Description

Technical Field

[0001] The invention relates to the field of bearing steel ball production, and in particular to a treatment process and a device for treating acidic and corrosive substances in a photoelectric medium of a bearing steel ball. Background Art

[0002] The production process of bearing steel balls is quite complicated. After the GCr15 bearing steel wire is cold-forged into a ball blank, it must go through processes such as polishing, soft grinding heat treatment, hard grinding, primary grinding, fine grinding, and finished product cleaning. The grinding processing of the finished steel ball is basically completed. However, the steel ball will inevitably have surface defects such as black skin and scratches during the grinding process. It is necessary to use a red-line photoelectric sorting machine to perform photoelectric detection on the steel balls and sort out the defective steel balls. During the operation of the photoelectric sorting machine, in order to prevent unnecessary secondary damage to the surface of the steel ball, such as secondary scratches, bumps, etc., photoelectric media must be used throughout the process, such as aviation kerosene, hydrocarbons, etc.

[0003] One of the core components of the steel ball photoelectric sorting machine is a nylon plate with honeycomb-shaped ball holes all around its circumference. After working continuously for a week, a layer of dirt will adhere to its surface. If the plate is not cleaned in time, the working efficiency of the photoelectric sorting machine will be greatly reduced, because the stains adhering to the plate will cause misjudgment of the photoelectric system.

[0004] At present, most of the methods for removing stains on the disk are to use acidic liquids such as dilute hydrochloric acid to remove them. Since the disk has many honeycomb-shaped balls, it is inevitable that the acidic substances in the disk cleaning liquid will be brought into the photoelectric medium, thus causing surface corrosion of the steel ball.

[0013] The upper side wall of the cooling tank is connected with a reflux pipe, the reflux pipe is bent to the top of the neutralization tank, and the end of the reflux pipe is connected with a drip pipe.

[0014] The neutralization tank is connected to the photoelectric medium container in the photoelectric sorting machine through an external pipe, and the connection height of the external pipe end of the neutralization tank on the photoelectric medium container is lower than the connection height of the first faucet external pipe and the photoelectric medium container.

[0015] An agitator is mounted on the neutralization tank, a stirring motor is arranged on the upper surface of the agitator, a driving end of the stirring motor passes through the agitator and is connected to a stirring rod, an external pipe is arranged on the lower side of the agitator, and the end of the external pipe extends to the top of the neutralization tank.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0031] A process for treating acidic and corrosive substances in the photoelectric medium of a bearing steel ball, the steps are as follows: Step 1: Detection and early warning. Install a pH monitor on the photoelectric medium container in the photoelectric sorting machine. The monitor can accurately detect the pH value in the photoelectric medium in real time. When the pH value in the photoelectric medium is detected to be lower than the preset normal range, it is determined that acidic substances are mixed in. At this time, the monitor immediately sends a signal to the central control system and triggers the sound and light alarm to remind the operator to deal with it in time; Step 2: Neutralize the acidic substance by injecting a saturated sodium carbonate solution into the dielectric. The saturated sodium carbonate solution is stored in a special acid- and alkali-resistant container. The saturated sodium carbonate solution is accurately injected into the photoelectric medium in a certain proportion according to the total amount of the photoelectric medium and the estimated content of the acidic substance. Step 3: Stirring, start the circulating stirring device to fully mix the saturated sodium carbonate solution with the photoelectric medium to ensure that the acidic substance and the saturated sodium carbonate solution undergo a complete neutralization reaction. The reaction formula is: , the acidic substance in this embodiment takes hydrochloric acid as an example; Step 4: Distillation. The photoelectric medium after the neutralization reaction is transported to the distillation device for purification. During the distillation, the remaining impurities in the photoelectric medium are further evaporated through precisely controlled high-temperature heating. Finally, in the condensation process, the pure photoelectric medium after distillation is condensed and collected through the cooling system to ensure that the photoelectric medium meets the standards of purity and safe use.

[0032] The present application also provides a process device for treating acidic and corrosive substances in the photoelectric medium of a bearing steel ball, see Figure 1 and Figure 2In this embodiment, the acid-corrosive substance treatment process device includes a distillation tank 100, a cooling tank 200 and a neutralization tank 300. An agitator 400 is mounted on the neutralization tank 300. A stirring motor 401 is arranged on the upper surface of the agitator 400.

The end of the external pipe 402 extends to the upper part of the neutralization tank 300. An external pipe 402 is also arranged on the side of the agitator 400. A second water pump 403 is installed on the external pipe 402, and a sodium carbonate solution circulation pipe is arranged at the input end of the second water pump 403. The neutralization tank 300 performs the acidic substance neutralization in step 2, and the distillation tank 100 performs the agitation in step 3. During the stirring and distillation in step 4, the saturation of the solution is maintained by continuously adding and dissolving excess sodium carbonate into the agitator 400. The saturated sodium carbonate solution is injected into the neutralization tank 300 through the external pipe 402. The photoelectric medium holding container in the synchronous photoelectric sorting machine also transports the photoelectric medium into the neutralization tank 300, so that the acidic substance in the photoelectric medium reacts with the saturated sodium carbonate solution in the neutralization tank 300. In this embodiment, the saturated sodium carbonate solution is injected for neutralization reaction, and then combined with the steps of stirring and distillation, the acidic and corrosive substances in the photoelectric medium can be effectively removed, the performance of the photoelectric medium can be ensured to be stable, its service life can be extended, the adverse effects of the acidic and corrosive substances on the processing of the bearing steel balls can be reduced, the product quality can be improved, and the processing technology is relatively simple.

