Description

Technical Field

[0001] The invention relates to the technical field of sediment transfer, in particular to a river sediment screw conveyor with a screening function. Background Art

[0002] With the continuous development of social economy and people's high attention to environmental protection, the importance of river cleaning has become increasingly prominent. In the current river cleaning practice, screw conveyors are often used to transport mud, water and sand mixtures in the river; however, the existing screw conveyors have obvious shortcomings in river cleaning applications.

[0003] First of all, the existing screw conveyors are only limited to the conveying function when cleaning the river channel, and are unable to effectively screen the mud, water and sand mixture during the conveying process; the mud and sand in the river channel have different shapes and types, covering mud, water, fine sand, medium-coarse sand, gravel, pebbles and other types; mud and sand of different particle sizes have very different uses. If they cannot be screened efficiently, it is difficult to achieve the rational use of resources; for example, fine sand has broad application prospects in the construction field and can be used as a high-quality building material; however, the unscreened mixture cannot be used directly in construction and must undergo a series of tedious subsequent screening operations; this undoubtedly greatly increases the steps of the work and consumes more time costs.

[0004] Not only that, the subsequent screening work will also require more manpower, material resources and equipment, further increasing the cost of river cleaning; at the same time, there will be significant consumption of material resources; for example, additional sites are needed to place screening equipment and temporarily store the mud, water and sand mixture to be screened, and the rental or use of these sites will cost a certain amount of money. In addition, a large amount of energy is required to drive the screening equipment, such as electricity, fuel, etc. In terms of equipment, it is necessary to purchase special screening machines, and maintenance and maintenance are required during use, which further increases the cost investment.

[0005] Therefore, the present invention proposes a river sediment screw conveyor with screening function to solve the above problems. Summary of the invention

[0006] In view of this, the technical problem to be solved by the present invention is to propose a river sediment screw conveyor with a screening function to solve the problems existing in the prior art.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a river sediment screw conveyor with a screening function, comprising: a conveyor body, an auxiliary plate, and a square frame shell, wherein the conveyor body, the auxiliary plate, and the square frame shell are in the same horizontal plane, and also comprising: a particle size judgment component and a screening and collecting adjustment component, wherein the screening and collecting adjustment component is located in the middle of the particle size judgment component; the particle size judgment component is used to judge the proportion of sand particles of different particle sizes in the water flow; the screening and collecting adjustment component is used to adjust the collection method according to the proportion of different sand particles judged by the particle size judgment component.

[0009] Preferably, a partition plate is fixedly connected to the first screening cavity, a transfer opening is penetrated through the side end face of the first screening cavity, the end face of the first screening cavity is rotatably connected to a storage ring body through a column shaft, the first screening cavity and the storage ring body fit well, a counterweight block is fixedly connected to the bottom of the storage ring body, and a gravity sensor is fixedly connected to the inner arc surface of the storage ring body.

[0010] Preferably, the screening, collecting and adjusting assembly comprises a parts bin fixedly connected in a square frame shell, a guide body is vertically slidably connected to the parts bin, and a baffle is fixedly connected to an inner cavity wall of the square frame shell.

[0011] Preferably, a collecting bin body is provided on one side of the flow guide body, collecting holes are equidistantly provided on the collecting bin body, a transfer pipe belt is fixedly connected to the bottom of the collecting hole, an electric telescopic rod is fixedly connected to the bottom of the collecting bin body, and a rotating wheel is rotatably connected to the bottom of the electric telescopic rod.

[0012] Preferably, a support frame is fixedly connected to the inner cavity of the parts bin, a rotating shaft B is rotatably connected to the support frame, a disc is fixedly connected to the rotating shaft B, and the rotating shaft B is inserted into the eccentric part of the disc.

[0013] Preferably, a drainage hole is provided on the storage ring body.

[0014] Preferably, the collecting bin body, collecting hole, transfer tube belt, electric telescopic rod, rotating wheel and supporting frame form a group, namely, a particle size collection group.

