It then continues to rotate forward, raising the filter plate to the top of the tank. The adjusting cylinder is then opened to lift the cover, allowing manual scraping of fruit pulp particles from the filter plate using tools, facilitating easy removal of residue. This solves the problem of microbial growth caused by residue retention in traditional devices, achieving convenient residue removal. Attached Figure Description

[0028] 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.

[0029] Example 1

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, one embodiment of the present invention is provided: a denitrification and buoyancy reduction device for canned fruit pulp beverages, including a tank body 1, a cover 4 movably provided on the top of the tank body 1, and a buoyancy reduction component 3 provided inside the tank body 1. A side plate 11 is welded to the bottom of one side of the tank body 1, and an air extraction device 2 is fixedly installed on the side plate 11. The air extraction device 2 is connected to the inside of the tank body 1.

[0031] The cover 4 is movably connected to the tank 1 through the adjusting cylinder 12. A sealing ring 41 is fixedly installed at the bottom of the cover 4, and the size of the sealing ring 41 is adapted to the inner diameter of the tank 1.

[0032] The buoyancy control assembly 3 includes a lead screw 33, which is vertically and rotatably installed inside the tank 1. A filter plate 34 is installed on the lead screw 33 by a threaded connection. A rectangular hole is opened at the top of the lead screw 33, and a matching transmission rod 32 is movably inserted into the hole. The top of the transmission rod 32 passes through the top of the cover 4, and the transmission rod 32 is rotatably connected to the cover 4 by a bearing 421.

[0033] Specifically, by setting up an air extraction device 2, which is connected to the inside of the tank 1, after the air extraction device 2 is started, the air inside the tank is extracted through the exhaust pipe 431 and the spiral hose 21. Within 3-5 minutes, a negative pressure environment of 0.05-0.08MPa can be formed inside the tank, which can efficiently remove dissolved nitrogen from the beverage, prevent oxidation and deterioration, and extend the shelf life, thus achieving a highly efficient denitrification effect.

[0034] By setting up a floating assembly 3, a filter plate 34 is installed on a lead screw 33 via a threaded connection, and a drive motor 31 capable of forward and reverse rotation is connected to the top of the transmission rod 32. During the denitrification process, the drive motor 31 rotates forward and backward at a speed of 10-15 rpm, driving the filter plate 34 to move slowly up and down at a speed of 0.5-1 cm / s to promote nitrogen release. After denitrification is completed, the drive motor 31 rotates forward at high speed, causing the filter plate 34 to rise rapidly to the upper part of the tank 1 to achieve solid-liquid separation. Then, it continues to rotate forward, driving the filter plate 34 to rise to the top of the tank 1. The regulating cylinder 12 is opened to lift the cover 4, and the pulp particles on the filter plate 34 can be manually scraped off with tools such as scrapers, conveniently discharging the residue. This solves the problem of microbial growth caused by residue retention in traditional devices and achieves the effect of convenient residue discharge.

[0035] Example 2

[0036] In order to achieve centralized discharge of liquid and to carry out denitrification operations, such as Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, a discharge valve 14 is installed at the bottom front of the tank body 1, and a limit rib 13 is fixedly installed in a ring array on the inner wall of the tank body 1.

[0037] In the design, the liquid is discharged in a concentrated manner through the discharge valve 14 at the bottom of the tank 1, and the vertical guidance constraint of the filter plate 34 during movement is achieved through the annular limiting rib 13 on the inner wall.

[0038] Furthermore, a first mounting hole 42 is provided in the middle of the top of the cover 4, and the bearing 421 is embedded in the first mounting hole 42. A second mounting hole 43 is provided on one side of the top of the cover 4, and an exhaust pipe 431 is connected to the second mounting hole 43.

[0039] In the design, the gas inside the tank is discharged in a directional manner through the exhaust pipe 431 at the top of the cover 4, and the rotating parts are stably supported through the cooperation of the bearing 421 and the transmission rod 32.

[0040] Furthermore, a spiral hose 21 is connected to one end of the exhaust pipe 431 away from the cover 4, and the other end of the spiral hose 21 is connected to the air inlet of the suction device 2.

[0041] In the design, the continuous air extraction function of the tank 1 is realized through the flexible connection of the spiral hose 21, and the negative pressure environment is quickly established through the connection of the exhaust pipe 431 and the air extraction device 2.

[0042] Furthermore, the cylinder body of the adjusting cylinder 12 is fixedly connected to the outer wall of the cover 4 via a connecting bracket, and the piston end of the adjusting cylinder 12 is fixedly connected to the outer wall of the tank 1 via a connecting bracket.

[0043] In the design, the cover 4 is raised and lowered smoothly by adjusting the double-end connection structure of the cylinder 12, and the high-pressure sealing effect is achieved by matching the sealing ring 41 with the inner diameter of the tank 1.

[0044] Example 3

[0045] To achieve vertical motion constraint of the filter plate, such as Figure 2 and Figure 3 As shown, in this embodiment, the outer diameter of the filter plate 34 is adapted to the inner diameter of the tank 1, and the outer side of the filter plate 34 is provided with a limiting groove 341 that matches the limiting ridge 13 in a ring array.

[0046] In the design, the vertical movement constraint of the filter plate 34 is achieved by the engagement of the limiting groove 341 on the outer side of the filter plate 34 with the limiting ridge 13, and the full-section filtration effect is achieved by the adaptation of the outer diameter of the filter plate 34 with the inner diameter of the tank 1.

[0047] Furthermore, a drive motor 31 is connected to the top of the transmission rod 32. The drive motor 31 is fixedly installed on the upper surface of the cover 4 and can rotate in both directions.

[0048] In the design, the bidirectional motion function of the filter plate 34 is realized by controlling the forward and reverse rotation of the drive motor 31, and the stable transmission of rotational motion is realized by the cooperation between the lead screw 33 and the rectangular hole of the transmission rod 32.

[0049] When using this utility model, by adjusting the piston rod of cylinder 12 to extend, the cover 4 is raised to the highest position, and the fruit pulp beverage to be processed is injected through the top opening of the can 1. The liquid level is controlled at 2 / 3 of the volume of the can 1. The cover 4 is then closed, so that the sealing ring 41 is tightly fitted with the inner wall of the can 1 to form a seal.

[0050] Start the air extraction device 2, and extract air from the tank through the exhaust pipe 431 and the spiral hose 21. Continue to extract air for 3-5 minutes to create a negative pressure environment of 0.05-0.08MPa inside the tank. During the extraction process, the drive motor 31 rotates in both directions at a speed of 10-15rpm, driving the transmission rod 32 and the lead screw 33 to rotate, causing the filter plate 34 to move up and down slowly at a speed of 0.5-1cm / s, promoting the release of nitrogen.

[0051] After denitrification is completed, the pumping device 2 is stopped and the exhaust pipe valve 431 is closed. The drive motor 31 is switched to high-speed forward rotation at 30-40 rpm, causing the filter plate 34 to rise rapidly to the upper part of the tank 1. The fruit pulp particles in the fruit pulp beverage are intercepted by the filter plate 34, and the liquid enters the lower area through the filter holes, thus achieving solid-liquid separation.

[0052] The drive motor 31 continues to rotate forward, driving the filter plate 34 to rise to the top of the tank 1 at a speed of 2-3 cm / s, and the regulating cylinder 12 is opened to lift the cover 4. The pulp particles on the filter plate 34 are manually scraped off with the help of scrapers and other tools.

[0053] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
