DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0032] In general, the integrated device of the present invention includes a solid-liquid mixing component, a filtering component, and a powder-making component. The solid-liquid mixing component is used to evenly mix solid materials and liquids. The filtering component connects the solid-liquid mixing component and the powder-making component via a pipeline, filtering out solid impurities from the solid-liquid mixture in the solid-liquid mixing component and extracting the powder-liquid mixture to the powder-making component, which extracts solid powder from the powder-liquid mixture.

[0033] Because the present invention integrates the solid-liquid mixing component and the powder-making component into an integrated device, the solid-liquid mixing component can also serve as a reaction vessel. Furthermore, the present invention preferably provides user-operated elements, such as buttons or knobs, for each component. Thus, the complex process of reacting the solid and liquid raw materials and then extracting the solid powder can be conveniently and easily achieved through the present invention, greatly improving the efficiency of powder preparation.

[0034] As previously mentioned, the solid-liquid mixing assembly is used to uniformly mix solid materials and liquids. However, it should be noted that in actual powder production processes, the solid materials and liquids often undergo a chemical reaction to produce powder. Therefore, the solid-liquid mixing assembly is also suitable as a container for chemical reactions. For example, when preparing flocculant powder, acid or alkaline leaching processes are often required. In these cases, the solid-liquid mixing assembly may also be referred to as an acid or alkaline leaching assembly.

[0035] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0036] Figure 1 This is a schematic structural diagram of an integrated device for preparing modified fly ash according to an embodiment of the present invention. Figure 1 As shown, the integrated device for powder preparation provided in this embodiment is used to prepare modified fly ash as a flocculant.

[0037] Specifically, the apparatus includes an acid leaching assembly, a filtration assembly, and a powder making assembly. The acid leaching assembly is a specific implementation of the solid-liquid mixing assembly of this embodiment. It should be understood that, depending on the different solid-liquid mixing raw materials and the different chemical reactions occurring, the solid-liquid mixing assembly can also be implemented as a mixing vessel for different chemical reactions.

[0038] like Figure 1 As shown, in this embodiment, the acid leaching assembly includes a stirring rod 1, an acid leaching tank serving as a mixing tank 2, a first heating plate 3-1, a first control console 4-1, and a first bracket 12-1. The acid leaching tank is a specific embodiment of the mixing tank 2 in this embodiment.

[0039] The first control console 4-1 serves as the base and control center of the pickling assembly. Its upper surface is a flat surface, and its side is provided with a first speed control knob 5-1 and a first temperature control knob 6-1.

[0040] The first heating plate 3-1 is placed on the upper surface of the first console 4-1, and the control circuit of the first heating plate 3-1 is electrically connected to the control end of the first temperature control knob 6-1 of the first console 4-1, so that the user can control the heating power of the first heating plate 3-1 by turning the first temperature control knob 6-1, thereby controlling the heating temperature.

[0041] First heating plate 3-1 is flat, allowing the acid leaching tank to be placed on its upper surface. In this embodiment, the acid leaching tank is used to acid-leach fly ash. When the present invention is used to prepare other powders, mixing tank 2 can also serve as a general mixing container rather than an acid leaching tank.

[0042] To promote uniform reaction of materials during the pickling process, a stirring rod 1 is provided above the pickling tank 2 of the present invention. The stirring rod 1 is suspended within the storage space of the pickling tank 2 and is held by a first bracket 12-1. The stirring rod 1 is used to stir the solid-liquid mixture in the pickling tank 2. The first bracket 12-1 can be fixed to the side or top of the first control console 4-1, or to the ground or other base, but is preferably integrated with the first control console 4-1.

[0043] Furthermore, the control circuit of the stirring rod 1 is electrically connected to the control end of the first speed control knob 5-1 of the first console 4-1, so that the user can control the rotation rate of the stirring rod 1 by turning the first speed control knob 5-1, thereby controlling the speed of stirring.

