Description

Technical Field

[0001] This invention relates to the field of flour processing equipment technology, and in particular to a flour drying device. Background Technology

[0002] As an important staple food ingredient in people's lives, flour needs to be stored in a dry and ventilated environment during its processing and production. However, due to long-term storage and changes in the storage environment, the flour at the bottom often becomes damp. Currently, for damp flour, workers often use sieves to separate it, removing larger lumps and manually removing moldy parts. Then, the smaller pieces of flour are crushed and dried for recycling. However, the process is relatively complex and relies on manual operation, which greatly reduces the sieving efficiency and is not conducive to the processing operations of enterprises. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a flour drying device that, by relying on airflow and separation adsorption components, can quickly complete flour screening and recycling without manual operation, greatly improving screening efficiency, simplifying construction process, meeting the needs of large-scale processing, and promoting the normal development of enterprises.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention includes:

[0005] The machine casing has a guide channel on top, two jet sources symmetrically arranged below the guide channel, a feeding assembly located in the middle of the guide channel, a flip-up tray below, and a separation adsorption element located at the discharge end of the tray.

[0006] Preferably, the jet source includes a cylinder and a control motor; the two ends of the cylinder are connected to the housing by rotating shafts, and the cylinder is provided with a plurality of air outlets evenly distributed on it; the control motor is installed at the rear of the housing and connected to the cylinder.

[0007] Preferably, the feeding assembly includes a storage bin and a first hydraulic cylinder; the storage bin is fixed in the middle area of ​​the guide channel, and a feed pipe communicating with the outside is provided on one side; the first hydraulic cylinder is fixed on the top of the machine housing, and a lifting component is provided on the push rod of the first hydraulic cylinder.

[0008] Preferably, the bottom of the lifting member has an arc-shaped surface.

[0009] Preferably, a second hydraulic cylinder connected to the chassis is provided below the tray, the tray has a hollow structure inside, the surface is made of flexible material, and the inside is filled with a medium.

[0010] Preferably, the separation and adsorption component includes a base plate, an upper chamber, and a pressure plate; the base plate is inclined and fixed on the chassis and located below the discharge end on the right side of the tray, and multiple air jet holes are evenly arranged on the base plate; the upper chamber is slidably connected to the chassis and is arranged parallel to the base plate, and a third hydraulic cylinder is provided above the upper chamber; the upper surface of the pressure plate is connected to the third hydraulic cylinder and forms an exhaust chamber with the upper chamber, the exhaust chamber is connected to the powder outlet of the guide channel, and multiple suction holes and a flexible tentacles are evenly arranged on the pressure plate.

[0011] Preferably, the base plate is provided with uniformly distributed tentacle structures.

[0012] Preferably, the top wall of the upper box is provided with a magnetic suction plate, and the upper surface of the pressure plate is provided with multiple impact members, which are attracted to the magnetic suction plate after contact.

[0013] Preferably, the impact component includes an elastic rope and a sphere; one end of the elastic rope is connected to the pressure plate, and the other end is fixedly connected to the sphere.

[0014] Preferably, the powder outlet of the guide channel is equipped with a circulating drying component.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. By generating an upward thrust through airflow, the flour and powder lumps can be separated in one go. After falling, the small powder lumps are crushed by the separation and adsorption components, and the harder powder lumps are removed, thus avoiding contamination of the original flour by the unusable parts. The structure is reasonable and reliable.

[0017] 2. The overall screening efficiency is greatly improved by the cooperation between the jet source and the separation adsorption component. The feeding component automatically feeds the material without the need for manual intervention, reducing labor intensity and making it easy to promote in the factory area.

[0018] 3. During the kneading process, the separation and adsorption components generate negative pressure adsorption capacity. Combined with the air blowing on the bottom plate, the crushed flour can be recycled again and connected to the guide channel to achieve centralized storage and utilization. The layout is reasonable.

[0019] 4. The feeding component slowly pushes the incoming flour out of the storage box by lifting it. With the help of the air jet source, it can effectively separate the flour and lumps. Compared with the traditional vibrating screen, it avoids the damage of moldy flour lumps, which affects the overall recycling quality.

