Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea drum fixing device with waste heat recovery function. Background Technology

[0002] Tea fixation is a tea-making process that uses high temperatures to destroy and deactivate the oxidase activity in fresh tea leaves, inhibit the enzymatic oxidation of tea polyphenols and other substances in the fresh leaves, evaporate some of the moisture in the fresh leaves, soften the tea leaves, make them easier to roll and shape, and at the same time remove the grassy smell and promote the formation of a good aroma.

[0003] In the prior art, such as Chinese Patent No. CN223169075U, a tea drum fixing device is disclosed, including a box body with a door hinged to one side. A heating component is provided on the outside of the box body. The heating component includes a hot air blower fixedly installed on the top of the box body. The output end of the hot air blower is connected to a connecting pipe, and the other end of the connecting pipe is connected to one side of the box body. Two first rotating shafts are rotatably connected to both sides of the inner wall of the box body. The same drum is fixedly connected to the outside of the two first rotating shafts. A stirring component is provided inside the drum, and a transmission component and a motor are provided outside the drum. A support plate is fixedly connected to the top of the inner wall of the box body. With the above structure, it is convenient for workers to perform fixing operations on tea leaves. During the fixing process, the tea leaves can be automatically turned over, so that the tea leaves can fully contact the hot air, resulting in better fixing effect and faster speed, which greatly facilitates the use of workers.

[0004] While the above solution has the advantages mentioned above, its disadvantage is that although it can heat and fix the tea leaves by starting a hot air blower and outputting hot air through a connecting pipe to the inside of the chamber, it cannot recover and utilize the residual heat from fixing the tea leaves. This results in a significant amount of heat being wasted each time the tea leaves are heated and fixed. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that, although a hot air blower can be started and output hot air is delivered to the inside of the chamber through a connecting pipe to heat and fix the tea leaves, it cannot recover and utilize the residual heat from the fixing process. This results in a significant amount of heat being wasted each time the tea leaves are heated and fixed.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a tea drum fixing device with waste heat recovery function, comprising: a fixing chamber, and further comprising: Two hollow tubes are fixedly connected to opposite sides of the inner wall of the blanching box. A blanching roller is rotatably connected to the outer surface of the two hollow tubes. A hot air blower is fixedly connected to the top of the blanching box, and an air outlet pipe is fixedly connected to the outlet end of the hot air blower. A coil is fixedly connected to the bottom of the inner wall of the blanching box. A waste heat recovery box is fixedly connected to one side of the blanching box. A preheating leak frame is provided inside the waste heat recovery box. A box cover is fixedly connected to the inner wall of the waste heat recovery box near the bottom. One end of the box cover is fixedly connected to one end of the coil. A pump is fixedly connected to one side of the blanching box. The pump's liquid-drawing end is fixedly connected to the other end of the coil, and the pump's liquid-discharging end is fixedly connected to the other end of the coil.

[0007] Preferably, a gear one is fixedly connected to one side of the blanching drum, and the gear one is rotatably connected to one of the hollow tubes. A rotating rod is rotatably connected to the other side of the blanching box. A gear two is fixedly connected to one end of the rotating rod, and the gear two meshes with the gear one. A motor is fixedly connected to the other side of the blanching box, and the output end of the motor is fixedly connected to the other end of the rotating rod.

[0008] Preferably, the two hollow tubes are slidably connected to each other with a sliding rod, and a plurality of stirring rods are fixedly connected at equal intervals to the outer surface of the sliding rod.

[0009] Preferably, a groove is formed on the outer surface of the hollow tube, a slide bar is slidably connected inside the groove, the slide bar is fixedly connected to the slide rod, a pulley is fixedly connected to the top of the slide bar, and an arc-shaped block is fixedly connected to the other side of the blanching roller.

[0010] Preferably, the slide rod is slidably connected to the waste heat recovery box, the slide rod is fixedly connected to the preheating leakage frame, and a spring is provided on the outer surface of the slide rod, the spring being fixedly connected to the waste heat recovery box and the preheating leakage frame respectively.

[0011] Preferably, the first coil and the second coil are connected, and the top of the waste heat recovery box is movably fitted with a box cover via a hinge.

[0012] Preferably, the outer surface of the blanching roller is detachably covered with a cylinder cover, and two doors are symmetrically and movable on the front side of the blanching box via hinges.

