Description

Technical Field

[0001] This utility model relates to the field of fluid iron removal technology, specifically to an iron removal device inside a vessel. Background Technology

[0002] In chemical production, iron slag mixed in fluids can cause wear and tear on subsequent process equipment. To avoid this loss, iron removal from the fluid is necessary. Currently, iron removal is performed using iron separators. For example, Chinese Patent 202420076175.X discloses a fluid-type iron separator. This separator, through a connecting mechanism, utilizes a long-lasting (deep magnetic field) magnetic plate on the fluid pipe cover. When the fixed plate moves, it causes a block to insert into a square groove, allowing for the connection and installation of the fluid pipe and the fluid pipe cover, facilitating the removal of fine ferrous metal contaminants.

[0003] The existing technology has the following problems: outside the vessel, the fluid flows through the iron separator by a pump to remove iron. The pump flow rate is fast, which causes the fluid to have a certain scouring effect on the iron separator. Some of the foreign objects magnetically attracted on the iron separator will be washed away, resulting in a low iron removal rate. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose an iron removal device inside the vessel to solve the technical problem that the high flow rate of the pump in the prior art washes away some of the foreign objects magnetically attracted on the iron remover, resulting in a low iron removal rate.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] This utility model provides an iron removal device for a reactor body, comprising:

[0007] The vessel body;

[0008] An annular hopper, built into the inner side of the vessel body, is used to collect iron slag; and

[0009] The iron removal assembly includes an electromagnetic rod and a lifting mechanism. The lifting mechanism is installed on the vessel body and its movable end is connected to the electromagnetic rod to drive the electromagnetic rod to move up and down, so that it has an iron removal position where it is inserted below the liquid surface and is attracted by electromagnetic force, and a slag removal position where it is raised to the liquid surface and moved to the annular bucket and demagnetized by power failure.

[0010] In some embodiments, the annular hopper includes an annular trough and an inclined box. The annular trough is disposed on the inner wall of the vessel body, and the inclined box is disposed on the inner side of the annular trough and communicates with the annular trough. The inner bottom wall of the inclined box is inclined downward toward the annular trough to allow iron slag to slide toward the annular trough at the slag removal position.

[0011] In some embodiments, the top of the inclined box is provided with a slag removal hole, and the bottom of the inclined box is provided with a through hole. The electromagnetic rod passes through the through hole and the slag removal hole from bottom to top. The inner wall of the slag removal hole is in contact with the outer surface of the electromagnetic rod, and is used to push the iron slag downward when the electromagnetic rod moves upward. The bottom end of the electromagnetic rod is provided with a sealing plug, which is inserted into the through hole when the slag removal position is in place.

[0012] In some embodiments, when the sealing plug is in the slag removal position, it is flush with the inner bottom wall of the inclined box.

[0013] In some embodiments, the number of electromagnetic rods in the iron removal assembly is multiple, and the multiple electromagnetic rods are connected to the movable end of the lifting mechanism through a ring frame.

[0014] In some embodiments, the number of the iron removal components is at least two sets, and one set of the iron removal components is located at the iron removal position, while the other set of the iron removal components is located at the slag removal position.

[0015] In some embodiments, the electromagnetic rods on the two sets of iron removal components are distributed sequentially at intervals.

[0016] In some embodiments, the annular frames on the two sets of iron removal assemblies are arranged in concentric circles.

[0017] In some embodiments, a slag blowing assembly is further included, having a plurality of blowing nozzles, each corresponding to an electromagnetic rod, for blowing inert gas at the slag removal position to blow iron slag downward along the inner bottom wall of the inclined box.

[0018] In some embodiments, the slag blowing assembly includes an annular pipe, an air supply pipe, and an air jet pipe. The air jet nozzles are arranged one-to-one at the bottom end of the air jet pipe, the top end of the air jet pipe is connected to the annular pipe, one end of the air supply pipe is connected to the annular pipe, and the other end of the air supply pipe is connected to an air supply device.