[0020] 5. The tray surface forms a flexible support, which can greatly reduce the damage when powder blocks fall, thus enabling re-kneading as needed, which is safe and reliable;

[0021] 6. The circulating drying unit dries the recovered flour and automatically collects and utilizes it, saving labor and matching the screening structure well to form a complete processing production line. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0035] Specific implementation method one: Combining Figure 1-11 As shown, a flour drying device includes: a housing 1, a guide channel 101 above the housing 1, two air jets 2 symmetrically arranged below the guide channel 101, a feeding assembly 3 located in the middle of the guide channel 101, a flip-up tray 4 located below, and a separation adsorption element 5 located at the discharge end of the tray 4.

[0036] Preferred embodiments, in combination Figure 1-3 As shown, the jet source 2 includes a cylinder 201 and a control motor 202. The two ends of the cylinder 201 are connected to the housing 1 by rotating shafts. The cylinder 201 is uniformly provided with multiple rectangular strip-shaped air outlets 203, and the cylinder 201 is connected to an external air supply device to generate high-pressure jets. The control motor 202 is installed at the rear of the housing 1 and connected to the cylinder 201. It is used to control the tilt angle of the cylinder 201, thereby changing the position and height of the cross airflow between the two cylinders 201 to meet the flour separation under different conditions. When the flour is less moist, the position of the cross airflow can be increased to quickly push the flour to separate. When the flour is more moist, the position of the cross airflow can be lowered so that the flour is first subjected to the thrust of the airflow during the descent and then further separated after reaching the turbulent area.

[0037] Preferred embodiments, in combination Figure 4 and Figure 5 As shown, the feeding assembly 3 includes a storage bin 301 and a first hydraulic cylinder 302. The storage bin 301 is fixed in the middle area of ​​the guide channel 101, and a feed pipe 303 communicating with the outside is provided on one side. The first hydraulic cylinder 302 is fixed on the top of the machine box 1. A lifting member 304 is provided on the push rod of the first hydraulic cylinder 302. The lifting member 304 is rectangular and has a certain height. When feeding, the first hydraulic cylinder 302 pushes the upper surface of the lifting member 304 close to the lower surface of the storage bin 301, thereby reserving the volume space for the flour to slide out of the feed pipe 303. When feeding is required, the first hydraulic cylinder 302 pulls upward to drive the internal flour to fall from the top of the storage bin 301, thereby realizing feeding.

[0038] Preferred embodiments, in combination Figure 4 As shown, the bottom of the lifting component 304 has an arc-shaped surface, which reduces interference with the airflow below when the guide channel 101 is cleared.

[0039] Preferred embodiments, in combination Figure 1 and Figure 5 As shown, a second hydraulic cylinder 401 connected to the housing 1 is provided below the tray 4 to control the tilt angle of the tray 4. At the same time, the right side of the tray 4 is connected to the housing 1 by a rotating shaft. The inside of the tray 4 is a hollow structure and is filled with gas or liquid. The surface is made of rubber material, which, together with the medium, forms a flexible support to reduce the possibility of damage when the powder blocks fall.

[0040] In a preferred embodiment, the surface of the tray 4 is higher on the left and lower on the right, and the surface has a certain curvature, which facilitates unloading by tilting to the right.

