The feed pipe of the autoclave is usually connected with a feed pump, and the feed pump is used to deliver raw materials to the autoclave. In actual production, the feed pipe needs to be cleaned and maintained regularly to remove the slurry attached to the feed pipe.

[0003] In the prior art, when the feed pipe is flushed, the feed pump needs to be stopped, and raw water is injected from the inlet of the feed pump. The raw water enters the feed pipe through the feed pump for flushing.

[0004] However, when the liquid level of the raw water in the feed pump reaches a certain height, the raw water can enter the feed pipe, which leads to low cleaning efficiency of the feed pipe. CONTENT OF THE INVENTION

[0011] In one possible implementation, further comprising: a control valve arranged on the first flushing pipe to control the opening and closing of the first flushing pipe.

[0012] In a possible implementation, the autoclave is provided with a feed valve configured to control the opening and closing of the feed port, and the feed valve is configured to be closed when the flushing pipe group injects the flushing water into the feed pipe.

[0013] In a possible implementation, the feed port, the feed pump, the working pipe group and the flushing pipe group are all multiple.

[0014] In a possible implementation, the system further comprises a waste discharge pump arranged on the waste discharge pipe and configured to control the opening and closing of the waste discharge pump, and the waste discharge pump is configured to be opened after the first flushing pipe injects the flushing water into the feed pipe for a second preset time length.

These figures and the written description are not to be construed as limiting the scope of the concept of the application in any way, but merely as illustrating the specific embodiments of the application. DETAILED DESCRIPTION

[0038] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description of the exemplary embodiments is intended to apply to all alternative embodiments, as would be understood by one skilled in the art. The following exemplary embodiments are described herein with reference to the figures. In the description of the figures, like numbers refer to like elements throughout. The embodiments described in the following exemplary embodiments are not meant to be limiting of the application. Rather, they are provided as examples of apparatus and methods consistent with some aspects of the application as detailed in the following claims.

[0039] As shown in the background, the feed pipe of the autoclave is usually connected with the feed pump, and the raw material is transported to the autoclave through the feed pump. In actual production, the feed pipe needs to be cleaned and maintained regularly to remove the slurry attached in the feed pipe. In the prior art, when the feed pipe is flushed, the feed pump needs to be stopped, and raw water is injected from the inlet of the feed pump. After the raw water reaches a certain liquid level in the feed pump, it is overflowed from the outlet of the feed pump and then enters the feed pipe for flushing.

[0040] However, when the feed pipe is cleaned in this way, the raw water can enter the feed pipe only when the liquid level of the raw water reaches a certain height in the feed pump, which leads to low cleaning efficiency of the feed pipe.

[0041] To solve the above technical problems, the pipeline cleaning system of the mineral processing equipment and the mineral processing equipment provided by the embodiments of the present application are provided. The pipeline cleaning system of the mineral processing equipment comprises an autoclave, a feed pump, a working pipe group and a flushing pipe group. The working pipe group comprises a feed pipe and a waste pipe. One end of the feed pipe is in communication with the outlet of the feed pump, and the other end is in communication with the feed inlet of the autoclave. One end of the waste pipe is in communication with the feed pipe, and the other end is in communication with a sewage collecting device. The flushing pipe group is at least partially in communication with the feed pipe and can inject flushing water into the feed pipe. When the mineral processing equipment is working normally, the waste pipe is closed with the feed pipe. The raw material to be processed is input from the inlet of the feed pump, and then sequentially passes through the feed pump, the feed pipe and the feed inlet to enter the autoclave for processing. After a certain period of continuous work, part of the slurry in the feed pipe needs to be cleaned. At this time, the feed pump is closed, and the waste pipe is connected with the feed pipe. The flushing pipe group starts to inject flushing water into the feed pipe, and the flushing water is discharged through the waste pipe to clean the feed pipe. Thus, the flushing pipe group of the pipeline cleaning system of the mineral processing equipment provided by the present application can directly inject flushing water into the feed pipe without passing through the feed pump, which is beneficial to save the time for injecting flushing water into the feed pipe. At the same time, the flushing pipe group is directly connected with the feed pipe, which can ensure that the high-pressure flushing water in the flushing pipe maintains a relatively large pressure when entering the feed pipe, and is beneficial to further improve the cleaning efficiency of the feed pipe.

