Description

Technical Field

[0001] The present application relates to the technical field of boron carbide recovery, and in particular to a precipitation device. Background Art

[0002] The boron carbide waste liquid after grinding contains a large amount of boron carbide particles. Therefore, a filter press is used to dry the boron carbide waste liquid to separate the boron carbide particles remaining in the boron carbide waste liquid. The waste liquid after filtering by the filter press is then discharged to a sewage station for treatment, thereby realizing the recycling of boron carbide, which is beneficial to saving production costs.

[0003] In the prior art, to improve the recovery rate of boron carbide particles, a large-mesh filter press is used. However, large-mesh filter presses are overloaded during use and are prone to clogging and other problems, thereby reducing the recovery rate of boron carbide particles. To reduce the probability of filter press failure, a small-mesh filter press is used. However, using a small-mesh filter press can result in excessive boron carbide particles remaining in the wastewater from the filter press. Furthermore, the presence of a large amount of boron carbide particles in the wastewater increases the treatment costs of sewage treatment plants.

[0026] In order to clearly illustrate the technical solution of this application, the following is also defined: Figure 1 Front, back, top and bottom shown.

[0027] like Figure 1 and Figure 2As shown, the present application provides a precipitation device 100, which is used for re-precipitation of waste liquid from a filter press. Specifically, the precipitation device 100 includes a device body 11 and a filter plate 12. The device body 11 is used for precipitation of boron carbide particles, and the device body 11 is provided with a liquid inlet 111 and a liquid outlet 112. The liquid inlet 111 is configured to be connected to the waste liquid outlet of the filter press, and the liquid outlet 112 is configured to be able to transport the filtered waste liquid to the outside. The filter plate 12 is fixed in the device body 11, and the filter plate 12 divides the interior of the device body 11 into a filtration area 113 and a precipitation area 114. The filter plate 12 is configured to be able to prevent precipitates in the waste liquid from entering the filtration area 113. Among them, the precipitation area 114 is connected to the liquid inlet 111, and the filtration area 113 is connected to the liquid outlet 112. With this arrangement, waste liquid from the filter press can be precipitated in precipitation area 114, facilitating the separation of boron carbide particles from the waste liquid into boron carbide precipitate. Furthermore, the filter plate 12 prevents the boron carbide precipitate from entering the filtration area 113, facilitating the collection of the boron carbide, thereby increasing the boron carbide recovery rate and reducing production costs.

[0028] Secondly, the above arrangement can also reduce the boron carbide particles in the waste liquid introduced into the sewage treatment station, thereby helping to reduce the treatment costs of the sewage treatment station, and further helping to save the overall treatment costs of the boron carbide waste liquid and further reduce production costs.

[0029] In addition, in the present application, by improving the recovery rate of boron carbide in the waste liquid of the filter press, it is beneficial to improve the overall recovery rate of boron carbide in the ground boron carbide waste liquid. Furthermore, on the premise of improving the overall recovery rate of boron carbide, the mesh size of the filter press can be reduced to reduce the load of the filter press, and then the failure probability of the filter press can be reduced, which is beneficial to reducing the maintenance cost of the filter press.

[0030] In one embodiment, the filter plate 12 is provided with a filter hole 121, which connects the filter area 113 and the sedimentation area 114. The filter hole 121 is configured to prevent sediment in the waste liquid from entering the filter area 113. In this configuration, the filter hole 121 blocks the boron carbide from being precipitated in the sedimentation area 114, thereby preventing the boron carbide precipitate from being lost in the sedimentation area 114, thereby facilitating an improvement in the recovery rate of the boron carbide.

[0031] In this embodiment, the cross-section of the filter holes 121 perpendicular to the vertical direction of the precipitation device 100 is rectangular, and the minimum width of this cross-section is smaller than the minimum width of the boron carbide precipitate in the precipitation area 114. This configuration prevents the boron carbide precipitate from passing through the filter holes 121 and entering the filtration area 113, thereby improving the recovery rate of boron carbide in the filter press wastewater.

