Technical Field

[0001] The utility model relates to the technical field of high-level boxes, and specifically relates to a high-level box for ensuring stable pulp flow. Background Art

[0002] In the process of pulp and paper production, in order to ensure the uniform distribution of pulp on the papermaking machine wire and obtain paper with consistent evenness, high-level boxes are usually used to stabilize the flow rate and pressure of pulp for small and medium-sized production lines with low production volume.

[0003] The reference patent publication number "CN204455701U" discloses a special high-level box for ensuring stable pulp flow, including a first chamber, a second chamber and a third chamber. The bottoms of the first chamber, the second chamber and the third chamber are all in an inverted conical shape, and the upper parts are all in a cylindrical shape. The first chamber and the second chamber are communicated through an overflow plate at the upper part.

[0004] This patent realizes the smooth rise of pulp. In the existing high-level box, by adopting a three-chamber structure, when feeding, the pulp fills the three chambers through overflow. During the initial feeding, due to the height difference, the pulp will fall at a relatively high height, which will cause the pulp to fluctuate, and then reduce the smoothness of the pulp flow. This problem will be more obvious especially when the third chamber starts to discharge materials. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a high-level box for ensuring stable pulp flow, and solves the problem that the pulp flow in the existing high-level box is not smooth enough.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: A high-level box for ensuring stable pulp flow includes a high-level box main body and a mounting rack fixed on the high-level box main body. The interior of the high-level box main body is divided into three material chambers by two left and right partition plates. Feeding mechanisms are arranged above the two right material chambers. The feeding mechanism includes:

[0007] A material stabilizing component for reducing the impact force when the pulp is fed. The material stabilizing component includes a hydraulic cylinder, which is fixedly connected to the top of the high-level box main body. The telescopic end of the hydraulic cylinder extends into the interior of the high-level box main body, and the telescopic end is fixedly connected with a double-rod bracket. Feeding plates are rotatably connected to both rods of the double-rod bracket, and a damper and a buffer spring for reducing the impact force are arranged between the double-rod bracket and the feeding plates.

[0008] An exhaust component is arranged on the feeding plate for discharging the gas in the pulp.

[0009] Preferably, the damper is rotationally connected between the double-rod bracket and the blanking plate through a rotating connecting piece, and the buffer spring is sleeved outside the damper. Guide plates are fixedly connected above the right sides of the left and right partitions respectively. An infrared distance sensor in a horizontal position is arranged below the blanking plate.

[0010] Preferably, the exhaust assembly includes a plurality of material grooves equidistantly opened on the upper surface of the blanking plate, and chutes penetrating the blanking plate are opened at the bottoms of the inner walls of the plurality of material grooves. A multi-link frame is slidably connected inside each of the plurality of chutes, and the multi-link frame is located below the blanking plate.

[0011] Preferably, one ends of the multiple rods of the multi-link frame located inside the plurality of chutes are fixedly connected with sliding plates. The upper surface of the sliding plate is provided with two rows of baffle blocks in the front and back, and each baffle block is inclined.

[0012] Preferably, two baffles are fixedly connected to the bottom of the blanking plate. T-shaped sliding rods are slidably connected to the right sides of the two baffles.

[0014] Beneficial Effects

[0015] The utility model provides a headbox for ensuring stable pulp flow. Compared with the prior art, the following beneficial effects are achieved:

[0016] 1. For the headbox for ensuring stable pulp flow, the stabilizing component includes a hydraulic cylinder. The hydraulic cylinder is fixedly connected to the top of the headbox main body, and the telescopic end of the hydraulic cylinder extends into the headbox main body. When the pulp flows into the bin, the impact force of the pulp falling is reduced through the design of the stabilizing component. At the same time, the height change of the blanking plate makes the falling height of the pulp not too high, thereby avoiding the problem of pulp fluctuation caused by the falling of the pulp, and improving the stability of the pulp flow in the headbox.