[0042] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail in the specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings:

[0043] It should be noted that the pipeline cleaning system of the mineral processing equipment provided by the embodiments of the present application can be applied to various different mineral processing equipment.

[0044] Reference is made to Figure 1 and Figure 2As shown, the pipeline cleaning system 100 of the mineral processing equipment in the embodiment of the present application comprises: an autoclave 110, a feed pump 120, a working pipe set 130, and a flushing pipe set 140. The autoclave 110 has a feed inlet 111. The feed pump 120 has an inlet 121 and an outlet 122. The working pipe set 130 comprises a feed pipe 131 and a waste pipe 132. The feed pipe 131 is used to connect the outlet 122 and the feed inlet 111. The waste pipe 132 is connected with the feed pipe 131. The flushing pipe set 140 is at least configured to inject flushing water into the feed pipe 131 and discharge the flushing water through the waste pipe 132.

[0045] In the embodiment of the present application, one end of the feed pipe 131 is in communication with the outlet 122 of the feed pump 120, and the other end is in communication with the feed inlet 111 of the autoclave 110. One end of the waste pipe 132 is connected with the feed pipe 131, and the other end is used to communicate with a sewage collection device. The flushing pipe set 140 at least partially communicates with the feed pipe 131 and can inject flushing water into the feed pipe 131. When the mineral processing equipment is normally working, the waste pipe 132 is closed with the feed pipe 131. The raw material to be processed is input from the inlet 121 of the feed pump 120, sequentially passes through the feed pump 120, the feed pipe 131, and the feed inlet 111, and then enters the autoclave 110 for processing. After working for a certain period of time, part of the slurry in the feed pipe 131 needs to be cleaned.

[0046] In the prior art, the main method for cleaning the feed pipe 131 is to stop the feed pump 120, and then inject flushing water from the inlet 121 of the feed pump 120. When the water level of the flushing water in the feed pump 120 is higher than the outlet 122 of the feed pump 120, the flushing water enters the feed pipe 131 from the feed pump 120 to flush the feed pipe 131. However, this requires the flushing water to accumulate in the feed pump 120 for a period of time before entering the feed pipe 131. In the embodiment of the present application, when the pipeline cleaning system 100 of the mineral processing equipment starts cleaning, the feed pump 120 is closed, and the waste pipe 132 is communicated with the feed pipe 131. Then, the flushing pipe set 140 directly injects flushing water into the feed pipe 131, and the flushing water is discharged through the waste pipe 132 to clean the feed pipe 131. Thus, the flushing pipe set 140 of the pipeline cleaning system 100 of the mineral processing equipment provided by the present application can directly inject flushing water into the feed pipe 131 without passing through the feed pump 120, which is beneficial to save the time for injecting flushing water into the feed pipe 131. Meanwhile, the flushing pipe set 140 directly communicates with the feed pipe 131, which can ensure that the high-pressure flushing water in the flushing pipe set 140 maintains a large pressure to enter the feed pipe 131, and is beneficial to further improve the cleaning efficiency of the feed pipe 131 and ensure the cleaning strength of the feed pipe 131.

