Description

Technical Field

[0001] This application relates to the field of heat treatment, and particularly to an energy-saving fastener heat treatment device. Background Art

[0002] Heat treatment refers to a metal hot working process in which metal materials are heated, held, and cooled in the solid state to change the chemical composition and structure on the surface or inside of the materials and obtain the required properties; fasteners are also called standard parts in the market and are a general term for a class of mechanical parts used to firmly connect two or more parts (or components) into a whole; fasteners also need to undergo the above heat treatment process during production to improve their performance to meet the use requirements.

[0003] The fasteners are first washed with water, and the washed fasteners are sent into a heat treatment furnace for heat treatment. The fasteners entering the heat treatment furnace are heated to raise the temperature of the fasteners 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 has high energy consumption. Especially when heat-treating fasteners, since fasteners need to be continuously fed in and the heat-treated fasteners need to be sent out, heat is continuously lost during this process, increasing energy consumption. Summary of the Invention

[0005] In order to make more full use of the heat energy of the heat treatment equipment, this application provides an energy-saving fastener heat treatment device.

[0006] The energy-saving fastener heat treatment device provided by this application adopts the following technical solutions: An energy-saving fastener heat treatment device includes a water washing pool, a heat treatment furnace, and a boiler. The boiler is installed at the entrance where fasteners enter the heat treatment furnace and is located above. The heat treatment furnace includes a heat treatment conveyor belt. The water washing pool is provided with a lifting component for sending the washed fasteners onto the heat treatment conveyor belt. A baffle is arranged between the boiler and the lifting component. The baffle is located above the heat treatment conveyor belt, and the baffle is spaced from the entrance of the heat treatment furnace and guides the heat to rise. A water circulation pipeline is arranged between the boiler and the water washing pool, and a water pump for driving the water circulation to flow is arranged on the water circulation pipeline.

[0007] By adopting the above technical solution, after the fasteners are first washed with water and then enter the heat treatment furnace for heat treatment, the fasteners are cleaner before heat treatment. At the same time, the boiler uses the heat released from the outside of the heat treatment furnace for heating, and then guides the hot water to the water tank for cleaning the fasteners, so that the fasteners are preheated by the hot water during the cleaning process, and the fasteners are heated to a certain extent before entering the heat treatment, improving the heat treatment efficiency, making full use of the heat energy, and being more energy-saving. The baffle plate arranged between the boiler and the lifting assembly, on the one hand, blocks the direct heating of the equipment at the water washing place by the flame released from the outside of the heat treatment furnace, reducing the overheating damage of the equipment, and on the other hand, also guides the released heat more fully to the boiler, improving the waste heat utilization efficiency.

[0008] Optionally, it further includes a feeding device, and the feeding device includes a feeding pool, a rubber conveyor belt, a feeding driver for driving the rubber conveyor belt to run, a feeding support for installing the rubber conveyor belt and the feeding driver, and a magnetic attraction block installed in the feeding support. The feeding pool is located on the side of the rubber conveyor belt away from the water washing pool. The rubber conveyor belt passes through the feeding pool and runs upward and then flips over, passes through the upper opening of the water washing pool and returns to the feeding pool. The magnetic attraction block always adheres to the part of the rubber conveyor belt close to the feeding pool.

[0009] By adopting the above technical solution, in the way of magnetic attraction feeding, on the one hand, the rubber conveyor belt is supported by the magnetic attraction block, making the rubber conveyor belt run more stably and reducing the collision of the fasteners. On the other hand, the magnetic attraction feeding method also reduces the bumping and abrasion between the fasteners and the feeding device, making the fasteners not easy to be worn and damaged before heat treatment and improving the yield.

[0010] Optionally, it further includes a waste water discharge and cleaning assembly, and the waste water discharge and cleaning assembly includes a discharge pipe, a cleaning sleeve and a receiving box. One end of the discharge pipe is communicated with the bottom of the water washing pool, 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 pool. The cleaning sleeve is installed at one end of the discharge pipe close to the rubber conveyor belt. The cleaning sleeve is provided with a long strip opening for discharging, and the long strip opening extends along the width direction of the rubber conveyor belt and covers the rubber conveyor belt.

