Description

Technical Field

[0001] This utility model belongs to the field of water-reducing agent production technology, and in particular relates to a heating reaction device for producing water-reducing agents. Background Technology

[0002] In the production of chemical products such as water-reducing agents, heating reaction is a key process step. Traditional heating reaction devices typically have heating elements (such as heating plates and heating jackets) fixedly installed on the outer wall of the reaction vessel (such as the reactor vessel). When rapid heating is required in the initial stage of the reaction, or when only local areas need to be kept warm during the reaction, fixed heating cannot flexibly adjust the effective heating area according to the actual process requirements, resulting in poor adaptability. Utility Model Content

[0003] The purpose of this invention is to provide a heating reaction device for producing water-reducing agents. By setting up heating components, specifically, the lower heating plate rapidly melts the solid raw material at the bottom of the heating chamber at high temperature, while the upper heating plate is used at a low temperature to prevent solvent evaporation, segmented temperature control is achieved. When it is necessary to adjust the temperature control area, the distance between the two heating plates is adjusted by using a drive mechanism to drive the slider and heating plate to adjust the distance between the two heating plates, thus flexibly adjusting the heating area. This solves the problem that the fixed heating of existing heating reaction devices cannot flexibly adjust the effective heating area according to actual process requirements, resulting in poor adaptability.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a heating reaction device for producing water-reducing agents, comprising a sleeve, a heating assembly, and an automatic pressure relief assembly. The sleeve includes a heating chamber, which is fixedly connected inside the sleeve. An inlet is fixedly connected to the top of the heating chamber, and an outlet is fixedly connected to the bottom of the heating chamber. The heating assembly is installed on the outer surface of the heating chamber for heating the chamber. The heating assembly includes: The heating plate is provided in two parts. The heating plate is slidably connected to the outer surface of the heating chamber. Slider is fixedly connected to the left and right sides of the heating plate. A driving mechanism is used to drive the slider and heating plate to slide on the outer surface of the heating chamber. The driving mechanism includes two lead screws with threads on their outer surfaces arranged in opposite directions. The lead screws are rotatably connected inside the sleeve. The outer surfaces of the lead screws are threadedly connected to the inner surface of the slider. A gear one is fixedly connected to the top of the lead screws. A gear ring is rotatably connected to the top of the heating chamber. A gear two is rotatably connected to the back of the top of the sleeve. The outer surface of the gear ring meshes with the outer surfaces of gear one and gear two, respectively. A motor two is fixedly connected to the top of the sleeve. The bottom output end of motor two is fixedly connected to the top of gear two. The automatic pressure relief assembly is installed on the top of the heating element and is used for automatic pressure relief inside the heating element.

[0005] Furthermore, a guide rail is provided inside the sleeve, and the inner wall of the guide rail is slidably connected to the outer surface of the slider.

[0006] Furthermore, a shaft is rotatably connected inside the heating chamber, and a stirring blade is fixedly connected to the outer surface of the shaft. A motor is fixedly connected to the top of the heating chamber, and the bottom output end of the motor is fixedly connected to the top of the shaft via a coupling.

[0007] Furthermore, a heating wire is fixedly connected inside the shaft.

[0008] Furthermore, a flow guide groove is fixedly connected to the bottom of the heating element, and a valve is fixedly connected to the bottom of the flow guide groove.

[0009] Furthermore, the automatic pressure relief assembly includes: The pressure relief port is fixedly connected to the top of the heating element. A support block is fixedly connected inside the pressure relief port. Two telescopic rods are fixedly connected to the top of the support block. Springs are sleeved on the outer surface of the telescopic rods. A pressure relief valve is fixedly connected to the top of two telescopic rods, and the bottom of the pressure relief valve is inserted into the inner wall of the pressure relief port.

[0010] Furthermore, the automatic pressure relief assembly also includes an activated carbon adsorption box, which is located on the left side of the sleeve. A connecting pipe is fixedly connected to the top of the activated carbon adsorption box, and the side of the connecting pipe away from the activated carbon adsorption box is fixedly connected to the outer surface of the pressure relief port. An exhaust port is fixedly connected to the left side of the activated carbon adsorption box.

