Description

Technical Field

[0001] The utility model relates to an intelligent dehydration device, in particular to an intelligent dehydration device for sludge treatment applied in the field of sludge treatment. Background Art

[0002] In order to protect water sources and the environment, polluted water must be treated before it can be discharged or directly recycled. Some sewage contains a lot of sludge. When treating this type of sewage, the water in the sludge must be dehydrated, and then the sludge and discharged water must be treated.

[0003] Most of the existing sludge dewatering devices dewater the sludge by belt dewatering or centrifugal dewatering. For sludge with a high moisture content, the belt dewatering machine can only squeeze the sludge once during the dewatering process, and the squeezed sludge is then transported to other devices for secondary or even multiple dewatering operations. Centrifugal dewatering is more suitable for sludge with a lower moisture content. For sludge with a relatively high moisture content, the dewatering effect is not ideal. Not only does it fail to achieve the desired dewatering effect, but it also has a high cost, resulting in low sludge dewatering efficiency. Utility Model Content

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that in the process of sludge dehydration, for sludge with a high moisture content, the effects of belt dehydrators and centrifugal dehydrators are not rational, the dehydration efficiency is low, and the sludge dehydration cost is increased.

[0005] In order to solve the above problems, the utility model provides an intelligent dewatering device for sludge treatment, including a support table, a receiving groove is opened at the upper end of the support table, two support plates are fixedly connected to the upper end of the support table, the two support plates are respectively located at the front and rear sides of the upper end of the receiving groove, the corresponding ends of the two support plates are rotatably connected to the two rotating plates, the corresponding ends of the two rotating plates are fixedly connected to the mounting plate through a fixing rod, a belt conveyor is fixedly connected between the two mounting plates, a plurality of drainage holes are opened through the surface of the conveying belt of the belt conveyor, a filter cloth is fixedly sleeved on the outer ring of the conveying belt of the belt conveyor, the rotating shafts of the two rotating plates located at the front end pass through the support plate, a pulley group is fixedly installed on the outer surfaces of the rotating shafts of the two rotating plates, a mounting groove is opened on the front inner wall of the receiving groove, a rotating motor is fixedly connected in the mounting groove, and the rotating motor is fixedly connected to the rotating shaft of one of the rotating plates, the upper end of the support table is also fixedly connected to a supporting cover, the left and right ends of the inner top wall of the supporting cover are respectively fixedly connected to a guide box and a plurality of cylinders, and the lower ends of the plurality of cylinders are fixedly connected to a pressing plate.

[0006] In the above-mentioned intelligent dewatering equipment for sludge treatment, when in use, for sludge with a high water content, multiple squeezing operations can be performed on it to squeeze out the water inside it, thereby improving the efficiency of sludge dewatering and reducing the dewatering cost.

[0007] As a further improvement of the present application, a feed hopper is fixedly connected to the upper end of the support cover, the feed hopper is located directly above the guide box, the guide box is inclined to the lower right, and the lower end of the guide box is located on the upper left of the belt conveyor.

[0008] As a further improvement of the present application, the rotating plate is elliptical, and the fixing rod of the mounting plate is not coaxial with the rotating plate.

[0009] As a further improvement of the present application, the pressure plate is located directly above the belt conveyor, and the width of the pressure plate is consistent with the width of the conveyor belt of the belt conveyor.

[0010] As another improvement of the present application, the lower end of the support platform is fixedly connected with a liquid collecting box and a discharge plate, respectively, and the lower end of the liquid collecting box is fixedly connected with a water outlet pipe, which is communicated with the liquid collecting box.

[0012] To sum up, in the actual application process, the sludge is put into the feed hopper and flows into the upper end of the belt conveyor through the guide box. At this time, the sludge is above the filter cloth. The belt conveyor is started to transport the sludge to the bottom of the pressing plate. The cylinder is started to drive the pressing plate to move downward to squeeze the sludge. The moisture in the sludge passes through the filter cloth and the hydrophobic holes and falls into the liquid collecting box. At the same time, the rotating motor is started to rotate to rotate the rotating plate, thereby driving the belt conveyor to make a circular reciprocating motion, so that the sludge on its surface is squeezed with the pressing plate for multiple times, and the sludge is dehydrated for multiple times, thereby improving the efficiency of sludge dehydration. After dehydration is completed, the belt conveyor is started again to discharge the dehydrated sludge from the equipment through the discharge plate, thereby dehydrating the sludge with a higher water content for multiple times, improving the dehydration efficiency and reducing the dehydration cost.

