Description

Technical Field

[0001] The invention belongs to the field of material separation devices, and in particular relates to a precipitation separation device. Background Art

[0002] At present, as the concept of energy conservation and environmental protection gradually takes root in people's minds, the field of waste recycling is receiving increasing attention; since electrical appliances in daily life contain a large number of plastic products, and most of these plastic products are mixed with other materials, separation requires certain processes and procedures.

[0003] Currently, sedimentation separation devices are commonly used to separate and recycle plastic mixtures from old electrical appliances. Separation liquid is first injected into the separation sedimentation tank, and the mixed material is then placed into the separation liquid. Finally, the floating and sinking materials are separated and recycled through their respective collection devices. However, due to the problem that some plastic mixtures may be tightly connected, the floating and sinking materials cannot be separated after a brief contact with the separation liquid. As a result, the floating materials and the sinking materials sink to the bottom together and are discharged from the sinking material outlet, failing to fully separate the floating and sinking materials. Summary of the Invention

[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide a sedimentation separation device which can separate floating material and sinking material more fully and achieve better separation effect.

[0005] The purpose of the present invention is achieved by adopting the following technical solutions:

[0006] A sedimentation separation device comprising:

[0007] The shell is provided with a receiving cavity for receiving the separation liquid, a floating material outlet, and a sinking material outlet. The bottom of the shell is a multi-step structure.

[0009] A plurality of sinking material discharging devices are arranged one by one on each level of the multi-level stepped structure, and are used to transport the sinking material upward step by step along the multi-level stepped structure and discharge it from the sinking material outlet.

[0010] Furthermore, a placement groove is provided at the bottom of the multi-step stepped structure corresponding to the sinking material discharge device.

[0011] Furthermore, the shell is provided with an inclined surface for guiding the sediment to the placement groove.

[0012] Furthermore, the shell is provided with a discharge channel adapted to the sinking material discharge device.

[0013] Furthermore, the floating material outlet and the sinking material outlet are both arranged at a height on the shell that is higher than the height of the separation liquid that can be accommodated in the shell.

[0014] Furthermore, it also includes a material distribution device for dispersing the plastic mixture, and the material distribution device is arranged in the accommodating cavity.

[0015] Furthermore, the material dividing device is a material dividing roller and a material dividing driver for driving the material dividing roller to move, and a plurality of material dividing sheets are provided on the side wall of the material dividing roller.

[0016] Furthermore, it also includes a cleaning device for cleaning floating materials, and the cleaning device is arranged on the upper layer of the accommodating cavity.

[0017] Furthermore, the cleaning device comprises a plurality of cleaning rollers and a cleaning driver for driving all the cleaning rollers to move, and a plurality of cleaning paddles are provided on the side walls of the cleaning rollers.

[0018] Furthermore, the floating material discharge device includes a chain conveying assembly, a plurality of toggling members arranged on the chain conveying assembly, and a toggling driver for driving the chain conveying assembly to move, and a plurality of scraping claws are arranged at intervals on the toggling member.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] When the sedimentation separation device of the present invention is in use, the staff can first pour the separation liquid into the housing cavity of the shell until it fills most of the housing cavity, and then pour the plastic mixture into the separation liquid. At this time, the plastic mixture will be separated into floating material and sinking material after contacting the separation liquid. The separated floating material will be discharged from the floating material outlet under the action of the floating material discharge device, while the sinking material will sink to the bottom of the shell due to its own weight, and will be transported step by step along each step structure under the action of multiple sinking material discharge devices. At the same time, when each two steps are connected, the sinking material will be separated due to the height difference and the action of the two discharge devices, so that the floating material mixed in the sinking material is separated, and finally the sinking material is discharged from the sinking material outlet. This solution uses the multi-stage stepped structure and the setting of multiple sinking material discharge devices to enable the sinking material to be stirred multiple times, and ultimately the sinking material and floating material of the plastic mixture are separated more thoroughly, thereby improving the accuracy of subsequent processes.

