Description

Technical Field

[0001] The utility model relates to the field of cobalt carbonate production, in particular to a novel device for intercepting cobalt carbonate scarring materials. Background Art

[0002] Cobalt carbonate is an important chemical raw material used to prepare various cobalt salts, pigments, magnetic materials and other chemical products. Synthetic reactors are usually used to carry out the synthesis reaction of cobalt carbonate. In the process of producing cobalt carbonate, the synthetic reactor continues to react, causing some cobalt carbonate particles to adhere to the reactor wall and the stirring paddle. As the production continues, this part will stick to form a scab material, and then fall off at a certain point, and go to the washing process together with the cobalt carbonate slurry after the synthesis. Since they are all cobalt carbonates with the same composition, they cannot be removed well in the washing stage. The scab material is solid, hard, and unevenly granulated cobalt carbonate. The scab material mixed in the finished cobalt carbonate will lead to uneven distribution of cobalt carbonate particle size, and large crystals will appear under the electron microscope, which will eventually affect the quality and performance of the cobalt carbonate product, such as irregular particles after calcination into cobalt oxide, or large solid cobalt flakes when reduced to cobalt powder.

[0003] The utility model patent with authorization announcement number CN201333344Y discloses a device for filtering scars in liquid transported in a filtering pipeline, including a feed inlet, a filter box and a discharge port. A movable filter plate is provided in the filter box. Filtration is performed through the filter holes on one side of the filter plate, but filtering can only be performed through one side, and the filtration efficiency is low. In addition, when filtering is performed using a movable filter plate, when too much scars accumulate and block the filter plate, it is troublesome to disassemble for replacement or cleaning.

[0004] The utility model patent with authorization announcement number CN207575896 discloses a new scarring box for the dissolution process of alumina production, including a scarring box body, a feed port, a discharge port, a filter screen, a valve assembly, a cleaning box, a high-pressure water pump, a baffle plate socket, a support plate, a cleaning pipe, a first cleaning port, a second cleaning port, a third cleaning port and a baffle plate. It only filters through one side of the filter screen, and the filtration efficiency is low. When the scarring accumulates too much and blocks the filter screen, although the filter screen does not need to be taken out and can be directly cleaned with a high-pressure water pump, it is necessary to set up cleaning-related structures and discharge ports and corresponding valves. Moreover, cleaning through the cleaning port is prone to dead corners and cannot be completely cleaned. Therefore, it is of certain significance in production to find an interception device with simple structure, high filtration efficiency and easy disassembly of the filtration structure.

[0007] In particular, the interception body also includes an anti-overflow groove, which is arranged on the side wall of the inner tank body or the outer tank body. When the filter screen and the through hole are blocked, the anti-overflow groove can prevent the slurry from overflowing. In addition, the filter screen can be judged to be blocked by the overflow of the slurry into the anti-overflow groove, so as to clean or replace the filter screen in time.

[0008] In particular, the anti-fleeting slot is opened at a position 5 cm higher than the highest through hole to prevent the slurry coming out of the filter holes of the interception filter from splashing onto the anti-fleeting slot, or to prevent the scarred material from rushing into the anti-fleeting slot due to feeding, resulting in erroneous judgment that the filter is blocked.

[0009] In particular, the feeding mechanism includes a straight feed pipe, a feed tee, a first valve, a second valve and a bridge elbow, wherein the straight feed pipe and the bridge elbow are welded to the feed tee, the bridge elbow extends into the inner tank body, one end of the feed tee leading to the bridge elbow is connected to the first valve, and the end leading to the washing tank is connected to the second valve.

[0010] In particular, the discharging mechanism includes a low-level discharging pipe, a high-level anti-bubbling trough pipe, a discharging tee and a discharging straight pipe.

[0011] In particular, the high-level anti-bubble trough pipeline is a transparent pipeline, and the staff can quickly determine whether the filter is blocked by visually observing the discharge of the high-level anti-bubble trough pipeline.

[0012] In particular, the length, width and height of the outer trough body are all 1.2m, and the length, width and height of the inner trough body are all 1m. The volume of the outer trough body is slightly larger than that of the inner trough body, so that when the anti-overflow groove is set on the side wall of the outer trough body, when the filter screen and the through hole are blocked, the excess slurry can overflow from the anti-overflow groove of the outer trough body in time, thereby better intercepting the scar material.

[0013] Particularly, the through holes on the inner tank body have a diameter of 4 cm, and the through holes form rectangular through hole arrays on the four side walls. Each rectangular through hole array has 10 rows, and each row has 15 through holes. The through holes are spaced 1 cm up and down and left and right, which is neat and beautiful.

