Description

Technical Field

[0001] This utility model relates to the technical field of agitator devices, and in particular to an agitator for coating titanium dioxide. Background Technology

[0002] Titanium dioxide (TiO2) is an important white inorganic pigment widely used in coatings, plastics, and papermaking industries. However, titanium dioxide itself has some inherent defects, such as a tendency to lose gloss, yellowing, and discoloration, leading to reduced weather resistance. Therefore, a common practice is to coat titanium dioxide, and this coating process is a key step in improving its performance. For example, coating can improve the weather resistance and dispersibility of titanium dioxide. Currently, the performance of the agitator directly affects the coating effect during the titanium dioxide coating process. Existing agitators have several problems, such as uneven mixing leading to uneven coating on the surface of titanium dioxide particles, affecting product quality; low mixing efficiency and long coating time, increasing production costs; noise generation during mixing, affecting the working environment; and the tendency for coating slurry residue to remain inside the agitator, making cleaning difficult and affecting subsequent production.

[0003] CN209741051U discloses an inorganic coating device for rutile titanium dioxide, comprising a shell, an acidic salt storage chamber, an alkaline solution storage chamber, a stirrer, a flow guide, a heater, a controller, and an observation window; the stirrer for titanium dioxide coating is located at the center of the shell, the acidic salt storage chamber is located on one side of the top of the shell, the alkaline solution storage chamber is located on the opposite side of the acidic salt storage chamber, the acidic salt storage chamber and the alkaline solution storage chamber are respectively connected to the flow guide, the flow guide is located inside the shell and is sleeved outside the rotating shaft of the stirrer, the heater is located on the inner side wall of the shell, the observation window is located on the side wall of the shell, and the controller is located on the outer wall of the shell. While this technical solution addresses some of the issues—such as the accumulation of chemicals at the water outlet leading to incomplete chemical reaction, poor titanium dioxide coating effect, and low coating efficiency—it does not address the cleaning of residual coating slurry within the device. This residual coating slurry will accumulate over time, and failure to clean it in a timely manner or inadequate cleaning will affect subsequent production, further reducing the coating effect of titanium dioxide.

[0004] CN214346296U discloses an apparatus for preparing titanium dioxide, including a high-temperature and high-pressure reactor. The reactor is equipped with a level gauge, thermometer, pressure gauge, discharge pipe, and drain pipe. A liquid pump is installed on the discharge pipe, and the pump is connected to a heat exchange assembly and a self-circulating cleaning mechanism via branch pipes. The discharge end of the heat exchange assembly is connected to a dewatering process. The self-circulating cleaning mechanism includes a filter and a second heat exchange assembly. The filter residue outlet is connected to the dewatering process, and the filter filtrate outlet is connected to the inlet of the second heat exchange assembly. The discharge end of the second heat exchange assembly is connected to the inlet of the high-temperature and high-pressure reactor. While this technical solution solves the aforementioned cleaning difficulties, the filter body and the high-temperature and high-pressure reactor are not integrated. The cleaning agent needs to be transported to the filter after cleaning using the existing stirring paddle inside the reactor. Since the internal structure of the reactor is not modified, cleaning dead zones still exist inside the reactor.

[0005] Based on the above, existing technologies have several technical problems that urgently need to be solved, such as the inability of titanium dioxide coating devices to simultaneously achieve good coating effect, thorough cleaning of residual coating slurry inside the agitator, and thorough cleaning. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a stirrer for coating titanium dioxide, including a stirring tank, a stirring component, a cleaning component, and a coating agent feeding component; The cleaning assembly includes a connecting seat, a plurality of water nozzles disposed on the connecting seat, a baffle located outside the water nozzles, and an elastic component connecting the baffle located inside the connecting seat; the baffle and the connecting seat are movably connected.

[0007] Furthermore, during the mixing of titanium dioxide and coating agent by the agitator for titanium dioxide coating, the baffle blocks the water spray nozzle due to the tightening effect of the elastic component, preventing titanium dioxide, coating agent, or coated slurry from entering the cleaning assembly; when cleaning the agitator for titanium dioxide coating, the cleaning agent is introduced into the connecting seat through the connector, the pressure in the connecting seat increases, the elastic component stretches, the baffle moves away from the water spray nozzle, and the cleaning agent is sprayed from the water spray nozzle into the mixing tank to clean the agitator for titanium dioxide coating. The agitator for titanium dioxide coating achieves self-cleaning and anti-clogging design by setting a dynamic water spray cleaning component. Specifically, the water spray nozzle adopts a structure that combines elastic components and baffles. It closes during agitation to prevent slurry from entering, and automatically opens hydraulically during cleaning to achieve residue-free spray cleaning.

