Abstract
Description
Technical Field
[0001] The utility model relates to a stirring tank, in particular to a horizontal stirring device. Background Art
[0002] In the hot pot base, sauce and other industries, the materials are fixed materials and oil or solid materials and liquid materials, which have the physical property of being easily stratified when standing still. A stirring device is needed to stir the materials to make the solid and liquid evenly distributed. For example, in the hot pot base industry, the boiled base enters the horizontal mixing tank, and the base is made uniform by the stirring device, and then pumped to the filling machine for canning and packaging.
[0003] The current situation is that the stirring device in the horizontal mixing tank is of the screw type, which produces a unidirectional or bidirectional propulsion force on the material and has a certain stirring and mixing effect, but the propulsion force is axial, and the mixing effect on solids and liquids is limited. After half of the material in the tank is transported, the solid content in the bottom material is much less, resulting in uneven solid content in the finished product; another situation is that the material in the tank is not put cleanly, and there are solid and liquid bottom materials remaining.
[0004] The problems that need to be solved are: 1. During the discharge process of the horizontal mixing tank, the solid and liquid are not mixed evenly, resulting in a large amount of solid materials being discharged in the early stage and more liquid materials in the later stage. 2. The materials in the tank are not discharged cleanly, and there are solid and liquid bottom materials remaining. Utility Model Content
[0005] The utility model aims to provide a horizontal stirring device to solve the problem of uneven solid-liquid mixing in the existing horizontal stirring tank.
[0006] The utility model is implemented as follows: a horizontal stirring device comprises a tank body, a rotating shaft is horizontally arranged in the tank body, screw belts with opposite rotation directions are respectively arranged on the left and right sections of the rotating shaft, a discharge port is opened at the middle position of the bottom of the tank body, a plurality of scrapers are arranged on the rotating shaft along the length direction of the rotating shaft, and the scrapers are staggered and distributed on both sides of the rotating shaft, and the inclination direction of the scrapers is consistent with the inclination direction of the screw belts corresponding to their positions.
[0007] The spiral belt is connected to the rotating shaft through a first connecting rod, and the scraper is connected to the rotating shaft through a second connecting rod. The distance from the outer edge of the scraper to the center of the rotating shaft is the same as the distance from the outer edge of the spiral belt to the center of the rotating shaft.
[0008] The bottom of the tank is a semicircular shell.
[0009] The angle between the scraper plate surface and the axis of the rotating shaft is 45°.
[0010] The bottom of the tank body is inclined downward from the left and right sides to the middle.
[0011] The tank body comprises an inner liner, a heat-insulating layer and an outer protective layer, and a jacket is arranged between the inner liner and the heat-insulating layer at the bottom of the tank body.
[0012] A reduction motor is arranged at one end of the tank body, and the reduction motor is connected to the rotating shaft.
[0013] A top cover is arranged on the top of the tank body, and the top cover comprises a fixed cover located in the middle and movable covers located on the left and right sides of the fixed cover, and a protective net is arranged below the movable cover.
[0014] The outer end edge of the scraper is arc-shaped.
[0015] The left and right sections of the spiral belt overlap at the middle position of the rotating shaft.
[0016] The horizontal stirring device of the utility model has two spiral ribbons with opposite rotation directions and multiple scrapers. When rotating, the spiral ribbon provides axial thrust, and the radial thrust generated by the spiral ribbon is very small. The inclined scraper and the axial thrust also generate radial thrust. When rotating, the spiral ribbon cooperates with the scraper to achieve uniform stirring of the material. When the shaft rotates forward, the two spiral ribbons push the material to the middle, and the scraper pushes the material to both sides, so as to achieve uniform solid and liquid (uniform up and down, uniform left and right); when the stirring shaft is reversed, the two spiral ribbons push the material to both sides, and the scraper pushes the material to the middle, so as to achieve uniform solid and liquid (uniform up and down, uniform left and right). By adding the scraper stirring, the radial thrust is increased, so that the solid material can roll up. The axial thrust of the spiral ribbon is opposite to the axial thrust of the scraper, so that the solid material can circulate without accumulation. After adopting the utility model, solids and liquids can be effectively mixed, so that the solid-liquid ratio in the output material remains stable. At the same time, the left and right sides of the bottom of the semicircular tank body are inclined to the middle, so that the material can be completely discharged without material residue.

