Description

Technical Field

[0001] This utility model relates to the field of silkworm pupa processing equipment technology, and in particular to a crusher for rapidly crushing solid materials with high oil content. Background Technology

[0002] The refining of silkworm pupae includes extracting and concentrating proteins, separating proteins, and peptides. The primary process is to pulverize the granular silkworm pupae to allow for efficient separation and purification of silkworm pupa proteins and silkworm pupa oil in subsequent processes. However, most pulverizers currently suffer from the following three problems:

[0003] 1. Silkworm pupae have a high oil content, which can easily cause blockages in hammer mills and liquid nitrogen cryogenic mills, resulting in significant damage to the equipment and production capacity.

[0004] 2. Some impurities such as cocoons and silk may remain in the silkworm pupae, which are difficult to completely remove by manual sieving, affecting the overall quality;

[0005] 3. The equipment itself has a low processing capacity, and the efficiency of crushing silkworm pupae is not as expected.

[0006] This greatly limits the efficient production of silkworm pupa protein and increases the cost of production and processing. Therefore, it is urgent to solve this problem. If the crushing capacity can be improved and the crushing process can be kept unclogged, the stable and continuous production of high-quality silkworm pupa protein can be achieved, creating value. Utility Model Content

[0007] In view of this, this utility model proposes a crusher for rapidly crushing solid materials with high oil content.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A high-oil-content solid material crusher for rapid crushing includes a frame. From the lower right to the top of the frame, a connected discharge port, a roller crushing assembly, a screening assembly, and a vacuum suction assembly are arranged sequentially. The vacuum suction assembly has a feed port on its side. The roller crushing assembly is composed of several rollers arranged vertically, with the upper roller being a toothed roller and the lower roller being a grooved roller.

[0010] As a further improvement to the above technical solution:

[0011] An optimized version of the above technical solution is that the vacuum suction assembly includes a vacuum suction tank disposed on the upper end of the screening assembly, a pressure gauge and a vacuum pump disposed on the upper end of the vacuum tank, and a feed inlet disposed on the bottom side of the vacuum suction tank. The feed inlet is connected to an external material container through a feed pipe.

[0012] An optimized version of the above technical solution is that the screening assembly includes a screening tank disposed on the upper end of the roller crushing assembly, a filter screen support disposed at the upper opening of the screening tank, and a filter screen disposed at the lower end of the filter screen support.

[0013] An optimized version of the above technical solution is that the filter support is in the shape of a frustum.

[0014] An optimized version of the above technical solution is that the roller crushing assembly includes a roller support frame and a drive motor mounted on the frame, and a roller rotatably mounted on the roller support frame. The drive motor is connected to the roller via a chain and gears.

[0015] An optimized version of the above technical solution is that a feeding hopper is provided at the upper end of the roller support frame, and the upper end of the feeding hopper is fixedly connected to and communicates with the screening component.

[0016] An optimized version of the above technical solution is that the roller support frame is provided with roller adjustment handles on its side, and the roller adjustment handles correspond one-to-one with the roller wheels.

[0017] An optimized version of the above technical solution is that the number of toothed rollers is one pair, and the number of grooved rollers is two pairs.

[0018] An optimized version of the above technical solution is that the spacing between the same pair of rollers decreases sequentially from top to bottom.

[0019] An optimized version of the above technical solution includes a pressure control tube, which is disposed on the screening assembly or the vacuum suction assembly.

[0020] Compared with existing technologies, the beneficial effects of this utility model are:

[0021] This invention uses a vacuum feeding method, which makes the feeding speed fast and prevents adhesion or blockage in the pipeline. At the same time, a filter component is used to filter impurities, ensuring the quality of the crushed material. In addition, multiple pairs of different rollers are used for crushing.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figure 1 To be continued Figure 3 As shown, the structure of this embodiment includes three main parts: a vacuum feeder for feeding materials, a filter assembly for filtering impurities, and a multi-roller crushing device for crushing.

[0033] The main body of the equipment in this technical solution is a vertical stainless steel structure to withstand the impact and pressure brought about by high-speed rotation and high-torque crushing.

[0034] I. For the multi-roller crushing device used for crushing, it is mainly set on the frame 1. Its main structure is a roller support frame 3 fixedly set on the frame 1. Inside the roller support frame 3, there are three pairs of rollers that can rotate in opposite directions from bottom to top (the specific structure is that one end is fixed by a bearing and the other end is fixed by two meshing gears, thereby realizing synchronous reverse rotation so that the material can be squeezed). Specifically, there are two pairs of grooved rollers 8 at the bottom and one pair of toothed rollers 7 at the top. The number of them can be freely changed during the design, but it is necessary to ensure that the upper end is a toothed roller 7 and the lower end is a grooved roller 8.