[0013] Preferably, a temperature sensor is fixedly connected to the top of the blanching chamber, and one end of the temperature sensor extends into the interior of the blanching chamber.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 0. This utility model utilizes the liquid inside coil two to absorb excess heat from the blanching chamber. A controller then activates a pump, drawing liquid from coil two and transferring it to coil one. The liquid in coil one is then transferred to coil two. This liquid circulation transfers the absorbed heat to a waste heat recovery tank, heating its interior and increasing its temperature. This allows for the recovery and reuse of waste heat from the blanching chamber, preheating the tea leaves inside the preheating perforation frame. This ensures the tea leaves have a certain initial temperature, reducing the heat required for subsequent blanching and minimizing heat waste.

[0015] 1. This utility model utilizes the rotation of the fixing drum to drive the rotation of the arc-shaped block, causing the arc surface of the arc-shaped block to contact the arc surface of the pulley and apply a thrust to the pulley. This causes the pulley to drive the slide bar to slide to one side along the inside of the slide groove, simultaneously driving the slide rod to slide to one side along the inside of the hollow tube. Simultaneously, this causes the preheating sprue frame and stirring rod to move, stretching the spring. When the thrust of the arc-shaped block on the pulley disappears, the spring's restoring force allows the preheating sprue frame, slide rod, and stirring rod to move to the other side. This process is repeated, allowing for simultaneous and appropriate stirring of the tea leaves being fixed inside the fixing drum and shaking of the tea leaves inside the preheating sprue frame. This ensures that the tea leaves being fixed and those awaiting fixing are heated evenly, guaranteeing the effectiveness of fixing and preheating. Attached Figure Description

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Examples, such as Figure 1-5 As shown, this utility model provides a tea drum blanching device with waste heat recovery function, including: a blanching box 1, and two hollow tubes 4, which are respectively fixedly connected to opposite sides of the inner wall of the blanching box 1. A blanching drum 401 is rotatably connected to the outer surface of the two hollow tubes 4. A hot air blower 101 is fixedly connected to the top of the blanching box 1. An air outlet pipe 104 is fixedly connected to the air outlet end of the hot air blower 101. A coil 302 is fixedly connected to the bottom of the inner wall of the blanching box 1. A waste heat recovery box 2 is fixedly connected to one side of the blanching box 1. A preheating leak frame 412 is provided inside the waste heat recovery box 2. A box cover 201 is fixedly connected to the inner wall of the waste heat recovery box 2 near the bottom. One end of the box cover 201 is fixedly connected to one end of the coil 302. A pump body 3 is fixedly connected to one side of the blanching box 1. The liquid suction end of the pump body 3 is fixedly connected to the other end of the coil 302. The liquid discharge end of the pump body 3 is fixedly connected to the other end of the coil 301.

[0021] Furthermore, such as Figure 1-5As shown, a gear 402 is fixedly connected to one side of the fixing drum 401. The gear 402 is rotatably connected to one of the hollow tubes 4. A rotating rod 404 is rotatably connected to the other side of the fixing box 1. A gear 405 is fixedly connected to one end of the rotating rod 404. The gear 405 meshes with the gear 402. A motor 403 is fixedly connected to the other side of the fixing box 1. The output end of the motor 403 is fixedly connected to the other end of the rotating rod 404. The motor 403 is started by the controller, so that its output shaft drives the rotating rod 404 and the gear 405 to rotate. Then, under the action of the meshing of the gear 405 and the gear 402, the gear 402 can drive the fixing drum 401 to rotate, thereby fixing the tea leaves.

[0022] Furthermore, such as Figure 1-5 As shown, two hollow tubes 4 are slidably connected to the inside of a slide rod 407, and multiple stirring rods 406 are fixedly connected at equal intervals on the outer surface of the slide rod 407. With the above arrangement, when the slide rod 407 slides back and forth along the inside of the hollow tube 4, it can drive the stirring rods 406 to move back and forth, and in conjunction with the rotation of the fixing drum 401, the tea leaves can be stirred and turned in a better way.

[0023] Furthermore, such as Figure 1-5 As shown, a groove 408 is provided on the outer surface of the hollow tube 4. A slide bar 409 is slidably connected inside the groove 408. The slide bar 409 is fixedly connected to the slide rod 407. A pulley 410 is fixedly connected to the top of the slide bar 409. An arc-shaped block 411 is fixedly connected to the other side of the blanching roller 401. By rotating the blanching roller 401, the arc-shaped block 411 can be driven to rotate, so that the arc surface of the arc-shaped block 411 contacts the arc surface of the pulley 410 and applies a thrust to the pulley 410, so that the pulley 410 drives the slide bar 409 to slide to one side along the inside of the groove 408, and simultaneously drives the slide rod 407 to slide to one side along the inside of the hollow tube 4.

