Description

Technical Field

[0001] The invention belongs to the technical field of powder storage, and in particular relates to a powder storage device. Background Art

[0002] A powder storage device is a specially designed device for storing and storing powdered raw materials. This device has been widely used and popularized in many fields such as industrial production, construction, and food processing. Especially in the preparation process of soft bread, a variety of different powdered raw materials (such as flour, baking powder, fermentation powder, etc.) are required. The use of a powder storage device can effectively manage and store these powders to ensure that they are in the best condition when used, thereby improving production efficiency and product quality.

[0003] At present, although the existing powder storage devices have achieved sealed storage, in actual use, especially in the process of making soft bread, it is still necessary to take the powder frequently. However, during the process of taking the powder, if the air humidity is high, the powder may become damp, thus affecting its quality and use effect. Summary of the invention

[0004] The object of the present invention is to provide a powder storage device to solve the problems raised in the above background technology.

[0005] In order to achieve the above object, the present invention provides the following technical solution: a powder storage device, comprising a storage tank, a tank cover is installed on the top of the storage tank, and a dehumidification component is arranged inside the storage tank;

[0006] The dehumidification component includes a third rotating shaft arranged inside the storage tank, the third rotating shaft is rotatably connected to the storage tank through the stirring component, the inner wall of the third rotating shaft is evenly provided with first air outlet holes, the bottom end of the third rotating shaft is provided with a first connecting shaft, the bottom end of the first connecting shaft is fixedly connected with an air inlet pipe, a negative pressure fan is provided at one end of the air inlet pipe away from the first connecting shaft, a filter material is provided on one side of the negative pressure fan, the first rotating shaft is fixedly installed on the inner wall of the negative pressure fan, the lower part of the first rotating shaft is connected with a second rotating shaft through a pulley group, the second rotating shaft is installed at both ends of a dual-axis motor, and the dual-axis motor is arranged at the bottom of the storage tank;

[0007] The interior of the can cover is provided with exhaust holes, which are evenly arranged in a circular array, and a first filter screen is installed at one end of each exhaust hole.

[0008] As a further technical solution of the present invention, a buffer plate is fixedly connected to the inside of the exhaust hole. During dehumidification by air blowing, when the gas finally enters the exhaust hole and is discharged, it is first buffered by the buffer plate, thereby reducing the possibility of powder stored in the storage tank being carried out by the gas.

[0009] As a further technical solution of the present invention, a second filter is provided above the buffer plate. The second filter is installed inside the exhaust hole through a shaking assembly to filter the exhausted gas and intercept part of the powder carried away by the gas.

[0010] As a further technical solution of the present invention, the stirring assembly includes a stirring rod fixedly mounted on the outer wall of the third rotating shaft, the stirring rod is evenly arranged, the bottom end of the third rotating shaft is fixedly connected to the first gear, one side of the first gear is meshed with the second gear, a fifth rotating shaft is fixedly mounted inside the second gear, the bottom end of the fifth rotating shaft is fixedly connected to the first bevel gear, one side of the first bevel gear is meshed with the second bevel gear, and the second bevel gear is fixedly mounted on one end of the second rotating shaft.

[0011] As a further technical solution of the present invention, second air outlet holes are evenly opened inside the stirring rod, and the second air outlet holes are connected to the inner cavity of the third rotating shaft. Gas can be discharged from the second air outlet holes, which helps to fully mix the dry gas and the powder, and further improve the dehumidification effect on the powder.

[0012] As a further technical solution of the present invention, a sealing plate is embedded in the interior of the second air outlet, and a connecting rod is fixedly connected to the top end of the sealing plate. A limiting plate is fixedly installed on the top end of the connecting rod, and the limiting plate is slidably installed in the interior of the stirring rod. A spring is arranged between the limiting plate and the stirring rod. When the gas enters the interior of the second air outlet, the air pressure presses the sealing plate downward to discharge the gas. When the sealing plate moves downward, it drives the connecting rod downward, and the movement of the connecting rod drives the movement of the limiting plate. When the limiting plate moves, the spring is deformed by force. When the device is shut down, the elastic potential energy of the spring is released to move the limiting plate up, thereby causing the sealing plate to move up to close the second air outlet, thereby preventing the powder from floating upward into the second air outlet due to the gas flow after shutdown.

