Description

Technical Field

[0001] This utility model relates to the field of cutting fluid production technology, and in particular to an additive adding device for cutting fluid production. Background Technology

[0002] Cutting fluids are typically formulated from base oil or water and various additives. They are indispensable functional additives in metal cutting, grinding, and other machining processes. Generally, a certain amount of base oil is added to a reaction vessel, and then various additives are gradually added and heated to mix and react. These additives include preservatives, emulsifiers, and defoamers. To ensure the overall performance of the cutting fluid, the rational addition of various additives is crucial.

[0003] However, different additives have certain requirements for the temperature at which they are added, based on their own physicochemical properties. For example, when the temperature exceeds 50°C, the active ingredients of preservatives will decompose and become ineffective rapidly. When emulsifiers undergo emulsification reactions, the temperature needs to be controlled at 70°C to form a stable emulsion system. However, in the existing technology, various additives are added directly to the reactor in sequence, making it difficult to add different additives in a timely manner according to the different temperatures in the reactor. At the same time, most additives are in powder form. If additives are added to the base oil in a concentrated manner, they are prone to clumping and are difficult to mix evenly with the base oil, which makes it difficult to meet the needs of high-quality cutting fluid production.

[0004] Therefore, based on the above situation, it is necessary to design an additive addition device for cutting fluid production to solve the above problems. Utility Model Content

[0005] This invention provides an additive addition device for cutting fluid production to solve the problems in the prior art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] An additive addition device for cutting fluid production includes a reaction vessel with a stirring shaft inside for stirring materials within the vessel. It also includes an additive supply component, a dispersion chamber, and a discharge component. The additive supply component includes multiple containers for holding different additives, with the output end of each container connected to a conveying pipe. A valve is installed on the conveying pipe. The input and output ends of the dispersion chamber are connected to the output end of the conveying pipe and the input end of the reaction vessel, respectively. The dispersion chamber includes a sieving component for dispersing the additives conveyed from the conveying pipe. The discharge component controls the opening of valves corresponding to different containers at different temperatures, thereby enabling the addition of different additives.

[0008] Preferably, the sieving assembly includes a screen box slidably connected inside the dispersion chamber and a cam located at the bottom of the screen box and connected to the stirring shaft, and a spring connecting the screen box and the dispersion chamber.

[0009] Preferably, the inside of the screen box has an arched portion at the position corresponding to the cam.

[0010] Preferably, the discharge assembly includes a controller and a temperature sensor located inside the reactor, wherein the temperature sensor and the valve are electrically connected to the controller.

[0011] Preferably, the feed pipe is equipped with a flow meter, and the flow meter is electrically connected to the controller.

[0012] Preferably, the upper end of the screen box is provided with an elastic flared part that is in contact with the inner top surface of the dispersion chamber.

[0013] The beneficial effects of this invention are as follows: during the reaction process in the reactor, the internal temperature range gradually changes, and the discharge component releases the additives in the container at the corresponding temperature at different temperatures, maximizing the function of each additive. At the same time, the additives first fall into the dispersion chamber and are screened by the screening component. When the additives enter the reactor, they enter in a fine and dispersed state, which also reduces the situation where additive clumps cause difficulty in mixing. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0023] Reference Figures 1-6 As shown, an additive addition device for cutting fluid production includes a reaction vessel 1. The reaction vessel 1 is a container used to mix base fluids, such as base oil or water, with various additives during use. To facilitate the mixing of various substances, a stirring shaft 2 is provided inside the reaction vessel 1. Typically, a spiral stirring blade or stirring rod can be installed on the stirring shaft 2 to improve the mixing efficiency. After the additives enter the reaction vessel 1, the driving component at the bottom of the reaction vessel 1, such as a motor, drives the stirring shaft 2 to rotate through a coupling, which fully stirs the mixture in the reaction vessel 1. To accelerate the mixing reaction, a temperature control device (not shown in the figure) is also installed on the reaction vessel 1. Generally, a circulating heating medium or a circulating cooling medium is introduced into the jacket of the reaction vessel 1 to achieve temperature control of the reaction vessel 1. The above is the prior art and will not be described in detail here.

