Description

Technical Field

[0001] This utility model relates to the field of polyaluminum ferric chloride production technology, specifically a pulverizing device for polyaluminum ferric chloride production. Background Technology

[0002] Polyaluminum ferric chloride (PAFC), as a novel and highly efficient inorganic polymeric composite flocculant, combines the charge neutralization capacity of polyaluminum chloride (PAC) with the adsorption bridging properties of polyferric chloride (PFC). It is widely used in industrial wastewater treatment, drinking water purification, and sludge dewatering. Its raw materials usually include aluminum-iron minerals such as bauxite, coal gangue, and fly ash, or are obtained through the chemical synthesis of aluminum and iron salts. However, natural mineral raw materials are mostly in the form of lumps or granules with uneven particle size distribution. Direct participation in the reaction can lead to problems such as low dissolution efficiency and incomplete reaction, which in turn affects the flocculation performance and stability of the product. Therefore, the pretreatment of raw materials has become a key step in the production of PAFC.

[0003] Traditional pulverizing devices have significant limitations when processing PAFC raw materials. For example, a single pulverizing device cannot achieve precise control of particle size, resulting in a wide particle size distribution after pulverization, with fine powder and coarse particles mixed together, which affects the uniformity of subsequent reactions. Furthermore, different mineral raw materials have different sizes, which can easily cause blockage of the pulverizing device during the pulverization process. Therefore, a pulverizing device for the production of polyaluminum ferric chloride is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a pulverizing device for the production of polyaluminum ferric chloride, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pulverizing device for the production of polyaluminum ferric chloride, comprising: a mounting box, wherein a first grinding seat and a second grinding seat are slidably connected inside the mounting box, and two hydraulic cylinders are fixedly connected to both sides of the mounting box. The hydraulic cylinders penetrate the outer wall of the mounting box and are fixedly connected to connecting plates. The two connecting plates are respectively connected to the outer walls of the first grinding seat and the second grinding seat by bolts. Both the first grinding seat and the second grinding seat have inlets on their outer sides, and outlets on the side of the first grinding seat and the second grinding seat away from the inlets. A grinding chamber is formed at the center of the first grinding seat and the second grinding seat, and the grinding chamber is connected to the inlet and the outlet. Grinding balls are rotatably connected inside the grinding chamber, and connecting rods are fixedly connected to the outer sides of the grinding balls. One end of the connecting rod penetrates the outer wall of the second grinding seat and one of the connecting plates and is fixedly connected to a drive motor. The drive motor is fixedly connected to the outside of the mounting box.

[0006] As a further preferred embodiment of this technical solution: the bottom of the mounting box is fixedly connected to an inclined seat, and the bottom of the inclined seat is fixedly connected to a support base. The inclined seat is used to provide inclined support for the mounting box, so that the entire mounting box is tilted.

[0007] As a further preferred embodiment of this technical solution: the first grinding seat and the second grinding seat are integrally formed with wear-resistant elastic connecting rubber on their adjacent sides.

[0008] As a further preferred embodiment of this technical solution: a sliding groove is provided inside the discharge port, and a baffle plate is slidably connected inside the sliding groove, the baffle plate being used to block the discharge port.

[0009] As a further preferred embodiment of this technical solution: a first electromagnet is fixedly connected to one side of the baffle plate, and a second electromagnet is fixedly connected inside the discharge port.

[0010] As a further preferred embodiment of this technical solution: the bottom of the baffle plate and the first electromagnet are fixedly connected to a universal ball, and a guide groove is provided on the inner bottom wall of the discharge port, and the universal ball is slidably connected to the inside of the guide groove.

[0011] As a further preferred embodiment of this technical solution: both the first grinding base and the second grinding base are fixedly connected to the outside of a feed pipe, and an elastic rubber connecting section is fixedly connected between the two feed pipes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by activating two sets of hydraulic cylinders, the first grinding seat and the second grinding seat can be moved inside the mounting box, causing them to approach or separate from each other. When the first grinding seat and the second grinding seat approach each other, the inner wall of the grinding chamber is closer to the outer wall of the grinding ball, forming a stronger squeezing and grinding effect on the material, thereby obtaining a finer grinding effect and solving the problem of wide particle size distribution of the material after crushing;

[0014] 2. In this invention, when the first and second grinding seats are separated by two sets of hydraulic cylinders, the grinding chamber forms two semi-circular grinding cavities, which effectively separate the clogged material from the grinding balls and the grinding chamber. When a blockage occurs, the operator can promptly separate the first and second grinding seats, clear the blockage, and then use the hydraulic cylinders to bring them closer together again to resume the grinding operation. Furthermore, the continuous close proximity process further compresses and grinds the raw material, enhancing the fineness of the pulverization. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example

