[0021] A sludge dewatering screw conveyor of the present utility model includes a conveying shell 101, a sludge inlet hopper 102 and a conveying assembly. The conveying assembly includes a driving member 103, a screw propeller 104, an assembly cover 105, two fixing members 106, a discharge frame 107, a blocking member 108, two support structures 109, two infrared ray sensors 110 and a controller 111. The support structure 109 includes a load-bearing frame 112, a telescopic rod 113, a support cylinder 114, a hydraulic cylinder 115 and a support base 116. The driving member 103 includes an electrical box 117, a driving motor 118 and a rotating shaft 119. The fixing member 106 includes a locking screw 120 and a nut 121. The blocking member 108 includes an electric telescopic cylinder 122, a connecting block 123 and a blocking plate 124. Through the foregoing solution, the problem of the existing sludge dewatering screw conveyor is solved. Since the height position of the support frame for supporting the conveying shell 101 is fixed, the height positions of the conveying shell 101 and the sludge discharge shell cannot be adjusted according to different usage situations, resulting in low versatility.

[0022] For this specific embodiment, the sludge inlet hopper 102 is used to receive sludge and then convey the sludge through the conveying assembly provided on the conveying shell 101.

[0023] Among them, the driving member 103 is arranged on one side of the conveying shell 101; the propeller 104 is fixedly connected to the driving member 103 and is located on one side of the driving member 103; the assembly cover 105 is located on the side of the conveying shell 101; the two fixing members 106 are respectively arranged on both sides of the assembly cover 105; the discharge frame 107 is communicated with the conveying shell 101 and is located on one side of the conveying shell 101; the blocking member 108 is arranged on one side of the discharge frame 107; the two supporting structures 109 are respectively located on one side of the conveying shell 101; the load-bearing frame 112 is fixedly connected to the conveying shell 101 and is located on one side of the conveying shell 101; the telescopic rod 113 is fixedly connected to the load-bearing frame 112 and is located on one side of the load-bearing frame 112; the support cylinder 114 is slidably connected to the telescopic rod 113 and is located on one side of the telescopic rod 113; the hydraulic cylinder 115 is fixedly connected to the support cylinder 114, and the output end of the hydraulic cylinder 115 is fixedly connected to the telescopic rod 113 and is located inside the support cylinder 114; the support base 116 is fixedly connected to the support cylinder 114 and is located on one side of the support cylinder 114. When transporting sludge, after detecting that the state of the propeller 104 in the conveying shell 101 is correct, the assembly cover 105 is buckled with the conveying shell 101 and fixed by the two fixing members 106. Subsequently, according to the usage situation, the hydraulic cylinder 115 in the support cylinder 114 is controlled to drive the telescopic rod 113 to stretch, and the conveying shell 101 is lifted through the load-bearing frame 112, so that the conveying shell 101 is moved to a suitable height position. Then, the blocking member is opened away from the discharge frame 107, and the sludge enters the conveying shell 101 through the mud inlet hopper 102. The propeller 104 is driven by the driving member 103 to rotate to transport the sludge to the discharge frame 107, and the sludge is transported to the receiving device through the discharge frame 107, thus solving the problem that the existing sludge dewatering screw conveyor has a low versatility because the height position of the support frame supporting the conveying shell 101 is fixed and thus the height positions of the conveying shell 101 and the sludge discharge shell cannot be adjusted according to different usage situations.

[0024] Secondly, the electrical control box 117 is fixedly connected to the conveying shell 101 and is located on one side of the conveying shell 101; the driving motor 118 is fixedly connected to the electrical control box 117 and is located inside the electrical control box 117; the rotating shaft 119 is fixedly connected to the output end of the driving motor 118 and is fixedly connected to the propeller 104 and is located on one side of the driving motor 118. The electrical control box 117 is used to support the installation of the driving motor 118, control the driving motor 118 to drive the rotating shaft 119 to rotate, the rotating shaft 119 is used to drive the propeller 104 to rotate, and the propeller 104 is used to convey the sludge.

[0025] Again, the locking screw 120 is threadedly connected to the assembly cover 105 and is located on one side of the assembly cover 105; the nut 121 is fixedly connected to the locking screw 120 and is located on one side of the locking screw 120. When the assembly cover 105 is buckled with the conveying housing 101, use a tool to twist the nut 121 so that the locking screw 120 is threadedly connected to the conveying housing 101, and then the fixing of the assembly cover 105 can be completed.

[0026] In addition, the electric telescopic cylinder 122 is fixedly connected to the discharge frame 107 and is located on one side of the discharge frame 107; the connecting block 123 is fixedly connected to the output end of the electric telescopic cylinder 122 and is located on one side of the electric telescopic cylinder 122; the blocking plate 124 is fixedly connected to the connecting block 123 and is located on one side of the connecting block 123. When sludge is being transported, control the electric telescopic cylinder 122 to drive the connecting plate to drive the blocking plate 124 away from the discharge frame 107, and then the discharge frame 107 can be opened.

[0027] Furthermore, two infrared ray sensors 110 are arranged mirror-symmetrically inside the mud inlet hopper 102; the controller 111 is fixedly connected to the electrical control box 117, and is electrically connected to the two infrared ray sensors 110 respectively, and is located on one side of the electrical control box 117. The two infrared ray sensors 110 are respectively arranged on both sides inside the mud inlet hopper 102. When sludge enters, the infrared rays are blocked, and then the infrared ray sensors 110 transmit the blocking signal to the controller 111. The controller 111 controls the driving motor 118 inside the electrical control box 117 to operate. When the infrared rays are not blocked, the controller 111 does not control the driving motor 118 to operate, so as to achieve the effect of reducing energy consumption. The infrared ray sensors 110 and the controller 111 both adopt existing technologies.

[0028] When using the utility model, when transporting sludge, after checking the state of the propeller 104 in the conveying shell 101 and finding it correct, the assembly cover 105 is buckled with the conveying shell 101. When the assembly cover 105 is buckled with the conveying shell 101, use a tool to twist the nut 121 so that the locking screw 120 is threadedly connected with the conveying shell 101 to complete the fixation of the assembly cover 105. Subsequently, according to the usage situation, control the hydraulic cylinder 115 in the support cylinder 114 to drive the telescopic rod 113 to stretch and lift the conveying shell 101 through the load-bearing frame 112, so that the conveying shell 101 moves to a suitable height position. Control the electric telescopic cylinder 122 to drive the connecting plate to drive the blocking plate 124 away from the discharge frame 107, and the discharge frame 107 can be opened. When the sludge enters the conveying shell 101 through the mud inlet hopper 102, it blocks the signal of the infrared ray sensor 110. Subsequently, the infrared ray sensor 110 transmits the blocking signal to the controller 111, and the controller 111 controls the driving motor 118 in the electrical control box 117 to operate. The driving motor 118 controls the rotating shaft 119 to drive the propeller 104 to rotate to transport the sludge to the discharge frame 107, and the sludge is transported to the receiving device through the discharge frame 107, thus solving the problem that in the existing sludge dewatering screw conveyor, since the height position of the support frame supporting the conveying shell 101 is fixed, the height positions of the conveying shell 101 and the sludge discharge shell cannot be adjusted according to different usage situations, resulting in low versatility.

[0029] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand the whole or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