[0044] The bottom end of the acid leaching tank 2 is equipped with a suction port 7 for extracting the material in the acid leaching tank 2. The interior of the suction port 7 or one end near the acid leaching tank 2 is equipped with a filter material 21 for filtering the extracted material. The suction port 7 is also provided with an on / off valve 13 to control the opening and closing of the suction port 7.

[0045] A thermometer 19 and a pH meter 20 are also hung in the acid leaching tank 2 to measure the temperature and pH value of the acid leaching process in the acid leaching tank 2 respectively.

[0046] The filtration assembly includes a vacuum filtration pump 8, a filtration water inlet pipe 14, and a filtration water outlet pipe 15. One end of the filtration water inlet pipe 14 is connected to the filtration port 7 of the acid leaching tank 2 and the other end is connected to the inlet of the vacuum filtration pump 8; one end of the filtration water outlet pipe 15 is connected to the outlet of the vacuum filtration pump 8 and the other end is connected to the powder making assembly.

[0047] The powder making assembly includes a purifier 9, an evaporating dish 10, a second heating plate 3-2, a second control console 4-2, a sprayer 16 and a second bracket 12-2.

[0048] The second control console 4-2 serves as the base and control center of the powder making assembly. Its upper surface is also a flat surface, and the side is provided with a second speed control knob 5-2 and a second temperature control knob 6-2.

[0049] The second heating plate 3-2 is placed on the upper surface of the second console 4-2, and the control circuit of the second heating plate 3-2 is electrically connected to the control end of the second temperature control knob 6-2 of the second console 4-2, so that the user can control the heating power of the second heating plate 3-2 by turning the second temperature control knob 6-2, thereby controlling the heating temperature.

[0050] The second heating plate 3 - 2 is also in the shape of a flat plate, so that the evaporating dish 10 can be placed on the upper surface of the second heating plate 3 - 2 .

[0051] In this embodiment, the evaporating dish 10 is a container for evaporating materials, and the evaporating dish 10 includes an evaporation area and a collection area. The second heating plate 3-2 is arranged at the bottom of the evaporating dish 10 relative to the evaporation area. Figure 1 As shown, most of the area on the right side of the evaporating dish 10 is the evaporation area, and a small area on the left side is the collection area.

[0052] The sprayer 16 is connected to the filtration assembly's filtration outlet pipe 15 and is used to evenly spray the powder-liquid mixture from the filtration assembly onto the evaporation area of ​​the evaporating dish 10. In this embodiment, the sprayer 16 is located directly above the evaporation area so that the powder-liquid mixture it sprays lands there. The evaporation area receives the powder-liquid mixture sprayed from the sprayer 16 and allows it to evaporate naturally or when heated by the second heating plate 3-2. The collection area, in contrast, is located away from the area directly below the sprayer 16.

[0053] Purifier 9 is used to absorb and purify the gas or the impurity that produces above the evaporating dish 10.In this embodiment, purifier 9 is an acid mist purifier, and it has absorption acid mist and acid-base neutralization treatment effect, and purifies the back gas discharge, and its inside is equipped with the fan that is used to suction.And the control circuit of the fan of purifier 9 is electrically connected to the control end of the second speed control knob 5-2 of the second control console 4-2, so that the user can control the rotation speed of fan by rotating the second speed control knob 5-2, thereby the speed of control fan suction.Purifier 9 is remained on the top of the evaporating dish by the second support 12-2.The second support can be fixed on the side or the top of the second control console 4-2, also can be fixed on the ground or on other pedestals, but is preferably formed as integrated structure with the second control console 4-2.

[0054] Figure 2 It is a top schematic diagram of an embodiment of the evaporating dish of the present invention. Figure 3 The evaporating dish Figure 2 The cross-sectional diagram of the cross-section A-A'. Figure 2 and Figure 3 As shown, the evaporating dish 10 of this embodiment is a circular container with a rotatable scraper 11 installed around its center. The scraper 11 is driven by a scraper motor 23 at the bottom of the evaporating dish 10 to scrape the evaporated and dried powder in the evaporation area of ​​the evaporating dish 10.

