Description

Technical Field

[0001] The utility model relates to the technical field of sludge dehydration, and in particular to a super multi-station high-pressure sludge extrusion structure. Background Art

[0002] In the process of urban sewage treatment, the water content of sludge produced by water purification treatment is generally 99.3% to 99.7%, activated sludge is generally 99.2% to 99.6%, and mixed sludge is generally 97% to 98%. The characteristics of urban sludge are less solid matter and more water. Therefore, sludge needs to be concentrated before dehydration to reduce the water content of sludge and reduce the volume of sludge for easy dehydration.

[0003] After searching, the Chinese patent publication number CN211311276U discloses "a sludge squeezing assembly, comprising a shell and a rotating shaft, the rotating shaft is rotatably connected to the side wall of the shell, one end of the rotating shaft extends into the shell, the end of the rotating shaft away from the shell is connected to a driving device, the rotating shaft is threadedly connected to a slider on the outer wall of the shell, the end of the rotating shaft away from the driving device is rotatably connected to a support plate, the circumferential side of the support plate is connected to the inner side wall of the shell, the side of the support plate away from the driving device is provided with a first pressure plate that slidably cooperates with the inner wall of the shell, the two sides of the slider are respectively connected to one end of the fixed shaft, the other end of the fixed shaft passes through the support plate and is connected to the first pressure plate, a second pressure plate is slidably cooperated in the shell, and a sludge squeezing cavity is formed between the first pressure plate and the second pressure plate".

[0004] This type of patent drives the movement of the "drive shaft" through the rotation of the "disc" to make the "piston" reciprocate in the "cylinder", so that the "second pressure plate" slides circularly on the inner wall of the "shell", thereby squeezing and impacting the sludge so that the water in the sludge flows out through the water filter holes; this structure has only one set of upper and lower pressure plate squeezing stations to squeeze the sludge, so the amount of sludge dehydrated by a single squeezing is very small, which leads to poor sludge treatment efficiency. In view of this, the utility model proposes a multi-station high-pressure sludge squeezing structure. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1~Figure 5 As shown, this embodiment proposes an ultra-multi-station high-pressure sludge extrusion structure, including a shell 1, a plurality of extrusion chambers 2 are opened inside the shell 1, and the plurality of extrusion chambers 2 are evenly distributed along the length direction of the shell 1. The top ends of the inner sides of the plurality of extrusion chambers 2 are provided with upper extrusion members 5 for extruding the upper layer of sludge, and the bottom ends of the inner sides of the extrusion chambers 2 are provided with lower extrusion members 6 for extruding the lower layer of sludge. The top of the shell 1 is provided with a driving member 7 for driving the upper extrusion member 5 and the lower extrusion member 6 to reciprocate up and down, and the upper extrusion member 5 and the lower extrusion member 6 move in opposite directions.

[0026] A plurality of extrusion chambers 2 are provided with a through feed port 3 on their inner walls, and the feed port 3 is located between the initial position of the upper extrusion member 5 and the initial position of the lower extrusion member 6; a plurality of through water filter holes 4 are provided in the middle of the inner walls of the plurality of extrusion chambers 2, and the plurality of water filter holes 4 are evenly distributed along the horizontal direction.

[0027] The sludge is introduced into the corresponding extrusion chamber 2 through a plurality of feed ports 3, and then the upper extrusion member 5 and the lower extrusion member 6 in each extrusion chamber 2 are used to extrude the upper and lower layers of the sludge respectively through the driving member 7, so that the water in the sludge in each extrusion chamber 2 is squeezed out and discharged through the corresponding water filter hole 4. The whole structure can dehydrate the sludge in a plurality of extrusion chambers at the same time, which greatly increases the treatment amount of single sewage, and thus greatly improves the treatment efficiency of sludge dehydration.

[0028] Furthermore, the upper extrusion member 5 includes a first slide bar 51, which penetrates the top wall of the corresponding extrusion chamber 2 and is slidably connected to the top wall of the extrusion chamber 2. The bottom end of the first slide bar 51 is fixedly connected to an upper pressure plate 52, which is slidably connected to the inner wall of the extrusion chamber 2. The top end of the first slide bar 51 is fixedly connected to a mounting seat 53, which is located above the housing 1. A pressing wheel 54 is rotatably connected to the inner side of the mounting seat 53. A return spring 55 is sleeved on the first slide bar 51, and the top end of the return spring 55 contacts the mounting seat 53, and the bottom end of the return spring 55 contacts the top wall of the housing 1. The upper pressure plate 52 can slide downward in the corresponding extrusion chamber 2 by sliding the first slide bar 51 downward, so that the upper pressure plate 52 squeezes the upper layer of sludge in the extrusion chamber 2.

