Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of metal smelting equipment, and particularly relates to a pumping device and a smelting system. BACKGROUND
[0002] At present, metal smelting technologies mainly include fire smelting and wet smelting. The wet smelting has the advantages of environmental friendliness, high economic benefits and wide application range, and thus becomes a mainstream smelting process in the smelting industry at home and abroad.

In this way, the slurry can be delivered to the downstream first, avoiding the blockage of the filter box by the subsequent more insoluble impurities, thereby improving the delivery rate of the slurry.

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0028] In one aspect, the present application provides a pumping device which can be applied to the conveying or transferring of raw materials (liquid materials or slurry) in a wet smelting process, and the pumping device can avoid the influence of insoluble impurities on the normal operation of the pump and avoid the damage of the pump during conveying of the raw materials.
[0029] In one embodiment, as Figure 1As shown, the pumping device comprises a reaction tank 110, a filter tank 120, a first discharge assembly 130, a second discharge assembly 140 and a delivery pump 150.
[0030] The reaction tank 110 is provided with a first discharge port and a second discharge port, the horizontal height of the first discharge port is higher than that of the second discharge port, and both the first discharge port and the second discharge port can be used for output of raw materials in the reaction tank 110.
[0031] The filter tank 120 is arranged at the downstream side of the reaction tank 110, the first discharge assembly 130 and the second discharge assembly 140 are both connected with the reaction tank 110 and the filter tank 120, and the first discharge assembly 130 is in communication with the first discharge port, and the second discharge assembly 140 is in communication with the second discharge port. The delivery pump 150 is connected with the filter tank 120 to guide the raw materials in the reaction tank 110 to enter the filter tank 120 for filtration, and after the filtration is completed, the filtered slurry is delivered to the downstream by the delivery pump 150.
[0032] Among them, the first discharge assembly 130 and the second discharge assembly 140 are both configured to be operable to open and block the reaction tank 110 and the filter tank 120. In this way, when the reaction of the raw materials in the reaction tank 110 is carried out, the raw materials can be prevented from being discharged by blocking the reaction tank 110 and the filter tank 120.
[0033] By using the above pumping device, the raw materials in the reaction tank 110 first enter the filter tank 120, and after being filtered by the filter tank 120, the slurry is delivered to the downstream by the delivery pump 150. Since the filter tank 120 filters out the insoluble impurities with large particle size, it can effectively prevent the insoluble impurities from affecting the normal use of the delivery pump 150, thereby avoiding damage to the delivery pump 150 and improving the reliability of the device in use.
[0034] At the same time, by providing the first discharge port and the second discharge port with different horizontal heights, in the early stage, the reaction tank 110 and the filter tank 120 can be opened by the first discharge assembly 130, and the reaction tank 110 and the filter tank 120 can be blocked by the second discharge assembly 140. At this time, the slurry in the upper layer of the raw materials in the reaction tank 110 is output to the filter tank 120 through the upper first discharge port; after the slurry in the upper layer is discharged, the reaction tank 110 and the filter tank 120 can be opened by the second discharge assembly 140, and the raw materials containing more insoluble impurities in the lower layer are output to the filter tank 120 through the second discharge port. In this way, the slurry can be delivered to the downstream first, so as to avoid the subsequent more insoluble impurities from blocking the filter tank 120 and affecting the delivery rate of the slurry, thereby improving the delivery rate of the slurry.
[0035] In addition, if the insoluble impurities in the raw material are relatively more, in the process of conveying the raw material to the filter box 120, the first discharge assembly 130 can be used to connect the reaction tank 110 and the filter box 120, while the second discharge assembly 140 keeps the state of isolating the reaction tank 110 and the filter box 120, so as to leave the insoluble impurities in the reaction tank 110, thereby realizing the separation of the slurry and the insoluble impurities. If the insoluble impurities in the raw material are relatively less, the first discharge assembly 130 and the second discharge assembly 140 can be used to connect the reaction tank 110 and the filter box 120 at the same time, so as to improve the conveying rate of the raw material.
[0036] It should be explained that in the reaction tank 110, the insoluble impurities are accumulated at the bottom of the reaction tank 110, and the middle and upper layers are usually the slurry, so the slurry can be input into the filter box 120 through the upper first discharge port; and then the raw material at the lower layer is input into the filter box 120 through the second discharge port, so as to convey the raw material to the downstream as much as possible.
[0037] As an example, the first discharge port and the second discharge port are both located on the side wall of the reaction tank 110, and preferably on the same side. Of course, in other embodiments, the second discharge port can be located on the bottom wall of the reaction tank 110, which is not limited here.
[0038] In an embodiment, the first discharge assembly 130 includes a first discharge valve and a first discharge pipe. The first discharge valve is connected with the reaction tank 110 and communicates with the first discharge port; one end of the first discharge pipe is connected with the first discharge valve, and the other end is connected with the filter box 120. In this way, the first discharge valve can be used to open and close the first discharge port, so as to connect and isolate the reaction tank 110 and the filter box 120. It can be determined that in other embodiments, the first discharge valve can also be arranged on the first discharge pipe or at the filter box 120, which is not limited here.
[0039] In an embodiment, the second discharge assembly 140 includes a second discharge valve and a second discharge pipe. The second discharge valve is connected with the reaction tank 110 and communicates with the second discharge port; one end of the second discharge pipe is connected with the second discharge valve, and the other end is connected with the filter box 120. In this way, the second discharge valve can be used to open and close the second discharge port, so as to connect and isolate the reaction tank 110 and the filter box 120. It can be known that in other embodiments, the second discharge valve can also be arranged on the second discharge pipe or at the filter box 120, which is not limited here. If not specified below, the second discharge valve is connected with the reaction tank 110.
