Description

Technical Field

[0001] This utility model belongs to the field of tea processing technology, specifically relating to a vacuum freeze-drying device for preventing breakage of aged white tea. Background Technology

[0002] Aged white tea with a distinctive aroma is a type of white tea produced using a special processing technique. Its unique aroma and taste make it highly sought after by tea enthusiasts. Vacuum freeze-drying technology can preserve the color, aroma, flavor, and nutrients of tea leaves to the greatest extent, making it an ideal method for processing high-end aged white tea. Therefore, vacuum freeze-drying equipment is used when processing and drying aged white tea with a distinctive aroma.

[0003] The principle of freeze-drying is to remove moisture by sublimating water from a solid state to a gaseous state at low temperatures. To achieve this, a vacuum below atmospheric pressure needs to be maintained inside the drying chamber. Traditional freeze-drying devices often require an external vacuum pump connected to the freeze-drying unit's vacuum chamber via piping.

[0004] However, when connecting the pipes to the freeze-drying unit, workers need to use connecting flanges or screws to ensure the pipes are secure. The installation process of connecting flanges or screws is relatively complicated, requiring precise alignment and tightening, which not only prolongs downtime but also affects the efficiency of tea drying and processing. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum freeze-drying device for aged white tea that prevents breakage. It can quickly connect the vacuum pump to the drying device through a connecting mechanism, simplifying the installation process, reducing downtime, and improving work efficiency.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A vacuum freeze-drying device for preventing breakage of aged white tea includes a main body of the drying device. A connector is connected to one side of the main body, and a vacuum pump is installed on the same side. A pipe is connected to the top of the vacuum pump, and a connecting pipe is connected to the other end of the pipe. The connecting pipe is fitted onto the surface of the connector, and a quick-connect mechanism is provided on the surface of the connecting pipe. The quick-connect mechanism includes a positioning groove, a ring, a telescopic spring, a slot, a positioning ball, and a collar. The positioning groove is formed on the outer surface of the connector. The ring is fixedly connected to the surface of the connecting pipe. The telescopic spring is movably fitted onto the surface of the connecting pipe, with one end fixedly connected to one side of the ring. The slot is formed on the surface of the connecting pipe and extends through it. The positioning ball is located inside the slot and is adapted to the positioning groove. The collar is movably fitted onto the surface of the connecting pipe, and its inner wall is fixedly connected to the other end of the telescopic spring.

[0008] Preferably, the connector and the connecting pipe head are provided with a sealing mechanism inside. The sealing mechanism includes a sealing retaining ring, a compression spring, a sealing element, a vent hole, a mating part, a round hole, and a sealing plug. The sealing retaining ring is fixedly connected to the inner wall of the connector and the connecting pipe head respectively. One end of the compression spring is fixedly connected to the inner side of the sealing retaining ring respectively. The sealing element is fixedly connected to the outer end of the connector and the connecting pipe head respectively. The vent hole is opened at the round part of the sealing element respectively. The mating part is fixedly connected to the other end of the compression spring and is slidably connected to the inside of the connector and the connecting pipe head respectively. The round hole is opened on the surface of the mating part respectively. The sealing plug is fixedly connected to the inner side of the mating part respectively. The sealing plug is in close contact with the sealing element and is adapted to the vent hole.

[0009] Preferably, the sealing plug is conical in shape, and the outer side of the sealing element has a conical groove that mates with the conical sealing plug.

[0010] Preferably, there are several circular holes, which are evenly distributed on one side of the mating part.

[0011] Preferably, protrusions are fixedly connected to the top and bottom of the annular surface, and grooves that cooperate with the protrusions are provided on the top and bottom of the inner wall of the collar.

[0012] Preferably, there are several positioning balls, which are equidistantly distributed inside the positioning groove.

[0013] Preferably, an anti-slip strip is fixedly connected to the surface of the collar, and the anti-slip strip is made of rubber.

