Description

Technical Field

[0001] The utility model belongs to the technical field of phosphate preparation, and specifically relates to an impurity removal device for phosphate preparation. Background Art

[0002] The mother liquor filter is one of the key equipment in the preparation of phosphate mother liquor. Since the phosphate mother liquor always contains a certain amount of impurities, if it is not filtered, the impurities will enter the phosphate and affect its purity and quality, seriously affecting the phosphate production. Therefore, in the phosphate mother liquor process, the mother liquor must be filtered to remove particles larger than a certain size before injection.

[0003] When the existing impurity removal device filters the phosphate mother liquor, the filter screen needs to be removed when cleaning the impurities on the filter screen, which makes the cleaning process of the device troublesome and reduces the filtering efficiency of the mother liquor.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art. Utility Model Content

[0005] The utility model aims to provide an impurity removal device for phosphate preparation, which can solve the problem of troublesome filter screen cleaning when the impurity removal device filters phosphate mother liquor.

[0006] In order to achieve the above purpose, the technical solution provided by a specific embodiment of the utility model is as follows:

[0007] A device for removing impurities for preparing phosphate, comprising:

[0008] The impurity removal device comprises an impurity removal device body, wherein the phosphate mother liquor is in the impurity removal device body, and the phosphate mother liquor can be filtered through the filter element. The impurity removal device body is installed with an upper cover plate, and the impurity removal device body is easy to open through the upper cover plate, so as to facilitate the maintenance and replacement of the components in the impurity removal device body. The upper cover plate is installed with a feed inlet, and the phosphate mother liquor is added into the impurity removal device body through the feed inlet for filtering.

[0009] The filter assembly includes a filter screen, which is rotatably mounted in the impurity removal device body. The filter screen is a component for filtering phosphate mother liquor, thereby filtering the mother liquor added to the impurity removal device body. A pair of bearings are symmetrically mounted on the side wall of the impurity removal device body with the central axis of the impurity removal device body as the symmetry axis, and a pair of rotating shafts are installed in the pair of bearings in a penetrating manner, so that the rotating shafts can rotate under the action of the bearings. A pair of hexagonal socket rods are fixedly connected to one end of the pair of rotating shafts placed in the impurity removal device body, and a pair of hexagonal socket grooves are symmetrically opened on the side wall of the filter screen with the center of the filter screen as the symmetry axis. A pair of hexagonal socket rods are respectively socketed in a pair of hexagonal socket grooves. Through the cooperation of the hexagonal socket rods and the hexagonal socket grooves, the filter screen can be driven to rotate when the rotating shaft rotates, thereby realizing the rotation of the filter screen installed in the filter screen. When the filter is filtering the phosphate mother liquor and a large number of impurities are intercepted on the filter and need to be cleaned, the filter is driven to rotate by rotating the rotating shaft so that the upper and lower surfaces of the filter are interchanged, and the impurities on the filter can be cleaned by flushing. This makes it possible to clean the impurities on the filter without removing the filter, and the cleaning process is convenient and can be cleaned, making it easy to clean the filter.

[0010] In one or more embodiments of the utility model, a diversion shell is installed at the bottom of the upper cover plate, and the diversion shell is arranged directly below the feed inlet. The diversion shell can divert the phosphate mother liquor added into the impurity removal device body through the feed inlet, thereby improving the effect of filtering the mother liquor. A connecting rod is fixedly connected to the outer side wall of the diversion shell, and one end of the connecting rod away from the diversion shell is fixedly connected to the bottom side wall of the upper cover plate.

[0011] In one or more embodiments of the utility model, the interior of the diverter shell is set as a hollow structure and the upper end is set as an opening, so that the mother liquid can flow through the inside of the diverter shell when added, and can also flow on the outer side wall of the diverter shell. The shape of the diverter shell is an inverted cone, so that the mother liquid flowing through the outer side wall of the diverter shell will be diverted to the surrounding of the diverter shell.

[0012] In one or more embodiments of the utility model, a connecting ear is integrally formed at the upper end of the impurity removal device body, the upper cover is installed on the connecting ear, and fixing bolts are installed on the upper cover and the connecting ear, so that the upper cover is easy to disassemble and assemble.

[0013] In one or more embodiments of the utility model, a discharge port is installed at the bottom of the impurity removal device body, and the filtered mother liquid is discharged through the discharge port. A discharge valve is installed on the discharge port, and the discharge valve is used to control the opening and closing of the discharge port.

[0014] In one or more embodiments of the utility model, a sealing layer is installed between the outer side wall of the bearing and the side wall of the impurity removal device body, so that the bearing has good sealing performance after installation. The sealing layer is made of corrosion-resistant material. Since the mother liquid is corrosive, the sealing layer needs to be corrosion-resistant.

[0015] In one or more embodiments of the utility model, a pair of limit frames are fixedly connected to the outer wall of the impurity removal device body, and one end of a pair of rotating shafts located on the outside of the impurity removal device body respectively passes through the inside of the limit frame and is placed on the outside of the limit frame. The filter net needs to be stable when in use, so the rotation of the filter net is restricted by setting a limit frame.

