Description

Technical Field

[0001] The present application relates to the field of heat treatment, and in particular to an energy-saving fastener heat treatment device. Background Art

[0002] Heat treatment refers to a metal thermal processing process in which metal materials are heated, insulated, and cooled in solid state to change the chemical composition and structure of the material surface or internally to obtain the desired properties. Fasteners, also known as standard parts in the market, are a general term for a type of mechanical parts used to fasten two or more parts (or components) into a whole. Fasteners also need to undergo the above-mentioned heat treatment process during the production process to improve the performance of the fasteners to meet the requirements of use.

[0003] The fasteners are first washed with water, and then sent to the heat treatment furnace for heat treatment. The fasteners entering the heat treatment furnace are heated to a predetermined temperature, and then a series of heat treatment processes are carried out to complete the heat treatment of the fasteners.

[0004] Existing heat treatment equipment generally consumes a lot of energy, especially when fasteners are being heat treated. Since fasteners need to be continuously fed in and then sent out after heat treatment, heat is continuously lost in this process, increasing energy consumption. Summary of the Invention

[0005] In order to make fuller use of the thermal energy of the heat treatment equipment, the present application provides an energy-saving fastener heat treatment equipment.

[0006] The energy-saving fastener heat treatment equipment provided in this application adopts the following technical solutions:

[0007] An energy-saving fastener heat treatment equipment includes a water washing tank, a heat treatment furnace and a boiler. The boiler is installed at the entrance of the heat treatment furnace for fasteners to enter and is located above the heat treatment furnace. The heat treatment furnace includes a heat treatment conveyor belt. The water washing tank is provided with a lifting assembly for feeding the cleaned fasteners into the heat treatment conveyor belt. A baffle is provided between the boiler and the lifting assembly. The baffle is located above the heat treatment conveyor belt and is spaced from the entrance of the heat treatment furnace to guide heat upward. A water circulation pipeline is provided between the boiler and the water washing tank, and a water pump for driving the water circulation is provided on the water circulation pipeline.

[0008] By adopting the above technical solution, the fasteners are first washed with water and then enter the heat treatment furnace for heat treatment, so that the fasteners are cleaner before heat treatment. At the same time, the heat released by the heat treatment furnace is used for heating by the boiler, and then the hot water is directed to the water sink for fastener cleaning. The fasteners are pre-heated by hot water during the cleaning process, so that the fasteners have been heated to a certain extent before entering the heat treatment, thereby improving the heat treatment efficiency, making full use of thermal energy, and being more energy-efficient. The baffle set between the boiler and the lifting assembly, on the one hand, blocks the direct heating of the water washing equipment by the flame released by the heat treatment furnace, reducing damage to the equipment due to overheating, and on the other hand, it also guides the external heat to the boiler more fully, thereby improving the efficiency of waste heat utilization.

[0009] Optionally, a loading device is also included, which includes a loading pool, a rubber conveyor belt, a loading drive for driving the rubber conveyor belt, a loading bracket for installing the rubber conveyor belt and the loading drive, and a magnetic block installed in the loading bracket. The loading pool is located on the side of the rubber conveyor belt away from the water washing pool. The rubber conveyor belt passes through the loading pool, runs upward, flips over, passes through the upper opening of the water washing pool and returns to the loading pool. The magnetic block always adheres to the part of the rubber conveyor belt close to the loading pool.

[0010] By adopting the above technical solution and the magnetic feeding method, on the one hand, the rubber conveyor belt is supported by the magnetic block, making the rubber conveyor belt more stable during operation and reducing the collision of fasteners. On the other hand, the magnetic feeding method also reduces the collision and wear between the fasteners and the feeding equipment, making the fasteners less likely to wear and damage before heat treatment, thereby improving the yield rate.

