Description

Technical Field

[0001] The present invention relates to the technical field of plate heat exchange equipment, and more specifically, to an energy-saving heat exchange device for drying traditional Chinese medicine with self-inductive temperature control. Background Art

[0002] Self-inductive temperature control for energy-saving heat exchange in the drying of traditional Chinese medicine is an efficient, intelligent and environmentally friendly drying technology for traditional Chinese medicine. Combined with heat exchange equipment, it can monitor and adjust the temperature in the drying process in real time, ensure that the traditional Chinese medicine is dried under the best temperature conditions, achieve the effect of energy-saving heat exchange, and can effectively maintain the active ingredients and medicinal effects of the traditional Chinese medicine, avoiding the decline of the quality of the medicinal materials caused by too high or too low temperature.

[0003] At present, when using a plate heat exchanger for drying traditional Chinese medicine, it is found that impurities and sediments contained in the water, such as calcium, magnesium and other ions, accumulate in the pipeline as the water flows. Affected by temperature, flow rate and the surrounding environment, these salts are easily precipitated from the water at high temperature and adhere to the surface of the plate of the plate heat exchanger, forming scale that is difficult to remove;

[0004] To solve the above problems, a self-inductive temperature control energy-saving heat exchange device for drying traditional Chinese medicine is proposed in this application. Summary of the Invention

[0005] The purpose of the present invention is to provide a self-inductive temperature control energy-saving heat exchange device for drying traditional Chinese medicine, which prevents the formation of scale, delays leakage and is convenient for maintenance.

[0006] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0007] A self-inductive temperature control energy-saving heat exchange device for drying traditional Chinese medicine includes a heat exchanger, a heat exchange unit and the plates inside it, and also includes a transmission pipe and the first connecting pipe and the second connecting pipe inside it;

[0008] A shifting plate is located on one side of the plate, and is used to move back and forth to clean the impurities on its plate surface. A pulling rope is provided at the upper end of the shifting plate, which passes through the extension sleeve on the outer circle area on one side of the plate in the front and back direction. There are two upper and lower limiting shafts inside the heat exchanger for driving the shifting plate to move back and forth. A liquid inlet is opened on one side of the shifting plate, and a liquid spraying port is opened on the side adjacent to the plate, which is communicated with the liquid inlet, and is used to make the water flow spray onto the plate to form cleaning;

[0009] A sealing part is located on one side of the extension sleeve, and is used to seal the gap between the extension sleeve and the adjacent plate. An extrusion block is provided at the upper end of the shifting plate for pressing against the convex pad inside the sealing part to achieve the function of blocking the leakage point;

[0010] Conical, located inside the first connecting pipe, used to intercept impurities in water and guide them to the outer ring, and an outer ring frame is provided in the outer ring area of the conical shape. A filter bag is installed inside to collect impurities and allow water to flow back to the second connecting pipe;

[0011] The rotating frame is rotatably installed on the convex seat outside the first connecting pipe, and the rotating frame and the convex seat are fixed at different angles by a positioning pin. It is used to adjust the angles of the inner dial and the inner ring frame inside it, and make the mesh holes of the dial and the inner ring frame misaligned with the mesh holes of the outer ring frame and the partition on one side adjacent to the conical shape to achieve a sealing effect. At this time, disassembling the jacket and the gasket inside between the first connecting pipe and the second connecting pipe can achieve the effect of directly cleaning or replacing the filter bag without stopping the machine.

