Technical Field
[0001] The utility model belongs to the technical field of sludge dewatering machines, in particular to a vibration compression type sludge dewatering machine. Background Art
[0002] After sewage treatment, sewage treatment plants will produce a large amount of sludge with a water content of 95% to 98%. At present, sewage treatment plants use mechanical dehydration methods for sludge dehydration. The dehydration machines include vacuum belt conveyors, centrifugal dehydrators, plate and frame filter presses, belt filter presses, etc. These mechanical dehydration methods can only reduce the water content of the sludge to between 78% and 82%. In addition, the equipment occupies a large area, has a poor operating environment, requires a large amount of maintenance, has high operating costs, and is inconvenient to use.
[0003] At present, auger compression is commonly used for dehydration. However, during the compression process, sludge and sewage will form relatively stable small groups, which will greatly reduce the effect of compression dehydration. Utility Model Content
[0004] In order to solve the above-mentioned problem, the utility model provides a vibration compression sludge dewatering machine which can vibrate and compress the sludge to prevent the sludge from forming relatively stable small groups during compression and dehydration, thereby improving the dehydration quality and dehydration efficiency.
[0005] In order to achieve the above functions, the technical solution adopted by the utility model is as follows: a vibrating compression sludge dewatering machine comprises an outer shell, a spiral main shaft is installed inside the outer shell, a spiral extrusion blade is sleeved on the spiral main shaft, an annular groove rail is arranged on the relative inner side walls of the outer shell, a dewatering cylinder is movably installed in the annular groove rail, a contact column is movably penetrated through the center of the top wall of the outer shell, the bottom end of the contact column is connected to the top end of the dewatering cylinder, a spring is sleeved on the contact column, one end of the spring is connected to the inner top wall of the outer shell, and the other end of the spring is connected to the top wall of the dewatering cylinder, a bracket is arranged on the top wall of the outer shell, a driving motor is installed on the bracket, an eccentric wheel is connected to the output end of the driving motor, and the bottom of the eccentric wheel is arranged in contact with the top end of the contact column.
[0006] As a preferred technical solution of the utility model, the spiral extrusion blades are arranged with a certain taper.
[0007] As a preferred technical solution of the utility model, a mud inlet is arranged on the top wall of the outer shell, the mud inlet is connected to the dewatering cylinder through a hose, and a mud discharge nozzle is arranged on the bottom wall of the outer shell.
[0008] As a preferred technical solution of the utility model, the dehydration cylinder is configured as a water-permeable mesh structure with openings at both ends.
[0009] As a preferred technical solution of the utility model, a bracket is provided on the left outer wall of the outer shell, a rotating motor is installed on the bracket, and the output end of the rotating motor passes through the side wall of the outer shell and is connected to the spiral main shaft.
[0010] As a preferred technical solution of the utility model, drainage holes are evenly opened on the bottom wall of the outer shell.
[0011] As a preferred technical solution of the utility model, the inner diameter of the annular groove rail is larger than the outer diameter of the dehydration cylinder.
[0012] Compared with the prior art, the utility model adopts the above structure to achieve the following beneficial effects:
[0013] 1. The spiral extrusion blades are set at a certain taper. When the spiral extrusion blades drive the sludge to the sludge discharge port for transmission and dehydration, the internal pressure gradually increases, which is conducive to the rapid separation of mud and water;
[0014] 2. The dewatering cylinder is equipped with an eccentric wheel structure to drive the dewatering cylinder to vibrate and squeeze the sludge between the dewatering cylinder and the spiral extrusion blades. The sludge is vibrated and compressed, making it difficult for the structure of the sludge mass to stabilize, thus preventing the sludge from forming relatively stable small groups during compression and dehydration, thereby improving the dewatering quality and dewatering efficiency.

DETAILED DESCRIPTION
[0020] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. The present utility model is further described in detail below in conjunction with the accompanying drawings.