[0011] Optionally, it also includes a wastewater drainage and cleaning component, which includes a drainage pipe, a cleaning sleeve and a receiving box. One end of the drainage pipe is connected to the bottom of the water washing tank, and the other end extends to the feeding device and is located at the bottom of the rubber conveyor belt. The receiving box is located below the feeding device and the water washing tank. The cleaning sleeve is installed at one end of the drainage pipe close to the rubber conveyor belt. The cleaning sleeve is provided with a long strip opening for drainage, and the long strip opening extends along the width direction of the rubber conveyor belt and covers the rubber conveyor belt.

[0012] By adopting the above technical solution, the wastewater discharge and cleaning component can discharge the water in the water washing tank after the water washing tank has been running for a period of time, thereby facilitating the replenishment of water in the water washing tank, thereby resetting the state of the water washing tank and ensuring the water washing effect. At the same time, in the process of discharging wastewater, the discharged wastewater is used to clean the rubber conveyor belt, clean the oil contaminated on the rubber conveyor belt, reduce the impact of the oil on the rubber conveyor belt on the transportation of fasteners, and regularly clean the part of the oil contaminated on the fasteners that is transferred to the rubber conveyor belt. The setting of the long strip mouth allows the water discharged from the discharge pipe to fully contact the entire rubber conveyor belt to ensure the cleaning effect.

[0013] Optionally, the wastewater drainage and cleaning assembly further includes a stirring barrel and a detergent bottle, the stirring barrel being installed on the drainage pipe, the stirring barrel being provided with a detergent filling inlet, the detergent bottle being filled with detergent and injecting detergent into the stirring barrel through the detergent filling inlet.

[0014] By adopting the above technical solution, a stirring barrel and a detergent bottle are provided. The detergent bottle is used to fill the stirring barrel with detergent, and the stirring barrel is used to stir and mix the detergent and wastewater for cleaning the rubber conveyor belt.

[0015] Optionally, the drainage pipe is provided with at least one downwardly protruding portion and a sedimentation space is formed inside. A sewage outlet is provided at the bottom of the sedimentation space and a sewage outlet cover is installed to close the sewage outlet.

[0016] By adopting the above technical solution, a sedimentation space is set up to precipitate the sediment brought out from the discharge pipe. By removing large particles of impurities as much as possible, the cleaning effect of wastewater on the rubber conveyor belt is improved, while the impact of impurities on the rubber conveyor belt is reduced.

[0017] Optionally, the wastewater discharge cleaning component also includes power blades, stirring blades and a power component associated with the power blades and the stirring blades. The power blades are installed in the discharge pipe and rotate driven by the liquid flow. The stirring blades are installed in the stirring barrel. The power blades and the stirring blades are rotated synchronously through the power component.

[0018] By adopting the above technical solution, the power fan blades not only transmit power to drive the stirring blades to rotate, but also use the potential energy of the wastewater to drive the stirring blades to mix the detergent and wastewater. At the same time, the power fan blades also play a certain role in separation and stirring, reducing the flow rate of the water flow and reducing the impact of impurity particles on the rubber conveyor belt.

[0019] Optionally, the stirring fan blade is installed at the water outlet of the stirring barrel, and the stirring fan blade is tilted upward to push the liquid to flow toward the barrel wall of the stirring barrel, and the detergent filling inlet is located in the direction of the liquid flow pushed by the stirring fan blade.

[0020] By adopting the above technical solution, on the one hand, it conforms to the direction of installation of the power component. On the other hand, if the detergent is not stirred, it will enter the drain pipe, and the subsequent power fan blades can also stir the detergent. At the same time, the stirring blades are located at the water outlet of the stirring barrel to achieve speed balance. When the water flow is large, the power fan blades accelerate, driving the stirring blades to accelerate. The rotation of the stirring blades hinders the increase of water flow, thereby reducing the acceleration of the power fan blades, achieving better dynamic balance, and controlling the water flow speed. At the same time, the stirring blades further block the entry of particulate matter, and the stirring blades push upward to create waves and bring out detergent, while not easily disturbing the precipitated particles.

