Description

Technical Field

[0001] The utility model relates to the field of sludge drying, and more specifically, to a sludge drying feeding device. Background Art

[0002] The sewage treatment process includes the treatment of sludge, wherein the treatment of sludge requires drying. The current process is to crush the sludge, extrude it into strips and then send it into a belt sludge drying box for drying. The feeding port of the extruder is at its top, so the sludge needs to be sent to a high place for feeding. In the existing technology, the sludge is mostly fed by a spiral dragon, and the sludge may contain other foreign matter, such as fiber cloth, branches, etc. Such foreign matter will enter the drying machine equipment and affect it, and will also affect the subsequent sludge treatment. Therefore, a feeding device that can filter sludge foreign matter is needed to ensure the feeding quality. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that 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] See also Figure 1-Figure 4 As shown, a sludge drying and feeding device includes a frame 1 and a sieve plate 7. A hopper 3 is installed on the upper part of one side of the frame 1. The hopper 3 is conical and has an open top, so that sludge can be poured into the hopper 3. Support platforms 301 are symmetrically provided on the upper part of both sides of the hopper 3. A slide bar 4 slides vertically through the surface of the support platform 301. The slide bar 4 can slide in the vertical direction. A cross plate 5 is connected between the tops of the two slide bars 4 on the same side. The cross plate 5 can move up and down. The sieve plate 7 is suspended at the open top of the hopper 3 to effectively filter the sludge entering the hopper 3. Extension rods 702 are symmetrically provided on both sides of the sieve plate 7. There are four extension rods 702 in total. The two extension rods 702 on the same side are respectively installed at both ends of the cross plate 5, so that the sieve plate 7 can move together with the cross plate 5, thereby realizing the vibration of the sieve plate 7. A connecting plate 9 is installed below the surface of the two slide bars 4, and an arc-shaped boss 901 is provided in the center of the upper surface of the connecting plate 9. Eccentric wheels 10 are rotatably installed on both sides of the hopper 3. The eccentric wheel 10 is placed between the connecting plate 9 and the cross plate 5. The surface of the eccentric wheel 10 is in contact with the arc-shaped boss 901. The arc-shaped boss 901 is pressed down by the rotation of the eccentric wheel 10, and then the screen plate 7 is driven to vibrate up and down. The two eccentric wheels 10 are coaxially connected and installed on the output end of the rotating motor. Its mounting shaft passes through the hopper 3 horizontally. A spring A6 is provided on the surface of the slide bar 4. The top of the spring A6 is in contact with the lower surface of the cross plate 5, and the bottom of the spring A6 is in contact with the upper surface of the support platform 301. The elastic force of the spring A6 is used to make the connecting plate 9 have an upward force, so that the arc-shaped boss 901 always keeps in contact with the surface of the eccentric wheel 10.

[0023] Please refer to Figure 3 and Figure 4 As shown, an adjusting nut 8 is screwed under the surface of the slide rod 4, and the adjusting nut 8 is placed under the connecting plate 9. By adjusting the nut 8, the distance between the connecting plate 9 and the cross plate 5 can be controlled, and then the height of the screen plate 7 can be controlled.

[0024] Please refer to Figure 2As shown, a through hole 703 is provided on the surface of the side where the two extension rods 702 on the same side are close to each other, and a handle 701 is provided on the side of the upper surface of the sieve plate 7 close to the through hole 703. The other side of the sieve plate 7 is hinged to the cross plate 5, and sliding bolts 11 are symmetrically slidably installed on both sides of one of the cross plates 5. The ends of the sliding bolts 11 are adapted to the internal dimensions of the through hole 703. By controlling the sliding bolts 11, it can be controlled whether it cooperates with the through hole 703, thereby causing one side of the sieve plate 7 to lose control and be reversed.

[0025] Please refer to Figure 3 As shown, an open slot 501 is provided at the center of the upper surface of the horizontal plate 5. A control plate 12 is vertically provided above the side where the two sliding bolts 11 are close to each other. The control plate 12 passes through the open slot 501. The two control plates 12 are parallel to each other. A spring B13 is provided inside the open slot 501 and is placed between the two control plates 12. The elastic force of the spring B13 forces the two control plates 12 to move away from each other, so that the sliding bolts 11 can automatically engage with the through holes 703 when no force is applied.

[0026] Please refer to Figure 1 As shown, auxiliary support rods 101 are symmetrically arranged on the side of the frame 1 away from the hopper 3, and a spiral conveying cylinder 2 is obliquely arranged between the two auxiliary support rods 101. The lower end of the spiral conveying cylinder 2 is connected to the bottom of the hopper 3, and a discharge pipe 201 is arranged below the high end of the spiral conveying cylinder 2 to transport the sludge inside the hopper 3.

[0027] Working principle: When in use, due to the presence of spring A6, the cross plate 5 is always subjected to an upward force, and then the screen plate 7 is in a suspended state. The starting motor can drive the eccentric wheel 10 to rotate. During the rotation, the connecting plate 9 can be pressed down through its contact with the arc-shaped boss 901, and then the screen plate 7 is driven to vibrate up and down, placing the sludge on the surface of the screen plate 7, which can be filtered through the screen plate 7 to prevent large-sized foreign matter from entering the hopper 3, and then the sludge is transported through the spiral conveying cylinder 2. When there are too many foreign matter on the surface of the screen plate 7, the two control plates 12 can be squeezed to make the two sliding bolts 11 close to each other, and then lose the cooperation with the through hole 703. At this time, the screen plate 7 can be turned over by the handle 701, and then the foreign matter on the surface of the screen plate 7 is dumped out.

[0028] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
