Description

Technical Field

[0001] The utility model relates to the technical field of sesame oil production equipment, in particular to sesame oil filtering equipment, specifically to a sesame oil multi-stage filtering device. Background Art

[0002] Sesame oil is a seasoning oil commonly used in daily life. Due to its strong aroma, it is widely used in making soups and cooking. Since sesame oil is made from pressed sesame seeds, it contains some solid sesame meal in the oil. In order to avoid affecting the taste and improve the quality of the oil, the sesame oil needs to be filtered.

[0003] In the current sesame oil production process, single-stage filtration is usually used. However, since sesame oil has a certain viscosity, if the mesh diameter of the filter is small, it will affect the efficiency of the sesame oil flowing downward, thereby affecting the filtration efficiency and causing the filter to be blocked; if the mesh diameter of the filter is increased, it will lead to incomplete filtration, and the filtered sesame oil will still contain a large amount of solid impurities.

[0004] In the prior art, the primary goal is usually to ensure the quality of oil products, so the mesh size of the filter is relatively small. In order to solve the problem of easy clogging, a solution of convenient filter replacement is adopted. However, when replacing the filter, the machine needs to be shut down, which is not conducive to improving production efficiency. Utility Model Content

[0005] Aiming at the deficiencies of the prior art, the utility model provides a sesame oil multi-stage filtering device, which adopts a multi-stage filtering method, greatly alleviates the problem of filter screen clogging and improves the continuity of production.

[0006] The utility model is realized by the following technical scheme, and provides a sesame oil multi-stage filtering device, comprising a main frame, a rotating shaft rotatably arranged on the main frame, and a driving device for driving the rotating shaft to rotate, wherein the rotating shaft is vertically arranged, and a first driving gear, a driving pulley, and a second driving gear are fixedly mounted on the rotating shaft in sequence from top to bottom;

[0007] A fixed shaft parallel to the rotating shaft is fixed on the main frame, and three layers of filter sieve discs are rotatably arranged on the fixed shaft from top to bottom in sequence, and the filter sieve disc comprises a cylinder body and a sesame oil filter screen fixedly connected to the lower end of the cylinder body, and a shaft sleeve is fixedly provided at the center of the sesame oil filter screen, and the shaft sleeve is rotatably connected to the fixed shaft; the mesh apertures of each layer of the filter sieve disc decrease in sequence from top to bottom, and a first driven gear meshed with the first driving gear is fixedly sleeved on the outer side of the cylinder body of the upper filter sieve disc, a driven pulley connected to the driving pulley through a belt drive is fixedly sleeved on the outer side of the cylinder body of the middle filter sieve disc, and a second driven gear meshed with the second driving gear is fixedly sleeved on the outer side of the cylinder body of the lower filter sieve disc.

[0008] This solution arranges filter screens with successively smaller mesh sizes so that each layer of filter screens can intercept solid impurities of corresponding size grades respectively, thereby avoiding the situation where impurities of all sizes accumulate on the same filter screen and cause easy blockage. In addition, the rotating shaft is driven to rotate by a driving device, and the filter sieve plates of each layer are driven to rotate by gear meshing and belt transmission. The upper and middle filter sieve plates rotate in opposite directions, and the middle and lower filter sieve plates rotate in opposite directions, so that sesame oil flows relative to the sieve in the middle and lower filter sieve plates, avoiding solid impurities from being stationary in the mesh of the sieve, improving the passage efficiency of oil products, and further improving the anti-blocking effect of the filter screen.

[0009] As an optimization, an oil receiving funnel located below the lower filter sieve plate is also installed on the fixed shaft, the upper diameter of the oil receiving funnel is larger than the lower diameter, and the vertical projections of each of the cylinders are located within the vertical projection area of ​​the upper opening of the oil receiving funnel. This optimization solution is convenient for receiving the filtered sesame oil by setting the oil receiving funnel, facilitating the collection of the filtered sesame oil, and preventing the sesame oil from scattering outside the oil receiving funnel.

