Description

Technical Field

[0001] This utility model relates to the technical field of calcium phosphate production equipment, and in particular to an ore feeding device for calcium phosphate production. Background Technology

[0002] When producing superphosphate using the mineral powder method, the phosphate ore, after primary crushing by a jaw crusher, needs to be conveyed to a double roll crusher for further crushing. During this transfer, the phosphate ore is transferred via a belt conveyor system, and the primary crushed phosphate ore is temporarily stored in a storage tank. The jaw crusher can continue operating even when the double roll crusher is shut down.

[0003] The storage tank used for temporarily storing phosphate rock has a circular upper section and a tapered lower section that is wider at the top and narrower at the bottom. The tank has a feed inlet at the top and a discharge outlet at the bottom. A valve plate is installed at the discharge outlet to open or close it. During operation of the double-roll crusher, the valve plate is opened, and the phosphate rock in the storage tank falls onto the conveyor belt below.

[0004] However, during normal use, phosphate rock in the storage tank easily clogs the area above the discharge port. To solve this problem, workers typically use a hammer to tap the discharge port of the storage tank, using vibration to clear the blockage. However, prolonged tapping can deform the tank wall, creating numerous protrusions on the inner wall above the discharge port. These protrusions make the inner wall rough, increasing the resistance to the falling phosphate rock and exacerbating the blockage. To address these issues, technicians have improved the existing storage tank. Utility Model Content

[0005] The purpose of this invention is to provide an ore feeding device for calcium phosphate production to solve the problem of easy clogging of the phosphate ore outlet.

[0006] To achieve the above objectives, this utility model provides an ore feeding device for calcium phosphate production, including a storage tank with a discharge port at the bottom. A receiving hopper is located below the discharge port of the storage tank. The receiving hopper is connected and fixed to the storage tank by multiple connecting rods. A connecting frame is installed at the lower end of the receiving hopper, and a baffle structure is installed on the connecting frame to control the material falling into the receiving hopper.

[0007] The connecting frame is provided with multiple insertion holes on one side or on both opposite sides, and the material blocking structure consists of multiple insert rods, which are movably inserted into the insertion holes respectively.

[0008] The connecting frame includes a first profile, a second profile, and a third profile. The second profile and the third profile are fixedly connected to both ends of the two first profiles. The insertion hole passes through the second profile and the third profile. The frame enclosed by the two first profiles and the two second profiles is fixedly installed at the lower end of the receiving hopper.

[0009] The two ends of the connecting rod are fixed to the outer wall of the storage tank and the inner wall of the receiving hopper, respectively. The connecting rod is a tubular structure. The storage tank and the receiving hopper are provided with through holes at the positions corresponding to the central holes of the connecting rod. The top rod slides through the through holes.

[0010] The connecting rod has a longitudinal elongated hole, and the limiting pin is inserted into the elongated hole and connected to the top rod.

[0011] The outer wall of the receiving hopper is equipped with a push rod device at the position corresponding to the through hole. The telescopic end of the push rod device extends into the through hole, and the top rod is slidably installed in the through hole. The telescopic end of the push rod device is fixedly connected to the top rod.

[0012] The connecting rod has a longitudinal elongated hole, and the end of the top rod connected to the telescopic end has a blind hole. The telescopic end of the push rod device is inserted into the blind hole, and the limiting pin is inserted into the elongated hole and then connected to the top rod and the telescopic end located in the blind hole.

[0038] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0039] Example 1:

[0040] Please see Figure 1-7 A feeding device for calcium phosphate production includes a storage tank 10, a discharge port 11 at the bottom of the storage tank 10, a receiving hopper 20 located below the discharge port 11, the receiving hopper 20 being welded and fixed to the storage tank 10 by multiple connecting rods 30, a connecting frame 40 being installed at the lower end of the receiving hopper 20, and a baffle structure 50 being installed on the connecting frame 40, the baffle structure 50 being used to control the falling of material in the receiving hopper 20.

