Description

Technical Field

[0001] This utility model relates to the field of heat exchange device technology, specifically a raw material preheating heat exchange device. Background Technology

[0002] Heat exchangers and waste heat boilers are widely used in industries such as petroleum refining, chemical engineering, and pharmaceuticals. Under certain operating conditions, the welding requirements for the heat exchanger tube ends are quite high. For example, the welding area needs to be preheated to a certain temperature before welding can proceed; otherwise, the overall quality of the equipment will be affected. Currently, regarding the welding requirements for waste heat boiler tube ends, the preheating temperature is getting higher and higher, and the requirements for heating and preheating devices are also increasing accordingly.

[0003] In existing pipe head heating and preheating equipment, a tracked electric heater is fixed to the surface of the pipe sheet with wire and covered with a whole piece of insulation cotton. Once the temperature reaches the required level for pipe head welding, the electric heating block and the insulation cotton in the welding area need to be removed before welding begins. However, the electric heating block that remains is still in operation; it is exposed without any protective device. Welders are at risk of burns if they accidentally touch the heating block, posing a significant safety hazard. Therefore, this heating equipment suffers from low production efficiency, serious energy waste, and a high risk of burns. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides a raw material preheating heat exchange device, which solves the problems mentioned above.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a raw material preheating heat exchange device, comprising a water inlet device, a heat exchange device, a water outlet device, a heating material, and a heat flow. The left side of the water inlet device is snap-fitted to the heat exchange device, and the right side of the water outlet device is snap-fitted to the heat exchange device. The heat flow and the heating material flow into the water inlet device from the left and right ends, respectively, and flow out from the water outlet device. The heat exchange device comprises a water baffle plate, a cover-shaped interface plate, a pointed interface plate, and round holes. The cover-shaped interface plate is fixedly connected to the pointed interface plate through the water baffle plate. Round holes are provided at the four corners of the water baffle plate. The heat exchange device is formed by two such symmetrical structures slidingly connected in a staggered manner.

[0008] Preferably, the water inlet device includes a water inlet baffle plate, a material inlet pipe, and a hot flow inlet pipe. The hot flow inlet pipe and the material inlet pipe are fixedly connected to the round holes on the left and right sides of the water inlet baffle plate, respectively. The tip interface plate passes through the water inlet baffle plate and connects to the hot flow inlet pipe. Each pipe connection is equipped with a sealing strip to ensure the airtightness of the entire device and prevent leakage.

[0009] Preferably, the water outlet device includes a water outlet baffle plate, a water outlet cover-shaped interface plate, a logistics pipe, and a hot flow pipe. The hot flow pipe and the logistics pipe are fixedly connected to the round holes on the left and right sides of the water outlet baffle plate, respectively. The cover-shaped interface plate passes through the water outlet baffle plate and is connected to the hot flow inlet pipe. The water outlet device and the water inlet device are mirror images of each other, so that the various cavities in the middle are spaced apart, dividing the cavities into heated materials and hot flow, ensuring that the heated materials and hot flow flowing into the water inlet device flow out from the outlet on the same side of the water outlet device.

[0010] Preferably, the cover-shaped interface plate includes a cover-shaped interface outer plate, a cover-shaped interface water pipe, and a cover-shaped interface plate groove.

[0011] Preferably, the tip interface plate includes a tip interface outer plate and a tip interface water pipe. The inner wall of the tip interface outer plate is fixedly connected to the tip interface water pipe. The tip interface outer plate and the tip interface water pipe fit the groove of the cover interface plate of the cover interface plate in size, and the contact surface is sealed and smooth to ensure the sealing of the joint and prevent liquid from entering the plate and forming liquid accumulation, which would cause the structure to fail to close tightly.

[0012] Preferably, the cover-shaped interface plate includes a cover-shaped interface outer shell, a rubber ring, wax, and a spring. The cover-shaped interface outer shell, which is wrapped with wax, is fixedly connected to the left side of the rubber ring. The cover-shaped interface plate is fixedly connected to the water-blocking plate by the spring. The front end of the tip interface water pipe is needle-shaped. The spring prevents the joint from falling off, and the needle-shaped tip allows it to move outward under pressure to ensure that it is in the same direction.

[0013] (III) Beneficial Effects

[0014] This utility model provides a raw material preheating heat exchange device. It has the following beneficial effects: by setting up a heat exchange device, the heat exchange device expands and contracts at different temperatures, increasing and decreasing the contact and flow rate of heat flow with the material to achieve stable and gradual control. This eliminates the need for users to actively contact the preheating heat exchange device, preventing safety hazards and improving user safety and convenience. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1 This utility model provides a technical solution for a raw material preheating heat exchange device: A raw material preheating heat exchange device includes a water inlet device 1, a heat exchange device 2, a water outlet device 3, a heated material 4, and a heat flow 5. The left side of the water inlet device 1 is snapped to the heat exchange device 2, and the right side of the water outlet device 3 is snapped to the heat exchange device 2. The heat flow 5 and the heated material 4 flow into the water inlet device 1 from the left and right ends, respectively, and flow out from the water outlet device 3. The heat exchange device 2 includes a water baffle plate 21, a cover-shaped interface plate 22, a pointed interface plate 23, and a round hole 24. The cover-shaped interface plate 22 is fixedly connected to the pointed interface plate 23 through the water baffle plate 21. The four corners of the water baffle plate 21 are provided with round holes 24. The heat exchange device 2 is formed by two such symmetrical structures slidingly connected in an alternating manner.

