Description

Technical Field

[0001] This invention relates to a casting production line, specifically an auxiliary water cooling system for a sand removal system and a casting production line having the auxiliary water cooling system. Background Technology

[0002] In existing casting production processes, after the sand removal system (such as a drum sand removal machine) separates the castings from the molding sand, the discharged castings and molding sand usually have a high temperature (up to 400-600℃).

[0003] These high-temperature materials can cause a series of problems: First, high-temperature materials dissipate heat slowly, affecting the efficiency of subsequent conveying and processing; second, high-temperature materials can easily burn subsequent conveying equipment (such as apron conveyors), causing thermal deformation and accelerated wear of the equipment, increasing maintenance costs; at the same time, high-temperature dust can also have an adverse impact on the workshop environment.

[0004] Existing patent CN 222221114 U discloses an energy-saving structure for a sand cooling drum. Based on its disclosure, it can be known that the sand cooling drum itself has a water spraying device, but its discharge end does not have an additional cooling structure.

[0005] On the other hand, the scale conveyor used to transport high-temperature castings operates under harsh conditions of heavy load, high temperature and high dust for a long time, and its side transmission mechanism such as chain, sprocket, and idler roller is very prone to wear due to friction.

[0006] Existing lubrication devices are often complex in layout, requiring additional mounting brackets or occupying ground space. They also rely heavily on power units such as electric pumps, which not only increases equipment costs and energy consumption but also makes it inconvenient to modify existing production lines. It is difficult to quickly and cost-effectively adapt to the protective railing structure of existing casting production lines.

[0007] Therefore, how to effectively solve the problem of rapid cooling of high-temperature materials after sand falling and / or to carry out convenient and low-cost lubrication and maintenance of conveying equipment has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0008] The purpose of this invention is to provide a cooling system or device that can quickly reduce the temperature of materials discharged from a drum sand remover.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0010] An auxiliary water cooling system for a sand removal system, the sand removal system including a drum sand removal machine; the drum sand removal machine including a water circuit system; including a water cooling component disposed at the sand discharge end of the drum sand removal machine; the water cooling component being connected to the water circuit system in the drum sand removal machine; the water cooling component being used to cool the high-temperature material at the sand discharge end of the drum sand removal machine.

[0011] The water-cooling assembly includes at least one cooling water pipe and a spray head; one end of the cooling water pipe is connected to the water system, and the other end is connected to the spray head; the spray head sprays cooling water onto the surface of the high-temperature material towards the sand discharge end.

[0012] The cooling water pipeline is connected to the water system in the drum sand remover via quick connectors or control valves.

[0013] The cooling water pipes are made of wear-resistant and corrosion-resistant materials, and the outer wall of the cooling water pipes is covered with a heat insulation protective layer.

[0014] A casting production line includes a sand removal system, a casting conveying system, and a post-processing system; the sand removal system is connected to the post-processing system through the casting conveying system; the sand removal system includes a drum sand removal machine and an auxiliary water cooling system for the sand removal system.

[0015] The casting conveying system includes a casting conveying line, protective railings, and a suspended lubrication unit for the slab conveyor; the protective railings are arranged at the edge of the casting conveying line; the suspended lubrication unit for the slab conveyor is located above the casting conveying line.

[0016] The suspended lubrication unit for the scale conveyor includes a liquid supply structure and a spraying structure, wherein the liquid supply structure stores the lubricating medium.

[0017] The liquid supply structure includes a liquid supply tank;

[0018] The spray structure includes a spray pipe connected to a liquid supply tank, and the lubricating medium in the liquid supply tank can enter the spray pipe.

[0019] The liquid supply structure also includes a hanging mechanism, which includes a hanging hook connected to the liquid supply tank;

[0020] The suspended lubrication unit of the scale conveyor is attached to the guardrail via a hanging mechanism.

[0021] The hanging hook includes a bottom support frame, and at least two inverted U-shaped hooks are provided at the edge of the bottom support frame; one end of the inverted U-shaped hook is connected to the bottom support frame, and the other end extends freely.

[0022] The spray structure also includes a support pole, on which the spray pipe is arranged; the spray pipe is connected to the support pole in a detachable manner.

[0023] The mounting pole of the suspended lubrication unit is connected to the guardrail, and the spray pipe connected to the mounting pole extends towards the casting conveyor line; the lubricating medium in the supply tank can be sprayed onto the casting conveyor line by gravity.