[0017] 2. For the headbox for ensuring stable pulp flow, the exhaust assembly includes a plurality of material grooves equidistantly opened on the upper surface of the blanking plate, and chutes penetrating the blanking plate are opened at the bottoms of the inner walls of the plurality of material grooves. A multi-link frame is slidably connected inside each of the plurality of chutes.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] The high-level tank for ensuring stable pulp flow provides two technical solutions:

[0025] Such as Figures 1-3 shows the first implementation manner: including the high-level tank main body 1 and the mounting frame 2 fixed on the high-level tank main body 1. The inside of the high-level tank main body 1 is divided into three bins by two partition boards 3 on the left and right. Feeding mechanisms are arranged above the two bins on the right. The feeding mechanism includes:

[0026] The material stabilizing assembly 4 is used to reduce the impact force when the slurry is discharged. The material stabilizing assembly 4 includes a hydraulic cylinder 41, which is fixedly connected to the top of the high-level tank body 1. The telescopic end of the hydraulic cylinder 41 extends into the interior of the high-level tank body 1, and a double-rod bracket 42 is fixedly connected to the telescopic end. On both rods of the double-rod bracket 42, a blanking plate 43 is rotatably connected. Between the double-rod bracket 42 and the blanking plate 43, a damper 44 and a buffer spring 45 for reducing the impact force are provided. The damper 44 is rotatably connected between the double-rod bracket 42 and the blanking plate 43 through a rotating connector, and the buffer spring 45 is sleeved outside the damper 44. Above the right sides of the left and right two partition plates 3, a guide plate 46 is fixedly connected. Below the blanking plate 43, an infrared distance sensor 47 in a horizontal position is provided.

[0027] When the slurry flows into the bin, through the design of the material stabilizing assembly 4, the impact force when the slurry falls is reduced. At the same time, by changing the height of the blanking plate 43, the height of the slurry falling will not be too high, thereby avoiding the problem of slurry fluctuation caused by the falling of the slurry, and improving the stability of the slurry flow in the high-level tank.

[0028] As Figure 3 And 4 The second embodiment is shown. The main difference from the first embodiment is that an exhaust assembly 5 is provided on the blanking plate 43 for discharging the gas in the slurry. The exhaust assembly 5 includes a plurality of material grooves 51 equidistantly opened on the upper surface of the blanking plate 43. At the bottom of the inner walls of the plurality of material grooves 51, sliding grooves 52 penetrating the blanking plate 43 are opened. Inside the plurality of sliding grooves 52, a multi-link frame 53 is slidably connected, and the multi-link frame 53 is located below the blanking plate 43. At one end of the multiple rods of the multi-link frame 53 located inside the plurality of sliding grooves 52, a sliding plate 54 is fixedly connected. On the upper surface of the sliding plate 54, two rows of front and rear baffle blocks 55 are provided, and each baffle block 55 is inclined. At the bottom of the blanking plate 43, two front and rear baffle plates 56 are fixedly connected. On the right sides of the two baffle plates 56, a T-shaped sliding rod 57 is slidably connected, and the T-shaped sliding rod 57 penetrates the baffle plate 56 and extends to the left end of the baffle plate 56 and is fixedly connected to the right side of the multi-link frame 53. A return spring 58 is fixedly connected between the end of the T-shaped sliding rod 57 and the baffle plate 56, and the return spring 58 is sleeved outside the T-shaped sliding rod 57. At the bottom of the blanking plate 43, a driving motor 59 is fixedly connected. The output end of the driving motor 59 is fixedly connected with a cam 510, and the cam 510 is in contact with the multi-link frame 53.

[0029] When the slurry falls into the blanking plate 43, the slurry is dispersed by the reciprocating movement of the baffle blocks 55, so that the bubbles in the slurry are broken and the gas therein is discharged, effectively avoiding the problem of bubbles existing in the slurry.

[0030] During use, when the slurry starts to fall into the intermediate bin, the blanking plate 43 is at the lowest position. Then the slurry falls onto the blanking plate 43 under the guidance of the material guiding plate 46. The impact force of the falling slurry is reduced through the cooperation of the damper 44 and the buffer spring 45. The infrared distance sensor 47 detects the distance between the liquid level height and the blanking plate 43. Then, as the slurry liquid level rises, the hydraulic cylinder 41 works to move the blanking plate 43 upward and continuously enhances the effect of reducing the impact force. Additionally, when the slurry falls onto the blanking plate 43, the driving motor 59 starts to rotate the cam 510. The cam 510 rotates and pushes the multi-link frame 53 to move. The movement of the multi-link frame 53 drives the T-shaped slide bar 57 to move and stretches the return spring 58. Then, as the cam 510 continuously rotates, the multi-link frame 53 reciprocates, thereby driving the slide plate 54 to reciprocate. When the slurry is in the material trough 51, the baffle block 55 reciprocates to disperse the slurry and break the bubbles therein. When the slurry in the intermediate bin is full, the blanking mechanism stops working. When discharging from the rightmost bin, the blanking mechanism continues to work.
