Description

Technical Field

[0001] The invention relates to the technical field of grain pulverizing, and in particular to an anti-sedimentation type pulverizing device for grain flour processing. Background Art

[0002] Grain crushing equipment is a device used to crush grains into powder particles. It is widely used in the field of food processing. The working principle of grain crushing equipment is to impact the grains with a high-speed rotating hammer or blade to crush the grains, and then screen them through a screen. The grain particles passing through the screen are qualified products. During the operation of existing grain crushing equipment, since the crushing hammer or blade performs high-speed circular motion and there is air in the crushing area, a circulation layer will be generated in the crushing area. This circulation layer will limit the movement trajectory of the grains, causing part of the grains to stay in the crushing area for a long time, making the grain particles after crushing too small, reducing product quality. At the same time, the existence of the circulation layer also leads to additional grain circulation, which increases energy consumption. Summary of the invention

At the same time, the "spiral" motion of the hammer piece is used to reduce the degree of formation of the circulation layer, and the appearance of the circulation layer is prevented from limiting the movement trajectory of the grains, resulting in the inability to timely remove the crushed grains from the crushing area, thereby causing the grains to be over-crushed and reducing the crushing quality. The support piece is used to drive the hammer piece to move together through the sliding rod, thereby increasing the distance between the hammer piece and the screen, thereby increasing the particle size of the crushed grains, thereby improving the application range of the equipment.

DETAILED DESCRIPTION

[0017] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] like Figure 1 , Figure 2 and Figure 6 As shown, an embodiment of the present invention is proposed, which provides an anti-sedimentation pulverizing equipment for grain powder processing, which is used to solve the problem of the existence of a circulating layer in the existing grain pulverizing process, thereby increasing energy consumption and reducing pulverizing efficiency. The equipment includes: a frame 1; a shell 2, which is fixedly connected to the frame 1, and the upper and lower sides of the shell 2 are respectively provided with a feed shell and a discharge port; two support frames 3, which are symmetrically distributed and fixedly connected to the frame 1; a rotating shaft 4, which is rotatably connected between the two support frames 3, and the frame 1 is equipped with a motor 5, and the output shaft of the motor 5 is connected to the rotating shaft 4 through a pulley belt transmission; a screen 6, which is fixedly connected to the shell 2 through a cross bar, and the screen 6 is provided with a trapezoidal protrusion for changing the movement trajectory of the material in the shell 2; a crushing mechanism, which is arranged in the shell 2, and is used to crush the material; an extrusion mechanism, which is arranged on one of the support frames 3, and is used to change the crushing area of ​​the shell 2.

[0019] In the above scheme, the screen 6 has a plurality of trapezoidal protrusions distributed at intervals, which are used to make the distance between the crushing area and the screen 6 "variable", so that the circulation layer appearing in the crushing area is effectively destroyed within a certain range, thereby destroying the specific movement trajectory of the grain, increasing the degree of disorder of the grain, and preventing the grain from staying in the crushing area for too long, resulting in the grain particles being too small after the crushing is completed, reducing the product quality (and increasing the intensity of the grain movement, thereby preventing the grain from being deposited on the screen 6). At the same time, the screen 6 with the trapezoidal protrusions also plays a role similar to a tooth plate, so that the grain in the crushing area is easier to crush, and the crushed small particles can be quickly discharged to the outside of the screen 6, thereby improving the crushing efficiency. When the present device is used to crush the grain, the motor 5 drives the rotating shaft 4 to rotate, so that the crushing mechanism works, and then the grain is poured into the shell 2 through the feed shell, the crushing mechanism impacts and crushes the grain, and then the screen 6 is used to screen the grains of large and small particles. The grains that reach the required particle size are discharged from the screen 6 and then discharged from the equipment through the discharge port, and the grains that do not reach the required particle size remain in the shell 2 and are continuously crushed.