[0008] Furthermore, a cleaning agent flow meter is installed on the connector. The higher the flow rate of the cleaning agent, the greater the pressure within the connector, and the greater the distance of the baffle from the spray nozzle. Conversely, the lower the flow rate of the cleaning agent, the lower the pressure within the connector, and the smaller the distance of the baffle from the spray nozzle. When no cleaning agent is supplied to the connector, the baffle, due to the tightening effect of the elastic component, fits tightly against the outside of the spray nozzle. That is, the cleaning agent flow rate and the baffle opening are linked, precisely controlling the cleaning coverage area.

[0012] Furthermore, the cleaning assembly also includes a cleaning scraper, which is detachably mounted on the connecting seat and positioned above the liquid surface inside the titanium dioxide coating agitator to clean the parts of the titanium dioxide coating agitator that are not immersed in the cleaning agent.

[0013] Furthermore, the shape of the cleaning scraper matches the shape of the interior of the mixing vessel, with rounded edges to reduce wear on the inner wall of the mixing vessel; This involves adding a matching cleaning scraper above the liquid surface to remove residue from unsoaked areas, reducing manual intervention and further enhancing cleaning efficiency.

[0014] Furthermore, the cleaning agent includes, but is not limited to, water.

[0015] Furthermore, the inner cavity of the stirring vessel is provided with a composite structure layer, which is used to reduce the impact of noise generated during the stirring process on the outside world.

[0023] Furthermore, each of the baffle plates is provided with multiple small holes, the diameter of which is 2-5mm, so that the slurry forms more turbulence during the stirring process, further enhancing the stirring effect, allowing the titanium dioxide to fully contact the coating agent, and improving the coating quality.

[0024] Furthermore, the upper part of the mixing vessel is also provided with a titanium dioxide feed pipe.

[0025] Furthermore, the titanium dioxide feed pipe is equipped with a filter screen to prevent impurities and coarse particles from entering the mixing vessel, thus ensuring the quality of the coating process.

[0026] Furthermore, the filter screen is designed to be detachable, making it easy to replace and clean.

[0027] Furthermore, the filter screen has a mesh size of 300-500 mesh.

[0028] Furthermore, the stirring assembly includes a stirring column and a stirring blade assembly located on the stirring column and near the bottom of the stirring vessel.

[0029] Furthermore, the stirring blade assembly includes at least two stirring blades.

[0030] Furthermore, the stirring blade is a propulsion stirring blade.

[0031] Furthermore, the surface of one or both sides of the stirring blade is provided with raised textures to increase the contact area between the stirring blade and the slurry in the mixing vessel, thereby improving the stirring efficiency and making the stirring more uniform.

[0032] Furthermore, the shape of the texture includes, but is not limited to, wavy, zigzag, and striped shapes.

[0033] Furthermore, a stirring motor is provided at the upper part of the stirring vessel, and the stirring motor is connected to the stirring column to control the rotation of the stirring column.

[0034] Furthermore, the stirring column has a hollow structure with a cooling water channel inside. The two ends of the cooling water channel are respectively provided with an inlet and an outlet to cool the stirring column in time during the stirring process, so as to prevent the stirring column from heating up due to prolonged stirring, which would affect the stirring effect and service life.

[0035] Furthermore, the coating agent feeding assembly includes an acidic tube assembly and an alkaline tube assembly.

[0036] Furthermore, the acidic tube assembly includes an acidic feed tube and an acidic discharge ring tube, wherein the acidic discharge ring tube is located in a ring shape below the acidic feed tube.

[0045] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0046] It should be noted that the term "comprising" in the specification, claims, and accompanying drawings of this application is intended to cover a non-exclusive inclusion. In this application, terms indicating orientation or positional relationship, such as "above" and "below," are based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for better describing this application and its embodiments and are not intended to limit the indicated components to having a specific orientation. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0047] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] like Figure 1-3 As shown, this embodiment provides a stirrer for coating titanium dioxide, including a stirring vessel 1, a stirring assembly, a cleaning assembly, and a coating agent feeding assembly; like Figure 3 As shown, the cleaning assembly includes a connecting seat 2, a plurality of water nozzles 201 disposed on the connecting seat 2, a baffle 202 located outside the water nozzles 201, and an elastic component 203 located inside the connecting seat 2 connecting the baffle 202; the baffle 202 and the connecting seat 2 are movably connected. In this embodiment, the elastic component 203 is a spring.

