This type of device is widely used in the food, chemical, and pharmaceutical industries, particularly in the processing of starch, granular materials, and other powdered materials. Slurrying devices not only increase production efficiency but also improve product consistency and stability, thus playing a vital role in modern industrial production.

[0003] CN201720218944.5 discloses a stirring tank, comprising a base, two opposite brackets vertically fixed on the base, a stirring tank body arranged between the two brackets, a first water spray pipe arranged at the top of the side wall of the stirring tank body, a plurality of first water spray heads evenly distributed on the first water spray pipe, a first stirring device arranged in the stirring tank body, a tank cover arranged on the top of the stirring tank body, and a dissolving box arranged on the tank cover; the bottom of the dissolving box is connected to the stirring tank body, a second stirring device is provided in the dissolving box, a feed hopper is provided at the top of the dissolving box, and an agitator is provided at the bottom of the feed hopper; a heating chamber is provided on the outside of the dissolving box, and the heating chamber is respectively connected to the second water inlet pipe and the drain pipe; a second annular water spray pipe is provided on the inside of the tank cover, and a plurality of second water spray heads are provided on the second water spray pipe, and the second water spray heads are evenly distributed in a radiation shape on the second water spray.

[0004] In the above technical solution, the material is fed into the mixing tank by feeding it from the hopper, but the mixing tank cannot control the speed of material feeding. Moreover, because the first stirring device needs to be set at the axial position of the mixing tank, the driving component of the first stirring device will also be located at the axial position.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] refer to Figures 1 to 3A continuous automatic slurrying device includes a stirring kettle, a stirring mechanism 3 extending into the stirring kettle, and a hopper 2. The hopper 2 is located on one side of the stirring mechanism 3. The top of the hopper 2 is provided with a feed inlet 21, and the bottom of the hopper 2 is provided with a discharge port 22 connected to the stirring kettle.

[0030] The hopper 2 has a triangular cross-section in the vertical direction; the side of the cross-section close to the stirring mechanism 3 is a first side 24, and the side of the cross-section away from the stirring mechanism 3 is a second side 25; the angle between the first side 24 and the plumb line is smaller than the angle between the second side 25 and the plumb line;

[0031] A vertically arranged auger 23 is provided in the hopper 2 ; the feed port 21 is located on one side of the auger 23 and away from the stirring mechanism 3 .

[0032] Under this design, a certain amount of water is first added to the stirring tank, then the stirring mechanism 3 is turned on, and then the material is put into the hopper 2, and the material is transported to the stirring tank 1 through the auger 23 vertically arranged in the hopper 2. When there is too much solid material in the stirring tank 1, the auger 23 is stopped, and water is added to the stirring tank 1. After sufficient water is added, the auger 23 is restarted. When there is less solid material in the stirring tank 1, the conveying speed of the auger 23 is increased. Moreover, the cross-section of the hopper 2 in the vertical direction is triangular, and by using a design method in which the angle between the first side 24 and the plumb line is smaller than the angle between the second side 25 and the plumb line, the arrangement of the hopper 2 will not affect the stirring mechanism 3; in this way, the volume of the hopper 2 can be increased without affecting the arrangement of the stirring mechanism 3, thereby increasing the storage capacity of the hopper 2 and improving the utilization rate of space.

[0033] In this embodiment, the angle between the first side 24 and the plumb line is less than 20°; the angle between the second side 25 and the plumb line is 30-60°; the angle between the first side 24 and the plumb line is less than 10°; the angle between the second side 25 and the plumb line is 35-55°.

[0034] In a preferred embodiment, the angle between the first side 24 and the plumb line is 0°, i.e., the first side 24 and the plumb line coincide with each other. In other embodiments, the angle between the first side 24 and the plumb line can be 5°, 10°, or 15°. The angle between the second side 25 and the plumb line can be 30°, 40°, 50°, or 60°. Of course, any value not specified in this embodiment can also be used as long as it is within this range. More preferably, the angle between the first side 24 and the plumb line is less than 10°, and the angle between the second side 25 and the plumb line is set between 35° and 55°.

