Description

Technical Field

[0001] The utility model relates to the technical field of workpiece quenching and cleaning, and specifically to a quenching agent cleaning system. Background Art

[0002] In current industrial production practices, quenching plays a vital role, especially in the process of heat treatment of metal workpieces to improve their mechanical properties. Through quenching, the workpiece can be cooled quickly after high-temperature heating, thereby significantly enhancing its hardness, strength, plasticity and toughness, or improving key performance indicators such as wear resistance. However, after quenching, the surface of the workpiece often adheres to a layer of quenching liquid, which is a special medium used to achieve rapid cooling, such as water, oil, polymer solution, etc. In order to ensure the cleanliness of the workpiece surface and meet the requirements of subsequent processing or use, these workpieces are usually sent to the cleaning tank for thorough cleaning.

[0003] As the cleaning operation continues, the concentration of the quenching liquid in the cleaning pool will gradually increase due to continuous accumulation. When its concentration is too high, not only will the cleaning effect be greatly reduced and the surface quality of the workpiece be affected, but it may also have an adverse effect on subsequent anti-corrosion treatments and coating processes. Therefore, traditional cleaning equipment usually needs to replace new water at a predetermined time period to maintain the concentration of the liquid in the cleaning pool within an appropriate range. The replaced cleaning liquid must be processed separately or directly discharged, which is not only cumbersome to operate and increase labor costs, but also causes environmental pollution and waste of quenching agents. Utility Model Content

[0004] The utility model provides a quenching agent cleaning system, which solves the problems of environmental pollution and quenching agent waste caused by the discharge of cleaning liquid in the cleaning process after the workpiece is quenched in the prior art.

The upper cavity is used to hold the cleaning liquid transported by the primary cleaning tank, and the lower cavity has a reflux outlet.

[0016] As a further technical solution,

[0017] There is a gap between the edge of the second plate and the inner wall of the steam recovery box, and the edge of the second plate has a convex edge.

[0018] As a further technical solution,

[0029] The working principle and beneficial effects of the utility model are:

[0030] In the utility model, liquid medicine recovery boxes are arranged on both sides of the quenching pool. The quenching pool is used to quench the workpieces that need to be quenched. The temperature of the quenching medicine in the quenching pool is generally between 260°C and 400°C. Water is placed in the primary cleaning pool. The quenched workpieces are placed in the primary cleaning pool for soaking and cleaning. After the quenching medicine in the water of the primary cleaning pool reaches a certain concentration, the cleaning liquid in the primary cleaning pool is transported to the liquid medicine recovery box. The primary cleaning pool is supplemented with low-concentration cleaning liquid or clean water. Because the liquid medicine recovery box is arranged next to the quenching pool, the temperature in the liquid medicine recovery box is higher than 100°C. The water in the cleaning liquid entering the liquid recovery box evaporates at high temperature and is discharged through the steam outlet, and the remaining quenching agent is discharged from the quenching agent outlet, thereby achieving the purpose of cleaning the workpiece after quenching, and the quenching agent in the cleaning liquid can be recovered. At the same time, the recovered quenching agent can be added to the quenching pool. In the whole process, only water is discharged by evaporation, which will not pollute the environment, and there is no need to separately deal with the high-concentration cleaning liquid containing quenching agent, which reduces labor costs. The setting of the other two liquid recovery boxes can cool the quenching pool, facilitate the adjustment of the temperature of the quenching pool, and also reduce the heat loss of the quenching pool.

In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0044] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0045] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0046] like Figure 1-10As shown, the utility model proposes a quenching agent cleaning system, including: a quenching pool 1, a primary cleaning pool 2, a liquid medicine recovery box 3 is arranged next to the quenching pool 1, the liquid medicine recovery box 3 is connected to the primary cleaning pool 2 through a pipeline, and the liquid medicine recovery box 3 has a steam outlet 31 and a quenching agent outlet 32.