[0041] By installing a receiving hopper 20 below the storage tank 10, the diameter of the discharge port 11 can be increased, facilitating the discharge of phosphate rock from the storage tank 10 and preventing blockage. A connecting frame 40 is installed at the lower end of the receiving hopper 20, and a baffle structure 50 is installed on the connecting frame 40 to control the material falling from the receiving hopper 20.

[0042] In this embodiment, the baffle structure 50 can be a valve plate that is laterally slidably mounted on the connecting frame 40. By pushing and pulling the valve plate, the falling material in the receiving hopper 20 is controlled.

[0043] During production, the phosphate rock in the storage tank 10 falls onto the receiving hopper 20 and then onto the conveyor belt below via the connecting frame 40. If the outlet 11 of the storage tank 10 becomes blocked, a hook-shaped tool can be inserted into the outlet 11 through the space between the storage tank 10 and the receiving hopper 20 to clear the blockage.

[0044] When the double roll crusher needs to be stopped, first close the material blocking structure 50. At this time, the phosphate rock accumulates in the receiving hopper 20. As the phosphate rock accumulates, it blocks the discharge port 11 above. At this time, the phosphate rock in the storage tank 10 will no longer fall.

[0045] Further, see Figure 1 A guide pipe 60 is installed at the bottom of the connecting frame 40 to facilitate the concentrated falling of phosphate rock onto the conveyor belt below. The guide pipe 60 can be welded to the lower side of the connecting frame 40 or bolted to the connecting frame 40 via a flange structure.

[0046] Example 2:

[0047] The difference between this embodiment and Embodiment 1 is that, see [link to Embodiment 1] Figure 1 , 5 6. Multiple insertion holes 44 are provided on one side or opposite sides of the connecting frame 40. The material blocking structure 50 consists of multiple insert rods, which are movably inserted into the insertion holes 44. Since each insert rod is independent, the force-bearing area of ​​a single rod is small, making it easy to push and pull for adjustment during production. After all the insert rods are adjusted, a support surface is formed, thereby controlling the fall of phosphate rock in the receiving hopper 20.

[0048] When the insert rod is pulled out, it facilitates material discharge; when the insert rod is pulled in, it can close the connecting frame 40.

[0049] In this embodiment, see Figure 5 , 6 The connecting frame 40 includes a first profile 41, a second profile 42 and a third profile 43. The two ends of the two first profiles 41 are fixedly connected to the second profile 42 and the third profile 43. The insertion hole 44 passes through the second profile 42 and the third profile 43. The frame enclosed by the two first profiles 41 and the two second profiles 42 is fixedly installed at the lower end of the receiving hopper 20.

[0050] Specifically, the first profile 41, the second profile 42, and the third profile 43 are all channel steel, and the connecting frame 40 is made of welded channel steel.

[0051] Example 3:

[0052] Based on Example 1 or Example 2, see Figure 1 , 3 The two ends of the connecting rod 30 are fixed to the outer wall of the storage tank 10 and the inner wall of the receiving hopper 20, respectively. The connecting rod 30 is a tubular structure. The storage tank 10 and the receiving hopper 20 are provided with through holes 12 at the positions corresponding to the central holes of the connecting rod 30. The top rod 80 slides through the through holes 12.

[0053] The connecting rod 30 has a tubular structure. The storage tank 10 and the receiving hopper 20 have through holes 12 at the positions corresponding to the central holes of the connecting rod 30. The push rod 80 slides into the through hole 12. When the outlet 11 of the storage tank 10 is blocked, the push rod 80 can be held at one end located on the outer wall of the receiving hopper 20 and moved back and forth along the through hole 12, allowing the push rod 80 to extend into the storage tank 10 and clear the blockage. When the outlet 11 is not blocked, the front end of the push rod 80 is located inside the through hole 12, but does not extend beyond the inner wall of the storage tank 10.