[0013] As a further technical solution of the present invention, the shaking assembly includes a pull rope fixedly installed on one side of the second filter screen, and the end of the pull rope away from the second filter screen is installed on the outer wall of the fourth rotating shaft, and the outer wall of the fourth rotating shaft is provided with a second slide groove, and the interior of the second slide groove is slidably connected with a second slider, the second slider is fixedly installed inside the second connecting shaft, the second connecting shaft is slidably installed on the outer wall of the connecting plate, the connecting plate is fixedly installed on the outer wall of the third rotating shaft, and one side of the second connecting shaft is fixedly connected with a first slider, the first slider is slidably installed inside the first slide groove, and the first slide groove is opened inside the tank cover.

[0015] As a further technical solution of the present invention, the fourth rotating shaft is arranged at the top end of the connecting plate, and the fourth rotating shaft is slidably connected to the connecting plate.

[0016] As a further technical solution of the present invention, a sealing gasket is fixedly installed on the outer wall of the third rotating shaft, and the sealing gasket is arranged at the bottom end of the tank cover.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present invention provides a dehumidification component. During the storage of powder materials, when the powder materials need to be dehumidified, the double-axis motor is started to drive the second rotating shafts at both ends to rotate. The rotation of one of the second rotating shafts drives the first rotating shaft to rotate through the belt pulley group. The rotation of the first rotating shaft drives the rotation of the negative pressure fan, so that the interior of the storage tank is negatively pressurized. External gas enters the storage tank and is dehumidified by the filter material. It is guided to the third rotating shaft through the air inlet pipe and finally discharged from the first air outlet into the powder materials in the storage tank, absorbing and taking away the moisture in the powder materials. The gas flows upward to the interior of the exhaust hole and is finally filtered by the first filter screen and discharged outside the device. The gas entering the storage tank is dried by the filter material, and then the dry gas is blown into the interior of the powder materials to take away the moisture in the powder materials, thereby reducing the humidity of the powder materials and improving the storage quality and storage time of the powder materials.

[0019] 2. The present invention arranges a stirring assembly, and a dual-axis motor drives the second rotating shaft to rotate. The rotation of another second rotating shaft drives the rotation of the second bevel gear. The rotation of the second bevel gear drives the rotation of the first bevel gear. The rotation of the first bevel gear drives the rotation of the fifth rotating shaft. The rotation of the fifth rotating shaft drives the rotation of the second gear. The rotation of the second gear drives the rotation of the first gear. The rotation of the first gear drives the rotation of the third rotating shaft. The rotation of the third rotating shaft drives the rotation of the stirring rod, so that the stirring rod stirs the powder inside the storage tank, which helps to fully mix the dry gas with the powder, absorb the moisture in the powder, and thus reduce the humidity of the powder. In addition, since the powder may be stratified during storage due to factors such as gravity, humidity, and temperature, and each time the powder is taken, it is taken from the top, resulting in differences in the composition of the taken powder and the overall powder, thereby affecting the quality and taste of the product. Stirring the powder by the stirring rod can also make the powder composition more uniform and improve the stability of the powder during storage.

[0020] 3. The present invention arranges a shaking assembly. When the third rotating shaft drives the second connecting shaft to rotate through the connecting plate during the rotation process, the rotation of the second connecting shaft drives the first slider to slide back and forth up and down inside the first slide groove. The first slider is guided by the first slide groove to move up and down. The movement of the first slider drives the movement of the second connecting shaft. The movement of the second connecting shaft drives the movement of the second slider, so that the second slider slides in the inner wall of the second slide groove to drive the fourth rotating shaft to rotate. The rotation of the fourth rotating shaft drives the pull rope to pull the second filter screen, so that the second filter screen shakes and shakes off the powder on one side of the second filter screen to prevent blockage and help gas discharge.

