Description

Technical Field

[0001] This utility model relates to the field of flotation reagent reactor technology, and in particular to a feeding device for a flotation reagent reactor. Background Technology

[0002] Flotation reagents are chemical agents used in mineral processing to improve the efficiency of mineral flotation. Commonly used flotation reagents are divided into three main categories: collectors, frothers, and modifiers. Flotation reagents are mainly composed of surfactants and polymers, and their production process involves multiple steps, including raw material selection, polymerization reaction, and product purification. The production of flotation reagents first requires the selection of suitable raw materials; common raw materials include acrylamide and caprolactam. After pretreatment, the raw materials enter the reactor to begin the polymerization reaction stage. Polymerization is the process of forming high-molecular-weight polymers from monomeric raw materials through chemical reactions. For example, polyacrylamide is produced from acrylamide monomers through polymerization. After the polymerization reaction is complete, the product needs to be purified to remove impurities generated during the reaction, obtaining a purer product.

[0003] In the polymerization stage of a reactor, various materials need to be fed into the reactor, and then the stirring action of the reactor is used to thoroughly mix the materials to obtain a high molecular weight polymer. Existing reactors are generally top-feeding type, and thorough mixing relies entirely on stirring, which takes a long time. In addition, some chemical reactions require the introduction of sufficient air (oxygen), and many reactors do not have this function, at least not the ability to directly add air to the reactants to promote the reaction. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for a flotation agent reactor, so as to solve the problems of existing reactors where top feeding results in long mixing times and the inability to directly supplement the reactants with air to promote the reaction.

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

[0006] A feeding device for a flotation reagent reactor includes a raw material silo, a three-way valve, a water-air dual-purpose pump, and a feed pipe. The feed pipe is installed on the inner wall of the reactor. The discharge end of the water-air dual-purpose pump is connected to the inlet end of the feed pipe. The discharge end of the three-way valve is connected to the inlet end of the water-air dual-purpose pump. The liquid inlet end of the three-way valve is connected to the raw material silo. The air inlet end of the three-way valve is connected to the outside.

[0007] A further technical solution is that the material pipe is a flexible hose, and it is installed on the inner wall of the reactor through a U-shaped pipe clamp.

[0008] A further technical solution is that the feed pipe located inside the reactor is uniformly provided with multiple discharge ports.

[0009] A further technical solution is that the feed pipe has a U-shaped structure inside the reaction vessel.

[0010] A further technical solution is that the bottom of the material tube is provided with multiple discharge ports.

[0011] A further technical solution is that an air filter is provided at the air inlet end of the three-way fitting.

[0012] A further technical solution is that the three-way component is a three-way solenoid valve.

[0013] A further technical solution is that the three-way fitting is a three-way pipe, and both the liquid inlet end and the air inlet end of the three-way pipe are equipped with valves.

[0014] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0015] This invention proposes a feeding device for a flotation agent reactor. This device can directly feed external liquid raw materials into the lower part of the reactor. Especially in some production processes with a feeding sequence, the later raw materials can be pre-mixed with the earlier raw materials entering the reactor, reducing stratification and shortening the time for thorough mixing. After feeding is completed, the feeding can be stopped and external air can be pumped into the reactor. This allows the gas to directly enter the raw materials, promoting mixing, and also meets the needs of some reaction processes that require the addition of oxygen. Attached Figure Description

[0025] Example 1:

[0026] This implementation example Figure 1 As shown, a feeding device for a flotation reagent reactor includes a raw material silo 1, a three-way connector 2, a water-air dual-purpose pump 4, and a feed pipe 5. The feed pipe 5 is installed on the inner wall of the reactor 6. The discharge end of the water-air dual-purpose pump 4 is connected to the inlet end of the feed pipe 5. The discharge end of the three-way connector 2 is connected to the inlet end of the water-air dual-purpose pump 4. The liquid inlet end of the three-way connector 2 is connected to the raw material silo 1, and the air inlet end of the three-way connector 2 is connected to the outside.

[0027] The various raw materials to be produced are first stored in the raw material silo 1. Generally speaking, the number of storage chambers in the raw material silo 1 matches the type of raw material (generally liquid material). The outlets of each storage chamber in the raw material silo 1 are connected to the inlet of the three-way fitting 2. Each storage chamber outlet is also equipped with its own control valve.

[0028] The raw materials pass through the control valve and, under the action of the water-air dual-purpose pump 4, the liquid material enters the reactor 6 through the feed pipe 5. Under the stirring action of the reactor 6 itself, the materials can be mixed. Moreover, this device directly feeds the external liquid raw materials into the middle and lower part of the reactor 6. Especially for some production processes with a feeding sequence, the later raw materials can be pre-mixed with the earlier raw materials entering the reactor, reducing stratification and shortening the full mixing time. After the feeding is completed, the feeding can be stopped and external air can be pumped into the reactor. Firstly, the gas directly enters the inside of the raw materials, which has the effect of air surge to promote mixing. Secondly, it meets the needs of some reaction processes that require the addition of oxygen.

[0029] Preferably, the feed pipe 5 is a flexible hose and is installed on the inner wall of the reactor 6 via a U-shaped pipe clamp 7.

[0030] The flexible hose facilitates the layout inside the reactor 6 and is snapped into the U-shaped tube clamp 7, which is beneficial for the distribution of materials and introduced air inside the reactor 6.

[0031] Preferably, the feed pipe 5 located inside the reactor 6 is evenly provided with multiple discharge ports.

[0032] Liquid raw materials can be mixed relatively evenly with the raw materials in the reactor through multiple discharge ports.

[0033] Preferably, the feed pipe 5 has a U-shaped structure inside the reactor 6.

[0034] The U-shaped feed pipe 5 can adapt to the structure of the reactor 6 and can disperse the raw materials evenly.

[0035] Preferably, the bottom of the feed tube 5 is provided with multiple discharge ports.

[0036] Multiple discharge ports are located at the bottom of the feed pipe 5 to restrict the entry of new raw materials and ensure thorough mixing of new and old materials.

[0037] Preferably, the air inlet end of the three-way fitting 2 is provided with an air filter 8.

[0038] When introducing air to promote mixing and reaction of raw materials in the reactor, an air filter 8 can be used to prevent impurities from entering.

[0039] Preferably, the three-way component 2 is a three-way solenoid valve.

[0040] A three-way solenoid valve can automatically control the switching of the flow path.

[0041] Preferably, the three-way fitting 2 is a three-way pipe, and valves 3 are provided at both the liquid inlet end and the air inlet end of the three-way pipe.

[0042] The switching of the three-way pipe passage is achieved by using the opening and closing states of the two valves 3 respectively.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