[0035] Specifically, when the angle between the first side 24 and the plumb line is too large, the hopper 2 will occupy too much space, thereby affecting the arrangement of the stirring mechanism 3. In order to prevent the hopper 2 from affecting the arrangement of the stirring mechanism 3, the angle between the first side 24 and the plumb line is less than 20°. In order to allow the material in the hopper 2 to slide toward the discharge port 22 under the action of its own gravity, the angle between the second side 25 and the plumb line is set in the range of 30 to 60°.

[0036] Preferably, the projection of the hopper 2 on the horizontal plane is a triangle, a semicircle or a polygon with more than 3 sides.

[0037] Furthermore, in order to maximize the area of ​​the feed port 21 and improve space utilization without affecting the arrangement of the stirring mechanism 3, the projection of the horizontal plane of the hopper 2 is set to a triangle, a semicircle or a polygon with more than 3 sides.

[0038] More preferably, the projection of the hopper 2 on the horizontal plane exceeds the edge of the stirring tank. The projection of the hopper 2 on the horizontal plane exceeds the edge of the stirring tank, which can make the space for storing materials in the hopper 2 larger.

[0039] More preferably, the hopper 2 is provided with a bag breaking mechanism 26 for puncturing the ton bag, and the bag breaking mechanism 26 includes a fixed rod 261 connected to the hopper 2, and multiple blades 262 connected to the fixed rod 261. The blades 262 have a knife tip 2621, and the multiple knife tips 2621 converge at the same point to form a puncture tip for puncturing the ton bag.

[0040] The blade tips 2621 of multiple blades 262 are gathered at one point to form a puncture tip for puncturing a ton bag. This can concentrate the applied force on a small area to enhance the puncture effect, and can make the force condition of each blade 262 more uniform, avoiding the blade 262 from bending due to uneven force when puncturing the ton bag.

[0041] Preferably, the stirring mechanism 3 includes a rotary motor 31 disposed above the stirring tank 1, and a stirring rod 32 is provided on the power output end of the rotary motor 31;

[0042] The hopper 2 is arranged on the top of the stirring tank 1 , and a radar level meter 11 and a microwave level meter 12 are also provided on the top of the stirring tank 1 .

[0043] The stirring rod 32 has been disclosed in Chinese patent CN202020474109, so the structure of the stirring rod 32 will not be described in detail in this embodiment.

[0044] Specifically, the rotation of the stirring rod 32 is controlled by the rotating motor 31, so that the material in the stirring tank 1 is stirred and slurried. At the same time, the solid and liquid conditions in the stirring tank 1 can be monitored by the cooperation of the radar level meter 11 and the microwave level meter 12.

[0045] In this embodiment, a water supply pipe 14 is provided on the top of the stirring tank 1 , and a water supply pump 141 is provided on the water supply pipe 14 ; a discharge pipe 13 is provided on the bottom of the stirring tank 1 , and a discharge pump 131 is provided on the discharge pipe 13 .

[0046] Specifically, water is pumped out using the water supply pump 141, and the water enters the mixing tank 1 after passing through the water supply pipe 14, thereby providing water for the mixing tank 1. When the material in the mixing tank 1 needs to be discharged, the discharge pump 131 is turned on to draw out the material in the mixing tank 1, so that the material will flow out from the bottom of the mixing tank 1 and enter the discharge pipe 13, thereby completing the discharge of the material in the mixing tank 1.

[0047] Preferably, the continuous automatic pulping device further includes an electric hoist 4, which is used to move the hoisted ton bag to the bag breaking mechanism 26 so that the ton bag can be punctured. By using the electric hoist 4 to lift the ton bag and hoist it to the bag breaking mechanism 26, the bag breaking mechanism 26 punctures the ton bag so that the material in the ton bag can fall into the hopper 2, thereby improving transportation efficiency.

[0048] Example 2

[0049] refer to Figure 3 In this embodiment, the cross section is a right triangle. Specifically, if the cross section of the hopper 2 is a right triangle, the first side 24 will coincide with the plumb line. Under the action of gravity, the material can flow downward more smoothly. In conjunction with the vertically arranged auger 23, the material in the hopper 2 can be more smoothly transported to the mixing tank 1.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or modifications can be made without departing from the principles of the present invention. These improvements or modifications should also be regarded as the scope of protection of the present invention.
