Description

Technical Field

[0001] This utility model relates to the technical field of heating dewaxing devices, and in particular to a progressive heating dewaxing device. Background Technology

[0002] Heating dewaxing devices are widely used in the industrial field, mainly to remove wax residue from the surface of metal parts to ensure the quality of subsequent processes (such as electroplating and spraying). In addition to electric heating, some devices use gas or steam heating, which is suitable for large industrial scenarios. Electric heating can be divided into resistance wire heating or induction heating.

[0003] For example, patent application number 202220462312.4 published on the China Patent Network, entitled "A Heated Wax Removal Device," includes a housing and a water tank. A hydraulic rod is located at the top center of the housing. The bottom end of the cylinder of the hydraulic rod is fixedly connected to the shaft of a motor. The top end of the hydraulic rod penetrates the top center of the housing and is fixedly connected to the top end of a fixed rod. A cleaning brush is fixedly connected to the bottom end of the fixed rod. In this invention, high-intensity water spray is applied to the area requiring wax removal via a spray nozzle. The motor drives the hydraulic rod to rotate, which in turn drives the cleaning brush to rotate and clean. Simultaneously, the hydraulic rod drives the cleaning brush to move up and down for cleaning, resulting in excellent cleaning performance. The water is filtered through a first layer of mesh filter plates, a second layer of filter boxes, and a third layer of sedimentation tanks. The settled water is then pumped out by a third water pump and passed through a third pipe back to the housing for reuse, thus avoiding water waste.

[0004] However, in order to achieve the effect of gradual heating and dewaxing, the dewaxing equipment is equipped with multiple heating wires that generate different temperature steps. The continuous operation of a large number of heating wires will consume a lot of energy, which will affect the environmental protection effect of the dewaxing device. Utility Model Content

[0005] The purpose of this invention is to solve the problem that a large amount of energy is consumed when a large number of heating wires operate simultaneously in the existing technology, and to propose a progressive heating dewaxing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A progressive heating dewaxing device includes a water tank, with several diversion plates fixedly connected inside the water tank. The diversion plates are used to divide the space inside the water tank. Several heating wires located on both sides of the diversion plates are fixedly connected to the bottom of the inner wall of the water tank. The rightmost heating wire is in a normally open state and maintains the highest required temperature. The water heated by the rightmost heating wire flows through the top of the diversion plate and sequentially into the space divided by the leftmost diversion plate.

[0008] As a preferred technical solution of this application, both sides of the inside of the water tank are connected to the support rollers, the surface of the support rollers is covered with a conveyor belt, the top of the conveyor belt carries the product, and the support rollers, the conveyor belt and the product are all immersed in the liquid inside the water tank.

[0009] As a preferred technical solution of this application, a water pump is fixedly connected to the right side of the water tank, the output end of the water pump is connected to the right side of the water tank, the input end of the water pump is connected to a return pipe, and the end of the return pipe away from the water pump extends through the front of the water tank to the left side of the water tank and is connected to the water tank.

[0010] As a preferred technical solution of this application, guide plates are fixedly connected to both sides of the inner wall of the water tank. The guide plates are set to be inclined upwards, and the guide plates can push the product upwards by the inclined surface when the conveyor belt carries the product to the far right.

[0011] As a preferred technical solution of this application, connecting blocks are fixedly connected to both sides of the top of the water tank, and a shaft is movably connected to the inner side of the connecting blocks. Lifting frames are fixedly connected to both sides of the surface of the shaft, and the side of the lifting frame away from the shaft extends to the inner side of the guide plate.

[0012] As a preferred technical solution of this application, both ends of the shaft are fixedly connected to sleeve plates, and both ends of the right support roller extend to the outside of the water tank and are fixedly connected to a rotating wheel. A sliding rod located inside the sleeve plate is fixedly connected to the outside of the rotating wheel, and the sliding rod is slidably connected to the sleeve plate.

[0013] Compared with the prior art, this utility model provides a progressive heating dewaxing device, which has the following beneficial effects:

[0014] 1. This progressive heating dewaxing device significantly reduces total energy consumption by keeping only the rightmost heating wire constantly open while the others are closed. The diversion plate divides the water tank space, forcing water to overflow from the high-temperature zone on the right to the low-temperature zone on the left, forming a progressive temperature gradient. This avoids heat waste caused by direct mixing of hot and cold liquids. Heat is naturally transferred through the water flow, reducing the impact of frequent starting and stopping of the heating wires on temperature and extending the equipment's lifespan.

[0015] 2. This progressive heating and dewaxing device ensures uniform heating of all parts by immersing the product in liquid throughout the process, avoiding local temperature differences that could lead to wax residue or product deformation. The conveyor belt continuously moves the product, enabling automated batch operations, improving efficiency and reducing manual intervention.

[0016] 3. This progressive heating dewaxing device uses a pump to draw the low-temperature liquid on the left back to the heating zone on the right, circulating and preheating the cold water. This reduces the energy loss from the heating wire repeatedly heating the cold water. The combination of forced circulation and natural overflow maintains stable temperature in each zone and shortens the liquid heating time.

