Description

Technical Field

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

[0002] When storing powder (for example, salt, sand and other granular materials), an opening is usually set at the top of the storage bin to load the materials. Figure 1 , when loading, a stacking angle is usually formed in the storage bin, resulting in the inability to fully utilize the storage bin volume; for example: a cylindrical storage bin with a diameter of 2m and a height of 1m has a volume of about 314L. When loading from the center hole of the top surface, when the powder stacking angle is 45 degrees, the material level has reached the top loading hole of the storage bin when about 157L of powder is loaded. If no manual intervention (leveling) is performed, loading will not be possible, and the volume utilization rate (material volume / container volume) is only about 50%. In addition, even if manual intervention (leveling) is performed, the volume utilization rate is limited due to the ratio of the opening size of the loading hole to the size of the storage bin, the influence of leveling tools and other factors, and the improvement of the volume utilization rate is limited.

[0003] To solve the above-mentioned problem of storage silo volume utilization, the storage silos commonly used in the prior art are usually square or cylindrical, and the height is significantly higher than the width / diameter. However, if the height of the silo is high, the space requirement will be high. Some scenes cannot arrange storage silos that are too high, and storage silos that are too high will also cause inconvenience in loading (for example, climbing operations are required).

[0004] In addition, in order to solve the problem of the shape of the powder accumulation surface, the following solutions are often used in the prior art:

[0005] (1) Install a vibration device on the side wall of the storage bin to promote the flow of powder and reduce the accumulation angle, similar to the powder arch breaking. However, this method can only slightly improve the situation and cannot achieve the ideal effect; and vibration will also lead to problems such as shortened fatigue life of other parts, reduced reliability, and loose fasteners.

[0006] (2) A stirring device is installed above the storage bin, and the powder is pushed to move around by blades. However, the blades are required to cover the entire plane (horizontal plane projection of the storage bin) as much as possible. The blades are large in size, inconvenient to install, and a large opening / cover is required. In addition, the blade structure strength is high and the power source torque is high, which is not simple enough.

[0007] (3) A push plate or push rod is set in the storage bin to push the powder above its lower edge, similar to a manual scraper. However, it requires an additional mechanism such as a guide rail as a power source, and the length of the plate / rod must be equal to the paved area, which occupies a large space and has a complex structure.

[0051] In order to make the technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0052] like Figures 2 to 11 As shown, the utility model provides a powder spraying device, comprising: a sprayer 1;

[0053] The sprayer 1 comprises: a driving device 11, a rotating disk 12 and a mounting member 13;

[0054] The rotating disk 12 is fixedly connected to the output end of the driving device 11;

[0055] The rotating disk 12 includes a bottom plate 121 and at least one blade 122; the blade 122 is arranged on the upper surface of the bottom plate 121;

[0056] The mounting member 13 is connected to the driving device 11;

[0057] The powder spraying device further comprises a baffle, which is connected at a preset height directly above the sprayer, and a through hole is arranged on the baffle at a position opposite to the rotating disk of the sprayer.

[0058] In the technical solution of the utility model, the above-mentioned sprayer 1 can be applied to a variety of external devices with a feeding port. When the above-mentioned sprayer 1 is needed, the above-mentioned sprayer 1 can be first installed on the external device (for example, an external storage device) through its mounting member 13, and the sprayer 1 is located below the feeding port of the external device. When feeding into the external material storage device, the powder falls from the feeding port of the external material storage device and falls onto the turntable 12 of the sprayer 1. Since the turntable 12 is fixedly connected to the output end of the driving device 11, the turntable 12 will rotate at a high speed under the action of the driving device 11, so that the powder falling on the turntable 12 is thrown to the outside of the turntable under the action of friction and the thrust of the turntable blades, so that the powder can be sprayed to various places in the external material storage device, gradually forming a "V"-shaped accumulation surface; at the same time, part of the powder that falls to the sprayer 1 and splashes upward is blocked by the baffle plate and falls back into the material storage device, so that the powder is prevented from splashing outside the material storage device; with the continuous increase of the powder in the external material storage device, the powder can even submerge the sprayer. At this time, the sprayer can still perform the spraying work, stirring the powder in the storage bin, so that the powder evenly fills the entire external material storage device, so that the volume utilization rate of the external material storage device can be close to 100%, which significantly improves the volume utilization rate of the external material storage device.