[0047] Further, when the feed pipe 131 is cleaned, the feed pump 120 needs to be stopped to stop the processing work, and after the cleaning is completed, in order to ensure that the feed pump 120 can normally operate, the feed pipe 131 communicated with the outlet 122 of the feed pump 120 needs to be filled with water before the feed pump 120 is started. In the prior art, water can only be injected from the inlet 121 of the feed pump 120 until the feed pipe 131 is filled with water. The flushing pipe group 140 of the embodiment of the present application can directly inject water into the feed pipe 131, and at the same time, water is injected at the inlet 121 of the feed pump 120. The two pipelines are injected at the same time, which can quickly fill the feed pipe 131 with water, thereby reducing the starting time of the feed pump 120. Therefore, the pipeline cleaning system 100 of the mineral processing equipment of the embodiment of the present application is also beneficial to save the downtime caused by cleaning the feed pipe 131 and improve the production efficiency.

[0048] In this way, the pipeline cleaning system 100 of the mineral processing equipment of the embodiment of the present application can improve the cleaning efficiency of the feed pipe 131, save the cleaning time, and on the other hand, shorten the restarting time of the feed pump 120 after cleaning, thereby effectively shortening the time of stopping the mineral processing equipment due to cleaning the feed pipe 131, and improving the production efficiency of the mineral processing equipment and reducing the operating cost.

[0049] In some implementable manners, as shown in Figure 1 and Figure 2 The flushing pipe group 140 of the embodiment of the present application comprises: a first flushing pipe 141 arranged at the outlet 122 side of the feed pump 120 and connected with the feed pipe 131 to supply flushing water into the feed pipe 131.

[0050] In some embodiments, the first flushing pipe 141 is arranged at the outlet 122 side of the feed pump 120, and a control valve 150 or other devices can be arranged at the connection between the first flushing pipe 141 and the feed pipe 131 to control the communication or closure between the first flushing pipe 141 and the feed pipe 131. When the mineral processing equipment normally operates, the control valve 150 remains closed, and when the feed pipe 131 needs to be cleaned, the control valve 150 is opened to inject flushing water into the feed pipe 131 through the first flushing pipe 141. The flushing water can be high-pressure water to improve the efficiency and intensity of flushing, which is not limited in the embodiment of the present application. In addition, the first flushing pipe 141 can be arranged at a position close to the feed pump 120 of the feed pipe 131, and the waste pipe 132 can be arranged at a position close to the feed inlet 111 of the feed pipe 131 to ensure that the flushing water can flush the entire feed pipe 131.

[0051] In some implementable manners, as shown in Figure 1 and Figure 2As shown, the flushing pipe group 140 of the embodiment of the present application further comprises a second flushing pipe 142, which is arranged at the inlet 121 side of the feed pump 120 and connected with the inlet 121 of the feed pump 120 to supply flushing water into the feed pump 120.

[0052] It can be understood that when flushing the feed pipe 131, the first flushing pipe 141 and the second flushing pipe 142 can start to inject flushing water at the same time. In the process that the flushing water in the first flushing pipe 141 is injected into the feed pipe 131 for flushing, the second flushing pipe 142 can inject flushing water into the feed pump 120 for cleaning the feed pump 120. When the flushing water in the feed pump 120 reaches the height of the outlet 122, it enters the feed pipe 131, and then the feed pipe 131 is flushed for the second time and discharged through the waste pipe 132. In this way, the first flushing pipe 141 and the second flushing pipe 142 can clean at the same time, which can further improve the cleaning efficiency and clean the feed pump 120 at the same time of cleaning the feed pipe 131, so that the cleaning is more comprehensive.

[0053] Meanwhile, when the mineral processing equipment is working normally, the second flushing pipe 142 can also be used as a feed pipe to deliver the raw material to be processed to the feed pump, which is beneficial to save the pipeline arrangement in the mineral processing equipment.

[0054] In some implementable manners, as shown in Figure 1 and Figure 2 the flushing pipe group 140 of the embodiment of the present application is configured to, when flushing the feed pipe 131, first flush the feed pipe 131 through the first flushing pipe 141 for a first preset time length, and then flush the feed pump 120 through the second flushing pipe 142.

