Description

Technical Field

[0001] The utility model belongs to the technical field of flour processing, and particularly relates to a sieve underflow material receiving tank and a purifier. Background Technique

[0002] A purifier is used to separate endosperm particles with different purities from the materials ground by a flour mill. It consists of a sieve body equipped with multiple layers of sieve surfaces, together with an air duct, an air chamber, etc. Each layer of sieve surface is formed by connecting multiple sieve cells equipped with sieve meshes of different mesh numbers in series. When the purifier works, the air flow passes through each layer of sieve surface from the bottom to the top of the sieve body in turn, and then enters the air chamber above the sieve body. The combined action of vibration and air flow can make the materials entering the purifier loose and separate them according to specific gravity, particle shape, surface properties and aerodynamic characteristics. Among them, the light bran is sucked away by the air flow, and the endosperm particles with bran are sent to the flour mill as oversize materials for recycling to remove the endosperm particles with bran. The pure and relatively pure endosperm particles enter the flour mill as undersize materials for further grinding into flour.

[0003] Since the number and distribution positions of the material channels required for different flour mill units and flour milling processes are different, and the current sieve underflow material receiving tank of the purifier is of an integral structure with poor adaptability, for different flour mill units and flour milling process requirements, it is necessary to replace the corresponding sieve underflow material receiving tank as a whole. This not only makes the replacement operation time-consuming and laborious, but also requires a large variety of supporting sieve underflow material receiving tanks, resulting in increased equipment costs and material waste.

[0018] In some embodiments, support plates are respectively connected to both sides of the middle of the middle partition board, and the two support plates are respectively connected to the two side plates.

[0019] Exemplarily, flanging flanges for connecting the screening ship are arranged on the upper boundaries of the two side plates.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] It should be noted that when an element is referred to as being "disposed on" or "connected to" another element, it can be directly on the other element or indirectly on the other element. It should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present application. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or several of such features. In the description of the present application, the meaning of "a plurality" and "several" is two or more, unless otherwise specifically defined.

[0031] Please refer to Figures 1 to 4 , and now the under-screen material receiving trough provided by the present utility model will be described. The under-screen material receiving trough includes a receiving box 10 and two groups of diversion components 20; the receiving box 10 is used for fixedly connecting to the bottom of the screening ship 30 and corresponding to the under-screen material distribution mechanism up and down. The receiving box 10 has two receiving cavities 100, and the two receiving cavities 100 are respectively used for receiving the materials distributed to both sides by the under-screen material distribution mechanism; the two groups of diversion components 20 are respectively detachably connected to the bottoms of the two receiving cavities 100, and at least one discharge pipe 200 is connected to each group of diversion components 20, and each discharge pipe 200 is respectively used for connecting different flour milling units; wherein, the two groups of diversion components 20 are respectively used for receiving the materials falling from the corresponding receiving cavities 100 and guiding the materials to flow to each discharge pipe 200.

[0032] It should be noted that the undersize material distribution mechanism is used to divert the materials falling from the bottom sieve grid. Specifically, it can use distribution plates with different inclination directions to guide the falling materials, so that the materials fall to both sides; the receiving box 10 is provided with two receiving cavities 100 based on the feeding direction of the undersize material distribution mechanism, so that the two receiving cavities 100 can receive equal or unequal amounts of materials as required; on this basis, a set of diversion components 20 are connected to the bottom of each receiving cavity 100, and the bottom of the receiving cavity 100 is open so that the materials entering the receiving cavity 100 can smoothly fall onto the diversion components 20, and then flow to the discharge pipe 200 under the guidance of the diversion components 20. Finally, the discharge pipe 200 transports the materials to the grinding unit. Here, the diversion components 20 can be selected to have a corresponding number of discharge pipes 200 based on the number of grinding units, and the amount of materials required by each grinding unit based on process requirements can be adjusted by adjusting the undersize material distribution mechanism (the orientation of the distribution plate).

[0033] Since the receiving box 10 is fixedly connected to the bottom of the sieve ship 30, it can vibrate together with the sieve ship 30. At the same time, the discharge pipe 200 can be arranged at the low point of the diversion components 20, so as to ensure that the materials falling on the diversion components 20 can flow to the discharge pipe 200 during the vibration process.