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] The present invention refers to Figure 1-Figure 2As shown, it includes a shell 10, a floating material discharge device 20 and a plurality of sinking material discharge devices 30. The shell 10 is provided with a accommodating chamber for accommodating the separation liquid, a floating material outlet 101 and a sinking material outlet 102. The bottom of the shell 10 is a multi-step stepped structure 103. Each step of the multi-step stepped structure 103 is inclined upward and the starting end height of the next step is lower than the end height of the previous step. The floating material discharge device 20 is used to discharge the floating material from the floating material outlet 101. The plurality of sinking material discharge devices 30 are arranged one by one on each step of the multi-step stepped structure 103, and are used to transport the sinking material upward step by step along the multi-step stepped structure 103 and discharge it from the sinking material outlet 102. When this solution is in use, the staff can first pour the separation liquid into the accommodating cavity of the shell 10 until it fills most of the accommodating cavity, and then pour the plastic mixture into the separation liquid. At this time, the plastic mixture will be separated into floating material and sinking material after contacting the separation liquid. The separated floating material will be discharged from the floating material outlet 101 under the action of the floating material discharge device 20, while the sinking material will sink to the bottom of the shell 10 due to its own weight and be transported step by step along each step structure under the action of multiple sinking material discharge devices 30. At the same time, when each two steps are connected, the sinking material will be separated due to the height difference and under the action of the two discharge devices, so that the floating material mixed in the sinking material is separated, and finally the sinking material is discharged from the sinking material outlet 102. Through the arrangement of the multi-stage stepped structure 103 and the multiple sinking material discharge devices 30, the sinking material can be stirred multiple times, and finally the sinking material and floating material of the plastic mixture are separated more thoroughly, thereby improving the accuracy of the subsequent process.

[0031] As a preferred embodiment of the present invention, it may also have the following additional technical features:

[0032] In this embodiment, refer to Figure 3 As shown, the bottom of the multi-step ladder structure 103 is provided with a placement groove 1031 corresponding to the sinking material discharge device 30. Through this arrangement, firstly, the sinking material discharge device 30 is stably installed and fixed in the placement trough body, and at the same time, the sinking material sunk at the bottom of the shell 10 can slowly fall into the placement trough body, and finally be transported under the action of the sinking material discharge device 30, and the sinking material transportation effect is better. Specifically, the sinking material discharge device 30 is a spiral conveying device, and the placement groove 1031 is a strip-shaped arc groove. In other embodiments, the shape of the placement groove 1031 is mainly designed to correspond to the structure of the sinking material discharge device 30. For example, when the sinking material discharge device 30 is a cylinder push rod, the placement trough body is designed to correspond to the shape of the push rod, and is not limited to the above-mentioned implementation method.

[0033] Reference Figure 3As shown, in combination with the design of the placement groove 1031 described above, the housing 10 is provided with an inclined surface 104 for guiding the sediment into the placement groove 1031. The provision of the inclined surface 104 allows the sediment to gradually slide along the inclined surface 104 into the placement groove 1031 after the plastic mixture is separated, thereby preventing the sediment from being scattered at the bottom of the housing 10 without being transported out. Specifically, the four side surfaces of the housing 10 are provided with inclined surfaces 104, so that the sediment separated at each position will contact the inclined surface 104 on the side surface and be guided into the placement groove 1031, and finally be transported out by the sediment discharge device 30.

[0034] In this embodiment, refer to Figure 1-Figure 2 As shown, the housing 10 is provided with a discharge channel 105 adapted to the sinking material discharge device 30. By providing the discharge channel 105, the space of the discharge channel 105 can be adapted to the size of the sinking material discharge device 30. When the sinking material discharge device 30 is in operation, the sinking material will operate along with the movement of the sinking material discharge device 30, and will not accumulate in other locations to cause blockage or be dispersed in dead corners that the sinking material discharge device 30 does not contact, resulting in not being transported out, thereby affecting the efficiency of sinking material transportation.

[0035] In this embodiment, refer to Figure 1-Figure 2 As shown, the floating material outlet 101 and the sinking material outlet 102 are both located at a height above the height of the separation liquid that can be accommodated within the housing 10. With this arrangement, after separation, the sinking and floating materials are transported to the floating material outlet 101 and sinking material outlet 102 above the liquid level, respectively, by the sinking material discharge device and the floating material discharge device, and finally discharged from the device. Compared to other arrangements, the arrangement above the liquid level can reduce the loss of separation liquid caused by the sinking and floating materials during the discharge process, thereby reducing costs.

[0036] In this embodiment, refer to Figure 4As shown, it also includes a distributing device 40 for dispersing the plastic mixture, and the distributing device 40 is arranged in the accommodating chamber. Through the arrangement of the distributing device 40, the plastic mixture can be separated by the separating liquid and also by the distributing device 40, so as to better achieve the separation of floating material and sinking material, and the separation is more thorough. The distributing device 40 is directly arranged at the inlet of the shell 10 for pouring and mixing, ensuring that the mixed material can quickly contact the distributing device 40 after entering the separating liquid, and the distributing effect is better and more obvious. Specifically, the distributing device 40 is a distributing roller 401 and a distributing driver 402 for driving the distributing roller 401 to move; the distributing roller 401 is rotatably arranged on the shell 10, and a plurality of distributing sheets 4011 are provided on the side wall of the distributing roller 401. When in use, the distributing roller 401 is driven to rotate by the distributing driver 402 to break up the mixed material, which helps to separate the sinking and floating materials.