[0055] It can be understood that when flushing the feed pipe 131, the feed pipe 131 can be first flushed clean through the first flushing pipe 141, and then the feed pump 120 is flushed through the second flushing pipe 142, which avoids the problem that when flushing at the same time, the ore pulp in the feed pump 120 and the feed pipe 131 is accumulated in the feed pipe 131 at the same time, causing the waste pipe 132 to be blocked.

[0056] In some implementable manners, as shown in Figure 1 and Figure 2 the flushing pipe group 140 of the embodiment of the present application further comprises a water inlet pump 143 connected with the first flushing pipe 141 to drive the flushing water to enter the feed pipe 131 through the first flushing pipe 141.

[0057] In a specific implementation, the water inlet pump 143 connected with the first flushing pipe 141 is arranged to drive the flushing water to enter the feeding pipe 131 through the first flushing pipe 141, so that the flushing water has a certain pressure, thereby improving the flushing strength on the feeding pipe 131, ensuring that the stubborn ore pulp attached to the inner wall of the feeding pipe 131 can be flushed down, guaranteeing the cleaning strength of the feeding pipe 131, being conducive to reducing the abrasion of other devices in the mineral processing equipment, and improving the reliability of the whole mineral processing equipment.

[0058] In some implementable manners, as shown in Figure 1 and Figure 2 , the embodiment of the present application further includes a control valve 150 arranged on the first flushing pipe 141 to control the opening and closing of the first flushing pipe 141.

[0059] It can be understood that, when the mineral processing equipment is in normal operation, the control valve 150 needs to be kept in a closed state to avoid the outflow of the raw material to be processed from the first flushing pipe 141 when the raw material is injected into the autoclave 110, and when the feeding pipe 131 needs to be cleaned, the control valve 150 is opened to quickly inject flushing water into the feeding pipe 131 for cleaning.

[0060] In some implementable manners, as shown in Figure 1 and Figure 2 , the autoclave 110 of the embodiment of the present application has a feeding valve 112 for controlling the opening and closing of the feeding port 111, and the feeding valve 112 is configured to be closed when the flushing pipe group 140 injects flushing water into the feeding pipe 131.

[0061] It should be noted that, when the feeding pipe 131 is flushed, although the flushing water can be discharged through the waste pipe 132, when the water flow speed in the waste pipe 132 is slow, there is still a possibility that sewage will enter the autoclave 110 through the feeding pipe 131, causing pollution of the autoclave 110, so the feeding valve 112 needs to be arranged at the feeding port 111, and the feeding valve 112 is kept in a closed state when the feeding pipe 131 is flushed, so as to guarantee the cleanliness of the autoclave 110.

[0062] In some implementable manners, as shown in Figure 1 and Figure 2 , the feeding port 111 of the embodiment of the present application is multiple, and the feeding pump 120, the working pipe group 130 and the flushing pipe group 140 are also multiple and correspond to each other.

[0063] In a specific implementation, in order to improve production efficiency and shorten the feeding time of the autoclave 110, the feeding port 111 is provided in a plurality of forms, and the number of the feeding pump 120, the working pipe group 130 and the flushing pipe group 140 corresponds to the number of the feeding port 111, so that when the mineral processing equipment is in normal operation, the plurality of feeding pipes 131 supply materials to the autoclave 110 through the plurality of feeding ports 111 at the same time, thereby effectively improving the material supply efficiency, and when cleaning is performed, the plurality of flushing pipe groups 140 start to inject flushing water at the same time, thereby cleaning the plurality of feeding pipes 131 at the same time.

[0064] In some possible implementation manners, referring to FIGS. 1, 2 and 3, Figure 1 and Figure 2 the embodiment of the present application further includes a waste discharge pump 160 arranged on the waste discharge pipe 132, and the waste discharge pump 160 is configured to be opened after the first flushing pipe 141 injects flushing water into the feeding pipe 131 for a second preset time length.