[0032] It should be noted that the present application does not impose any restrictions on the shape of the cross section of the filter hole 121 perpendicular to the vertical direction of the precipitation device 100 , as long as the boron carbide precipitate in the precipitation area 114 cannot pass through the filter hole 121 .

[0033] like Figure 2 As shown, as an embodiment, the filter hole 121 extends along the preset straight line 101, defining a horizontal plane 102 perpendicular to the vertical direction of the sedimentation device 100, and the preset straight line 101 is not perpendicular to the horizontal plane 102. Such an arrangement allows the filter hole 121 to be tilted. It can be understood that the tilted filter hole 121 can increase the flow rate of the waste liquid in the filter hole 121, thereby improving the sedimentation efficiency of the sedimentation device 100. In addition, by increasing the flow rate of the waste liquid in the filter hole 121, the waste liquid can flush the inner wall of the filter hole 121, thereby avoiding the blockage of the filter hole 121, which is conducive to improving the flowability of the filter hole 121.

[0034] In one embodiment, a fixing boss 115 is formed at least partially within the device body 11. The fixing boss 115 is located below the filter plate 12 and abuts against the filter plate 12. The fixing boss 115 is configured to support the filter plate 12. This arrangement enables the device body 11 to support the filter plate 12 to prevent the filter plate 12 from falling out of the device body 11, thereby improving the sedimentation stability of the sedimentation device 100.

[0035] It should be noted that in the present application, the gravity of the filter plate 12 itself is greater than the impact force of the waste liquid in the device body 11 on the filter plate 12, thereby preventing the filter plate 12 from falling off the fixed boss 115 after being impacted by the waste liquid, which is beneficial to improving the sedimentation stability of the sedimentation device 100.

[0036] like Figure 3 As shown, as an optional implementation, an elastic member 116 is further disposed within the device body 11. The elastic member 116 is positioned above the fixing boss 115, with the filter plate 12 positioned between the fixing boss 115 and the elastic member 116. The elastic member 116 is configured to cooperate with the fixing boss 115 to secure the filter plate 12. With this arrangement, the fixing boss 115 and the elastic member 116 can limit the upper and lower positions of the filter plate 12 along the vertical direction of the sedimentation device 100, thereby further improving the connection stability of the filter plate 12 within the device body 11. Furthermore, the elastic member 116 has a deformable nature, facilitating assembly and disassembly of the filter plate 12 from the device body 11.

[0037] like Figure 4As shown, as another implementation, a slot 117 is further formed in the device body 11. The filter plate 12 is elastic, and the filter plate 12 is at least partially located in the slot 117 and engaged with the slot 117. With this arrangement, the filter plate 12 and the device body 11 can be connected by the engagement of the slot 117 and the filter plate 12, thereby eliminating the need for additional retaining structures such as the elastic member 116. This helps simplify the structure of the device body 11 and further facilitates the assembly of the filter plate 12 and the device body 11.

[0038] It should be noted that the present application does not impose any restrictions on the connection form between the filter plate 12 and the device body 11 , as long as the supporting force of the device body 11 on the filter plate 12 is greater than the impact force of the waste liquid on the filter plate 12 .

[0039] As an embodiment, the filtration area 113 is located above the sedimentation area 114, and the liquid outlet 112 is located above the liquid inlet 111. Such an arrangement can slow down the flow rate of the filter press waste liquid in the sedimentation area 114, thereby facilitating the precipitation of boron carbide under the action of gravity, thereby improving the recovery rate of boron carbide. In addition, the filter press waste liquid enters the sedimentation area 114 from the lower end, which can reduce the disturbance of the liquid in the sedimentation area 114, thereby avoiding disturbance of the boron carbide precipitate, and further facilitating the improvement of the precipitation efficiency of boron carbide. In addition, it can also prevent the filter press waste liquid from directly passing through the device body 11 without fully contacting the sedimentation area 114, thereby facilitating the improvement of the recovery rate of boron carbide.

