Description

Technical Field

[0001] The utility model relates to the technical field of liquid fertilizer production equipment, in particular to an ultra-fine powder spreading device. Background Art

[0002] Liquid fertilizer, referred to as liquid fertilizer, refers to fertilizer without a fixed shape and in a fluid state. In the production process of liquid fertilizer, various raw materials need to be added to water to prepare a solution. There are many kinds of raw materials for liquid fertilizer, such as a liquid potassium dihydrogen phosphate fertilizer disclosed in Chinese patent document with application number CN01132748.0 on May 28, 2003, which is a fertilizer prepared from raw materials with the following weight ratio: phosphoric acid, containing 5.5-10.0 parts of phosphorus pentoxide; potassium hydroxide, containing 16.0-22.0 parts of potassium; agricultural rare earth nitrate, 0.12-0.2 parts; disodium ethylenediaminetetraacetic acid, 0.3- 0.5 parts; carboxymethyl cellulose, 0.8-1.2 parts; a mixture of sodium o-nitrophenolate and sodium 5-nitrophenolate, 0.05-0.1 parts; ferrous sulfate, 0.2-0.4 parts; copper sulfate, 0.08-0.1 parts; zinc sulfate, 0.1-0.15 parts; manganese sulfate, 1.6-2.0 parts; boric acid, 0.15-2.0 parts; ammonium molybdate, 0.16-0.2 parts; the total nitrogen content of the above fertilizers is 2.0-2.5. The above raw materials are stirred in a reaction container to obtain a finished product.

[0003] In the process of liquid fertilizer production, most raw materials can be quickly dissolved in water under stirring, but there are still some raw materials that do not dissolve well due to their own properties and problems with the placement. For example, carboxymethyl cellulose in the aforementioned patent. In the current production process, this raw material is directly added from a bag or barrel to a reaction container, and many small lumps that will not dissolve will appear, which will not only affect the quality of the liquid fertilizer, but also waste the raw materials. In order to solve this problem, the current measure is to manually scatter this raw material in the reaction container.

[0004] The manual hand-spreading method can increase the dissolution amount to a certain extent and reduce the appearance of small lumps, but it is labor-intensive for the operators, and long-term direct contact with these raw materials will also have an impact on health.

[0005] Therefore, there is an urgent need for a device that can evenly spread the powdery raw materials that are easy to clump in water and cannot be dissolved, so as to replace manual hand spreading and improve the quality of liquid fertilizer. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide an ultrafine powder spreading device to address the deficiencies of the prior art. The ultrafine powder raw materials are evenly spread into the solution through multiple discharge ports and vibration, thereby eliminating the phenomenon that the ultrafine powder agglomerates in the solution and cannot be dissolved, thereby improving the quality of liquid fertilizer and reducing the waste of raw materials.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A superfine powder spreading device comprises a silo, a feed pipe, a spreading plate and a micro vibrator. The lower part of the silo is bucket-shaped, and the bottom is connected to a feed pipe. The feed pipe is provided with a plurality of discharge ports. On the feed pipe, a spreading plate is provided below each discharge port and near the discharge port to receive the superfine powder falling from the discharge port. A micro vibrator is fixedly provided on the lower surface of the spreading plate to make the superfine powder on the spreading plate fall evenly from the spreading plate by vibration and spread in a solution.

[0009] Furthermore, a shaftless spring auger is provided in the discharge pipe, and its length is equal to that of the discharge pipe, so that the ultrafine powder can be stably and evenly transported.

[0010] Furthermore, a driving motor connected to a shaftless spring auger is provided at one end of the feed pipe away from the silo.

[0011] Furthermore, the feed tube can be bent into any shape as required.

[0012] Furthermore, the number of the feed pipe is at least one.

[0013] Furthermore, the upper surface of the spreading plate is flat and rough, so that the spreading plate can spread the ultrafine powder in a vibrating and dispersed manner even when it is tilted.

[0014] Furthermore, a protective cover is provided on the micro vibrator below the spreading plate to prevent the micro vibrator from being affected by the ultrafine powder.

[0015] Furthermore, it also comprises a bracket, the silo and the feed pipe are installed on the bracket, and the bracket can be placed on the open mouth of the liquid fertilizer reaction container.

[0016] The utility model discloses an ultrafine powder spreading device. The ultrafine powder raw materials, such as carboxymethyl cellulose, which are easy to form small lumps and particles and difficult to dissolve when directly added into a liquid, are put into a hopper. The driving motor is started to rotate the shaftless spiral auger in the feeding tube, thereby driving the ultrafine powder to enter the feeding tube from the hopper and move at a uniform speed in the feeding tube, and then be continuously discharged from various discharge ports on the feeding tube and fall onto a spreading plate. The micro-vibration electrodes on the lower surface of the spreading plate vibrate all the time, driving the spreading plate to be in a vibrating state. The ultrafine powder that falls onto the spreading plate jumps and disperses under the action of vibration, and falls from the edge of the spreading plate, thereby realizing the non-agglomerated spreading of the ultrafine powder.

