Description

Technical Field

[0001] The invention relates to the technical field of chemical production, and in particular to a reaction kettle with an expansion detection function. Background Art

[0002] Reactors are a very common tool in the chemical production process. They are used to achieve the mixing functions of heating, evaporation, cooling or stirring in the process. They are widely used in the fields of petroleum, new materials, medicine, food, etc. During the mixing process such as heating and evaporation, the reactor will produce corresponding expansion deformation due to the increase in internal temperature. However, the expansion deformation cannot exceed the tolerable range of the reactor. Therefore, it is necessary to set up a corresponding expansion coefficient detection instrument to measure the expansion coefficient of the reactor.

[0003] Currently, instruments used to detect expansion coefficients are installed in reactors. During the production reaction in the reactor, a large amount of high-temperature gas is released, and most of the reaction raw materials are corrosive. The internal detection instrument components are easily damaged by high temperature and corrosion, and have a short service life. They need to be replaced frequently, which increases the user's cost of use. Summary of the invention

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0040] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0041] The reaction kettle with expansion detection function provided by the embodiment of the present invention is now described in conjunction with the accompanying drawings.

[0042] See also Figures 1 to 10A reactor with expansion detection function includes a reactor body 100, a deformation resistor winding group 200, an expansion coefficient detection component and an early warning component. A reaction chamber is provided in the reactor body 100, and liquid medicine or other raw materials react in the reaction chamber. The deformation resistor winding group 200 is tightly attached to the outer surface of the reactor body 100 along the circumferential direction, and can change the resistance value accordingly according to the expansion deformation of the reactor body 100. The expansion coefficient detection component is electrically connected to the deformation resistor winding group 200, and is used to detect the deformation signal generated by the deformation resistor winding group 200, wherein the expansion coefficient detection component may include a processor, and the processor is used to process the deformation signal of the deformation resistor winding group 200 and obtain the expansion coefficient of the reactor. The early warning component is electrically connected to the deformation resistor winding group 200 and the expansion coefficient detection component to warn the staff or take early warning protective measures.

[0043] It should be noted that the deformation resistor winding group 200 is in a tightly fitted state on the outer surface of the kettle body 100. When the reactor expands, the deformation resistor winding group 200 can be pulled and stretched, thereby changing the resistance value of the deformation resistor winding group 200, so that it has the function of detecting the expansion coefficient.

[0044] In addition, the early warning components include alarm devices and protection systems. The alarm devices include warning lights and warning bells, which provide sound and light warnings. The protection system is used to control the inlet and outlet valves and heating devices on the reactor to prevent accidents caused by continued reaction in the reactor.

[0045] Compared with the prior art, the present invention sets a deformation resistor winding group 200 on the outside of the kettle body 100 under tension. When the reactor expands, the deformation resistor winding group 200 wound on the outer surface is tensioned and stretched, elastically deformed, and the resistance value increases accordingly. The expansion coefficient detection component detects the expansion coefficient of the reactor during the production process through the change in the resistance value, and predicts the severity of the reaction in the reactor in advance. When the expansion coefficient exceeds the set warning value, the warning component reminds the staff, and the reaction in the reactor is controlled in combination with the peripheral inlet and outlet valves and machine pumps to prevent safety accidents and ensure the safe and effective implementation of the entire production process. At the same time, the deformation resistor material is resistant to high temperature and corrosion, and can be used in the production of various refined industries with various explosion-proof levels and can adapt to relatively harsh external environments.

[0046] The reactor with expansion detection function according to the present invention includes but is not limited to the following embodiments.

[0047] Example 1, see Figures 1 to 4The deformation resistor winding group 200 includes a plurality of deformation resistor wires. A coil tensioning device 300 is provided on the outer side of the kettle body 100. Each deformation resistor wire is connected to the corresponding coil tensioning device 300 one by one, and the connection terminal and output terminal of the deformation resistor wire are connected to the coil tensioning device 300, forming a deformation resistor coil 210 that is tensioned and attached to the outer side. Among them, the connection terminal and output terminal of the deformation resistor coil 210 refer to the two ends of the deformation resistor coil 210 entering and leaving the outer side of the kettle body 100. Each formed deformation resistor coil 210 is axially tensioned and arranged on the outer side along the rotation line direction, corresponding to each deformation position in the axial direction of the reactor, and can perform multi-point detection on the reactor. By analyzing the detection results of each deformation resistor coil 210, the local expansion coefficient and the overall expansion coefficient are obtained, and the expansion deformation of the reactor is accurately detected.