DETAILED DESCRIPTION
[0026] The specific implementation of the utility model will be further described below in conjunction with the accompanying drawings.
[0027] like Figures 1 to 6 As shown, the utility model includes a tank body 1, which is a horizontal tank body 1, and its length direction is horizontal. A rotating shaft 2 is horizontally arranged in the tank body 1, and both ends of the rotating shaft 2 are installed on the tank body 1 through bearing seats. The rotating shaft 2 is divided into two symmetrical left and right sections, and screw belts 3 are respectively arranged on the left and right sections of the rotating shaft 2, and the two screw belts 3 are symmetrical about the center of the rotating shaft 2, so the rotation directions of the two screw belts 3 are opposite. A discharge port 7 is opened at the middle position of the bottom of the tank body 1, and a plurality of scrapers 4 are arranged on the rotating shaft 2 along the length direction of the rotating shaft 2, and the scrapers 4 are staggered on both sides of the rotating shaft 2, and the inclination direction of the scrapers 4 is consistent with the inclination direction of the screw belt 3 corresponding to the position where the scrapers 4 are located.
[0028] The spiral belt 3 is connected to the rotating shaft 2 through a first connecting rod 5, and the scraper 4 is connected to the rotating shaft 2 through a second connecting rod 6. The distance from the outer edge of the scraper 4 to the center of the rotating shaft 2 is the same as the distance from the outer edge of the spiral belt 3 to the center of the rotating shaft 2.
[0029] The first connecting rod 5 and the second connecting rod 6 are both perpendicular to the surface of the rotating shaft.
[0030] The two screw belts 3 are connected to the shaft 2 as an integral structure through a plurality of first connecting rods 5. When the shaft 2 rotates, the two screw belts 3 rotate together with the shaft 2. Since the rotation directions of the two screw belts 3 are opposite, the screw belts 3 generate thrust from the middle to the two ends or from the two ends to the middle. Figure 7 , Figure 8 shown.
[0031] The inclined scraper 4 is used to generate axial thrust and radial thrust. Multiple scrapers 4 are distributed along the length direction of the rotating shaft 2, and the multiple scrapers 4 are symmetrical about the center of the rotating shaft 2, so that the number of scrapers 4 corresponding to each spiral belt 3 is consistent. For example, in this specific embodiment, each spiral belt 3 corresponds to four scrapers 4.
[0032] The spiral ribbon 3 is spirally wound around the rotating shaft 2. If there is a spiral ribbon 3 on one side of a certain position of the rotating shaft 2, there is no spiral ribbon 3 on the other side of the rotating shaft 2 at this time, and the scraper 4 is arranged on the side of the position without the spiral ribbon 3, and at this position, the inclination direction of the scraper 4 is consistent with the inclination direction of the spiral ribbon 3, but because the scraper 4 and the spiral ribbon 3 are respectively located on both sides of the rotating shaft 2, when the rotating shaft 2 rotates, the axial thrusts generated by the spiral ribbon 3 and the scraper 4 corresponding to this position are opposite, and at the same time, the scraper 4 also generates a radial outward thrust.
[0033] Two adjacent scrapers 4 can be at any angle in the circumferential direction of the shaft 2, but in order to make the scrapers 4 more evenly distributed and maximize the efficiency of the scrapers 4 in generating thrust, it is best to stagger the scrapers 4 on both sides of the shaft 2. Since the scrapers 4 are staggered on both sides of the shaft 2, the spacing between two adjacent scrapers 4 is exactly half of the pitch, and the inclination directions of the spiral belts 3 corresponding to the positions of the two adjacent scrapers 4 are opposite, so the inclination directions of the two adjacent scrapers 4 are also opposite.