[0031] Please see Figure 2 The water inlet device 1 includes a water inlet baffle plate 11, a material inlet pipe 12, and a hot flow inlet pipe 13. The hot flow inlet pipe 13 and the material inlet pipe 12 are fixedly connected to the round holes 24 on the left and right sides of the water inlet baffle plate 11, respectively. The pointed interface plate 23 passes through and connects to the water inlet baffle plate 11 and the hot flow inlet pipe 13. Sealing strips are provided at all pipe connections to ensure the airtightness of the entire device and prevent leakage. The water outlet device 3 includes a water outlet baffle plate 31, a water outlet cap-shaped interface plate 32, and a material flow pipe. 32 and hot flow pipe 34, hot flow pipe 34 and flow pipe 32 are respectively fixedly connected to the openings of the round holes 24 on the left and right sides of the water outlet baffle plate 31. The cover-shaped interface plate 22 passes through the water outlet baffle plate 31 and is connected to the hot flow inlet pipe 13. The structure of the water outlet device 3 and the water inlet device 1 is mirror image and symmetrical to each other, so that the various cavities in the middle are separated and the cavities are divided into heated material 4 and hot flow 5, ensuring that the heated material 4 and hot flow 5 flowing into the water inlet device 1 flow out from the outlet on the same side of the water outlet device 3.

[0032] Please see Figures 3-7 The cover-shaped interface plate 22 includes a cover-shaped interface outer plate 221, a cover-shaped interface water pipe 222, and a cover-shaped interface plate groove 223. The inner wall of the cover-shaped interface outer plate 221 is fixedly connected to the cover-shaped interface water pipe 222. The cover-shaped interface outer plate 221 and the cover-shaped interface water pipe 222 have a cover-shaped interface plate groove 223 on their inner sides. The inside of the cover-shaped interface plate groove 223 is smooth to reduce resistance and prevent jamming. The tip interface plate 23 includes a tip interface outer plate 231 and a tip interface water pipe 232. The inner wall of the tip interface outer plate 231 is fixedly connected to the tip interface water pipe 232. The tip interface outer plate 231 and the tip interface water pipe 232 fit the size of the cover-shaped interface plate groove 223 of the cover-shaped interface plate 22, and the contact surface is sealed and smooth to ensure the sealing of the joint and prevent liquid from entering the plate and forming liquid accumulation that would prevent the structure from closing tightly.

[0033] Please see Figure 8 The cover-shaped interface plate 22 includes a cover-shaped interface outer shell 2211, a rubber ring 2212, wax 2213, and a spring 2214. The cover-shaped interface outer shell 2211 wraps around the wax 2213 and is fixedly connected to the left side of the rubber ring 2212. The cover-shaped interface plate 22 is fixedly connected to the water-proof plate 21 through the spring 2214. The front end of the tip interface water pipe 232 is needle-shaped. The spring prevents the joint from falling off, and the needle-shaped tip allows it to move outward under pressure to ensure the same direction.

[0034] Before use, the hot flow flows from the hot flow inlet pipe 13 on the left side of the water inlet device 1 through the odd-numbered chambers of the heat exchange device 2, and then through the pipeline channel composed of the cap-shaped interface water pipe 222 and the tip interface water pipe 232 of the even-numbered chambers into the next odd-numbered chamber, and finally flows out from the hot flow outlet pipe 33 on the left side of the water outlet device 3.

[0035] The material flows from the hot flow inlet pipe 13 on the right side of the water inlet device 1 through the pipeline channel composed of the cap-shaped interface water pipe 222 and the tip interface water pipe 232 of the even-numbered chambers into the next even-numbered chamber, and finally flows out through the hot flow outlet pipe 33 on the right side of the water outlet device 3.

[0036] In use, the odd-numbered chambers of the hot flow heat the material in the even-numbered chambers through heat conduction. As the heat increases, the wax 2213 in the cap-shaped interface plate 22 melts and changes from solid to liquid. The pressure increases, pushing the tip of the tip interface water pipe 232 to the right. The heat exchange device 2 opens and extends, and the heated material 4 has a larger heated volume. The heating area is still only the surface contact position, and the heating speed slows down. The density of the wax liquid is limited, and the heat exchange device 2 pushes to its limit, completing the first stage of preheating.

[0037] As the temperature continues to rise, the wax turns into gas, and the heat exchange device 2 then extends a second time to complete the second preheating.

[0038] After the heat flow 5 is shut off, the heat exchange device 2 cools down, and the wax changes from gas back to liquid and then back to solid. Due to the pulling force of the spring 2214, the heat exchange device returns to the closed state.

[0039] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0040] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
