are used to store different types of raw materials. The number of conveying mechanisms is the same as the number of raw material tanks 1; one end of each conveying mechanism is connected to a raw material tank 1, and the other end is connected to the mixing tank. The multiple sets of conveying mechanisms can transport the raw materials from the multiple raw material tanks 1 to the mixing tank for mixing. The mixing tank includes a tank body 31 and multiple feed pipes 32 that are evenly distributed circumferentially along the tank body 31 and arranged in a rotationally symmetrical manner. The feed pipes 32 have a J-shaped structure; please refer to [reference needed]. Figure 3 and Figure 4 The feed pipe 32 includes a straight pipe section 321, a connecting pipe section 322, and an inclined pipe section 323. The two ends of the connecting pipe section 322 are connected to the straight pipe section 321 and the inclined pipe section 323, respectively. The inclined pipe section 323 is inclined upwards from the end of the connecting pipe section 322 away from the straight pipe section 321. By providing the connecting pipe and the inclined pipe section 323, and by setting the inclined pipe section 323 to be inclined upwards, it is possible to prevent the gas generated in the reaction from flowing back into the raw material tank 1 through the feed pipe 32 and contaminating the raw materials in the raw material tank 1. The feed pipe 32 is vertically arranged inside the tank body 31, and the connecting pipe section 322 is located near the bottom of the tank body 31. The liquid outlet paths of multiple feed pipes 32 converge at the outlet of the end of the feed pipe 32. Each feed pipe 32 is equipped with a back pressure valve 33, which is used to regulate the pressure entering the feed pipe 32 and maintain a relatively stable pressure, thereby spraying the raw materials conveyed by the conveying mechanism along the feed pipe 32 into the mixing tank for mixing. When chemical dosing is required in the waste cutting fluid purification device, the raw materials in multiple raw material tanks 1 can be conveyed to the mixing tank through multiple sets of conveying mechanisms via the back pressure valve 33 and the feed pipes 32. The various raw materials entering the mixing tank will first converge at the outlet of the end of the feed pipe 32, thereby achieving preliminary mixing. As the liquid level in the mixing tank rises, the raw materials sprayed from the ends of the multiple feed pipes 32 will form a vortex in the mixing tank, thereby achieving the purpose of stirring and mixing the liquid in the mixing tank. This embodiment designs multiple feed pipes 32, which not only enable the delivery of various raw materials into the mixing chamber, but also allow the raw materials entering the mixing chamber to be fully mixed without any stirring device.

[0024] The angle between the inclined tube section 323 and the vertical direction can be 30°-45°, and the ends of multiple inclined tube sections 323 away from the connecting pipe abut against each other. This design allows the raw materials sprayed from multiple inclined tube sections 323 to fully contact and mix above them, thereby achieving the purpose of preliminary mixing of multiple raw materials and improving the mixing effect of the mixing box.

[0025] Please refer to Figure 1 and Figure 2 The conveying mechanism includes pipes and metering pumps 2. The pipes connect the raw material tank 1 and the back pressure valve 33. The metering pump 2 is installed on the pipes and is used to sequentially convey the raw materials in the raw material tank 1 to the mixing tank through the pipes and the feed pipe 32. The metering pump 2 can also pump out raw materials from the raw material tank 1 and convey them to the mixing tank in a quantitative manner. By using multiple metering pumps 2 to pump out different raw materials from different raw material tanks 1, the proportion of different raw materials when mixed in the mixing tank can be controlled, thereby improving the purification effect of the mixed agent on the waste cutting fluid.

[0026] Please refer to Figure 3 and Figure 4 The mixing tank can be a cuboid structure. A liquid outlet 34 is provided on the top plate of the mixing tank. The liquid outlet 34 can be connected to a waste cutting fluid purification device via a pipe. The uniformly mixed agent in the mixing tank can be transported to the waste cutting fluid purification device through the liquid outlet 34. A check valve is also installed at the liquid outlet 34 to control that the mixed agent in the mixing tank can only be discharged from the mixing tank in one direction.

[0027] The bottom of the mixing tank is also equipped with a drain port 35, which is used to drain the liquid in the mixing tank when cleaning is required. A level gauge is also installed in the raw material tank 1 to monitor the liquid level in the raw material tank 1.

[0028] The cutting fluid purification and dosing mechanism may also include an outer casing 4, which may be a cuboid structure. An openable door is mounted on the outer casing 4 for opening and closing. A mixing tank is mounted on the side wall of the outer casing 4 opposite to the door. A baffle is also mounted on the outer casing 4, positioned horizontally. Raw material tanks 1 are placed at the bottom of the outer casing 4, below the baffle, and metering pumps 2 are mounted on the baffle. An observation window may also be provided on the door, facing the mixing tank. The mixing tank may be made of transparent material, allowing operators to observe the mixing state of the chemicals inside through the observation window.

[0029] The top of the outer casing 4 is fitted with a closed top plate with ventilation openings. These openings connect to an exhaust system, allowing gases (such as harmful gases) generated within the mixing chamber to be promptly exhausted through the exhaust system, preventing them from being directly released into the air. The outer casing 4 can be made of PP material. A corrosion-resistant coating can be applied to the surface of the outer casing 4 to prevent the leakage of harmful or corrosive gases produced during the reaction, which could cause corrosion to other equipment.

[0030] The bottom of the outer shell 4 may also be provided with a drain port, which can be used to discharge any liquid remaining inside the outer shell 4 or liquid generated during cleaning of the outer shell 4.

[0031] In this embodiment, the number of raw material boxes 1 can preferably be two, please refer to... Figure 1 and Figure 2 Two raw material tanks 1 are symmetrically arranged below the mixing tank along the vertical direction of the tank body 31. Preferably, there are two feed pipes 32, each connected to one of the raw material tanks 1 via a conveying mechanism. The two feed pipes 32 are symmetrically arranged vertically within the mixing tank, with their inclined sections 323 abutting against each other, resulting in opposite outlets. The raw materials discharged from the feed pipes 32 mix at the intersection of the liquid outlet paths of the two inclined sections 323. This arrangement ensures sufficient contact between the two raw materials, thereby improving the mixing effect.

[0032] It is understood that the dosing mechanism in this embodiment is suitable for adding agents that require activation reactions upon reuse. For example, it can be used to generate bactericides through online reactions and then add them to cutting fluids for sterilization and deodorization. It can also be used for sterilization and disinfection in small-scale drinking water purification systems. It is particularly suitable for use on vehicles or other mobile platforms.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
