[0016] Depend on Figure 1-4 A concentrating device for sludge treatment is provided, comprising a box body 1, the box body 1 has openings on the left and right sides, two limit bars 2 are fixedly connected to the front and rear side walls of the inner cavity of the box body 1, the two limit bars 2 are fixed to the inner side wall of the box body 1, the two limit bars 2 are parallel to each other in the upper and lower parts, an extrusion mechanism 3 is arranged on the upper outer wall of the box body 1, the extrusion mechanism 3 extends to the inside of the box body 1, and an opening and closing mechanism 4 is arranged on the left and right sides of the box body 1;

[0017] The extrusion mechanism 3 includes a mounting frame 31 and an extrusion plate 33. The mounting frame 31 is an inverted U-shaped plate structure. The mounting frame 31 is fixedly sleeved on the middle part of the upper end of the box body 1. The middle part of the upper end of the mounting frame 31 is fixedly connected with a servo motor 32. The output shaft of the servo motor 32 passes through the mounting frame 31. The extrusion plate 33 is slidably connected inside the box body 1. The two sides of the lower end of the extrusion plate 33 are slidably engaged with the upper parts of the two limit bars 2 respectively. A slide groove 34 is provided on the top of the extrusion plate 33. The slide shaft 35 is slidably engaged inside the slide groove 34. A connecting rod 36 is fixedly sleeved on the upper part of the slide shaft 35. The left end of the connecting rod 36 is fixedly connected to the output shaft of the servo motor 32.

[0020] The sludge treatment and concentrating device of the utility model, when needed to be used, the two box covers 41 are both in the closed state, and the external sludge can be first poured into the box body 1 from the feeding rack 44 on the left side of the squeezing plate 33. After the loading is completed, the servo motor 32 drives the connecting rod 36 to rotate and cooperates with the slot hole of the slide slot 34 through the sliding shaft 35, which can drive the squeezing plate 33 to move to the left and squeeze the sludge. The limit bar 2 can play a limiting and guiding role for the squeezing plate 33 and enable the squeezing plate 33 to maintain a horizontal state and move horizontally. With the continuous pushing of the squeezing plate 33, the moisture in the sludge is squeezed out and discharged through the drainage hole 45. At the same time, the sludge is squeezed into a mud cake and stays in the left box cover 41. In the process of squeezing the left sludge, it can be fed from the feeding rack 44 on the right. After the squeezing and concentration of the left sludge is completed, the servo motor 32 drives the connecting rod 36 to rotate and cooperates with the slot hole of the slide slot 34 through the sliding shaft 35. It can drive the squeezing plate 33 to move to the left and squeeze the sludge. The limit bar 2 can play a limiting and guiding role for the squeezing plate 33 and enable the squeezing plate 33 to maintain a horizontal state and move horizontally. With the continuous pushing of the squeezing plate 33, the moisture in the sludge is squeezed out and discharged through the drainage hole 45. At the same time, the sludge is squeezed into a mud cake and stays in the left box cover 41. In the process of squeezing the left sludge, it can be fed from the feeding rack 44 on the right. With the continuous rotation of the motor 32, the squeezing plate 33 moves horizontally to the right and squeezes the sludge on the right, while the push rod 46 on the left pushes the box cover 41 on the left to rotate with the hinge buckle 43 as the center. The box cover 41 drives the mud cake on the left to flip together, and after flipping a certain angle, it falls out under the action of gravity. After the unloading is completed, the box cover 41 is reset and loaded again, while waiting for the sludge on the right to be processed and then processed again, and so on. By alternating the two opening and closing mechanisms 4 and coordinating the left and right lateral movement of the squeezing plate 33, the chamber on the other side can be loaded while the sludge on one side is being concentrated, and the unloading process on the other side can be completed while the sludge on one side is being processed. Compared with the prior art, there is no need to spend time waiting for the discharge and reloading before performing the secondary operation. This method improves the efficiency of the sludge concentration treatment.