DETAILED DESCRIPTION

[0021] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0022] The first implementation method:

[0023] Figure 1 and Figure 2 It is shown that an intelligent dewatering device for sludge treatment includes a support platform 1, a receiving groove is provided at the upper end of the support platform 1, a support cover 10 is fixedly connected to the upper end of the support platform 1, and the support cover 10 can support the guide box 11 and the cylinder 12. The left and right ends of the inner top wall of the support cover 10 are respectively fixedly connected with the guide box 11 and multiple cylinders 12. Those skilled in the art can select a suitable type of cylinder 12 according to actual needs, for example: SCD50x100-100-LB, and the lower ends of the multiple cylinders 12 are commonly fixedly connected with a pressing plate 13, and the pressing plate 13 can squeeze the sludge. The pressing plate 13 is located directly above the belt conveyor 5, and the width of the pressing plate 13 is consistent with the width of the conveyor belt of the belt conveyor 5. The upper end of the support cover 10 is fixedly connected to a feed hopper 14, and the feed hopper 14 is located directly above the guide box 11. The guide box 11 is inclined to the lower right, and the lower end of the guide box 11 is located at the upper left of the belt conveyor 5, which is convenient for the guide box 11 to discharge the sludge to the top of the belt conveyor 5. The lower end of the support platform 1 is respectively fixedly connected to a liquid collecting box 15 and a discharge plate 16, and the lower end of the liquid collecting box 15 is fixedly connected to a water outlet pipe, which is communicated with the liquid collecting box 15 to facilitate the discharge of the squeezed water.

[0024] Figure 3 and Figure 4It is shown that: the upper end of the support platform 1 is fixedly connected to two support plates 2, and the two support plates 2 are respectively located at the front and rear sides of the upper end of the accommodating groove. The corresponding ends of the two support plates 2 are rotatably connected to two rotating plates 3, and the corresponding ends of the two rotating plates 3 are fixedly connected to the mounting plate 4 through the fixing rod. The rotation of the rotating plate 3 can drive the movement of the mounting plate 4, so that the belt conveyor 5 makes a circular reciprocating motion to squeeze the sludge multiple times. The belt conveyor 5 is fixedly connected between the two mounting plates 4. Those skilled in the art can select a suitable type of belt conveyor 5 according to actual needs, for example: WX201. The conveying belt surface of the belt conveyor 5 is penetrated with a plurality of drainage holes 6. The outer ring of the conveyor belt of the machine 5 is fixedly sleeved with a filter cloth 7, which facilitates solid-liquid separation of the sludge. The rotating shafts of the two rotating plates 3 at the front end pass through the supporting plate 2, and the outer surfaces of the rotating shafts of the two rotating plates 3 are fixedly installed with a pulley group 8. The pulley group 8 can drive the two rotating plates 3 to rotate at the same time. An installation groove is provided on the front inner wall of the accommodating tank, and a rotating motor 9 is fixedly connected in the installation groove. Those skilled in the art can select a suitable type of rotating motor 9 according to actual needs, for example: Y2-63M1-2-0.18KW, the rotating motor 9 is fixedly connected to the rotating shaft of one of the rotating plates 3, the rotating plate 3 is elliptical, and the fixing rod of the mounting plate 4 is not coaxial with the rotating plate 3.

[0025] When in use, the sludge is put into the feed hopper 14, and flows into the upper end of the belt conveyor 5 through the guide box 11. At this time, the sludge is located above the filter cloth 7. The belt conveyor 5 is started to transport the sludge to the bottom of the pressing plate 13, and the cylinder 12 is started to drive the pressing plate 13 to move downward to squeeze the sludge. The moisture in the sludge passes through the filter cloth 7 and the hydrophobic holes 6 and falls into the liquid collecting box 15. At the same time, the rotating motor 9 is started to rotate, so that the rotating plate 3 rotates, thereby driving the belt conveyor 5 to make a circular reciprocating motion, so that the sludge on its surface is squeezed with the pressing plate 13 for multiple times, and the sludge is dehydrated for multiple times, thereby improving the efficiency of sludge dehydration. After dehydration is completed, the belt conveyor 5 is started again to make the dehydrated sludge discharged from the equipment through the discharge plate 16, thereby dehydrating the sludge with a higher water content for multiple times, improving the dehydration efficiency and reducing the dehydration cost.

[0026] The second implementation method:

[0027] Based on the first embodiment, this embodiment adds a guide rail 17, a linear motor 18, an L-shaped rod 19 and a scraper 20, and the rest of the parts are consistent with the first embodiment.

[0028] Figure 5 and Figure 6It is shown that: two guide bars 17 are fixedly connected to the upper end of the support cover 10, and a linear motor 18 is fixedly installed in the guide bar 17. Technical personnel in this field can select a suitable type of linear motor 18 according to actual needs, for example: TJKK50. The movement of the linear motor 18 can drive the scraper 20 to move. The lower end of the linear motor 18 passes through the support cover 10 and is fixedly connected to an L-shaped rod 19. A scraper 20 is fixedly connected between the two L-shaped rods 19. The scraper 20 can scrape off the sludge sticking to the lower surface of the pressure plate 13.

[0029] During use, after the sludge is dehydrated, the cylinder 12 is started to contract to reset the pressing plate 13, and then the linear motor 18 is started to move, driving the L-shaped rod 19 to move to the left, so that the upper end of the scraper 20 contacts the lower end of the pressing plate 13. As the linear motor 18 moves, the scraper 20 scrapes the lower end of the pressing plate 13, thereby scraping the sludge adhering to the surface of the pressing plate 13 onto the belt conveyor 5, and finally falls onto the surface of the discharge plate 16 for discharge.

[0030] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