[0021] Optionally, the detergent bottle is provided with a liquid outlet, the detergent bottle is installed on the mixing barrel, and the liquid outlet enters the mixing barrel through the detergent filling inlet, the liquid outlet is installed with a foaming cotton cloth, the detergent in the detergent bottle continuously soaks the foaming cotton cloth, and the foaming cotton cloth prevents the detergent in the detergent bottle from flowing out directly.

[0022] By adopting the above technical solution, the stirring blades push upward to create waves, bringing out the detergent from the foaming cotton cloth. The presence of the foaming cotton cloth better promotes the mixing of detergent and wastewater. At the same time, the foaming cotton cloth limits the speed of free outflow of detergent, thereby reducing detergent waste.

[0023] Optionally, the boiler is provided with a water supply pipe and an external water source, the water supply pipe is provided with a switch valve, the top of the water washing tank is provided with an oil drain port, the bottom of the water washing tank is provided with a sewage hole, the oil drain port is higher than the liquid level in the water washing tank, and the oil drain port is spaced 2mm-5mm from the liquid level of the washing liquid in the water washing tank.

[0024] By adopting the above technical scheme, the sewage hole set up can be used to clean the sediment at the bottom of the washing tank, ensuring the periodic recovery state of the washing tank. At the same time, after cleaning the main sediment, the wastewater discharge and cleaning component are used to utilize the wastewater, which can reduce the impact of sediment on wastewater utilization. The setting of the water supply pipe can replenish the water loss in the washing tank during the use of the equipment. At the same time, after the sediment is discharged and the wastewater is utilized, water can be quickly replenished to achieve the reset of the equipment. At the same time, the oil drain port is set, and the oil drain port is separated from the water surface in the washing tank by a certain distance, so that some surface floating oil can be discharged, reducing the oil washed from the fasteners by the washing tank, regularly cleaning the oil, and reducing the amount of oil taken away again by the fasteners when coming out of the washing tank. At the same time, a certain oil level is always maintained to keep the water in the washing tank warm and ensure the preheating effect of the water temperature on the fasteners. The oil drain port is also used as a water level line to control the amount of water replenishment.

[0025] Optionally, the oil drain port is provided with a recovery component, which includes a recovery box, a recovery ball and a collection box. The recovery box is installed in the water washing pool, the oil drain port is connected to the recovery box, an oil drain pipe is provided on the upper part of the recovery box, and a sealing cover is installed at the opening of the oil drain pipe. The collection box is provided with an inlet for inserting the oil drain pipe, the recovery ball is connected to the bottom of the recovery box and reciprocates to inject water into the recovery box, and pushes the oil in the recovery box to be discharged through the oil drain pipe.

[0026] By adopting the above technical solution, a recovery component is set at the oil drain port, and the oil is recovered by the recovery component. On the one hand, the pollution of the oil is reduced, and on the other hand, the oil can be recovered for reuse, such as for lubrication of equipment. The recovery box receives the oil that continuously overflows from the oil drain port. When the oil needs to be taken out from the recovery box, the cover is opened and the collection box is installed on the oil drain pipe to receive the oil. At the same time, water is injected into the recovery box through the recovery ball to raise the height of the oil in the recovery box, and all the oil in the recovery box is taken out as much as possible to complete the oil recovery. This recovery method ensures uninterrupted oil recovery. At the same time, the oil can be recovered at any time, and the oil is not easy to overflow and pollute.

[0027] To sum up, the fasteners are first washed with water and then enter the heat treatment furnace for heat treatment, so that the fasteners are cleaner before heat treatment. At the same time, the heat released by the heat treatment furnace is used for heating by the boiler, and then the hot water is directed to the water tank for fastener cleaning. The fasteners are pre-heated by hot water during the cleaning process, so that the fasteners have been heated to a certain extent before entering the heat treatment, thereby improving the heat treatment efficiency, making full use of thermal energy, and being more energy-efficient. The baffle set between the boiler and the lifting assembly, on the one hand, blocks the direct heating of the water washing equipment by the flame released by the heat treatment furnace, reducing damage caused by overheating of the equipment, and on the other hand, it also guides the external heat to the boiler more fully, thereby improving the efficiency of waste heat utilization.