[0024] The support pole is arranged at an angle and extends toward the side drive mechanism of the slab conveyor in the casting conveyor line.

[0025] The advantages of this invention are:

[0026] This invention discloses an auxiliary water cooling system for a sand removal system and a casting production line having the auxiliary water cooling system.

[0027] By adding a water-cooling component connected to the original water system at the discharge end of the drum sand remover, cooling water can be directly sprayed onto the hot material that has just been discharged using spray nozzles. This can quickly reduce the material temperature, effectively prevent damage such as thermal deformation and accelerated wear to subsequent conveying equipment caused by high temperature, and extend the service life of the equipment.

[0028] The cooling water pipeline connects to the existing water system of the drum sand remover via quick couplings or control valves, enabling rapid connection and independent control without requiring large-scale modifications to the existing water system, thus reducing modification costs and construction difficulty. Furthermore, the pipeline is made of wear-resistant and corrosion-resistant materials and is covered with an insulation layer, making it suitable for the harsh environment of the foundry site.

[0029] The suspended lubrication unit adopts a hanging structure, which can be directly hung on the protective railing at the edge of the casting conveyor line without the need for additional installation brackets or occupying ground space. Its simple structure and flexible layout allow for gravity-driven spraying of the lubricating medium, eliminating the need for an additional power unit and significantly reducing manufacturing costs and operating energy consumption.

[0030] The spray pipes are detachably connected to the inclined support poles, allowing for precise alignment with the side drive mechanisms (chains, sprockets, etc.) of the apron conveyor, achieving accurate lubrication and preventing media waste. The liquid supply tank and the mounting mechanism use a plug-in positioning system, and the spray pipes are detachable for easy cleaning, replacement, or maintenance.

[0031] By combining cooling and lubrication, the problem of damage to equipment caused by high-temperature materials is solved, and the smooth operation of the conveying system is ensured. The overall structural modification is simple and highly practical, effectively improving the operational stability and production efficiency of the casting production line.

Detailed Implementation

[0039] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0040] This invention discloses an auxiliary water cooling system for a sand removal system and a casting production line using the same, aiming to solve the heat dissipation problem of high-temperature castings and molding sand after sand removal in the existing casting production process, as well as the problem that high-temperature castings and molding sand can easily burn equipment and affect the efficiency of subsequent conveying and processing, while also taking into account the lubrication and maintenance needs of the conveying equipment.

[0041] The auxiliary water cooling system for the sand removal system of this invention is mainly applied to sand removal systems that include a drum sand removal machine, which itself is equipped with a water circuit system 1-5. The core improvement of this embodiment is that a water cooling component 1-6 is added to the sand removal discharge end of the drum sand removal machine. This water cooling component 1-6 is connected to the water circuit system 1-5 of the drum sand removal machine, and can directly cool the high-temperature material discharged from the sand removal discharge end.

[0042] The water-cooling assembly 1-6 mainly includes cooling water pipes 1-61 and spray heads 1-63. One end of the cooling water pipes 1-61 is connected to the water system 1-5, and the other end is connected to the spray heads 1-63. The spray heads 1-63 are positioned facing the sand discharge end, and can uniformly spray cooling water onto the surface of the high-temperature castings and molding sand. The advantage of this structural design is that it can quickly reduce the temperature of the material by direct spraying when the material is discharged from the drum sand remover at a high temperature, avoiding thermal deformation and accelerated wear of subsequent conveying equipment caused by high temperature, while reducing the impact of high-temperature dust on the workshop environment.

[0043] For ease of installation and maintenance, cooling water pipe 1-61 is connected to the water system 1-5 of the drum sand remover via quick couplings or control valve 1-62. This eliminates the need for large-scale modifications to the existing water system, enabling rapid integration and independent control with the existing water supply system, thus reducing modification costs and construction difficulty. Furthermore, cooling water pipe 1-61 is made of wear-resistant and corrosion-resistant materials and has an outer heat-insulating protective layer, effectively resisting dust, high-temperature moisture, and corrosive media in the foundry environment, extending pipe lifespan, and reducing downtime for maintenance due to pipe damage.

