[0002] During the brewing process, it is necessary to remove the lees.

[0003] Publication No. CN109453862A, Publication Date 2019.03.12, discloses a brewing lees removal device, including a machine housing, a pulping cylinder on the machine housing, a rotating shaft inside the pulping cylinder, a cutter disc sleeved on the rotating shaft, a pulp inlet on one side of the pulping cylinder, a motor on the other side, the output shaft of the motor being connected to the rotating shaft, a light lees outlet at the top of the pulping cylinder, a scooping net at the light lees outlet, a screen plate between the pulping cylinder and the machine housing, the screen plate slidingly engaging with the machine housing and the pulping cylinder, a swing seat at the bottom of the machine housing, and a drive device for driving the swing seat to swing left and right.

[0004] In the prior art, including the aforementioned patent, since the slag discharge pipe is located on one side of the slag removal box wall, and the heavy impurity particles are large, the slag discharge pipe is prone to blockage during slag discharge, resulting in low slag removal efficiency and unsmooth slag discharge. Utility Model Content

[0005] The purpose of this utility model is to provide a lees removal device for brewing, which solves the technical problem in the prior art that, because the lees discharge pipe is located on one side of the lees removal box wall, and the heavy impurity particles are large, the lees discharge pipe is prone to blockage during lees discharge, resulting in low lees removal efficiency and unsmooth lees discharge.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for removing lees from brewing lees, comprising:

[0007] The slag removal box is used for removing slag from the lees during the settling and stratification process.

[0008] The slag discharge pipe is located at the bottom of one side wall of the slag removal box and is connected to the inside of the slag removal box.

[0009] The elastic element is evenly distributed on the inner wall of the slag discharge pipe in a circumferential direction, and forms a pressure regulating cavity between itself and the inner wall of the slag discharge pipe. The pressure inside the pressure regulating cavity changes periodically, causing the elastic element to bulge and deform periodically, so as to periodically expel the slag material inside the slag discharge pipe by radial extrusion.

[0010] Preferably, when the air pressure inside the air pressure regulating chamber is in a negative pressure state, the elastic element is concave and deformed to form a low-pressure zone inside the slag discharge pipe.

[0011] Preferably, the elastic element includes a first arc-shaped portion and a second arc-shaped portion, wherein the length of the first arc-shaped portion is greater than that of the second arc-shaped portion.

[0012] Preferably, the slag discharge pipe has an annular cavity inside its wall that communicates with the air pressure regulating chamber.

[0013] Preferably, an air cylinder communicating with the annular cavity is fixedly installed on one side wall of the slag removal box, and an electric actuator is coaxially mounted on the top of the air cylinder.

[0014] Preferably, the air cylinder is provided with a piston plate that moves along the central axis of the air cylinder, and the piston plate is fixedly connected to the output end of the electric actuator.

[0015] In the above technical solution, the brewing lees removal device provided by this utility model has the following beneficial effects:

[0016] This invention utilizes an elastic element to open the valve for slag discharge during the slag removal process. Simultaneously, the air pressure inside the regulating chamber is periodically adjusted. When the air pressure inside the regulating chamber increases, the elastic element bulges and deforms, thereby periodically radially compressing the slag material entering the slag discharge pipe. Under the radial compression of the elastic element, the slag material moves along the arc of the elastic element towards the slag discharge port of the slag discharge pipe and is smoothly discharged, effectively reducing the probability of blockage during slag discharge and making slag discharge smoother, thus improving slag removal efficiency.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1-5 As shown, a device for removing lees from brewing mash includes:

[0027] Descum removal box 1 is used for removing scum from the lees after they have been left to stand and layer.

[0028] The slag discharge pipe 4 is located at the bottom of one side wall of the slag removal box 1 and communicates with the inside of the slag removal box 1.

[0029] The elastic element 8 is evenly distributed in an arc shape on the inner wall of the slag discharge pipe 4, and forms a pressure regulating cavity between itself and the inner wall of the slag discharge pipe 4. The air pressure inside the pressure regulating cavity changes periodically, causing the elastic element 8 to bulge and deform periodically, so as to periodically expel the slag material inside the slag discharge pipe 4 by radial extrusion.

[0030] Specifically, open the top cover of the crushing cylinder at the top of the slag removal box 1, pour the lees into the crushing cylinder, close the top cover, and start the motor at the top of the top cover. This will drive the rotating shaft fixed at the output end of the motor to rotate, thereby driving the cutter discs arrayed on the rotating shaft to rotate synchronously, thus crushing the lees. The slurry flows into the slag removal box 1 through the crushing cylinder and settles into layers. Light impurities float on the top of the slurry, while heavy impurities settle at the bottom of the slag removal box 1, and are discharged in sequence to achieve layered slag removal and improve the slag removal quality.