[0037] The following is combined with Figure 1-8 This application is described in further detail.

[0038] The embodiments of the present application disclose an energy-saving fastener heat treatment device.

[0039] Reference Figure 1 and Figure 2 , an energy-saving fastener heat treatment equipment, including a feeding device 1, a water washing tank 2, a heat treatment furnace 3 and a matching wastewater drainage and cleaning component 4 and a boiler 5. The fasteners are sent into the water washing tank 2 for cleaning and preheating through the feeding device 1, and then the fasteners in the water washing tank 2 are sent into the heat treatment furnace 3 to complete the heat treatment. The boiler 5 is installed at the entrance of the heat treatment furnace 3 for the fasteners to absorb the waste heat emitted by the heat treatment furnace 3. The boiler 5 and the water washing tank 2 are connected by a water circulation pipeline to increase the water temperature in the water washing tank 2. The wastewater drainage and cleaning component 4 is used for the drainage, replacement and reuse of the washing liquid in the water washing tank 2.

[0040] The feeding device 1 includes a feeding tank 11, a rubber conveyor belt 12, a feeding driver 13 for driving the rubber conveyor belt 12, a feeding bracket 14 for installing the rubber conveyor belt 12 and the feeding driver 13, and a magnetic block installed in the feeding bracket 14. In this embodiment, the feeding bracket 14 is composed of two left and right steel plates and a plurality of steel structure columns connecting the two steel plates as a whole. The feeding driver 13 adopts a motor and a roller. There are multiple rollers. The rubber conveyor belt 12 is reversing and covers all the rollers. The output shaft of the motor is connected to one of the rollers through a chain, so that the motor drives the roller to rotate, and then the roller and the rubber conveyor belt are connected. The connecting mechanism between the conveyor belts 12 realizes the continuous operation of the rubber conveyor belt 12. The two sides of the loading pool 11 are installed on two steel plates, and the loading pool 11 is located on the side of the rubber conveyor belt 12 away from the water washing pool 2. The loading pool 11 extends upward and cantilevered on the side away from the rubber conveyor belt 12. The loading pool 11 is a shell with openings on the upper side and the side close to the rubber conveyor belt 12. The inner walls of the loading pool 11 on both sides of the rubber conveyor belt 12 are installed with guide plates 111. The distance between the two guide plates 111 is smaller the closer to the rubber conveyor belt 12, thereby guiding the fasteners in the loading pool 11 to the rubber conveyor belt 12.

[0041] At the same time, the loading pool 11 is located at the middle height of the loading bracket 14, and the middle part of the rubber conveyor belt 12 is in contact with the loading pool 11. A magnetic block is installed on the loading bracket 14. The magnetic block is located in the space surrounded by the rubber conveyor belt 12, and the magnetic block only contacts the rubber conveyor belt 12 close to the loading pool 11. The part above the loading pool 11 and the upper side wall of the rubber conveyor belt 12 are in contact with the rubber conveyor belt 12, so that the rubber conveyor belt 12 is sent to the loading pool 11 to adsorb the fasteners and carry the fasteners over the loading bracket 14 for unloading.

[0042] In this embodiment, the magnetic block may be an electromagnet, so that it is convenient to control whether to load the fasteners according to the situation, and it is also convenient to automatically control the loading process.