[0034] In this embodiment, the diversion components 20 and the receiving box 10 can adopt a detachable connection method of screw connection. The receiving box 10, as a general module, can meet the requirements of different grinding units and flour milling processes for receiving the materials diverted to both sides by the undersize material distribution mechanism. When replacing the grinding unit and the flour milling process, only the corresponding diversion components 20 need to be disassembled and replaced. That is to say, for different grinding units and flour milling process requirements, only the corresponding diversion components 20 need to be configured for spare replacement, without the need to replace the receiving box 10 as a whole, so as to reduce the materials for making the undersize material receiving tank and achieve the purpose of saving material costs and manufacturing costs.

[0035] The undersize material receiving tank provided in this embodiment, compared with the prior art, the receiving box 10 is directly fixed to the bottom of the sieve ship 30 and is divided into two receiving cavities 100 to respectively receive the undersize materials diverted to both sides by the undersize material distribution mechanism. The two sets of diversion components 20 are respectively detachably connected to the bottoms of the two receiving cavities 100 to introduce the materials into the discharge pipe 200; thus, only by replacing the corresponding diversion components 20 can the requirements of different grinding units and flour milling processes be adapted, and the receiving box 10, as a general module, does not need to be disassembled and replaced, thereby improving the adaptability of the undersize material receiving tank and saving the manufacturing materials and costs of the undersize material receiving tank.

[0036] In some embodiments, refer to Figure 1 and Figure 2, the material receiving box 10 includes a middle partition 11, two side boxes 12, and two side plates 13; the two side boxes 12 are symmetric to each other and are respectively connected to both ends of the middle partition 11; the two side plates 13 are symmetrically distributed on both sides of the middle partition 11, and both ends of the side plates 13 are lapped and fixed to the side walls of the two side boxes 12; wherein, the upper edges of the two side plates 13 are both connected to the screening ship 30, and a material receiving cavity 100 is respectively formed between the two side plates 13 and the middle partition 11, and the two side boxes 12 are respectively used to guide the materials falling from above their respective positions into the material receiving cavity 100. The middle partition 11 and the two side plates 13 can form two cavities, namely the material receiving cavity 100. At the same time, the two side boxes 12 are connected to both ends of the side plates 13 to form an integral structure. The side boxes 12 are used to receive the materials falling from both ends of the screening ship 30 and guide the materials to flow towards the middle and enter the material receiving cavity 100. By setting the side boxes 12, not only can the span of the diversion component 20 be reduced, facilitating the disassembly and replacement of the diversion component 20, but also the overall structural strength of the material receiving box 10 can be improved.

[0037] As a specific implementation manner of the above side box 12, please refer to Figure 2 and Figure 3 , the side box 12 includes two boxes 121 respectively fitted and fixed to both sides of the end of the middle partition 11. The bottom surface of the box 121 is an inclined surface suitable for guiding the material to slide into the material receiving cavity 100, and the side plate 13 is lapped and fixed to the side wall of the box 121 away from the middle partition 11. The side box 12 adopts two box bodies 121 with U-shaped groove structures, which are respectively arranged on both sides of the middle partition 11, so that the materials dialed by the under-screen material distribution mechanism to both sides can respectively fall into the two box bodies 121, thereby improving the accuracy of the material input amount in the two material receiving cavities 100.

[0038] In some possible implementation manners, please refer to Figure 2 , the lower boundaries of the two side plates 13 are both horizontally aligned with the lower boundary of the middle partition 11. The lower boundary of the side plate 13 includes a first inclined side 131 and a second inclined side 132 arranged at an angle; the first inclined side 131 and the second inclined side 132 respectively form a material receiving port with the lower boundary of the middle partition 11; wherein, the diversion component 20 includes two deflectors, and the two deflectors are respectively detachably connected to one of the material receiving ports.

[0039] Both the first inclined side 131 and the second inclined side 132 form an inclined material receiving port with a part of the lower boundary of the middle partition 11, so that each material receiving port can correspondingly connect one of the deflectors, and the position of the discharge pipe 200 can be changed by flexibly replacing deflectors with different structures, thereby improving the adaptability.

[0040] For example, please refer to Figure 1 and Figure 3, where one of the fluid guides is the flow guide groove 21. A discharge pipe 200 is provided at the bottom of the flow guide groove 21, and the bottom of the flow guide groove 21 is an inclined surface or a V-shaped surface suitable for guiding the material to flow towards the discharge pipe 200. The other fluid guide is the inclined plate 22, and the inclined plate 22 is used to guide the material to flow towards the flow guide groove 21.