[0015] Compared with the prior art, the present invention provides a river sediment screw conveyor with screening function, which has the following beneficial effects: 1. The present invention adopts the design of particle size judgment components, and samples are taken when the conveyor body transports the sediment mixture, and the operation of judging the proportion of sand particles of different particle sizes in the total sand particles during sampling has the following advantages: First: Optimize the subsequent processing flow; the particle size proportion information obtained by sampling provides an important basis for subsequent screening and processing work; the parameters and working mode of the screening equipment can be adjusted according to the proportion situation, so that the screening process is more efficient and accurate; for example, if the proportion of coarse sand is large, the equipment can be adjusted in time to increase the processing speed, which is helpful to plan the subsequent processing steps in advance and reduce unnecessary operations and equipment investment.

[0016] Second: Improve the efficiency of river cleaning work; sampling and analysis can be carried out without stopping the conveying work of the conveyor body, which will not affect the overall progress of river cleaning; compared with the traditional method of conveying first and then analyzing separately, it greatly saves time and improves work efficiency; it can provide real-time data support for river cleaning work in a timely manner, so that operators can adjust work strategies in time according to changes in proportion, ensuring that the cleaning work is always carried out efficiently.

[0017] Third: Improve resource utilization efficiency; by taking samples during the transportation process and determining the proportion of sand particles of different particle sizes, we can more accurately understand the composition of river sediment. Based on the proportion information, we can carry out targeted resource utilization planning and apply sand particles of different particle sizes to appropriate fields, greatly improving resource utilization efficiency.

[0018] 2. The present invention can effectively improve the accuracy and efficiency of screening through the design of the screening, collecting and adjusting components; it can make adaptive adjustments according to the sand particles of different particle sizes in the mud and water, and can realize the precise screening of sand particles of different particle sizes, and can better adapt to the actual composition of the mud and sand mixture, and avoid the problem of incomplete screening or over-screening of some sand particles due to fixed screening settings, thereby improving the accuracy and efficiency of screening.

[0019] In addition, the adaptability and flexibility of the equipment are enhanced; the design enables the conveyor body to adapt to the sediment mixture conditions in different river channels or at different stages; in different river channel environments, there are large differences in the particle size distribution of sediment, and this adaptability adjustment function can ensure that the equipment can effectively perform screening work under various conditions, thereby improving the adaptability and flexibility of the equipment; whether in a river channel with more medium and coarse sand or in a river channel with more fine sand, the equipment can achieve better screening effects through adaptability adjustment, reducing the possibility of replacing equipment or making large-scale modifications to the equipment due to changes in sediment characteristics.

[0020] 3. The present invention can effectively improve the accuracy of particle size judgment through the arc-shaped design of the perforated focusing plate; specifically, the arc-shaped design of the perforated focusing plate can detain the mud, water and sand mixture, which allows mud and sand of different particle sizes to be collected in a relatively stable environment, avoiding the problem of inaccurate particle size judgment caused by the rapid flow of mud and sand; through the above-mentioned method, the proportion information of sand particles of different particle sizes can be obtained more accurately, providing reliable data support for subsequent screening and processing work; for example, in actual applications, when the mixture flows rapidly, fine sand may be entrained by coarse sand, and it is difficult to accurately judge its true proportion, and the design of the perforated focusing plate can effectively avoid this situation and improve the accuracy of particle size judgment.

[0021] 4. The present invention uses two adjacent collecting bins. In the case of inconsistent heights, the relatively high collecting bin will be used as a barrier to block the flow of the mud, water and sand mixture, so that the flow of the mud, water and sand mixture is blocked. This flow obstruction and the impact and backflow action are more conducive to the sand entering the inner cavity of the collecting bin through the collection hole; the sand collection efficiency can be improved. Compared with the case without such a design, the sand collection process is more orderly and efficient, reducing the loss of sand during the collection process and improving the collection rate of sand; for example, in actual applications, if there is no such blocking and impact backflow design, the sand may flow through the collection area quickly with the mixture, resulting in incomplete collection. With the above design, more sand can be effectively collected.