[0012] Advantages of the present invention:

[0013] Through the addition of the baffle plate in the present invention, combined with the transmission of the pull rope driven by the limiting shaft, the baffle plate can move back and forth repeatedly between adjacent plates. During this period, the water inlet and the liquid spraying port cooperate to form a water flow spraying onto the surface of the plates, which can not only remove the adsorbed impurities to prevent scaling and hardening, but also drive the continuous flow of particles in the water, facilitating the discharge to achieve the effect of continuously purifying the water quality inside the heat exchange unit;

[0014] While the baffle plate moves back and forth in the present invention, it can also temporarily hold the loose part of the convex pad by the extrusion block to achieve the effect of delaying leakage, which is convenient for the staff to repair and handle in time;

[0015] Through the addition of the conical shape in the present invention, the impurities in the water can be directly intercepted and discharged into the filter bag for storage, and the automatic cleaning is formed by using its conical structure combined with the transmission of water flow to achieve the effect of long-term interception of impurities, so as to prevent the impurities from being transmitted with the water circulation and ensure the long-term use quality of the circulating water;

[0016] After a certain amount of impurities are stored in the present invention, the angles of the rotating frame can be adjusted to make the mesh holes of the dial and the inner ring frame misaligned with the mesh holes of the partition and the outer ring frame to achieve a sealing effect, so that water cannot enter. Then, the jacket can be directly disassembled to replace or clean the filter bag. During this period, the normal operation of the equipment is maintained, the working difficulty is reduced, and the operation efficiency of the equipment is maintained, making it more convenient to use.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figure 1 - Figure 8 As shown, the present invention provides a self - sensing temperature - controlled energy - saving heat - exchange device for drying Chinese medicinal materials, including a heat exchanger 1, a heat - exchange unit 2 and the plate fins 21 inside it, and also including a transmission pipe 5 and the first connecting pipe 51 and the second connecting pipe 52 inside it

[0039] A baffle 6, located on one side of the plate fin 21, is used to move back and forth to clean the impurities on its plate surface. A pulling rope 63 is provided at the upper end of the baffle 6, which passes through the extension sleeve 22 extending through the outer - ring area on one side of the plate fin 21. There are two upper and lower limiting shafts 42 inside the heat exchanger 1 for driving the baffle 6 to move back and forth. A liquid inlet 621 is provided on one side of the baffle 6, and a liquid spraying port 622 is provided adjacent to one side of the plate fin 21 and is communicated with the liquid inlet 621 for spraying water onto the plate fin 21 to form cleaning;

[0040] A sealing part 3, located on one side of the extension sleeve 22, is used to seal the gap between the extension sleeve 22 and the adjacent plate fin 21. An extrusion block 66 is provided at the upper end of the baffle 6 for pressing against the convex pad 311 inside the sealing part 3 to achieve the function of blocking the leakage point;

[0041] A conical shape 55, located inside the first connecting pipe 51, is used to intercept impurities in the water and guide them to the outer circle. An outer ring frame 551 is provided in the outer - ring area of the conical shape 55, and a filter bag 56 is installed inside for collecting impurities and enabling the water to flow back to the second connecting pipe 52;

[0042] The rotary frame 54 is rotatably mounted on the convex seat 511 outside the first connecting pipe 51, and the rotary frame 54 and the convex seat 511 are fixed at different angles by the positioning pin 541, which is used to adjust the angles of the internal dial 542 and the inner ring frame 543, and to misalign the meshes of the dial 542 and the inner ring frame 543 with the meshes of the outer ring frame 551 and the partition plate 552 on the side adjacent to the cone 55, so as to achieve the sealing effect. At this time, by removing the jacket 53 between the first connecting pipe 51 and the second connecting pipe 52 and the gasket 531 inside it, the effect of directly cleaning or replacing the filter bag 56 without stopping the machine can be achieved;

[0043] This embodiment provides a plate heat exchanger that can prevent fouling on the plate surface. By the forward and backward sliding of the baffle 6 between adjacent plates 21 and combined with the guiding of the liquid inlet 621, a water flow is formed to continuously wash the plates 21 in real time. This can not only achieve the cleaning effect of removing the adsorbed particles, but also drive the particles in the water to continuously flow to prevent them from adsorbing on the plates 21, forming a double cleaning effect. Moreover, by the movement of the baffle 6, the extrusion block 66 can also be driven to temporarily press against the convex gasket 311 at the leakage position to achieve the effect of delaying leakage, which is convenient for the maintenance of the staff; In addition, the discharged particle impurities will be intercepted and guided by the cone 55, so that they are directly collected in the filter bag 56 to prevent continuous pollution of the water flow channel following the circulating water. Finally, in the state of the equipment not stopping, by adjusting the mesh positions of the dial 542 and the inner ring frame 543 to misalign them with the meshes of the outer ring frame 551 and the partition plate 552, the jacket 53 can be directly removed to take out the filter bag for cleaning or replacement, so as to maintain the stable filtering function of the equipment for long-term use.