[0059] In the technical solution of the utility model, a variety of implementation methods can be used to implement the above-mentioned powder spraying device. The technical solution of the utility model will be described in detail below by taking several implementation methods as examples.

[0060] For example, preferably, in a specific embodiment of the present invention, Figure 3 As shown, the mounting member 13 may include a mounting seat 132 and a connecting member 133; wherein the bottom end of the connecting member 133 is connected to the mounting seat 132 and is located at the edge of the mounting seat 132;

[0061] The turntable 12 is placed on the upper surface of the mounting seat 132 and is located in the middle of the mounting seat 132 ; the driving device 11 is fixedly connected to the mounting seat 132 , and the output end of the driving device 11 passes through a through hole reserved on the mounting seat 132 and is fixedly connected to the turntable 12 .

[0062] For another example, preferably, in a specific embodiment of the present utility model, Figure 4 As shown, the blade 122 may be provided in plurality, and the plurality of blades 122 are arranged at intervals on the upper surface of the chassis 121 , and each blade 122 is respectively arranged along each radial direction of the chassis 121 .

[0063] By setting the turntable to a structure of a chassis plus multiple blades, when powder falls on the turntable, the blades can be used to push the powder to the outside of the turntable, ensuring that most of the powder is thrown to the surroundings of the external storage device, preventing a large amount of powder from accumulating in the middle of the external storage device.

[0064] In addition, as an example, in a preferred specific embodiment of the present invention, the powder spraying device may also include a baffle (not shown in the figure), which is connected at a preset height directly above the sprayer 1, and a through hole is provided on the baffle at a position opposite to the turntable 12 of the sprayer.

[0065] Preferably, as an example, for different powders, turntable blades made of different materials can be used. For example, in order to avoid damaging the powder structure, the blades 122 can be set to be made of soft materials such as rubber.

[0066] In addition, in the technical solution of the present utility model, a variety of implementation methods can be used to implement the above-mentioned turntable.

[0067] For example, as an example, in a preferred specific embodiment of the present invention, as Figure 4 As shown, the blades 122 on the turntable 12 may be a rectangular rib structure.

[0068] For another example, as an example, in a preferred specific embodiment of the present utility model, as Figure 5 As shown, the blades 122 on the rotating disk 12 may also be a trapezoidal rib structure with a high middle portion and a low outer portion, so that the powder can be more easily dropped from the rotating disk.

[0069] In addition, preferably, as an example, in a preferred specific embodiment of the present utility model, as Figure 6 As shown, the bottom plate 121 may be a symmetrical structure with a middle portion convex upward, so that the powder can be more easily dropped from the rotating plate.

[0070] In addition, preferably, as an example, in another preferred specific embodiment of the present invention, the chassis 121 may also be a symmetrical structure with a downward depression in the middle.

[0071] In addition, preferably, as an example, in a preferred specific embodiment of the present utility model, the chassis 121 can be a symmetrical structure with through holes. The chassis can be set as a hollow structure with through holes, so that the powder is more convenient to fall and the weight of the turntable itself can be reduced.

[0072] In addition, preferably, as an example, in a preferred specific embodiment of the present utility model, the driving device 11 can be a motor with a preset power. A motor with a suitable power and model can be selected according to the external equipment installed in the sprayer.

[0073] In addition, in the technical solution of the present utility model, the sprayer 1 can be arranged on a variety of external devices, and the external devices can be a variety of different external material storages. The technical solution of the present utility model will be described in detail below by taking several implementation modes as examples.