[0022] At the same time, the controllability of the collection process is enhanced; by setting up two adjacent collection bins and using their height difference to control the flow of the mixture and the collection of sand, the entire collection process is more controllable; the operator can adjust the height difference of the collection bins according to actual needs to adapt to mixtures of different sediment compositions and different working requirements; this controllability improves the adaptability of the equipment to different working conditions and ensures that sand can be effectively collected under various circumstances.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0038] Example: Please refer to Figures 1 to 7As shown: In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a river sediment screw conveyor with a screening function, including: a conveyor body 1, an auxiliary plate 2, and a square frame shell 3. The conveyor body 1, the auxiliary plate 2, and the square frame shell 3 are in the same horizontal plane, and also include: a particle size judgment component 4, a screening and collecting adjustment component 5, and the screening and collecting adjustment component 5 is located in the middle of the particle size judgment component 4.

[0039] The particle size judgment component 4 is used to judge the proportion of sand particles of different particle sizes in the water flow; the particle size judgment component 4 includes a perforated flow collecting plate 401 fixed to the inner wall of the square frame shell 3, a rotating shaft A402 is fixedly connected to the middle of the inner wall of the square frame shell 3, a connecting rod 403 is fixedly connected to the rotating shaft A402, one end of the perforated flow collecting plate 401 is fixedly connected to a first screening cavity 404, and the other end of the perforated flow collecting plate 401 is fixedly connected to a second screening cavity, and the first screening cavity 404 Screening holes 405 are fixedly connected at equal intervals on the upper surface, a partition plate 406 is fixedly connected inside the first screening cavity 404, a transfer port 407 is penetrated through the side end surface of the first screening cavity 404, a storage ring body 408 is rotatably connected to the end surface of the first screening cavity 404 through a column shaft, the first screening cavity 404 and the storage ring body 408 fit well, a counterweight block 409 is fixedly connected to the bottom of the storage ring body 408, and a gravity sensor 410 is fixedly connected to the inner arc surface of the storage ring body 408.

[0040] Among them: the particle size determination component 4 is mainly used to determine the proportion of sand particles of different particle sizes in the water flow.

[0041] The arc ring design of the perforated flow collecting plate 401 is mainly used to detain the mud, water and sand mixture transported from the conveyor body 1, so as to facilitate the collection of different particle sizes in the mud and sand and assist in the operation of determining the proportion of different particle sizes. An electric blocking piece is provided at one end of the perforated flow collecting plate 401, which is mainly used to block the opening of the perforated flow collecting plate 401 facing the conveyor body 1 when determining the particle size.

[0042] The screening hole 405 is mainly used for sand particles smaller than its own particle size to enter and be transferred through the partition plate 406.

[0043] The partition plate 406 is mainly used to transfer the sand particles entering the first screening chamber 404 .

[0044] The transfer port 407 is mainly used to transfer the sand in the first screening cavity 404 to the storage circle 408 .

[0045] The storage ring body 408 is provided with a drainage hole.

[0046] When the gravity sensor 410 performs gravity measurement, the connecting rod 403 needs to be adjusted to a horizontal level through the rotating shaft A402, so that the excess water except the sand transferred into the receiving ring 408 can be transferred out through the drain hole on the receiving ring 408. The screening hole 405, the partition plate 406, the transfer port 407, the receiving ring 408, the counterweight block 409, and the gravity sensor 410 form a group, namely, a particle size weight feedback group.

[0047] Another set of particle size weight feedback groups is arranged in the second screening chamber, the only difference being that the aperture of the screening holes 405 therein is different from that of the previous set.