[0034] Specific as Figure 7 As shown in FIG. 1 , when the shaft 2 rotates forward, the spiral belt 3 generates an axial thrust from both ends to the middle, and the scraper 4 generates an axial thrust from the middle to both ends and an outward radial thrust; Figure 8 As shown, when the shaft 2 is reversed, the spiral belt 3 generates an axial thrust from the middle to both ends, and the scraper 4 generates an axial thrust from both ends to the middle and an outward radial thrust. The scraper 4 generates opposite axial thrusts to the spiral belt 3, and at the same time increases the radial thrust, so that the solid material can roll up, and the solid material can form a cycle without accumulation, thereby ensuring the uniformity of solid-liquid mixing during stirring.
[0035] Since the material can maintain the uniformity of solid-liquid mixing, the solid-liquid content of the material output first and the material output later can remain consistent, which can ensure the uniform solid content of the filled finished product.
[0036] The angle between the scraper 4 and the axis of the rotating shaft 2 is specifically 45°.
[0037] The outer edge of the scraper 4 is arc-shaped.
[0038] The left and right sections of the spiral belt 3 overlap in a middle portion of the rotating shaft 2 , and the overlapping portion is located above the discharge port 7 .
[0039] In order to facilitate stirring, the bottom of the tank body 1 is a semicircular shell, and the inner wall diameter of the semicircular shell is slightly larger than the diameter of the spiral belt 3. The material gathers at the bottom of the tank body 1. No matter how much remaining material there is, the material can be stirred by the spiral belt 3 and the scraper 4.
[0040] In addition, the bottom of the tank body 1 is inclined downward from the left and right sides to the middle, so that a small amount of material at the bottom of the tank body 1 can flow along the inclined surface toward the discharge port 7 in the middle, which can avoid material residue and enable the material to be completely discharged.
[0041] The side wall of the tank body 1 includes an inner liner 1-1, an insulation layer 1-2 and an outer protective layer 1-3. A jacket 1-4 is provided between the inner liner 1-1 and the insulation layer 1-2 at the bottom of the tank body 1. Materials such as hot pot soup base need to maintain a certain temperature during the mixing and filling process. The hot pot soup base is easy to solidify under low temperature conditions, which makes it impossible to mix evenly and also affects the filling. Therefore, the material in the tank body 1 is heated by the jacket 1-4 to maintain the temperature of the material and prevent it from solidifying. A hot water inlet 10 is provided at the bottom of the tank body 1, and a hot water outlet 11 is provided at the upper part of the tank body 1. Hot water enters from the bottom and passes through the jacket 1-4 and is discharged from the top to achieve heating of the material. At the same time, the tank body 1 is insulated by the insulation layer 1-2 to reduce the loss of heat inside the tank body 1.
[0042] A reduction motor 8 is provided at one end of the tank body 1, and the reduction motor 8 is connected to the rotating shaft 2. The reduction motor 8 drives the rotating shaft 2 to rotate. The speed can be adjusted by the reduction motor 8, and the forward and reverse rotation of the rotating shaft 2 can be realized, so that the material in the tank body 1 can be stirred as needed.
[0043] A top cover is provided on the top of the tank body 1, and the top cover covers the top of the tank body 1. The top cover includes a fixed cover 13 in the middle and movable covers 14 on the left and right sides of the fixed cover 13. The movable cover 14 is hingedly connected to the fixed cover 13 and can be opened upward. To ensure safety, a protective net 15 is provided below the movable cover 14. A feed port 12 is provided on the fixed cover 13, and the solid-liquid mixture is injected into the tank body 1 through the feed port 12 on the fixed cover 13.
[0044] Support legs 9 are provided below the tank body 1 to support the tank body 1 .
[0045] The utility model can effectively mix solid and liquid, so that the solid-liquid ratio in the output material remains stable. At the same time, the left and right sides of the bottom of the semicircular tank body 1 are inclined toward the middle, so that the material can be completely discharged without any material residue.