[0044] The structure of the casting production line using this water-cooling system:

[0045] The casting production line disclosed in this invention includes a sand removal system, a casting conveying system 1-02, and a post-processing system. The sand removal system is connected to the post-processing system through the casting conveying system 1-02. The sand removal system adopts the above-mentioned drum sand removal machine with an auxiliary water cooling system.

[0046] The casting conveying system 1-02 includes a casting conveying line, a protective guardrail 1-3, and a suspended lubrication unit 1-01 for the apron conveyor. The casting conveying line serves as the carrier for casting transfer, driving the casting to move from the sand removal system to the post-processing system. The protective guardrail 1-3 is arranged at the edge of the casting conveying line to prevent the casting from falling off the conveying line during the conveying process. It also serves to protect the operators and prevent them from accidentally contacting the conveying line and causing safety accidents.

[0047] The suspended lubrication unit 1-01 for the apron conveyor is attached to the guardrail 1-3 and is located above the casting conveyor line. Its main function is to lubricate the apron conveyor 1-4 in the casting conveyor line, reduce friction loss during the operation of the apron conveyor 1-4, extend the service life of the equipment, and ensure smooth operation of the apron conveyor 1-4 to avoid the conveyor line jamming due to excessive friction, which would affect the casting transfer efficiency.

[0048] The suspended lubrication unit 1-01 for the apron conveyor includes a liquid supply structure 1-1 and a spray structure 1-2. The liquid supply structure 1-1 stores lubricating medium to provide a continuous lubricating medium for the spray structure 1-2. The liquid supply structure 1-1 includes a liquid supply tank 11, which stores the lubricating medium. Its capacity is adapted to the operating requirements of the production line, ensuring a continuous supply of lubricating medium to the spray structure 1-2 without frequent replenishment. The spray structure 1-2 includes a spray pipe 21, which is connected to the liquid supply tank 11. The lubricating medium in the liquid supply tank 11 can enter the spray pipe 21 and be evenly sprayed onto the key parts of the apron conveyor 1-4 through the spray pipe 21, achieving precise lubrication while avoiding waste of lubricating medium.

[0049] The fluid supply structure 1-1 also includes a hanging mechanism, which includes a hanging hook 23 connected to the fluid supply tank 11. The hanging hook 23 is used to hang the entire lubrication unit on the protective railing 1-3, enabling convenient installation and removal of the lubrication unit and facilitating subsequent maintenance and repair. The hanging hook 23 includes a bottom support frame 232, which supports the fluid supply tank 11 and ensures the stability of the fluid supply tank 11 after hanging. At least two inverted U-shaped hooks 231 are provided at the edge of the bottom support frame 232. One end of the inverted U-shaped hook 231 is connected to the bottom support frame 232, and the other end extends freely. The structure of the inverted U-shaped hook 231 is adapted to the shape of the protective railing 1-3, and can be firmly hung on the protective railing 1-3 to prevent the lubrication unit from falling off during use and ensure the stability of the lubrication operation.

[0050] The spray structure 1-2 also includes a support rod 22, on which the spray pipe 21 is arranged. The support rod 22 is used to fix the position of the spray pipe 21, ensuring that the spray pipe 21 can be aligned with the key lubrication parts of the scale conveyor 1-4, so that the lubricating medium can be sprayed accurately, improving the lubrication effect. At the same time, it prevents the spray pipe 21 from shifting its position due to its own weight or vibration of the conveyor line, which would affect the normal operation of the lubrication.

[0051] The suspended lubrication unit 1-01 for the apron conveyor includes a liquid supply structure 1-1 and a spray structure 1-2. The liquid supply structure 1-1 stores a lubricating medium and includes a liquid supply tank 11. The spray structure 1-2 includes a spray pipe 21 connected to the liquid supply tank 11, allowing the lubricating medium in the liquid supply tank 11 to enter the spray pipe 21. The spray pipe 21 is connected to the liquid supply tank 11 via a control valve 1-62, which controls the movement of the lubricating medium from the liquid supply tank 11 to the spray pipe 21. The suspended lubrication unit 1-01 disclosed in this invention is mainly used to supply lubricating medium to the side transmission mechanism in the apron conveyor 1-4. Furthermore, the overall structure and layout of the suspended lubrication unit 1-01 disclosed in this invention are relatively simple; it can supply and store oil through the liquid supply structure 1-1, and spray the lubricating medium onto the area to be lubricated through the spray structure 1-2; and it does not require an additional power unit, but can achieve the spraying of the lubricating medium by gravity based solely on the actual plant layout; thereby achieving the lubrication of the moving friction parts such as chains, sprockets, idlers or bearings of the scale conveyor 1-4.