[0011] This utility model has the following beneficial effects: 1. This utility model sets up a heating component, specifically a lower heating plate that rapidly melts the solid raw material at the bottom of the heating chamber at high temperature, and an upper heating plate that is at a low temperature to prevent solvent evaporation, thereby achieving segmented temperature control. When it is necessary to adjust the temperature control area, the driving mechanism is used to drive the slider and heating plate to move and adjust the distance between the two heating plates, so as to flexibly adjust the heating area and improve the adaptability of the device.

[0012] 2. This utility model incorporates an automatic pressure relief component. Under normal circumstances, the pressure relief valve is closed due to the spring force. When the internal pressure of the heating tank is too high, the pressure exceeds the spring force, causing the pressure relief valve to be lifted and the gas to be discharged through the pressure relief port. This prevents excessive pressure from causing equipment damage or safety accidents and ensures production safety.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.

[0018] Please see Figures 1-5 As shown, this utility model has the following three specific embodiments.

[0019] Example 1 This utility model relates to a heating reaction device for producing water-reducing agents, comprising a sleeve 1, a heating assembly 2, and an automatic pressure relief assembly 3. The sleeve 1 includes a heating chamber 11, which is fixedly connected inside the sleeve 1. An inlet 111 is fixedly connected to the top of the heating chamber 11, and an outlet 112 is fixedly connected to the bottom of the heating chamber 11. The heating assembly 2 is installed on the outer surface of the heating chamber 11 and is used for heating the heating chamber 11. The heating assembly 2 includes: Heating plate 21, the number of heating plates 21 is set to two, the heating plate 21 is slidably connected to the outer surface of the heating chamber 11, and sliders 211 are fixedly connected to the left and right sides of the heating plate 21. A drive mechanism is used to drive the slider 211 and the heating plate 21 to slide on the outer surface of the heating chamber 11. The drive mechanism includes two lead screws 212, the threads on the outer surfaces of the two lead screws 212 are arranged in two opposite directions, the lead screws 212 are rotatably connected inside the sleeve 1, the outer surface of the lead screws 212 is threadedly connected to the inner surface of the slider 211, a gear 213 is fixedly connected to the top of the lead screws 212, a gear ring 214 is rotatably connected to the top of the heating chamber 11, a gear 215 is rotatably connected to the back of the top of the sleeve 1, the outer surface of the gear ring 214 meshes with the outer surfaces of the two gears 213 and the gear 215 respectively, a motor 216 is fixedly connected to the top of the sleeve 1, and the bottom output end of the motor 216 is fixedly connected to the top of the gear 215. The automatic pressure relief assembly 3 is installed on the top of the heating tank 11 for automatic pressure relief inside the heating tank 11.

[0020] like Figures 1-2 As shown, by setting up heating component 2, specifically, the lower heating plate 21 rapidly melts the solid raw material at the bottom of the heating chamber 11 at high temperature, while the upper heating plate 21 is used at low temperature to prevent solvent evaporation, segmented temperature control is achieved. When it is necessary to adjust the temperature control area, the driving mechanism is used to drive the slider 211 and the heating plate 21 to move and adjust the distance between the two heating plates 21, flexibly adjusting the heating area and improving the adaptability of the device.

[0021] The sleeve 1 has a guide rail 22 inside, and the inner wall of the guide rail 22 is slidably connected to the outer surface of the slider 211.

[0022] The guide rail 22 ensures the stability and accuracy of the slider 211 and heating plate 21 during the sliding process, prevents deviation or jamming, ensures good contact between the heating plate 21 and the outer wall of the heating chamber 11, and improves the reliability of equipment operation. Example 2 The difference from Embodiment 1 is that this embodiment discloses the internal structure of the heating element 11: The heating tank 11 is rotatably connected to a shaft 12, and a stirring blade 121 is fixedly connected to the outer surface of the shaft 12. A motor 122 is fixedly connected to the top of the heating tank 11, and the bottom output end of the motor 122 is fixedly connected to the top of the shaft 12 via a coupling.

[0023] A heating wire 123 is fixedly connected inside the shaft 12.