[0048] For further examples, please refer to Figure 1 , Figure 2 , Figures 7 to 10 As shown: the screening and collecting adjustment component 5 is used to adjust the collection method according to the proportion of different sand particles determined by the particle size judgment component 4. The screening and collecting adjustment component 5 includes a parts bin 501 fixedly connected in the square frame shell 3, a guide body 502 is vertically slidably connected to the parts bin 501, a baffle plate 503 is fixedly connected to the inner cavity wall of the square frame shell 3, a collecting bin body 504 is arranged on one side of the guide body 502, collecting holes 505 are equidistantly provided on the collecting bin body 504, a transfer pipe belt 506 is fixedly connected to the bottom of the collecting hole 505, an electric telescopic rod 507 is fixedly connected to the bottom of the collecting bin body 504, a rotating wheel 508 is rotatably connected to the bottom of the electric telescopic rod 507, a supporting frame is fixedly connected to the inner cavity of the parts bin 501, a rotating shaft B510 is rotatably connected to the supporting frame, a disc 511 is fixedly connected to the rotating shaft B510, and the rotating shaft B510 is plugged into the eccentric center of the disc 511.

[0049] Among them: the screening collection adjustment component 5 is mainly used to adjust the collection method according to the proportion of different sand particles determined by the particle size determination component 4.

[0050] The shielding plate 503 is mainly used to prevent the mud, water and sand mixture from being transferred away without being screened.

[0051] When two adjacent collecting bins 504 are of inconsistent heights, the relatively higher collecting bin 504 will be used as a barrier to block the flow of the mud, water and sand mixture, thereby obstructing the flow of the mud, water and sand mixture and causing it to surge back after impact, making it easier for the sand in the mud, water and sand mixture to enter the inner cavity of the collecting bin 504 through the collecting hole 505.

[0052] The electric telescopic rod 507 is electrically connected to the gravity sensor 410 through the main controller of the device.

[0053] The collecting bin body 504, the collecting hole 505, the transfer tube belt 506, the electric telescopic rod 507, the rotating wheel 508 and the supporting frame form a group, namely, a particle size collecting group; multiple groups can be provided according to specific circumstances, the only difference being that the aperture of the collecting hole 505 is different.

[0054] The disc 511 is mainly used in conjunction with the rotating wheel 508 .

[0055] The working principles of all the contents in the above embodiments are as follows: It should be noted that the device is mainly used in usage scenarios such as river banks where there are mostly sand particles of varying sizes.

[0056] The following is the working process of the particle size judgment component 4: After the screw conveying equipment is set up on the bank of the river with mud, water and sand mixture, the conveyor body 1 can convey the mud, water and sand mixture entering the shell from low to high through the screw conveying blades.

[0057] During the conveying process, the mud, water and sand mixture being conveyed will be in the lower middle part of the inner cavity of the conveyor body 1, and the mud, water and sand mixture conveyed by the spiral conveying blades in the conveyor body 1 will be further conveyed to the square frame shell 3. For further information, please refer to the attached Figure 2 And attached Figure 3 As the mud, water and sand mixture enters, the mud, water and sand mixture will move along the inner arc surface of the perforated focusing plate 401 under the obstruction of the perforated focusing plate 401, so that the mud, water and sand mixture will be detained for a certain period of time. During this process, the rotating shaft A402 will rotate with the first screening cavity 404 and the second screening cavity with different particle size holes at both ends through the connecting rod 403 around the rotating shaft A402. During the detention of the mud, water and sand mixture, sand particles of different particle sizes in the mud, water and sand mixture will enter through the rotating first screening cavity 404 and the sieve holes opened on the screening hole 405. Specifically, taking the first screening cavity 404 as an example, when the first screening cavity 404 rotates with the rotating shaft A402 as the rotating axis, the sand particles smaller than the aperture size of the screening hole 405 in the mud, water and sand mixture detained by the perforated focusing plate 401 will enter the first screening cavity 404; for further information, please refer to the attached Figure 5 And attached Figure 6When the sand enters the first screening chamber 404, first, the sand will be distributed on both sides of the partition plate 406. However, due to the arc-shaped guidance, as the first screening chamber 404 rotates with the rotation axis A402 as the axis, the sand on one side of the partition plate 406, that is, the sand on the side where the non-transfer port 407 is located, will eventually follow the arc surface to enter the side where the transfer port 407 is located, and finally enter the storage ring body 408 on one side of the first screening chamber 404 through the transfer port 407. It should be noted that since a counterweight block 409 is provided at the bottom of the storage ring body 408, the storage ring body 408 is always in the state where the first screening chamber 404 rotates with the rotation axis A402 as the rotation center. In an unchanged state, further, after a certain unit time has passed since the device was started and the sand entered into the receiving circle 408, the particle size determination work can begin; when the gravity sensor 410 performs gravity measurement, the connecting rod 403 needs to be adjusted to a horizontal level through the rotating shaft A402, so as to transfer the excess water except the sand into the first screening cavity 404 and the second screening cavity through the drainage hole on the receiving circle 408. After the above steps are completed, the two gravity sensors 410 in the receiving circle 408 and the second screening cavity will weigh the sand to determine the proportion of sand of different particle sizes in the river, so as to adjust the screening collection adjustment component 5 through feedback.