[0052] In this invention, the casting production line mainly includes a sand removal system, a casting conveying system 1-02, and a post-processing system; the sand removal system is connected to the post-processing system through the casting conveying system 1-02; the casting conveying system 1-02 includes a casting conveying line, a protective railing 1-3, and a suspended lubrication unit 1-01 for the slab conveyor; the protective railing 1-3 is arranged at the edge of the casting conveying line; the suspended lubrication unit 1-01 for the slab conveyor is hung on the protective railing 1-3 through a hanging mechanism; the suspended lubrication unit 1-01 for the slab conveyor is located above the casting conveying line. Casting conveyor line: As the core carrier for casting transfer, it adopts apron conveyors 1-4, adapted to the production cycle of a 555 / H wet molding sand production line (90-110 molds / hour). It can withstand the impact of high-temperature castings at 400-600℃, and features heavy load capacity, wear resistance, and high-temperature resistance. It enables stable and continuous conveying of castings, ensuring that castings are not damaged or detached during transfer. Its open structure facilitates the collection and removal of loose sand from the casting surface. Additionally, protective railings 1-3: Located at the edges of the casting conveyor line, they are made of high-strength carbon steel, possessing good structural strength and protective properties. Yes, its core function is to ensure production safety, preventing operators from accidentally touching the high-temperature casting conveyor line and high-temperature castings, thus avoiding safety accidents such as burns and falls. Simultaneously, the protective railing 1-3 also serves as the mounting carrier for the suspended lubrication unit 1-01 for the apron conveyor, eliminating the need for additional mounting brackets, simplifying the production line layout, and reducing equipment addition costs. The suspended lubrication unit 1-01 for the apron conveyor, as a key auxiliary component of the casting conveying system 1-02, is attached to the protective railing 1-3 via its own hooking mechanism, and is arranged above the casting conveyor line without affecting the normal conveying of castings. This lubrication unit is precisely adapted to the apron conveyor 1-4 of the casting conveyor line. Its spray structure 1-2 extends towards the side transmission mechanism (chain, sprocket, idler roller, bearing, etc.) of the apron conveyor 1-4, enabling precise spraying of the lubricating medium and providing continuous and stable lubrication to the moving parts of the apron conveyor 1-4.

[0053] This invention discloses a suspended lubrication unit 1-01 for a slat conveyor and a casting production line with the lubrication unit. It solves the technical problems of complex layout, high cost of addition and need for additional power drive of the existing lubrication device of the slat conveyor 1-4. It realizes convenient and low-cost lubrication of the side transmission mechanism of the slat conveyor 1-4, adapts to the harsh working conditions of high temperature and high dust in the casting workshop, and ensures the continuous and stable operation of the slat conveyor 1-4.

[0054] The suspended lubrication unit 1-01 for the scale conveyor is based on the integrated design of "liquid storage-liquid control-spraying". The whole adopts a suspended layout, which does not require ground space and can be flexibly adapted to the existing protective railing 1-3 of the casting production line. Its structure mainly includes a liquid supply structure 1-1 and a spraying structure 1-2. The two work together to realize the storage, transportation and spraying of lubricating medium. The entire process does not require an additional power unit and can complete the lubrication operation by relying solely on gravity.

[0055] The liquid supply structure 1-1, serving as the core for storing and supplying the lubricating medium, mainly includes a liquid supply tank 11 and a hanging mechanism. The liquid supply tank 11 stores the lubricating medium, while the hanging mechanism suspends and fixes the entire lubrication unit in a designated position, enabling convenient installation and disassembly. The hanging mechanism includes a hanging hook 23 connected to the liquid supply tank 11. The hanging hook 23 consists of a bottom support frame 232 and at least two inverted U-shaped hooks 231. One end of the inverted U-shaped hook 231 is fixedly connected to the bottom support frame 232, while the other end extends freely. The hooks 231 allow for quick attachment to the protective railing 1-3 of the casting production line without requiring modification of the existing railing, resulting in high installation convenience. The bottom support frame 232 adopts a grid structure, which not only ensures structural strength but also provides stable support for the liquid supply tank 11. The bottom of the liquid supply tank 11 is provided with at least one protrusion. Through the insertion and cooperation of the protrusion with the bottom support frame 232, the liquid supply tank 11 and the hanging mechanism can be quickly positioned and fixed, preventing the liquid supply tank 11 from shifting or falling off during equipment operation vibration.