[0022] like Figure 1-4 As shown, the utility model provides a vibration compression type sludge dewatering machine, including an outer shell 1, a spiral main shaft 2 is installed inside the outer shell 1, a spiral extrusion blade 3 is sleeved on the spiral main shaft 2, the spiral extrusion blade 3 is set in a certain taper, the internal pressure gradually increases, which is conducive to the rapid separation of mud and water, and an annular groove rail 4 is arranged on the relative inner side wall of the outer shell 1. The inner diameter of the annular groove rail 4 is larger than the outer diameter of the dewatering cylinder 5. The dewatering cylinder 5 is movably installed in the annular groove rail 4, and the dewatering cylinder 5 is set as a water-permeable mesh cover The outer shell 1 has a structure with openings at both ends. A contact column 6 is movable and penetrates the center of the top wall of the outer shell 1. The bottom end of the contact column 6 is connected to the top of the dehydration cylinder 5. A spring 7 is sleeved on the contact column 6. One end of the spring 7 is connected to the inner top wall of the outer shell 1, and the other end of the spring 7 is connected to the top wall of the dehydration cylinder 5. A bracket 8 is arranged on the top wall of the outer shell 1, and a drive motor 9 is installed on the bracket 8. An eccentric wheel 10 is connected to the output end of the drive motor 9, and the bottom of the eccentric wheel 10 is arranged in contact with the top of the contact column 6.
[0023] Specifically, the driving motor 9 drives the eccentric wheel 10 to rotate eccentrically, and the eccentric wheel 10 squeezes the contact column 6, so that the spring 7 is in a compressed state. At the same time, the dewatering cylinder 5 also moves downward in the annular groove 4, squeezing the sludge between the top of the dewatering cylinder 5 and the top of the spiral squeezing blade 3. When the eccentric wheel 10 moves to the side where it is not squeezing the contact column 6, the reset force of the spring 7 causes the contact column 6 to elastically vibrate and reset, driving the dewatering cylinder 5 to vibrate and squeeze the sludge between the dewatering cylinder 5 and the spiral squeezing blade 3.
[0024] like Figure 1-3As shown, the top wall of the outer shell 1 is provided with a mud inlet 11, and the mud inlet 11 is connected to the dehydration cylinder 5 through a hose, and the bottom wall of the outer shell 1 is provided with a mud discharge nozzle 12, and a bracket 13 is provided on the left outer wall of the outer shell 1, and a rotating motor 14 is installed on the bracket 13, and the output end of the rotating motor 14 passes through the side wall of the outer shell 1 and is connected to the spiral main shaft 2, and the bottom wall of the outer shell 1 is evenly provided with drainage holes 15.
[0025] During specific use, the sludge is transported into the dewatering cylinder 5 from the mud inlet 11 and the hose, the rotating motor 14 and the driving motor 9 are started, and the sludge is pushed toward the mud discharge nozzle 12 along the spiral extrusion blades 3. As the internal pressure gradually increases, the internal moisture is gradually squeezed out by the spiral extrusion blades 3, and the driving motor 9 drives the eccentric wheel 10 to rotate eccentrically. The eccentric wheel 10 squeezes the contact column 6, so that the spring 7 is in a compressed state. At the same time, the dewatering cylinder 5 also moves downward in the annular groove 4, squeezing the sludge between the top of the dewatering cylinder 5 and the top of the spiral extrusion blades 3. When the eccentric wheel 10 moves to the side where it is not squeezing the contact column 6, the reset force of the spring 7 causes the contact column 6 to elastically vibrate and reset, driving the dewatering cylinder 5 to vibrate and squeeze the sludge between the dewatering cylinder 5 and the spiral extrusion blades 3, and vibrating and compressing the sludge, making it difficult to stabilize the structure of the sludge mass, thereby avoiding the sludge from forming relatively stable small groups during compression and dehydration. The dewatered sludge is discharged from the mud discharge nozzle 12, and the sewage is discharged from the drainage hole 15.