[0031] Furthermore, since the slag discharge pipe 4 is located on one side of the slag removal box 1, and the heavy impurity particles are relatively large, the slag discharge pipe 4 is prone to blockage during slag discharge, resulting in low slag removal efficiency and unsmooth slag discharge. By using the elastic element 8, the valve is opened to discharge slag during slag discharge. At the same time, the air pressure inside the air pressure regulating chamber changes periodically. When the air pressure inside the air pressure regulating chamber increases, the elastic element 8 bulges and deforms, thereby periodically radially squeezing the slag material entering the slag discharge pipe 4. Under the radial squeezing of the elastic element 8, the slag material moves along the arc surface of the elastic element 8 to the slag discharge port of the slag discharge pipe 4 and is smoothly discharged, effectively reducing the probability of blockage during slag discharge of the slag discharge pipe 4, making slag discharge smoother, and thus improving slag removal efficiency.

[0032] It should be noted that the air pressure inside the air pressure regulating chamber can be adjusted by an air pump, a piston cylinder, or other technical means known to those skilled in the art.

[0033] As a further embodiment of this utility model, when the air pressure inside the air pressure regulating chamber is in a negative pressure state, the elastic element 8 is concave and deformed to form a low-pressure zone inside the slag discharge pipe 4.

[0034] Specifically, when the air pressure inside the air pressure regulating chamber is in a negative pressure state, the elastic element 8 is concave and deformed, such as... Figures 4 to 3 As shown, the cross-sectional area of ​​the discharge channel composed of elastic elements 8 inside the slag discharge pipe 4 is increased, and the cavity volume is increased, thereby forming a low-pressure zone in the discharge channel. This allows the slag at the bottom of the slag removal box 1 to be extracted, enabling the slag to enter the discharge channel quickly and smoothly. When the air pressure inside the air pressure regulating chamber increases, the elastic elements 8 bulge and deform, thereby radially squeezing the slag entering the discharge channel. Under the radial squeezing of the elastic elements 8, the slag moves along the arc surface of the elastic elements 8 to the slag outlet of the slag discharge pipe 4 and is smoothly discharged, thus realizing periodic suction and discharge. Through low-pressure suction, blockage is further prevented, rapid discharge is achieved, and the slag removal efficiency is effectively improved.

[0035] As a further embodiment of the present invention, the elastic member 8 includes a first arc-shaped portion 81 and a second arc-shaped portion 82, wherein the length of the first arc-shaped portion 81 is less than that of the second arc-shaped portion 82.

[0036] Specifically, the first arc-shaped portion 81 is located near the slag inlet, and the second arc-shaped portion 82 is located near the slag outlet. Since the length of the first arc-shaped portion 81 is less than that of the second arc-shaped portion 82, when the elastic element 8 protrudes and deforms, as... Figure 5 As shown, a Venturi discharge channel is formed. The cross-sectional area of ​​the discharge channel located in the first arc-shaped part 81 gradually decreases from the slag inlet to the middle, and the cross-sectional area of ​​the discharge channel located in the second arc-shaped part 82 gradually decreases from the slag outlet to the middle. Thus, during discharge, a negative pressure is formed in the middle. When the elastic element 8 protrudes and deforms, it radially squeezes the slag. Following the principle that the flow velocity is small where the cross-section is large and the flow velocity is large where the cross-section is small, the slag moves from the middle to both sides along the inner wall of the elastic element 8, and the amount of slag discharged is greater than the amount of slag returned, thereby achieving rapid slag discharge and further improving slag removal efficiency.

[0037] As a further embodiment of this utility model, an annular cavity 7 is provided inside the wall of the slag discharge pipe 4, which is connected to the air pressure regulating cavity.

[0038] As a further embodiment of this utility model, an air cylinder 3 that communicates with the annular cavity 7 is fixedly installed on one side wall of the slag removal box 1, and an electric actuator 2 that is coaxially installed on the top of the air cylinder 3.

[0039] As a further embodiment of this utility model, a piston plate 5 is provided inside the air cylinder 3 and is movable along the central axis of the air cylinder 3. The piston plate 5 is fixedly connected to the output end of the electric push rod 2.

[0040] Specifically, by activating the electric actuator 2, the piston plate 5 is driven to move back and forth inside the air cylinder 3, thereby periodically adjusting the air pressure inside the air cylinder 3. This periodically pumps and pumps air into the annular cavity 7, and periodically pumps or pumps air into the air pressure regulating cavity, causing the elastic plate 8 to periodically bulge or dent and deform. There is no need to configure a drive source for each air pressure regulating cavity, which effectively simplifies the structure and saves manufacturing costs.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
