Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, in particular to a pulp filtering and dewatering device. Background Technique

[0002] Recycled pulp is also called waste paper pulp. Since the varieties and properties of recycled paper and cardboard are different, the waste paper pulp made from general waste paper and cardboard is mostly used as the filler pulp for low-strength cardboard, and some packaging paper or building cardboard is produced. In the process of recycling waste paper pulp, it is often necessary to dehydrate it for subsequent treatment. A pulp filtering and dewatering device described in the publication number CN210946277U can re-filter the squeezed water through a filter plate and a water-absorbing material. The filtered pulp remains on the filter plate and moves along its inclined direction to the collection tank under the action of gravity. The water-absorbing material can absorb the water attached to the filter plate after filtration, thereby improving the filtering effect of the filter plate. However, the prior art still has the following defects:

[0003] 1. The prior art only relies on two squeezing rollers for dehydration, and the dehydration effect is average, and the water content of the pulp is still relatively high;

[0004] 2. When filtering in the prior art, the pulp is prone to accumulate on the filter plate under the action of gravity, affecting the subsequent filtering effect. Content of the Utility Model

A cavity is provided inside the box body 1 for dewatering the pulp.

[0045] Among them, the cover plate 2 is detachably connected to the upper side of the box body 1, and a sealing ring is provided at the bottom end of the cover plate 2 to maintain the sealing of the inside of the box body 1. The feed inlet 3 penetrates through the cover plate 2 and is fixedly connected to it. The guide frame 5 is detachably connected to the lower end of the cover plate 2, which can limit the movement path of the pulp and is convenient for cleaning the inside of the guide frame 5 after it is disassembled.

[0046] The dewatering component 6 is rotatably connected to the inner wall of the guide frame 5. The dewatering component 6 includes: a first roller 61, a second roller 62, a transmission belt 63, and a first motor 64. The four first rollers 61 are respectively rotatably connected to the upper and lower ends of the front and rear inner walls of the guide frame 5, and the four first rollers 61 are symmetrically distributed in pairs. The six second rollers 62 are respectively rotatably connected to the front and rear inner walls of the guide frame 5, and the six second rollers 62 are also symmetrically distributed, with three on each side. A transmission belt 63 for connection is wound between the two first rollers 61 and the three second rollers 62 on each side. A first motor 64 for cooperating with the upper first roller 61 is fixedly connected to the outer wall of the rear side of the box body 1. The two first motors 64 are connected by an external controller to maintain the synchronism of the two first motors 64. The controller is a prior art and will not be elaborated here. The output end of the first motor 64 penetrates through the box body 1 and the guide frame 5 and is rotatably connected to both of them. The output end of the first motor 64 is connected to the upper first roller 61 to provide the power required for its movement. By starting the first motor 64, the upper first roller 61 can be driven to move, and in cooperation with the lower first roller 61 and the second roller 62, the transmission belt 63 can be driven to move. When the pulp enters between the second rollers 62 on both sides, it will be squeezed to realize the dewatering treatment of the pulp and effectively reduce the water content of the pulp.

[0047] The filtering component 7 is used in cooperation with the material guiding frame 5 and is fixedly connected to the inner wall of the box body 1. The filtering component 7 includes: a fixing plate 71, a second motor 72, a cam 73, a push plate 74, a connecting rod 75, and a filtering frame 76. The fixing plate 71 is fixedly connected to the outer wall of the box body 1. The second motor 72 is fixedly connected to the lower side of the fixing plate 71. The cam 73 is used in cooperation with the second motor 72 and is rotatably connected to the upper side of the fixing plate 71. The output end of the second motor 72 penetrates through the fixing plate 71 and is fixedly connected to the cam 73. The push plate 74 is located above the fixing plate 71 and abuts against the rear side of the cam 73. Two connecting rods 75 penetrate through the side wall of the box body 1 and are fixedly connected to the rear side of the push plate 74. The connecting rods 75 penetrate through the side wall of the box body 1 and are slidably connected thereto. A spring for cooperating with the box body 1 is sleeved on the connecting rod 75. The two ends of the spring are respectively fixedly connected to the front outer wall of the filtering frame 76 and the front inner wall of the box body 1. The front outer wall of the filtering frame 76 is fixedly connected to the connecting rod 75. The size of the filtering frame 76 is much larger than that of the material guiding frame 5, preventing the pulp from falling outside the screening frame 76 when it falls from the inside of the material guiding frame 5 during its vibration process. By starting the second motor 72, the cam 73 can be driven to rotate. Cooperating with the spring sleeved on the connecting rod 75, the push plate 74 starts to drive the connecting rod 75 to perform reciprocating motion in the front-back direction, realizing the vibration filtering of the pulp, improving the filtering effect while avoiding the pulp from blocking the filtering frame and affecting the subsequent pulp processing.

[0048] Two collection boxes 8 are movably connected to the inner wall of the box body 1, respectively used to collect the filtered pulp and other impurities. A handle 9 is fixedly connected to the front outer wall of the collection box 8. Two iron limiting blocks are fixedly connected to the lower outer wall of the collection box 8. Four limiting grooves for cooperating with the limiting blocks are provided on the lower inner wall of the cavity. Magnets are arranged inside the limiting grooves. After inserting the collection box 8 into the cavity along the limiting grooves, the magnets will generate an attractive force on the limiting blocks, fixing the collection box 8 inside the box body 1 and preventing it from falling out of the box body 1 without manual force.

[0049] Embodiment 2:

[0050] The solution in Embodiment 1 will be further introduced below in combination with the specific working mode. See the following description for details:

The front and rear ends of the spring are respectively fixedly connected to the filtering frame 76 and the telescopic rod 77. While the cam 73 drives the push plate 74, the telescopic rod 77 will also, under the action of the spring, assist the filtering frame 76 to perform reciprocating motion, further improving the stability of the device and the filtering effect.

[0052] Embodiment 3:

[0053] The solution in Embodiment 2 will be further introduced below in combination with the specific working mode. See the following description for details:

[0054] On both inner walls of the feeding port 3, two baffle plates 4 are rotatably connected. At the lower end of the baffle plate 4, a damping rod 41 used in cooperation with the feeding port 3 is rotatably connected. The lower end of the damping rod 41 is rotatably connected to the inner wall of the feeding port 3. A spring is sleeved on the damping rod 41, and the upper and lower ends of the spring are fixedly connected to the baffle plate 4 and the damping rod 41 respectively. The spring can drive the damping rod 41 to move, so that when there is no pulp entering, it can push the baffle plate 4 back to the horizontal position to prevent impurities such as dust from the outside from entering the interior of the device and affecting the subsequent processing of the pulp.
