Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and more specifically, to a radiant tube type tea grinder. Background Technology

[0002] In the tea-making process, there is a very important step: after the green tea leaves are steamed to kill the greenness, they need to be roasted in a tea-making oven to develop a special roasted aroma (oven aroma) and to better preserve the original green color of the raw materials. Color preservation and oven aroma are the two most important indicators of a tea-making oven.

[0003] Traditional tea grinders typically use brick-type grinders. A large burner heats the cast iron until it's red-hot, and the infrared radiation and convection emitted by the red-hot iron dry the tea leaves. The tea leaves circulate 4-5 layers inside the grinder via a conveyor belt. The disadvantages of this type of tea grinder are:

[0004] 1. It requires digging an underground foundation pit, which is difficult to construct, takes a long time, and is prone to water leakage;

[0005] 2. Due to its large size, the installation needs to be carried out in two stages: the frame needs to be built on site, and the later stages of the project will be installed after the walls are demolished.

[0006] 3. Once installed, the tea grinder cannot be moved; disassembling it renders it unusable.

[0007] 4. High energy consumption: Due to the large combustion chamber space, a large burner is required to heat the cast iron to a red-hot state. To avoid scorching the tea leaves, the large area of ​​red-hot cast iron cannot be placed too close to the tea leaves, resulting in a significant waste of fuel energy.

[0008] Therefore, a new solution is needed to address the above problems. Utility Model Content

[0009] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a radiant tube tea grinder.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A radiant tube type tea grinder includes a furnace body and a first conveyor belt, a second conveyor belt, and a third conveyor belt installed inside the furnace body. The first, second, and third conveyor belts are arranged from bottom to top, and each of them is partially exposed outside the furnace body. Multiple sets of infrared heat radiation modules are arranged side by side along the length of the furnace body. Each infrared heat radiation module is independent of the others. Each set of infrared heat radiation modules includes an upper cast iron pipe and a lower cast iron pipe for the flow of high-temperature gas. The upper cast iron pipe is horizontally located between the second and third conveyor belts, and the lower cast iron pipe is horizontally located between the upper and lower mesh belts of the first conveyor belt. The flow direction of the high-temperature gas in the upper and lower cast iron pipes is perpendicular to the conveying direction of the tea grinder.

[0012] Furthermore, both the upper and lower cast iron pipes have a serpentine structure, and the upper and lower cast iron pipes are connected by a connecting pipe.

[0013] Furthermore, both ends of the upper cast iron pipe are exposed to the second and third conveyor belts, while both ends of the lower cast iron pipe are exposed to the first conveyor belt.

[0014] Furthermore, each infrared thermal radiation module is equipped with a burner, which includes a housing with a blower installed. The blower's outlet is connected to a lower cast iron pipe. A gas interface is installed on the outer wall of the housing, and an air inlet pipe is installed on the gas interface. The end of the air inlet pipe penetrates the housing and extends into the inner cavity of the housing. A nozzle is installed at the end of the air inlet pipe. An ignition needle is installed in the inner cavity of the housing. A controller is installed on the outer wall of the housing, and the controller is electrically connected to the blower and the ignition needle.

[0015] Furthermore, the upper cast iron pipe is fixedly installed on the frame of the furnace body, and the lower cast iron pipe is fixedly installed on the mounting bracket. The mounting bracket is installed inside the furnace body and can move up and down.

[0016] Furthermore, the mounting bracket is equipped with a height adjustment mechanism for adjusting the vertical height of the mounting bracket.

[0017] Furthermore, the mounting frame has a rectangular structure, and a set of height adjustment mechanisms is installed at each of the four corners of the mounting frame. The height adjustment mechanism includes a vertically arranged screw that is threadedly connected to the furnace frame. One end of the screw is located inside the furnace and rotatably connected to the mounting frame, and the other end of the screw is located outside the furnace and fixedly installed with a first nut. The screw is threadedly connected with a second nut, which is located inside the furnace and abuts against the furnace frame.

[0018] Furthermore, both sides of the first conveyor belt are exposed outside the furnace body. A first tea hood is installed above the right side of the first conveyor belt, and a tea machine is installed below the left side of the first conveyor belt. The left side of the third conveyor belt is exposed outside the furnace body, and a second tea hood is installed above the left side of the third conveyor belt. The tea machine is connected to the second tea hood via a pipe. The left side of the second conveyor belt is exposed outside the furnace body.

[0019] Furthermore, the lower mesh belt of the first conveyor belt is exposed outside the furnace body and located below the furnace body.

