Description

Technical Field

[0001] The utility model belongs to the technical field of dried fruit processing equipment, and particularly relates to a sewage treatment device for dried fruit production. Background Technique

[0002] Dried fruits are dried fruit pulps made from fresh fruits through methods such as sun drying, drying, and dehydration, which greatly extend the shelf life, have a rich taste, and can be improved with various taste processing techniques such as flavoring. It effectively solves the problem of short fruit preservation period. During the preparation of dried fruits, the fruits need to be cleaned and then sliced. The cleaning mainly focuses on removing dust, fluff, microorganisms, sediment, branches, and withered leaves on the fruit surface.

[0003] Since microorganisms will float on the water surface during the cleaning process, it is not advisable to use the soaking method for cleaning. When the cleaned fruits are fished out through the water surface, microorganisms will attach to the fruit peel again. It is necessary to clean with flowing water to remove microorganisms, and the sewage after cleaning can be reused through filtration. For the sewage after cleaning, segmented filtration is required. The filtered impurities mainly include large impurities such as withered leaves and branches, sediment belongs to medium impurities, while fluff and microorganisms belong to fine impurities. The fine impurities are filtered through a filter membrane or a sponge layer, while the filtration of large and medium impurities will cause the filter holes of the filter membrane to be blocked, affecting the filtration efficiency, and the cost of the filter membrane is higher.

[0004] Therefore, the sewage treatment device prepared by the utility model has a multi-stage filtration structure, which filters impurities separately to improve the filtration efficiency. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0018] Such asFigure 1 As shown in the figure: A sewage treatment device for dried fruit production includes a primary filtration barrel 1 and a secondary filtration barrel 2, both of which are barrel structures with openings on the upper side, and are equipped with detachable end caps to prevent dust from entering. Support frames are installed at the bottoms of the filtration barrels to elevate them. A water inlet pipe 11 is connected to the upper part of the side wall of the primary filtration barrel 1 for introducing sewage, and a drain pipe 21 is connected to the upper part of the side wall of the secondary filtration barrel 2 for discharging the filtered clear water for cleaning water circulation. The primary filtration barrel 1 and the secondary filtration barrel 2 are connected by a connecting pipe 3;

[0019] The primary filtration barrel 1 has a filter screen 4 at the position corresponding to the connection of the water inlet pipe 11. The bottom of the primary filtration barrel 1 is a sedimentation area. The connecting pipe 3 has a first extension pipe 31 extending upward inside the primary filtration barrel 1, with the mouth of the first extension pipe 31 facing upward. The connecting pipe 3 has a second extension pipe 32 inside the secondary filtration barrel 2, and a filter cylinder 5 is sleeved on the second extension pipe 32. Both the first extension pipe and the second extension pipe have their mouths facing upward and have a vertical extension. The mouth of the first extension pipe facing upward is used to prevent the suction of sediment.

[0020] In the present utility model, segmented filtration is carried out through the primary filtration barrel and the secondary filtration barrel. The filter screen is used to block large impurities, such as branches and withered leaves, etc., and can be disassembled for cleaning. The bottom of the primary filtration barrel is a sedimentation area for sedimenting the sediment in the water body. The mouth of the first extension pipe faces upward to prevent the sediment from being lifted by the water flow impact and sucked into the secondary filtration barrel.

[0021] The inside of the secondary filtration barrel is a filter cylinder, and the side wall of the filter cylinder is a filter membrane, which is used to block fine impurities, such as the fluff on the fruit surface, most microorganisms, and the sediment suspended in the water body, etc. The water after cyclic filtration becomes water that can be used for cleaning again.

The inside of the filter screen has a steel structure for support. The steel structure forms a cubic frame structure. The position corresponding to the water inlet pipe is a hollow area, which is used to correspond to the water inlet pipe orifice for filtering large impurities such as branches and withered leaves. After filtering, the impurities inside the filter screen can be cleaned by a detachable method. At the same time, the filter screen can play a buffering role in the incoming water and reduce the water flow rate. The bottom of the primary filter barrel 1 is a conical structure, forming a sedimentation area. The center of the bottom of the primary filter barrel 1 is a discharge port. The position of the discharge port is sealed by a sealing cover. The sedimentation area is used to sediment the sediment in the water body and discharge it through the discharge port.

The discharge pipe 6 is sleeved with a screw pusher and is driven by a motor 61 arranged at the end of the discharge pipe 6. A partition plate 12 is fixed on the central surface of the primary filter barrel 1. The partition plate 12 extends from the opening side of the primary filter barrel 1 to the sedimentation area, and is used to separate the orifices of the first extension pipe 31 and the water inlet pipe 11 into two left and right parts. The area corresponding to the bottom of the partition plate in the sedimentation area is a communication area, which is used to communicate the left and right parts of the first filter barrel and prevent the first extension pipe from sucking in the sewage with sediment.

[0023] The corresponding end orifice of the second extension pipe 32 is sealed. The side wall of the second extension pipe 32 is provided with water permeable holes. The second extension pipe 32 is inserted from the center of the bottom of the secondary filter barrel 2 and extends vertically upward.