[0048] Furthermore, the coil tensioning device 300 includes a front housing 310, a rear housing 320 and a clamping assembly. The front housing 310 and the rear housing 320 are detachably assembled to form the outer shell of the coil tensioning device 300. The front housing 310 is provided with a wiring inlet 311, an output inlet 312 and an outlet channel 313 connected to the wiring inlet 311 and the output inlet 312. The end of the outlet channel is provided with a resistance wire outlet 314, that is, the front housing 310 is provided with three corresponding wire interfaces or wire outlets. The wiring terminal of the deformation resistance wire enters the outer shell from the wiring inlet 311, and the output terminal enters the outer shell from the output inlet 312. The wiring terminal and the output terminal are gathered in the outlet channel 313 and extend from the outlet 512 of the front housing 310 through the wiring channel. The clamping assembly is arranged on the outlet channel 313 to clamp the wiring terminal and the output terminal of the deformation resistance wire.

[0049] In this embodiment, the two ends of the deformation resistance coil 210, namely the connection end and the output end, are joined on the coil tensioning device 300, and the clamping assembly clamps the two ends to form a deformation resistance coil 210 that is tensioned and sleeved on the corresponding position of the reactor.

[0050] Specifically, the clamping assembly includes two clamping members 600, see Figure 4The clamping member 600 includes a rotating shaft 650 and a clamping wheel 610, an adjusting gear 620, a tensioning nut 630 and an adjusting cap 640 which are sequentially and coaxially arranged on the rotating shaft 650. The clamping wheel 610 is used to clamp the terminal and the output terminal, thereby controlling the length of the deformation resistance coil 210 so that the deformation resistance coil 210 can be fitted on the reactor. The tensioning nut 630 is used to fix the clamping member 600 on the shell, and the adjusting cap 640 is used to rotate the rotating shaft 650. The rotating shaft 650 includes a clamping portion, a threaded portion and an adjusting portion, the clamping wheel 610 and the adjusting gear 620 are fixedly arranged on the clamping portion, the tensioning nut 630 is threadedly connected to the threaded portion, the adjusting cap 640 is fixedly arranged on the adjusting portion, and two toothed straight grooves 800 are provided on the rear shell body 320. The two clamping frames are respectively meshed and connected to the two toothed straight grooves 800 through the adjusting gears 620 thereon. The two toothed straight grooves 800 are symmetrically arranged on the rear shell body 320 and approach each other toward one end thereof, so that when the two clamping members 600 move along the two toothed straight grooves 800, they can approach each other and gradually shrink the interval between the two clamping wheels 610, thereby clamping the terminal and the output terminal. Among them, the diameter of the clamping wheel 610 is larger than the diameter of the adjusting gear 620, so that the clamping wheel 610 is against the outside of the toothed straight groove 800. When the tensioning nut 630 moves threadably on the threaded portion, it can gradually move axially along the rotating shaft 650, shrinking the interval between the tensioning nut 630 and the clamping wheel 610, thereby clamping the clamping member 600 on the rear shell 320. Conversely, when the tensioning nut 630 is in a loosened state, the adjusting cap 640 can rotate the rotating shaft 650, and then the clamping member 600 moves on the rear shell 320 using the gear rack structure to achieve clamping of the terminal and the output terminal.

[0051] Furthermore, the two tooth-shaped straight grooves 800 are close to each other in an "eight" shape and their close ends are close to the wiring inlet 311 and the output inlet 312. When the two clamping members 600 approach each other along the two tooth-shaped straight grooves 800, the wiring terminal and the output terminal are gradually clamped, and the rotation tangent direction of the clamping member 600 is the same as the clamping direction of the wiring terminal and the output terminal, so that the two clamping members 600 gradually clamp the wiring terminal and the output terminal. The wiring terminal and the output terminal are stretched toward the outlet 512, and the deformable resistor coil 210 is tightened during the clamping process to ensure that the deformable resistor coil 210 is tightly fitted to the outside of the reactor.