[0020] The beneficial effects of this utility model are:

[0021] 1. In this utility model, by setting multiple sets of infrared heat radiation modules arranged side by side on the furnace body, the tea leaves are repeatedly exposed to infrared radiation and heat radiation during the transportation process, thereby achieving drying and aroma enhancement; at the same time, the infrared heat radiation modules are independent of each other, forming a modular design, and the appropriate number can be selected and spliced ​​according to the roasting requirements, which achieves the effects of easy disassembly and transportation, reduced on-site installation and debugging time, and reduced workshop height and area requirements.

[0022] 2. In this utility model, each set of infrared heat radiation modules is equipped with two sets of cast iron pipes and a set of burners. When multiple sets of infrared heat radiation modules are spliced ​​together, the radiation source inside the furnace increases significantly, allowing the tea to receive radiation for a longer time and produce a higher aroma. At the same time, by using multiple low-power burners in combination, the problems of excessively concentrated combustion, excessively high combustion temperature, excessively small heat radiation area, and excessive heat energy waste of existing large burners are solved. By dispersing combustion, the combustion area is greatly increased, the heat radiation area increases simultaneously, the heat conversion efficiency is higher, and the energy-saving effect is obvious.

[0023] 3. In this utility model, by installing the lower cast iron pipe on a vertically movable mounting bracket, the lower cast iron pipe can move up and down, thereby adjusting the distance between it and the tea leaves, so that the tea leaves can receive infrared radiation more fully; at the same time, each set of mounting plates is independent, so that the lower cast iron pipe can be individually adjusted in vertical position according to different areas or different raw materials to achieve the optimal radiation distance.

[0024] 4. In this invention, by allowing the tea leaves to receive sufficient infrared and thermal radiation, the number of times the tea leaves are conveyed through the conveyor belt in the oven is reduced, thereby improving the roasting efficiency. Attached Figure Description

Detailed Implementation

[0033] 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 protection scope of the present utility model.

[0034] Example: A radiant tube tea grinder, such as Figures 1-7As shown, the furnace includes a furnace body 1 and a first conveyor belt 2, a second conveyor belt 3, and a third conveyor belt 4 installed inside the furnace body 1. The first conveyor belt 2, the second conveyor belt 3, and the third conveyor belt 4 are arranged from bottom to top. The left and right sides of the first conveyor belt 2 are exposed outside the furnace body 1. The right side of the first conveyor belt 2 is the feeding end for grinding tea. A first loose tea cover 6 is installed above the right side of the first conveyor belt 2. A loose tea machine 7 is installed below the left side of the first conveyor belt 2. The left side of the third conveyor belt 4 is exposed outside the furnace body 1. A second loose tea cover 8 is installed above the left side of the third conveyor belt 4. The loose tea machine 7 is connected to the second loose tea cover 8 by a pipe. The left side of the second conveyor belt 3 is exposed outside the furnace body 1. The left side of the second conveyor belt 3 is the discharging end for grinding tea.

[0035] During operation, the tea leaves fall from the first tea hood 6 to the right side of the first conveyor belt 2, and are then conveyed by the first conveyor belt 2 to the tea maker 7. The tea maker 7 then conveys the tea leaves to the second tea hood 8, from which the tea leaves fall to the left side of the third conveyor belt 4. The tea leaves are then conveyed sequentially on the third conveyor belt 4 and the second conveyor belt 3, and finally fall from the left side of the second conveyor belt 3 to the discharge conveyor (not shown). During the tea leaf conveying process, the furnace body 1 roasts the tea leaves through infrared radiation and heat convection.

[0036] The first conveyor belt 2, the second conveyor belt 3, and the third conveyor belt 4 are stainless steel mesh conveyor belts. Each set of conveyor belts is equipped with a corresponding active roller and a driven roller. The active roller is connected to the driven roller through the conveyor belt drive. The active roller is connected to a motor and drives the active roller to rotate through the motor. The conveyor belt, active roller, driven roller, and motor are all conventional products of the prior art. Their structure and connection method are not innovative in this embodiment, so they will not be described in detail here.