DETAILED DESCRIPTION

[0031] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 9 As shown, in an embodiment of the present invention, a powder storage device comprises a storage tank 1, a tank cover 2 is installed on the top of the storage tank 1, and a dehumidification component is arranged inside the storage tank 1;

[0033] The dehumidification component includes a third rotating shaft 9 arranged inside the storage tank 1, the third rotating shaft 9 is rotatably connected to the storage tank 1 through a stirring component, the inner wall of the third rotating shaft 9 is evenly provided with first air outlet holes 10, the bottom end of the third rotating shaft 9 is provided with a first connecting shaft 12, the bottom end of the first connecting shaft 12 is fixedly connected with an air inlet pipe 11, the end of the air inlet pipe 11 away from the first connecting shaft 12 is provided with a negative pressure fan 3, one side of the negative pressure fan 3 is provided with a filter material 8, the inner wall of the negative pressure fan 3 is fixedly installed with a first rotating shaft 4, the lower part of the first rotating shaft 4 is connected with a second rotating shaft 6 through a pulley group 5, the second rotating shaft 6 is installed at both ends of a double-axis motor 7, and the double-axis motor 7 is arranged at the bottom of the storage tank 1;

[0034] The tank cover 2 is provided with exhaust holes 13 in an evenly arranged annular array, and a first filter screen 14 is installed at one end of each exhaust hole 13 .

[0035] The filter material 8 is configured as an activated carbon plate, which is used to remove humidity from the air so that the gas entering the storage tank 1 is dry gas;

[0036] During the storage of powder materials, when it is necessary to dehumidify the powder materials, the dual-axis motor 7 is started to drive the second rotating shafts 6 at both ends to rotate, and the rotation of one of the second rotating shafts 6 drives the first rotating shaft 4 to rotate through the pulley group 5, and the rotation of the first rotating shaft 4 drives the rotation of the negative pressure fan 3, so that the inside of the storage tank 1 is negatively pressurized, and the external gas enters the storage tank 1 and is dehumidified by the filter material 8, and is guided to the third rotating shaft 9 through the air inlet pipe 11, and is finally discharged from the first air outlet 10 to the powder materials in the storage tank 1, absorbing and taking away the moisture in the powder materials, so as to prevent the problem that the powder materials may be dampened and their original physical properties may be changed during the frequent taking of the powder materials, and finally affect their quality and use effect. Finally, the gas flows upward to the inside of the exhaust hole 13, and is discharged outside the device after being filtered by the first filter screen 14. The device dries the gas entering the inside of the storage tank 1 through the filter material 8, and then uses the dry gas to blow into the inside of the powder materials to take away the moisture in the powder materials, thereby reducing the humidity of the powder materials and improving the storage quality of the powder materials.

[0037] The first air outlet 10 is arranged to be inclined downward;

[0038] When the equipment is shut down, the powder inside the storage tank 1 is prevented from entering the first air outlet 10, or the powder that has entered the first air outlet 10 is caused to slide downward.

[0039] like Figure 4 and Figure 5 As shown, a buffer plate 15 is fixedly connected to the interior of the exhaust hole 13 .

[0040] A plurality of buffer plates 15 are disposed inside each exhaust hole 13, and each buffer plate 15 is disposed at an angle;

[0041] When dehumidification is performed by blowing, the gas finally enters the exhaust hole 13 and is first buffered by the buffer plate 15 to reduce the possibility that the powder stored in the storage tank 1 is carried out by the gas.

[0042] like Figure 4 and Figure 5 As shown, a second filter screen 16 is disposed above the buffer plate 15 , and the second filter screen 16 is installed inside the exhaust hole 13 through a shaking assembly.

[0043] The exhaust gas is filtered to intercept some of the powder carried away in the gas.

[0044] like Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, the stirring assembly includes a stirring rod 18 fixedly mounted on the outer wall of the third rotating shaft 9, the stirring rod 18 is evenly arranged, the bottom end of the third rotating shaft 9 is fixedly connected with a first gear 30, one side of the first gear 30 is meshedly connected with a second gear 31, a fifth rotating shaft 32 is fixedly mounted inside the second gear 31, the bottom end of the fifth rotating shaft 32 is fixedly connected with a first bevel gear 33, one side of the first bevel gear 33 is meshedly connected with a second bevel gear 34, and the second bevel gear 34 is fixedly mounted on one end of the second rotating shaft 6.