[0024] A flow guide groove 13 is fixedly connected to the bottom of the heating element 11, and a valve 131 is fixedly connected to the bottom of the flow guide groove 13.

[0025] like Figures 3-4 As shown, the motor 122 drives the shaft 12 and the stirring blade 121 to rotate, which promotes the mixing of raw materials and ensures uniform heating; the heating wire 123 can provide auxiliary heating when the temperature of the heating chamber 11 is insufficient; the remaining material flows to the bottom through the guide channel 13, and the remaining material can be discharged with the valve 131 for easy cleaning.

[0026] Example 3 The difference from Embodiment 2 is that this embodiment discloses how the automatic pressure relief component 3 achieves automatic pressure relief: Automatic pressure relief component 3 includes: Pressure relief port 31 is fixedly connected to the top of heating tank 11. A support block 311 is fixedly connected inside the pressure relief port 31. Two telescopic rods 312 are fixedly connected to the top of the support block 311. Springs 313 are sleeved on the outer surface of the telescopic rods 312. The pressure relief valve 32 is fixedly connected to the top of the two telescopic rods 312, and the bottom of the pressure relief valve 32 is inserted into the inner wall of the pressure relief port 31.

[0027] like Figure 5 As shown, by setting up the automatic pressure relief component 3, under normal circumstances, the pressure relief valve 32 is in the closed state due to the elastic force of the spring 313. When the internal pressure of the heating tank 11 is too high, the pressure is greater than the elastic force, which pushes the pressure relief valve 32 up, and the gas is discharged through the pressure relief port 31, preventing the equipment from being damaged or a safety accident caused by excessive pressure, and ensuring production safety.

[0028] The automatic pressure relief assembly 3 also includes an activated carbon adsorption box 33, which is located on the left side of the sleeve 1. A connecting pipe 331 is fixedly connected to the top of the activated carbon adsorption box 33. The side of the connecting pipe 331 away from the activated carbon adsorption box 33 is fixedly connected to the outer surface of the pressure relief port 31. An exhaust port 332 is fixedly connected to the left side of the activated carbon adsorption box 33.

[0029] The gas discharged from the pressure relief port 31 is introduced into the activated carbon adsorption box 33 through the connecting pipe 331, which can effectively adsorb harmful substances, odors or volatile organic compounds in the gas, greatly reducing the environmental pollution caused by direct emission of waste gas and meeting environmental protection requirements.

[0030] A specific application of this embodiment is as follows: During use, the raw material is injected through the feed inlet 111. Motor 122 is started, driving the shaft 12 and stirring blades 121 to rotate, promoting mixing of the raw material. The lower heating plate 21 rapidly melts the solid raw material at the bottom of the heating chamber 11 at high temperature, while the upper heating plate 21 is kept at a low temperature to prevent solvent evaporation, achieving segmented temperature control. When the temperature control zone needs adjustment, motor 216 is started, driving the gear ring 214 to rotate at the top of the sleeve 1 via gear 215. The gear ring drives two gears 213 to rotate simultaneously in opposite directions. Since the two lead screws 212 have opposite threads, and the threads on the outer surface of the lead screws 212 are also set in two opposite directions, the lead screws 212 drive the two heating plates 21 to rotate simultaneously in opposite directions via the slider 211. The direction of movement adjusts the distance between the two heating plates 21. While the heating plates 21 move, the slider 211 slides on the inner wall of the guide rail 22. The guide rail 22 provides a stable motion trajectory for the movement of the heating plates 21, preventing the heating plates 21 from deflecting. When the internal temperature of the heating tank 11 is insufficient, the heating wire 123 inside the shaft 12 can be used for auxiliary heating. Under normal circumstances, the pressure relief valve 32 is closed due to the elastic force of the spring 313. When the internal pressure of the heating tank 11 is too high, the pressure exceeds the elastic force, pushing the pressure relief valve 32 up. The gas enters the activated carbon adsorption box 33 through the pressure relief port 31 and the connecting pipe 331. After being purified by the activated carbon adsorption box 33, it is discharged from the exhaust port 332, avoiding direct emission and environmental pollution.