[0043] Reference Figure 2 and Figure 3 The water washing tank 2 is located between the heat treatment furnace 3 and the feeding equipment 1. The water washing tank 2 is a shell with an open top. The space inside the water washing tank 2 is set as a water washing space 21. The bottom of the water washing space 21 is a V-shaped space with two inclined surfaces. In order to close the opening above the water washing tank 2, reduce liquid splashing and loss, and ensure that fasteners can easily enter and exit the water washing tank 2, a closing plate 22 is installed in the middle of the top of the water washing tank 2. A first inlet shell 23 is installed on the side of the top of the water washing tank 2 close to the feeding equipment 1, and a second inlet shell 24 is installed on the side of the water washing tank 2 close to the heat treatment furnace 3. The first inlet shell 23 and the second inlet shell 24 are open on the side away from each other and the side facing downward.

[0044] A first receiving plate 6 with a channel is installed on the feeding bracket 14. The first receiving plate 6 is tilted up and down. The higher side of the first receiving plate 6 is fixed to the feeding bracket 14 and is located below the part where the rubber conveyor belt 12 passes over the highest point after passing through the feeding pool 11 to receive the fasteners that fall. The lower side of the first receiving plate 6 enters the interior of the first inlet shell 23 and is located above the water washing space 21 of the water washing pool 2, and transports the fasteners to the water washing space 21.

[0045] The heat treatment furnace 3 includes a heating furnace 31 and a heat treatment conveyor belt 32 that continuously moves in the heating furnace 31 with fasteners. The heat treatment conveyor belt 32 partially extends to the outside of the heating furnace 31. The heat treatment conveyor belt 32 is located on the bracket of the outer part of the heating furnace 31 and is equipped with a waste heat utilization rack 33 and a baffle 34. The baffle 34 is located on the side of the waste heat mounting rack away from the heating furnace 31. The waste heat utilization rack 33 is located at the entrance of the heating furnace 31 for fasteners to enter. The distance between the waste heat utilization rack 33 and the heat treatment conveyor belt 32 is sufficient for the fasteners to pass through. The flame in the heating furnace 31 passes through the space between the waste heat utilization rack 33 and the heat treatment conveyor belt 32 and hits the baffle 34. The distance between the baffle 34 and the heat treatment conveyor belt 32 is also sufficient for the fasteners to pass through.

[0046] The boiler 5 is installed on the waste heat utilization rack 33, and the water washing tank 2 is provided with a lifting assembly 25 for delivering the cleaned fasteners into the heat treatment conveyor belt 32. The bottom of the lifting assembly 25 is located at the bottom of the water washing space 21. In order to facilitate the installation of the lifting assembly 25, a lifting bracket 35 is provided on the side of the heat treatment conveyor belt 32 away from the heating furnace 31. The top of the lifting assembly 25 passes through the opening of the second inlet shell 24 and is installed on the lifting bracket 35. A motor and a reducer for driving the lifting assembly 25 are installed above the lifting bracket 35. A second receiving plate 7 is also installed on the lifting bracket 35. The second receiving plate 7 is also tilted up and down. The higher side of the second receiving plate 7 is located below the rear part of the lifting assembly 25 over the top, and the fasteners brought out from the water washing tank 2 after cleaning are received through the second receiving plate 7. The lower side of the first receiving plate 6 is located above the heat treatment conveyor belt 32 to deliver the fasteners to the heat treatment furnace 3.

[0047] A water circulation pipeline is provided between the boiler 5 and the water washing tank 2, and a water pump 51 is provided on the water circulation pipeline to drive the water circulation flow. Specifically, the water circulation pipeline includes an outlet pipe 52 and an inlet pipe 53. One end of the inlet pipe 53 is connected to the middle of the water washing tank 2, and the other end is connected to the boiler 5. The water pump 51 is installed on the inlet pipe 53. The water pump 51 continuously pumps water from the water washing tank 2 and sends it into the boiler 5. The height of the boiler 5 is higher than the water washing tank 2. The hot water in the boiler 5 continuously flows back to the water washing tank 2 under the action of gravity. One end of the outlet pipe 52 is connected to the boiler 5, and the other end is connected to the bottom of the water washing tank 2. The positions where the inlet pipe 53 and the outlet pipe 52 are connected to the water washing tank 2 are respectively located on both sides of the water washing tank 2 to ensure the water temperature at the bottom of the water washing tank 2. The water from the water washing tank 2 is sent to the boiler 5 through the inlet pipe 53, and the water in the boiler 5 is sent to the water washing tank 2 through the outlet pipe 52. The pipe portion of the water outlet pipe 52 is laid inside the waste heat utilization frame 33, thereby making full use of the waste heat.