[0014] In particular, the interception filter is in the shape of a net bag, the mesh size of the interception filter ranges from 80 to 200 meshes, and the material is nylon or stainless steel.

[0015] The utility model has the advantages of simple structure, low cost and high filtering efficiency. The intercepting filter screen arranged on the inner tank body can quickly filter out the scarring material.

DETAILED DESCRIPTION

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0025] Reference Figure 1 and Figure 2 , which is the first embodiment of the utility model, and provides a new device for intercepting cobalt carbonate scarring material, including a feeding mechanism 1, an intercepting body 2, and a discharging mechanism 3. The intercepting body 2 is composed of an outer tank body 21, an inner tank body 22, and an intercepting filter screen 23. The feeding mechanism 1 extends into the inner tank body 22 for feeding, and the discharging mechanism 3 is connected to the intercepting body 2 for discharging. The top of the inner tank body 22 is open, and the inner tank body 22 is placed in the outer tank body 21. A plurality of through holes are provided on the four side walls of the inner tank body 22. The intercepting filter screen 23 is laid on the inner surface of the inner tank body 22 and covers the through holes. The bottom wall of the outer tank body 21 is provided with a liquid outlet 24. When production continues for a period of time, the intercepting filter screen 23 and the through holes will be blocked by the scarring material, so the staff needs to clean them regularly once a month.

[0026] The interception body 2 also includes an anti-flowing slot 25, which is opened on the side wall of the outer tank body 21 at a position 5 cm higher than the highest through hole of the inner tank body 22. When the interception filter 23 and the through hole are blocked, the anti-flowing slot 25 can be used to discharge the material to prevent the material from spilling. In addition, the slurry overflowing into the anti-flowing slot 25 can be used to judge the blockage of the interception filter 23, so as to clean or replace the interception filter 23 in time. The anti-flowing slot 25 is set at a height of 5 cm to prevent the slurry coming out of the filter hole from splashing to the anti-flowing slot 25, resulting in the wrong judgment that the interception filter 23 is blocked.

[0027] The feeding mechanism 1 includes a feeding straight pipe 11, a feeding tee 12, a first valve 13, a second valve 14 and a bridge elbow 15, wherein the feeding straight pipe 11 and the bridge elbow 15 are welded to the feeding tee 12, the bridge elbow 15 extends into the inner tank body 22, one end of the feeding tee 12 connected to the bridge elbow 15 is connected to the first valve 13, and the end of the feeding tee 12 leading to the washing tank is connected to the second valve 14; when it is necessary to clean the scab material in the interception filter 23 or replace the interception filter 23, close the first valve 13. The door 13 opens the second valve 14 to allow the slurry to be temporarily transported from the bypass to the washing tank, so as to achieve uninterrupted discharging during the production process; the discharging mechanism 3 includes a low-level discharging pipe 31, a high-level anti-floating tank pipe 32, a discharging tee 33 and a discharging straight pipe 34. The high-level anti-floating tank pipe 32 of the discharging mechanism 3 is connected to the anti-floating tank port 25, the low-level discharging pipe 31 is connected to the liquid outlet 24, the low-level discharging pipe 31 and the high-level anti-floating tank pipe 32 are connected by the discharging tee 33, and are directly connected to the washing tank through the discharging straight pipe 34.

[0028] Specifically, the feeding mechanism 1 delivers the cobalt carbonate slurry through a pump.

[0029] Specifically, the apertures of the feed straight pipe 11, the liquid outlet 24 and the anti-flow notch 25 can be selected from DN25 to DN75, and DN25 is selected in this embodiment.

[0030] Specifically, the high-position anti-bubbling trough pipe 32 is a transparent pipe, and the staff can quickly determine whether the interception filter 23 is blocked by directly visually observing the discharge situation of the high-position anti-bubbling trough pipe 32.

[0031] Specifically, the length, width and height of the outer tank body 21 are all 1.2 m, and the length, width and height of the inner tank body 22 are all 1 m. The volume of the outer tank body 21 is slightly larger than that of the inner tank body 22, and the storage space is limited. When the anti-fleeting slot 25 is opened on the outer tank body 21, once the filter screen and the through hole are seriously blocked, the excess slurry overflows from the anti-fleeting slot 25, which promptly alerts the staff to replace or clean the intercepting filter screen 23.