[0047] In this embodiment, Figure 1 As shown, liquid medicine recovery boxes 3 are arranged on both sides of the quenching pool 1. The quenching pool 1 is used to quench the workpieces that need to be quenched. The temperature of the quenching medicine in the quenching pool 1 is generally between 260°C and 400°C. Water is placed in the primary cleaning pool 2. The quenched workpieces are placed in the primary cleaning pool 2 for soaking and cleaning. After the quenching medicine in the water of the primary cleaning pool 2 reaches a certain concentration, the cleaning liquid in the primary cleaning pool 2 is transported to the liquid medicine recovery box 3. Low-concentration cleaning liquid or clean water is added to the primary cleaning pool 2. Because the liquid medicine recovery box 3 is arranged next to the quenching pool 1, the temperature in the liquid medicine recovery box 3 is higher than 100°C. The water in the cleaning liquid entering the liquid recovery box 3 evaporates at high temperature and is discharged through the steam outlet 31, and the remaining quenching agent is discharged from the quenching agent outlet 32, thereby achieving the purpose of cleaning the workpiece after quenching, and the quenching agent in the cleaning liquid can be recovered. At the same time, the recovered quenching agent can be added to the quenching pool 1. In the whole process, only water is discharged by evaporation, which will not pollute the environment, and there is no need to separately deal with the high-concentration cleaning liquid containing quenching agent, thereby reducing labor costs. The setting of the other two liquid recovery boxes 3 can cool the quenching pool 1, facilitate the adjustment of the temperature of the quenching pool 1, and also reduce the heat loss of the quenching pool 1.

[0048] Furthermore, the first plate 33 is tiltedly arranged in the liquid medicine recovery box 3 , the first plate 33 has an upper end and a lower end, and there is a gap between the upper end and / or the lower end of the first plate 33 and the inner wall of the liquid medicine recovery box 3 .

[0049] In this embodiment, Figure 6 and Figure 7 As shown, when the high-concentration cleaning liquid containing quenching agent transported from the primary cleaning pool 2 enters the liquid recovery box 3, the cleaning liquid first passes through the upper end of the first plate 33 and then flows to the lower end, thereby increasing the contact area between the cleaning liquid and the hot air in the liquid recovery box 3, being more conducive to the evaporation of water in the cleaning liquid, achieving the purpose of quickly precipitating the quenching agent, and improving the recovery efficiency. The setting of the gap is conducive to the discharge of water vapor.

[0050] Furthermore, a plurality of first plates 33 are provided, and the plurality of first plates 33 are arranged in sequence from top to bottom, and the upper end of one first plate 33 is located below the lower end of another adjacent first plate 33 , and the inclined directions of the two adjacent first plates 33 are opposite.

[0051] In this embodiment, Figure 6 As shown, a plurality of first plates 33 are arranged in a serpentine shape, which increases the contact area between the cleaning liquid and the hot air, and also increases the time the cleaning liquid stays in the liquid recovery box 3, further improving the evaporation efficiency of the cleaning liquid.

[0052] Furthermore, the baffle 34 is disposed on the upper end of the first plate body 33 .

[0053] In this embodiment, Figure 6 and Figure 7 As shown, the baffle 34 can prevent the flowing cleaning liquid from being discharged from the upper end of the first plate body 33 .

[0054] Furthermore, it also includes a steam recovery box 4, a second plate 41 is arranged in the steam recovery box 4, the second plate 41 divides the interior of the steam recovery box 4 into an upper cavity 42 and a lower cavity 43, the lower cavity 43 is connected with the steam outlet 31 of the liquid recovery box 3 through a pipeline, the upper cavity 42 is connected with the primary cleaning tank 2 through a pipeline, the upper cavity 42 is used to hold the cleaning liquid transported by the primary cleaning tank 2, and the lower cavity 43 has a reflux outlet.

[0055] In this embodiment, Figure 5 As shown, the water vapor discharged from the steam outlet 31 of the medicine liquid recovery box 3 enters the steam recovery box 4 for condensation, and the condensed water is discharged into the primary cleaning pool 2 through the reflux outlet, thereby achieving the function of replenishing water. At the same time, heat exchange is completed by transporting the cleaning liquid in the primary cleaning pool 2 to the upper cavity 42. The second plate 41 divides the steam recovery box 4 into an upper cavity 42 and a lower cavity 43. The gap between the edge of the second plate 41 and the inner wall of the steam recovery box 4 can be used to pass the cleaning liquid in the primary cleaning pool 2, so that the cleaning liquid enters the lower cavity 42 and is discharged through the reflux outlet.

[0056] Furthermore, there is a gap between the edge of the second plate body 41 and the inner wall of the steam recovery box body 4 , and the edge portion of the second plate body 41 has a convex edge 44 .

