Description

Technical Field

[0001] This utility model relates to the field of hydrocyclone separation equipment technology, and more specifically, to a hydrocyclone separation equipment for automotive urea solution. Background Technology

[0002] Cyclone separation of automotive urea solution is a physical purification technology that uses a pumped liquid into a cyclone separator to generate high-speed centrifugal force, thereby rapidly and efficiently separating high-density solid impurities (such as insoluble matter, metal particles, etc.) from the pure liquid during the urea solution production process.

[0003] Currently, the underflow diameter of hydrocyclones is fixed, which makes it impossible to maintain the optimal "umbrella-shaped" discharge state when the feed pressure and impurity concentration fluctuate. This can easily lead to excessive loss of clean solution (rope flow) or blockage.

[0004] To address the aforementioned issues, this application proposes a hydrocyclone separator for automotive urea solutions. Utility Model Content

[0005] The purpose of this invention is to provide a hydrocyclone separator for automotive urea solution, which solves the problems of easy carryover of clean solution and blockage in the discharge process of existing technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] A hydrocyclone separator for automotive urea solution includes a hydrocyclone and a feeding pipe on its side, as well as a conical cylinder and an underflow pipe installed below the hydrocyclone.

[0008] It also includes a detachable and adjustable feeding mechanism;

[0009] The adjustable discharge mechanism includes a valve seat and a double-layer ring frame;

[0010] The upper end of the valve seat is provided with a conical seat, and the inner side of the conical seat is provided with a conical groove aligned with the inner surface of the conical cylinder;

[0011] The conical seat has a valve core that slides coaxially inside, and an elastic diaphragm is fixed inside the conical seat. The lower end of the elastic diaphragm is rigidly connected to the upper end of the valve core.

[0012] The double-layer ring frame includes an inner ring frame and an outer ring frame, which are located on the outer and inner sides of the underflow pipe, respectively. The inner side of the inner ring frame is threadedly connected to the outer side of the lower end of the underflow pipe.

[0013] Preferably, the outer side of the upper half of the conical seat is a cylindrical structure, housed inside the inner annular groove opened on the inner side of the lower end of the underflow pipe.

[0014] Preferably, a washer is provided between the top of the conical seat and the upper end face of the inner ring groove.

[0015] Preferably, the elastic diaphragm has connecting rods at both its upper and lower ends, which are fixedly connected to the washer and the elastic diaphragm, respectively.

[0016] Preferably, the bottom of the valve core has a positioning hole and is sleeved on the outside of the column at the center of the valve seat.

[0017] Preferably, the lower outer side of the column is provided with a support rod that is fixedly connected to the inner wall of the valve seat.

[0018] Preferably, the cross-section of the elastic diaphragm is an oblique sheet with a higher inner section and a lower outer section, and the whole has a spiral structure.

[0019] The beneficial effects of this utility model are:

[0020] 1. By using the elastic expansion and contraction of the elastic diaphragm, the valve core is driven to slide up and down by the pressure above, thereby achieving the effect of adjusting the distance between the outer surface of the valve core and the inner surface of the conical seat in real time according to the pressure, thereby controlling the opening size of the bottom flow port, so that the discharge state is always kept in the optimal "umbrella" shape.

[0021] 2. By screwing the outer ring frame to the underflow pipe, the inner ring frame applies a tightening force to the underflow pipe, so that the inner surface of the conical cylinder and the conical seat can be easily aligned. This makes it convenient to disassemble and replace the conical seat with the most wear, and also convenient to clean and maintain. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] A cyclone separator for automotive urea solution is designed to maintain optimal discharge conditions under different pressures. By changing the pressure of the pumped material, the gasket 25 is stretched or retracted accordingly, thereby causing the valve core 23 to rise or fall. This adjusts the opening between the valve core 23 and the conical seat 211, achieving convenient adjustment of the underflow port size. Furthermore, the valve seat 21 and its internal valve core 23 can be easily removed and placed through the assembly and disassembly of the double-layer ring frame 22, facilitating cleaning, maintenance, and replacement.

[0033] In some embodiments, the specific structure of the automotive urea solution hydrocyclone separator is as follows: Figure 1-5 As shown, the cyclone separator and the discharge mechanism with adjustable underflow outlet;

[0034] The hydrocyclone separator includes a hydrocyclone 11 and a feed pipe 12 on one side. A conical cylinder 13 and an underflow pipe 14 at the lower end of the hydrocyclone 11 are installed through a flange.

[0035] The discharge mechanism includes a valve seat 21 and a double-layer ring frame 22;

[0036] Valve seat 21 is a vertical cylindrical structure with a conical seat 211 fixedly installed at the upper end;

[0037] The outer part of the conical seat 211 is a cylindrical structure, and the inner part is a conical hole structure with a larger upper part and a smaller lower part. The conical surface is aligned with the inner conical surface of the conical cylinder 13.