[0074] Embodiment 1

[0075] For example, preferably, in a specific embodiment of the present invention, Figure 7 and Figure 8 As shown, the powder spraying device may further include a solution preparation device 2; the solution preparation device 2 may include a storage bin 21 and a preparation bin 22;

[0076] The storage bin 21 is arranged on the top of the preparation bin 22, and a through hole 26 connected to the preparation bin 22 is arranged at the bottom of the storage bin 21, and a blocking device is arranged at the through hole 26;

[0077] The top plate of the storage bin serves as a baffle, and a feeding port is arranged on the top plate of the storage bin; the sprayer 1 is fixed in the storage bin 21 through its mounting member 13 and is located directly below the feeding port.

[0078] In the technical scheme of the utility model, the solute powder (for example, salt) required for preparing the solution can be added to the storage bin from the charging port at the top of the storage bin 21. When the solute powder enters the storage bin from the charging port, it will fall on the turntable of the sprayer located just below the charging port. The turntable rotates under the action of the driving device, so that the solute powder can be sprayed to various positions in the storage bin, thereby preventing the solute powder from accumulating only in the middle of the storage bin, and improving the volume utilization rate of the storage bin. When it is necessary to prepare the solution, the blocking device provided at the through hole 26 can be opened, so that the solute powder can enter the preparation bin 22 from the through hole 26. When the solute powder is sufficient, the blocking device is closed. In addition, a solvent can be added to the preparation bin through a corresponding pipeline pre-connected on the preparation bin (for example, pure water can be added to the preparation bin through a pure water pipeline connected on the preparation bin), so that a corresponding solution can be prepared.

[0079] Preferably, as an example, in a specific embodiment of the present utility model, Figure 8 As shown, the blocking device may include an electric push rod 24 and a blocking plug 25;

[0080] The electric push rod 24 is fixed to the bottom of the sprayer 1;

[0081] The sealing plug 25 is fixed at the free end of the electric push rod 24 , and the sealing plug 25 is located right above the through hole 26 .

[0082] In the technical solution of the utility model, the electric push rod may include a sleeve and a telescopic rod, the telescopic rod is slidably arranged in the sleeve, and the telescopic rod can move in the sleeve under the drive of the driving motor. When there is no need to prepare the solution, the telescopic rod of the electric push rod extends outward, so that the sealing plug 25 at its free end seals the through hole 26; when it is necessary to add material to the preparation bin, the electric push rod can be started to retract its free end, and at the same time drive the sealing plug 25 to move upward a preset distance and leave the through hole 26. After the through hole is opened, the solute powder enters the preparation bin from the through hole 26, thereby completing the preparation of the solution.

[0083] According to the above content, the utility model can realize the automation of preparing solution by arranging the blocking device at the bottom of the sprayer and using the electric push rod to realize the opening and closing control of the through hole instead of manual opening and closing of the through hole.

[0084] In addition, preferably, as an example, in a specific embodiment of the present utility model, Figure 7 and Figure 8 As shown, a plurality of (for example, four) obliquely placed baffles 211 may be provided in the storage bin 21, the top end of each baffle is fixed on the inner wall of the storage bin 21, the bottom end of each baffle is fixed around the through hole 26, and adjacent baffles are spliced ​​and fixed to each other.

[0085] In the technical solution of the utility model, by adding an inclined baffle in the storage bin, the solute powder can slide down along the baffle to the top of the through hole, preventing the powder from remaining at the bottom of the storage bin and not falling into the preparation bin from the through hole. In addition, the space isolated between the baffle and the storage bin can be used to place mechanical or electrical components required for preparing the solution (for example, a pump body or pipeline for adding solvents, etc.), so that the space inside the solution preparation device can be fully utilized to ensure its external aesthetics.