[0058] Furthermore, through the design of the particle size judgment component 4, sampling is performed when the conveyor body 1 transports the mud and sand mixture, and the proportion of sand particles of different particle sizes in the total sand particles is judged during sampling, which can optimize the subsequent processing process; the particle size proportion information obtained by sampling provides an important basis for subsequent screening and processing work; the parameters and working mode of the screening equipment can be adjusted according to the proportion, making the screening process more efficient and accurate; for example, if the proportion of coarse sand is large, the equipment can be adjusted in time to increase the processing speed, which helps to plan subsequent processing steps in advance and reduce unnecessary operations and equipment investment.

[0059] It can improve the efficiency of river cleaning work; sampling and analysis can be carried out without stopping the conveying work of the conveyor body 1, and will not affect the overall progress of river cleaning; compared with the traditional method of first conveying and then analyzing separately, it greatly saves time and improves work efficiency; it can provide real-time data support for river cleaning work in a timely manner, so that operators can adjust work strategies in time according to changes in proportion, ensuring that the cleaning work is always carried out efficiently.

[0060] Improve resource utilization efficiency; by taking samples during the transportation process and determining the proportion of sand particles of different particle sizes, we can more accurately understand the composition of river sediment. Based on the proportion information, we can carry out targeted resource utilization planning and apply sand particles of different particle sizes to appropriate fields, greatly improving resource utilization efficiency.

[0061] Furthermore, the arc-shaped design of the perforated focusing plate 401 can effectively improve the accuracy of particle size judgment; specifically, the arc-shaped design of the perforated focusing plate 401 can detain the mud, water and sand mixture, which allows mud and sand of different particle sizes to be collected in a relatively stable environment, avoiding the problem of inaccurate particle size judgment caused by the rapid flow of mud and sand; through the above method, the proportion information of sand particles of different particle sizes can be obtained more accurately, providing reliable data support for subsequent screening and processing work; for example, in actual applications, when the mixture flows rapidly, fine sand may be entrained by coarse sand, and it is difficult to accurately judge its true proportion, and the design of the perforated focusing plate 401 can effectively avoid this situation and improve the accuracy of particle size judgment.

[0062] Please refer to the above working process Figures 1 to 7 .

[0063] The following is the working process of the screening collection adjustment component 5: Further, after the particle size judgment component 4 makes a particle size ratio judgment, the device master controller will adjust the extension distance of the electric telescopic rod 507, thereby indirectly adjusting the height of the collection bin 504, which can be referred to in the attached Fig.10 And attached Figure 8 As it is known that the collecting bin body 504, the collecting hole 505, the transfer tube belt 506, the electric telescopic rod 507, the rotating wheel 508 and the supporting frame are a group, namely the particle size collecting group; multiple groups can be arranged according to the specific situation. The only difference is that the aperture of the collecting hole 505 is different. Another group of collecting bin bodies 504 and the guide body 502 adjacent to the collecting bin body 504 are also controlled by a telescopic rod similar to the electric telescopic rod 507 to adjust the height.

