Description

Technical Field

[0001] The utility model relates to the technical field of pollen processing, in particular to pollen screening equipment. Background Art

[0002] Pollen refers to the product collected from the flowers of plants and can be used in many fields such as food, medicine, health products, cosmetics, etc.

[0003] Pollen may be mixed with impurities such as stamens, petals, flower and grass residues, and insects. Therefore, it is necessary to separate larger impurities from the pollen through screening to improve the purity and quality of the pollen, ensure a more uniform particle size distribution in the pollen, reduce the difference between different batches, and improve product consistency. If graded screening is used, the pollen can also be classified according to particle size to obtain pollen with a specific particle size range that meets the requirements. For example, in the food industry, screening can be used to obtain a consistent particle size distribution to ensure product quality and taste.

[0004] The commonly used pollen multi-stage screening equipment uses multiple overlapping sieves with gradually changing mesh sizes to screen the pollen in multiple stages. While removing impurities, it can also screen the pollen into multiple grades according to the particle size. However, pollen is generally moist and often prone to agglomeration. Agglomerated pollen blocks need a long time to be broken up and sieved off on the sieve, which reduces the screening efficiency of the pollen.

[0005] To this end, the present application specifically proposes a pollen screening device to solve the above technical problems. Utility Model Content

[0006] The main purpose of the utility model is to solve the above-mentioned shortcomings and provide a pollen screening device, which can break up the agglomerated pollen blocks in the pollen and then screen them, thereby improving the overall screening efficiency.

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

[0008] A pollen screening device comprises: a vibrating screen, the vibrating screen being stacked with a plurality of sieve plates with different mesh sizes; a mounting shell, erected just above a feeding port of the vibrating screen, a feeding port being arranged at the top of the mounting shell, and a conical discharge port being arranged at the bottom of the mounting shell; a coarse sieve plate, fixedly arranged in the mounting shell; and a grinding and scattering assembly, rotatably arranged on the top surface of the coarse sieve plate, for grinding and scattering block pollen falling on the coarse sieve plate.

[0009] Furthermore, the grinding assembly includes a rotating shaft rotatably arranged on the coarse screen plate, a plurality of protective shells evenly arranged around the coarse screen plate, a grinding roller rotatably arranged in the protective shell, and a driving motor fixedly arranged on the top surface of the mounting shell and transmission-connected to one end of the rotating shaft extending out of the mounting shell.

[0010] Furthermore, the rolling roller is an electric heating roller.

[0011] Furthermore, the top of the protective shell is configured as a curved surface.

[0012] Further, the rolling roller does not contact the coarse screen disc.

[0013] Furthermore, the conical discharge port does not contact the feeding port of the vibrating screen.

[0014] Furthermore, the coarse screen plate includes a mounting frame fixedly arranged in the mounting shell and a screen arranged on the mounting frame, the mounting frame is composed of an inner ring, an outer ring and a plurality of ribs evenly arranged between the inner and outer rings, and the screen is arranged between adjacent ribs.

[0015] Furthermore, it also includes a hot air blower fixedly arranged on the installation shell, and the air outlet of the hot air blower is connected to the inner cavity of the installation shell through a connecting pipe.

[0016] The beneficial effects of the utility model are embodied in:

[0017] 1. The utility model sets a mounting shell at the feeding port of the vibrating screen, and sets a coarse screen plate and a grinding component in the mounting shell. Before the formal screening of pollen begins, the blocky pollen is first screened out by the coarse screen plate, and then the blocky pollen is ground by the grinding component to reduce the volume of the agglomerates, so that the subsequent screening process can be more efficient.

[0018] 2. The utility model sets the crushing roller in the crushing assembly as an electric heating roller, and introduces hot air into the installation shell by setting a hot air blower and a connecting pipe, so as to heat the block pollen during the crushing process to evaporate excess moisture, thereby achieving a better crushing effect.

DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] like Figure 1-5 As shown, the utility model provides a pollen screening device, comprising:

[0028] A vibrating screen 1, wherein the vibrating screen 1 is stacked and provided with a plurality of sieve plates with different mesh sizes;

[0029] The installation shell 2 is erected just above the feeding port of the vibrating screen 1. The top of the installation shell 2 is provided with a feeding port 3, and the bottom of the installation shell 2 is provided with a conical discharge port 4;

[0030] A coarse screen plate 5 is fixedly arranged in the mounting housing 2;

[0031] The grinding and scattering assembly 6 is rotatably arranged on the top surface of the coarse screen plate 5 and is used for grinding and scattering the blocky pollen falling on the coarse screen plate 5 .