[0011] By adopting the above technical solution, after the wastewater drainage and cleaning component operates in the water washing pool for a period of time, it can drain the water in the water washing pool, thereby facilitating the replenishment of the water in the water washing pool, resetting the state of the water washing pool, ensuring the washing effect. At the same time, during the process of discharging wastewater, the discharged wastewater is used to clean the rubber conveyor belt, cleaning the oil adhered to the rubber conveyor belt, reducing the influence of the oil on the rubber conveyor belt on the fastener transportation, regularly cleaning the part of the oil adhered to the fasteners transferred to the rubber conveyor belt. The long strip opening enables the water discharged from the drain pipe to fully contact the entire rubber conveyor belt, ensuring the cleaning effect.

[0012] Optionally, the wastewater drainage and cleaning component further includes a stirring barrel and a detergent bottle. The stirring barrel is installed on the drain pipe. The stirring barrel is provided with a detergent filling port, and the detergent bottle is filled with detergent and injects the detergent into the stirring barrel through the detergent filling port.

[0013] By adopting the above technical solution, the stirring barrel and the detergent bottle are provided. The detergent bottle is used to fill the detergent into the stirring barrel, and the stirring barrel is used to stir and mix the detergent and the wastewater for cleaning the rubber conveyor belt.

[0014] Optionally, at least one part of the drain pipe is convex downward, and a precipitation space is formed inside. A sewage outlet is opened at the bottom of the precipitation space, and a sewage cover for closing the sewage outlet is installed.

[0015] By adopting the above technical solution, the precipitation space is provided for precipitating the sediment carried out by the drain pipe. By removing large particle impurities as much as possible, the cleaning effect of the wastewater on the rubber conveyor belt is improved, and at the same time, the influence of impurities on the rubber conveyor belt is reduced.

[0016] Optionally, the wastewater drainage and cleaning component further includes a power fan blade, a stirring fan blade, and a power component connecting the power fan blade and the stirring fan blade. The power fan blade is installed in the drain pipe and rotates driven by the liquid flow. The stirring fan blade is installed in the stirring barrel, and the power fan blade and the stirring fan blade rotate synchronously through the power component.

[0017] By adopting the above technical solution, the power fan blade not only transmits power to drive the stirring fan blade to rotate, utilizes the potential energy of the wastewater to drive the stirring fan blade to mix the detergent and the wastewater, but also plays a certain role in separating and stirring, reducing the flow velocity of the water flow and reducing the impact of impurity particles on the rubber conveyor belt.

[0018] Optionally, the stirring fan blade is installed at the water outlet of the stirring barrel, and the stirring fan blade is inclined upward to push the liquid to flow towards the barrel wall of the stirring barrel, and the detergent filling port is located in the direction where the stirring fan blade pushes the liquid to flow.

[0019] By adopting the above technical solutions, on the one hand, it conforms to the installation direction of the power component. On the other hand, if the detergent is not stirred evenly, it will also enter the drain pipe, and the subsequent power fan blades can also stir the detergent evenly. At the same time, the stirring fan 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 fan blades to accelerate. The rotation of the stirring fan blades hinders the increase of the 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 fan blades further block the entry of particulate matter. The stirring fan blades push upward to generate waves, bringing out the detergent, and it is not easy to disturb the precipitated particles.

[0020] Optionally, the detergent bottle is provided with a liquid outlet nozzle. The detergent bottle is installed on the stirring barrel, and the liquid outlet nozzle enters the stirring barrel through the detergent filling port. The liquid outlet nozzle 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.

[0021] By adopting the above technical solutions, the stirring fan blades push upward to generate waves and bring out the detergent from the foaming cotton cloth. The presence of the foaming cotton cloth better promotes the mixing of the detergent and the wastewater. At the same time, the foaming cotton cloth restricts the free outflow speed of the detergent, reducing the waste of the detergent.

