Description

Technical Field

[0001] The present invention relates to the technical field of pulp molding equipment, and in particular to a pulp box for preventing pulp from settling for pulp molding. Background Art

[0002] The pulp box of pulp molding is an important component in the pulp molding process, which is mainly used to contain and process pulp raw materials. The pulp box usually includes a box body, which is provided with a pulp inlet and a pulp overflow port. Slurry is added through the pulp inlet and discharged through the pulp overflow port after reaching a certain liquid level. The slurry introduced into the pulp box contains a large amount of fiber. If it is not stirred, it will gradually settle to the bottom, resulting in too low fiber concentration on the top. The current pulp box uses an air compressor to blow compressed air into the bottom of the box body to make the slurry uniform and prevent the slurry particles from settling. However, this method has a relatively complex structure and high production costs. Utility Model Content

[0025] Example

[0026] like Figure 1-3 As shown, this embodiment provides a slurry box for preventing slurry sedimentation for pulp molding, including a box body 1, the sides of the box body 1 are respectively provided with a slurry inlet 2 and a slurry overflow port 3, the outer side of the slurry inlet 2 is connected to a pipeline for conveying slurry raw materials, the inner side of the slurry inlet 2 is detachably connected to a guide pipe 4, and the two ends of the guide pipe 4 are respectively provided with a plurality of convection ports 43 opposite to each other. The slurry raw material enters the box body 1 through the convection ports 43, and the convection ports 43 opposite to each other at the two ends are arranged to enable the sprayed slurry to generate convection, which can effectively prevent slurry sedimentation and improve the uniformity of the wall thickness of pulp molded products.

[0027] Specifically, the guide tube 4 includes a connecting section 41 and a guide section 42, the middle part of the connecting section 41 is detachably connected to the inner side of the slurry inlet 2, and in this embodiment, the middle part of the connecting section 41 is inserted into the slurry inlet 2 and fixed by a quick-release sleeve, so installation and disassembly are convenient and quick; the two ends of the connecting section 41 respectively extend to the two sides inside the box body 1, and the two ends of the connecting section 41 are respectively detachably connected with the guide section 42, and a plurality of convection ports 43 are opened on the opposite sides of the two guide sections 42, and the positions of the convection ports 43 of the two guide sections 42 are arranged one by one. In this embodiment, the number of convection ports 43 of each guide section 42 is six, and the convection ports 43 of each guide section 42 are equidistant from each other; and in this embodiment, the connection between the guide section 42 and the connecting section 41 is fixed by a quick-release sleeve, so installation and disassembly are convenient and quick. The slurry enters the connecting section 41 through the slurry inlet 2, and then is divided into the guide sections 42 on both sides, and is discharged from the convection port 43 of the guide section 42. After the slurry is discharged, convection is generated to stir the internal slurry, which can effectively prevent the slurry from settling and improve the uniformity of the wall thickness of the pulp molded product.

[0028] The interior of the box body 1 is divided into a slurry inlet area 11 and an overflow area 12 by a partition 51, the slurry inlet 2 and the guide pipe 4 are arranged in the slurry inlet area 11, and the slurry overflow outlet is arranged in the overflow area 12. After the slurry enters the slurry inlet area 11, the liquid level rises to exceed the partition 51 and then enters the overflow area 12, and then is discharged from the slurry overflow outlet.

[0029] Furthermore, a movable plate 52 is included, a fixing hole is provided on the partition plate 51, an adjustment hole 53 is provided on the movable plate 52, an adjustment bolt 54 is provided through the adjustment hole 53, and the adjustment bolt 54 is fixed to the fixing hole by a nut. By loosening the adjustment bolt 54 and the nut, and then moving the movable plate 52, the movable plate 52 is moved to a specified height, and then tightened, so as to change the height of the movable plate 52, so that the total height of the partition plate 51 and the movable plate 52 is changed, thereby changing the liquid level of the slurry inside the box body 1 to adapt to the use of different products.

[0030] Furthermore, there are two overflow ports 3. The overflow speed is increased by the two overflow ports 3 to prevent the overflow speed from being lower than the slurry feeding speed, which causes the liquid level to rise.

[0031] In this embodiment, a sewage outlet 6 is provided at the bottom of the side of the box body 1. There are two sewage outlets 6, which are respectively connected to the slurry inlet area 11 and the overflow area 12. A valve is provided on the sewage outlet 6. The valve on the sewage outlet 6 is a SUS304 ball valve, which can be cleaned and discharged regularly.

[0032] The top of the box body 1 is detachably connected with a plurality of baffles 7. The box body 1 is designed with a detachable structure up and down, and the upper baffle 7 is fixed by bolts, and can be removed for cleaning, so as to facilitate cleaning of the inside of the box body 1.

[0033] Furthermore, the bottom of the baffle 7 extends into the interior of the box body 1, and a sealing strip is provided at the connection between the baffles 7 and the baffles 7, and the sealing strip is fixedly connected to the inner side of one of the baffles 7. In order to prevent the splashed slurry from overflowing from the connection between the baffle 7 and the box body 1, the inner side of the baffle 7 is extended to extend into the interior of the box body 1, so as to cover the gap at the connection and prevent the slurry from leaking out; similarly, a sealing strip is provided at the connection between the baffles 7 and the baffles 7, and the sealing strip is only welded and fixed to one of the baffles 7, so as to cover the gap and will not affect the separation of the two baffles 7.

[0034] Furthermore, one end of the guide section 42 away from the connecting section 41 is fixedly installed in the box body 1 by bolts, thereby improving the structural strength of the guide section 42 and preventing it from falling off due to the impact of internal water flow.

[0035] The working principle of the utility model is as follows: first, the nut on the adjusting bolt 54 is loosened, and then the height of the movable plate 52 is changed. After moving to a suitable height, the nut on the adjusting bolt 54 is tightened to fix it, and the liquid level height inside the box body 1 is controlled. Then, slurry is introduced through the slurry inlet 2 and discharged through the convection port 43. The slurry discharged from the convection ports 43 on both sides impact each other to form convection, which plays a role in stirring the internal slurry, can effectively prevent the slurry from settling, and improve the uniformity of the wall thickness of the pulp molded product. After the work is completed, the internal slurry is discharged by opening the valves of the two sewage outlets 6, and then the partition 51 and the guide pipe 4 are disassembled for cleaning.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them.