[0041] Correspondingly, the flow guide assembly 20 corresponding to one of the material receiving cavities 100 can be a combined structure of a flow guide groove 21 and an inclined plate 22. The inclined plate 22 blocks one of the material receiving ports along the first inclined side 131 or the second inclined side 132 to form an inclined surface suitable for the material to flow. The flow guide groove 21 receives the material flowing down along the slope and converges the material in the flow guide groove 21 into the discharge pipe 200 connected to the lowest position of the flow guide groove 21, so as to realize that all the materials falling into the same material receiving cavity 100 are discharged by the same discharge pipe 200. Moreover, by exchanging the positions of the inclined plate 22 and the flow guide groove 21, the position of the discharge pipe 200 can also be changed. At the same time, based on whether the bottom of the flow guide groove 21 is a full inclined surface structure or a V-shaped surface structure, the position of the discharge pipe 200 can also be changed, thereby improving the adaptability to different grinding mill units and flour milling process requirements.

[0042] Exemplarily, as Figure 1 and Figure 3 shown, both of the fluid guides are the flow guide grooves 21 provided with discharge pipes 200 at the bottom, and a baffle 23 is provided between the two flow guide grooves 21. The baffle 23 extends upward into the material receiving cavity 100. For the method of arranging two discharge pipes 200 to deliver materials to different units of the grinding mill for the same material receiving cavity 100, two flow guide grooves 21 are used as the two fluid guides of the flow guide assembly 20, and the two flow guide grooves 21 are separated by the baffle 23. Thus, the materials entering the same material receiving cavity 100 can be separated into two parts and discharged into the two flow guide grooves 21 respectively, and are respectively converged into the discharge pipes 200 connected to their respective lowest positions in the flow guide grooves 21 and then enter different grinding units. Here, the position of the discharge pipe 200 can be changed based on whether the bottom structure of the flow guide groove 21 is a full inclined surface or a V-shaped surface, so that the adaptability requirements of different grinding mill units and flour milling process requirements can be met by replacing the corresponding flow guide groove 21.

[0043] Since the span of the material receiving box 10 is relatively large, in order to improve the structural strength of the material receiving cavity 100 and prevent the side plates 13 from being recessed inward or bulged outward, please refer to Figure 3 , on both sides of the middle of the middle partition plate 11, support plates 24 are respectively connected, and the two support plates 24 are respectively connected to the two side plates 13.

[0044] It should be noted that, as Figure 2As shown, flanging flanges 133 for connecting the screening ship 30 are provided at the upper boundaries of the two side plates 13. By providing the flanging flanges 133, on the one hand, the structural strength of the side plates 13 can be improved, and on the other hand, it is convenient to connect and fix to the bottom of the screening ship 30.

[0045] In some embodiments, please refer to Figure 3 , the two side walls of the side box 12 extend upward into the interior of the screening ship 30 and fit against the inner wall of the screening ship 30. The top of the side wall of the side box 12 is higher than the side plate 13. Thus, after the receiving box 10 is fixed to the screening ship 30, a structure is formed in which the top of the side box 12 extends into the interior of the screening ship 30, and the connection sealing performance and reliability are improved by fitting the side box 12 against the interior of the screening ship 30.

[0046] Based on the same inventive concept, in combination with Figures 1 to 4 it is understood that the embodiment of the present application further provides a purifier including the above-mentioned undersize receiving trough.

[0047] Compared with the prior art, the purifier provided in this embodiment adopts the above-mentioned undersize receiving trough. The receiving box 10 is directly fixed to the bottom of the screening ship 30 and divided into two receiving cavities 100 to respectively receive the undersize materials distributed to both sides by the undersize distributing mechanism. The two groups of guiding components 20 are respectively detachably connected to the bottoms of the two receiving cavities 100 to introduce the materials into the discharge pipe 200. Therefore, only by replacing the corresponding guiding components 20 can the requirements of different flour milling units and flour making processes be adapted. The receiving box 10, as a general module, does not need to be disassembled and replaced, thereby improving the adaptability of the undersize receiving trough and saving the production materials and costs of the undersize receiving trough.

[0048] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
