Description

Technical Field

[0001] The utility model relates to the technical field of beet sugar-making equipment, and specifically relates to a filtering device for beet sugar-making. Background Art

[0002] Beet sugar-making is a process that uses beets as raw materials to produce sucrose products through a series of processes. Before processing, beets need to go through pre-treatment steps such as transportation, impurity removal, and washing to remove the soil, dust, and impurities on the surface. Subsequently, the washed beets are sent into a slicer by a bucket elevator or a belt conveyor and cut into uniform beet slices for subsequent sugar extraction. The pre-treated beet slices enter the juice extraction stage, in which hot water is used to extract sugar from the beets to make the original juice. During the juice extraction process, it is required to extract the sugar in the beet slices to the maximum extent with a certain amount of water, and at the same time, try to retain the non-sugars in the waste pulp. Subsequently, based on the original juice, cleaning treatments such as filtration are carried out to remove the impurities therein and improve the purity of the sugar solution. Since the beet pulp waste contains 93% water and about 7% dry matter, it is an ideal feed for animal husbandry such as pig and cattle farming. However, the currently used filtering devices all adopt a method of filtering the waste pulp and impurities at one time. When the output is too large, this filtering method has problems such as high cleaning requirements, easy blockage, and unsatisfactory filtering effect. Moreover, filtering out the sundries in the original juice at one time is also not conducive to the subsequent utilization of the beet pulp waste. Therefore, in view of this situation, certain improvements are needed. Content of the Utility Model

[0003] In view of the above technical problems, the utility model provides a filtering device for beet sugar-making with hierarchical treatment.

[0004] To solve the above technical problems, a filtering device for beet sugar-making according to the utility model includes a tank body. An inlet is provided at the upper part of one side of the tank body. A screw conveyor is fixedly connected to one side of the tank body, and the output end of the screw conveyor corresponds to the position of the inlet. A filtering cylinder is rotatably connected obliquely in the upper part of the tank body, with the feeding end of the filtering cylinder higher than the discharging end, and the feeding end of the filtering cylinder corresponds to the position of the inlet. An outlet is provided at the position of the tank body corresponding to the discharging end of the filtering cylinder. A feeding hopper is fixedly connected to the inlet, and a discharging hopper is fixedly connected to the outlet. A first filter element, a second filter element, and a third filter element are detachably connected in sequence from top to bottom below the filtering cylinder. A liquid outlet is provided at one side of the bottom of the tank body. A first motor is fixedly connected to the tank body, and the filtering cylinder is driven by the first motor. A second motor is fixedly connected to the bottom of the screw conveyor, and the screw conveyor is driven by the second motor.

[0005] Further, a conveyor belt is provided below the outlet.

[0006] Further, the screw conveyor adopts a shaftless screw conveyor.

[0007] Further, cleaning hatches are provided at positions corresponding to the first filter element, the second filter element, and the third filter element on the tank body.

[0008] Further, the mesh number of the sieve holes on the filter cylinder is between 70 and 100 meshes.

[0009] Further, the feed hopper has a U-shaped structure.

[0010] The utility model has the following advantages compared with the prior art:

[0011] Through hierarchical and multiple filtration, the utility model can perform hierarchical filtration according to the characteristics of beet pulp waste and different impurities in the original juice, which can well avoid the situation that the sieve holes are easily blocked; the hierarchical filtration of impurities also facilitates the subsequent recycling of beet pulp waste, avoiding the situation that beet pulp waste and impurities such as stones are mixed together, resulting in difficulties in subsequent processing; by setting an inclined and rotating filter cylinder, the self-weight of the material can be used for discharging and filtering, saving energy while improving the filtration effect.

[0016] The following further describes the utility model with reference to the accompanying drawings.

[0017] As Figures 1 to 3A filtering device for sugar beet sugar production shown in the figure includes a tank body 1. An inlet is provided at the upper part of one side of the tank body 1. A screw conveyor 6 is fixedly connected to one side of the tank body 1, and the output end of the screw conveyor 6 corresponds to the position of the inlet. An upper part inside the tank body 1 is inclined and rotatably connected with a filter cylinder 2 through a bearing. The feeding end of the filter cylinder 2 is higher than the discharging end, and the feeding end of the filter cylinder 2 corresponds to the position of the inlet. A discharging port is provided at the position of the tank body 1 corresponding to the discharging end of the filter cylinder 2. A feeding hopper 8 is fixedly connected at the inlet, and a discharging hopper 9 is fixedly connected at the discharging port. A first filter element 3, a second filter element 4, and a third filter element 5 are detachably connected in sequence from top to bottom below the filter cylinder 2, and the pore diameters of the first filter element 3, the second filter element 4, and the third filter element 5 decrease in sequence. A liquid outlet 12 is provided at one side of the bottom of the tank body 1. A first motor 10 is fixedly connected to the tank body 1, and the filter cylinder 2 is driven by the first motor 10. A second motor 11 is fixedly connected to the bottom of the screw conveyor 6, and the screw conveyor 6 is driven by the second motor 11.

[0018] In order to facilitate the timely transportation and treatment of the sugar beet residue filtered out for the first time, a conveyor belt 7 is provided below the discharging port.

[0019] In order to facilitate the transportation of the mixed material of the original juice and the sugar beet, the screw conveyor 6 adopts a shaftless screw conveyor, which can adapt to the transportation of various materials in different states and can meet the working environments such as vertical transportation.

[0020] In order to facilitate the timely cleaning of impurities on the filter element or the replacement of the filter element, cleaning hatch doors are provided at the positions of the tank body 1 corresponding to the first filter element 3, the second filter element 4, and the third filter element 5.

[0021] In order to meet the requirements of the first filtration, the mesh number of the sieve holes on the filter cylinder 2 is between 70 and 100 meshes.

[0022] In order to facilitate the entry of the original juice and the sugar beet residue into the filter cylinder 2, the feeding hopper 8 has a U-shaped structure.

[0023] The working process of this embodiment is as follows:

[0024] When working, turn on the first motor 10 and the second motor 11. The first motor 10 drives the filter cylinder 2 to rotate, and the second motor 11 drives the auger 6 to rotate. The auger 6 conveys the original juice and beet pulp waste together to the feed hopper 8. Then, through the diversion of the feed hopper 8, the materials are conveyed into the filter cylinder 2. With the continuously rotating filter cylinder 2 and by taking advantage of the self-weight of the materials, the materials will continuously move from the feed end to the discharge end of the filter cylinder 2. During this process, the materials keep turning and contacting the filter cylinder 2 to complete the primary screening. The beet pulp waste is discharged from the discharge hopper 9 and finally conveyed to the subsequent process through the conveyor belt 7. The original juice and fine impurities flow out through the sieve holes on the filter cylinder 2, and then are screened through the different pore sizes of the first filter element 3, the second filter element 4, and the third filter element 5 in sequence. Finally, impurities such as stones and beet shreds are screened out. Finally, the sugar solution flows out from the liquid outlet 12, completing the filtration and screening work of the original juice. When it is necessary to clean the filter element, open the cleaning hatch on the tank body 1, and then the filter element can be cleaned or replaced.