[0054] To limit the movement of the push rod 80, a longitudinal elongated hole 31 is provided on the connecting rod 30. The limiting pin 90 passes through the elongated hole 31 and connects with the push rod 80. In this way, the push rod 80 can only move within the range of the elongated hole 31.

[0055] In the preferred embodiment, when the limiting pin 90 abuts against the end of the elongated hole 31 near the storage tank 10, the front end of the push rod 80 extends into the storage tank 10; when the limiting pin 90 abuts against the end of the elongated hole 31 away from the storage tank 10, the front end of the push rod 80 is approximately flush with the inner wall of the storage tank 10.

[0056] Example 4:

[0057] In Example 3, a worker needs to operate the push rod 80 to clear the discharge port 11. In this example, see... Figures 1-4 A push rod device 70 is installed on the outer wall of the receiving hopper 20 at the position corresponding to the through hole 12. The telescopic end 71 of the push rod device 70 extends into the through hole 12, and the top rod 80 is slidably installed in the through hole 12. The telescopic end 71 of the push rod device 70 is fixedly connected to the top rod 80. By installing the push rod device 70 on the outer wall of the receiving hopper 20, the extension and retraction of the telescopic end 71 of the push rod device 70 drives the extension and retraction of the top rod 80, thereby realizing automatic operation.

[0058] In this embodiment, the push rod device 70 can be any one of a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, or an electric push rod.

[0059] Specifically, see Figure 3 , 4 The connecting rod 30 has a longitudinal elongated hole 31, and the end of the push rod 80 connected to the telescopic end 71 has a blind hole 81. The telescopic end 71 of the push rod device 70 is inserted into the blind hole 81. After the limiting pin 90 passes through the elongated hole 31, it is connected to the push rod 80 and the telescopic end 71 located in the blind hole 81. Through the above structure, the telescopic end 71 of the push rod device 70 is connected to the push rod 80, and the push rod 80 is prevented from rotating arbitrarily.

[0060] In this embodiment, the limiting pin 90 is a bolt.

[0061] Furthermore, to facilitate the installation of the push rod device 70 on the outer wall of the receiving hopper 20, see [reference needed]. Figure 3 A connecting plate 21 is welded and installed on the outer wall of the receiving hopper 20 at the position corresponding to the through hole 12. The push rod device 70 is installed on the connecting plate 21 by bolts. The connecting plate 21 is provided with a through hole corresponding to the through hole 12. The telescopic end 71 of the push rod device 70 passes through the through hole on the connecting plate 21.

[0062] Furthermore, a sealing ring groove is provided in the through hole on the connecting plate 21, and a sealing ring 22 is installed in the sealing ring groove. The sealing ring 22 is installed to scrape off any dust that may adhere to the telescopic end 71 of the push rod device 70.

[0063] In this embodiment, the sealing ring 22 is a skeleton sealing ring or a U-shaped sealing ring.

[0064] The working principle or operation process of this utility model is as follows:

[0065] See Figure 1 By installing a receiving hopper 20 below the storage tank 10, the diameter of the discharge port 11 can be increased, facilitating the discharge of phosphate rock from the storage tank 10 and preventing blockage. A connecting frame 40 is installed at the lower end of the receiving hopper 20, and a baffle structure 50 is installed on the connecting frame 40. The baffle structure 50 controls the material falling from the receiving hopper 20. When the roller crusher needs to be stopped, the baffle structure 50 is closed first. At this time, the phosphate rock accumulates in the receiving hopper 20. As the phosphate rock accumulates, it blocks the discharge port 11 above, preventing the phosphate rock from falling from the storage tank 10.

[0066] When the outlet 11 of the storage tank 10 is blocked, the extension and retraction of the telescopic end 71 of the push rod device 70 is controlled to drive the push rod 80 to extend and retract. See [link to relevant documentation]. Figure 7 This allows the top rod 80 to extend and retract automatically, thereby clearing the discharge port 11.