[0019] Compared with the prior art, the iron removal device inside the vessel provided by this utility model, by setting an annular bucket and iron removal components inside the vessel, utilizes the slow flow rate of the fluid inside the vessel, and with the help of an electromagnetic rod that can switch between the iron removal position and the slag removal position, effectively removes iron from the fluid and concentrates iron slag, avoiding the situation where the foreign matter magnetically attracted on the iron remover is washed away due to the excessive flow rate, thereby improving the iron removal rate.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] To address the technical problem that high pump flow rates wash away some foreign objects magnetically attracted to the iron separator, resulting in low iron removal rates, this invention provides an iron removal device for a vessel interior, which can effectively remove iron under slow-speed fluid conditions within the vessel interior.

[0025] Please see Figure 1-3 This utility model provides an iron removal device inside a reactor, which includes a reactor body 1, an annular hopper 2, and an iron removal assembly 3. The annular hopper 2 is built inside the reactor body 1 and is used to collect iron slag. Its installation position is above the liquid surface inside the reactor body 1, and the annular shape has a hollow space in the middle to avoid interference with the stirring elements required by the reactor itself. The iron removal assembly 3 includes an electromagnetic rod 31 and a lifting mechanism 32. The lifting mechanism 32 is installed on the reactor body 1, and its movable end is connected to the electromagnetic rod 31. It is mainly used to drive the electromagnetic rod 31 to rise and fall, so that it has an iron removal position where it is inserted below the liquid surface and is attracted by electromagnetic force, and a slag removal position where it is raised to the liquid surface and moved to the annular hopper 2 and is demagnetized by power failure.

[0026] In this embodiment, when the electromagnetic rod 31 is inserted below the liquid surface, it is energized and magnetic, thus adsorbing iron slag in the fluid to achieve an iron removal effect. Since the fluid in the vessel does not have a high impact velocity, the adsorption of the electromagnetic rod 31 is relatively stable and unlikely to be washed away by the fluid. To avoid excessive iron slag adsorption affecting subsequent iron removal, a slag removal position is also provided. At this position, the electromagnetic rod 31 is moved above the annular hopper 2 under the drive of the lifting mechanism 32. At this point, the power is cut off, demagnetizing the electromagnetic rod 31 and causing it to lose its magnetic attraction. The iron slag then falls into the annular hopper 2 and is collected. The electromagnetic rod 31 is then moved below the liquid surface to continue iron removal, thus maintaining a better iron removal state.

[0027] In one embodiment, please refer to Figure 1 and Figure 3To guide the concentrated collection of iron slag, the annular hopper 2 includes an annular trough 21 and an inclined box 22. The annular trough 21 is disposed on the inner wall of the vessel body 1, and the inclined box 22 is disposed on the inner side of the annular trough 21 and communicates with the annular trough 21. The position and number of inclined boxes 22 correspond one-to-one with the electromagnetic rods 31. When the electromagnetic rods 31 move to the inclined box 22, the power is cut off and the magnetism is deactivated. The fallen iron slag falls onto the inner bottom wall of the inclined box 22. Under the downward inclination of the inner bottom wall of the inclined box 22 towards the annular trough 21, the iron slag slides towards the annular trough 21 at the slag removal position for concentrated collection.

[0028] Furthermore, to prevent iron slag from adhering to the electromagnetic rod 31 after power failure and demagnetization, the top of the inclined box 22 is provided with a slag removal hole 2201, and the bottom of the inclined box 22 is provided with a through hole 2202. The electromagnetic rod 31 passes through the through hole 2202 and the slag removal hole 2201 sequentially from bottom to top. The through hole 2202 allows the electromagnetic rod 31 and the iron slag on it to pass through, while the inner wall of the slag removal hole 2201 is fitted to the outer surface of the electromagnetic rod 31 for the electromagnetic rod to pass through. When the slag moves upward, it pushes the iron slag downward, thus concentrating the iron slag near the bottom of the electromagnetic rod 31 and preventing it from adhering to the electromagnetic rod 31 over a large area. At the same time, the bottom of the electromagnetic rod 31 is provided with a sealing plug 3101. When the slag is removed, the sealing plug 3101 is inserted into the through hole 2202, thereby closing the gap between the through hole 2202 and the electromagnetic rod 31. When the power is turned off and the magnetization is demagnetized, it can prevent the slag from falling back into the fluid through the gap during the removal process.

[0029] Furthermore, when the sealing plug 3101 is in the slag removal position, it is flush with the inner bottom wall of the inclined box 22, so that when it is flush with the wall, the falling iron slag can slide down.