[0065] It can be understood that if the sewage discharge speed is too slow, part of the sewage may be deposited in the feeding pipe 131, and therefore, the waste discharge pump 160 arranged on the waste discharge pipe 132 can accelerate the discharge of the sewage, and the waste discharge pump 160 can be configured to be opened after the feeding pipe 131 injects flushing water for a second preset time length, and the specific value of the second preset time length is not limited in the embodiment of the present application and can be adjusted according to the state of the flushing water in the feeding pipe 131, for example, the second preset time length can be set as the time when the feeding pipe 131 is filled with flushing water, which is beneficial to ensure that all parts of the feeding pipe 131 are flushed and guarantee the comprehensiveness of the cleaning.

[0066] Referring to FIGS. 1, 2 and 3, Figure 1 and Figure 2 the embodiment of the present application further provides a mineral processing equipment including the pipeline cleaning system 100 of any of the mineral processing equipment.

[0067] The structure and working principle of the pipeline cleaning system 100 of the mineral processing equipment are described in detail in the above embodiment, and will not be described here.

[0068] In the embodiment of the present application, the pipeline cleaning system 100 of the mineral processing equipment can effectively improve the pipeline cleaning efficiency, save the maintenance time and operation cost of the mineral processing equipment, and is beneficial to improve the production efficiency of the mineral processing equipment. Compared with the prior art, the pipeline cleaning system 100 of the mineral processing equipment in the embodiment of the present application can flush the feeding pipe 131 more cleanly, which is helpful to reduce the wear of the feeding pump 120 and other devices in the mineral processing equipment and improve the service life of the mineral processing equipment. At the same time, the pipeline cleaning system 100 of the mineral processing equipment has a relatively simple structure and makes relatively small changes to the overall structure of the mineral processing equipment, and does not excessively increase the cost of the mineral processing equipment.

[0069] In summary, the pipeline cleaning system 100 of the mineral processing equipment and the mineral processing equipment provided by the embodiments of the present application, the pipeline cleaning system 100 of the mineral processing equipment comprises an autoclave 110, a feed pump 120, a working pipe group 130 and a flushing pipe group 140, the working pipe group 130 comprises a feed pipe 131 and a waste pipe 132, the flushing pipe group 140 comprises a first flushing pipe 141 and a second flushing pipe 142, two ends of the feed pipe 131 are in communication with an outlet 122 of the feed pump 120 and a feed port 111 of the autoclave 110 respectively, one end of the waste pipe 132 is in communication with the feed pipe 131, and the other end is used to be in communication with a sewage collection device, the first flushing pipe 141 is in communication with the feed pipe 131, and the second flushing pipe 142 is in communication with an inlet 121 of the feed pump 120. When the mineral processing equipment is in normal operation, the first flushing pipe 141 and the waste pipe 132 are both closed, the raw material to be processed enters the autoclave 110 through the second flushing pipe 142, the feed pump 120 and the feed pipe 131 in turn to react, when the feed pipe 131 needs to be cleaned, the feed pump 120 is closed to stop running, the first flushing pipe 141 and the waste pipe 132 are opened, the feed port 111 is closed, and the first flushing pipe 141 injects flushing water into the feed pipe 131 to clean the feed pipe 131, after a certain cleaning time, the second flushing pipe 142 injects flushing water into the feed pump 120 to flush the feed pump 120, and at the same time, the feed pipe 131 can be flushed again, and the flushed sewage is discharged through the waste pipe 132. After cleaning is completed, the waste pipe 132 is closed, the first flushing pipe 141 is filled with raw water in the water supply pipe, and then the feed pump 120 can be started, and the mineral processing equipment resumes normal operation. Thus, the pipeline cleaning system 100 of the mineral processing equipment provided by the embodiments of the present application can flush through the first flushing pipe 141 and the second flushing pipe 142 at the same time, effectively improves the pipeline cleaning efficiency, saves the downtime required for cleaning the pipeline, and thus is conducive to improving the overall production efficiency and operating cost of the mineral processing equipment.