[0056] The supply tank 11 includes a tank body 101. A replenishment port is located at the top of the tank body 101 for periodic replenishment of the lubricating medium. The replenishment port can be equipped with a sealing cap 103 to prevent sand, dust, and moisture from the foundry workshop from entering the tank body 101 and contaminating the lubricating medium. An outlet is located at the bottom or side of the tank body 101, serving as an output channel for the lubricating medium. This outlet connects to the spray structure 1-2 to achieve directional delivery of the lubricating medium. The outlet's location at the bottom of the tank body 101 facilitates the discharge of lubricating oil, while its location on the side allows the lubricating medium to form a settling zone during discharge. Because the outlet is on the side, it must be at least 2-5 cm away from the bottom of the tank body 101; this design ensures the lubricating medium has its own settling ability.

[0057] The spray structure 1-2 serves as the conveying and spraying mechanism for the lubricating medium. It mainly includes a spray pipe 21 and a support rod 22. The spray pipe 21 sprays the lubricating medium onto the area to be lubricated, while the support rod 22 secures the spray pipe 21, ensuring its installation stability and spray angle. The spray pipe 21 is connected to the outlet of the supply tank 11 via a control valve 1-62. The control valve 1-62 controls the movement of the lubricating medium from the supply tank 11 to the spray pipe 21, enabling on-demand supply of the lubricating medium. The spray volume and frequency can be adjusted according to the operating conditions of the apron conveyor 1-4 to avoid waste while ensuring effective lubrication. The spray pipe 21 is detachably connected to the support rod 22, facilitating future maintenance, cleaning, or replacement, and is suitable for use under long-term high-dust conditions.

[0058] This invention also discloses a casting production line that integrates the aforementioned suspended lubrication unit 1-01. The production line mainly includes a sand removal system, a casting conveying system 1-02, and a post-processing system. The sand removal system is connected to the post-processing system via the casting conveying system 1-02, realizing fully automated conveying of castings from sand removal to post-processing. The casting conveying system 1-02 includes a casting conveyor line, protective railings 1-3, and the suspended lubrication unit 1-01 for the apron conveyor. The protective railings 1-3 are arranged at the edge of the casting conveyor line, providing safety protection and serving as the mounting carrier for the suspended lubrication unit 1-01.

[0059] The suspended lubrication unit 1-01 is attached to the protective railing 1-3 via a hook-up mechanism, and is positioned above the casting conveyor line, without affecting the normal conveying of castings. Simultaneously, it ensures that the spray structure 1-2 can accurately target the area to be lubricated. The mounting rod 22 in the spray structure 1-2 is connected to the protective railing 1-3, and is arranged at an angle, extending towards the side transmission mechanism of the apron conveyor 1-4 in the casting conveyor line. This allows the spray pipe 21 connected to the mounting rod 22 to extend towards the side transmission mechanism, ensuring that the lubricating medium in the supply tank 11 can be accurately sprayed onto the side transmission mechanism of the apron conveyor 1-4 under gravity, achieving targeted lubrication of moving friction parts such as chains, sprockets, rollers, or bearings.

[0060] The core advantage of this invention lies in the simple overall structure and layout of the suspended lubrication unit 1-01. It requires no additional power unit and can achieve the spraying of lubricating medium solely by gravity, significantly reducing the manufacturing cost and operating energy consumption of the lubrication unit. The hook-on design makes the arrangement of the lubrication unit extremely convenient and can be quickly adapted to the existing protective railings 1-3 of the casting production line without large-scale modification of the production line, greatly reducing the cost of adding a lubrication unit. At the same time, the detachable connection and precise spraying design facilitate later maintenance and ensure lubrication effect, effectively extending the service life of the apron conveyor 1-4 and ensuring the continuous and stable operation of the casting production line. Detailed Implementation

[0061] This embodiment provides a suspended lubrication unit 1-01 for a slab conveyor and a casting production line with the lubrication unit, which is adapted to the slab conveyor 1-4 in the wet sand casting production line. It is used to lubricate the side transmission mechanism of the slab conveyor 1-4 and is suitable for the high temperature, high dust and heavy load operating conditions of the casting workshop.