[0037] Preferably, a tea-loosening machine 7 can be installed on the right side of the first conveyor belt 2. The tea-loosening machine 7 is pipe-connected to the first tea-loosening cover 6. By cooperating with the first tea-loosening cover 6, the tea leaves can be automatically dropped onto the first conveyor belt 2. Both the tea-loosening machine 7 and the tea-loosening cover are conventional products of the prior art. Their structure, connection method and operating principle are not innovative in this embodiment, so they will not be described in detail here. The process of the tea-loosening machine 7 and the tea-loosening cover operating together is as follows: the tea-loosening machine 7 blows the tea leaves loaded in the hopper of the tea-loosening machine 7 to the upper part of the inner cavity of the tea-loosening cover through its internal blower. The tea leaves fall onto the conveyor belt under the action of gravity. By controlling the speed of the blower, the tea leaves are dispersed and fall onto the conveyor belt, so that the leaves do not overlap and pile up.

[0038] As a preferred option, such as Figure 2 and Figure 3As shown, a guide plate 9 is installed inside the furnace body 1 on the right side of the third conveyor belt 4. The guide plate 9 is located above the second conveyor belt 3. During the process of tea leaves being transferred from the third conveyor belt 4 to the second conveyor belt 3, the guide plate 9 is used to block the flow of tea leaves and its end is tilted inward to ensure that the tea leaves are effectively transferred onto the second conveyor belt 3 and to prevent the tea leaves from falling off the second conveyor belt 3.

[0039] Furthermore, such as Figures 1-3 As shown, multiple sets of infrared heat radiation modules 5 are arranged side by side along the length of the furnace body 1. That is, the multiple sets of infrared heat radiation modules 5 are arranged continuously without gaps. Each infrared heat radiation module 5 is independent. The appropriate number of infrared heat radiation modules 5 can be selected according to the baking time requirements. During installation, it is only necessary to splice them along the length of the furnace body 1. For example, in this embodiment, the number of infrared heat radiation modules 5 is 10 sets. The number of infrared heat radiation modules 5 can also be increased by splicing.

[0040] By modularizing the infrared thermal radiation modules 5, which can be assembled by splicing them together, the following advantages are achieved: First, it facilitates disassembly and transportation, significantly increasing the value of used equipment. Second, the equipment is manufactured in the factory, and testing and debugging can be completed before leaving the factory, improving product reliability. At the same time, it reduces on-site installation, lowers the technical requirements for installation personnel and installation and debugging time, reduces the trouble of early planning and communication in the processing workshop, and reduces the risk of customer construction errors. Third, it reduces the height and area requirements of the workshop, making it suitable for small factories.

[0041] Furthermore, such as Figure 3 As shown, each infrared thermal radiation module 5 includes an upper cast iron pipe 51 and a lower cast iron pipe 52 for the flow of high-temperature gas. The upper cast iron pipe 51 is horizontally located between the second conveyor belt 3 and the third conveyor belt 4, that is, between the lower mesh belt 22 of the second conveyor belt 3 and the upper mesh belt 21 of the third conveyor belt 4. The lower cast iron pipe 52 is horizontally located between the upper mesh belt 21 and the lower mesh belt 22 of the first conveyor belt 2. The flow direction of the high-temperature gas in the upper cast iron pipe 51 and the lower cast iron pipe 52 is perpendicular to the conveying direction of the tea grinding. The high-temperature gas can be the high-temperature exhaust gas after combustion of fuel gas.

[0042] During tea roasting, the high-temperature exhaust gas from the combustion of fuel gas is introduced into the upper cast iron pipe 51 and the lower cast iron pipe 52. As the high-temperature exhaust gas flows through the upper and lower cast iron pipes 51 and 52, it completes the heat storage process of the cast iron pipes. Heat is then conducted outward through the pipe walls of the upper and lower cast iron pipes 51 and 52, forming thermal radiation. At the same time, since the upper and lower cast iron pipes 51 and 52 are made of cast iron, they generate infrared radiation when heated. The tea leaves are repeatedly exposed to infrared radiation and thermal radiation during the conveying process, achieving drying and aroma enhancement. By ensuring that the flow direction of the high-temperature exhaust gas in the upper and lower cast iron pipes 51 and 52 is perpendicular to the conveying direction of the tea leaves, it is ensured that all tea leaves on the conveyor belt receive the same or similar infrared radiation, avoiding the situation where some tea leaves are over-roasted and others are under-roasted.

[0043] Preferably, each infrared thermal radiation module 5 is equipped with a temperature sensor, which is located on the upper mesh belt 21 of the first conveyor belt 2, the second conveyor belt 3 and the third conveyor belt 4 respectively, to monitor the temperature of each area of ​​the infrared thermal radiation module 5.