[0024] Furthermore, such as Figure 1-5 As shown, the slide rod 407 is slidably connected to the waste heat recovery box 2 and fixedly connected to the preheating leakage frame 412. A spring 413 is provided on the outer surface of the slide rod 407. The spring 413 is fixedly connected to the waste heat recovery box 2 and the preheating leakage frame 412 respectively. Under the reset force of the spring 413, a pulling force can be applied to the preheating leakage frame 412, causing the preheating leakage frame 412 to move towards the side of the blanching box 1, and synchronously driving the slide rod 407 to move in the same direction.

[0025] Furthermore, such as Figure 1-5 As shown, coil 1 301 and coil 2 302 are connected. The top of the waste heat recovery box 2 is hinged and fitted with a box cover 201, which provides a certain sealing effect.

[0026] Furthermore, such as Figure 1-5 As shown, a cover 414 is detachably installed on the outer surface of the fixing drum 401. Two doors 102 are symmetrically installed on the front side of the fixing box 1 via hinges. By opening the cover 414, it is convenient to take out the fixed tea leaves or put in the tea leaves to be fixed. The setting of the doors 102 reduces the loss of heat inside the fixing box 1.

[0027] Furthermore, such as Figure 1-5 As shown, a temperature sensor 103 is fixedly connected to the top of the blanching chamber 1. One end of the temperature sensor 103 extends into the interior of the blanching chamber 1. The temperature sensor 103 facilitates the detection of the temperature inside the blanching chamber 1.

[0028] Working principle: In use, the chamber door 102 is opened, then the cylinder cover 414 is opened, and the tea leaves to be blanched are poured into the blanching drum 401. The cylinder cover 414 and the chamber door 102 are closed in sequence, then the chamber cover 201 is opened, and the tea leaves to be blanched are placed in the preheating perforation frame 412. The chamber cover 201 is then closed. Next, the hot air blower 101 is started by controlling the controller, which delivers hot air into the blanching chamber 1 through the air outlet pipe 104. Simultaneously, the motor 403 is started by controlling the controller, and its output shaft drives the rotating rod 404. When gear 2 405 rotates, the meshing action of gear 2 405 and gear 1 402 causes gear 1 402 to drive the fixing drum 401 to rotate, fixing the tea leaves. Liquid is added inside coil 2 302 and coil 1 301. The liquid inside coil 2 302 absorbs the excess heat inside the fixing box 1. Then, the controller controls the pump 3 to start, so that its liquid extraction end draws out coil 2 302 and delivers the liquid to coil 1 301, and then delivers the liquid in coil 1 301 to coil 2 302. By circulating the liquid in this way, the heat absorbed by the liquid can be transferred to the waste heat recovery box 2 to heat the interior of the waste heat recovery box 2, raising the internal temperature. This allows for the recovery and utilization of the waste heat inside the fixing box 1, preheating the tea leaves to be fixed inside the preheating perforation frame 412. This ensures that the tea leaves have a certain initial temperature, reducing the heat consumed in the subsequent fixing process and minimizing heat waste. Simultaneously, the rotation of the fixing roller 401 drives the arc-shaped block 411 to rotate, causing the arc surface of the arc-shaped block 411 to contact the arc surface of the pulley 410 and apply a thrust to the pulley 410, causing the pulley 410 to drive the sliding strip. 409 slides to one side along the inside of the slide groove 408, simultaneously driving the slide rod 407 to slide to one side along the inside of the hollow tube 4, simultaneously driving the preheating vent frame 412 and the stirring rod 406 to move, causing the spring 413 to stretch. When the thrust of the arc block 411 on the pulley 410 disappears, the preheating vent frame 412, slide rod 407 and stirring rod 406 can be moved to the other side by the restoring force of the spring 413. This is repeated, so that the tea being processed inside the processing drum 401 can be properly stirred and the tea inside the preheating vent frame 412 can be shaken at the same time, so that the tea being processed and the tea to be processed are heated evenly, ensuring the effect of tea processing and preheating.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