[0048] At the same time, the top of the above-mentioned boiler 5 is open, so that when the water in the boiler 5 boils, the internal air pressure of the boiler 5 is reduced, so that when the water in the boiler 5 is overheated, the steam has a discharge outlet. At the same time, it is ensured that the liquid in the boiler 5 flows freely back to the water washing tank 2 under the action of gravity, ensuring that the flow is always smooth, which is conducive to liquid cleaning during maintenance.

[0049] The boiler 5 is also provided with a water supply pipe 54 and an external water source. The water supply pipe 54 is provided with a switch valve 55. The water supply rate of the water supply pipe 54 into the boiler 5 is close to the overall loss rate of various liquids in the water washing, and the rate at which the boiler 5 drains water into the water washing tank 2 is higher than the water pump 51 pumping water from the water washing tank 2. The difference between the two is also close to the water loss rate in the water washing tank 2. The water supply process ensures the water level in the boiler 5, thereby ensuring the drainage rate and also ensuring the water level in the water washing tank 2.

[0050] Reference Figure 4 and Figure 6 At the same time, an oil drain port 26 is provided on the top of the water washing tank 2, and a sewage hole 27 is provided at the bottom of the water washing tank 2. The oil drain port 26 is located on the side of the water washing tank 2, and the sewage hole 27 is located on the bottom surface of the water washing tank 2 close to the side wall, so as to facilitate sewage discharge. The sewage hole 27 is used to clean the sediment at the bottom of the water washing tank 2. The oil drain port 26 is higher than the liquid level in the water washing tank 2, but the height of the oil on the liquid surface in the water washing tank 2 is the same height as the oil drain port 26. Specifically, the distance between the oil drain port 26 and the liquid level of the water washing liquid in the water washing tank 2 is 2mm-5mm. When the oil level continues to rise, the oil is discharged through the oil drain port 26.

[0051] The oil discharge port 26 is provided with a recovery component 8, which includes a recovery box 81, a recovery ball 82 and a collection box 83. The recovery box 81 is installed in the water washing tank 2. The oil discharge port 26 is connected to the recovery box 81, and the recovery box 81 is sealed and only connected to the water washing tank 2 through the oil discharge port 26. An oil discharge pipe 84 is provided on the upper part of the recovery box 81. The opening of the oil discharge pipe 84 is installed with a cover 85. The oil discharge pipe 84 is horizontally suspended. The collection box 83 is provided with a filling port 86 for inserting the oil discharge pipe 84. The recovery ball 82 is connected to the bottom of the recovery box 81 and reciprocates to inject water into the recovery box. The box 81 is pushed and the oil in the recovery box 81 is discharged through the oil drain pipe 84. The recovery ball 82 can be set in a variety of ways. In one embodiment, the recovery ball 82 is a rubber ball, and the recovery ball 82 is filled with water. The recovery ball 82 can be squeezed to squeeze the original water in the recovery ball 82 into the recovery box 81, thereby raising the oil in the recovery box 81 and raising the oil to the oil drain pipe 84 to complete the recovery process of the oil to the collection box 83, thereby achieving uninterrupted reception of oil while regularly taking out the oil without having to take it out all the time.