[0022] Optionally, the boiler is provided with a water replenishing pipe and is externally connected to a water source. The water replenishing pipe is provided with a switch valve. The top of the water washing pool is provided with an oil drain port, and the bottom of the water washing pool is provided with a sewage discharge hole. The oil drain port is higher than the liquid level in the water washing pool, and the distance between the oil drain port and the liquid level of the washing liquid in the water washing pool is 2 mm - 5 mm.

[0023] By adopting the above technical solutions, the provided sewage discharge hole can be used to clean the sediment at the bottom of the water washing pool, ensuring the periodic restoration of the water washing pool. At the same time, after cleaning the main sediment, the reuse of the wastewater by the wastewater drainage and cleaning component can reduce the impact of the sediment on the wastewater reuse. The setting of the water replenishing pipe can supplement the water loss in the water washing pool during the use of the equipment. At the same time, after discharging the sediment and reusing the wastewater, it can quickly replenish water to achieve the reset of the equipment. At the same time, the setting of the oil drain port, and the certain distance between the oil drain port and the water surface in the water washing pool can discharge some surface floating oil, reducing the oil liquid washed from the fasteners by the water washing pool. Regularly cleaning the oil liquid can reduce the amount of oil liquid taken away again when the fasteners come out of the water washing pool, and at the same time, always maintain a certain oil level to heat the water in the water washing pool to ensure the preheating effect of the water temperature on the fasteners. The oil drain port also serves as a water level measurement to control the amount of water replenishment.

[0024] Optionally, a recovery assembly is provided at the oil drain port. The recovery assembly includes a recovery box, recovery balls, and a collection box. The recovery box is installed in the water washing tank, and the oil drain port communicates with the recovery box. A drain pipe is provided at the upper part of the recovery box, and a cover is installed at the opening of the drain pipe. The collection box is provided with a perfusion port for inserting the drain pipe. The recovery balls communicate with the bottom of the recovery box and reciprocally inject water into the recovery box, and push the oil in the recovery box to be discharged through the drain pipe.

[0025] By adopting the above technical solution, a recovery assembly is provided at the oil drain port to recover the oil through the recovery assembly. On the one hand, it reduces the pollution of the oil. On the other hand, the oil can be recovered and reused, such as for equipment lubrication. The recovery box receives the oil continuously overflowing from the oil drain port. When it is necessary to take out the oil from the recovery box, the cover is opened, and the collection box is installed on the drain pipe to receive the oil. At the same time, water is injected into the recovery box through the recovery balls, thereby raising the height of the oil in the recovery box and taking out all the oil in the recovery box as much as possible to complete the recovery of the oil. Such a recovery method not only ensures the uninterrupted recovery of the oil but also allows the oil to be recovered at any time, and the oil is not likely to overflow and cause pollution.

[0026] In summary, after the fasteners are first washed with water and then enter the heat treatment furnace for heat treatment, the fasteners are cleaner before heat treatment. At the same time, the boiler uses the heat released from the outside of the heat treatment furnace for heating, and then guides the hot water to the water tank for cleaning the fasteners, so that the fasteners are preheated by the hot water during the cleaning process, and the fasteners have been heated to a certain extent before entering the heat treatment, improving the heat treatment efficiency, making full use of the heat energy, and being more energy-saving. The baffle provided between the boiler and the lifting assembly, on the one hand, blocks the direct heating of the equipment at the water washing area by the flame released from the outside of the heat treatment furnace, reducing the overheating damage to the equipment. On the other hand, it also guides the released heat to the boiler more fully, improving the waste heat utilization efficiency. Description of the Drawings

[0029] The following further elaborates on the present application in conjunction with the attached Figure 1-8 drawings for a more detailed description.

[0030] The embodiment of the present application discloses an energy-saving fastener heat treatment equipment.

[0031] Referring to Figure 1 and Figure 2 , an energy-saving fastener heat treatment equipment includes a feeding equipment 1, a water washing pool 2, a heat treatment furnace 3, and a supporting wastewater discharge and cleaning component 4 and a boiler 5. The fasteners are fed into the water washing pool 2 by the feeding equipment 1 for cleaning and preheating, and then the fasteners in the water washing pool 2 are sent into the heat treatment furnace 3 to complete the heat treatment. Among them, the boiler 5 is installed at the inlet where the fasteners enter the heat treatment furnace 3 to absorb the waste heat dissipated by the heat treatment furnace 3. The boiler 5 and the water washing pool 2 are connected through a water circulation pipeline to increase the water temperature in the water washing pool 2. The wastewater discharge and cleaning component 4 is used for discharging, replacing, and reusing the water washing liquid in the water washing pool 2.