[0062] The suspended lubrication unit 1-01 for the scale conveyor includes a liquid supply structure 1-1 and a spray structure 1-2. The liquid supply structure 1-1 stores a lubricating medium, which can be lubricating oil or lubricating grease. The lubricating medium can effectively reduce the friction and wear of the moving parts of the scale conveyor 1-4.

[0063] The liquid supply structure 1-1 includes a liquid supply tank 11 and a connecting mechanism. The liquid supply tank 11 is made of stainless steel or plastic. The tank body 101 of the liquid supply tank 11 has a rectangular structure. The upper end of the tank body 101 is provided with a circular liquid inlet, which is equipped with a threaded sealing cap 103. After tightening, the tank body 101 can be sealed to prevent contamination of the lubricating medium. The side of the tank body 101 is provided with a liquid outlet, which uses a stainless steel connector for easy connection to subsequent pipelines.

[0064] The hanging mechanism includes a hanging hook 23 connected to the liquid supply tank 11. The hanging hook 23 is made of carbon steel and is treated with anti-corrosion to improve its service life. The bottom support frame 232 of the hanging hook 23 is grid-shaped, and the grid size is adapted to the bottom size of the liquid supply tank 11. The bottom of the tank 101 has two symmetrically arranged protrusions, which are cylindrical and match the grid holes of the bottom support frame 232. The liquid supply tank 11 is inserted into the bottom support frame 232 through these two protrusions, achieving quick positioning and fixation, and effectively preventing the liquid supply tank 11 from shifting when the equipment vibrates. Two symmetrically arranged inverted U-shaped hooks 231 are provided at the edge of the bottom support frame 232. One end of the inverted U-shaped hook 231 is welded and fixed to the bottom support frame 232, and the other end extends freely. The inner diameter of the inverted U-shaped hook 231 is adapted to the diameter of the crossbar of the protective railing 1-3 of the casting production line, which can be quickly hung on the protective railing 1-3 without additional fasteners, making installation convenient.

[0065] The spray structure 1-2 includes a spray pipe 21, a support rod 22, and a control valve 1-62. The control valve 1-62 is a manual valve, installed at the outlet of the supply tank 11, which allows manual adjustment of the output of the lubricating medium to achieve lubrication on demand. When the scale conveyor 1-4 stops running, the control valve 1-62 can be closed to avoid wasting the lubricating medium. The spray pipe 21 is made of oil-resistant rubber tubing, which has good flexibility and oil resistance, and can be adapted to the inclined arrangement of the support rod 22. One end of the spray pipe 21 is connected to the control valve 1-62 through a connector.

[0066] The support pole 22 is made of stainless steel round tube, with one end welded to the guardrail 1-3, and the other end extending at an angle of 15° towards the side transmission mechanism of the apron conveyor 1-4. This angle ensures that the lubricating medium in the supply tank 11 can be smoothly sprayed out through the spray holes of the spray pipe 21 under the action of gravity, and can accurately cover the moving friction parts such as the chain and idler rollers of the apron conveyor 1-4. The spray pipe 21 is detachably connected to the support pole 22 by pipe clamps or straps 25. The installation position and angle of the spray pipe 21 can be adjusted according to the spraying requirements, and it is also convenient for the spray pipe 21 to be disassembled, cleaned and replaced later.

[0067] The casting production line in this embodiment includes a sand removal system, a casting conveying system 1-02, and a post-processing system. The sand removal system separates the cooled castings from the molding sand. The casting conveying system 1-02 transports the sand-removed castings from the sand removal system to the post-processing system, which performs shot blasting, grinding, and flaw detection on the castings. The casting conveying system 1-02 includes a casting conveyor line, protective railings 1-3, and a suspended lubrication unit 1-01 for the aforementioned apron conveyor. The casting conveyor line uses an apron conveyor 1-4 to transport high-temperature castings. The protective railings 1-3 are made of carbon steel and welded to the edges of both sides of the casting conveyor line for safety protection, preventing operators from accidentally touching high-temperature equipment or castings from falling.