[0030] Understandably, the lifting mechanism 32 can be a hydraulic telescopic rod. The telescopic end of the hydraulic telescopic rod is the movable end of the lifting mechanism 32. This end penetrates downward through the vessel body 1 into the interior of the vessel body 1 and is connected to the electromagnetic rod 31.

[0031] In one embodiment, please refer to Figure 1 and Figure 3 To avoid excessive residual iron slag on the inner bottom wall of the inclined box 22, the iron removal device inside the vessel also includes a slag blowing assembly 4. The slag blowing assembly 4 has multiple blowing nozzles 401, which correspond one-to-one with the electromagnetic rod 31. At the slag removal position, inert gas is blown to blow the iron slag down along the inner bottom wall of the inclined box 22, thereby blowing the iron slag that has fallen onto the inner bottom wall of the inclined box 22 downward toward the annular groove 21.

[0032] Specifically, the slag blowing assembly 4 includes an annular pipe 41, an air supply pipe 42, and an air jet pipe 43. Each air jet nozzle 401 is correspondingly located at the bottom end of the air jet pipe 43. The top end of the air jet pipe 43 is connected to the annular pipe 41. One end of the air supply pipe 42 is connected to the annular pipe 41, and the other end is connected to an air supply device. The air supply device can use a gas tank, an air pump, or an electrically controlled valve to supply air. When air is needed for blowing, the electrically controlled valve is opened, the air pump is started, and inert gas is drawn from the gas tank, pressurized, and delivered to the air jet pipe 43, where it is ejected from the air jet nozzle 401. Alternatively, a high-pressure gas tank can be used directly. After opening the valve of the high-pressure gas tank, high-pressure gas can be discharged to the air jet pipe 43 and ejected from the air jet nozzle 401. Other mechanisms capable of providing inert gas blowing can also be used; existing mature technologies are sufficient and will not be elaborated upon here.

[0033] In one embodiment, please refer to Figure 1 and Figure 2 In order to efficiently remove iron from the fluid inside the vessel 1, the number of electromagnetic rods 31 in the iron removal assembly 3 is multiple. The multiple electromagnetic rods 31 are connected to the movable end of the lifting mechanism 32 through the ring frame 33 and are distributed in a circumferential manner, which can remove iron with a large coverage area.

[0034] Furthermore, to avoid the problem of a single iron removal component 3 failing to remove iron in the fluid while in the slag removal position, and the iron slag falling back into the fluid during the slag removal process without being removed, thus causing a decrease in the iron removal rate, the number of iron removal components 3 is at least two sets, with one set of iron removal components 3 located in the iron removal position and the other set in the slag removal position. This ensures that while one set is removing slag, the other set is still removing iron below the fluid surface, maintaining an uninterrupted iron removal operation. This avoids the problems of interrupted iron removal and iron slag falling back into the fluid without being removed, thus preventing a decrease in the iron removal rate.

[0035] Furthermore, in order to remove iron evenly, the electromagnetic rods 31 on the two sets of iron removal components 3 are distributed at intervals in sequence.

[0036] Furthermore, in order to upgrade the height simultaneously, the annular frames 33 on the two sets of iron removal components 3 are arranged in concentric circles.

[0037] To better understand this utility model, the following is combined with... Figures 1 to 3The technical solution of this utility model is described in detail as follows: In the initial state, the electromagnetic rods 31 of both sets of iron removal components 3 are inserted below the fluid surface to remove iron. After a period of iron removal, the electromagnetic rods 31 on one set of iron removal components 3 are lifted. During the lifting process, the slag removal hole 2201 pushes the iron slag on the electromagnetic rods 31 downwards until the sealing plug 3101 is inserted into the through hole 2202. Then, the electromagnetic rods 31 are de-energized and demagnetized, and the slag blowing component 4 is activated at the same time to blow the slag towards the inclined box 22. With the help of the inclined surface of the bottom wall of the inclined box 22, the iron slag is concentrated into the annular tank 21. After slag removal, the electromagnetic rods 31 are lowered by the lifting mechanism 32 and reinserted below the fluid surface to be energized and magnetically removed. Then, the other set of iron removal components 3 is switched to the slag removal position, and the two sets of iron removal components 3 are used alternately.

[0038] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
