In the muddy water screw conveyor provided by the embodiment, in the working process, materials (in the embodiment, a mixture of sludge and water is taken as an example, other water-containing materials can be actually used) are poured into the conveying pipeline 100 from the feed inlet 108, the motor 106 drives the rotating shaft 102 to rotate and drives the spiral blade 104 to rotate, the spiral blade 104 pushes the materials to move along the conveying pipeline 100, under the action of vibration and sedimentation of the materials, moisture gradually floats above the materials and flows downwards from the liquid discharge pressure relief channel 112 to the feed inlet 108, when the liquid level of the feed inlet 108 submerges the liquid outlet 114, the water is discharged onto the liquid baffle 122 through the liquid guide pipe 116, the water on the liquid baffle 122 works on the driven gear 118 towards the rotating direction by virtue of gravity and finally flows into the recovery box 124, and compared with the prior art, the falling water is effectively utilized, the falling water is recovered, and the pollution to the working environment is reduced; under the condition that the amount of conveyed materials is kept unchanged, as the water applies work to the driven gear 118 in the rotating direction, the energy consumption of the motor 106 is reduced, the energy saving effect is achieved, the load of the motor 106 is lightened, and the service life of the motor 106 is prolonged; on the other hand, in the prior art, in the process of pushing materials by the spiral conveying blades, a certain closed cavity is generated in the space between each pitch of the spiral conveying blades 104, when the materials in the closed cavity are partially leaked, the air pressure in the closed cavity is reduced, when the materials flow into the sealed cavity, the air pressure in the sealed cavity is increased, when the air pressure is increased, water in the sealed cavity flows out from the weld seam holes on the side wall of the conveying pipeline 100, so that concentrated water drainage or concentrated water collection is difficult to realize, the working environment is polluted, and the embodiment can enable the sealed cavities to be communicated with each other by arranging the liquid discharge and pressure relief channel 112, so that the air pressure in the sealed cavity is prevented from being increased or reduced, the concentrated water discharge from the liquid discharge port 114 is facilitated, the water is conveniently recovered, the pollution to the working environment caused by the leaked water is also reduced, meanwhile, the obstruction of the air pressure resistance to the rotation and axial pushing of the spiral conveying blades 104 is also reduced, and the energy consumption is facilitated to be reduced. The right-to-left arcuate arrow in fig. 3 refers to the direction of rotation of the driven gear 118.

When the spiral blade 104 pushes materials, the materials have certain viscosity and fluidity, the properties of the materials are uneven, the materials are in an uneven filling state in each interval space (the space between two adjacent spiral blades 104 in a screw pitch or a lead) of the spiral blade 104, the space is less, the space is more, the space is filled with the materials, the materials in the unfilled space slowly flow downwards and gather, the materials are deposited at the bottom of the space, the top is empty and are communicated through the liquid discharge and pressure relief channel 112, moisture in the water is above sludge, in the communicated space in the conveying pipeline 100, the moisture in the upper space flows to the lower space, after the space is filled with the material, the water in the space above the space filled with the material overflows from the liquid discharge and pressure relief channel 112 to the lower space, and the materials in the conveying pipeline 100 are difficult to enter the liquid discharge and pressure relief channel 112, namely the materials enter the liquid discharge and pressure relief channel 112, the liquid discharge and pressure relief channel 112 is also required to be blocked by the water in the space, and the liquid discharge and pressure relief channel is not blocked by the diameter of the liquid discharge and pressure relief channel 112 is increased if the diameter of the liquid discharge and pressure relief channel is increased, and the diameter of the liquid discharge and pressure relief channel is increased if the diameter is small than the diameter of the liquid discharge and pressure relief channel is required to be blocked by the diameter of the liquid discharge and the diameter is small.

The motor 106 adopts a gear motor, and can output a low rotation speed and a large torque, the rotation speed is 20 revolutions per minute, the materials in the conveying pipeline 100 are pushed and move upwards slowly, and the materials cannot be stirred by the spiral blade 104 (when stirring exists, the materials can slide relatively) or are thrown into the liquid discharge and pressure relief channel 112. Because the rotation speed of the motor is slower and the diameter of the driving gear 120 is smaller than that of the driven gear 118, the rotation speed of the driven gear 118 is smaller, after water flows onto the liquid baffle 122, the water can gradually flow to one end far away from the center of the circle along with the inclination of the liquid baffle 122, the driven gear 118 is set to be in an inclined state, the liquid baffle 122 is positioned on one inclined upward side of the driven gear 118, therefore, a part of water can be accumulated on the liquid baffle 122, the length of the liquid baffle 122 is larger, the weight of the water can generate larger torque at the center of the driven gear 118, because the motor 106 transmits the torque to the helical blade 104, the helical blade 104 is slowly rotated by the torque force, the load of the motor 106 is reduced compared with the situation that the torque is generated without water assistance, the electric energy consumption is reduced, the heat generated by the coil winding in the motor 106 due to the larger load is reduced, the working efficiency of the motor 106 is improved, the work done on water is idle work in the process of pushing up water in the material by the spiral blade 104, the water is left on the liquid baffle 122 to generate torque to reduce the load of the motor 106 so as to reduce energy consumption, the recovery and utilization of a part of the idle work of water are realized, the water is collected, the recovery and utilization rate of the idle work of the water is related to the water content in the material, the higher the water content is, the more the water backflow is, the more the energy consumption of the motor 106 is reduced, the more the long-term work accumulation is, the water content in the material is 20 percent, the water backflow is 10 percent, the water quantity involved in generating torque is 5 percent, the energy consumption reduction efficiency is 80 percent, the energy consumption reduction is 0.4 percent, the conveying quantity of the material is gradually increased, the total energy consumption is reduced, the total energy consumption reduction is considerable along with the pushing of the service time, because the rotation speed of the fluid plate 122 is slow, the amount of water involved in torque generation is actually greater.

