Description

Technical Field

[0001] This utility model relates to the field of pectin production equipment technology, and more specifically to a pectin processing alcohol recovery device. Background Technology

[0002] After alcohol precipitation, pectin is separated by pressing using a filter press. The alcohol used for precipitation is a high-concentration 98° alcohol. Alcohol recovery is a crucial step in the filtration process. This involves recovering alcohol from the filter press itself, and also recovering alcohol from the high concentration of alcohol in the air within the pectin separation chamber, as alcohol is volatile and requires proper handling. Failure to do so would result in significant waste, increased production costs, and the irritating effects of alcohol on operators' health, posing safety hazards. Existing alcohol recovery devices are relatively limited in function, mostly only recovering alcohol from the filter press and not from the alcohol volatilized in the air, thus failing to meet the requirements of enterprises. Therefore, the inventors propose an alcohol recovery device for pectin processing to address this problem. This device can recover alcohol leaking from the filter press and alcohol volatilized in the air, improving the alcohol recovery rate while ensuring production safety, reducing production costs, and protecting employee health.

[0003] To effectively recover the alcohol generated during pectin filtration, ensuring safe production and improving efficiency, Chinese patent application (publication number CN221491574U) discloses an alcohol recovery device for a pectin separation chamber. This invention includes a protective cover over a plate and frame filter press. The bottom of the protective cover is open, and a suction mechanism is connected to the top. A conveying channel is located below the protective cover, and side baffles are installed inside the conveying channel. The top of the side baffles is hinged to the bottom of the protective cover, and the two side baffles are symmetrically arranged about the central axis of the plate and frame filter press. A conveying mechanism is located below the side baffles. This invention has the advantages of facilitating continuous production operation of the plate and frame filter press and improving pectin production efficiency.

[0004] The proposed solution still has some shortcomings in its application. Since alcohol evaporates from various components of the filter press during filtration, effective collection around the filter press is necessary; otherwise, the collection rate will be low, affecting the safety of the pectin separation chamber. Simultaneously, the filter press also produces liquid alcohol during the filtration process, which also needs to be recovered to avoid significant waste and production safety issues. Therefore, the structure of the alcohol recovery device needs improvement to enable the recovery of both liquid and gaseous alcohol with good recovery efficiency, thereby improving pectin production efficiency and ensuring production safety. Utility Model Content

[0005] This utility model discloses an alcohol recovery device for pectin processing, the main purpose of which is to overcome the above-mentioned deficiencies and shortcomings of the existing technology.

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

[0007] An alcohol recovery device for pectin processing includes a recovery hood and a recovery pool. The recovery pool is disposed inside the recovery hood. A filter press body is built into the middle of the recovery hood. The top of the recovery hood has a semi-circular structure, which includes an outer layer and an inner layer. A cavity is formed between the outer layer and the inner layer. A suction fan is installed on the top of the cavity. A plate condenser is installed on one side of the recovery hood. A connecting pipe is provided between the inlet end of the plate condenser and the suction fan. A water outlet tank is provided on one side of the filter press body. A filter chamber is installed at the end of the water outlet tank. The bottom of the filter chamber is connected to the recovery pool.

[0008] Furthermore, the outer layer adopts a sealed structure and has a first opening in the middle, which is connected to the air inlet of the suction fan, and the inner layer is provided with several through-holes.

[0009] Furthermore, the outlet end of the plate condenser is connected to the recovery tank via a pipeline.

[0010] Furthermore, a second opening is provided on one side of the filter chamber, and a first filter screen is detachably installed in the second opening. A second filter screen is detachably installed in the lower part of the filter chamber.

[0011] Furthermore, the recycling tank is equipped with a liquid level sensor and has an outlet on one side, which is equipped with an on / off valve.

[0012] Furthermore, an alcohol concentration detector is installed on one side of the filter press body.