[0045] The dual-axis motor 7 drives the second rotating shaft 6 to rotate, and the rotation of the other second rotating shaft 6 drives the rotation of the second bevel gear 34, and the rotation of the second bevel gear 34 drives the rotation of the first bevel gear 33, and the rotation of the first bevel gear 33 drives the rotation of the fifth rotating shaft 32, and the rotation of the fifth rotating shaft 32 drives the rotation of the second gear 31, and the rotation of the second gear 31 drives the rotation of the first gear 30, and the rotation of the first gear 30 drives the rotation of the third rotating shaft 9, and the rotation of the third rotating shaft 9 drives the rotation of the stirring rod 18, so that the stirring rod 18 stirs the powder inside the storage tank 1, which helps the dry gas and the powder to be fully mixed, absorbs the moisture in the powder, and thus reduces the humidity of the powder;

[0046] In addition, the powder may be stratified during storage due to factors such as gravity, humidity, and temperature, and each time the powder is taken out, it is taken from the top, resulting in differences in the composition of the taken powder and the overall powder, thereby affecting the quality and taste of the product. Stirring the powder with the stirring rod 18 can also make the powder composition more uniform and improve the stability of the powder during storage.

[0047] The inner wall diameter of the first gear 30 is ten N times the inner wall diameter of the second gear 31, and N is a positive integer;

[0048] It is used to reduce the rotation speed of the third rotating shaft 9, so as to reduce the flying of powder in the storage tank 1 as much as possible.

[0049] like Figure 7 As shown, second air outlet holes 19 are evenly arranged inside the stirring rod 18 .

[0050] The second air outlet 19 is connected to the inner cavity of the third rotating shaft 9, and the gas can be discharged from the second air outlet 19, which helps to fully mix the dry gas with the powder and further improve the dehumidification effect on the powder.

[0051] like Figure 7 and Figure 8 As shown, a sealing plate 36 is embedded inside the second air outlet 19, and a connecting rod 27 is fixedly connected to the top of the sealing plate 36. A limiting plate 28 is fixedly installed on the top of the connecting rod 27. The limiting plate 28 is slidably installed inside the stirring rod 18, and a spring 29 is arranged between the limiting plate 28 and the stirring rod 18.

[0052] The opening diameter of the bottom of the second air outlet hole 19 is larger than the inner wall diameter of the sealing plate 36;

[0053] When the gas enters the second gas outlet 19, the gas pressure pushes the sealing plate 36 downward to discharge the gas;

[0054] When the sealing plate 36 moves downward, it drives the connecting rod 27 to move downward. The movement of the connecting rod 27 drives the movement of the limit plate 28. When the limit plate 28 moves, the spring 29 is deformed by force. When the device is shut down, the elastic potential energy is released by the spring 29 to move the limit plate 28 upward, thereby moving the sealing plate 36 upward to close the second air outlet 19, preventing the powder from floating upward into the second air outlet 19 due to the gas flow after the device is shut down.

[0055] like Figure 4 , 5 and Fig. 9 As shown, the shaking assembly includes a pull rope 35 fixedly mounted on one side of the second filter screen 16, and the end of the pull rope 35 away from the second filter screen 16 is mounted on the outer wall of the fourth rotating shaft 24, and the outer wall of the fourth rotating shaft 24 is provided with a second slide groove 25, and the interior of the second slide groove 25 is slidably connected with a second slider 26, and the second slider 26 is fixedly mounted inside the second connecting shaft 21, and the second connecting shaft 21 is slidably mounted on the outer wall of the connecting plate 20, and the connecting plate 20 is fixedly mounted on the outer wall of the third rotating shaft 9, and one side of the second connecting shaft 21 is fixedly connected with a first slider 22, and the first slider 22 is slidably mounted inside the first slide groove 23, and the first slide groove 23 is opened inside the tank cover 2.