[0064] Furthermore, after the initial heights of the adjacent guide bodies 502 and the collecting bin bodies 504 are adjusted, the device can enter a stage where it can efficiently screen and collect the proportions of sand particles of different particle sizes in the mud, water and sand mixture.

[0065] Furthermore, the disc 511 eccentrically fixed on the rotating shaft B510 will push the rotating wheel 508 during the rotation of the rotating shaft B510, so that the electric telescopic rod 507 with adjusted length thereon will move the collecting bin 504 upward. Furthermore, since the disc 511 is eccentrically fixed on the rotating shaft B510, as the disc 511 rotates, the rotating wheel 508 that contacts the disc 511 will move the collecting bin 504 on the electric telescopic rod 507 downward. Similarly, the disc 511 eccentrically fixed on the rotating shaft B510 will also move the guide body 502 and the collecting bin 504 up and down respectively through a telescopic rod similar to the electric telescopic rod 507. It is known that the eccentric positions of the adjacent discs 511 are fixed at different positions, and reference can be made to the attached figure. Fig. 9Thus, the guide body 502 and the collection chamber body 504 will be in a state of alternating up and down movement.

[0066] For further information, please refer to the attached Figure 7 When the mud, water and sand mixture moves toward the direction where the guide body 502 and the plurality of collecting bins 504 are located, the guide body 502 and the collecting bins 504 that move alternately up and down will hinder the flow.

[0067] Furthermore, through the flow diversion of the diversion body 502 and the two adjacent collection bins 504, in the case of inconsistent heights, the relatively high collection bin 504 will be used as a barrier to block the flow of the mud, water and sand mixture, so that the flow of the mud, water and sand mixture is blocked. This flow obstruction and the impact and backflow action are more conducive to the sand entering the inner cavity of the collection bin 504 through the collection hole 505 and being transferred by the transfer pipe 506; the sand collection efficiency can be improved. Compared with the case without such a design, the sand collection process is more orderly and efficient, reducing the loss of sand during the collection process and improving the collection rate of sand; for example, in actual applications, if there is no such blocking and impact backflow design, the sand may flow through the collection area quickly with the mixture, resulting in incomplete collection. With the above design, more sand can be effectively collected.

[0068] At the same time, the controllability of the collection process is enhanced; by setting two adjacent collection bins 504 and using their height difference to control the flow of the mixture and the collection of sand, the entire collection process is made more controllable; the operator can adjust the height difference of the collection bins 504 according to actual needs to adapt to mixtures of different sediment compositions and different working requirements; this controllability improves the adaptability of the equipment to different working conditions, ensuring that sand can be effectively collected under various circumstances.

[0069] Furthermore, through the design of the screening, collecting and adjusting component 5, the screening accuracy and efficiency can be effectively improved; it can be adaptively adjusted according to the sand particles of different particle sizes in the mud and water, and can realize the precise screening of sand particles of different particle sizes, which can better adapt to the actual composition of the mud and sand mixture, and avoid the problem of incomplete screening or over-screening of some sand particles due to fixed screening settings, thereby improving the screening accuracy and efficiency.

[0070] Moreover, the adaptability and flexibility of the equipment are enhanced; this design enables the conveyor body 1 to adapt to the sediment mixture conditions in different river channels or at different stages; in different river channel environments, there are large differences in the particle size distribution of sediment, and this adaptability adjustment function can ensure that the equipment can effectively perform screening work under various conditions, thereby improving the adaptability and flexibility of the equipment; whether in a river channel with more medium-coarse sand or in a river channel with more fine sand, the equipment can achieve better screening effects through adaptability adjustment, thereby reducing the possibility of replacing equipment or making large-scale modifications to the equipment due to changes in sediment characteristics.