[0041] Preferred embodiments, in combination Figure 5-9 As shown, the separation and adsorption component 5 includes a base plate 6, an upper chamber 7, and a pressure plate 8. The base plate 6 is inclined and fixed on the casing 1 to facilitate the displacement of powder blocks. The base plate 6 is located below the discharge end on the right side of the tray 4, forming a support channel with the tray 4. Multiple air jet holes 601 are evenly arranged on the base plate 6, communicating with the air chamber below. The air chamber is connected to an external air supply device via a pipeline, thus generating either a continuous upward airflow or intermittent airflow, selectable as needed. The upper chamber 7 has slide rails at the front and rear, and corresponding slide bars are provided on the casing 1. The slide bars and slide rails cooperate to form a sliding connection with the casing 1. A fourth hydraulic cylinder is located on the right side of the upper chamber 7 to control its left and right sliding. The upper chamber 7 is parallel to the base plate 6 with a certain distance between them. A third hydraulic cylinder 701 is located above the upper chamber 7 to control the height adjustment of the pressure plate 8 inside the upper chamber 7. The upper surface of plate 8 is connected to the third hydraulic cylinder 701 and forms an exhaust chamber 801 with the upper box 7. The exhaust chamber 801 is connected to the powder outlet of the guide channel 101 through a pipeline. Multiple suction holes 802 and flexible tentacle structures 803 are evenly provided on the pressure plate 8. After the flour reaches the bottom plate 6, the third hydraulic cylinder 701 pushes the pressure plate 8 to move, so that the tentacle structure 803 contacts the flour block. During the pressing process, the flour block that is not severely damp can be crushed, while the moldy part will not be damaged. As the fourth hydraulic cylinder drives the upper box 7 to move from left to right, the kneading action of the flour block is completed, further crushing the block. The above action is repeated to complete the secondary screening operation, and the unusable flour block can be continuously pushed to the right to fall. During the kneading process, the air jet hole 601 on the bottom plate 6 generates an upward airflow, which lifts the flour. With the help of the suction hole 802 above, the flour is extracted and collected. The structure is ingenious.

[0042] In a preferred embodiment, in order to increase the negative pressure suction of the air intake 802, a fan can be installed on the connecting pipe between the exhaust chamber 801 and the guide channel 101 to increase the suction.

[0043] Preferred embodiments, in combination Figure 6 As shown, the base plate 6 is provided with evenly distributed tentacle structures 803. The tentacle structures 803 are made of rubber and are cylindrical in shape. They can also be designed with pointed ends. By arranging them on the base plate 6, they can support the powder blocks, making it easier to lift the flour. In addition, in conjunction with the tentacle structures on the pressure plate 8, they can better form a kneading action and prevent the moldy powder blocks from being damaged.

[0044] Preferred embodiments, in combination Figure 8 and Figure 9 As shown, a magnetic suction plate 702 is provided on the top wall of the upper box 7, and multiple impact members 9 are provided on the upper surface of the pressure plate 8. After the impact members 9 come into contact with the magnetic suction plate 702, they are attracted and, after the pressure plate 8 descends to a specified height, they overcome the magnetic attraction and impact the upper part of the pressure plate 8 through the impact members 9, thereby preventing too much flour from settling on the upper surface of the pressure plate 8. In addition, the vibration force can also clean the flour at the air suction hole 802 at the same time.

[0045] Preferred embodiments, in combination Figure 9 As shown, the impact component 9 includes an elastic rope 901 and a sphere 902; one end of the elastic rope 901 is connected to the pressure plate 8, and the other end is fixedly connected to the sphere 902. The elasticity of the elastic rope 901 is released to form an impact on the pressure plate 8. The sphere is made of metal and can be attracted to the magnetic suction plate 702.

[0046] Preferred embodiments, in combination Figure 9 As shown, the cross-sectional shape of the air intake 802 is trapezoidal, with a small gap at the top and a large gap at the bottom, which can better collect flour.

[0047] Preferred embodiments, in combination Figure 10 As shown, the powder outlet of the guide channel 101 is equipped with a circulating drying component 10, which can realize the drying operation of the collected flour.

[0048] Preferred embodiments, in combination Figure 11As shown, the circulating drying component 10 includes a collection box and a turntable 11. The collection box is divided into upper and lower spaces. The upper space is a cylindrical upper space 13, and the lower space is a rectangular lower space 15. A power motor is installed at the top of the upper space 13, which is connected to the turntable 11 inside the upper space 13 to drive the rotation of the turntable 11. The upper space 13 also has a hole for connecting to a pipeline, allowing the collected flour to enter smoothly. A semi-partition is provided at the connection between the upper space 13 and the lower space 15. 14. The bottom of the filter cylinder 12 is blocked. The turntable 11 has three through holes, and a filter cylinder 12 is fixed at each through hole. The surface of the filter cylinder 12 is distributed with small holes, and a filter cloth can also be laid to achieve the filtration and collection of flour. The lower space 15 has an inclined drying plate 16. Heating wires are distributed below the drying plate 16 to achieve the drying and reuse of flour. After working for a period of time, the turntable 11 is rotated at a certain angle by the power motor, which can adjust the filter cylinder 12 to meet the needs of long-term collection operation.
