[0020] 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.
[0021] Example 1
[0022] Please see Figure 1-4 The present invention provides the following technical solution: a temperature control device for a black tea withering trough, comprising a temperature control box 6, the temperature control box 6 being fixedly installed on one side of the withering trough assembly 1, a heat insulation layer 7 being fixedly installed near the center of the withering trough assembly 1, a screen 4 being fixedly installed on the inner side of the heat insulation layer 7, an electric heating tube 3 being fixedly installed on the inner side of the heat insulation layer 7 and below the screen 4, a cooling and anti-separation device 2 being provided on the outer side of the withering trough assembly 1, and an isolation protection device 5 being fixedly installed on one side of the withering trough assembly 1 and above the temperature control box 6.
[0023] Specifically, the cooling and anti-separation device 2 includes a fixed cylinder 21, a fan 22, a cooling rod 23, and an anti-separation component 25. The fixed cylinder 21 is fixedly installed on the side of the withering tank assembly 1 away from the temperature control box 6 near the edge. The fan 22 is fixedly installed on the side of the fixed cylinder 21 away from the withering tank assembly 1. Multiple cooling rods 23 are fixedly installed near the center of the fixed cylinder 21. The anti-separation component 25 is installed above the fixed cylinder 21.
[0024] By adopting the above technical solution, staff can reduce the temperature inside the withering tank assembly 1 when needed by cooperating with structures such as the fan 22 and the cooling rod 23, thereby better meeting the needs of temperature control.
[0025] Specifically, the cooling and anti-separation device 2 also includes a fan 24, and multiple fans 24 are fixedly installed below the fixed cylinder 21 and on one side of the bottom of multiple cooling rods 23.
[0026] By adopting the above technical solution, staff can blow air onto the heat dissipated by each cooling rod 23 when needed, thereby accelerating the diffusion of heat dissipated by each cooling rod 23 and ensuring the normal operation of the refrigeration work.
[0027] Specifically, the anti-separation component 25 includes an electric lifting rod 251, a lifting plate 252, a connecting plate 253, screws 254, and a mesh cover 255. The lifting plate 252 is provided above the fixed cylinder 21, and the fixed cylinder 21 and the lifting plate 252 are connected by the electric lifting rod 251. The connecting plate 253 is provided above the lifting plate 252, and the lifting plate 252 and the connecting plate 253 are connected by two screws 254. A mesh cover 255 is fixedly installed on one side of the connecting plate 253 and above the withering trough component 1.
[0028] By adopting the above technical solution, the staff can close the top of the withering tank assembly 1 when needed by using the mesh cover 255 and the electric lifting rod 251, thereby preventing the tea leaves from being blown away by the airflow during temperature control.
[0029] In this embodiment, when the temperature inside the withering trough assembly 1 needs to be controlled during black tea processing, the operator controls the temperature control box 6. Through the cooperation of the electric heating tube 3 and the withering trough assembly 1, the inside of the withering trough assembly 1 is heated, thereby increasing the temperature inside the withering trough assembly 1 and subsequently withering the black tea leaves on the sieve 4. When withering is complete or other conditions arise, the operator can activate the fan 22, each cooling rod 23, and each fan 24 in the cooling and anti-separation device 2. The fan 22 sends air into the fixed cylinder 21, the cooling rods 23 lower the air temperature, and the fans 24 provide cooling. Air is blown from the bottom of rod 23 to accelerate the diffusion of heat. Then, cold air enters the withering trough assembly 1, thereby reducing the temperature inside the withering trough assembly 1 and cooling the black tea leaves on the screen 4. This facilitates operation by the staff. When needed, the staff can activate the electric lifting rod 251 in the anti-separation assembly 25, which will drive the screen cover 255 to descend through the lifting plate 252, screw 254 and connecting plate 253, thereby sealing the top of the withering trough assembly 1 and preventing the tea leaves from being blown away by the airflow during temperature control. The heat insulation layer 7 plays a role in heat insulation.
[0030] Example 2
[0031] The difference between this embodiment and embodiment 1 is that the isolation protection device 5 includes a support plate 51, an electric telescopic rod 52 and an isolation shell 53. The support plate 51 is fixedly installed on one side of the withering trough assembly 1 and above the temperature control box 6. An isolation shell 53 is provided between the support plate 51 and the temperature control box 6. The support plate 51 and the isolation shell 53 are connected by the electric telescopic rod 52.