[0040] In one embodiment, the second discharging assembly 140 is detachably connected with the reaction tank 110. After the raw material is input into the filter box 120, the second discharging assembly 140 can be separated from the filter box 120, and the end of the second discharging assembly 140 away from the reaction tank 110 is placed at a preset position, so as to discharge the impurities remaining in the reaction tank 110. It should be noted that in the present embodiment, a control valve can be additionally arranged at the filter box 120, that is, the end of the second discharging pipe away from the second discharging valve is detachably connected with the control valve. When the second discharging pipe is connected with the control valve, the control valve can be opened, so that the raw material can be input into the filter box 120 through the second discharging pipe; after the second discharging pipe is separated from the control valve, the control valve can be closed, so as to prevent the substances in the filter box 120 from flowing out.
[0041] In addition, it can be understood in combination with the above description that, if there are many insoluble impurities in the reaction tank 110, the first discharging valve can be opened, and the second discharging valve can be closed during the process of conveying the raw material to the filter box 120, so as to leave the insoluble impurities in the reaction tank 110, thereby realizing the separation of the slurry and the insoluble impurities; subsequently, the second discharging pipe is separated from the filter box 120, the second discharging valve is opened, and the insoluble impurities are discharged to a preset position through the second discharging pipe.
[0042] In one embodiment, the filter box 120 is provided with a filter 121, and the filter 121 can separate the space in the filter box 120 into a filtering space and a discharging space 122. The first discharging assembly 130 and the second discharging assembly 140 are both in communication with the filtering space, so as to input the raw material into the filtering space; and the conveying pump 150 is in communication with the discharging space 122, so as to pump the slurry filtered by the filter 121 to the downstream. Specifically Figure 1 In the embodiment shown in the figure, the first discharging assembly 130 and the second discharging assembly 140 are connected with the same side of the filter box 120, the filter 121 and the inner wall of the filter box 120 enclose the filtering space, and the filter 121 is arranged in a spaced manner with the bottom wall inside the filter box 120, so as to increase the area of the filter 121, thereby increasing the filtering area and improving the filtering efficiency.
[0043] Further, the bottom of the filter box 120 is also provided with a blowdown port 123, which is in communication with the discharging space 122, so as to facilitate the discharge of the substances remaining at the bottom of the filter box 120. It should be noted that the filtering particle size of the filter box 120 is determined by the pore size of the filter holes on the filter 121, and the impurities with a particle size smaller than the pore size of the filter holes can still enter the discharging space 122 through the filter 121; at the same time, since the conveying pump 150 is connected with the side wall of the filter box 120 and is away from the bottom wall of the discharging space 122, there will be some residues at the bottom of the discharging space 122, which can be discharged through the blowdown port 123 located at the bottom wall. It can be determined that a valve can also be arranged at the blowdown port 123 to control the opening and closing thereof.
[0044] In one embodiment, the filter 121 is detachably connected to the filter box 120, so that when the filter 121 is blocked by too many insoluble impurities, the filter 121 can be detached and cleaned, thereby prolonging the service life of the pumping device and ensuring the filtering efficiency.
[0045] In one embodiment, the filter box 120 comprises a box body and a cover body, the first discharge assembly 130, the second discharge assembly 140 and the delivery pump 150 are connected to the box body, and the cover body is arranged on the top of the box body and is made of transparent material, such as transparent PVC (Polyvinyl chloride), so as to facilitate the operator to observe the blocking condition of the filter 121 in the filter box 120, thereby determining whether the filter 121 needs to be cleaned according to the blocking condition.
[0046] In one embodiment, the pumping device further comprises a discharge pipe 160, which is connected to the filter box 120 and communicates with the discharge space 122; and the delivery pump 150 is connected to the discharge pipe 160, so as to guide the filtered slurry in the filter box 120 to be discharged from the discharge pipe 160.
[0047] In summary, the pumping device in the above embodiment has at least the following advantages:
[0048] 1. The raw material is first filtered and then input into the delivery pump 150, which can avoid the influence of insoluble impurities on the normal operation of the delivery pump 150, avoid damage to the delivery pump 150, prolong the service life, and improve the safety of use;
[0049] 2. The first discharge port and the second discharge port are arranged, the middle and upper layer slurry can be discharged through the first discharge port, and the lower layer of more insoluble impurities is left in the reaction tank 110, which is then discharged to a predetermined position through the second discharge pipe, so as to realize the separation of the slurry and the insoluble impurities, and discharge the residues in the reaction tank 110, thereby achieving the purpose of cleaning;
[0050] 3. In the case of less insoluble impurities, the first discharge port and the second discharge port can be opened to improve the conveying rate of the raw material;
[0051] 4. The filter 121 is detachably arranged, and the blocking condition can be observed through the transparent cover body, thereby prolonging the service life of the filter 121 and ensuring the filtering rate of the slurry.
[0052] On the other hand, the application also provides a smelting system comprising the pumping device in the above embodiment. It can be understood that the smelting system can be applied to the wet smelting process.
[0053] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary and that changes can be made in detail without departing from the principles and spirit of the application. The scope of the application is therefore defined by the appended claims and their equivalents.