[0044] As a preferred option, such as Figure 1 and Figure 2 As shown, each infrared thermal radiation module 5 has an exhaust port 57 installed at its top, from which the water vapor evaporated from the tea leaves and the air inside the infrared thermal radiation module 5 are discharged.

[0045] As a preferred option, such as Figure 2 and Figure 3 As shown, the lower mesh belt 22 of the first conveyor belt 2 is exposed outside the furnace body 1 and located below the furnace body 1. This structural design achieves several advantages: first, it reduces the height of the furnace body 1; second, it reduces the space occupied by the first conveyor belt 2 within the furnace body 1, allowing for an increase in the diameter of the upper cast iron pipe 51 and the lower cast iron pipe 52. By increasing the thermal radiation area, the thermal radiation intensity is appropriately reduced, thereby decreasing the relative distance between the cast iron pipe and the tea leaves, allowing the tea leaves to receive infrared radiation more fully. Simultaneously, increasing the diameter of the cast iron pipe also increases the infrared radiation area; third, it facilitates the adjustment of the height of the lower cast iron pipe 52. Since the relationship between the infrared radiation intensity of cast iron and distance follows the inverse square law, doubling the distance reduces the infrared radiation intensity to one-quarter of its original value. Based on this law, by adjusting the height of the lower cast iron pipe 52, the distance between the lower cast iron pipe 52 and the tea leaves can be minimized, thereby reducing the temperature of the radiation source while achieving the same radiation intensity.

[0046] Furthermore, such as Figure 4As shown, both the upper cast iron pipe 51 and the lower cast iron pipe 52 have a serpentine structure. The upper cast iron pipe 51 and the lower cast iron pipe 52 are connected by a connecting pipe 53. By arranging the upper cast iron pipe 51 and the lower cast iron pipe 52 in a serpentine manner, the travel distance of the high-temperature exhaust gas is increased, fully utilizing the heat of the high-temperature exhaust gas, thereby improving the heat storage effect and increasing the area of ​​thermal radiation and infrared radiation.

[0047] By setting up a connecting pipe 53 to connect the upper cast iron pipe 51 and the lower cast iron pipe 52, on the one hand, the number of burners 54 required for a single infrared heat radiation module 5 is reduced, lowering costs and allowing full utilization of the heat from the high-temperature exhaust gas. On the other hand, the temperature difference formed when the high-temperature exhaust gas flows creates different temperatures in the areas where the upper cast iron pipe 51 and the lower cast iron pipe 52 are located, thus adapting to the different temperature requirements of tea at different roasting times. Preferably, the connecting pipe 53 is a telescopic pipe with a telescopic function to accommodate the height adjustment of the lower cast iron pipe 52. The upper and lower ends of the connecting pipe 53 are closed, and a sealing mechanism, such as a sealing ring, is provided at the telescopic position to ensure the sealing performance of the connecting pipe 53 during telescopic movement.

[0048] As a preferred option, such as Figure 2 and Figure 3 As shown, both ends of the upper cast iron pipe 51 are exposed to the second conveyor belt 3 and the third conveyor belt 4, that is, the distance between the two ends of the upper cast iron pipe 51 is greater than the width of the second conveyor belt 3 and the third conveyor belt 4. Both ends of the lower cast iron pipe 52 are exposed to the first conveyor belt 2, that is, the distance between the two ends of the lower cast iron pipe 52 is greater than the width of the first conveyor belt 2. With the above structural design, the tea leaves located on both sides of the conveyor belt can also receive sufficient infrared radiation.

[0049] Furthermore, such as Figures 3-5 As shown, each infrared thermal radiation module 5 is equipped with a small burner 54. The burner 54 includes a housing 541 with a blower 542 installed. The air outlet of the blower 542 is connected to the lower cast iron pipe 52. A gas interface 543 is installed on the outer wall of the housing 541. The gas interface 543 is used to connect to a gas source. An air inlet pipe 544 is installed on the gas interface 543. The end of the air inlet pipe 544 passes through the housing 541 and extends into the inner cavity of the housing 541. A nozzle 545 is installed at the end of the air inlet pipe 544. An ignition needle 546 is installed in the inner cavity of the housing 541. The ignition needle 546 is located at the nozzle 545. A controller 547 is installed on the outer wall of the housing 541. The controller 547 is electrically connected to the blower 542 and the ignition needle 546.