[0032] 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 to run, a feeding bracket 14 for installing the rubber conveyor belt 12 and the feeding driver 13, and a magnetic attracting block installed in the feeding bracket 14. In this embodiment, the feeding bracket 14 is composed of two left and right steel plates and multiple steel structure columns connecting the two steel plates into one body. The feeding driver 13 uses a motor and rollers. There are multiple rollers. The rubber conveyor belt 12 is reversely wrapped around all the rollers. The output shaft of the motor is connected to one of the rollers through a chain to realize the motor driving the roller to rotate, and then the continuous running of the rubber conveyor belt 12 is realized through the associated mechanism between the roller and the rubber conveyor belt 12. The two sides of the feeding tank 11 are installed on the two steel plates, and the feeding tank 11 is located on the side of the rubber conveyor belt 12 away from the water washing tank 2. The side of the feeding tank 11 away from the rubber conveyor belt 12 extends upward obliquely and is overhanging. The feeding tank 11 is a housing with an opening on the upper side and the side close to the rubber conveyor belt 12. Guide plates 111 are installed on the inner walls on both sides of the feeding tank 11 separated by the rubber conveyor belt 12. The distance between the two guide plates 111 is smaller closer to the rubber conveyor belt 12, so as to guide the fasteners in the feeding tank 11 to the rubber conveyor belt 12.

[0033] At the same time, the feeding tank 11 is located at the middle height of the feeding bracket 14. The middle part of the rubber conveyor belt 12 is in contact with the feeding tank 11. A magnetic attracting block is installed on the feeding bracket 14. The magnetic attracting block is located in the space surrounded by the rubber conveyor belt 12, and the magnetic attracting block only contacts the part of the rubber conveyor belt 12 above the feeding tank 11 on the side close to the feeding tank 11 and the upper side wall part of the rubber conveyor belt 12, so that the rubber conveyor belt 12 sends the feeding tank 11 to adsorb the fasteners and carries the fasteners over the feeding bracket 14 and then discharges the materials.

[0034] In this embodiment, the above magnetic attracting block can adopt an electromagnet, so that it is convenient to control whether to feed the fasteners according to the situation, and it is also convenient to automate the feeding process.

[0035] Refer to Figure 2 and Figure 3 , the water washing tank 2 is located between the heat treatment furnace 3 and the feeding device 1. The water washing tank 2 is a housing with an opening at the 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 a bottom surface composed of two inclined surfaces. In order to close the opening above the water washing tank 2, reduce liquid splashing and loss, and at the same time ensure that the fasteners can enter and exit the water washing tank 2 conveniently, a closing plate 22 is installed in the middle of the top of the water washing tank 2. A first inlet housing 23 is installed on the side of the top of the water washing tank 2 close to the feeding device 1. A second inlet housing 24 is installed on the side of the water washing tank 2 close to the heat treatment furnace 3. The sides of the first inlet housing 23 and the second inlet housing 24 away from each other and the downward side are open.

[0036] The first receiving plate 6 for canal excavation is installed on the loading support 14. The first receiving plate 6 is inclined up and down. The higher side of the first receiving plate 6 is fixed to the loading support 14 and is located below the part where the rubber conveyor belt 12 passes over the highest point after passing through the loading tank 11 to receive the falling fasteners. The lower side of the first receiving plate 6 enters the interior of the first inlet housing 23 and is located above the washing space 21 of the washing tank 2 to convey the fasteners into the washing space 21.