Preferably, the motor 106 is set to be a variable frequency motor, and is controlled by a PLC controller, a strain gauge or other torque sensing element is disposed between the output shaft of the motor 106 and the driving gear 120, and the sensing element is used for detecting the torque generated by the output shaft of the motor 106, so as to be used as a basis for the load of the motor 106, and the sensing element is connected with the PLC controller, and the PLC controller controls the magnitude of the output torque of the motor 106 according to the magnitude of the load of the motor 106, for example, the smaller the load is, the smaller the torque output by the motor 106 is, so that the torque transmitted to the helical blade 104 by the motor 106 is kept constant (the fluctuation of the torque is reduced, which does not mean to be completely constant), and the working stability is improved.

In some exemplary implementations of this embodiment, the end of the catheter 116 remote from the drain port 114 is located above the center of the driven gear 118.

Through the above-mentioned exemplary embodiment of the present embodiment, the water is discharged and collected above the center of the driven gear 118, which is helpful for prolonging the time that the water stays on the liquid baffle 122, prolonging the time that the water does work on the driven gear 118, and increasing the work done on the driven gear 118 by the water in unit volume, thereby being helpful for improving the energy-saving effect and prolonging the service life of the motor 106.

In some exemplary implementations of the present embodiment, as shown in connection with fig. 4-6, a fluid sump 126 is provided on one side of the fluid shield 122, the fluid sump 126 being oriented opposite the direction of rotation of the driven gear 118.

With the above-described exemplary embodiment of the present embodiment, it is advantageous to retain more water on the liquid blocking plate 122 in a unit time period, increase the work performed by the water on the driven gear 118, and preferably, the distance between the end of the liquid blocking plate 122 away from the center of the driven gear 118 and the rotation shaft 102 is greater than the radius of the driven gear 118 (as shown in fig. 3), and increase the torque generated by the water on the driven gear 118 in the rotation direction.

In some exemplary implementations of the present embodiment, the depth of the fluid bath 126 increases gradually in a direction away from the central axis of the shaft 102.

With the above-described exemplary embodiment of the present embodiment, the amount of torque generated by the water to the driven gear 118 in the rotational direction is related to the position of the point of application of the water on the liquid blocking plate 122, and the greater the point of application is from the center of the driven gear 118, the greater the torque generated to the driven gear 118 in the rotational direction, and therefore the greater the depth of the liquid bath 126 from the center of the driven gear 118 (as shown in fig. 6), more water can be collected at the position of the point of application of the greater torque generated per unit time, contributing to the improvement of the effective utilization rate of the water.

In some exemplary implementations of the present embodiment, the shaft 102 and the delivery conduit 100 are disposed obliquely.

By the above-described exemplary embodiment of the present embodiment, the side of the driven gear 118 near the conveying pipe 100 is inclined upward, and after the water flows onto the side of the driven gear 118 near the conveying pipe, the driven gear 118 can receive and guide the water, so that more water flows onto the liquid baffle 122, the retention time of the water on the liquid baffle 122 is prolonged, and the amount of water that does not flow through the liquid baffle 122 but directly flows into the recovery tank 124 is reduced.

In some exemplary implementations of the present embodiment, the output shaft of the motor 106 is disposed horizontally, and the driving gear 120 and the driven gear 118 are bevel gears.

With the above-described exemplary embodiment of the present embodiment, the larger the inclination angle of the driven gear 118, the smaller the torque generated by the water to the driven gear 118 in the rotation direction at the same point of application, the smaller the inclination angle, the longer the length of the conveying pipe 100 and the shorter the residence time of the water on the liquid blocking plate 122, with the conveying lift unchanged, and the three main aspects of the generated torque magnitude, the length of the conveying pipe 100, and the residence time of the water on the liquid blocking plate 122 being taken into consideration, it is preferable that the angle between the rotation shaft 102 and the conveying pipe 100 and the horizontal plane be set to be between 30 degrees and 45 degrees (this angle range is not meant to be usable only in this range, but in practice the inclination angle can also be reduced, which is one exemplary angle range of the present embodiment); the output shaft of the motor 106 is horizontally arranged, so that the axial acting force applied to the output shaft of the motor 106 is reduced, and the axial acting force applied to the shell of the motor 106 by the output shaft of the motor 106 is reduced, so that the abrasion is reduced, the working stability of the motor 106 is improved, and the service life of the motor 106 is prolonged; because of the relative inclination between the output shaft of the motor 106 and the shaft 102, the use of bevel gears for the meshing drive is advantageous in that the output shaft of the motor 106 is disposed horizontally and the combined effect of the motor and the inclined shaft 102 is not merely a bevel gear option.

In some exemplary implementations of this embodiment, the feed port 108 is located at the lower top of the transfer conduit 100 and the discharge port 110 is located at the upper bottom of the transfer conduit 100.
