Description

Technical Field

[0001] The utility model relates to the technical field of food machinery, in particular to a powdery granular material vibration homogenizing conditioner. Background Art

[0002] The process of wheat flour usually includes: wheat selection, moistening, grinding, sieving, grading, etc., so as to produce different semi-finished products and finished products. The semi-finished products are further graded through grinding, sieving (cleaning powder), and flours of similar quality sifted out from different processes are collected together through conveying equipment to obtain finished products and by-products of different grades. After inspection and sifting, they enter the temporary storage warehouse or are directly packaged and stored.

[0003] In the current process, after the wheat is moistened with water, no moisture adjustment is performed in each system. However, the requirements for powder quality are different, and the moisture loss of different powder paths is different, resulting in a large difference in moisture content in the front, middle, and back paths and by-products. Therefore, it is of great significance to develop a device that can adjust the moisture content of powder particles, arrange it at the rear end of each different process of the product and the front end of the inspection screen, so that the finished products or by-products obtained in each process can be selectively adjusted according to their moisture content before entering the inspection screen.

[0004] There are two similar technologies available: 1. The material flows naturally and is sprayed with water without a material-leveling device, resulting in uneven watering of the material, which makes it easy for the powder particles to clump, and there will be food safety problems in the later stage; 2. Auger spraying watering, which is a technology that sprays water on the material and then uses an auger (single auger or double auger) to mix the material. This technology has the disadvantages of easy condensation on the auger wall and is not easy to clean. In addition, it needs to be equipped with a power motor, which has high operating costs and is not easy to maintain.

[0005] Based on the defects of the above technologies, a powdery granular material vibration homogenizing conditioner was developed. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1-Figure 5 As shown, the powdery granular material vibration homogenizing conditioner of the utility model comprises a frame 1, a conditioning bin 2 arranged on the frame 1, and a hopper 3 arranged on the frame 1 and connected to the lower part of the conditioning bin 2. A feed pipe 4 and an upper air supply pipe 5 connected thereto are arranged on the top of the conditioning bin 2. Two feed pipes are arranged, and one upper air supply port is arranged. An air valve can be selectively arranged on the upper air supply port to adjust the amount of air intake; a vibrating hopper 6 is arranged on one side of the conditioning bin 2 near the feed pipe 4, and the blanking end of the vibrating hopper 6 is located below the upper air supply pipe 5. A vibrator 7 for driving the vibration hopper to vibrate is arranged on the outside, and the vibrator is a vibration motor or an electromagnetic vibrator arranged in a protective box. A windshield 8 for separating the feed pipe and the upper air supply pipe is arranged on the inner side of the tempering bin 2. A plurality of water pipes 10 are vertically arranged on the lower side of the inner part of the tempering bin 2 away from the vibration hopper 6. One end of the plurality of water pipes 10 extends out of the tempering bin to form a water inlet, and the other end extends out of the tempering bin to form a sealing arrangement. A plurality of atomizing nozzles 11 are arranged on the water pipes 10. The atomizing nozzles 11 are perpendicular to the material falling surface, and the lower end of the hopper is its outlet.

[0028] Powdered particles of wheat and other cereal products or terminal products enter the conditioner through the feed pipe, and the material falls into the vibrating hopper. Under the action of the vibrator, the material moves forward evenly and straightly for homogenization, and forms a waterfall in the process of uniform material falling. A water pipe is installed on the other side of the lower part of the conditioner in a direction perpendicular to the falling surface of the material. A number of nozzles are installed on the water pipe. The water mist sprayed by the nozzle directly hits the material to evenly humidify the material and fall into the hopper. Since the lower end outlet of the hopper of the conditioner is connected to the negative pressure pipe of the negative pressure lifting system, the upper air supply pipe automatically supplies air under the action of negative pressure, and the material falling into the hopper is discharged under the action of negative pressure and enters the next process.

[0029] Here, the wind shield 8 is fixed on both sides to the fixed plates of the side wall of the conditioning bin, the upper vertical plate of the wind shield is in contact with the top of the conditioning bin, and the lower vertical plate is located outside the blanking end of the vibrating hopper and below the upper air supply duct. The wind shield prevents the wind entering from the upper air supply port from directly blowing onto the material on the vibrating hopper, affecting the uniform and straight forward movement of the material. The upper air supply duct plays the role of air intake, especially under the effect of negative pressure, the wind enters the box from all sides, and under the effect of negative pressure, on the one hand, accelerates the falling speed of the material, on the other hand, enables the falling material to be discharged from the outlet at the lower end of the hopper, and at the same time plays the role of cleaning the conditioning bin and the inner wall of the hopper.

