Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection equipment, and particularly relates to a sludge feeder. Background Art

[0002] The common equipment currently used to feed belt-type sludge dryers is a "sludge strip cutter." This machine consists of an extrusion mechanism consisting of two rollers densely covered with square grooves, each with a scraper at the bottom of each groove. As the two rollers move inward, the upper sludge is clamped into the square grooves and transferred to the lower end. A sludge blade placed in the lower groove then scrapes the sludge out of the square grooves, causing it to fall downward, completing the discharge process. However, because the sludge often contains yarn fibers and plastic film particles, the sludge outlet can easily become clogged, resulting in intermittent sludge discharge. The resulting sludge strips are less consistent and difficult to achieve uniform and stable discharge. Summary of the Invention

[0003] In view of the above shortcomings, the technical problem to be solved by the present invention is to provide a sludge feeder for improving the continuity of sludge transportation.

[0010] As a preferred solution of the present invention, the second baffle is swingably mounted on the bottom of the arc-shaped plate by a second screw, and a second flexible pad is provided between the second baffle and the sludge output device.

[0011] As a preferred solution of the present invention, the delivery pump further comprises a feed hopper and an extrusion frame, the arc-shaped plate is fixed in the extrusion frame, and the feed hopper is mounted on the extrusion frame.

DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] A sludge feeder includes a sludge output device 1 and a mud outlet assembly 3. The sludge is input into the mud outlet assembly 3 through the sludge output device 1, and then the mud outlet assembly 3 extrude the sludge out of the sludge feeder in the form of strips. The sludge output device 1 includes a feed hopper 16 and a conveying pump 2. The feed hopper 16 and the mud outlet assembly 3 are respectively arranged at both ends of the conveying pump 2. The sludge is pressurized by the conveying pump 2 and then input into the mud outlet assembly 3.

[0024] The conveying pump 2 includes an extrusion gear roller 14 and an extrusion frame 15. The extrusion gear 14 is installed in the extrusion frame 15. The sludge output device 1 also includes a frame 17 and an extrusion motor 18. The extrusion frame 15 and the extrusion motor 18 are installed on the frame 17. The feed hopper 16 is installed on the extrusion frame 15. Two mutually meshing extrusion gear rollers 14 are installed in the extrusion frame 15. The extrusion motor 18 is connected to one of the extrusion gear rollers 14 to drive the extrusion gear roller 14 to rotate, and the sludge is squeezed into the mud outlet assembly 3 through the extrusion gear roller 14.

[0025] The two extrusion tooth rollers 14 are respectively installed with a rotating shaft, and the extrusion tooth rollers 14 are rotatably installed on the extrusion frame 15 through the rotating shaft. A pulley 19 is installed on one of the rotating shafts, and the pulley 19 is connected to the pulley on the extrusion motor 18 through a belt, thereby driving the two extrusion tooth rollers 14 to rotate simultaneously. The cross-section of the extrusion tooth roller 14 is gear-shaped, so that the extrusion tooth roller 14 and the extrusion frame 15 cooperate to form a gear pump-like structure, which is convenient for squeezing the sludge into the mud outlet assembly 3, and at the same time, the large particles of sludge can also be refined, thereby facilitating the sludge to be extruded through the mud outlet assembly 3.

[0026] Two arc plates 15 - 1 are provided in the extrusion frame 15 and are coaxially arranged with the extrusion gear roller 14 . The first baffle 4 and the second baffle 5 are connected to the two arc plates 15 - 1 respectively. Preferably, the cross section of the arc plates 15 - 1 is semicircular.

[0027] The mud outlet assembly 3 includes a first baffle 4 and a second baffle 5 that are arranged opposite to each other, and the first baffle 4 and the second baffle 5 are arranged at an angle to each other, so that a plurality of unit extrusion outlets 13 are formed at the bottom of the first baffle 4 and the second baffle 5, and the first baffle 4 and the second baffle 5 are swingably connected, that is, during the use of the mud outlet assembly 3, the first baffle 4 or the second baffle 5 can receive external force and swing relative to each other, so that the gap between the first baffle 4 and the second baffle 5 becomes larger, thereby connecting the plurality of unit extrusion outlets 13.