[0057] In this embodiment, the convex edge 44 on the edge of the second plate body 41 is located on a horizontal plane, and the whole is equivalent to a plate. When the height of the cleaning liquid on the second plate body 41 reaches the height of the convex edge 44, the cleaning liquid will overflow through the convex edge 44, and then be transported to the lower cavity 43 through the gap. The cleaning liquid passing through the gap will block the gap to prevent water vapor from entering the upper cavity 42 from the lower cavity 43. A number of micro holes are opened on the surface of the second plate body 41. The micro holes are used for passing and dripping cleaning liquid, which not only improves the heat exchange efficiency, but also prevents the cleaning liquid from precipitating quenching agent on the second plate body 41, thereby reducing the number of times the second plate body 41 is cleaned. The micro holes are conical, and the end with a larger diameter of the micro holes faces upward, which can effectively prevent blockage.

[0058] Furthermore, the reflux outlet is connected to the primary cleaning tank 2 through a pipeline.

[0059] In this embodiment, the condensed water in the steam recovery box 4 flows back into the primary cleaning pool 2 through the reflux outlet, playing a role in replenishing water to a certain extent.

[0060] Furthermore, the steam recovery box 4 is located above the liquid medicine recovery box 3 , and a pump is provided on the pipeline connecting the upper cavity 42 and the primary cleaning tank 2 .

[0061] In this embodiment, Figure 1 As shown, the steam recovery box 4 is located at the top, which can be beneficial to the transportation of steam and the reflux of condensed water. The pump can pump the cleaning liquid in the primary cleaning pool 2 into the upper cavity 42 and can control the flow rate.

[0062] Furthermore, the secondary cleaning tank 5 and the intermediate liquid storage tank 6 are connected to the secondary cleaning tank 5 and the primary cleaning tank 2 respectively through pipelines.

[0063] In this embodiment, Figure 1 As shown, the workpiece after being cleaned in the primary cleaning tank 5 is immersed and cleaned again in the secondary cleaning tank 5, so that the surface of the workpiece is cleaner. The concentration of quenching agent in the cleaning liquid in the secondary cleaning tank 5 is lower than the concentration of quenching agent in the primary cleaning tank 2. When there is too much cleaning liquid in the secondary cleaning tank 5, it will be pumped into the intermediate liquid storage tank 6, and the cleaning liquid in the intermediate liquid storage tank 6 is used to replenish the primary cleaning tank.

[0064] Furthermore, the tertiary cleaning tank 7 is connected to the secondary cleaning tank 5 through a pipeline.

[0065] In this embodiment, the tertiary cleaning pool 7 is a spray pool, which continuously sprays the workpiece that has undergone secondary cleaning with clean water to obtain a workpiece that has been finally cleaned.

[0066] Furthermore, the primary cleaning tank 2 and the secondary cleaning tank 5 are both immersion tanks, and the tertiary cleaning tank 7 is a spray tank. After the liquid level in the tertiary cleaning tank 7 reaches a certain height, the cleaning liquid therein overflows into the secondary cleaning tank 5 through a pipeline.

[0067] In this embodiment, overall, clean water will be continuously sprayed in the tertiary cleaning tank 7 to complete the final cleaning of the workpiece. When the water in the tertiary cleaning tank 7 reaches a certain water level, it will overflow to the secondary cleaning tank 5 through the pipeline to complete the replenishment of the cleaning liquid in the secondary cleaning tank 5. When the cleaning liquid in the secondary cleaning tank 5 reaches a certain liquid level, it will be pumped out to the intermediate liquid storage tank 6, and the intermediate liquid storage tank 6 will replenish the cleaning liquid in the primary cleaning tank. From the whole process, basically only water evaporation is consumed, and the only discharged substance is the precipitated quenching agent, without any pollution, and the labor cost is greatly reduced. By controlling the rate of outputting clean water in the clean water tank 94 and the rate of cleaning liquid delivery in each link, a dynamic balance can be achieved as a whole, thereby completing the purpose of cleaning the quenching agent on the surface of the workpiece.

