Description

Technical Field

[0001] This utility model relates to the field of polyaluminum chloride technology, specifically to a polyaluminum chloride discharge port anti-blocking device. Background Technology

[0002] Polyaluminum chloride, as a highly efficient inorganic polymeric coagulant, has been widely used in drinking water purification, industrial wastewater treatment, paper sizing, and dyeing wastewater decolorization due to its excellent flocculation and sedimentation performance.

[0003] In the industrial production process of polyaluminum chloride, the material after the polymerization reaction in the reactor needs to be discharged through the bottom discharge port to enter subsequent drying, crushing, and packaging processes. However, polyaluminum chloride itself has the physical characteristics of being hygroscopic and prone to caking when exposed to temperature. As the material temperature gradually decreases from the high reaction temperature to room temperature after the reaction, if the discharge is not timely or there is residue in the discharge port, the material is very likely to adhere to the inner wall of the discharge port and form hard lumps. At the same time, most existing reactor discharge ports adopt a simple straight-cylinder structure, lacking a targeted anti-clogging design, and rely solely on the material's own gravity for feeding. Once lumps of material appear, they will get stuck in the narrow channel of the discharge port, causing blockage.

[0004] Currently, the industry mostly uses temporary measures to address this type of blockage, such as manually tapping the outer wall of the discharge port periodically or installing a simple vibrating motor on the outside of the discharge port. However, the former cannot fundamentally solve the blockage caused by clumps and may even damage the equipment. While the latter can alleviate local blockages through vibration, the vibration intensity is difficult to control precisely. If the intensity is too low, it will not be able to break up the hard clumps, while if the intensity is too high, it may cause the connection between the discharge port and the reactor to loosen, thereby increasing the risk of material leakage.

[0005] In summary, the lack of anti-clogging design in existing reactor discharge ports has become a key bottleneck restricting the improvement of polyaluminum chloride production efficiency, increasing production costs, and raising safety risks. Developing a stable and reliable anti-clogging device for polyaluminum chloride discharge ports has become an urgent need in the industry. Therefore, this paper proposes an anti-clogging device for polyaluminum chloride discharge ports. Summary of the Invention

[0006] The purpose of this invention is to provide a device for preventing blockage at the discharge port of polyaluminum chloride, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a polyaluminum chloride discharge port anti-clogging device, comprising a cylinder body, the cylinder body being installed at the bottom of a reaction vessel, an outer cylinder being coaxially installed on the outer side of the cylinder body, a rotating cylinder that can rotate and move up and down being sleeved between the outer cylinder and the cylinder body, and a plurality of stirring rods being installed on the inner bottom of the rotating cylinder, the plurality of stirring rods being located on the inner side of the cylinder body;

[0008] Two inclined plates are installed on the outer side of the rotating cylinder, and a guide groove is provided between the two inclined plates. A driving component is installed on the outer side of the cylinder, and a driving block is installed on the piston rod of the driving component. A driving rod is installed on one side of the driving block, and one end of the driving rod passes through the outer cylinder and is located inside the guide groove.

[0009] Preferably, the bottom of the outer cylinder is bolted with a sealing plate to prevent premature material discharge.

[0010] Preferably, the outer cylinder has a through groove on its outer side to facilitate the movement of the drive rod, and the through groove is vertically opened along the height direction of the outer cylinder.

[0011] Preferably, the driving component is a hydraulic cylinder, a pneumatic cylinder, or an electric telescopic rod, and the driving component is fixed to the outside of the cylinder by a bracket.

[0012] Preferably, the top of the stirring rod is lower than the top of the cylinder.

[0013] Preferably, the outer side of the rotating cylinder is provided with an inwardly recessed concave bending portion, and the two inclined plates are located inside the concave bending portion.

[0014] Preferably, the bottom of the cylinder is provided with a folded edge for supporting the rotating cylinder, and the concave bending part is located above the folded edge.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: The device drives the drive rod to move up and down through the drive component. With the cooperation of the guide groove and the drive rod, linear motion is converted into the rotation and up-and-down movement of the drum, which in turn drives the stirring rod to move synchronously inside the drum. This breaks up hardened lumps and prevents materials from adhering and accumulating on the inner wall of the discharge port. Compared with the traditional method of manual knocking which only treats the symptoms but not the root cause, or the problem of simple vibration force being difficult to control, this method provides more thorough anti-blockage and effectively ensures unobstructed discharge channels.

[0023] 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.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a polyaluminum chloride discharge port anti-clogging device, including a cylinder 1. The cylinder 1 is fixedly installed at the bottom discharge port of the reactor by a flange or bolts. The inner cavity of the cylinder 1 is connected to the discharge channel of the reactor to ensure that the polyaluminum chloride material in the reactor can smoothly enter the cylinder 1. An outer cylinder 2 is coaxially sleeved on the outer side of the cylinder 1. The top of the outer cylinder 2 is fixedly connected to the middle of the outer side wall of the cylinder 1 by welding or an annular bracket, so that an annular movable gap is formed between the outer cylinder 2 and the cylinder 1.

[0025] A rotating cylinder 8 is fitted inside the annular gap between the outer cylinder 2 and the cylinder body 1. The inner diameter of the rotating cylinder 8 is slightly larger than the outer diameter of the cylinder body 1, and the outer diameter is slightly smaller than the inner diameter of the outer cylinder 2, ensuring that the rotating cylinder 8 can rotate and move up and down within the annular gap. Multiple stirring rods 5 are fixedly installed on the inner bottom of the rotating cylinder 8. The stirring rods 5 extend into the inner cavity of the cylinder body 1 so that when the rotating cylinder 8 moves, it drives the stirring rods 5 to rotate inside the cylinder body 1, stirring and dispersing the polyaluminum chloride material inside the cylinder body 1, and preventing the material from clogging the inner cavity of the cylinder body 1.