[0024] Please see Figures 1-6This utility model provides a technical solution: a pulverizing device for the production of polyaluminum ferric chloride, comprising: a mounting box 3, with a first grinding seat 4 and a second grinding seat 5 slidably connected inside the mounting box 3; two hydraulic cylinders 7 are fixedly connected to both sides of the mounting box 3; the hydraulic cylinders 7 penetrate the outer wall of the mounting box 3 and are fixedly connected to connecting plates 6; the two connecting plates 6 are respectively connected to the outer walls of the first grinding seat 4 and the second grinding seat 5 by bolts; both the first grinding seat 4 and the second grinding seat 5 have inlet ports 12 on their outer sides; the first grinding seat 4 and the second grinding seat 5 have outlet ports 13 on their side away from the inlet ports 12; a grinding chamber 9 is formed at the center of the first grinding seat 4 and the second grinding seat 5; the grinding chamber 9 is connected to the inlet ports 12 and the outlet ports 13; a grinding ball 10 is rotatably connected inside the grinding chamber 9; a connecting rod 11 is fixedly connected to the outside of the grinding ball 10; one end of the connecting rod 11 penetrates the outer wall of the second grinding seat 5 and one of the connecting plates 6 and is fixedly connected to a drive motor 8; the drive motor 8 is fixedly connected to the outside of the mounting box 3.

[0025] In this embodiment, specifically: during use, the operator can feed the raw material to be crushed into the feed inlet 12. When the material enters the feed inlet 12, it will enter the grinding chamber 9 along the channel of the feed inlet 12. When the raw material enters the grinding chamber 9, the drive motor 8 will drive the connecting rod 11 to rotate. When the connecting rod 11 rotates, it will drive the grinding ball 10 to rotate. When the grinding ball 10 continues to rotate inside the grinding chamber 9, it can continuously grind the raw material inside the grinding chamber 9. The inner wall of the grinding chamber 9 and the outer wall of the grinding ball 10 are both set as rough grinding surfaces, which can achieve a finer grinding process during the crushing of materials.

[0026] In this embodiment, specifically: during use, two sets of hydraulic cylinders 7 can be activated. When the two sets of hydraulic cylinders 7 are activated, they can drive the first grinding seat 4 and the second grinding seat 5 to move inside the mounting box 3, so that the first grinding seat 4 and the second grinding seat 5 can approach and separate from each other. When the first grinding seat 4 and the second grinding seat 5 approach each other, the inner wall of the grinding chamber 9 can be closer to the outer wall of the grinding ball 10, thereby further squeezing and grinding the material, thus forming a finer grinding effect and reducing the problem of wide particle size distribution of the crushed material.

[0027] In this embodiment, specifically: when the two sets of hydraulic cylinders 7 drive the first grinding seat 4 and the second grinding seat 5 to separate from each other, more material can enter the grinding chamber 9. Furthermore, the first grinding seat 4 and the second grinding seat 5 can be separated even when blockage occurs inside the grinding chamber 9. By separating the first grinding seat 4 and the second grinding seat 5, the grinding chamber 9 forms two semi-circular grinding cavities, which separate the blocked material from the grinding ball 10 and the grinding chamber 9. After separation, the first grinding seat 4 and the second grinding seat 5 are driven to move closer to each other again by the hydraulic cylinder 7, thereby achieving the effect of multiple grinding and pulverizing of multiple materials.

[0028] like Figure 1 As shown, a tilting seat 2 is fixedly connected to the bottom of the mounting box 3, and a support base 1 is fixedly connected to the bottom of the tilting seat 2. The tilting seat 2 is used to tilt the mounting box 3, so that the mounting box 3 as a whole tilts.

[0029] In this embodiment, specifically: during use, the mounting box 3 is tilted and supported by the support base 1 and the tilting seat 2, so that after the material is crushed and ground, it is discharged from the interior of the grinding chamber 9 along the tilt angle of the mounting box 3 and the discharge port 13.

[0030] like Figure 2 As shown, the first grinding seat 4 and the second grinding seat 5 are integrally formed with wear-resistant elastic connecting rubber 14 on their adjacent sides.

[0031] In this embodiment, specifically: when the first grinding seat 4 and the second grinding seat 5 are separated by the hydraulic cylinder 7, in order to prevent some material from entering between the first grinding seat 4 and the second grinding seat 5 and affecting the secondary bonding of the first grinding seat 4 and the second grinding seat 5, a wear-resistant elastic connecting rubber 14 is provided between the first grinding seat 4 and the second grinding seat 5. With the setting of the wear-resistant elastic connecting rubber 14, when the first grinding seat 4 and the second grinding seat 5 are separated, the wear-resistant elastic connecting rubber 14 will deform and form a connecting layer between the first grinding seat 4 and the second grinding seat 5, preventing material from falling out of the interior of the grinding chamber 9.