[0056] When the third rotating shaft 9 drives the second connecting shaft 21 to rotate through the connecting plate 20 during the rotation process, the rotation of the second connecting shaft 21 drives the first slider 22 to slide back and forth up and down in the first slide groove 23, and the first slider 22 is guided by the first slide groove 23 to move up and down. The movement of the first slider 22 drives the movement of the second connecting shaft 21, and the movement of the second connecting shaft 21 drives the movement of the second slider 26, so that the second slider 26 slides in the inner wall of the second slide groove 25 to drive the fourth rotating shaft 24 to rotate. The rotation of the fourth rotating shaft 24 drives the pull rope 35 to pull the second filter screen 16, so that the second filter screen 16 shakes, and the powder on one side of the second filter screen 16 is shaken off to prevent blockage and help gas discharge.

[0057] like Figure 4 and Fig. 9 As shown, the connecting plate 20 is slidably connected to the second connecting shaft 21 .

[0058] When the tank cover 2 is removed, the second connecting shaft 21 is slid out from the outer wall of the connecting plate 20 .

[0059] like Figure 4 , Figure 5 and Fig. 9 As shown, the fourth rotating shaft 24 is disposed at the top end of the connecting plate 20 , and the fourth rotating shaft 24 is slidably connected to the connecting plate 20 .

[0060] like Figure 4 , Figure 5 and Fig. 9 As shown, a sealing gasket 17 is fixedly mounted on the outer wall of the third rotating shaft 9 , and the sealing gasket 17 is arranged at the bottom end of the tank cover 2 .

[0061] The third rotating shaft 9 and the tank cover 2 are sealed to prevent powder from entering.

[0062] Working principle and use process: During the storage of powder materials, when the powder materials need to be dehumidified, the dual-shaft motor 7 is started to drive the second rotating shafts 6 at both ends to rotate, and the rotation of one of the second rotating shafts 6 drives the first rotating shaft 4 to rotate through the pulley group 5, and the rotation of the first rotating shaft 4 drives the rotation of the negative pressure fan 3, so that the inside of the storage tank 1 is negatively pressurized, and the external air enters the storage tank 1, is dehumidified by the filter material 8, and is guided to the third rotating shaft 9 through the air inlet pipe 11, and finally discharged from the first air outlet 10 into the powder materials in the storage tank 1;

[0063] A portion of the gas is discharged into the stirring rod 18 and discharged from the second gas outlet 19;

[0064] The rotation of the other second rotating shaft 6 drives the rotation of the second bevel gear 34, the rotation of the second bevel gear 34 drives the rotation of the first bevel gear 33, the rotation of the first bevel gear 33 drives the rotation of the fifth rotating shaft 32, the rotation of the fifth rotating shaft 32 drives the rotation of the second gear 31, the rotation of the second gear 31 drives the rotation of the first gear 30, the rotation of the first gear 30 drives the rotation of the third rotating shaft 9, the rotation of the third rotating shaft 9 drives the rotation of the stirring rod 18, so that the stirring rod 18 stirs the powder inside the storage tank 1;

[0065] The gas flows upward to the inside of the exhaust hole 13, is first buffered by the buffer plate 15, and then filtered by the second filter screen 16;

[0066] The rotation of the third rotating shaft 9 drives the rotation of the second connecting shaft 21 through the connecting plate 20, and the rotation of the second connecting shaft 21 drives the first slider 22 to slide inside the first chute 23. The first slider 22 moves up and down through the guidance of the first chute 23. The movement of the first slider 22 drives the movement of the second connecting shaft 21. The movement of the second connecting shaft 21 drives the movement of the second slider 26, so that the second slider 26 slides in the inner wall of the second chute 25 to drive the fourth rotating shaft 24 to rotate. The rotation of the fourth rotating shaft 24 drives the pull rope 35 to pull the second filter screen 16, so that the second filter screen 16 shakes back and forth, and the powder on one side of the second filter screen 16 is shaken off;

[0067] The gas entering the exhaust hole 13 is finally filtered again by the first filter screen 14 and then discharged out of the device.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