[0037] The heat treatment furnace 3 includes a heating furnace 31 and a heat treatment conveyor belt 32 that continuously moves the fasteners inside the heating furnace 31. A part of the heat treatment conveyor belt 32 extends outside the heating furnace 31. A waste heat utilization frame 33 and a baffle 34 are installed on the support of the part of the heat treatment conveyor belt 32 located outside the heating furnace 31. The baffle 34 is located on the side of the waste heat installation frame away from the heating furnace 31. The waste heat utilization frame 33 is located at the entrance of the heating furnace 31 for the fasteners to enter. The distance between the waste heat utilization frame 33 and the heat treatment conveyor belt 32 is sufficient for the fasteners to pass through. The flame inside the heating furnace 31 hits the baffle 34 through the space between the waste heat utilization frame 33 and the heat treatment conveyor belt 32. The distance between the baffle 34 and the heat treatment conveyor belt 32 is also sufficient for the fasteners to pass through.

[0038] The boiler 5 is installed on the waste heat utilization frame 33. The washing tank 2 is provided with a lifting component 25 for sending the washed fasteners into the heat treatment conveyor belt 32. The bottom of the lifting component 25 is located at the bottom of the washing space 21. In order to install the lifting component 25, a lifting support 35 is provided on the side of the heat treatment conveyor belt 32 away from the heating furnace 31. The top of the lifting component 25 passes through the opening of the second inlet housing 24 and is installed on the lifting support 35. A motor and a reducer for driving the lifting component 25 are installed above the lifting support 35. A second receiving plate 7 is also installed on the lifting support 35. The second receiving plate 7 is also inclined up and down. The higher side of the second receiving plate 7 is located below the part after the lifting component 25 passes over the top to receive the fasteners brought out after washing from the washing tank 2. The lower side of the first receiving plate 6 is located above the heat treatment conveyor belt 32 to convey the fasteners into the heat treatment furnace 3.

[0039] A water circulation pipeline is provided between the boiler 5 and the water washing pool 2. A water pump 51 for driving the water circulation to flow is provided on the water circulation pipeline. Specifically, the water circulation pipeline includes a water outlet pipe 52 and a water inlet pipe 53. One end of the water inlet pipe 53 is connected to the middle of the water washing pool 2, and the other end is connected to the boiler 5. The water pump 51 is installed on the water inlet pipe 53. The water pump 51 continuously pumps water from the water washing pool 2 and sends it into the boiler 5. Moreover, the height of the boiler 5 is higher than that of the water washing pool 2. The hot water in the boiler 5 continuously flows back to the water washing pool 2 under the action of gravity. One end of the water outlet pipe 52 is connected to the boiler 5, and the other end is connected to the bottom of the water washing pool 2. The positions where the water inlet pipe 53 and the water outlet pipe 52 are connected to the water washing pool 2 are respectively located on both sides of the water washing pool 2 to ensure the water temperature at the bottom of the water washing pool 2. The water in the water washing pool 2 is sent into the boiler 5 through the water inlet pipe 53, and the water in the boiler 5 is sent into the water washing pool 2 through the water outlet pipe 52. Among them, the pipeline part of the above-mentioned water outlet pipe 52 is laid inside the waste heat utilization rack 33, so as to make more full use of waste heat.

[0040] Meanwhile, 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. When the water in the boiler 5 overheats, the steam has a discharge port. At the same time, it is ensured that the liquid in the boiler 5 freely flows back to the water washing pool 2 under the action of gravity, ensuring that the flow is always smooth, which is beneficial to the liquid cleaning during maintenance.

[0041] The boiler 5 is also provided with a water replenishing pipe 54 and is externally connected to a water source. The water replenishing pipe 54 is provided with a switch valve 55. The water replenishing rate of the water replenishing pipe 54 into the boiler 5 is close to the overall rate of various losses of the liquid in the water washing. Moreover, the difference between the rate of draining water from the boiler 5 to the water washing pool 2 and the rate of pumping water from the water washing pool 2 by the water pump 51 is also close to the rate of water loss in the water washing pool 2. The process of replenishing water ensures the water level in the boiler 5, thereby ensuring the draining rate and also ensuring the water level in the water washing pool 2.

