[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0017] Please refer to Figures 1-8 As shown, the present invention provides a waste slurry separation and resource classification and recovery device for the preparation of recycled concrete, including a separation and recovery component 100. Inside the separation and recovery component 100, multiple sets of extrusion separation arm assemblies 200 are provided. Between the multiple sets of extrusion separation arm assemblies 200, a separation membrane cloth 300 is provided. The multiple sets of extrusion separation arm assemblies 200 are longitudinally distributed in a row inside the separation and recovery component 100. When the separation and recovery component 100 is not airtight, through the synchronous drive of the multiple sets of extrusion separation arm assemblies 200, a waste slurry separation structure with multi-chamber separation is formed inside the separation membrane cloth 300. When the separation and recovery component 100 is airtight, a solid-liquid separation structure of vacuum low-temperature evaporation is formed inside the separation and recovery component 100.
[0018] In a preferred implementation manner, please refer to Figure 4 and Figure 5 , the separation and recovery component 100 includes a separation and recovery cylinder 101. At the top and bottom of the separation and recovery cylinder 101, sealing covers 110 for sealing the ports of the separation and recovery cylinder
[0019] In a preferred embodiment, see Figure 7 and Figure 8 The extrusion separation arm assembly 200 includes a first ring frame 201 and a second ring frame 208. The first ring frame 201 is fixedly provided with a ring frame arm 202. The outer side of the second ring frame 208 is fixedly provided with an edge frame 207. The edge frame 207 is fixedly provided with a guide rail slide 206 and a tooth 209. The second ring frame 208 is rotatably provided with a first assisting arm 204. The first ring frame 201 is rotatably provided with a second assisting arm 205. The intersection of the first assisting arm 204 and the second assisting arm 205 is rotatably provided with an end platform 203. The first ring frame 201 is fixed to the inner wall of the separation and recovery cylinder 101 through the ring frame arm 202. The guide rail slide 206 rotates in the annular slide groove 112, and the second ring frame 208 is set on the inner wall of the separation and recovery cylinder 101 through the coordinated rotation of the guide rail slide 206 and the annular slide groove 112. A plurality of first assisting arms 204 are rotatably set on the second ring frame 208, and the plurality of first assisting arms 204 are ringed on the frame body of the second ring frame 208. A plurality of second assisting arms 205 are rotatably set on the first ring frame 201, and the plurality of second assisting arms 205 are ringed on the frame body of the first ring frame 201. An enclosing structure is formed between the plurality of end platforms 203, and the separation membrane cloth 300 is fixed between the plurality of enclosed end platforms 203.
[0020] The working principle of the present invention is as follows: when the present invention is used, the top and bottom of the separation recovery cylinder 101 must be opened. At this time, the first gear 102 is driven to rotate by the first motor 103, and the first gear 102 drives the bottom group of extrusion separation arm assemblies 200 to move through the teeth 209. At this time, the action of the extrusion separation arm assembly 200 causes the bottom of the separation membrane cloth 300 to be retracted. At this time, the coagulant waste slurry is poured in from the top of the separation membrane cloth 300, and then the pneumatic second motor 106 drives the synchronous action of the top multiple groups of extrusion separation arm assemblies 200 through the cooperation of the second gear 105 and the teeth 209. At this time, the top of the separation membrane cloth 300 is retracted and forms an interval-type retraction structure. Through this retraction structure, the extrusion separation of the coagulant waste slurry in the separation membrane cloth 300 is realized, and through this graded and layered separation extrusion, while realizing the extrusion separation, the separated solid materials are separated synchronously to avoid stacking into a pile, which is convenient for subsequent vacuum low-temperature evaporation-type solid-liquid separation.
[0021] It should also be noted that when the first gear 102 drives the extrusion separation arm assembly 200 to act, the first gear 102 drives the second ring frame 208 to rotate through the teeth 209. When the second ring frame 208 rotates, since the first ring frame 201 is fixed, the rotation of the second ring frame 208 will drive the first assisting arm 204 to rotate. Since the second assisting arm 205 is fixed on the first ring frame 201, the end platform 203 at the intersection of the first assisting arm 204 and the second assisting arm 205 forms a converging structure at this time. The end platform 203 is fixed on the separation membrane 300. When multiple end platforms 203 converge synchronously, a converging extrusion structure will be formed between the separation membranes 300. In this way, the solid-liquid separation of concrete is realized, which is convenient for subsequent recovery.
[0022] On the above basis, after the separation membranes 300 are separated and extruded by grading and layering, at this time, the hydraulic cylinder 107 drives the sealing cover 110 to seal the port of the separation and recovery cylinder 101. At this time, the heating rod inside the heating chamber 111 raises the temperature inside the separation and recovery cylinder 101. At this time, the vacuum pump 109 makes the inside of the separation and recovery cylinder 101 form a vacuum environment. Since the boiling point of the liquid decreases in a vacuum environment, in this way, the liquid separation of the remaining materials after the concrete extrusion separation is further realized. In this way, on the one hand, the dryness of the remaining materials after the concrete extrusion separation is ensured, and the incomplete separation of the remaining materials after the concrete extrusion separation is avoided, etc. On the other hand, by this way of boiling of the low-temperature liquid, the difficulty of solid-liquid separation is reduced.
[0023] On the above basis, through the action of multiple groups of extrusion separation arm assemblies 200 of the present invention, a multi-chamber separated waste slurry separation structure is formed inside the separation membrane 300. Through this structure, the remaining materials after the concrete extrusion separation are separated into a non-accumulating structure, which cooperates with the vacuum low-temperature evaporation type solid-liquid separation structure inside the separation and recovery assembly 100 to further ensure the separation effect of the concrete waste slurry. When the separation is completed, the hydraulic cylinder 107 drives the sealing cover 110 to reset. At this time, the port of the separation and recovery cylinder 101 is opened. At this time, the second gear 105 and the first gear 102 rotate in the reverse direction. At this time, multiple groups of extrusion separation arm assemblies 200 form an outward expansion structure. At this time, the separated remaining materials inside the separation membrane 300 can be collected and recovered.
[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