[0033] See also Figure 3 and Figure 4 The distillation tank 100 in this embodiment is a double-layer structure, and a heating wire is built in the interlayer, which can provide heat for the distillation process and meet the needs of separating substances with different boiling points. A driver 1011 is installed at the bottom of the distillation tank 100. The driving end of the driver 1011 passes through the bottom of the distillation tank 100 and is connected to the stirrer 101. The driver 1011 installed at the bottom drives the stirrer 101, which can fully mix the photoelectric medium during the distillation process, improve the distillation efficiency, and ensure the purification effect. A pipeline is provided on the lower end side of the distillation tank 100 to communicate with the neutralization tank 300, and a third water pump is provided in the middle section of the pipeline. The solution in the neutralization tank 300 is extracted by the third water pump and injected into the distillation tank 100 through the pipeline. In this embodiment, the distillation tank 100 integrates stirring and distillation functions, which can fully mix the photoelectric medium during the distillation process, improve the distillation efficiency, and ensure the purification effect. The neutralization tank 300 is connected to the distillation tank 100 through a pipeline and a water pump, and the solution after the neutralization reaction can be conveniently transported to the distillation tank for further processing.

[0034] See also Figure 1 and Figure 2In this embodiment, a sealing cover 102 is installed at the upper end of the distillation tank 100. A plurality of pressure gauges 1021 are installed on the sealing cover 102, which can monitor the pressure in the distillation tank 100 in real time to ensure that the distillation process is carried out within a safe pressure range. A pipeline pressure connector 1022 is provided at the center of the upper surface of the sealing cover 102. The pipeline pressure connector 1022 is connected to a connecting pipe 2012, so that the pressure in the tank will be pushed up by the air pressure only when it reaches a certain value, so that steam enters the connecting pipe 2012. A detector 2013 is installed on the connecting pipe 2012. The detector 2013 can detect the substances coming out of the distillation tank 100, for example, whether there are still unprocessed sour and corrosive substances or other impurities, so as to adjust the processing parameters in time to ensure the quality of the photoelectric medium finally returned to the photoelectric sorting machine.

[0035] See also Figure 3 and Figure 5 In this embodiment, the end of the connecting pipe 2012 passes through the upper surface of the cooling tank 200 and extends to the inside. A spiral tube 201 is arranged in the cooling tank 200. The upper end of the spiral tube 201 is connected to the end of the connecting tube 2012 passing through the upper surface of the cooling tank 200, and the lower end of the spiral tube 201 passes through the lower end side of the cooling tank 200 and is connected to a first faucet 2011. The external pipeline of the first faucet 2011 is connected to the photoelectric medium holding container in the photoelectric sorting machine. In this embodiment, the design of the spiral tube 201 in the cooling tank 200 can increase the cooling area and improve the cooling efficiency. The photoelectric medium that has been distilled is cooled by the cooling tank 200 so that it can return to the photoelectric medium holding container of the photoelectric sorting machine at a suitable temperature to avoid the high temperature from affecting the photoelectric sorting machine and subsequent production processes. The first faucet 2011 can control the speed at which the photoelectric medium flows back to the photoelectric medium holding container.

[0036] See also Figure 1 and Figure 2In this embodiment, an input pipe 2021 is provided on the side of the cooling tank 200, and the end of the input pipe 2021 is connected to the first water pump 202, and the input end of the first water pump 202 is connected to the output pipe 2022, and the other end of the output pipe 2022 is connected to the lower end side of the neutralization tank 300 and extends to the inside, and one end of the output pipe 2022 runs through the neutralization tank 300 and is sleeved with a filter head. In this embodiment, the solution in the neutralization tank 300 is pumped into the cooling tank 200 by the first water pump 202, and the purified steam in the spiral tube 201 is quickly cooled to form liquid. The upper side wall of the cooling tank 200 is connected with a reflux pipe 203, and the reflux pipe 203 is bent to the top of the neutralization tank 300, and the end of the reflux pipe 203 is connected to a drip pipe 2031, and the solution after absorbing heat re-enters the neutralization tank 300 through the reflux pipe 203 to achieve the purpose of circulation. The drip tube 2031 serves to assist mixing to a certain extent. Since the photoelectric medium drawn out from the neutralization tank 300 for cooling the spiral tube 201 contains acidic substances and a saturated solution of sodium carbonate, the dripping of the drip tube 2031 causes the solutions to collide and achieve sufficient mixing. Furthermore, the neutralization tank 300 is connected to the photoelectric medium holding container in the photoelectric sorting machine through an external pipeline, so that the photoelectric medium containing acidic substances can enter the neutralization tank 300 for neutralization preparation, and the connection height of the external pipeline end of the neutralization tank 300 on the photoelectric medium holding container is lower than the connection height of the external pipeline of the first faucet 2011 and the photoelectric medium holding container, thereby preventing the purified solution from being sucked into the neutralization tank 300 for the second time, resulting in insufficient renewal of the photoelectric medium in the photoelectric medium holding container.