[0030] In this embodiment, the vibrating hopper is arranged as follows. Specifically, two first angle steels 12 are horizontally arranged on the outer side wall of the tempering bin 2 located below the vibrator, and two second angle steels 13 are horizontally arranged on the inner side wall of the tempering bin located below the vibrating hopper. A driving platform 15 is arranged above the first angle steel 12 and the second angle steel 13 through a shock absorbing device 14, and the shock absorbing device 14 is a shock absorbing rubber or a shock absorbing spring. The driving platform 15 is arranged through the side wall of the tempering bin 2, and the vibrator 7 is arranged on the top of the driving platform 15 outside the tempering bin 1, and the vibrating hopper 6 is arranged above the driving platform inside the tempering bin 2 through a support plate 16. Specifically, mounting plates are respectively arranged on the bottom surface of the vibrating hopper and the top of the driving platform, and the two ends of the support plate are fixed on the upper and lower mounting plates to achieve the fixation of the vibrating material belt. The vibrator works, driving the driving platform to vibrate, and then the vibrating hopper arranged on the driving platform vibrates. The material entering the vibrating hopper through the feeding pipe moves forward in a straight line and is evenly distributed under the action of the vibrator. It falls from the drop end of the vibrating hopper to form a uniform waterfall and falls into the conditioning bin for humidification, and further falls into the hopper.

[0031] In order to strengthen the supporting function of the first angle steel and the second angle steel, a first support plate 17 is obliquely arranged between the first angle steel 12 and the outer wall of the quenching and tempering bin, a second support plate 18 is obliquely arranged between the second angle steel 13 and the inner wall of the quenching and tempering bin, and a third angle steel 19 for supporting the second angle steel is arranged along the water pipe direction on the inner wall of the quenching and tempering bin. In addition, a plurality of reinforcing plates 20 are arranged at intervals at the bottom of the vibrating hopper.

[0032] In addition, a material blocking rod 21 is provided inside the drop end of the vibrating hopper 6, and the material blocking rod is used to block the material so that it falls with the vibration of the vibrating hopper, thereby making the swept material fall more evenly.

[0033] In order to ensure the stability of the water pressure in the water pipe, a water tank 22 is provided on the outer side of the conditioning bin 2, and the water tank has a water inlet pipe, and the water inlets of several of the water pipes are connected to the water tank. At the same time, an inspection door 23 is provided on the side of the conditioning bin 2 close to several water pipes, which is convenient for observing the humidification of the materials and for the installation, maintenance and replacement of various components inside the conditioning bin. Furthermore, the upper side panels and top panels of the conditioning bin close to the vibrating hopper can be disassembled, which is convenient for the installation, maintenance and replacement of various components inside the conditioning bin.

[0034] In addition, a pneumatic hammer 24 is provided on the same side of the side wall of the hopper 3 as the vibrator 7, and a material level meter 25 is provided on the side wall of the hopper opposite to the pneumatic hammer 24. The pneumatic hammer plays a vibrating role, causing the attached materials on the inner wall of the hopper to fall. The material level meter is a rotary level meter, which plays the role of transmitting signals of material blockage. It can effectively monitor whether the material in the hopper is blocked and adjust the feeding speed in time. For example, when the speed of the negative pressure lifting system is less than the falling speed of the material, or the negative pressure failure causes the conveying speed to decrease or stop, it will cause the accumulation of materials in the hopper. With the cooperation of automatic control, when the material is blocked in the discharge bin, the rotary level meter in the hopper transmits the information to the host computer, and the host computer stops feeding and stops water inlet to the water pipe until the blocked material is cleaned up and the equipment operates normally.

[0035] In addition, in order to speed up the transfer of materials, the lower outlet of the hopper 3 is provided with a three-way discharge pipe 9 connected thereto, one end of the horizontal pipe of the three-way discharge pipe 9 is a lower air supply port 91, and the other end is a discharge port 92. When the discharge port of the three-way discharge pipe is connected to the negative pressure pipe of the negative pressure lifting system, its lower air supply port is in an open state, which plays the role of air supply and can speed up the flow of materials.

[0036] In the case of no negative pressure feeding system, the material homogenized by the conditioner can be directly put into the silo. Figure 6 As shown, the lower outlet of the hopper 3 is provided with a crushing type discharge valve 26 connected thereto, and the crushing type discharge valve is driven by a motor. The crushing type discharge valve belongs to the prior art product, and is also called a crushing type discharger, a pipeline crusher, a block crushing valve, etc. After the humidified homogenized material is crushed by the crushing type discharge valve, it can directly enter the material bin for temporary storage, or directly enter the next process. The arrangement of the crushing type discharge valve can crush the agglomerated material and play a better protective role in further homogenizing the material.