[0016] In one or more embodiments of the present invention, a first sleeve hole is provided on the side wall of the rotating shaft and the limiting frame, and a second sleeve hole is provided on the end of the rotating shaft disposed outside the limiting frame.

[0017] In one or more embodiments of the utility model, a sleeve rod is sleeved on the limit frame and the rotating shaft through the first sleeve hole, and one end of the rotating shaft placed outside the limit frame through the second sleeve hole. By installing the sleeve rod in the first sleeve hole opened on the rotating shaft and the limit frame, the rotation of the filter screen can be restricted by the sleeve rod. By sleeved the sleeve rod in the second sleeve hole, the rotating shaft can be driven to rotate by the sleeve rod, thereby driving the rotation of the filter screen. Since the first sleeve hole is opened in a through manner on the rotating shaft and the limit frame, when the filter screen rotates 180 degrees, the sleeve rod can be inserted into the first sleeve hole, thereby restricting the rotation of the filter screen, so that the filter screen can be used directly after being cleaned.

[0018] In one or more embodiments of the utility model, a pair of lifting ears are fixedly connected to both sides of the upper end wall plate of the filter screen, and the filter screen can be removed from the impurity removal device body through the lifting ears. A sealing ring is installed on the outer side wall of the filter screen, and the sealing ring is arranged between the inner side wall of the impurity removal device body and the outer side wall of the filter screen. Under the action of the sealing ring, the sealing performance between the filter screen and the impurity removal device body is better, so that the mother liquid entering the impurity removal device body needs to be filtered through the filter screen.

[0019] Compared with the prior art, the utility model installs the filter screen in a rotatable manner. When the filter screen needs to be cleaned, the filter screen is rotated so that the upper and lower surfaces of the filter screen are interchanged, and impurities on the filter screen can be cleaned by flushing or the like, making it convenient to clean impurities on the filter screen. After cleaning, the filter screen can be used directly, thereby improving the efficiency of mother liquor filtration. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0030] like Figure 1 to Figure 4 As shown, a phosphate preparation impurity removal device in one embodiment of the utility model includes an impurity removal device 1 and a filter component 2.

[0031] like Figure 1 to Figure 4 As shown, the impurity removal device 1 includes an impurity removal device body 11. The phosphate mother liquor is in the impurity removal device body 11. The phosphate mother liquor can be filtered through the filter element. An upper cover plate 12 is installed on the impurity removal device body 11. The upper cover plate 12 makes it easy to open the impurity removal device body 11, so as to facilitate the maintenance and replacement of the internal components of the impurity removal device body 11. A feed port 13 is installed on the upper cover plate 12, and the phosphate mother liquor is added into the impurity removal device body 11 through the feed port 13 for filtering.

[0032] like Figure 4 As shown, a diverter shell 14 is installed at the bottom of the upper cover plate 12. The diverter shell 14 is arranged directly below the feed port 13. The diverter shell 14 can divert the phosphate mother liquor added into the impurity removal device body 11 through the feed port 13, thereby improving the effect of filtering the mother liquor. A connecting rod 15 is fixedly connected to the outer side wall of the diverter shell 14, and one end of the connecting rod 15 away from the diverter shell 14 is fixedly connected to the bottom side wall of the upper cover plate 12.

[0033] like Figure 4 As shown, the interior of the diverter shell 14 is set as a hollow structure and the upper end is set as an opening, so that the mother liquid can flow through the inside of the diverter shell 14 when added, and can also flow on the outer wall of the diverter shell 14. The shape of the diverter shell 14 is an inverted cone, so that the mother liquid flowing through the outer wall of the diverter shell 14 will be diverted to the surrounding of the diverter shell 14.

[0034] like Figure 1 and Figure 4 As shown, a connecting ear 16 is integrally formed at the upper end of the impurity removal device body 11, and the upper cover plate 12 is installed on the connecting ear 16. Fixing bolts 17 are installed on the upper cover plate 12 and the connecting ear 16, and the fixing bolts 17 make it easy to disassemble and assemble the upper cover plate 12.

[0035] like Figure 1 and Figure 4 As shown, a discharge port 18 is installed at the bottom of the impurity removal device body 11, and the filtered mother liquid is discharged through the discharge port 18. A discharge valve 19 is installed on the discharge port 18, and the discharge valve 19 is used to control the switch of the discharge port 18.

[0036] like Figure 3 , Figure 4 and Figure 6As shown, the filter assembly 2 includes a filter screen 21, which is rotatably mounted in the impurity removal device body 11. The filter screen 21 is a component for filtering the phosphate mother liquor, thereby filtering the mother liquor added to the impurity removal device body 11. A pair of bearings 22 are symmetrically mounted on the side wall of the impurity removal device body 11 with the central axis of the impurity removal device body 11 as the symmetry axis, and a pair of rotating shafts 23 are installed in the pair of bearings 22 in a penetrating manner, and the rotating shafts 23 can be rotated under the action of the bearings 22. A pair of rotating shafts 23 are placed in the impurity removal device body 11, and one end thereof is fixedly connected to a pair of hexagonal socket rods 24. A pair of hexagonal socket grooves 25 are symmetrically provided on the side wall of the filter screen 21 with the center of the filter screen 21 as the symmetry axis. The pair of hexagonal socket rods 24 are respectively socketed in the pair of hexagonal socket grooves 25. Through the cooperation of the hexagonal socket rods 24 and the hexagonal socket grooves 25, the filter screen 21 can be driven to rotate when the rotating shaft 23 rotates, thereby realizing the rotation of the filter screen 21 installed in the filter screen 21.