[0017] The beneficial effects of the utility model are:

[0018] 1. The utility model provides an ultrafine powder spreading device, wherein a plurality of discharge ports are arranged on a feed pipe and a spreading plate with a vibration function is arranged below the discharge ports, so that the ultrafine powder can enter the liquid without agglomeration under vibration spreading, thereby eliminating the phenomenon of inability to dissolve.

[0019] 2. The ultrafine powder spreading device of the utility model can allow the feeding pipe to cover a larger area by setting the bending shape of the feeding pipe.

[0020] 3. The ultrafine powder spreading device of the utility model can fully dissolve the ultrafine powder, save the amount of ultrafine powder, and reduce the waste of raw materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0028] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0029] In the production process of liquid fertilizer, the reaction vessels used for liquid fertilizer production are usually open, which is convenient for adding various raw materials, observing the state of the liquid fertilizer, and facilitating operation.

[0030] Embodiment 1:

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, a superfine powder spreading device, the upper part of the silo 1 is barrel-shaped, the lower part is cone-shaped, the top is open or an openable hatch is set, so as to facilitate the addition of superfine powder raw materials into the silo 1.

[0032] The silo 1 is connected to a feed pipe 2 at the bottom of the cone, and the feed pipe 2 is spirally unfolded in an Archimedean spiral with the connection part with the silo 1 as the center. A shaftless spiral auger 21 of the same length as the feed pipe 2 is arranged in the feed pipe 2, and a driving motor 24 is arranged at the end of the feed pipe 2 away from the silo 1. The driving motor 24 is connected to the shaftless spiral auger 21 to drive the shaftless spiral auger 21 to rotate, so that the ultrafine powder enters the feed pipe 2 and moves in the feed pipe 2 at a uniform speed.

[0033] A plurality of discharge ports 22 are equidistantly arranged on the discharge pipe 2, and the direction of the discharge ports 22 is not necessarily downward. As long as the ultrafine powder can be discharged from the discharge ports 22, the size of the discharge ports 22 can be smaller than the inner diameter of the discharge pipe 2, which can ensure that ultrafine powder can be discharged from each discharge port 22.

[0034] The feeding tube 2 is provided with a spreading plate 3 below each feeding port 22 near the feeding port 22. The upper surface of the spreading plate 3 is flat and rough, and a micro vibrator 31 is provided on the lower surface, and a protective cover 32 is provided to cover the micro vibrator 31 in the protective cover 32. Specifically, the spreading plate 3 is made of a stainless steel plate with a thickness of 1 mm, and the upper surface is roughened by sandblasting to avoid the smooth state of the mirror surface. The micro vibrator 31 is small in size and has a high vibration frequency, such as a mobile phone vibrator. The ultrafine powder continuously falls from the discharge port 22 onto the spreading plate 3. Under the action of the micro vibrator 31, the spreading plate 3 is always in a vibrating state. After the ultrafine powder falls onto the spreading plate 3, it is vibrated and starts to jump on the spreading plate 3, and gradually disperses and falls from the edge of the spreading plate 3, so that the ultrafine powder does not fall into the liquid in a concentrated manner, that is, the ultrafine powder cannot be concentrated in the liquid, and will not agglomerate, thereby achieving uniform dispersion and dissolution of the ultrafine powder.

[0035] The silo 1 and the discharge pipe 2 can be fixedly mounted on a bracket, and the bracket can be placed on the opening of the reaction container, so that the ultrafine powder can be directly dropped into the solution in the reaction container, thereby realizing the mechanical spreading of the ultrafine powder and improving the spreading efficiency and uniformity.

[0036] Embodiment 2:

[0037] like Figure 4 As shown, the present embodiment is different from the first embodiment in that there are more than one discharge pipes 2, for example, there are five discharge pipes 2, which are radially arranged in a star shape, and the five discharge pipes 2 are all connected to the silo 1 at the lower part of the silo 1.

[0038] In this embodiment, the feed pipe 2 is not only a straight pipe, but can also be bent into other shapes, such as C-shape, S-shape, spiral shape and the like.

[0039] The utility model is a superfine powder spreading device, which can not only spread raw materials such as carboxymethyl cellulose that can be dissolved but not easily dissolved in the process of liquid fertilizer production, but also for insoluble raw materials, such as suspended liquid fertilizer. Some raw materials are suspended in the liquid, such as calcium powder, silicon powder, etc. These raw materials are fine in particles, in the form of superfine powder, with large specific surface area, and the particles are easily adsorbed to each other, and are not easy to disperse in the solution and are easy to agglomerate. After using this device for such insoluble raw materials, the phenomenon of difficulty in dispersion and agglomeration will not occur.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