[0042] Refer to Figure 4 and Figure 6 At the same time, an oil discharge port 26 is provided at the top of the water washing pool 2, and a sewage discharge hole 27 is provided at the bottom of the water washing pool 2. The oil discharge port 26 is located on the side of the water washing pool 2, and the sewage discharge hole 27 is located at a position close to the side wall on the bottom surface of the water washing pool 2, so as to facilitate the operation of sewage discharge. The sewage discharge hole 27 is used to clean the sediment at the bottom of the water washing pool 2. The oil discharge port 26 is higher than the liquid level in the water washing pool 2, but the height of the oil on the liquid surface in the water washing pool 2 is equal to that of the oil discharge port 26. Specifically, the interval between the oil discharge port 26 and the liquid level of the water washing liquid in the water washing pool 2 is 2 mm - 5 mm. When the height of the oil liquid continuously rises, the oil liquid is discharged through the oil discharge port 26.

[0043] An oil drain port 26 is provided with a recovery assembly 8. The recovery assembly 8 includes a recovery box 81, a recovery ball 82 and a collection box 83. The recovery box 81 is installed in the water washing pool 2. The oil drain port 26 communicates with the recovery box 81. And the recovery box 81 is airtight and only communicates with the water washing pool 2 through the oil drain port 26. A drain pipe 84 is provided at the upper part of the recovery box 81. A cover 85 is installed at the opening of the drain pipe 84. The drain pipe 84 is horizontally suspended. The collection box 83 is provided with a perfusion port 86 for the drain pipe 84 to be inserted. The recovery ball 82 communicates with the bottom of the recovery box 81 and reciprocates to inject water into the recovery box 81, and pushes the oil liquid in the recovery box 81 to be discharged through the drain pipe 84. There are various setting methods for the recovery ball 82. In one implementation, the recovery ball 82 is made of a rubber ball. The inside of the recovery ball 82 is filled with water. By squeezing the recovery ball 82, the original water in the recovery ball 82 can be squeezed into the recovery box 81, thereby raising the oil liquid in the recovery box 81 to the drain pipe 84 to complete the recovery process of the oil liquid into the collection box 83. Thus, while continuously receiving oil liquid, the oil liquid can be taken out regularly without having to take it all the time.

[0044] In a further implementation, the side of the recovery ball 82 also communicates with the middle part of the water washing pool 2, and a manual valve is installed on the pipeline connecting the recovery ball 82 and the water washing pool 2. By controlling the valve, the water in the water washing pool 2 can be controlled to enter the recovery ball 82. Thus, when the water in the water washing pool 2 is replaced in a large volume and oil liquid is recovered at this time, the height of the oil liquid can be raised by injecting the water in the water washing pool 2 into the recovery ball 82, and then the main sediment is discharged through the sewage discharge hole 27, and then the water with reduced sediment is discharged through the waste water drainage and cleaning assembly 4 and utilized. In this process, the water in the water washing pool 2 is discharged to the middle height of the water washing pool 2. At this time, the water in the recovery ball 82 can be discharged back to the water washing pool 2, only retaining the water level required for pressing the recovery ball 82, and then water is replenished through the water replenishing pipe 54. At this time, the water pump 51 is turned off and only the water replenishing operation is carried out until the water washing pool 2 returns to the rated water level.

[0045] Due to the setting of the above-mentioned recovery ball 82 and the connection between the recovery ball 82 and the water washing pool 2, during the use of the equipment, even if the continuous water replenishment state is exceeded and the extra water enters the recovery box 81, it can be reset when the liquid in the water washing pool 2 is replaced regularly, without affecting the recovery of the oil liquid. And when the water replenishment state is insufficient, the time for turning off the water pump 51 can also be increased when the liquid in the water washing pool 2 is replaced on a large scale to discharge the oil liquid, realizing the periodic reset of the state of the water washing pool 2.

[0046] Refer to Figure 4 、 Figure 5 and Figure 7The above-mentioned wastewater discharge and cleaning component 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 fixedly installed 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 in a long strip shape, and the cleaning sleeve 42 is provided with a long strip opening for discharge on the side 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 spacing 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.

[0047] The scraper 46 may be a rubber scraper 46 or a fluff scraper 46 .

