Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-4, a dosing unit for dispersant for papermaking, includes storage tank 1, storage tank 1 connects feed arrangement through unloading pipe 2, feed arrangement include inlet pipe 3, locate in inlet pipe 3 and have helical blade's first pivot 4, output with first pivot 4 fixed connection's motor 5, the export of inlet pipe 3 is located inside mixing chamber 6, be equipped with the shutoff board 7 that is used for the export of shutoff inlet pipe 3 in the mixing chamber 6. The motor 5 drives the first rotating shaft 4 to rotate, the helical blade on the first rotating shaft 4 rotates along with the first rotating shaft 4 to convey solid materials to the outlet end of the feeding pipe 3 to enter the mixing chamber 6, the amount of the materials which are pushed forward by a circle of the helical blade with fixed size is fixed, and therefore quantitative proportioning can be carried out by controlling the rotating speed and the rotating time of the motor 5. In some embodiments of the present invention, the storage tanks 1, the discharging pipes 2, and the feeding devices are respectively configured into multiple groups (not less than 2 groups), multiple different raw materials are respectively added into different storage tanks 1, and the adding proportions of the different raw materials are controlled by setting the rotation speed and rotation time of the corresponding motor 5, so as to simultaneously blend the multiple raw materials in proportion. The effect of shutoff board 7 is the export of shutoff inlet pipe 3, seals the export of inlet pipe 3 after the batching is accomplished, avoids external environment to influence the raw materials in the inlet pipe 3 and leads to the raw materials rotten.

Fixedly connected with second pivot 8 is gone up to shutoff board 7, second pivot 8 pass through the bearing with lateral wall A and the lateral wall B of mixing chamber 6 are connected, shutoff board 7 with be equipped with torsional spring 9 between 6 top end faces of mixing chamber, preferably, the position that 6 tops of mixing chamber are close to shutoff board 7 (the upper right corner of shutoff board in figure 1) is equipped with a fixed axle 91 that is on a parallel with second pivot 8, and torsional spring 9 cover is established on fixed axle 91, and one end torque arm is fixed on mixing chamber 6 interior top surface, can the lug connection on 6 top surfaces of mixing chamber, and other end torque arm is contradicted on shutoff board 7, the one end of second pivot 8 runs through lateral wall B stretches out mixing chamber 6 outside and fixedly connected with handle 10, be equipped with the fixing device of fixed handle 10 on the lateral wall B. Torsional spring 9 makes shutoff board 7 shutoff under normal condition on the export of inlet pipe 3 to it is sealed good, when needs batching, rotatory handle 10 makes second pivot 8 rotatory according to the anticlockwise, drives shutoff board 7 rotatory according to the anticlockwise, and the export of inlet pipe 3 is opened the back and is fixed handle 10 through fixing device, avoids shutoff board 7 to reset under the effect of torsional spring 9, makes the export of inlet pipe 3 all be in the open mode (as shown in figure 4) at whole batching in-process.

Fixing device includes pin 11, stopper 12, connecting block 13, spring 14 and runs through lateral wall B's through-hole, pin 11 passes the through-hole, one end are located mixing chamber 6 inside, and the other end is located mixing chamber 6 outside, stopper 12 with pin 11 is located mixing chamber 6 outside one end fixed connection, stopper 12 is thin disc, and stopper 12's diameter is greater than the diameter of through-hole prevents that fixed establishment from getting into mixing chamber 6 completely inside, connecting block 13 with pin 11 is located mixing chamber 6 inside one end fixed connection, spring 14 is located mixing chamber 6 and the cover is established on pin 11, spring 14 one end with connecting block 13 fixed connection, the other end with lateral wall B's internal surface fixed connection. The spring 14 is a tension spring, when the spring 14 is not subjected to external force, the stop lever 11 extends out of the mixing chamber 6 to prevent the handle 10 from rotating, when the plugging plate 7 needs to be opened and fixed, the limit block 12 is pressed along the length direction of the stop lever 11, the stop lever 11 and the connecting block 13 move towards the inner direction of the mixing chamber 6 along with the stop lever 11, the spring 14 is stretched, the handle 10 is rotated to enable the plugging plate 7 to rotate anticlockwise, after the plugging plate 7 is opened, the limit block 12 is released, under the action of the restoring force of the spring 14, the connecting block 13, the stop lever 11 and the limit block 12 recover to the original position, the handle 10 is released, the stop lever 11 can fix the handle 10 to enable the plugging plate 7 to keep the opened state, after batching is completed, the handle 10 is rotated anticlockwise to enable the handle 10 to separate from the stop lever 11, the limit block of the stop lever 11 is pressed, the handle 10 is released, the plugging plate 7 recovers to the closed state under the action of the torsion spring 9, in order to ensure that the plugging plate 7 can recover to the original position smoothly and keep good sealing, the torsion spring 9 is provided in plurality, and may be 3, 4, etc.

As shown in fig. 2, a distance H between an end surface of the stop lever 11 close to the side of the limit block 12 and an end surface of the connecting block 13 far away from the stop lever 11 is smaller than a distance H between an outer surface of the side wall B and the blocking plate 7. When the limiting block 12 is pressed to the outer surface of the side wall B, the connecting block 13 and the stop lever 11 cannot block the rotation of the blocking baffle 7.