[0013] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0014] This invention first incorporates a filter press within a recovery hood, with several through-holes in the inner layer of the hood. An external suction fan draws volatile alcohol through these through-holes into the cavity, ultimately leading to a plate condenser where it flows into a recovery tank. This method effectively removes all gaseous alcohol from the recovery hood, preventing alcohol buildup in surrounding areas and ensuring high recovery efficiency. Next, a filter chamber is located at the end of the outlet tank on one side of the filter press. Residual liquid alcohol filtered from the filter press is filtered through a first and second filter screen in the chamber before flowing into the recovery tank. This design effectively recovers liquid alcohol remaining on the pectin, further improving the alcohol recovery rate. Finally, an alcohol concentration detector is installed on one side of the filter press to monitor the alcohol concentration within the recovery hood in real time. When the alcohol concentration is too high, the suction speed of the suction fan can be increased, allowing for flexible adjustment. This ingenious design enables alcohol recovery during pectin filtration, achieving a high recovery rate and strong practicality, making it suitable for widespread adoption.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0019] like Figures 1 to 3 As shown, a pectin processing alcohol recovery device includes a recovery hood 1 and a recovery pool 2. The recovery pool 2 is disposed inside the recovery hood 1. A filter press body 3 is built into the middle of the recovery hood 1. The top of the recovery hood 1 has a semi-circular structure 11, which includes an outer layer 12 and an inner layer 13. A cavity 14 is formed between the outer layer 12 and the inner layer 13. A suction fan 4 is installed on the top of the cavity 14. A plate condenser 5 is installed on one side of the recovery hood 1. A connecting pipe is provided between the inlet end of the plate condenser 5 and the suction fan 4. A water outlet trough 6 is provided on one side of the filter press body 3. A filter chamber 7 is installed at the end of the water outlet trough 6. The bottom of the filter chamber 7 is connected to the recovery pool 2.

[0020] Furthermore, the outer layer 12 adopts a sealed structure and has a first opening in the middle, which is connected to the air inlet of the suction fan 4, and the inner layer 13 is provided with a number of through holes 15.

[0021] Furthermore, the outlet end of the plate condenser 5 is connected to the recovery tank 2 via a pipe.

[0022] Furthermore, a second opening is provided on one side of the filter chamber 7, and a first filter screen 71 is detachably installed in the second opening. A second filter screen 72 is detachably installed at the lower part of the filter chamber 7.

[0023] Furthermore, the recycling tank 2 is equipped with a liquid level sensor 8 and has an outlet on one side, which is equipped with an on / off valve 9.

[0024] Furthermore, an alcohol concentration detector 10 is installed on one side of the filter press body 3.

[0025] [Example]

[0026] First, after alcohol precipitation, the pectin is pressed using a filter press body 3. Since the pectin has just undergone alcohol precipitation, it still contains a high concentration of alcohol. During the filtration process, some of the alcohol will evaporate and disperse into the air. This part of the alcohol is in gaseous form and is adsorbed upward by the suction fan 4. Since the inner layer 13 is provided with several through-holes 15, the gaseous alcohol is adsorbed upward by the suction fan 4 through the through-holes 15 into the plate condenser 5. It is condensed by the plate condenser 5 into liquid and drips into the recovery tank 2. Then, some of the unevaporated alcohol in the pectin is filtered by the filter press body 3 and drips into the outlet tank 6. After being filtered by the first filter screen 71 and the second filter screen 72 in the filter chamber 7, it also flows into the recovery tank 2. Finally, when the alcohol in the recovery tank 2 reaches a certain amount, it is sensed by the liquid level sensor 8, and the worker opens and closes the valve 9 to recover the alcohol. At the same time, the alcohol concentration detector 10 on one side of the filter press body 3 monitors the alcohol concentration in the recovery hood 1 in real time to prevent the alcohol concentration in the recovery hood 1 from being too high.

[0027] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0028] This invention first incorporates a filter press within a recovery hood, with several through-holes in the inner layer of the hood. An external suction fan draws volatile alcohol through these through-holes into the cavity, ultimately leading to a plate condenser where it flows into a recovery tank. This method effectively removes all gaseous alcohol from the recovery hood, preventing alcohol buildup in surrounding areas and ensuring high recovery efficiency. Next, a filter chamber is located at the end of the outlet tank on one side of the filter press. Residual liquid alcohol filtered from the filter press is filtered through a first and second filter screen in the chamber before flowing into the recovery tank. This design effectively recovers liquid alcohol remaining on the pectin, further improving the alcohol recovery rate. Finally, an alcohol concentration detector is installed on one side of the filter press to monitor the alcohol concentration within the recovery hood in real time. When the alcohol concentration is too high, the suction speed of the suction fan can be increased, allowing for flexible adjustment. This ingenious design enables alcohol recovery during pectin filtration, achieving a high recovery rate and strong practicality, making it suitable for widespread adoption.