[0086] In addition, as an example, in a preferred specific embodiment of the present utility model, as Figure 7 As shown, the feeding port of the solution preparation device can also be covered with a cover 28, and the cover 28 can be connected to the feeding port by threads. After the feeding is completed, the cover can be screwed on to prevent impurities from entering the storage bin.

[0087] Embodiment 2

[0088] For another example, preferably, in another specific embodiment of the present invention, Fig. 9 As shown, the powder spraying device may also include a sand box 3, and the sand box 3 may include: a box body 31, a box cover 32 and a box cover opening and closing device 33;

[0089] The top plate of the box body serves as a baffle, and a sand inlet hole is provided on the top plate. The sprayer 1 is fixed in the box body 31 through its mounting member 13 and is located directly below the sand inlet hole.

[0090] A box cover 32 matching the sand inlet hole is arranged just above the sand inlet hole, and the box cover 32 is connected to the box body 31 through a box cover opening and closing device 33 .

[0091] In the technical solution of the utility model, when it is necessary to add sand into the sand box 3, the box cover 32 can be opened by using the box cover opening and closing device 33, and sand can be added into the box through the sand inlet hole. The sand falls from the sand inlet hole onto the turntable 12 of the sprayer located just below the sand inlet hole. The turntable 12 rotates under the action of its driving device 11, so that the turntable can be used to spray the sand to various positions in the box, preventing the sand from accumulating only in the middle position of the box, thereby improving the volume utilization rate of the box loaded with sand.

[0092] In the technical solution of the utility model, the sand box 3 can be a vehicle-mounted sand box on a train for spraying sand between the wheels and the tracks to increase the friction of the wheels. For example, the vehicle-mounted sand box is installed on the train and is located near the wheels. A sand outlet pipe can be connected to the bottom of the sand box. During the running of the train, sand flows out of the sand outlet pipe and is sprayed between the wheels and the tracks, thereby increasing the friction between the wheels and the tracks and ensuring driving safety. When the train stops at a station, sand needs to be added to the sand box regularly. When adding sand, the sprayer provided in the present application is used. It is small and does not take up space, and the space in the sand box can be fully utilized to allow more sand to be loaded into the sand box, thereby extending the sand adding cycle and reducing the sand adding workload.

[0093] In addition, preferably, in another specific embodiment of the present invention, as Fig. 9 As shown, a movable feeding device 34 may be further provided above the sand box 3, and a splash-proof portion 341 for covering the sand inlet hole is provided at the discharge port of the movable feeding device 34.

[0094] Preferably, as an example, the splash guard 341 may be in an umbrella shape or a straight plate shape.

[0095] In the technical solution of the utility model, a movable feeding device 34 can be used to feed material into the sand box 3. When feeding, the discharge port of the movable feeding device 34 is located directly above the sand inlet hole, and the splash-proof portion 341 covers the sand inlet hole, thereby preventing the sand from splashing to the outside of the sand box through the sand inlet hole during the process of entering the sand box from the movable feeding device, thereby preventing the waste of sand and ensuring the hygiene near the sand box.

[0096] For another example, preferably, in a specific embodiment of the present utility model, Fig. 9 As shown, the box cover opening and closing device 33 may include: a bracket 336, an electric push rod 337 and an electric push rod base 339;

[0097] The bracket 336 is fixed on the box body 31, and the top of the bracket 336 extends upward to a preset height;

[0098] The bottom of the electric push rod 337 is fixed on the electric push rod base 339, and the electric push rod base 339 is hinged to the top of the bracket 336;

[0099] The output end of the electric push rod 337 is hinged to the middle of the box cover 32; the side of the box cover 32 close to the electric push rod is rotatably connected to the box body 31 through a rotating shaft 322.