[0010] As an optimization, the oil receiving funnel includes a bucket body and an adapter sleeve located in the bucket body, the outer side of the adapter sleeve is fixedly connected to the inner wall of the bucket body through a radiation rod, the inner hole of the adapter sleeve is coaxially fixedly connected with a threaded sleeve, and the inner hole of the threaded sleeve is connected to the fixed shaft through a thread; the upper end of the bucket body is provided with a vertical section extending to the outside of the lower filter sieve plate. The bucket body and the adapter sleeve of this optimization solution are fixedly connected as a whole through the radiation rod, the structure is simple, and it avoids occupying too much space inside the bucket body. The oil receiving funnel is connected to the fixed shaft through a thread as a whole, which is convenient for installation and disassembly, and it is convenient to adjust the distance between the oil receiving funnel and the lower filter sieve plate.

[0011] As an optimization, a limiting bottom plate located below the fixed shaft is fixed at the bottom of the adapter sleeve, and the vertical distance between the limiting bottom plate and the fixed shaft is smaller than the distance between the radiation rod and the lower filter sieve plate. This optimization scheme sets a limiting bottom plate to limit the upper limit position of the docking oil funnel, so as to avoid touching the lower filter sieve plate and affecting the rotation of the lower filter sieve plate.

[0012] As an optimization, the upper part of the outer side surface of the middle filter sieve disc sleeve and the upper part of the outer side surface of the lower filter sieve disc sleeve are both conical surfaces that are small at the top and large at the bottom. The bottom of the upper filter sieve disc sleeve is fixedly connected to a first oil shield extending downward to the conical surface of the middle filter sieve disc sleeve, and the bottom of the middle filter sieve disc sleeve is fixedly connected to a second oil shield extending downward to the conical surface of the lower filter sieve disc sleeve. This optimization scheme provides a first oil shield and a second oil shield, and provides a conical surface on the sleeve, so that the oil shield blocks the falling oil and prevents sesame oil from entering between the sleeve and the fixed shaft.

[0013] As an optimization, the main frame is also fixed with an oil inlet pipe located just above the upper filter screen. This optimization scheme ensures the accuracy of the oil to be filtered to the upper filter screen by setting the oil inlet pipe, and because the oil inlet pipe is fixed, the sesame oil in the upper filter screen will also flow, improving the anti-blocking effect and the oil passing efficiency.

[0014] The beneficial effects of the utility model are as follows: by setting three layers of sesame oil filter screens with successively smaller mesh sizes, solid impurities of different specifications can be filtered separately, the filter screen blockage is reduced, thereby reducing the number of shutdowns for cleaning solid impurities and ensuring the continuity of production; by setting the steering directions of two adjacent layers of filter screen discs to be opposite, the sesame oil is caused to flow relative to the filter screen disc, preventing the solid impurities from being stationary in the screen mesh holes, thereby avoiding the filter screen blockage and improving the efficiency of sesame oil passing through the filter screen.

DETAILED DESCRIPTION

[0018] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0019] like Figure 1 The sesame oil multi-stage filtering device shown in the figure comprises a main frame 13, a rotating shaft 11 rotatably arranged on the main frame, and a driving device 17 for driving the rotating shaft to rotate. The driving device in this embodiment is an electric motor, and the output shaft of the electric motor is coaxially fixedly connected with the rotating shaft, thereby driving the rotating shaft to rotate. The rotating shaft 11 is arranged in the vertical direction, and a first driving gear 15, a driving pulley 14 and a second driving gear 12 are fixedly installed on the rotating shaft from top to bottom.

[0020] The main frame is fixed with a fixed shaft 1 parallel to the rotating shaft 11, and three layers of filter screen discs 3 are arranged on the fixed shaft 1 in a rotational manner from top to bottom, namely, an upper filter screen disc, a middle filter screen disc and a lower filter screen disc, and the main frame is fixed with an oil inlet pipe 16 located just above the upper filter screen disc. Specifically, the filter screen disc 3 includes a cylinder body and a circular sesame oil filter screen fixed to the lower end of the cylinder body, the side wall of the cylinder body forms a barrier for sesame oil, and a sleeve 2 is fixed at the center of the sesame oil filter screen. The sleeve 2 is rotatably connected to the fixed shaft 1 through a bearing, and a through hole matching the outer diameter of the sleeve is opened at the center of the screen, and the through hole wall is welded to the sleeve as a whole.