[0032] By adopting the above technical solution, staff can use the electric telescopic rod 52 and the isolation shell 53 to provide a certain degree of isolation and protection for the temperature control box 6 when needed, thereby reducing the possibility of the temperature control box 6 being accidentally touched or damaged.
[0033] Specifically, the isolation protection device 5 also includes an elastic rubber layer 54, which is fixedly installed on the outside of the isolation shell 53.
[0034] By adopting the above technical solution, the device can buffer external collisions through the elastic rubber layer 54, thereby improving the protection capability of the isolation protection device 5 and better meeting the needs of the work.
[0035] In this embodiment, when the staff does not need to touch the temperature control box 6 temporarily, the electric telescopic rod 52 on the support plate 51 of the isolation protection device 5 can be activated, thereby driving the isolation shell 53 to descend and cover the temperature control box 6. Then, the temperature control box 6 can be protected by the isolation shell 53 and the elastic rubber layer 54, thereby reducing the possibility of the temperature control box 6 being accidentally touched or damaged, and ensuring the normal operation of temperature control.
[0036] The structure and principle of the withering trough assembly 1 (comprising withering trough, fan, and wall), electric heating tube 3, screen 4, temperature control box 6, and insulation layer 7 in this utility model have been disclosed in the black tea withering trough temperature control device disclosed in Chinese patent application number 201220277263.3. Its working principle is to turn on the control switch of the electric heating tube to heat it, and then blow air to make the tea leaves on the screen lose water to achieve the purpose of withering. It can accurately control the withering temperature of black tea leaves, laying the foundation for improving the quality of black tea processing. It can save 20% of energy consumption costs per round, reduce labor by half, and realize intelligent automatic control.
[0037] The structure and principle of the cooling rod 23 in this utility model have been disclosed in a high-temperature cooling device for a kiln used in the production of light calcium carbonate, disclosed in Chinese patent application number 202022664354.X. Its working principle consists of a cooling end, a cooling section, a heat-conducting section, and a heat-dissipating section. The heat around the cooling end can be transferred to the cooling section through the cooling end. The heat-conducting section is connected to the heat-dissipating section, and the heat-dissipating section can dissipate the heat from the heat-conducting section. After the heat on the cooling section is transferred to the heat-conducting section, the heat is discharged through the heat-dissipating section, thereby dissipating the heat around the cooling end and making the area around the cooling end cool.
[0038] The working principle and usage process of this utility model are as follows: When the temperature inside the withering trough assembly 1 needs to be controlled during black tea processing, the operator controls the temperature control box 6. Through the cooperation of the electric heating tube 3 and the withering trough assembly 1, the inside of the withering trough assembly 1 is heated, thereby increasing the temperature inside the withering trough assembly 1 and thus withering the black tea leaves on the screen 4. When withering is complete or other conditions arise, the operator can activate the fan 22, each cooling rod 23, and each fan 24 in the cooling and anti-separation device 2. The fan 22 sends air into the fixed cylinder 21, the cooling rods 23 lower the air temperature, and the fans 24 blow air onto the bottom of the cooling rods 23, accelerating the diffusion of the heat carried out on them. Then, the cold air enters the withering trough assembly 1, thereby lowering the temperature inside the withering trough assembly 1 and thus withering the black tea leaves on the screen 4. The black tea leaves are cooled to facilitate operation by staff. When needed, staff can activate the electric lifting rod 251 in the anti-separation component 25, which lowers the mesh cover 255 via the lifting plate 252, screw 254, and connecting plate 253, thereby sealing the top of the withering trough component 1. This prevents the tea leaves from being blown away by airflow during temperature control. The heat insulation layer 7 also provides heat insulation. When staff do not need to touch the temperature control box 6 temporarily, they can activate the electric telescopic rod 52 on the support plate 51 in the isolation protection device 5, which lowers the isolation shell 53 to cover the temperature control box 6. The isolation shell 53 and the elastic rubber layer 54 then protect the temperature control box 6, reducing the possibility of accidental contact or damage and ensuring the normal operation of temperature control.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
