Description

Technical Field

[0001] The utility model relates to the technical field of filtration separation, in particular to a filtration separation device capable of automatic cleaning. Background Art

[0002] In food processing enterprises, in order to extract the required substances from some raw materials, extraction separation or other separation technologies are usually required for application in other occasions. Extraction separation is the use of solvents to separate components in solid mixtures, such as using water to extract sugars from beets; using alcohol to extract soybean oil from soybeans to increase oil yield; using water to extract active ingredients from traditional Chinese medicine to prepare fluid extracts is called "leaching" or "leaching".

[0003] In the mushroom extraction process, the mushrooms are usually cut into small particles and then mixed with a solvent, and finally filtered out. The existing filtration uses gauze for filtration, but since the gauze has small pores, the filtration efficiency is low. There are also methods of filtration using a filter net, but since the filter net is stationary during filtration, if there are too many solid impurities, the filter net is easily blocked and needs to be manually cleaned, which is not only cumbersome, but also affects the efficiency of filtration separation.

[0004] After searching, it was found that the Chinese utility model patent with patent number CN202121521422.5 discloses a device for automatic cleaning of sewage filtration, including a housing, a filter separation structure and a filter screen automatic cleaning structure. The filter separation structure and the filter screen automatic cleaning structure are installed in the housing. The filter separation structure is mainly composed of a circular filter screen installation groove, a fixed rod, a filter screen positioning plate and a filter screen and is columnar. The filter screen automatic cleaning structure is mainly composed of a chassis, a connecting rod, a movable plate, an arc brush and a fixed threaded rod. The movable plate is located inside the filter separation structure. During filtering, the filter screen automatic cleaning structure is raised to the top by rotating the fixed threaded rod to achieve bottom closure, and the sewage is discharged from one side of the housing after passing through the filter separation structure; when the valve is closed for cleaning, the filter screen automatic cleaning structure is driven to move up and down by rotating the fixed threaded rod, which realizes automatic cleaning of the filter screen on the one hand, and collects the separated filter residue in a unified manner on the other hand, shortening the time consumed by replacing and cleaning the filter screen, reducing costs and improving work efficiency.

[0005] However, according to the analysis of the above technical solution, during filtration, since the sewage inlet pipe is set at the top, the liquid enters from the top of the filter separation structure during feeding and will preferentially flow to the bottom. However, the bottom chassis can move up and down. Although the chassis is fixed at the bottom of the filter separation structure during filtration, there is still a gap, and part of the liquid may flow out from the gap, affecting the processing environment, and the device needs to close the liquid inlet when cleaning, so continuous filtration and separation cannot be achieved. Utility Model Content

[0006] Therefore, in order to solve the above-mentioned deficiencies, the utility model provides an automatically cleaned filtering and separation device, in which a slag discharge pipe is arranged above the filter disc. During filtration, liquid passes through the filter disc and is discharged from the discharge pipe below, while solid impurities remain on the filter disc. Combined with the lifting mechanism, the solid impurities on the filter disc can be transported upward and finally discharged from the slag discharge pipe. This method not only realizes the automatic cleaning of the filter screen and prevents liquid leakage, but also realizes continuous filtering and separation.

[0007] The utility model is implemented by constructing a filtering and separating device capable of automatic cleaning, comprising a separation cylinder, which is vertically supported by supporting feet;

[0008] A filter disc is arranged inside the separation cylinder;

[0009] A liquid discharge pipe is arranged on the side wall of the separation cylinder at the lower end of the filter disc and is connected with the interior;

[0010] A slag discharge pipe is arranged on the side wall of the separation cylinder at the upper end of the filter disc and is connected to the interior;

[0011] The lifting mechanism is rotatably arranged in the separation cylinder above the filter disc and is used to lift and transport the solid impurities filtered out from the filter disc to the slag discharge pipe;

[0012] The feed pipe of the separation cylinder is arranged above the filter disc and is connected with the lifting mechanism.

[0013] Specifically, the lifting mechanism includes a driving rod and a rotating rod, one end of the driving rod passes through the center of the filter disc and extends to the outside of the bottom of the separation cylinder, a bearing and a seal are provided at the position where the driving rod contacts the separation cylinder and the filter disc, the other end of the driving rod is coaxially connected with the end of the rotating rod, a center hole is opened at the top of the rotating rod and is connected to the feed pipe through the center hole, a discharge hole is opened on the bottom side of the center hole of the rotating rod, and a spiral blade is provided on the outer side of the rotating rod.

[0014] Specifically, the top end of the rotating rod is connected to the feed pipe through a rotating connector, and the feed pipe passes through the top or side of the separation cylinder to communicate with external equipment.

[0015] Specifically, the outer diameter of the spiral blade is adapted to the inner wall of the separation barrel, and the highest height of the spiral blade is at the position of the slag discharge pipe or above the slag discharge pipe.

[0016] Specifically, a plurality of filter holes having the same diameter as the filter holes of the filter disc are evenly formed on the spiral blade.

[0017] The utility model has the following beneficial effects:

[0018] The filtration and separation device sets the discharge pipe above the filter disc. During filtration, liquid passes through the filter disc and is discharged from the discharge pipe below, while solid impurities remain on the filter disc. Combined with the lifting mechanism, the solid impurities on the filter disc can be transported upward and finally discharged from the discharge pipe. This method not only realizes automatic cleaning of the filter screen and prevents liquid leakage, but also realizes continuous filtration and separation. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solution of the present invention is further specifically described below through specific embodiments in combination with the accompanying drawings; it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not intended to limit the present invention in any way; the accompanying drawings in the present invention are only used to assist in the description of the embodiments and to facilitate understanding, and are not intended to limit the present invention in any way.