[0040] like Figure 2 As shown, as an embodiment, the precipitation device 100 further includes a collection mechanism 13 for collecting boron carbide precipitates within the precipitation device 100. Specifically, the device body 11 is provided with a discharge port 118, which connects the collection mechanism 13 and the precipitation area 114. With this arrangement, the boron carbide precipitates can be discharged into the collection mechanism 13 through the discharge port 118 for collection.

[0041] As an optional implementation, the discharge port 118 is located below the device body 11 along the vertical direction of the precipitation device 100, and the collection mechanism 13 is located below the discharge port 118. In this arrangement, when the discharge port 118 is opened, the boron carbide precipitate will fall downward into the collection mechanism 13 due to gravity, eliminating the need for manual cleaning of the boron carbide precipitate, thereby improving the ease of use of the precipitation device 100.

[0042] In some embodiments, the collection mechanism 13 includes a collection frame 131 and universal wheels 132. Along the vertical direction of the precipitation device 100, the collection frame 131 is located below the discharge port 118, so that the collection frame 131 can collect the boron carbide precipitate discharged from the discharge port 118. The universal wheels 132 are installed below the collection frame 131 to facilitate the movement of the collection frame 131, thereby facilitating the transportation of the boron carbide precipitate.

[0043] As an embodiment, the precipitation device 100 further includes a plurality of partition plates 14, which are fixed below the device body 11 and divide the precipitation area 114 into a plurality of partitions 1141. Specifically, the plurality of partitions 1141 are distributed along the direction from the liquid inlet 111 to the liquid outlet 112, and each partition 1141 is provided with a discharge port 118. This arrangement allows boron carbide in the waste liquid to precipitate within the plurality of partitions 1141, achieving multi-stage precipitation of boron carbide particles, thereby improving the precipitation efficiency of the boron carbide.

[0044] Specifically, when the waste liquid of the filter press enters the sedimentation area 114 from the liquid inlet 111, the large-particle boron carbide particles will be precipitated in the partition 1141 near the liquid inlet 111 due to their own gravity, and the small-particle boron carbide particles will be precipitated in the partition 1141 away from the liquid inlet 111 due to their own gravity. In addition, during the flow of the waste liquid of the filter press, it will sequentially pass through multiple partitions 1141 from the liquid inlet 111 for multi-stage sedimentation, which is beneficial to improving the overall precipitation efficiency of the boron carbide particles in the waste liquid, and further beneficial to improving the recovery rate of boron carbide.

[0045] In this application, the precipitation steps of the precipitation device 100 are as follows:

[0046] First, filter press wastewater is introduced into the settling area 114 of the apparatus body 11 through the liquid inlet 111. Boron carbide particles in the filter press wastewater are precipitated in the settling area 114, thereby separating the boron carbide precipitate from the liquid in the wastewater. The boron carbide particles in the wastewater can undergo multi-stage precipitation within the multiple partitions 1141, thereby improving the settling efficiency of the boron carbide particles in the boron carbide wastewater.

[0047] The precipitated wastewater then enters the filtration area 113 through the filter holes 121. The wastewater in the filtration area 113 is then discharged through the liquid outlet 112 to the sewage treatment station for treatment. At this point, the filter holes 121 can prevent the boron carbide precipitate in the precipitation area 114 from entering the filtration area 113, thereby improving the boron carbide recovery rate of the precipitation device 100. Furthermore, the above steps can reduce the amount of boron carbide particles in the wastewater in the filtration area 113, thereby reducing the treatment costs of the sewage treatment station and ultimately lowering the cost of sewage treatment.

[0048] Finally, the discharge port 118 is opened to allow the collected boron carbide precipitate to fall into the collecting mechanism 13 for collection, thereby realizing the recovery of the boron carbide, which is beneficial to reducing production costs.

[0049] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims appended to this application.
