Description

Technical Field

[0001] The utility model relates to the technical field of dehydration devices, in particular to a filtering and dehydration device. Background Art

[0002] With the continuous increase of daily life and industrial wastewater, the scale and efficiency of sewage treatment are increasing, and sewage treatment equipment is gradually improving. Sludge is a by-product of the sewage treatment process, which contains both pollutants and a large amount of reusable resources. Recycling and utilizing the energy and resources in sludge has become the focus of people's research. Therefore, it is necessary to use a filtering and dehydrating device to filter and dehydrate the sludge in the sewage to achieve sewage reduction, stabilization and harmless treatment.

[0003] In order to separate solids from liquids in sewage, most existing filtration and dewatering devices are drum-type separation devices consisting of an outer drum and an inner drum. When in use, sewage is passed into the inner drum, which is provided with dewatering holes. The motor drives the inner drum to rotate and separate the solids and liquids by centrifugal force. However, during the dewatering process, the sludge in the sewage is heavy, and the inner drum will sway during the dewatering process, which can easily lead to unstable rotation of the inner drum and loud operating noise. In addition, it is troublesome to remove the separated sludge from the inner drum. Moreover, when the dewatering holes of the inner drum are blocked and need to be cleaned, it is inconvenient to remove the inner drum.

[0004] Therefore, it is particularly important to design a filtering and dehydrating device to solve the above-mentioned defects. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In the present invention, through the coordinated design of the sleeve, the telescopic rod, the spring, the first roller and the first annular slide rail, when the dehydration barrel rotates to generate centrifugal force to separate the solid and liquid of the sewage, the weight of the sludge in the sewage in the dehydration barrel causes the dehydration barrel to swing when rotating. The telescopic rod is moved into the sleeve to cause the spring to contract to offset the force of the swing, thereby reducing the noise generated by the rotation of the dehydration barrel. At the same time, the four groups of first rollers are on the outside of the dehydration barrel. As the dehydration barrel rotates, the first rollers roll in the first annular slide rail, thereby improving the stability of the rotation of the dehydration barrel and enhancing the dehydration effect of the dehydration barrel.

In the present invention, through the coordinated design of the support frame and the device body, after the sewage in the dehydration barrel is separated into solid and liquid, the cover on the top of the device body is opened, and then the device body is swung to dump the solid sludge in the dehydration barrel. At the same time, when the dehydration hole of the inner cylinder needs to be cleaned, the dehydration barrel can be conveniently taken out, which greatly improves the convenience of the filtering and dehydration device.

DETAILED DESCRIPTION

[0020] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Example

[0022] This embodiment provides a filtering and dehydrating device, which can play a good role in solid-liquid separation when filtering and dehydrating sewage, while increasing the stability of the dehydration barrel 3 and improving the overall convenience of the device.

[0023] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0024] A filtering and dehydration device includes a support frame 1, a device body 2 is provided on the inner side of the support frame 1, a dehydration barrel 3 is provided inside the device body 2, a machine box 4 is provided at the bottom end of the device body 2, a drive motor 5 is provided inside the machine box 4, a turntable 6 is provided at the bottom end of the dehydration barrel 3, the driving end of the drive motor 5 is connected to the bottom of the turntable 6, four groups of sleeves 7 are provided on the outside of the dehydration barrel 3, a telescopic rod 8 is provided at the end of the sleeve 7 away from the dehydration barrel 3, a spring 9 is provided inside the telescopic rod 8, a first roller 10 is provided at the end of the telescopic rod 8 away from the sleeve 7, and a first annular slide rail 11 is provided at a position corresponding to the first roller 10 on the inner side of the device body 2.