[0050] In use, the gas interface 543 is connected to the gas source, such as the gas interface 543 being connected to the gas cylinder through a hose. The gas cylinder contains gas, which flows through the gas interface 543 and the inlet pipe 544 to the nozzle 545. The nozzle 545 sprays out the gas, which is ignited by an electric spark generated by an ignition needle. The blower 542 is used to transfer outside air into the lower cast iron pipe 52, and under the action of the blower 542, the high-temperature exhaust gas after the gas combustion flows along the lower cast iron pipe 52, the connecting pipe 53, and the upper cast iron pipe 51.

[0051] Since each set of infrared heat radiation modules 5 is equipped with two sets of cast iron pipes and one set of burners 54, when multiple sets of infrared heat radiation modules 5 are spliced ​​together, the radiation source in the furnace body 1 is greatly increased, allowing the tea to receive radiation for a longer time and produce a higher aroma. At the same time, by using multiple low-power burners 54 in combination, the problems of excessively concentrated combustion, excessively high combustion temperature, excessively small heat radiation area, and excessive heat energy waste of existing large burners 54 are solved. By dispersing combustion, the combustion area is greatly increased, the heat radiation area is increased simultaneously, the heat conversion efficiency is higher, and the energy-saving effect is obvious.

[0052] As a preferred option, such as Figure 4 and Figure 5 As shown, an air inlet hood 549 is installed on the housing 541 at the air inlet position of the blower 542. The air intake volume of the blower 542 can be adjusted by changing the size of the opening at the air inlet end of the air inlet hood 549.

[0053] As a preferred option, such as Figures 2-4 As shown, an exhaust pipe 58 is installed at the end of the upper cast iron pipe 51. The end of the exhaust pipe 58 penetrates the furnace body 1 and extends to the outside of the furnace body 1.

[0054] As a preferred option, such as Figure 4 As shown, a pressure reducing valve 548 is installed on the outer wall of the housing 541. The pressure reducing valve 548 is connected to the gas interface 543 through a hose. The pressure reducing valve 548 is used to control the gas pressure and flow rate. In use, the pressure reducing valve 548 is connected to the gas source through a hose.

[0055] Furthermore, such as Figure 3As shown, the upper cast iron pipe 51 is fixedly installed on the frame 11 of the furnace body 1, and the lower cast iron pipe 52 is fixedly installed on the mounting bracket 55. The mounting bracket 55 is installed inside the furnace body 1 and can move up and down. By installing the lower cast iron pipe 52 on the vertically movable mounting bracket 55, the lower cast iron pipe 52 can move up and down, thereby adjusting the distance between the lower cast iron pipe 52 and the tea leaves on the first conveyor belt 2. At the same time, since each set of infrared heat radiation modules 5 is equipped with a set of vertically movable mounting plates, and each set of mounting plates is independent of each other, the lower cast iron pipe 52 in each set of infrared heat radiation modules 5 can move up and down independently to adjust its distance from the tea leaves. Therefore, the vertical position of the lower cast iron pipe 52 can be adjusted individually according to different areas or different raw materials to achieve the optimal radiation distance.

[0056] Furthermore, such as Figure 6 As shown, a height adjustment mechanism 56 is installed on the mounting bracket 55, which is used to adjust the vertical height of the mounting bracket 55. The height adjustment mechanism 56 can take various forms and is not limited to screw drive, motor drive, or cylinder drive. Any mechanism that can enable the mounting bracket 55 to move vertically is acceptable. For example, the output end of a cylinder can be connected to the mounting bracket 55, and the vertical height of the mounting bracket 55 can be adjusted by using the cylinder drive.

[0057] Furthermore, such as Figure 6 and Figure 7 As shown, the mounting frame 55 has a rectangular structure. Each of the four corners of the mounting frame 55 is equipped with a height adjustment mechanism 56. Each height adjustment mechanism 56 includes a vertically mounted screw 561 threadedly connected to the furnace body 1 frame 11. One end of the screw 561 is located inside the furnace body 1 and rotatably connected to the mounting frame 55, while the other end is located outside the furnace body 1 and fixedly fitted with a first nut 562. During adjustment, the first nut 562 is turned to drive the screw 561 to rotate. The rotation of the screw 561 causes it to move up and down, which in turn drives the mounting plate to move up and down. Because there are four height adjustment mechanisms 56, a height measuring instrument must be used in conjunction with the mounting plate during height adjustment to ensure the mounting plate is level.

[0058] Preferably, the screw 561 is threadedly connected to a second nut 563, which is located inside the furnace body 1 and abuts against the frame 11 of the furnace body 1. The second nut 563 is provided to limit the adjustment position of the screw 561.

[0059] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