[0014] The technical effects achieved by this utility model are as follows:

[0015] In this invention, when connecting the main body of the drying device to the vacuum pump, one end of the pipe can be connected to the top of the vacuum pump, and the connecting pipe head at the other end of the pipe can be connected to the connector on one side of the main body of the drying device. During connection, the collar is first pulled outward. The outward movement of the collar will compress the telescopic spring, and the collar will no longer obstruct the positioning ball. Then, the connecting pipe head is put on the surface of the connector. At the same time as the collar is put on, the connector will push the positioning ball outward. After the connecting pipe head and the connector are put on, the positioning ball can be locked in the positioning groove on the surface of the connector. Finally, the hand is removed from the collar, and the elastic force of the telescopic spring will push the collar to move inward. The inward movement of the collar will block the positioning ball and make the positioning ball firmly locked in the inside of the positioning groove. This allows the connecting pipe head to be quickly connected and installed to the connector on one side of the main body of the drying device, improving the installation efficiency of the vacuum pump and the main body of the drying device, reducing equipment downtime, and further improving the processing efficiency of tea. Moreover, the double-layer connection and sealing of the connecting pipe head and the collar reduces the air leakage problems that may be caused by traditional screw and flange connections.

[0016] In this invention, when the connecting pipe head and the connector are connected, the two internal sealing plugs will press against each other and press against the mating parts. The mating parts will then press against the compression springs, and the mating parts and sealing plugs will act as seals. During operation, the vacuum can be pumped through the round vent hole. With the cooperation of the sealing rings, seals, mating parts, and sealing plugs inside the connector and connecting pipe head, the inside of the connector and connecting pipe head can be sealed layer by layer, thereby improving the sealing effect during equipment operation, ensuring the stability of the vacuum system, preventing vacuum gas leakage, and improving the stability of the environment during the tea drying process.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-4As shown, a vacuum freeze-drying device for preventing breakage of aged white tea includes a drying device body 1. A connector 101 is connected to one side of the drying device body 1. A vacuum pump 102 is installed on one side of the drying device body 1. A pipe 103 is connected to the top of the vacuum pump 102. A connecting pipe head 104 is connected to the other end of the pipe 103. The connecting pipe head 104 is fitted onto the surface of the connector 101. A quick-connect mechanism is provided on the surface of the connecting pipe head 104. The quick-connect mechanism includes a positioning groove 201, a ring 202, and a telescopic spring 20. 3. Groove 204, positioning ball 205, and collar 206: The positioning groove 201 is formed on the outer surface of the connector 101; the ring 202 is fixedly connected to the surface of the connecting pipe head 104; the telescopic spring 203 is movably sleeved on the surface of the connecting pipe head 104, with one end of the telescopic spring 203 fixedly connected to one side of the ring 202; the groove 204 is formed on the surface of the connecting pipe head 104 and penetrates the connecting pipe head 104; the positioning ball 205 is disposed inside the groove 204, and the positioning ball 205 is adapted to the positioning groove 201. The collar 206 is movably fitted onto the surface of the connecting pipe head 104, and the inner wall of the collar 206 is fixedly connected to the other end of the telescopic spring 203. With the cooperation of the quick-connect mechanism, the connecting pipe head 104 and the connector 101 can be quickly and accurately connected. The cooperation of the positioning groove 201 and the positioning ball 205 makes the connection more stable, reduces the possibility of human intervention, and improves operational efficiency. The quick-connect mechanism effectively reduces installation and disassembly time, effectively improving efficiency during tea processing. After connecting the connecting tube head 104 and the connector 101, the collar 206 can be positioned on the surface of the connecting tube head 104 under the push of the telescopic spring 203. At the same time, the collar 206 will wrap and squeeze the positioning ball 205 inside the groove 204, and make the positioning ball 205 stably locked inside the positioning groove 201. With the cooperation of the positioning ball 205 and the groove 204 and the wrapping of the collar 206, the sealing of the connecting tube head 104 and the connector 101 is ensured, and the drying effect of the tea is avoided due to air leakage.

[0025] like Figures 2-4As shown, the connector 101 and the connecting pipe head 104 are equipped with a sealing mechanism. The sealing mechanism includes a sealing ring 301, a compression spring 302, a sealing element 303, a vent 304, a mating part 305, a round hole 306, and a sealing plug 307. The sealing ring 301 is fixedly connected to the inner wall of the connector 101 and the connecting pipe head 104. One end of the compression spring 302 is fixedly connected to the inner side of the sealing ring 301. The sealing element 303 is fixedly connected to the outer end of the connector 101 and the connecting pipe head 104. The vent 304 is opened at the circular part of the sealing element 303. The mating part 305 is fixedly connected to the other end of the compression spring 302 and is slidably connected to the inside of the connector 101 and the connecting pipe head 104. The round hole 306 is opened on the surface of the mating part 305. The sealing plug 307 is fixedly connected to the inner part of the mating part 305. On the side, the sealing plug 307 is in close contact with the sealing element 303 and is adapted to the vent 304. Through the cooperation of the sealing mechanism, the setting of the vent 304 can accurately control the gas discharge and prevent equipment failure caused by sudden gas outflow or uneven pressure. The cooperation between the sealing plug 307 and the vent 304 ensures that the sealing plug 307 will squeeze each other when the connecting pipe head 104 and the connector 101 are connected, and the gas will be discharged from the vent 304. This will also extract the moisture inside the drying device body 1 to achieve a vacuum state, ensuring the stability of the drying process. Furthermore, through the action of the sealing ring 301, the sealing element 303 and the mating part 305, the connection and the inside of the connecting pipe head 104 can be sealed layer by layer, thereby improving the sealing effect during equipment operation, ensuring the stability of the vacuum system, preventing vacuum gas leakage, and improving the stability of the environment during the tea drying process.