[0027] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them, and are not used to limit the conditions under which the present invention can be implemented. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical contents disclosed in the present invention without affecting the effects and purposes that can be achieved by the present invention.

[0028] As described in the background technology, the filter screen of the existing filtration and separation device is easily clogged during use, requiring frequent manual cleaning, which is time-consuming and labor-intensive. Some filtration and separation devices that can be automatically cleaned have leakage problems and cannot achieve filtering during the cleaning process.

[0029] For the reasons stated above, please refer to the attached Figure 1 ~Attached Figure 4 , the utility model provides a filtering and separating device capable of automatic cleaning, comprising a separation cylinder 4, which is vertically supported by a support leg 5;

[0030] The filter disc 9 is arranged inside the separation cylinder 4;

[0031] A drain pipe 6 is provided on the side wall of the separation cylinder 4 at the lower end of the filter disc 9 and is connected to the interior;

[0032] A slag discharge pipe 7 is arranged on the side wall of the separation cylinder 4 at the upper end of the filter plate 9 and is connected with the interior;

[0033] The lifting mechanism is rotatably arranged in the separation cylinder 4 above the filter disc 9 and is used to lift and transport the solid impurities filtered out of the filter disc 9 to the slag discharge pipe 7;

[0034] The feed pipe 13 of the separation cylinder 4 is arranged above the filter disc 9 and is connected with the lifting mechanism.

[0035] Specifically, the lifting mechanism includes a driving rod 8 and a rotating rod 10. One end of the driving rod 8 passes through the center of the filter disc 9 and extends to the outside of the bottom of the separation cylinder 4. Bearings and seals are provided at the position where the driving rod 8 contacts the separation cylinder 4 and the filter disc 9. The other end of the driving rod 8 is coaxially connected to the end of the rotating rod 10. A center hole is opened at the top of the rotating rod 10 and is connected to the feed pipe 13 through the center hole. A discharge hole 12 is opened on the bottom side of the center hole of the rotating rod 10, and a spiral blade 11 is provided on the outer surface of the rotating rod 10.

[0036] Through the above technical features, the center hole at the top of the rotating rod is provided to facilitate the connection between the top and the feed pipe, thereby facilitating the solid-liquid mixture to enter the separation cylinder from the center hole of the rotating rod during filtration, preventing the liquid from entering the slag discharge pipe and causing leakage.

[0037] Furthermore, one end of the driving rod located outside the bottom of the separation cylinder can be connected to an external driving motor through a transmission mechanism (such as a belt transmission mechanism) to facilitate driving the internal rotating rod to rotate.

[0038] Specifically, the top end of the rotating rod 10 is connected to the feed pipe 13 through a rotating connector, and the feed pipe 13 passes through the top or side of the separation cylinder 4 to communicate with external equipment.

[0039] Through the above technical features, by arranging rotating connectors at the ends of the rotating rod and the feeding pipe, it is not only convenient to connect the rotating rod and the feeding pipe, but also can improve the stability of the rotating rod during rotation.

[0040] Specifically, the outer diameter of the spiral blade 11 is adapted to the inner wall of the separation barrel 4 , and the highest height of the spiral blade 11 is at the position of the slag discharge pipe 7 or above the slag discharge pipe 7 .

[0041] Through the above technical features, the height and outer diameter of the spiral blades are set to facilitate the lifting and transportation of internal solid impurities so as to facilitate their discharge to the slag discharge pipe.

[0042] Specifically, the spiral blade 11 is evenly provided with a plurality of filter holes having the same diameter as the filter holes of the filter disc 9 .

[0043] Through the above technical features, the filter holes on the spiral blades are arranged to facilitate further filtering of solid impurities, effectively improving the filtering quality while reducing the leakage problem.

[0044] Furthermore, the feed pipe 13 in the filtering and separating device is connected to the bottom discharge ports of multiple external extraction tanks 2 (or other mixing tanks) through the connecting pipe 3 , and the extraction tanks 2 can be placed on the working platform 1 .

[0045] When the device is in use, first the feed pipe 13 discharges the material into the central hole of the rotating rod 10, and at the same time the external drive motor drives the transmission mechanism to drive the drive rod 8 to rotate, thereby driving the rotating rod 10 to rotate, and the material flows downward in the central hole of the rotating rod 10, and after flowing to the lowest point, it is discharged from the side discharge hole 12 (under the action of centrifugal force) to the top of the filter plate 9 for filtration, and the liquid passes through the filter plate 9 and is discharged from the discharge pipe 6, while the solid impurities remain on the filter plate 9. As the rotating rod 10 rotates, the external spiral blades 11 scrape the solid impurities on the filter plate 9 upward, and as the spiral blades 11 rotate, they are lifted upward to the slag discharge pipe 7 for discharge, and at the same time, the liquid that may remain in the solid impurities will also pass through the filter holes on the spiral blades 11 and fall down, effectively ensuring solid-liquid separation.

[0046] It is worth noting that in order to facilitate the spiral blade to transport impurities on the filter disc 9, the lowest height of the spiral blade can be close to the filter disc 9, and the discharge hole 12 can be opened on the rotating rod 10 in the middle position of the spiral blade 11.

[0047] The above description is a detailed description of the preferred feasible embodiment of the utility model, but the embodiment is not used to limit the scope of the patent application of the utility model. All equivalent changes or modified changes completed under the technical spirit suggested by the utility model should fall within the patent scope covered by the utility model.