[0029] Further, the lower extrusion member 6 includes a plurality of second slide bars 61 corresponding to the upper pressing plate 52 one by one, the plurality of second slide bars 61 penetrate the bottom wall of the corresponding extrusion chamber 2 and are slidably connected to the bottom wall of the extrusion chamber 2, the top ends of the plurality of second slide bars 61 are fixedly connected to the lower pressing plate 62, the plurality of lower pressing plates 62 are slidably connected to the inner wall of the corresponding extrusion chamber 2, the bottom ends of the plurality of second slide bars 61 are fixedly connected to the same connecting plate 63, the two ends of the top of the connecting plate 63 are fixedly connected to push rods 64, the side walls on both sides of the housing 1 are fixedly connected to guide seats 65, the two push rods 64 penetrate the two guide seats 65 respectively, and are slidably connected to the corresponding guide seats 65. The connecting plate 63 can be moved upward by sliding the two push rods 64 upward, which makes all the second slide bars 61 slide upward synchronously, and also makes all the lower pressing plates 62 slide upward in the corresponding extrusion chamber 2, so that all the lower pressing plates 62 squeeze the lower layer of the sludge inside the corresponding extrusion chamber 2.

[0030] Furthermore, the driving member 7 includes two fixed plates 71 arranged in parallel, the bottom ends of the two fixed plates 71 are fixedly connected to the two ends of the top of the shell body 1 respectively, the top ends of the two fixed plates 71 are rotatably connected to the same rotating shaft 72, and a plurality of cams 73 corresponding to the pressure wheels 54 are fixedly connected to the rotating shaft 72, and the plurality of cams 73 are intermittently in contact with the corresponding pressure wheels 54; a worm gear 74 is fixedly connected to the rotating shaft 72, and the worm gear 74 is located between two adjacent cams 73; a motor 75 is fixedly installed at one end of the top of the shell body 1, and a worm 76 is fixedly connected to the output shaft of the motor 75, and the worm 76 is meshed with the worm gear 74.

[0031] Furthermore, both ends of the rotating shaft 72 are fixedly connected with eccentric wheels 77, and the two eccentric wheels 77 are respectively located on the outside of the two fixed plates 71. The outer edges of the two eccentric wheels 77 are rotatably connected with connecting rods 78 through pins. The ends of the two connecting rods 78 away from the corresponding eccentric wheels 77 are hinged with connecting seats 79, and the bottoms of the two connecting seats 79 are respectively fixedly connected to the top ends of the two push rods 64.

[0032] Working principle: When working, the worm 76 is rotated by starting the motor 75, which causes the worm wheel 74 to rotate synchronously, and the rotating shaft 72 is rotated, so that all the cams 73 rotate synchronously. When the cam 73 contacts the corresponding pressing wheel 54, the pressing wheel 54 moves downward under the action of the cam 73. At this time, the return spring 55 is squeezed to accumulate elastic potential energy, so that the mounting seat 53 drives the first slide bar 51 to move downward; when the cam 73 is disengaged from the corresponding pressing wheel 54, the return spring 55 releases potential energy, which makes the mounting seat 53 drive the first slide bar 51 to move upward, and the cycle is repeated. The first slide bar 51 can slide back and forth up and down, thereby making the plurality of upper pressing plates 52 slide back and forth up and down in the corresponding extrusion chamber 2;

[0033] When the rotating shaft 72 rotates, it will drive the two eccentric wheels 77 to rotate synchronously, so that the two connecting rods 78 drive the corresponding pushing rods 64 to move up and down reciprocatingly, and the connecting plate 63 drives all the second sliding rods 61 to slide up and down reciprocatingly, and then all the lower pressure plates 62 slide up and down reciprocatingly in the corresponding extrusion chamber 2; when the upper pressure plate 52 slides downward, the lower pressure plate 62 slides upward at this time, so that the upper pressure plates 52 and the lower pressure plates 62 in all the extrusion chambers 2 can extrude and dehydrate the sludge at the same time, greatly increasing the single sludge processing volume, and also improving the sludge dehydration efficiency; the whole process is driven by a single motor 75, so that the activities of the upper pressure plate 52 and the lower pressure plate 62 share a driving source, which can save the use of resources and reduce the use cost.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