[0032] Specifically, the through holes on the inner tank body 22 have a diameter of 4 cm. The through holes form rectangular through hole arrays on the four side walls. Each rectangular through hole array has 10 rows, and each row has 15 through holes. The through holes are spaced 1 cm up and down and left and right, which is neat and beautiful.

[0033] Specifically, the intercepting filter 23 is in the shape of a net bag, and the mesh size of the intercepting filter 23 ranges from 80 to 200 meshes. In this embodiment, 80 meshes are selected. The material is nylon or stainless steel. Since the intercepting filter 23 is an integrally formed net bag, it is convenient and quick to replace.

[0034] An anti-bubbling notch 25 is set on the outer tank body 21 to ensure that the slurry will not bubble up in the outer tank body 21, thereby avoiding the loss of cobalt carbonate. The cobalt carbonate slurry is transported to the inner tank body 22 by a pump. The flow rate through the pump is high, and the slurry is filtered through the interception filter 23 and flows out of the inner tank body 22. The amount of slurry flowing out of the inner tank body 22 must be less than the amount flowing into the inner tank body 22. Therefore, when the interception filter is not blocked, the liquid level of the inner tank body 22 will also rise slowly; as the amount of filtered slurry increases at the bottom of the interception filter 23, the scar material will block the through holes and the filter holes of the filter, and the liquid level will rise faster; as the area of ​​​​blockage of the interception filter increases, the cobalt carbonate slurry cannot flow, and the cobalt carbonate particles are fine, and when they do not flow, they will adhere to the periphery of the through holes. When this When some particles are deposited in the inner tank body 22, a layer of viscous slurry will be formed; when about half of the through holes of the intercepting filter screen 23 are blocked, the liquid level in the inner tank body 22 will rise rapidly, causing the tank to overflow. However, due to the limited space between the inner and outer tanks and the feed is transported by a pump, the slurry flows out of the liquid outlet 24 naturally. Under the condition of the same aperture, the amount flowing out of the liquid outlet 24 is less than the amount overflowing to the outer tank body 21. Therefore, it will overflow into the anti-overflow slot 25 in a short time. The anti-overflow slot 25 and the liquid outlet 24 are both used for discharging, which will not cause the outer tank body 21 to overflow, and it can also enable the staff to quickly discover abnormalities. Example 2

[0035] Reference Figure 3 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment, with the difference that the anti-fleeting slot 25 is arranged on the side wall of the inner tank body 22 at a position 5 cm higher than the highest through hole, and the high-position anti-fleeting slot pipe 32 of the discharging mechanism 3 passes through the outer tank body 21 to connect to the anti-fleeting slot 25, so as to avoid the scar material from rushing into the anti-fleeting slot 25, resulting in the erroneous judgment of the filter screen being blocked; when the filter screen and the through hole are blocked, the slurry in the inner tank body 22 can overflow to the anti-fleeting slot 25 earlier, and timely feedback can be given to the staff, so as to replace or clean the intercepting filter screen 23.

[0036] Working process of Example 1 and Example 2: During normal operation, the first valve 14 is closed, and the first valve 13 is opened. The cobalt carbonate slurry is transported from the feed straight pipe 11 to the feed tee 12, and then falls into the inner tank body 22 through the bridge elbow 15. The slurry filters out the scab material through the interception filter 23 and enters the outer tank body 21. The filtered slurry enters the low-level discharge pipe 31 through the liquid outlet 24, and then is transported to the discharge tee 33, and finally directly passes through the discharge straight pipe 34 to the washing tank. After continuous production for a period of time, the interception filter 23 will accumulate too much scab material and block it. Plug the filter screen and the holes. At this time, the slurry will flow from the upper edge of the inner tank body 22 to the anti-floating slot 25. Because the high-level anti-floating slot pipe 32 is transparent, it is convenient for personnel to observe. When this phenomenon occurs, open the second feed valve 14, close the first feed valve 13, and let the cobalt carbonate slurry be transported to the washing tank from the bypass. At this time, the intercepting filter screen 23 can be manually and quickly pulled out, the filter screen can be cleaned or replaced with a new one, and then the first valve 13 is opened, the first valve 14 is closed, and the slurry is continued to be filtered. The cobalt carbonate scar material collected from the intercepting filter screen 23 is recycled by dissolving it with hydrochloric acid. Example 3

[0037] As another preferred solution of Examples 1 and 2, the inner tank body 22 is hollow and placed in the outer tank body 21, and the four side walls and the bottom wall of the inner tank body 22 are provided with a plurality of through holes. Compared with the above solution, multiple surfaces filter the scar material, thereby increasing the filtering efficiency.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