[0049] During the mixing of titanium dioxide and coating agent by the agitator for titanium dioxide coating, the baffle 202, due to the tightening effect of the elastic component 203, blocks the water spray nozzle 201, preventing titanium dioxide, coating agent, or coated slurry from entering the cleaning assembly. When cleaning the agitator for titanium dioxide coating, the cleaning agent is introduced into the connecting seat 2 through the connector. The pressure in the connecting seat 2 increases, the elastic component 203 stretches, the baffle 202 moves away from the water spray nozzle 201, and the cleaning agent is sprayed from the water spray nozzle 201 into the mixing tank 1 to clean the agitator for titanium dioxide coating. That is, the agitator for titanium dioxide coating in this embodiment achieves self-cleaning and anti-clogging design by setting a dynamic water spray cleaning assembly. Specifically, the water spray nozzle 201 adopts a structure in which the elastic component 203 and the baffle 202 cooperate. It closes during mixing to prevent slurry from entering, and automatically opens hydraulically during cleaning to achieve residue-free spray cleaning. In this embodiment, a cleaning agent flow meter is provided on the connector. The higher the flow rate of the cleaning agent, the greater the pressure within the connecting seat 2, and the greater the distance between the baffle 202 and the spray nozzle 201. Conversely, the lower the flow rate of the cleaning agent, the lower the pressure within the connecting seat 2, and the smaller the distance between the baffle 202 and the spray nozzle 201. When no cleaning agent is supplied to the connecting seat 2, the baffle 202 is tightly fitted to the outside of the spray nozzle 201 due to the tightening effect of the elastic component 203. That is, the cleaning agent flow rate is linked to the opening degree of the baffle 202 (the higher the flow rate, the larger the opening degree), precisely controlling the cleaning coverage area.

[0050] like Figure 1 As shown, the connecting seat 2 is fixed on the stirring assembly and rotates with the stirring assembly.

[0051] In this embodiment, each of the spray nozzles 201 is evenly arranged on the connecting seat 2, and each spray nozzle 201 has a different angle. During the rotation of the connecting seat 2, the titanium dioxide coating agitator can be filled with cleaning agent, thus cleaning the titanium dioxide coating agitator during the stirring process. That is, by designing the spray nozzles 201 with differentiated angles, combined with the rotation of the stirring assembly, thorough cleaning of the stirring vessel 1 is achieved.

[0052] In some embodiments, the cleaning assembly further includes a cleaning scraper, which is detachably mounted on the connecting seat 2 and positioned above the liquid surface inside the titanium dioxide coating agitator. This scraper cleans the areas inside the agitator that are not immersed in the cleaning agent. Furthermore, the shape of the cleaning scraper matches the shape of the interior of the mixing vessel 1, with rounded edges to reduce wear on the inner wall of the mixing vessel 1. In other words, by adding a matching cleaning scraper above the liquid surface, residue from unimmersed areas is removed, reducing manual intervention and further enhancing cleaning efficiency.

[0053] In this embodiment, the cleaning agent is water.

[0054] like Figure 1 As shown, the inner cavity of the stirring vessel 1 is provided with a composite structure layer 101, which is used to reduce the impact of noise generated during the stirring process on the outside world.

[0055] In this embodiment, the composite structure layer 101 is provided with a sound-absorbing cotton layer, a sound-insulating felt layer and a damping material layer from the inside of the stirring vessel 1 outward.

[0056] like Figure 1 As shown, the bottom of the mixing vessel 1 is an inverted cone shape and is provided with a coating titanium dioxide slurry discharge port 102. The angle α between the side of the inverted cone and the ground is 15°, which is conducive to the discharge of coating titanium dioxide slurry after coating, reducing slurry residue and improving discharge efficiency.

[0057] like Figure 1 As shown, the outer wall of the stirring vessel 1 is also provided with a heating jacket 103, into which steam or heat transfer oil is introduced to control the temperature during the coating process and to keep the temperature warm.

[0058] In this embodiment, the temperature range controlled by the heating jacket 103 is 80-90℃.

[0059] In this embodiment, a temperature sensor is also provided on the inner wall of the stirring vessel 1 to measure the temperature inside the stirring vessel 1 in real time. It is electrically connected to the heating jacket 103 and can be adjusted in real time to ensure the stability of the coating reaction temperature.