[0048] One end of the discharge 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 to supply water to the cleaning sleeve 42 .

[0049] The stirring barrel 44 is fixedly installed at the bottom of the washing tank 2, the detergent bottle 45 is installed on the stirring barrel 44, and the stirring barrel 44 is installed on the discharge pipe 41 at the same time. The discharge pipe 41 is supported 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 outlet cover 443 for closing the sewage outlet 442 is installed. The scraper 46 is matched 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 the impurity particles.

[0050] The stirring barrel 44 is provided with a detergent filling port 444. The detergent bottle 45 is filled with detergent and injects the detergent into the stirring barrel 44 through the detergent filling port 444, so that the stirring barrel 44 is also used to mix wastewater and detergent. Specifically, the wastewater discharge and cleaning assembly 4 further includes a power fan blade 47, a stirring fan blade 48, and a power assembly 49 that connects 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 driven by 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 through the power assembly 49. In order to install the power fan blade 47, a section of the discharge pipe 41 is in a disc shape with a hollow interior for the power fan blade 47 to be rotatably installed. One corner of the top of the stirring barrel 44 near the power fan blade 47 is cut off to form an inclined installation surface 440 that is consistent with the downward inclination direction of the discharge pipe 41. The opening of the stirring barrel 44 where water flows out into the discharge pipe 41 and the inclined installation surface 440 are located on the same side. The stirring fan blade 48 is located below the inclined installation surface 440 in the stirring barrel 44 near the water outlet of the stirring barrel 44. The power assembly 49 is located on the inclined installation surface 440. At the same time, the stirring fan blade 48 pushes the liquid upward obliquely to flow towards the barrel wall of the stirring barrel 44.

[0051] The detergent filling port 444 is opened on the inclined installation surface 440. The detergent bottle 45 is provided with a liquid outlet nozzle 451. The detergent bottle 45 is installed on the stirring barrel 44, and the liquid outlet nozzle 451 enters the stirring barrel 44 through the detergent filling port 444. A foaming cotton cloth 452 is installed on the liquid outlet nozzle 451. 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 flowing out directly. Specifically, the liquid outlet nozzle 451 is directly installed on the stirring barrel 44. A part of the liquid outlet nozzle 451 is located inside the stirring barrel 44 and the foaming cotton cloth 452 is installed, and a part of the foaming cotton cloth 452 is immersed in the liquid in the stirring barrel 44. However, due to the structure of the stirring barrel 44 and the inclination of the discharge pipe 41, the internal space of the stirring barrel 44 is not completely filled and there is a certain amount of air at the top, so that the foaming 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 only in one direction. At the same time, the opening of the liquid outlet nozzle 451 outside the stirring barrel 44 for installing the detergent bottle 45 is horizontally oriented, and the detergent bottle 45 is inserted and installed on the liquid outlet nozzle 451, so that the detergent bottle 45 is installed in a horizontal insertion manner, which is convenient for replacement.

[0052] At the same time, in order to limit the flow of the detergent in the detergent bottle 45, a colloidal and thick detergent is used. The foaming cotton cloth 452 hinders the outflow speed, and through the dilution of the water flow, the continuous outflow of the detergent is continuously triggered.

[0053] The implementation principle of an energy-saving fastener heat treatment device according to an embodiment of the present application is as follows: After the fasteners are washed with water first, they then enter the heat treatment furnace 3 for heat treatment. The boiler 5 uses the heat released from the outside of the heat treatment furnace 3 for heating, and then guides the hot water to the water tank for fastener cleaning, so that the fasteners are pre-heated by the hot water during the cleaning process, and the fasteners have been heated to a certain extent before entering the heat treatment. The baffle 34 provided 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 released from the outside of the heat treatment furnace 3, reducing the overheating damage of the equipment; on the other hand, it also guides the released heat more fully to the boiler 5, improving the waste heat utilization efficiency. Then, during operation, the oil drain port 26 continuously discharges the oil liquid. After using the equipment for a period of time, most of the sediment is discharged through the sewage discharge hole 27, and then the waste water is discharged and utilized through the drain pipe 41.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