[0017] 4. This progressive heating dewaxing device automatically lifts the product out of the liquid surface when it moves to the far right, avoiding surface scratches caused by traditional mechanical gripping. It uses the mechanical energy of the conveyor belt to trigger the lifting action, eliminating the need for an additional power source, simplifying the structure and saving energy.

[0018] 5. The progressive heating dewaxing device has its shaft linked to the lifting frame via a connecting block, ensuring that the lifting timing is strictly matched with the movement of the conveyor belt to prevent products from jamming or falling. The lifting mechanism is integrated into the top of the water tank, reducing external mechanical devices and lowering maintenance difficulty and space occupation.

[0019] 6. This progressive heating dewaxing device uses a rotating support roller to drive a sleeve plate via a rotating wheel and a sliding rod, converting horizontal rotation into vertical movement of the lifting frame, achieving pure mechanical power transmission with high reliability and zero energy consumption.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Reference Figure 1-4A progressive heating dewaxing device includes a water tank 1. Several diversion plates 2 are fixedly connected inside the water tank 1, dividing the space within the tank. Several heating wires 3 are fixedly connected to the bottom of the inner wall of the water tank 1, located on both sides of the diversion plates 2. The rightmost heating wire 3 is normally open and maintains the highest required temperature. The water heated by the rightmost heating wire 3 flows sequentially through the top of the diversion plate 2 to the space divided by the leftmost diversion plate 2. By keeping only the rightmost heating wire 3 open and the others closed, the total energy consumption is significantly reduced. The diversion plates 2 divide the space of the water tank 1, forcing the water to overflow from the high-temperature zone on the right to the low-temperature zone on the left, forming a progressive temperature gradient. This avoids heat waste caused by direct mixing of hot and cold liquids. Heat is naturally transferred through the water flow, reducing the temperature impact caused by frequent starting and stopping of the heating wires 3, and extending the equipment lifespan. Support rollers 4 are driven to both sides inside the water tank 1. A conveyor belt 5 is fitted onto the surface of the support rollers 4, and the top of the conveyor belt 5 carries a product 6. The support rollers 4, conveyor belt 5, and product 6 are all immersed in... The product 6 is submerged in liquid in a water tank 1. A water pump 7 is fixedly connected to the right side of the water tank 1. The output end of the water pump 7 is connected to the right side of the water tank. A return pipe 8 is connected to the input end of the water pump 7. The end of the return pipe 8 away from the water pump 7 extends through the front of the water tank 1 to the left side of the water tank 1 and is connected to the water tank 1. Guide plates 9 are fixedly connected to both sides of the inner wall of the water tank 1. The guide plates 9 are set to be inclined upwards. When the conveyor belt 5 carries the product 6 to the far right, the guide plates 9 can push the product 6 upwards through the inclined surface. Connecting blocks 10 are fixedly connected to both sides of the top. A shaft 11 is movably connected to the inner side of the connecting blocks 10. Lifting frames 12 are fixedly connected to both sides of the surface of the shaft 11. The side of the lifting frame 12 away from the shaft 11 extends to the inner side of the guide plate 9. Sleeves 13 are fixedly connected to both ends of the shaft 11. Both ends of the right support roller 4 extend to the outside of the water tank 1 and are fixedly connected to the rotating wheel 14. A sliding rod 15 located inside the sleeve 13 is fixedly connected to the outside of the rotating wheel 14. The sliding rod 15 is slidably connected to the sleeve 13.

[0028] Specifically, during operation / use of this progressive heating dewaxing device: After the device is started, the rightmost heating wire 3 continues to operate, heating the liquid in its area to the highest temperature required for dewaxing. The water pump 7 starts, pumping the low-temperature liquid on the left side of the water tank 1 to the right side through the return pipe 8, forming a circulating water flow from right to left. The diversion plate 2 divides the water tank 1 into multiple independent areas, forcing the water to overflow from the top of each diversion plate 2, gradually transferring heat to the left area, forming a temperature gradient from right to left. The product 6 is carried by the conveyor belt 5, entering from the left side of the water tank 1 and being completely immersed in the liquid. As the conveyor belt 5 moves slowly to the right, the product 6 passes through the low-temperature to high-temperature areas in sequence. The gradual increase in liquid temperature softens and peels off the wax layer, avoiding damage to the product 6 caused by sudden high temperatures. At the same time, only the rightmost heating wire 3 continues to operate, significantly reducing energy consumption. When the product 6 moves to the rightmost side, the conveyor belt 5 drives the right support roller 4 to rotate. Through the linkage between the rotating wheel 14 and the slide bar 15, the shaft 11 is driven to rotate, causing the lifting frame 12 to swing upward. The inclined surface of the guide plate 9 cooperates with the lifting frame 12 to lift the product 6 out of the liquid surface, completing the dewaxing process. The lifting action is synchronized with the movement of the conveyor belt 5, realizing automated discharge. The water pump 7 continuously draws the low-temperature liquid on the left to the heating area on the right. Combined with the separation effect of the diverter plate 2, it reduces the direct mixing of hot and cold liquids and maintains the temperature gradient. The high-temperature liquid on the right slowly preheats the left area through natural overflow and forced circulation, maximizing heat recovery and reducing the energy waste caused by the repeated start and stop of the heating wire 3.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