[0035] Toothed rollers can accelerate the crushing speed of silkworm pupae and prevent oil spillage or clumping during the crushing process. Untoothed rollers can ensure that all materials are crushed and also avoid the situation where materials spill out due to excessive speed. To achieve this function, the distance between rollers from top to bottom should be gradually reduced. For easy adjustment, roller adjustment handles 6 are provided on the outside of the roller support frame 3. The roller adjustment handles 6 correspond to and are connected to each pair of rollers, thereby realizing the adjustment of the roller distance (the specific structure is the same as the existing technology and does not need to be described in detail).

[0036] Meanwhile, a drive motor 4 is installed on the frame 1, equipped with a gearbox, and connected to the gears at both ends of the rollers via a chain to drive the rollers to rotate (this connection method is existing technology, mainly because one gear on the same pair of rollers is a single gear and the other is a double gear, so that the same pair of rollers can mesh with each other and can be connected to the drive motor 4 via a chain for drive).

[0037] A discharge port 2 is provided on the lower side of the roller support frame, and the crushed material is discharged from the discharge port 2 through free fall.

[0038] Meanwhile, a feeding hopper 5 is provided at the upper end of the roller support frame to collect materials in a concentrated manner, so that they can be fed into the roller support frame for crushing.

[0039] II. The filter assembly for filtering impurities is fixedly installed above the feed hopper 5. Specifically, it includes a screening tank 9 fixedly installed above the feed hopper 5. A filter screen support 10 is installed at the opening at the upper end of the screening tank 9. The filter screen support 10 is in the shape of an inverted frustum, which allows the material to concentrate inward. At the same time, a filter screen 11 is installed at the opening at the lower end of the filter screen support 10 to facilitate the separation of silkworm pupae from impurities. It should be noted that the impurities removed are mostly large impurities. Some residual cocoons, silk, and other impurities in the silkworm pupae are also mostly in clumps, so they can be filtered. Meanwhile, the impurities are centrally processed after crushing.

[0040] 3. A vacuum feeder for feeding materials is installed on the upper end of the screening tank 9. Specifically, a vacuum feed tank 13 is installed on the upper end of the screening tank 9. A pressure gauge 14 and a vacuum pump 15 are installed on the upper end of the vacuum feed tank 13 to detect pressure and perform vacuuming. A feed inlet 16 is provided on the side of the vacuum feed tank 13, which is connected to the material holding container through a material pipeline.

[0041] The point that needs clarification here is that vacuum extraction of materials is not a continuous operation of the vacuum pump, but an intermittent extraction. This allows the material to be drawn into the vacuum suction tank 13. When the pump stops, the material falls freely into the screening assembly. To achieve this, the pressure difference between the inside and outside is balanced after the pump stops. Therefore, as shown in the attached diagram, a pressure control pipe 12 is installed on the side of the screening tank 9, allowing air to enter the interior after the vacuum pump 15 stops, allowing the material to fall freely. It is shown in the attached diagram as being installed on the screening tank 9, but it can also be installed on the vacuum suction tank 13.

[0042] The process of using this utility model:

[0043] 1. First, turn on the drive motor 4 of the roller crusher so that multiple pairs of rollers rotate inward;

[0044] 2. Place the silkworm pupa raw material into the material holding container (any box will do), and connect the material pipe to the material holding container and the inlet 16;

[0045] 3. Turn on the vacuum pump 15, and the material will enter the vacuum suction tank 13 under the action of suction.

[0046] 4. After the vacuum pump 15 has been working for a certain period of time (set by the user), it stops working. Since the density of impurities and silkworm pupae is different, the feeding rate is different under the action of wind, and the free fall rate is also different. Impurities can be screened out through the filter screen 11 to ensure that the material entering the feed inlet 16 is silkworm pupae, and then enters the crushing system through free fall.

[0047] 5. Adjust the gap and rotation speed between the rollers in advance, observe the crushed material, the processing capacity is about 400 kg / h, and place bags at the two discharge ports in advance to collect the material;

[0048] After crushing, check the material obtained from outlet 2. There are no obvious large particles of impurities, and the particle size is uniform, about 20-30 mesh. Check the material from filter screen 11. There are no silkworm pupa particles, and most of them are cocoons, silk, and silkworm pupa skins. This indicates that the operating speed of the equipment and the gap between the rollers are normal and production can proceed.

[0049] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