[0025] In this embodiment, the implementation scenario is specifically as follows: when filtering and dehydrating the sludge in the sewage, the device body 2 is first opened and the sewage is then loaded into the interior of the dehydration barrel 3, and then the device body 2 is closed, and the driving motor 5 in the chassis 4 is immediately started to drive the turntable 6 to rotate, thereby driving the dehydration barrel 3 to rotate, and the centrifugal force generated by the rotation of the dehydration barrel 3 is used to separate the solid and liquid of the sewage. During the rotation of the dehydration barrel 3, the weight of the sludge in the sewage causes the dehydration barrel 3 to deflect when rotating, and the telescopic rod 8 is moved into the sleeve 7 to cause the spring 9 to contract to offset the force of the deflection, thereby reducing the dehydration. The noise generated when the barrel 3 rotates, and at the same time, the four groups of first rollers 10 on the outside of the dehydration barrel 3 rotate with the dehydration barrel 3, and the first rollers 10 roll in the first annular slide rail 11, thereby improving the rotation stability of the dehydration barrel 3. Finally, after the sewage is separated into solid and liquid, the solid sludge separated out is opened, and the device body 2 is opened and swung using the support frame 1 to complete the dumping of the solid sludge in the dehydration barrel 3. The entire operation process is simple and convenient. Compared with the existing filtering and dehydration device, the utility model can improve the overall stability, convenience and practicality of the filtering and dehydration device through design.

[0026] First, see Figure 1-Figure 3 A control box 12 is provided on the left side of the support frame 1. The control box 12 is electrically connected to the drive motor 5. Fixed frames 13 are provided on the left and right sides of the support frame 1. The outer side of the device body 2 is rotatably connected to the fixed frame 13 through a connecting rod. After the sewage is loaded into the dewatering barrel 3 inside the device body 2, the control box 12 is used to start the drive motor 5 to drive the dewatering barrel 3 to rotate. Finally, after the solid-liquid separation of the sewage, the device body 2 is opened and the support frame 1 is used to swing the device body 2, so that the dehydrated solid sludge in the dewatering barrel 3 is dumped out;

[0027] Then, a sealing cover 14 is provided on the top of the device body 2, and a handle is provided on the top of the sealing cover 14, and a rotating block 15 is provided on the left side of the sealing cover 14. The rotating block 15 is located on the inner side of the sealing cover 14 and is provided with a threaded column. A fixed block is provided at one end of the threaded column close to the device body 2, and four groups of second rollers 16 are provided on the outside of the sealing cover 14, and the four groups of second rollers 16 are evenly spaced and distributed on the outside of the dewatering barrel 3. A second annular slide rail 17 is provided at the bottom of the sealing cover 14 corresponding to the second roller 16. Rotating the rotating block 15 causes the threaded column to rotate toward the outside of the sealing cover 14, so that the fixed block releases the fixation of the sealing cover 14, thereby opening the sealing cover 14 and pouring the sewage into the dewatering barrel 3 in the device body 2. At the same time, after the sealing cover 14 is closed, the second roller 16 rolls in the second annular slide rail 17 when the dewatering barrel 3 rotates, further improving the rotation stability of the dewatering barrel 3;

[0028] Furthermore, a plurality of fixing plates 20 are provided at the top of the turntable 6 and on the outside of the dehydration barrel 3, and the fixing plates 20 are evenly spaced on the top of the turntable 6. The fixing plates 20 are used to fix the dehydration barrel 3 on the top of the turntable 6 to ensure the stability of the dehydration barrel 3. At the same time, when the dehydration holes on the dehydration barrel 3 need to be cleaned, the dehydration barrel 3 can be removed from the top of the turntable 6 by opening the device body 2, which is convenient for cleaning the dehydration barrel 3.

[0029] Secondly, the telescopic rod 8 is connected to the sleeve 7 in a sliding manner. The spring 9 is equipped with a damper. Four groups of sleeves 7 are evenly spaced outside the dehydration barrel 3. When the dehydration barrel 3 rotates, the multiple groups of telescopic rods 8 move toward the inside of the sleeve 7 with the dehydration barrel 3's yaw force, causing the spring 9 to contract and offset the yaw force, thereby reducing the noise generated when the dehydration barrel 3 rotates.

[0030] Finally, a guide plate 18 is provided at the bottom end of the interior of the device body 2 and on the outside of the chassis 4. A filter box 19 is provided at the bottom end of the device body 2. Multiple groups of filter plates are provided inside the filter box 19. A drain pipe is provided on the right side of the filter box 19. The interior of the filter box 19 is interconnected with the interior of the device body 2. The sewage separated from the dehydration barrel 3 enters the filter box 19 through the diversion of the guide plate 18, and after being filtered by the filter plates in the filter box 19, it is finally discharged through the drain pipe.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