[0052] In a further embodiment, the side of the recovery ball 82 is also connected to the middle of the water washing tank 2, and a manual valve is installed on the pipe connecting the recovery ball 82 and the water washing tank 2. The valve can be controlled to control the water in the water washing tank 2 to enter the recovery ball 82. Therefore, when the water in the water washing tank 2 is replaced in large capacity, when the oil is recovered at this time, the oil level can be raised by injecting water in the water washing tank 2 into the recovery ball 82, and then the main sediment is discharged through the drain hole 27, and then the water with reduced sediment is discharged through the wastewater drainage cleaning component 4 and utilized. In this process, the water in the water washing tank 2 is discharged to the middle height of the water washing tank 2. At this time, the water in the recovery ball 82 can be discharged back to the water washing tank 2, retaining only the water level needed when pressing the recovery ball 82, and then replenishing water through the water replenishment pipe 54. At this time, the water pump 51 is turned off, and only the water replenishment operation is performed until the water washing tank 2 returns to the rated water level.

[0053] Due to the setting of the above-mentioned recovery ball 82 and the connection between the recovery ball 82 and the water washing tank 2, during the use of the equipment, even if the continuous water replenishment state is exceeded and the excess water enters the recovery box 81, it can be reset by regularly replacing the liquid in the water washing tank 2, without affecting the recovery of the oil. If the water replenishment state is insufficient, the time for shutting down the water pump 51 can be increased when replacing the liquid in the water washing tank 2 on a large scale to discharge the oil, thereby realizing the periodic reset of the state of the water washing tank 2.

[0054] Reference Figure 4 、 Figure 5 and Figure 7The above-mentioned wastewater discharge and cleaning assembly 4 specifically includes a discharge pipe 41, a cleaning sleeve 42, a receiving box 43, a stirring barrel 44, a detergent bottle 45 and a scraper 46. The receiving box 43 is located below the feeding device 1 and the washing tank 2 for receiving sediment and wastewater, wherein the cleaning sleeve 42 and the scraper 46 are installed and fixed on the feeding bracket 14 up and down, and the cleaning sleeve 42 is installed on the side of the rubber conveyor belt 12 away from the feeding tank 11. The cleaning sleeve 42 is long and has a long strip opening for discharge on the side of the cleaning sleeve 42 facing the rubber conveyor belt 12. The long strip opening extends along the width direction of the rubber conveyor belt 12 and covers the rubber conveyor belt 12. Water is poured toward the rubber conveyor belt 12 through the long strip opening, and there is a certain distance between the cleaning sleeve 42 and the rubber conveyor belt 12, but the distance between the cleaning sleeves 42 is small to ensure that the water can be completely poured onto the rubber conveyor belt 12. The scraper 46 contacts the rubber conveyor belt 12, and the rubber conveyor belt 12 is cleaned more thoroughly by the scraper 46.

[0055] The scraper 46 may be a rubber scraper 46 or a fluff scraper 46 .

[0056] One end of the drain pipe 41 is connected to the bottom of the water washing tank 2 , and the other end extends downward to the feeding device 1 to be connected to the cleaning sleeve 42 and supply water to the cleaning sleeve 42 .

[0057] The stirring barrel 44 is fixed at the bottom of the washing tank 2, and the detergent bottle 45 is installed on the stirring barrel 44. At the same time, the stirring barrel 44 is installed on the discharge pipe 41. The discharge pipe 41 is supported accordingly by the stirring barrel 44 and the cleaning sleeve 42. The upper part of the stirring barrel 44 is a cylindrical pipe pile and the lower part is funnel-shaped. The space inside the stirring barrel 44 is set as a sedimentation space 441. The stirring barrel 44 is provided with a sewage outlet 442 at the bottom and a sewage cover 443 for closing the sewage outlet 442 is installed. A scraper 46 is provided to remove large particles of impurities and improve the cleaning effect of the scraper 46 on the rubber conveyor belt 12. The stirring barrel 44 is used to further precipitate impurity particles.