[0052] Example 2, see Figures 5 to 7The deformation resistor winding group 200 includes a deformation resistor wire. The kettle body 100 is provided with two resistance wire tensioning devices 400 and at least one reversing device 700. The two resistance wire tensioning devices 400 and the reversing devices 700 are arranged in a straight line in the busbar direction on the outer surface of the reactor, and the two resistance wire tensioning devices 400 are located at both ends of the arrangement straight line, and are used to tension the two ends of the deformation resistor wire, so that the deformation resistor wire is tensioned and fits the outer surface of the kettle body 100. The deformation resistor wire passes through the two resistance wire tensioning devices 400 and the reversing devices 700, and starts to wind around the outer surface of the kettle body 100 from one of the resistance wire tensioning devices 400. After reversing by the reversing devices 700, a plurality of holding coils 220 arranged along the circumferential direction of the kettle body 100 are formed, and finally leave after being tensioned by another resistance wire tensioning device. The two resistance wire tensioning devices 400 are used to tension and fix the connection terminals and output terminals of the deformation resistor wire.

[0053] Furthermore, the resistance wire tensioning device 400 includes an inner shell 410, an outer shell and a clamping member 600. The inner shell 410 is detachably connected to the outer shell and forms the shell of the resistance wire tensioning device 400. The inner shell 410 is provided with an inlet 411, an outlet 412, a reversing inlet 413 and a reversing outlet 414. The inlet 411 and the outlet 412 are connected and are located at two edges of a diagonal corner of the inner shell 410. The reversing inlet 413 and the reversing outlet 414 are connected and are located at two edges of another diagonal corner of the inner shell 410. In this embodiment, the inner shell 410 and the outer shell are a quadrilateral structure, and the four ports on the inner shell 410 are arranged on its four sides. The clamping member 600 is arranged between the inlet 411 and the outlet 412, and clamps the connection terminal or output terminal of the deformation resistance wire on the inner shell 410. A reversing wheel 415 is arranged between the reversing inlet 413 and the reversing outlet 414, and the reversing wheel 415 is used to change the direction of the deformation resistance wire to form a clamping coil 220.

[0054] The reversing device 700 is composed of a first shell 710 and a second shell. The first shell 710 and the second shell can form a shell of the reversing device 700. The first shell 710 has a first reversing port 711, a second reversing port 712, a third reversing port 713 and a fourth reversing port 714. The first reversing port 711 and the second reversing port 712 are connected through a first reversing channel 715. The third reversing port 713 and the fourth reversing port 714 are connected through a second reversing channel 716. The first reversing channel 715 A first reversing tensioning wheel 717 is provided inside, a second reversing tensioning wheel 718 is provided inside the second reversing channel 716, the first reversing port 711 and the second reversing port 712 are arranged at two edges of one diagonal corner of the first shell 710, the third reversing port 713 and the fourth reversing port 714 are arranged at two edges of another diagonal corner of the first shell 710, the first reversing channel 715 and the second reversing channel 716 are staggered with each other, and the direction of the deformation resistance wire changes by 90° after being reversed by the first reversing tensioning wheel 717 or the second reversing tensioning wheel 718.

[0055] In this embodiment, the deformable resistor wire passes through one of the resistor wire tensioning devices 400 and is circumferentially sleeved on the kettle body 100 to form a first clamping coil 220, and is reversed by the reversing wheel 415 of the resistor wire tensioning device 400 and extends toward the adjacent reversing device 700, and continues to surround the kettle body 100 circumferentially to form a second clamping coil 220 after reversing by the reversing device 700, and repeats in sequence until the deformable resistor wire is tensioned by another resistor wire tensioning device 400 and leaves, thereby forming a plurality of clamping coils 220 sleeved on the outer surface of the kettle body 100.

[0056] The clamping member 600 in this embodiment has the same structure as the clamping member 600 in Embodiment 1, including a rotating shaft 650 and a clamping wheel 610, an adjusting gear 620, a tensioning nut 630 and an adjusting cap 640 sequentially arranged on the rotating shaft 650, which are not described in detail here. A tooth-shaped straight groove 800 adapted to the clamping member 600 is provided on the housing, and a straight tooth portion is provided in the tooth-shaped straight groove 800. The clamping member 600 moves in the tooth-shaped straight groove 800 to gradually narrow the connection channel between the access port 411 and the input port, thereby clamping and fixing the deformable resistor wire.

[0057] The deformation resistor winding set 200 in this embodiment is used to measure the overall deformation of the reactor body 100, so as to obtain the overall expansion coefficient of the reactor.

Two end tensioning devices 500 are provided on the outer surface of the kettle body 100.