[0068] Furthermore, a pump is provided on the pipeline between the liquid recovery box 3 and the primary cleaning tank 2, a pump is provided on the pipeline between the primary cleaning tank 2 and the intermediate liquid storage tank 6, a pump is provided on the pipeline between the secondary cleaning tank 5 and the intermediate liquid storage tank 6, and a pump is provided on the pipeline between the secondary cleaning tank 2 and the tertiary cleaning tank 7.

[0069] In this embodiment, the pump is provided to achieve directional and rate-adjustable delivery of the cleaning liquid, thereby achieving a better circulation effect.

[0070] Furthermore, an exhaust valve 91 is provided on the steam recovery box 4 .

[0071] In this embodiment, the exhaust valve 91 is provided to exhaust the gas when the gas pressure in the steam recovery box 4 reaches a certain value, which can effectively avoid the safety problem caused by the excessive gas pressure in the steam recovery box 4.

[0072] Furthermore, it also includes that the liquid equalizing container 81 is swingably set in the liquid recovery box 3, the liquid equalizing container 81 is located above the first plate body 33, the liquid equalizing container 81 is used to receive the cleaning liquid delivered by the primary cleaning pool 2, the liquid equalizing container 81 has a liquid equalizing outlet 82, and a plurality of guide grooves 83 are arranged in parallel at the liquid equalizing outlet 82 of the liquid equalizing container 81. After the liquid equalizing container 81 is swung, it is located in a liquid equalizing state or a cleaning state. When the liquid equalizing container 81 is in the liquid equalizing state, the lowest point of the liquid in the liquid equalizing container 81 is lower than the liquid equalizing outlet 82. When the liquid equalizing container 81 is in the cleaning state, the lowest point of the liquid in the liquid equalizing container 81 is higher than the liquid equalizing outlet 82.

[0073] In this embodiment, Figure 7 , Fig. 9 and Fig.10 As shown, Figure 7The state is a uniform liquid state. The transported cleaning liquid first enters the uniform liquid container 81. When the uniform liquid container 81 is full, the cleaning liquid will be discharged through the guide groove 83 located on the same horizontal plane. The guide groove 83 is arranged along the width direction of the first plate body 33, so that the cleaning liquid discharged through the uniform liquid container 81 can cover the entire plate surface of the first plate body 33, so that the cleaning liquid has a larger contact area with the hot air and evaporates faster, which greatly improves the recovery rate of the quenching agent. Figure 8 The state shown is a cleaning state. At this time, the liquid equalizing container 81 can no longer retain the cleaning liquid. The cleaning liquid that enters at this time will flush the liquid equalizing container 81 to prevent the precipitated quenching agent from filling the entire liquid equalizing container 81, thereby improving the use stability of the liquid equalizing container 81. As long as the liquid equalizing container 81 is swung on time, the purpose of cleaning the liquid equalizing container 81 can be achieved, which is very convenient.

[0074] Furthermore, a plurality of guide grooves 83 are arranged along the width direction of the first plate body 33 , and the bottom of the liquid equalizing container 81 for storing liquid is a smooth curved surface.

[0075] In this embodiment, the bottom of the liquid equalizing container 81 for storing liquid is a smooth curved surface, and there is no dead corner left, so the liquid equalizing container 81 can be cleaned better.

[0076] Furthermore, it also includes that the shaft 84 is rotatably set in the medicine liquid recovery box 3, the liquid equalizing container 81 is swingably set on the medicine liquid recovery box 3 through the shaft 84, one end of the shaft 84 passes through the side wall of the medicine liquid recovery box 3 and extends out of it, the handle 85 is set at the end of the shaft 84 located outside the medicine liquid recovery box 3, and the limit member 86 is set on the medicine liquid recovery box 3, and the limit member 86 is used to limit the shaft 84 to be in the liquid equalizing state.

[0077] In this embodiment, Figure 3 and Fig.10 As shown, by rotating the handle 85, the shaft 84 can be driven to rotate, thereby adjusting the state of the liquid equalizing container 81, which is very convenient.

[0078] Furthermore, a limiting groove 87 is formed on the side wall of the shaft body 84 , and the limiting member 86 includes a latch 88 which is slidably disposed on the liquid medicine recovery box 3 , and the latch 88 is inserted into the limiting groove 87 after sliding.

[0079] In this embodiment, the purpose of limiting the angle of the shaft 84 is achieved by inserting the latch 88 into the limiting groove 87, thereby achieving the effect of keeping the liquid equalizing container 81 in a certain state.