[0021] The mesh apertures of each layer of filter sieve disc decrease from top to bottom, and the mesh areas of each layer of filter sieve disc are opposite to each other in the vertical direction. A first driven gear 4 meshing with the first driving gear 15 is fixedly sleeved on the outer side of the cylinder body of the upper filter sieve disc, a driven pulley 5 connected to the driving pulley 14 through a belt drive is fixedly sleeved on the outer side of the cylinder body of the middle filter sieve disc, and a second driven gear 6 meshing with the second driving gear 12 is fixedly sleeved on the outer side of the cylinder body of the lower filter sieve disc. By setting the first driven gear, the driven pulley and the second driven gear, not only the transmission connection is realized, so that the filter sieve discs of the two adjacent layers turn in opposite directions, but also the structural strength of each filter sieve disc is increased.

[0022] In order to facilitate the collection of filtered sesame oil, an oil collecting funnel 8 located below the lower filter sieve plate is also installed on the fixed shaft 1 of this embodiment. The upper diameter of the oil collecting funnel is larger than the lower diameter, and the vertical projections of each of the cylinders are located within the vertical projection area of ​​the upper opening of the oil collecting funnel.

[0023] Specifically, the oil receiving funnel includes a bucket body and an adapter sleeve 9 located inside the bucket body. The outer side of the adapter sleeve 9 is fixedly connected to the inner wall of the bucket body through a radiation rod 10. Each radiation rod is evenly distributed along the circumference. One end of the radiation rod is fixedly connected to the adapter sleeve, and the other end is fixedly connected to the bucket body. There are three radiation rods in this embodiment, which not only ensures structural stability, but also avoids increasing the weight of the oil receiving funnel due to too many radiation rods. The inner hole of the adapter sleeve is coaxially fixed with a threaded sleeve 7, and the inner hole of the threaded sleeve 7 is connected to the fixed shaft 1 through a thread.

[0024] The upper end of the bucket body is provided with a vertical section extending to the outer side of the lower filter sieve plate to prevent the sesame oil from being thrown out of the bucket body due to the rotation of the filter sieve plate.

[0025] The bottom of the adapter sleeve is fixed with a limit bottom plate located below the fixed shaft, and the vertical distance between the limit bottom plate and the fixed shaft is smaller than the distance between the radiation rod and the lower filter screen. On the one hand, the limit bottom plate is used to prevent the radiation rod from touching the lower filter screen when the oil receiving funnel is installed. On the other hand, a cavity structure with a bottom seal is formed inside the adapter sleeve, which can receive the oil flowing down along the fixed shaft and prevent the oil flowing down along the fixed shaft from entering the bucket body and causing pollution.

[0026] The upper part of the outer side of the filter screen disc sleeve of the middle layer and the upper part of the outer side of the filter screen disc sleeve of the lower layer are both conical surfaces with a small top and a large bottom. The bottom of the filter screen disc sleeve of the upper layer is fixedly connected by bolts with a first oil shield 18 extending downward to the conical surface of the filter screen disc sleeve of the middle layer, and the bottom of the filter screen disc sleeve of the middle layer is fixedly connected by bolts with a second oil shield 19 extending downward to the conical surface of the filter screen disc sleeve of the lower layer. By providing the first oil shield and the second oil shield, oil is prevented from entering between the sleeve and the fixed shaft, and the splashed oil flows back along the conical surface of the sleeve, thereby reducing oil waste.

[0027] When in use, the sesame oil to be filtered is injected into the upper filter sieve plate through the oil inlet pipe, the rotating shaft is driven to rotate by the driving device, and the upper and middle filter sieve plates are turned in opposite directions through gear transmission and belt transmission, and the middle and lower filter sieve plates are turned in opposite directions, so that the sesame oil in each filter sieve plate flows relative to the filter screen, forming a certain flushing on the filter screen, avoiding the blockage of the filter screen mesh due to the stationary solid impurities, and improving the efficiency of the downward flow of the sesame oil; after three-stage filtration, the sesame oil falls into the oil receiving funnel, and since the lower opening of the oil receiving funnel is small, it is convenient for oil collection.

[0028] Of course, the above description is not limited to the above examples. The technical features not described in the present invention can be achieved by or by adopting the existing technology, which will not be repeated here.