[0037] In this embodiment, refer to Figure 4 As shown, there are multiple groups of dividing blades 4011, all of which are arranged around the side wall of the dividing roller 401. At the same time, the inclined directions of two adjacent groups of dividing blades 4011 are opposite. The multiple groups of materials can increase the contact with the mixed material, and after the sinking material is separated, it can be squeezed downward to sink to the bottom. At the same time, the multiple dividing blades 4011 are designed to be inclined in opposite directions, so that during the rotation of the dividing roller, the dividing blades 4011 can contact the mixed material in different directions, making the separation of sinking and floating materials more thorough.

[0038] In this embodiment, refer to Figure 5 As shown, it also includes a cleaning device 50 for cleaning floating materials. The cleaning device 50 is arranged on the upper layer of the accommodating chamber. Through the above arrangement, the separated floating materials can be cleaned and classified to ensure that no sinking materials are mixed with the floating materials. The cleaning device 50 is arranged after the material separation device 40. As the second control process after the material separation process, the floating materials separated by the material separation device 40 float along the liquid surface to the cleaning device 50 station. The cleaning device 50 will then mix it with the separation liquid for cleaning, so that it is fully in contact with the separation liquid, and finally the sinking materials mixed with the floating materials can be separated and sunk to the bottom.

[0039] In this embodiment, refer to Figure 5As shown, the cleaning device 50 comprises a plurality of cleaning rollers 501 and a cleaning driver 502 for driving all of the cleaning rollers 501. Each cleaning roller 501 is rotatably mounted on the housing 10, and its rotation direction is the same as that of the material separation roller 401. When in use, the housing 10 is driven to rotate by activating the cleaning driver 502. At the same time, the rotation of the cleaning rollers 501 stirs the separation liquid surface, causing the floating material above the liquid surface to gradually move onto the cleaning rollers 501 below for the cleaning process. By providing multiple groups of cleaning rollers 501, the separation effect of the cleaning process can be improved by increasing the number of steps, making the final separation of sinking and floating materials more thorough.

[0040] Reference Figure 5 As shown, specifically, a plurality of cleaning paddles 5011 are provided on the side wall of the cleaning roller 501, wherein the cleaning paddles 5011 are arranged on the side wall of the cleaning roller 501 along the axial direction of the cleaning roller 501, and a bending portion is further provided on the non-fixed end of the cleaning paddle 5011. Through the above arrangement, the cleaning roller 501 can contact the mixed material through the plurality of cleaning paddles 5011 during the rotation process and press it into the separation liquid for full contact. At the same time, the axial arrangement and the bending portion of the cleaning paddle 5011 can also prevent the mixed material from escaping from the cleaning paddle 5011 during the process of pressing the mixed material into the separation liquid.

[0041] In this embodiment, refer to Figure 6 As shown, the floating material discharge device 20 includes a chain conveyor assembly 201, multiple toggle members 202 disposed on the chain conveyor assembly 201, and a toggle driver 203 for driving the chain conveyor assembly 201. The toggle member 202 is spaced apart with multiple scraper claws 2021. The floating material discharge device 20 is disposed behind the cleaning device 50. After the mixed material passes through the aforementioned distributing device 40 and cleaning device 50, it is finally discharged from the floating material outlet 101 by the floating material discharge device 20. During use, the chain conveyor assembly is activated by activating the toggle driver 203. At this time, the toggle member 202 disposed on the chain also rotates with the chain, and during this rotation, the floating material on the liquid surface is scooped up and discharged at the floating material outlet 101, completing the distribution of the floating material. The provision of multiple toggle members 202 can increase the frequency of scooping up the floating material on the liquid surface, preventing some floating material from being missed and affecting the discharge effect. At the same time, a plurality of scraping claws 2021 are vertically arranged on the toggle member 202 to increase the effective area of ​​the toggle member 202 for scooping floating materials, thereby increasing the efficiency of scooping floating materials.

[0042] In this embodiment, reference Figure 6As shown, in combination with the above-mentioned arrangement, a plurality of scraper claws 2021 are arranged at intervals on the toggle member 202. In addition to achieving the above-mentioned purpose of improving the efficiency of scooping floating materials, this arrangement can also allow the separation liquid to be retained from the gaps between the scraper claws 2021 and finally flow back into the containing chamber during the process of scooping floating materials, thereby reducing the loss of separation liquid in the process of discharging floating materials.

[0043] Under the premise that no conflict occurs, those skilled in the art may freely combine and superimpose the above-mentioned additional technical features.

[0044] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