[0044] As Figure 1 - Figure 5 As shown in the figure, rotary motors 41 are provided at the top of both ends of the heat exchanger 1, which are combined with the limit shafts 42 to form a transmission unit 4. Furthermore, by means of the convex shaft 421 on the outside of the limit shaft 42 and the arc-shaped groove 422 on its outer ring, the pull rope 63 can be squeezed to increase the frictional resistance, and combined with the docking of the convex block 612 and the side groove 611 between adjacent plates 21, the rotation of the rotary motor 41 can drive each pull rope 63 to transmit simultaneously, achieving the effect of synchronous movement of each baffle 6; Further, tooth discs 43 are provided at the opposite ends of the rotary motor 41 and the limit shaft 42 and are meshed with each other. Only one end of the upper and lower two limit shafts 42 is connected with a tooth disc 43, and the other end is provided with a fixing frame 44 fixedly installed on the heat exchanger 1. The fixing frame 44 is located outside the tooth disc 43 for rotatably installing the limit shaft 42;

[0045] Among them, the side groove 611 is located on the right side of the baffle 6 on the right side of the plate 21, the convex block 612 is located on the left side of the baffle 6 on the left side of the plate 21, and sealing cylinders 221 are provided at the positions near the upper ends of both ends of the extension sleeve 22 for docking the pull rope 63 and forming a seal;

[0046] In addition, sliders 64 are provided at both upper and lower ends of the paddle plate 6 to be slidably mounted in the slide grooves 23 on both sides of the plate 21. Positioning grooves 65 are provided inside the sliders 64 and balls 651 are installed thereon to reduce the resistance of the paddle plate 6 when it slides, thereby preventing the paddle plate 6 from tilting and getting stuck when it slides back and forth.

[0047] like Figure 3 and Figure 5 As shown, a sealing gasket 31 is provided on the inner side of the sealing portion 3, which is used to install the convex gasket 311 and to seal the gap between the extension sleeve 22 and the adjacent plate 21. When the convex gasket 311 is squeezed, it shrinks inward to achieve the effect of strengthening the sealing.

[0048] like Figure 1 and Figure 7 As shown, a guide seat 512 is provided inside the first connecting pipe 51 for collecting water flow, so that the water flow is directly transmitted to the central area of the cone 55, and then the conical structure combined with the fluidity of the water flow can automatically form a flushing so that the impurities flow to the outer circle area for easy collection;

[0049] A reinforcing rib 521 is provided at one end of the guide seat 512 and is connected to the inner wall of the second connecting tube 52 , so as to enhance the structural stability between the first connecting tube 51 and the second connecting tube 52 .

[0050] like Figure 8 As shown, a connecting frame 544 is provided on one side of the rotating frame 54 for mounting the dial 542 and for sealing the gap between the jacket 53 and the first connecting pipe 51 .

[0051] like Figure 9 As shown, the open end of the filter bag 56 is provided with a plug plate 561 connected to the clamp seat 5421 on the side of the dial 542, and the outer side of the plug plate 561 is provided with a triangular clamping block 562 clamped to the clamping groove 5422 on the inner side of the clamp seat 5421, so as to achieve the effect of convenient assembly and disassembly.

[0052] It can be understood that the plate heat exchanger of the present invention can clean internal impurities in real time, preventing them from being adsorbed for a long time to form scale, and promote the discharge of impurities, and then filter and collect them during discharge, so that they cannot circulate with water, thereby achieving the effect of continuously purifying water quality.