[0026] Two inclined plates 7 are welded and fixedly installed on the middle of the outer wall of the rotating cylinder 8. The two inclined plates 7 have the same inclination angle and form a guide groove 71 between them. The width of the guide groove 71 matches the diameter of the drive rod 31 to ensure that the drive rod 31 can slide smoothly in the groove. A drive component 4 is fixedly installed on the outer wall of the cylinder 1 by a bracket. One side of the bracket is welded to the outer wall of the cylinder 1, and the other side is fixedly connected to the cylinder or housing of the drive component 4 by bolts to ensure that the drive component 4 is installed firmly. A drive block 3 is installed on the top of the piston rod of the drive component 4. A drive rod 31 is fixed on one side of the drive block 3 perpendicular to the piston rod direction. One end of the drive rod 31 penetrates the side wall of the outer cylinder 2 and extends into the guide groove 71, and the drive rod 31 and the guide groove 71 are in sliding fit. When the driving component 4 drives the piston rod to extend and retract up and down, the piston rod drives the driving block 3 and the driving rod 31 to move up and down synchronously. The driving rod 31, through sliding cooperation with the guide groove 71, converts the vertical linear motion into a composite motion of circumferential rotation and axial vertical movement of the rotating drum 8, thereby driving the stirring rod 5 to achieve anti-clogging stirring.

[0027] like Figure 2 As shown: A sealing plate 6 is detachably installed at the bottom port of the outer cylinder 2 by multiple circumferentially distributed bolts. The function of the sealing plate 6 is to prevent polyaluminum chloride material from leaking out prematurely during the production and processing. After processing is completed, the sealing plate 6 can be removed by unscrewing the bolts, so that the material can be discharged smoothly.

[0028] like Figure 1 and Figure 2 As shown: A through groove 9 is provided on the outer wall of the outer cylinder 2 corresponding to the position of the drive rod 31. The through groove 9 is vertically opened along the height direction of the outer cylinder 2, and the width of the through groove 9 is slightly larger than the diameter of the drive rod 31. This through groove 9 provides a channel for the drive rod 31 to move up and down, avoiding the outer cylinder 2 side wall from obstructing the movement of the drive rod 31. At the same time, the vertical design of the through groove 9 ensures that the drive rod 31 moves only along the axial direction without additional offset, ensuring the fitting accuracy with the guide groove 71.

[0029] like Figure 1 As shown: the drive component 4 can be any one of a hydraulic cylinder, a pneumatic cylinder, or an electric telescopic rod; when it is a hydraulic cylinder, it obtains power by connecting to an external hydraulic system through a hydraulic pipeline. When it is a pneumatic cylinder, it is connected to an external air source through an air pipe. When it is an electric telescopic rod, it is connected to an external power source and controller through a wire. The drive component 4 is fixed to the outside of the cylinder 1 by a bracket.

[0030] like Figure 5 As shown: The top height of the stirring rod 5 is lower than the top height of the cylinder 1. This design can prevent the top of the stirring rod 5 from protruding from the cylinder 1, so as not to obstruct the material in the reactor from falling into the cylinder 1 and ensure smooth feeding. At the same time, the top height of the stirring rod 5 can still cover the main accumulation area of ​​the material in the cylinder 1, ensuring that the stirring and anti-clogging effect is not compromised.

[0031] like Figure 5 As shown: The outer wall of the rotating cylinder 8 is integrally formed with an inwardly recessed concave bending portion 81. The concave bending portion 81 is an annular structure extending circumferentially along the rotating cylinder 8, and its recess depth is adapted to the thickness of the inclined plate 7. The two inclined plates 7 are fixedly installed in the inner recessed space of the concave bending portion 81 by welding.

[0032] like Figure 5 As shown: The bottom outer wall of the cylinder 1 is integrally formed with an outwardly horizontally bent edge 11. The edge 11 is an annular structure and its top surface is a horizontal support surface. The bottom end face of the concave bending part 81 contacts the top surface of the edge 11. The edge 11 provides axial support for the rotating cylinder 8 and prevents the rotating cylinder 8 from falling out of the annular gap under the action of gravity.

[0033] Working principle: First, the sealing plate 6 is installed at the bottom of the outer cylinder 2 with bolts to prevent premature leakage of polyaluminum chloride material during processing. At this time, the concave bending part 81 on the rotating cylinder 8 rests on the folded edge part 11 at the bottom of the cylinder 1. The folded edge part 11 provides axial support for the rotating cylinder 8 and prevents it from falling off.

[0034] When it is necessary to prevent material blockage, the drive component 4, which is fixed to the outside of the cylinder 1, is activated. The drive component 4 drives the drive block 3 and drive rod 31 connected to it to move together. The drive rod 31 slides up and down along the vertical through groove 9 opened on the side wall of the outer cylinder 2. Since one end of the drive rod 31 extends into the guide groove 71 and the drive rod 31 and the guide groove 71 are in sliding fit, when the drive rod 31 moves up and down, it will exert a force on the guide groove 71 in the inclined direction of the inclined plate 7. This force causes the rotating cylinder 8 to rotate circumferentially and move up and down simultaneously within the annular gap between the cylinder 1 and the outer cylinder 2.

[0035] Multiple stirring rods 5 are installed at the bottom inner side of the rotating drum 8, located inside the drum body 1. The movement of the rotating drum 8 directly drives the stirring rods 5 to rotate synchronously and move up and down within the inner cavity of the drum body 1. During the movement, the stirring rods 5 stir and disperse the polyaluminum chloride material inside the drum body 1, breaking the tendency of the material to clump together and preventing the material from accumulating and clogging inside the drum body 1.

[0036] 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.