[0068] The suspended lubrication unit 1-01 is attached to the crossbar of the guardrail 1-3 via the inverted U-shaped hook 231 of the hanging mechanism, positioned above the casting conveyor line without affecting the normal conveying of castings. The support rod 22 is welded to the inside of the guardrail 1-3 and extends at an angle towards the side transmission mechanism of the apron conveyor 1-4, allowing the spray pipe 21 to be precisely aligned with the side transmission mechanism. The lubricating oil in the supply tank 11, under the action of gravity, enters the spray pipe 21 through the outlet and control valve 1-62, and then is evenly sprayed through the spray holes on the spray pipe 21 onto the moving friction parts of the apron conveyor 1-4, such as the chain, sprocket, idler roller, and bearings, achieving lubrication of these parts.

[0069] The usage process of this embodiment is as follows: First, inject an appropriate amount of lubricating oil into the supply tank 11 through the replenishment port at the upper end of the supply tank 11, and tighten the sealing cap 103; then, hang the inverted U-shaped hook 231 of the hanging hook 23 on the crossbar of the guardrail 1-3, adjust the position of the supply tank 11, and ensure that the protrusion at the bottom of the tank 101 is precisely inserted into the mesh hole of the bottom support frame 232 to fix the supply tank 11; next, adjust the position and angle of the spray pipe 21 to ensure that the spray hole can be accurately aligned with the side transmission mechanism of the apron conveyor 1-4; finally, open the control valve 1-62, adjust the opening of the control valve 1-62 according to the operating conditions of the apron conveyor 1-4, control the spray volume of the lubricating medium, and under the action of gravity, the lubricating medium is sprayed to the part to be lubricated through the spray pipe 21 to achieve lubrication of the apron conveyor 1-4. When it is necessary to replenish the lubricating medium, close the control valve 1-62, open the sealing cover 103 of the replenishment port, and replenish the lubricating medium; when it is necessary to maintain the spray pipe 21, remove the pipe clamp, and the spray pipe 21 can be removed from the support pole 22 for cleaning or replacement.

[0070] The beneficial effects of this embodiment are as follows: the suspended lubrication unit 1-01 has a simple overall structure and reasonable layout. It can be quickly hung on the protective railing 1-3 through the hanging mechanism, which is convenient to arrange and does not require modification of the existing production line, thus greatly reducing the cost of adding a lubrication unit; no additional power unit is required, and the spraying of the lubricating medium can be achieved by gravity alone, which reduces the operating energy consumption; the spray pipe 21 is detachable, which facilitates later maintenance; through the above design, the service life of the apron conveyor 1-4 can be effectively extended, ensuring the continuous and stable operation of the casting production line.

[0071] Overall workflow and collaborative effects:

[0072] In this embodiment, when the casting production line is working, the roller shakeout machine completes the separation of castings and molding sand. When the high-temperature material is discharged from the shakeout discharge end, the shakeout system is started with an auxiliary water cooling system. Cooling water enters the cooling water pipeline 1-61 through the water system 1-5 and is sprayed evenly onto the surface of the high-temperature material through the spray nozzles 1-63 to quickly reduce the material temperature and avoid thermal damage to subsequent conveying equipment. At the same time, it can cool and clean the high-temperature material (high-temperature castings and molding sand) and reduce the residual molding sand on the high-temperature castings.

[0073] After cooling, the material enters the casting conveying system 1-02 and is conveyed to the post-processing system along the casting conveyor line. During the process, the suspended lubrication unit 1-01 of the apron conveyor is stably installed on the guardrail 1-3 through the hanging mechanism. The lubricating medium in the supply tank 11 is transported by gravity through the spray pipe 21 to the transmission mechanism of the apron conveyor 1-4 to achieve continuous lubrication, reduce equipment wear, and extend the service life of the conveyor line.

[0074] This embodiment solves the problem of the impact of high-temperature materials on subsequent equipment by adding a water cooling system at the sand discharge end. At the same time, a hanging lubrication unit 1-01 that can be installed quickly is designed to take into account the cooling and equipment maintenance needs in the casting production process. The overall structural modification is simple and highly practical, which can effectively improve the operational stability and production efficiency of the casting production line.

[0075] The casting production line in this embodiment includes a sand removal system, a casting conveying system 1-02, and a post-processing system. The sand removal system is connected to the post-processing system via the casting conveying system 1-02. The sand removal system includes a drum sand removal machine and an auxiliary water cooling system. The drum sand removal machine itself has a water system 1-5 for routine cooling or cleaning. The auxiliary water cooling system is located at the sand removal discharge end of the drum sand removal machine and mainly includes a water cooling component 1-6. This water cooling component 1-6 is connected to the water system 1-5 in the drum sand removal machine, and its function is to forcibly cool the high-temperature material at the sand removal discharge end.