[0020] like Figure 2-Figure 5 As shown, the crushing mechanism includes: two rotating frames 701 distributed on the left and right, both of which are rotatably connected to the shell 2, and the rotating frames 701 are fixedly connected to the rotating shaft 4; a plurality of support members 702 are distributed at intervals and are respectively arranged on adjacent rotating frames 701; a plurality of sliding rods 703 are distributed at intervals and are respectively spline-connected between two adjacent support members 702 on different rotating frames 701; a plurality of hammer pieces 704 are distributed at intervals and are respectively fixedly connected to adjacent sliding rods 703, and the hammer pieces 704 are folded to facilitate throwing the material onto the screen 6.

[0021] In the above scheme, the rotating frame 701 is made of alloy material, which is used to reduce its own rotational inertia while ensuring strength. The hammer 704 is made of stainless steel to increase its ability to resist external erosion, thereby preventing the by-products produced by oxidation from affecting the quality of the grain after crushing. During the rotation of the rotating shaft 4, the rotating shaft 4 drives the two rotating frames 701 to rotate together, and the rotating frame 701 drives the sliding rod 703 to rotate together through the support 702, and the sliding rod 703 drives the hammer 704 to rotate together. When the hammer 704 contacts the grain, the hammer 704 impacts the grain and crushes it. Since the wing-shaped hammer 704 can generate stronger centrifugal force during rotation, this helps to scatter the crushed fine particles around the crushing area to achieve more uniform dispersion. At the same time, the wing-shaped hammer 704 can drive the grain to flow and move more fully, thereby reducing the probability of accumulation and blockage of grain particles in the crushing area.

[0022] like Figure 2-Figure 5As shown, the extrusion mechanism includes: an extrusion member 801, which is rotatably connected to one of the support frames 3, and the extrusion member 801 is provided with an arc surface, which is wavy and used to make the support member 702 and the sliding rod 703 slide continuously relative to each other, and the sliding rod 703 is extruded and matched with the arc surface on the extrusion member 801, and a ball is connected to one end of the sliding rod 703 close to the extrusion member 801, and the ball is used to reduce the friction between the extrusion member 801 and the extrusion member 801; a gear ring 802, which is fixedly connected to the extrusion member 801; a movable sleeve 803, Slidingly and rotatably connected to the extrusion member 801; the first gear 804 and the second gear 805 are both rotatably connected to the shell 2, the first gear 804 and the gear ring 802 are meshed, and the first gear 804 and the second gear 805 are fixedly connected via a connecting sleeve; the third gear 806 is rotatably connected to the shell 2 via a supporting ring, the third gear 806 is meshed with the second gear 805, the sliding rod 703 is limitedly matched with the third gear 806, and a first elastic element 807 is fixedly connected between the support member 702 and the sliding rod 703.

[0023] In the above scheme, the extrusion member 801 is circular, and the wavy surface on the extrusion member 801 is a closed loop type, which is used to make the rotating frame 701 and the support member 702 slide continuously relative to each other, and the tooth number ratio between the first gear 804 and the ring gear 802 is smaller than the tooth number ratio between the second gear 805 and the third gear 806, which is used to make the extrusion member 801 and the third gear 806 rotate relative to each other, and the first elastic element 807 is a spring, which is used to reset the sliding rod 703. During the rotation of the sliding rod 703, the sliding rod 703 drives the third gear 806 to rotate together, and the third gear 806 drives the second gear 805 to rotate together, and the second gear 805 drives the first gear 804 to rotate together through the connecting sleeve, and the first gear 804 drives the extrusion member 801 to rotate together through the ring gear 802. During the process There is a speed difference between the extrusion piece 801 and the third gear 806, that is, the two rotate relative to each other, and the sliding rod 703 and the extrusion piece 801 move relative to each other, that is, the ball on the sliding rod 703 begins to roll along the wavy surface on the extrusion piece 801, and under the extrusion of the wavy surface on the extrusion piece 801, the sliding rod 703 and the support piece 702 slide relative to each other, and the sliding rod 703 drives the hammer 704 to move together, thereby changing the crushing area of ​​the hammer 704 in the shell 2, so that the grains are evenly crushed in the shell 2, thereby improving the crushing effect of the grains, and at the same time, the "spiral" motion of the hammer 704 is used to reduce the degree of formation of the circulation layer, to prevent the appearance of the circulation layer from limiting the movement trajectory of the grains, resulting in the inability of the crushed grains to be removed from the crushing area in time, thereby causing the grains to be over-crushed and reducing the crushing quality.