[0032] When in use, first pour the pollen from the feed port 3 into the mounting shell 2, and the pollen that is not aggregated or has a smaller aggregate volume can directly pass through the coarse screen plate 5, and after being gathered at the conical discharge port 4, enter the vibrating screen 1 for screening, while the block pollen with a larger aggregate volume is stuck on the coarse screen plate 5, and can only pass through the coarse screen plate 5 after being crushed into smaller particles by the crushing component 6, so that there is no large-volume block pollen in the pollen entering the vibrating screen 1, reducing the time required for the vibrating screen 1 to screen the pollen, thereby improving the overall screening efficiency.

[0033] In one embodiment, the grinding assembly 6 includes a rotating shaft 61 rotatably arranged on the coarse screen plate 5, a plurality of protective shells 62 uniformly arranged around the coarse screen plate 5, a grinding roller 63 rotatably arranged in the protective shell 62, and a driving motor 64 fixedly arranged on the top surface of the mounting housing 2 and drivingly connected to the end of the rotating shaft 61 extending out of the mounting housing 2. With such a design, after the driving motor 64 is started, the driving motor 64 drives the rotating shaft 61 to rotate, and the rotating shaft 61 drives the protective shell 62 and the grinding roller 63 to rotate around the rotating shaft 61. The grinding roller 63 continuously sweeps the top surface of the coarse screen plate 5 during the rotation process, and grinds the blocky pollen stuck on the coarse screen plate 5 so that it can pass through the coarse screen plate 5.

[0034] In one embodiment, the rolling roller 63 is an electric heating roller. With this design, the rolling roller 63 can heat the pollen blocks in the process of crushing the pollen blocks, reduce the moisture between the pollen, and make the pollen easier to disperse. It should be noted that the temperature of the electric heating roller should be controlled when using it. Although a higher temperature can remove the moisture between the pollen faster, it will also cause changes in various properties of the pollen, affecting its quality and subsequent processing procedures.

[0035] In one embodiment, the top of the protective shell 62 is configured as an arc surface. With this design, when pollen falls from the feed port 3 into the mounting housing 2 and is blocked by the protective shell 62, the pollen will slide down along the arc surface at the top of the protective shell 62 to the coarse screen plate 5, and will not stay on the protective shell 62, thereby preventing pollen from accumulating on the protective shell 62.

[0036] In one embodiment, the rolling roller 63 does not contact the coarse screen plate 5. The purpose of setting the rolling roller 63 is to crush the block pollen stuck on the coarse screen plate 5. If the rolling roller 63 contacts the coarse screen plate 5, although it can achieve a better crushing effect, it is very easy to crush the pollen between the two, affecting its subsequent processing, so the two are set not to contact.

[0037] In one embodiment, the conical discharge port 4 does not contact the feeding port of the vibrating screen 1. When the vibrating screen 1 is working, it will generate a large amplitude of vibration. If the conical discharge port 4 is released from the vibrating screen 1, the vibrating screen 1 will drive the conical discharge port 4 to vibrate together, and then the conical discharge port 4 drives the mounting shell 2, the coarse screen plate 5 and the grinding assembly 6 and other structures to vibrate together, and the grinding roller 63 in the grinding assembly 6 needs to maintain a certain gap with the coarse screen plate 5 to avoid crushing the pollen. The grinding roller 63 and the coarse screen plate 5 will inevitably collide with each other during the vibration process, resulting in the crushing of the pollen, so the two are set to be non-contact.

[0038] In one embodiment, the coarse screen plate 5 includes a mounting frame 51 fixedly arranged in the mounting housing 2 and a screen 52 arranged on the mounting frame 51. The mounting frame 51 is composed of an inner ring, an outer ring and a plurality of ribs evenly arranged between the inner and outer rings, and the screen 52 is arranged between adjacent ribs. With this design, the mounting frame 51 provides a stable mounting platform for the screen 52, and the plurality of ribs provide more dense support points for the screen 52, ensuring that the screen 52 will not be easily bent and deformed when subjected to the pressure of the rolling roller 63, maintaining the gap between the two, thereby ensuring the rolling effect.

[0039] In one embodiment, a hot air blower 7 is further included which is fixedly mounted on the mounting housing 2, and an air outlet of the hot air blower 7 is connected to the inner cavity of the mounting housing 2 through a connecting pipe 8. With this design, the hot air generated by the hot air blower 7 is blown into the mounting housing 2 through the connecting pipe 8 to dry the excess water attached to the pollen, further improving the grinding effect, and at the same time, the hot air can also blow off the non-block pollen attached to the coarse screen plate 5.

[0040] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0041] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0042] In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
