Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a filtering device for liquor processing. Background Art

[0002] When processing liquor, a filtering device is required to remove suspended solid particles, impurities and sediments. At present, the existing filtering device for liquor processing often adopts the following structure, including a filter housing, a filter cavity is arranged inside the filter housing, a filter disc (or filter net) arranged vertically or horizontally is installed inside the filter cavity, a plurality of filter holes are arranged on the filter disc, and the filter disc divides the filter cavity into a feed cavity and a discharge cavity, the feed cavity is connected to a feed pipe, and the discharge cavity is connected to a discharge pipe. When filtering liquor, the solid particles in the liquor are easy to block the filter holes, and manual cleaning is required to ensure the normal use of the filtering device. The manual cleaning method has high labor intensity and certain inconveniences. In addition, the impurities filtered in the liquor are mostly grain residues, and the existing conventional filtering device cannot collect the impurities filtered in the liquor for secondary use, which leads to food waste.

[0003] For example, the patent document with the announcement number CN203329455U discloses a new type of white alcohol tight filter device, including a cylinder, a filter element, a water inlet, a water outlet and a head. Several filter elements are arranged on the inner side of the cylinder, and the upper and lower ends of the cylinder are respectively provided with fixed flower plates, and several fixed holes are arranged on the fixed flower plates. A filter element shaft is movably arranged in the fixed holes of the fixed flower plates, and the filter element shaft is spirally plugged. The filter element is sleeved on the filter element shaft, and a central pull rod is arranged between the fixed flower plate at the upper end of the cylinder and the head. The utility model solves the problem that the central fixed shaft of the traditional white alcohol tight filter device rusts and falls off after being immersed in wine for a long time. At the same time, the filter element is movably arranged, which is convenient for installation and later maintenance. The various opening and closing methods of the head and the cylinder can also be freely selected by the manufacturer according to production needs. This scheme improves the convenience of the filter element in the later disassembly and maintenance to a certain extent, but it does not fundamentally solve the problem that the filter holes are easy to be blocked, and it does not consider collecting and reusing the grain residue filtered in the white wine.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 to Figure 6The utility model comprises a filter housing 1, a filter chamber 101 is arranged inside the filter housing 1, a filter disc 9 is installed in the filter chamber 101, a plurality of first filter holes 902 are arranged on the filter disc 9, the filter disc 9 divides the filter chamber 101 into an upper feed chamber and a lower discharge chamber, a feed pipe 3 is connected to the side wall of the upper feed chamber (in order to effectively utilize the volume of the filter chamber 101, the connection point of the feed pipe 3 is generally preferably designed at the top of the side wall of the upper feed chamber), and a discharge pipe is connected to the lower discharge chamber. The top of the filter housing 1 is an opening structure interpenetrating with the upper feed chamber, and a storage disc 4 is sealed and connected to the top of the filter housing 1. The storage disc 4 comprises a storage disc bottom plate 402 for contacting with the top surface of the filter housing 1 and a storage disc cylinder 401 arranged on the upper surface of the storage disc bottom plate 402. The bottom of the storage disc 4 is connected with a storage disc for discharging the residue in the storage disc 4 to the outside of the storage disc 4 and the outside of the filter housing 1. The slag chute 5; the inner cavity of the storage disk 4 is equipped with a rotatable anti-blocking shaft 10 with a vertical axis, the anti-blocking shaft 10 includes a transmission shaft 1001, the outer wall of the transmission shaft 1001 is fixedly connected with a material guide blade 1002 which is spirally distributed around the axis of the transmission shaft 1001, and a plurality of second filtering holes 1003 are arranged on the material guide blade 1002, and the lower part of the transmission shaft 1001 and the material guide blade 1002 passes through the storage disk bottom plate 402 and extends to the filter cavity In the upper feed cavity of 101 (which is equivalent to a hole in the middle of the storage disk bottom plate 402 for the anti-jamming shaft 10 to pass through), the guide blade 1002 is used to guide the slag from the upper feed cavity of the filter cavity 101 to the upper area of ​​the storage disk 4 (which is the rotation direction of the transmission shaft 1001 during operation matches it), and a support plate 7 is fixedly provided above the storage disk 4 through a support mechanism, and a servo motor 8 for driving the anti-jamming shaft 10 to rotate is fixedly provided on the support plate 7. When filtering the liquor, the granular impurities on the filter disc 9 are stirred by the rotation of the anti-blocking shaft 10, and the granular impurities are prevented from blocking the first filter hole 902 on the surface of the filter disc 9 as much as possible. At the same time, the guide blades 1002 on the surface of the transmission shaft 1001 can transport the granular impurities filtered inside the liquor into the inner cavity of the storage disc 4, and discharge the granular impurities through the slag chute 5 for recycling, so as to prevent the waste of grain residues. At the same time, the second filter holes 1003 on the guide blades 1002 filter out the liquor, and prevent the liquor from being driven out when the granular impurities are recycled by the slag chute 5. It can be understood that the "slag chute 5" is a chute that uses the gravity of the slag material to discharge slag, as long as the outlet of the chute body is lower than the inlet and the inner cavity flow channel is kept unobstructed, and a straight chute arranged obliquely can usually be used.