[0024] like Figure 2-Figure 5As shown, it also includes: two rotating sleeves 901, which are symmetrically distributed on the left and right, and are respectively connected to the adjacent support frames 3 in a limited sliding manner; two movable sleeves 803 are symmetrically distributed on the left and right, and the movable sleeves 803 are connected to the adjacent rotating sleeves 901 in a limited rotating manner; the support member 702 is slidably connected to the adjacent rotating frame 701; two threaded sleeves 902, which are symmetrically distributed on the left and right, and are respectively threadedly connected to the adjacent rotating sleeves 901; an adjusting rod 903 is arranged between the two threaded sleeves 902, and an intermediate rod 904 is hinged between the support member 702 and the adjacent movable sleeve 803.

[0025] In the above scheme, the threaded sleeve 902 is connected to the adjusting rod 903 by a one-way bearing, and the type of the one-way bearing can be adjusted according to actual conditions (this technology is existing technology and will not be described in detail here). When it is necessary to obtain grain particles with a larger particle size, the adjusting rod 903 is deflected downward, and the adjusting rod 903 drives the threaded sleeve 902 to deflect together through the one-way bearing. Under the action of the two threaded sleeves 902, the two rotating sleeves 901 begin to move back to back, and the rotating sleeve 901 slides relatively with the support frame 3. The rotating sleeve 901 drives the moving sleeve 803 to move together, and the moving sleeve 803 pulls the support member 702 through the intermediate rod 904. The support member 702 slides relatively with the rotating frame 701, and the support member 702 drives the hammer 704 to move together through the sliding rod 703, thereby increasing the distance between the hammer 704 and the screen 6, thereby increasing the particle size of the grain after crushing, thereby improving the application range of the present device.

[0026] like Figure 6 As shown, it also includes: a fixed rod 1001, fixedly connected between the two rotating frames 701; a plurality of rotating plates 1002, which are distributed at intervals and fixedly connected to the fixed rod 1001, and the screen 6 is a "semi-elliptical" shape, and the rotating plates 1002 are in contact with the screen 6.

[0027] In the above scheme, the rotating plate 1002 is inclined to tumble the grains. During the rotation of the rotating frame 701, the rotating frame 701 drives the rotating plate 1002 to rotate together through the fixed rod 1001. The fixed rod 1001 pushes the grains in the adjacent area upward, so that the grains accumulated at the bottom of the screen 6 due to gravity are tumbled, and then the grains are captured by the hammer 704 again and regain the centrifugal force, so that the crushed grains can be smoothly discharged from the screen 6.

[0028] like Figure 1 , Figure 6 and Figure 7As shown, it also includes: two connecting blocks 1101, which are symmetrically distributed and fixedly connected to the shell 2; a plurality of U-shaped tubes 1102, which are respectively fixedly connected to adjacent connecting blocks 1101, the U-shaped tubes 1102 are filled with transmission medium, the U-shaped tubes 1102 are slidably connected to two piston plates 1103, and the shell 2 and the connecting blocks 1101 are respectively fixedly connected to the adjacent piston plates 1103 with second elastic elements 1104.

[0029] In the above scheme, the transmission medium in the U-shaped tube 1102 is hydraulic oil, and the second elastic element 1104 is a spring, which is used to reset the adjacent piston plate 1103. During the rotation of the rotating plate 1002, when the rotating plate 1002 rotates to contact the screen 6, the rotating plate 1002 drives the screen 6 to move together, and the screen 6 stretches (compresses) the second elastic element 1104, and when the rotating plate 1002 is separated from the screen 6, the rotating plate 1002 is reset and vibrates under the action of the second elastic element 1104, thereby facilitating the passage of grain particles on the screen 6.

[0030] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