[0024] To facilitate the containment of different additives, an additive supply component is also included. This component comprises multiple container cylinders 3 for holding different additives, each with a feed pipe 4 connected to its output end. The feed pipe 4 is equipped with a valve 5. For example, three container cylinders 3 can be provided, each containing a preservative, emulsifier, and defoaming additive, respectively. As the temperature of the reaction vessel 1 gradually increases, a discharge component 8 is also provided to transport the preservative. This discharge component 8 monitors the temperature in the reaction vessel 1. For example, if the temperature is below 50°C, preservative can be added. In this case, the discharge component 8 controls the valve 5 corresponding to the container cylinder 3 containing the preservative to open, allowing the preservative to be added. When the reaction temperature in the reaction vessel 1 is around 70°C, the valve 5 corresponding to the container cylinder 3 containing the emulsifier can be opened, allowing the emulsifier to be added. When the reaction temperature in reactor 1 is around 80°C, valve 5 corresponding to the container 3 containing defoaming additives can be opened to add the defoaming additives, thereby improving the functionality of different additives. However, since most additives are in powder form, directly adding the powder into reactor 1 will cause the additives to clump together. In order to improve the uniformity of mixing with the base liquid, a dispersion chamber 6 is set between the additive supply component and reactor 1. The input and output ends of the dispersion chamber 6 are connected to the output end of the feed pipe 4 and the input end of the reactor 1, respectively. When the additives output from the feed pipe 4 enter the dispersion chamber 6, they will be screened by the screening component 7 in the dispersion chamber 6. During the screening process, the already clumped additives are broken up under the action of vibration, which can screen the additives into a finer and more dispersed state and gradually enter the reactor 1, reducing the occurrence of agglomeration when adding additives.

[0025] Reference Figures 3-6 As shown, further, in order to achieve the sieving of additives, the sieving assembly 7 includes a screen box 71 connected inside the dispersion chamber 6 and a cam 72 located at the bottom of the screen box 71 and connected to the stirring shaft 2. The bottom of the screen box 71 is a perforated screen, and the size of the pores is determined according to the particle size of the additives, generally within 200μm. During the process of adding additives to the reactor 1, the stirring shaft 2 inside the reactor 1 is constantly stirring and mixing. At the same time, the stirring shaft 2 drives the cam 72 to rotate continuously. The rotating cam 72 will continuously push against the screen box 71 and move left and right to sieve the additives. In order to improve the vibration efficiency of the screen box 71, a spring 9 is connected between the screen box 71 and the dispersion chamber 6. The spring 9 is compressed when the cam 72 pushes up the screen box 71 and stores elastic potential energy. When the cam 72 rotates away, the spring 9 releases energy and pulls the screen box 71 back quickly, forming a vibration return stroke to ensure that the sieving process is continuous.

[0026] To prevent the additives output from the feed pipe 4 from remaining inside the screen box 71, an arched portion 10 is provided inside the screen box 71 at a position corresponding to the cam 72. Since the cam 72 needs to push the screen box 71 to vibrate, the cam 72 is actually set inside the groove at the bottom of the screen box 71. To prevent the additives from falling onto the cam 72 and accumulating, no screen holes are provided at the bottom of the screen box 71 corresponding to the position of the cam 72. In order to ensure that the additives fall accurately into the screen box 71, the output ends of the feed pipes 4, which are connected to multiple receiving cylinders 3, are gathered together and located in the middle of the screen box 71. When the additives are input into the screen box 71, due to the setting of the arched portion 10, the additives are dispersed to all sides along the arched portion 10 and can be screened out through the screen holes on the screen box 71, avoiding the accumulation of additives.

[0027] Reference Figure 3 As shown, in order to add different additives at different temperatures, the discharge assembly 8 includes a controller 81 and a temperature sensor 82 located inside the reactor 1. The temperature sensor 82 and the valve 5 are both electrically connected to the controller 81. When the temperature sensor 82 detects a temperature change in the reactor 1, it transmits a signal to the controller 81, and the controller 81 controls the valve 5 to open and release the additives.

[0028] Reference Figure 2 , Figure 5 As shown, furthermore, in order to accurately control the amount of additives added, a flow meter 11 is provided on the conveying pipe 4. The flow meter 11 is electrically connected to the controller 81. The flow meter 11 is existing technology. The total amount of each additive is set by the controller 81. The flow meter 11 can monitor the instantaneous flow rate and cumulative flow rate of the additives in the conveying pipe 4 in real time and transmit the signal to the interface of the controller 81. When the conveying amount reaches the addition amount, the controller 81 receives the signal from the flow meter 11 and controls the valve 5 to close, thereby realizing the quantitative addition of the additives.

[0029] Reference Figure 6 As shown, furthermore, in order to prevent the additive from entering the dispersion chamber 6 through the gap between the top of the screen box 71 and the dispersion chamber 6, the upper end of the screen box 71 is provided with an elastic flared part 12 that is in contact with the inner top surface of the dispersion chamber 6. The elastic flared part 12 can be made of rubber, silicone or other materials. When the additive is delivered into the dispersion chamber 6, it will fall into the screen box 71 along the inclined surface of the inner wall of the elastic flared part 12. During the left and right vibration of the screen box 71, the elastic flared part 12 and the dispersion chamber 6 remain in contact to prevent the additive from escaping.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