[0060] like Figure 1-2 As shown, an auxiliary stirring device is also provided on the inner wall of the stirring vessel 1.

[0061] In this embodiment, the auxiliary stirring device includes six baffles 104 evenly arranged, and the angle β between each baffle 104 and the inner wall of the stirring vessel 1 is 10°.

[0062] In some embodiments, each of the baffles 104 is further provided with a plurality of small holes, the diameter of which ranges from 2 to 5 mm, so that the slurry forms more turbulence during the stirring process, thereby further enhancing the stirring effect, allowing the titanium dioxide to come into full contact with the coating agent, and improving the coating quality.

[0063] like Figure 1 As shown, the upper part of the mixing vessel 1 is also provided with a titanium dioxide feed pipe 105.

[0064] Furthermore, the titanium dioxide feed pipe 105 is equipped with a filter screen 106 to prevent impurities and coarse particles from entering the mixing tank 1, thus ensuring the quality of the coating process.

[0065] In this embodiment, the filter screen 106 adopts a detachable design, which is convenient for replacement and cleaning.

[0066] The filter screen has a mesh size of 500.

[0067] The stirring assembly includes a stirring column 3 and a stirring blade assembly located on the stirring column 3 and near the bottom of the stirring vessel 1.

[0068] In this embodiment, as Figure 2 As shown, the stirring blade assembly is a three-bladed propulsion stirring blade 301.

[0069] In some embodiments, the surface of one or both sides of the stirring blade 301 is provided with raised textures to increase the contact area between the stirring blade 301 and the slurry in the mixing vessel 1, enhance slurry turbulence, improve stirring efficiency, and make stirring more uniform.

[0070] In some embodiments, the shape of the texture includes, but is not limited to, wavy, zigzag, and striped patterns.

[0071] like Figure 1 As shown, a stirring motor 4 is provided at the upper part of the stirring vessel 1. The stirring motor 4 is connected to the stirring column 3 and is used to control the rotation of the stirring column 3.

[0072] In some embodiments, the stirring column 3 has a hollow structure with a cooling water channel inside. The two ends of the cooling water channel are respectively provided with an inlet and an outlet to cool the stirring column 3 in a timely manner during the stirring process, so as to prevent the stirring column 3 from getting hot due to long-term stirring, which would affect the stirring effect and service life.

[0073] like Figure 1 As shown, the coating agent feeding assembly includes an acidic tube assembly 5 and an alkaline tube assembly 6.

[0074] The acidic tube assembly 5 includes an acidic feed tube and an acidic discharge ring tube 501, wherein the acidic discharge ring tube 501 is located in a ring shape below the acidic feed tube.

[0075] The alkaline tube assembly 6 includes an alkaline feeding tube and an alkaline discharge ring tube 601, wherein the alkaline discharge ring tube 601 is located in a ring shape below the alkaline feeding tube.

[0076] Furthermore, both the acidic discharge ring pipe 501 and the alkaline discharge ring pipe 601 have acidic and alkaline discharge ports located below them. This annular design and dispersed discharge port placement prevent excessively high local concentrations and improve coating uniformity.

[0077] In this embodiment, the coating agent feeding assembly is equipped with a flow control valve to control the flow rate of feeding and / or discharging. In some embodiments, a high-precision electric regulating valve is used to precisely control the amount of coating agent added, and the error range of the added amount can be controlled within ±1%.

[0078] In this embodiment, the acidic tube group 5 is provided with a set of acidic feed pipes and a set of acidic discharge ring pipes 501; the alkaline tube group 6 is provided with a set of alkaline feed pipes and a set of alkaline discharge ring pipes 601; these are used to achieve the dispersed addition of acidic and alkaline coating agents, which is conducive to the stirring and diffusion of the coating agent and results in a good coating effect.

[0079] In some embodiments, the acidic feed pipe and / or alkaline feed pipe are further provided with a pressure sensor to monitor the feed pressure and prevent blockage or abnormal pressure during the feed process.

[0080] In this embodiment, the top of the stirring vessel 1 is also provided with an observation port to facilitate the operator to observe the situation inside the stirring vessel 1 in real time.

[0081] In this embodiment, the side wall of the stirring vessel 1 is also provided with a sampling port, and the sampling port is provided with a sampling valve to facilitate the operator to take samples and detect the coating effect in real time.

[0082] That is, the observation port and the sampling port further improve the controllability of production.