[0032] In this embodiment, specifically: the first grinding seat 4 and the second grinding seat 5 can be set to be perpendicular to the ground, so that the material can fall towards the discharge port 13 by gravity instead of falling between the first grinding seat 4 and the second grinding seat 5.

[0033] like Figures 4-5 As shown, a sliding groove 15 is provided inside the discharge port 13, and a baffle plate 16 is slidably connected inside the sliding groove 15. The baffle plate 16 is used to block the discharge port 13.

[0034] In this embodiment, specifically: the sliding groove 15 is used to store the baffle plate 16, and during the grinding process, the baffle plate 16 blocks the discharge port 13, thereby preventing the material from being thrown out of the discharge port 13 by the centrifugal force generated by the grinding ball 10 after only one grinding.

[0035] like Figures 3-6 As shown, a first electromagnet 19 is fixedly connected to one side of the baffle plate 16, and a second electromagnet 20 is fixedly connected inside the discharge port 13.

[0036] In this embodiment, specifically: when the baffle plate 16 is used to close the discharge port 13, the second electromagnet 20 and the first electromagnet 19 can be activated, so that the second electromagnet 20 and the first electromagnet 19 generate an electromagnetic attraction force to each other, causing the first electromagnet 19 to drive the baffle plate 16 to slide into the sliding groove 15. When the first electromagnet 19 and the second electromagnet 20 are in mutual contact, the baffle plate 16 completely seals the discharge port 13. When discharging, the first electromagnet 19 and the second electromagnet 20 can also be activated in reverse, so that the first electromagnet 19 and the second electromagnet 20 generate a repulsive force between them, thereby pushing the baffle plate 16 back into the sliding groove 15.

[0037] like Figures 3-6 As shown, the bottom of the baffle plate 16 and the first electromagnet 19 are fixedly connected to the universal ball 18, and the inner bottom wall of the discharge port 13 is provided with a guide groove 17, and the universal ball 18 is slidably connected to the inside of the guide groove 17.

[0038] In this embodiment, specifically: when the baffle plate 16 moves by the attraction between the first electromagnet 19 and the second electromagnet 20, the movement of the baffle plate 16 and the first electromagnet 19 can be injected by the universal ball 18, and the movement direction of the guide groove 17, the baffle plate 16 and the first electromagnet 19 can be guided by the universal ball 18.

[0039] like Figure 1 As shown, both the first grinding seat 4 and the second grinding seat 5 are fixedly connected to the outside of the feed pipe 21, and the two feed pipes 21 are fixedly connected to the elastic rubber connecting section 22.

[0040] In this embodiment, specifically: during use, raw materials can be continuously fed into the feed inlet 12 through the feed pipe 21, and when the first grinding seat 4 and the second grinding seat 5 are separated, the feed pipe 21 can be deformed and stretched through the elastic rubber connecting section 22, thereby dividing the feed pipe 21 into two parts, which are separated together with the first grinding seat 4 and the second grinding seat 5.

[0041] Working principle: When starting the crushing operation, the operator continuously feeds the raw material to be crushed through the feed pipe 21. The raw material smoothly enters the grinding chamber 9 through the feed port 12. Then, the drive motor 8 starts and drives the grinding ball 10 to rotate in the grinding chamber 9 through the connecting rod 11. The inner wall of the grinding chamber 9 and the outer wall of the grinding ball 10 are specially treated to form a rough grinding surface. Under the rotation of the grinding ball 10, the raw material moves relative to the inner wall of the grinding chamber 9, thereby achieving preliminary grinding.

[0042] To further improve the grinding effect, two sets of hydraulic cylinders 7 can be activated to drive the first grinding seat 4 and the second grinding seat 5 to move closer to each other. During this process, the effective grinding gap of the grinding chamber 9 gradually decreases, and the squeezing effect of the inner wall of the grinding chamber 9 and the outer wall of the grinding ball 10 on the raw material is enhanced, which helps to achieve finer grinding and reduce the particle size distribution range of the crushed material. If the grinding chamber 9 becomes blocked during the grinding process, the hydraulic cylinder 7 can be activated again to separate the first grinding seat 4 and the second grinding seat 5 from each other. At this time, the grinding chamber 9 is divided into two semi-circular grinding cavities, and the blocked material is no longer in contact with the grinding ball 10 and the inner wall of the grinding chamber 9, making it easier to clean.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