[0038] Furthermore, an annular groove, called an inner annular groove 141, is provided on the inner side of the lower end of the underflow pipe 14 to accommodate the body of the conical seat 211.

[0039] Furthermore, a valve core 23 is longitudinally slidably installed inside the conical seat 211. Its upper end is divided into a pointed cone structure with a smaller upper end and a larger lower end, and its lower end is divided into a conical platform structure with a larger upper end and a smaller lower end. The slope of the conical platform is the same as the slope of the conical surface of the conical seat 211.

[0040] Among them, the upper end of the valve core 23 is provided with an elastic diaphragm 24, the upper end of which is fixed to the top of the conical seat 211, and the lower end is rigidly connected to the pointed cone of the valve core 23, forming a spiral plate structure with the upper and lower ends fixed and the middle section elastically deformable.

[0041] It is understandable that when the pressure on the elastic diaphragm 24 increases, it produces a stretching elastic deformation, which causes the valve core 23 to descend. As the valve core 23 descends, its outer side approaches the inner side of the conical seat 211 and shortens the gap. Conversely, it can drive the valve core 23 to expand the gap up and down, thereby achieving the effect of adjusting the size of the bottom flow port.

[0042] The double-layer ring frame 22 includes an outer inner ring frame 221 and an inner outer ring frame 222.

[0043] The inner side of the inner ring frame 221 is threaded and screwed to the thread machined on the outer side of the lower end of the underflow pipe 14 to control the up and down movement of the double ring frame 22.

[0044] Furthermore, the lower end of the outer ring frame 222 is fixedly connected to the lower end of the inner ring frame 221, and the upper end of the outer ring frame 222 abuts against the lower end face of the inner ring frame 221. As the inner ring frame 221 rises, it pushes the inner ring frame 221 upward, thereby achieving the effect of fixing the inner ring frame 221.

[0045] It should be noted that the outer side of the inner ring frame 221 is a cylindrical structure. The cylindrical mechanism is located in the upper half of the inner ring frame 221, and its lower end face forms a horizontal end face for docking with the outer ring frame 222.

[0046] like Figure 2 As shown in the figure, a vertical rod, known as column 212, is installed at the center of valve seat 21;

[0047] Among them, a radially vertical support rod 2121 is fixedly installed on the outer side of the lower end of the column 212, forming a fixed connection with the valve seat 21;

[0048] Furthermore, a positioning hole 231 is provided at the lower center of the valve core 23 for docking with the column 212 and limiting the sliding path.

[0049] like Figure 3 and Figure 4 As shown, a washer 25 is clamped and fixed between the top of the connecting rod 241 and the upper end face of the inner ring groove 141 to form a seal to prevent solution and impurities from entering the gap.

[0050] It should be noted that gasket 25 is preferably made of EPDM rubber or fluororubber to enhance corrosion resistance;

[0051] like Figure 3 and Figure 5 As shown, connecting rods 241 are fixedly installed at both the upper and lower ends of the elastic diaphragm 24. The upper connecting rod 241 is fixedly connected to the washer 25, and the lower connecting rod 241 is fixedly connected to the cone of the elastic diaphragm 24.

[0052] It should be noted that under normal conditions, the elastic diaphragm 24 is in a pre-open state, that is, it is slightly stretched under pressure. When the pressure decreases, it can drive the valve core 23 to rise.

[0053] The specific usage methods of automotive urea solution hydrocyclone separators, as disclosed in some publications, are as follows:

[0054] S1. Place the washer 25 on the upper end of the conical seat 211 and push the valve seat 21 upward so that the washer 25 is clamped between the upper end face of the inner annular groove 141 and the upper end face of the conical seat 211.

[0055] S2. Screw the inner thread of the inner ring frame 221 onto the thread on the outer side of the lower end of the underflow pipe 14, so that the outer ring frame 222 pushes the inner ring frame 221 up, thereby clamping the washer 25 to form a seal. At this time, the elastic diaphragm 24 is fixed between the valve core 23 and the washer 25.

[0056] S3. Material is pumped into the cyclone drum 11 through the feed pipe 12 to form a cyclone. The downward swirling slurry exerts pressure on the elastic diaphragm 24. When the pressure is greater than a predetermined value, the elastic diaphragm 24 is stretched, causing the valve core 23 to descend. At this time, the distance between the outer surface of the valve core 23 and the inner surface of the conical seat 211 decreases. When the pressure is less than the predetermined value, the elastic diaphragm 24 retracts, causing the valve core 23 to rise. At this time, the distance between the outer surface of the valve core 23 and the inner surface of the conical seat 211 increases. This achieves the effect of automatically adjusting the size of the underflow outlet according to the slurry pressure.

[0057] S4. By rotating the double-layer ring frame 22 downwards, the limiting effect on the conical seat 211 is released, allowing the valve seat 21 and gasket 25 to directly descend into the area. At this point, cleaning and maintenance can be performed, and the vulnerable component can be replaced.