[0023] For ease of processing and facilitating the filtration of particulate impurities, the first filter hole 902 and the second filter hole 1003 are preferably circular holes. To give full play to the guiding function of the guide blade 1002, the aperture of the second filter hole 1003 is preferably designed to be no larger than the aperture of the first filter hole 902, and can usually be designed to be equal in aperture.

[0024] In order to give full play to the guiding function of the guiding blades 1002 , the side wall of the filter housing 1 and the storage disk body 401 are cylindrical bodies with the same inner diameter, and are arranged coaxially with the anti-blocking shaft 10 .

[0025] The inlet end of the slag chute 5 is designed at the bottom of the storage disk 4, which means that it can be the bottom of the storage disk cylinder 401 or the storage disk bottom plate 402. In the preferred embodiment in which the side wall of the filter housing 1 and the storage disk cylinder 401 are cylindrical bodies with the same inner diameter, the connection port of the slag chute 5 and the storage disk 4 is set at the intersection of the storage disk cylinder 401 and the storage disk bottom plate 402 to facilitate slag discharge.

[0026] In order to give full play to the stirring effect of the anti-blocking shaft 10, the filter disc 9 includes a circular bottom plate and a conical cylinder 901 arranged around the edge of the circular bottom plate. The conical cylinder 901 is coaxial with the circular bottom plate, and the upper inner diameter of the conical cylinder 901 is larger than the lower inner diameter.

[0027] In order to simplify the driving mechanism of the anti-blocking shaft 10 and facilitate installation and implementation, a shaft connection through hole 701 is provided at the top of the support plate 7 at the position where the servo motor 8 is fixedly connected, and the upper end of the anti-blocking shaft 10 passes through the shaft connection through hole 701 and is transmission-connected to the output shaft at the bottom of the servo motor 8. The shaft connection through hole 701 can generally be a circular through hole.

[0028] Preferably, the lower end of the anti-blocking shaft 10 is rotatably connected to the upper surface of the filter disc 9. This can improve the stability of the anti-blocking shaft 10 (the lower end has a support structure), and on the other hand, the anti-blocking shaft 10 can also more fully play the stirring and guiding role (the axial length of the anti-blocking shaft 10 in the filter cavity 101 can reach the theoretical maximum value).

[0029] The support mechanism can be independently provided or integrated on the filter housing 1 or the storage disk body 401. For the sake of simplicity and reliability, the support mechanism in the preferred embodiment of the utility model comprises a fixed collar 2 fixedly provided on the outer wall of the filter housing 1, at least two support columns 6 arranged at intervals are fixedly provided on the upper part of the fixed collar 2, and the upper ends of the support columns 6 are fixedly connected to the support plate 7. Generally, two to four support columns 6 are evenly spaced.

[0030] The working principle of the utility model is as follows: first, when in use, the liquor to be filtered is injected through the feed pipe 3, so that the liquor to be filtered enters the upper area of ​​the filter disc 9 in the filter housing 1, and the liquor is filtered through the first filter hole 902 opened on the surface of the filter disc 9, so that the internal particulate impurities are blocked in the upper area of ​​the filter disc 9, and the servo motor 8 fixedly connected to the top of the support plate 7 is turned on, so that the servo motor 8 drives the anti-blocking shaft 10, and then the anti-blocking shaft 10 stirs the particulate impurities in the upper area of ​​the filter disc 9, preventing the particulate impurities from blocking the first filter hole 902. The filter disc 9 is blocked, and is unable to filter out the liquor. At this time, the anti-blocking rotating shaft 10 is driven by the servo motor 8, so that the guide blades 1002 on the surface of the transmission shaft 1001 drive the particulate impurities in the upper area of ​​the filter disc 9 to transport them upward, and the second filter holes 1003 on the surface of the guide blades 1002 filter out the liquor on the surface of the particulate impurities. The transported particulate impurities are then transported into the inner cavity of the storage disc 4 by the guide blades 1002, and then discharged from the storage disc 4 through the slag chute 5 set on one side of the storage disc 4, so as to facilitate the recycling of the particulate impurities and avoid food waste.