[0076] Specifically, the water-cooling assembly 1-6 includes at least one cooling water pipe 1-61 and a spray head 1-63 connected to the end of the cooling water pipe 1-61. One end of the cooling water pipe 1-61 is connected to the water system 1-5 in the drum sand remover via a quick connector or control valve 1-62, and the other end is connected to the spray head 1-63. The spray direction of the spray head 1-63 is towards the sand discharge end, thus enabling direct spraying of cooling water onto the surface of the high-temperature material. The quick connector facilitates disassembly and maintenance, while the control valve 1-62 can adjust the cooling water flow rate to meet the cooling requirements of different materials. To improve durability and cooling effect, the cooling water pipe 1-61 is made of wear-resistant and corrosion-resistant material and is covered with a heat-insulating protective layer on its outer wall. This prevents damage to the pipe from high-temperature materials or the environment and reduces the temperature rise of the cooling water during transportation, ensuring the efficiency of spray cooling.

[0077] The casting conveying system 1-02 in this embodiment is used to transport castings processed by the sand removal system to the post-processing system. The casting conveying system 1-02 includes a casting conveyor line, protective railings 1-3 arranged at the edge of the casting conveyor line, and a suspended lubrication unit 1-01 for the slab conveyor. The suspended lubrication unit 1-01 is located above the casting conveyor line and is specifically used to lubricate the side drive mechanism of the slab conveyor 1-4. The suspended lubrication unit 1-01 mainly includes a liquid supply structure 1-1 and a spray structure 1-2. The liquid supply structure 1-1 stores the lubricating medium and specifically includes a liquid supply tank 11. A hooking mechanism is connected to the liquid supply tank 11, which includes a hanging hook 23 connected to the liquid supply tank 11. The hanging hook 23 consists of a bottom support frame 232 and at least two inverted U-shaped hooks 231, one end of which is connected to the bottom support frame 232, and the other end extends freely. With this structure, the entire liquid supply tank 11 can be stably hung on the protective railing 1-3 without the need for additional supports or fixing bolts, making installation and disassembly very convenient. The spray structure 1-2 includes a spray pipe 21 and a mounting pole 22. The spray pipe 21 is fixed to the mounting pole 22 by a detachable connection, facilitating replacement or cleaning. The mounting pole 22 itself is connected to the protective railing 1-3 and is arranged at an angle, with its inclination extending towards the side drive mechanism of the apron conveyor 1-4 in the casting conveyor line. The position and angle of the spray pipe 21 on the mounting pole 22 are adjustable, ensuring that the lubricating medium can be accurately sprayed onto the sprockets or chains that require lubrication.

[0078] The supply tank 11 and the spray pipe 21 are connected by a pipeline. The lubricating medium in the supply tank 11 flows naturally into the spray pipe 21 under its own gravity and flows out or sprays out from the outlet of the spray pipe 21, thus achieving gravity spray lubrication. This non-powered lubrication method is energy-saving and reliable, avoiding a complex pumping system. In actual operation, the suspended lubrication unit 1-01 is hung on the guardrail 1-3 through a hanging mechanism, and the mounting pole 22 is also fixed on the guardrail 1-3. The spray pipe 21 extends towards the casting conveyor line and is tilted to align with the side transmission mechanism. Under the action of gravity, the lubricating medium in the supply tank 11 continuously and slowly drips onto the drive chain or sprocket of the apron conveyor 1-4, effectively reducing wear and noise and ensuring the long-term stable operation of the casting conveyor line.

[0079] In summary, this embodiment achieves rapid cooling of high-temperature materials by installing water-cooling components 1-6 at the discharge end of the drum sand remover, which is beneficial for subsequent conveying and processing. Simultaneously, a suspended lubrication unit 1-01 is installed above the casting conveyor line, flexibly mounted via a hook-and-loop connection, and precisely lubricates the apron conveyor 1-4 using gravity flow, significantly improving the convenience of lubrication maintenance and the reliability of the conveying system. The entire casting production line has a compact structure and complementary functions, demonstrating good practicality and economy.