[0100] In the technical solution of the utility model, the electric push rod 337 may include a telescopic rod and a sleeve, wherein one end of the telescopic rod is sleeved in the sleeve, and the telescopic rod can telescopically move in the sleeve under the action of the motor, and the other end of the telescopic rod (i.e., the output end) is hinged with the middle part of the box cover 32; the bottom of the sleeve is fixed on the electric push rod base 339. When it is necessary to add sand to the sand box, the telescopic rod of the electric push rod 337 is retracted into the sleeve, and the box cover 32 is pulled up and turned (that is, the box cover 32 is rotated upward around the rotating shaft 322), so that the box cover is opened. When it is necessary to cover the box cover, it is only necessary to extend the telescopic rod of the electric push rod outward to push the box cover to turn downward. At the same time, since the electric push rod base 339 and the top of the bracket 336, and the output end of the electric push rod 337 and the box cover 32 are all hinged, the electric push rod base and the bracket, and the output end of the electric push rod and the box cover can be adaptively rotated with the turning of the box cover, so that the box cover can be closed in place without being stuck.

[0101] Embodiment 3

[0102] In addition, as an example, in a preferred specific embodiment of the present invention, Fig.10 As shown, the powder spraying device may also include a storage bin 4, and the storage bin 4 may include: a bin body 41;

[0103] The top plate of the silo body is used as a baffle, and a feed port is provided on the top plate, and a feed pipe 44 for feeding materials into the silo body is connected to the feed port;

[0104] The sprayer 1 is fixed to the top of the bin body 1 through its mounting member 13 and is located directly below the feed port.

[0105] In addition, as an example, in a preferred specific embodiment of the present utility model, as Fig.11 As shown, a storage bin equipped with a plurality of the above-mentioned sprayers 1 is also provided, comprising: a bin body 41, a primary sprayer 1-1 and a plurality of secondary sprayers 1-2;

[0106] The primary sprayer 1-1 is fixed to the top of the bin body 1 through its mounting member 13 and is located directly below the feed port;

[0107] The multiple secondary sprayers 1-2 are arranged around the primary sprayer 1-1 and are fixed to the top of the warehouse body 41 through the suspension rods 43 respectively, and the height of the secondary sprayer 1-2 is lower than that of the primary sprayer 1-1.

[0108] In the prior art, various materials are usually stored in a storage bin (for example, grain can be stored in the storage bin). Taking grain storage as an example, grain enters the storage bin through a feed pipe 44, and the grain will be piled up in the middle of the storage bin. Since the space in the storage bin is too large, the space around the storage bin cannot be fully utilized. Usually, a staff member enters the storage bin from a bin door 42 reserved at the bottom of the storage bin, and spreads the grain in the storage bin so that the grain is evenly distributed in the storage bin. This not only has a large workload, but also has low safety. When there is enough grain in the storage bin, it is not easy for the staff member to enter the storage bin, and the entire storage bin cannot be filled with grain, resulting in a waste of space in the storage bin. In the technical solution of the utility model, by setting a plurality of sprayers, the grain entering the storage bin can be sprayed to various positions in the storage bin. Since the space in the storage bin is large, a double sprayer is set. The grain first falls from the feed port onto the turntable of the first-level sprayer 1-1. The first-level sprayer 1-1 sprays the grain to various places around it. Since the second-level sprayer is located below the first-level sprayer, part of the grain can further fall onto each second-level sprayer 1-2, so that the grain is sprayed to a farther position again. Therefore, by setting multiple sprayers, the grain can be sprayed to various positions in the storage bin, realizing full utilization of the space in the storage bin, and no longer needing to use manual spreading, which greatly saves labor and improves safety.

[0109] Of course, according to different application scenarios of the sprayer, its overall size, the power of the driving device 11, the strength of the turntable 12 and other parameters can be appropriately adjusted and designed.

[0110] In summary, in the technical solution of the utility model, by arranging a rotating disk on the sprayer, installing the sprayer on the external storage device, and making the sprayer located below the feeding port of the external storage device, the volume utilization rate of the storage device can be close to 100%, which significantly improves the volume utilization rate of the storage device. Furthermore, the sprayer has a wide range of uses and can be applied to storage devices in various fields, which can save labor and cost.

[0111] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
