Description

Technical Field

[0001] The utility model relates to the technical field of waste paper pulp, in particular to an iron removal device for waste paper pulp. Background Art

[0002] In order to prevent environmental pollution caused by waste paper, the most commonly used method for dealing with waste paper resources is to make it into recycled paper. The production method of recycled paper mainly turns waste paper into usable pulp, and then recycles the waste paper according to conventional papermaking technology.

[0003] Since waste paper pulp contains a large amount of impurities such as iron impurities, stones, sand, etc., these impurities in the pulp need to be filtered out through an iron removal device before it is turned into usable pulp.

[0004] Iron impurities have great recycling value. Workers often place magnetic bars in the iron removal device to remove iron impurities and achieve the purpose of recycling. However, due to the viscosity of the pulp, this method can easily lead to incomplete adsorption of iron impurities, reducing the quality of iron removal, and the magnetic bars are not easy to clean inside the iron removal device, affecting the subsequent use effect. Utility Model Content

It should be noted that the stirring rod 11 and the pulp iron removal tank 2 are in the same vertical plane, and the stirring rod 11 is driven by the lifting mechanism 8 to fully stir the pulp iron removal tank 2 to improve the iron removal quality.

[0036] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a control valve is provided at the bottom of the pulp deironing tank 2, and the control valve is used to control the discharge of the deironing pulp from the pulp deironing tank 2. It should be noted that the control valve is a prior art technology, and its use method adopts the prior art in this field, so it is not elaborated in detail.

[0037] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the lifting mechanism 8 includes a support plate 801 fixed on the surface of the mounting plate 5, a fixing plate 802 is fixed to the end of the support plate 801, a first motor 803 is fixed to the top of the fixing plate 802, and the output end of the first motor 803 is fixedly connected to a worm 804 via a coupling. It should be noted that the coupling is a technology in the prior art, so it is not described in detail. A worm wheel 805 is meshed at the end of the worm 804, a rotating rod 806 is fixed in the middle of the worm wheel 805, and a gear 807 is fixedly sleeved on the outside of the rotating rod 806, and the gear 807 is meshed with the toothed plate 7.

[0038] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the rotating rod 806 is rotatably connected to the supporting plate 801 .

[0039] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the end of the magnetic rod 12 is connected to a connecting ring 1201, and the interior of the connecting ring 1201 is slidably connected to a control rod 1202. An insertion rod 1203 is fixed to the end of the control rod 1202. Two insertion rods 1203 are provided, and a spring 1204 is fixedly sleeved between the two insertion rods 1203.

[0040] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, slots 1101 for plugging with the inserting rod 1203 are provided on both sides of the stirring rod 11 .

[0041] It should be noted that the specific model specifications of the first motor 803 and the second motor 9 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0042] The use method and advantages of the utility model: When the iron removal device for waste paper pulp is working, the working process is as follows:

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the waste paper pulp to be deironed is poured into the pulp deironing tank 2, and the first motor 803 is started to drive the coupling to drive the worm 804 to rotate. When the worm 804 rotates, it meshes with the worm wheel 805. The worm wheel 805 is forced to rotate and drives the rotating rod 806 to rotate in the support plate 801. When the rotating rod 806 rotates, the gear 807 sleeved on its outside rotates and meshes with the tooth plate 7. The tooth plate 7 is forced to move in the groove of the mounting plate 5. At the same time, the limiting grooves 701 at both ends of the tooth plate 7 slide along the limiting rod 6, so that the tooth plate 7 drives the stirring rod 11 at the bottom to slide down and embed into the pulp deironing tank 2, and the second motor 9 is started to drive the stirring rod 11 to rotate. The centrifugal force is generated by the rotation of the stirring rod 11, so that the waste paper pulp is fully in contact with the magnetic rod 12 in the stirring rod 11, and then the iron filings impurities in the waste paper pulp are attached to the outer wall of the stirring rod 11 through the magnetism generated by the magnetic rod 12 to achieve the effect of effective deironing, thereby achieving the effect of uniform and comprehensive deironing, and improving the deironing quality;

[0044] The waste paper pulp after iron removal is discharged through the discharge pipe 3. When cleaning the magnetic rod, the above steps are performed in reverse so that the tooth plate 7 drives the stirring rod 11 to rise and disengage from the waste paper pulp. Then the staff manually presses the two control rods 1202, and the two control rods 1202 immediately drive the insertion rod 1203 to slide inward and squeeze the spring 1204. The spring 1204 is forced to shrink and drive the insertion rod 1203 to disengage from the slots 1101 on both sides of the stirring rod 11 to release the limit, and pull the connecting ring 1201 to drive the magnetic rod 12 to disengage from the stirring rod 11. As the magnetic rod 12 is pulled out, the magnetic force on the surface of the stirring rod 11 is eliminated, and the iron impurities fall off, thereby achieving the effect of rapid cleaning, reducing the cleaning time, and improving work efficiency.

[0045] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