[0037] Preferably, when the filter screen 21 is filtering the phosphate mother liquor and a large number of impurities are intercepted on the filter screen 21 and need to be cleaned, the filter screen 21 is driven to rotate by the rotation of the rotating shaft 23 so that the upper and lower surfaces of the filter screen 21 are interchanged, and the impurities on the filter screen 21 can be cleaned by flushing or the like, so that when cleaning the impurities on the filter screen 21, there is no need to remove the filter screen 21, and the cleaning process is convenient and can be cleaned, so that the filter screen 21 is easy to clean.

[0038] like Figure 5 As shown, a sealing layer 26 is installed between the outer wall of the bearing 22 and the side wall of the impurity removal device body 11, so that the bearing 22 has good sealing performance after installation. The sealing layer 26 is made of corrosion-resistant material. Since the mother liquid is corrosive, the sealing layer 26 needs to have corrosion resistance.

[0039] like Figure 1 and Figure 5 As shown, a pair of limit frames 27 are fixedly connected to the outer wall of the impurity removal device body 11, and one end of a pair of rotating shafts 23 is placed on the outside of the impurity removal device body 11, respectively passing through the inside of the limit frame 27 and being placed on the outside of the limit frame 27. The filter screen 21 needs to be stable when in use, so the rotation of the filter screen 21 is restricted by setting the limit frame 27.

[0040] like Figure 2 and Figure 6 As shown, a first sleeve hole 28 is formed on the side walls of the rotating shaft 23 and the limiting frame 27 , and a second sleeve hole 29 is formed on one end of the rotating shaft 23 disposed outside the limiting frame 27 .

[0041] like Figure 2 and Figure 6As shown, a sleeve rod 210 is sleeved on the limit frame 27 and the rotating shaft 23 through the first sleeve hole 28, and one end of the rotating shaft 23 placed outside the limit frame 27 through the second sleeve hole 29. By installing the sleeve rod 210 in the first sleeve hole 28 opened on the rotating shaft 23 and the limit frame 27, the rotation of the filter screen 21 can be restricted by the sleeve rod 210. By sleeved the sleeve rod 210 in the second sleeve hole 29, the sleeve rod 210 is convenient to drive the rotating shaft 23 to rotate, thereby driving the rotation of the filter screen 21. Since the first sleeve hole 28 is opened on the rotating shaft 23 and the limit frame 27 in a penetrating manner, when the filter screen 21 rotates 180 degrees, the sleeve rod 210 can be inserted into the first sleeve hole 28, thereby restricting the rotation of the filter screen 21, so that the filter screen 21 can be directly used after being cleaned.

[0042] like Figure 6 As shown, a pair of lifting ears 212 are fixedly connected to both sides of the upper end wall plate of the filter screen 21, and the filter screen 21 can be removed from the impurity removal device body 11 through the lifting ears 212. A sealing ring 211 is installed on the outer wall of the filter screen 21, and the sealing ring 211 is arranged between the inner wall of the impurity removal device body 11 and the outer wall of the filter screen 21. Under the action of the sealing ring 211, the sealing performance between the filter screen 21 and the impurity removal device body 11 is better, so that the mother liquid entering the impurity removal device body 11 needs to be filtered through the filter screen 21.

[0043] Preferably, since the phosphate mother solution is corrosive, the parts in contact with the phosphate should be made of corrosion-resistant materials.

[0044] When in use, the phosphate mother liquor is added into the impurity removal device body 11 through the feed port 13. When added, the phosphate will fall on the diversion shell 14. The mother liquor falls on the filter screen 21 after being diverted by the diversion shell 14. After being filtered by the filter screen 21, the mother liquor can be discharged from the impurity removal device body 11 through the discharge port 18.

[0045] When there are many impurities intercepted on the filter screen 21 and they need to be filtered, the sleeve rod 210 sleeved between the limit frames 27 and the rotating shaft 23 on both sides of the impurity removal device body 11 is removed, and then the sleeve rod 210 on the second sleeve hole 29 is rotated, so that the rotating shaft 23 can drive the filter screen 21 to rotate, so that the positions of the upper and lower surfaces of the filter screen 21 are interchanged, and then the sleeve rod 210 is inserted into the first sleeve hole 28 on the limit frame 27 and the rotating shaft 23, so that the position of the filter screen 21 is fixed, and the filter screen 21 can be cleaned by flushing or the like. After the filter screen 21 is cleaned, the mother liquor can be filtered.

[0046] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