[0026] like Figure 4 As shown, the sealing plug 307 is conical in shape, and the outer side of the sealing element 303 has a conical groove that mates with the conical sealing plug 307. The conical design helps the sealing plug 307 to automatically align with the sealing element 303 during engagement, and as the sealing plug 307 is inserted, the pressure distribution of the sealing element 303 becomes more uniform. Therefore, the conical structure can guide the sealing plug 307 to move towards the center, avoiding local leakage or sealing failure due to loose engagement, so that the entire sealing mechanism can maintain a stable sealing effect under different pressures.

[0027] like Figures 2-4 As shown, there are several circular holes 306, which are evenly distributed on one side of the mating part 305. The multiple evenly distributed circular holes 306 enable the vacuum pump 102 to pass through the multiple circular holes 306 evenly during operation. The uniform air passage design reduces airflow resistance, enabling the vacuum pump 102 to extract gas more smoothly, improve pumping efficiency, and maintain a relatively stable pressure and flow rate during operation.

[0028] like Figure 4 As shown, protrusions 401 are fixedly connected to the top and bottom of the surface of the ring 202. The top and bottom of the inner wall of the collar 206 are provided with sliding grooves 402 that cooperate with the protrusions 401. When the collar 206 is pulled to move, the collar 206 can be limited and guided to move smoothly under the cooperation of the sliding grooves 402 and the protrusions 401, so as to avoid the instability or displacement caused by the free movement of the collar 206, which would affect the connection and sealing effect between the connecting pipe head 104 and the connector 101.

[0029] like Figure 4 As shown, there are several positioning balls 205, which are equidistantly distributed inside the positioning groove 201. The equidistantly distributed positioning balls 205 can evenly distribute the load in the positioning groove 201, avoiding local overload. By dispersing the pressure, it can effectively prevent excessive wear at a single position, reduce the failure or damage caused by excessive load on the quick-connect mechanism, and thus improve the reliability and service life of the quick-connect mechanism.

[0030] like Figures 2-4 As shown, an anti-slip strip 5 is fixedly connected to the surface of the collar 206. The anti-slip strip 5 is made of rubber. When the collar 206 is pulled, the operator's palm can increase the friction between the collar 206 and the collar 206, avoiding slippage or slipping during the pulling process, thereby providing higher operational stability.

[0031] The working principle of this utility model is as follows: When it is necessary to connect the main body 1 of the drying device to the vacuum pump 102, one end of the pipe 103 can be connected to the top of the vacuum pump 102, and the connecting pipe head 104 at the other end of the pipe 103 can be connected to the connector 101 on one side of the main body 1 of the drying device. When connecting, first pull the collar 206 outward. The outward movement of the collar 206 will compress the telescopic spring 203, and the collar 206 will no longer block the positioning ball 205. Then, the connecting pipe head 104 is put on the surface of the connector 101. At the same time as the connection is made, the connector 101 will push the positioning ball 205 outward. After the connecting pipe head 104 and the connector 101 are connected, the positioning ball 205 can be locked in place on the connector. Within the positioning groove 201 on the surface of 101, finally, remove your hand from the collar 206. Under the elastic force of the telescopic spring 203, the collar 206 can be pushed to move inward. The inward movement of the collar 206 can block the positioning ball 205 and make the positioning ball 205 firmly locked inside the positioning groove 201. This allows the connecting pipe head 104 to be quickly connected and installed to the connector 101 on one side of the drying device body 1. This improves the installation efficiency of the vacuum pump 102 and the drying device body 1, reduces equipment downtime, and further improves the processing efficiency of tea. Moreover, the double-layer connection and seal between the connecting pipe head 104 and the collar 206 reduces the air leakage problems that may be caused by traditional screw and flange connections.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
