[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] It will be understood that the terms "first" and "second" used in this application may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish a first element from another element.

[0035] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0036] like Figures 1 to 5 As shown, a vertical pressure solid-liquid dehydration device provided by an embodiment of the utility model includes:

[0037] Dehydration box 1, on which a drainage assembly 3 is installed for discharging sewage;

[0038] The dehydration component 2 is provided on the dehydration tank 1 and is used to dehydrate the sludge. The dehydration component 2 includes:

[0039] The dehydration motor 21 is fixedly mounted on the end surface of the dehydration box 1. The output end of the dehydration motor 21 is connected to the dehydration shaft 22. The dehydration shaft 22 rotates with the dehydration box 1.

[0040] The dehydration blades 23 are fixedly mounted on the dehydration shaft 22 and are used to transport the sludge. The spacing between the dehydration blades 23 gradually decreases from the side close to the dehydration motor 21 to the side away from the dehydration motor 21, so as to gradually increase the pressure of the sludge transportation.

[0041] The mud discharge port 24 is provided on the dewatering box 1 and is used for discharging the transported sludge.

[0042] In the embodiment of the utility model, in actual application, the dehydration motor 21 is started, and the dehydration blades 23 are driven to rotate through the dehydration shaft 22 to transport the sludge entering the dehydration box 1. Since the distance from one end to the other end of the dehydration blades 23 gradually decreases, the extrusion force on the sludge during the transportation process will gradually increase. When the sludge is transported, the sewage inside it will flow downward under the influence of vertical gravity. At the same time, the sludge will be affected by the extrusion force of the dehydration blades 23, accelerating dehydration and causing the sewage to be discharged through the drainage component 3.

[0043] By setting up the dehydration component 2, the sludge can be transported and dehydrated at the same time. The sewage in the sludge is discharged by utilizing the effect of gravity, and the sludge is dehydrated efficiently by the squeezing force perpendicular to gravity, avoiding the limitations of gravity concentration dehydration and other dehydration methods. In addition, the overall structural design is simple and easy to repair and maintain.

[0044] like Figures 1 to 5 As shown, as a further embodiment of the present invention, the drainage assembly 3 includes:

[0045] The fixing frame 31 is fixed on the dehydration box 1 by bolts;

[0046] The drainage filter cloth 32 is clamped on the fixing frame 31 and is used to filter and discharge sewage;

[0047] In the embodiment of the present invention, in actual application, the sewage discharged due to gravity and extrusion force will be initially filtered through the drainage filter cloth 32, thereby avoiding the simultaneous discharge of sludge and sewage, and the drainage filter cloth 32 is easy to disassemble, clean and replace through the fixing frame 31.

[0048] like Figures 1 to 5 As shown, as a further embodiment of the present invention, a transmission assembly 4 is further included, which is arranged on the dewatering box 1 and is used to cut the discharged sludge. The transmission assembly 4 includes:

[0049] The crank connecting rod 41 is fixedly mounted on the dehydration shaft 22;

[0050] The support frame 42 is movably mounted on the crank connecting rod 41, and the support frame 42 is also slidably engaged with the dehydration box 1;

[0051] The cutter 43 is fixedly mounted on the end surface of the support frame 42 and is located directly above the mud discharge port 24;

[0052] Specifically, as a further embodiment of the present invention, the dehydration box 1 is further provided with a support groove 12 for limiting the travel of the support frame 42, and the lower end of the dehydration box 1 is fixedly mounted with a support leg and a mud discharge pipe 11;

[0053] In the embodiment of the utility model, in actual application, when the dehydration motor 21 drives the dehydration shaft 22, the crank connecting rod 41 will rotate synchronously with the dehydration shaft 22, so that the support frame 42 is affected by the support groove 12 to make reciprocating linear motion on the dehydration box 1. When the support frame 42 moves, the cutter 43 cuts the sludge at the mud discharge port 24 downward, so that the dehydrated sludge becomes small pieces and falls from the mud discharge pipe 11, which is convenient for the transportation and reprocessing and recycling of the sludge.

[0054] like Figures 1 to 5 As shown, as a further embodiment of the present invention, a feeding assembly 5 is further included, which is arranged on the dewatering box 1 and is used to feed the dewatered sludge. The feeding assembly 5 includes:

[0055] The feed hopper 51 is fixedly mounted on the upper end of the dehydration box 1;

[0056] The feed inclined plate 52 is fixedly mounted on the inner wall of the feed hopper 51, and the two feed inclined plates 52 are symmetrically distributed along the central axis of the feed hopper 51;

[0057] Iron plates 53 are fixedly mounted on both feed inclined plates 52;

[0058] Electromagnet 54, an electromagnet 54 is fixedly installed in each of the two feed inclined plates 52, and one end of the electromagnet 54 is also connected to the iron plate 53;

[0059] The rotating roller 55 is rotatably engaged with the feed hopper 51, and a plurality of rows of winding rods 56 are fixedly mounted on the rotating roller 55;

[0060] Specifically, as a further embodiment of the present invention, a plurality of rows of winding rods 56 are equidistantly distributed along the circumferential direction of the rotating roller 55, and two adjacent rows of winding rods 56 are staggered.

[0061] In the embodiment of the present utility model, in actual application, the sludge falls into the dehydration box 1 through the feed hopper 51, and the electromagnet 54 is energized to generate magnetic force on the iron plate 53, which magnetically adsorbs some metal objects in the sludge. The sludge continues to slide, causing the rotating roller 55 to rotate, and the winding rods 56 distributed in a staggered manner on the rotating roller 55 stir the sludge and entangle it with the plastic bag impurities in the sludge, thereby separating the impurities in the sludge and avoiding interference with the dehydration of the sludge.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