[0028] The first baffle plate 4 and / or the second baffle plate 5 are provided with a cell groove 4-3 for forming a cell extrusion opening 13. In this embodiment, a plurality of cell grooves 4-3 are provided on the first baffle plate 4. Preferably, the spacing between adjacent cell grooves 4-3 is 1-3 mm. The opening of the cell groove 4-3 gradually increases from the middle of the first baffle plate 4 to the edge of the first baffle plate 4 or the second baffle plate 5.

[0029] The first baffle 4 and the second baffle 5 are both angle irons, which include a horizontal plate and a vertical plate. The horizontal plate is installed on the arc plate 15 - 1 , and a unit extrusion port 13 is formed between the vertical plates of the first baffle 4 and the second baffle 5 .

[0030] The bottoms of the first baffle 4 and the second baffle 5 abut against each other, and under normal circumstances, the sludge is discharged out of the mud outlet assembly 3 through the unit groove 4-3. During the sludge extrusion process, since the sludge contains filamentous or flaky impurities that are longer than the unit extrusion outlet 13, these impurities may be blocked in multiple unit extrusion outlets 13. In this embodiment, by driving the second baffle 5 to swing, a gap is generated between the first baffle 4 and the second baffle 5, thereby connecting multiple unit extrusion outlets 13, facilitating the discharge of filamentous or flaky impurities in the unit extrusion outlet 13 along with the sludge, thereby preventing the unit extrusion outlets 13 from being blocked.

[0031] Side baffles 20 are respectively provided on both sides of the first baffle 4 and the second baffle 5 to make the mud outlet assembly 3 funnel-shaped to prevent the mud from being squeezed out from both sides of the first baffle 4 and the second baffle 5 .

[0032] A first screw hole 4-1 is provided on the first baffle 4, and a first screw 4-2 is provided in the first screw hole 4-1. The first screw 4-2 is used to install the first baffle 4 on the sludge output device 1. A first flexible pad 12 is provided between the first baffle 4 and the arc plate 15-1 of the sludge output device 1, and the first baffle 4 is supported by the first flexible pad 12.

[0033] Since there is easily a gap between the first screw 4-2 and the first screw through hole 4-1, the first baffle 4 can swing relative to the first screw 4-2. In order to fix the first baffle 4 on the sludge output device 1, a pressing member 11 is provided on the sludge feeder. The pressing member 11 includes a pressing connecting plate 11-1 and a pressing screw 11-2 connected to the frame 17. The pressing screw 11-2 is installed on the pressing connecting plate 11-1 through a thread. After the first baffle 4 is installed on the arc plate 15-1, the pressing screw 11-2 is rotated to abut its end against one side of the first baffle 4. As the pressing screw 11-2 continues to rotate, the first baffle 4 is pressed against the arc plate 15-1, thereby fixing the first baffle 4 on the sludge output device 1.

[0034] A second screw hole 5-1 is provided on the second baffle 5, and a second screw 7 is provided in the second screw hole 5-1. The second screw 7 is used to install the second baffle 5 on the sludge output device 1. The aperture of the second screw hole 5-1 is larger than the diameter of the second screw 7. Preferably, the aperture of the second screw hole 5-1 is 1.05~1.1 times the diameter of the second screw 7, so that the second baffle 5 can swing relative to the first screw 7.

[0035] A second flexible pad 8 is provided between the second baffle 5 and the sludge output device 1. The second flexible pad 8 seals the gap between the second baffle 5 and the sludge output device 1. At the same time, the second flexible pad 8 supports the second baffle 5 to ensure that the second flexible pad 8 swings with the hexagonal head of the second screw 7 as a fulcrum.

[0036] In order to facilitate driving the second baffle 5 to swing, the sludge feeder also includes a drainage-promoting driving component 9, which is connected to the second baffle 5 through a connecting component 10, and drives the second baffle 5 to swing through the drainage-promoting driving component 9.

[0037] The drainage driving component 9 includes a drainage motor 9-1, a cam 9-2 and a cam connecting rod 9-3. The cam 9-2 is installed on the drainage motor 9-1. The upper end of the cam connecting rod 9-3 is abutted against the bottom of the connecting member 10. The lower end of the cam connecting rod 9-3 is connected to the cam 9-2. The cam driving the cam connecting rod 9-3 to slide up and down drives one end of the connecting member 10 to rise and fall, thereby realizing the swing of the second baffle 5. By changing the working interval of the drainage motor 9-1, the swing time interval of the second baffle 5 can be changed, so that the swing interval of the second baffle 5 can be adjusted according to different types of sludge.