[0058] The stirring barrel 44 is provided with a detergent filling port 444. The detergent bottle 45 is filled with detergent and the detergent is injected into the stirring barrel 44 through the detergent filling port 444, so that the stirring barrel 44 is also used to mix the waste water and detergent. Specifically, the wastewater excretion cleaning component 4 also includes a power fan blade 47, a stirring fan blade 48 and a power component 49 associated with the power fan blade 47 and the stirring fan blade 48. The power fan blade 47 is installed in the discharge pipe 41 and rotates under the drive of the liquid flow. The stirring fan blade 48 is installed in the stirring barrel 44. The power fan blade 47 and the stirring fan blade 48 are synchronously rotated by the power component 49. In order to install the power fan blades 47, one section of the discharge pipe 41 is disc-shaped with a hollow interior for the power fan blades 47 to be rotatably installed. An angle is cut off from the top of the mixing barrel 44 near the power fan blades 47 to form an inclined mounting surface 440 that is consistent with the downward inclination of the discharge pipe 41. The opening of the mixing barrel 44 for discharging water into the discharge pipe 41 is located on the same side as the inclined mounting surface 440. The mixing fan blades 48 are located below the inclined mounting surface 440 in the mixing barrel 44, close to the water outlet of the mixing barrel 44. The power assembly 49 is located on the inclined mounting surface 440. At the same time, the mixing fan blades 48 are tilted upward to push the liquid to flow toward the barrel wall of the mixing barrel 44.

[0059] The detergent filling inlet 444 is opened on the inclined mounting surface 440, and the detergent bottle 45 is provided with a liquid outlet 451. The detergent bottle 45 is mounted on the mixing barrel 44, and the liquid outlet 451 enters the mixing barrel 44 through the detergent filling inlet 444. The liquid outlet 451 is installed with a foaming cotton cloth 452. The detergent in the detergent bottle 45 continuously soaks the foaming cotton cloth 452. The foaming cotton cloth 452 prevents the detergent in the detergent bottle 45 from directly flowing out. Specifically, the liquid outlet 451 is directly mounted on the mixing barrel 44, and the liquid outlet 451 is partially located in the mixing barrel 44 and is installed with a foaming cotton cloth 452. The foam cloth 452 is partially immersed in the liquid in the mixing barrel 44, but due to the structure of the mixing barrel 44 and the inclination of the discharge pipe 41, the internal space of the mixing barrel 44 is not completely filled and there is a certain amount of air on the top, so that the foam cotton cloth 452 is only partially immersed in the liquid. The detergent bottle 45 is provided with a one-way valve to limit the gas to enter the detergent bottle 45 in one direction. At the same time, the liquid outlet nozzle 451 is located outside the mixing barrel 44 for the installation of the detergent bottle 45 in a horizontal direction, and the detergent bottle 45 is inserted and installed in the liquid outlet nozzle 451, so that the detergent bottle 45 is installed in a horizontal insertion manner, which is convenient for replacement.

[0060] At the same time, in order to limit the circulation of the detergent in the detergent bottle 45, the detergent is a gel-like thick detergent, the outflow speed is hindered by the foaming cotton cloth 452, and the dilution by the water flow continuously triggers the continuous outflow of the detergent.

[0061] The implementation principle of an energy-saving fastener heat treatment equipment in an embodiment of the present application is as follows: the fasteners are first washed with water and then enter the heat treatment furnace 3 for heat treatment. The fasteners are heated by the heat emitted from the heat treatment furnace 3 through the boiler 5, and then the hot water is directed to the water tank for fastener cleaning, so that the fasteners are pre-heated by hot water during the cleaning process, so that the fasteners have been heated to a certain extent before entering the heat treatment. The baffle 34 arranged between the boiler 5 and the lifting assembly 25, on the one hand, blocks the direct heating of the water washing equipment by the flame emitted from the heat treatment furnace 3, thereby reducing damage caused by overheating of the equipment. On the other hand, it also directs the emitted heat to the boiler 5 more fully, thereby improving the utilization efficiency of waste heat. Then, during operation, the oil drain port 26 continuously discharges oil. After the equipment has been used for a period of time, most of the sediment is discharged through the drain hole 27, and then the waste water is discharged and utilized through the drain pipe 41.

[0062] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