[0055] like Figure 3As shown, the bottom of the collection area of ​​the evaporating dish 10 has a powder outlet 18. The powder outlet 18 has a movable plate 17, which is hinged to the side edge of the bottom surface of the evaporating dish 10 via a hinge 22. The hinge is driven by a movable plate drive motor 27 through a transmission assembly (e.g., a worm and worm gear combination). When the scraper 11 rotates to scrape, driven by the scraper motor 23, the movable plate 17 is also driven to rotate downward about the hinge 22, thereby opening the powder outlet 18 at the bottom of the evaporating dish 10. The resulting powder leaks from the powder outlet 18 into the powder storage cup 24 below the powder outlet 18 (see Figure 1 The user can then collect the powder through the powder outlet 18 .

[0056] like Figure 1 As shown, in this embodiment, a switch 25 and a timing control button 26 are further provided on the side of the second console 4-2, and a control panel 28 ( Figure 2 、 Figure 3 not shown).

[0057] Figure 4 Schematic diagram of the control circuit of the second console 4-2. Figure 4 As shown, switch 25 is used to activate and deactivate the control panel 28 of the milling assembly. This panel integrates a controller for controlling the circuitry and serves as the master control module for the power supply and functions of each of the milling assembly's components. When the milling assembly is activated, the vacuum pump 8, purifier 9, second heating plate 3-2, scraper motor 23, and movable plate drive motor 27 are controlled by controller 28. The controller controls these functions according to a predetermined control logic.

[0058] A timing control button 26 is also connected to the controller and can be read by the controller to enable the controller to control the time accordingly. For example, the controller controls the spraying time of the sprinkler and the evaporation time after spraying according to the currently set values. Thus, the timing control button 26 allows the user to set the spraying time of the sprinkler and the evaporation time after spraying according to different needs.

[0059] For example, in this embodiment, the timing control button 26 can be set to an integer of 0s to 9s. Figure 1 As shown in , the spraying time is 6s, and the evaporation time after spraying is 9s. The timing control button 26 is a conventional device, and other timing control buttons of different specifications with longer setting durations can also be used.

[0060] When operating the integrated powder preparation device of the present invention, the user first controls the acid leaching assembly. During operation, the user adds the material to be acid-leached to the acid leaching tank 2, then adds acid (e.g., hydrochloric acid and / or sulfuric acid). The user then turns the first speed control knob 5-1 on the first control console 4-1 to control the stirrer 1 to stir the material. Simultaneously, the user can read the pH value using a pH meter 20 to control the amount of acid added. The user then turns the first temperature control knob 6-1 to activate the heating plate 3 to heat the material in the acid leaching tank 2, while simultaneously controlling the material temperature by reading from the thermometer 19. After the reaction time is set, the next step, filtration, is ready.

[0061] Next, the user controls the filtering component to work. The user first opens the switch valve 13 on the filtration port 7. The vacuum filtration pump 8 extracts the material from the filtration port 7 of the acid leaching tank 2 through the filtration water inlet pipe 14 and filters out large particles. The filtered material passes through the filtration water outlet pipe 15 and enters the sprayer 16 of the powder making component, ready for the next powder making operation.

[0062] After the filtered material is sprayed on the evaporation area of ​​the evaporating dish 10 for a predetermined time, and then heated and dried for a certain period of time, the scraper 11 is activated to scrape the powder to the collection area of ​​the evaporating dish 10. Since the movable plate 17 is rotated open, the user can collect the powder through the powder outlet 18.

[0063] It should be noted that the sprayer 16 is located directly above the evaporating dish 10 to evenly spray the filtered material into the evaporating dish.

[0064] Preferably, the stirring rod 1, acid leaching tank 2, suction port 7, evaporating dish 10, scraper 11, first bracket 12-1, second bracket 12-2, switch valve 13 and sprayer 16 of the present invention are all made of acid and alkali resistant polytetrafluoroethylene material.

[0065] The suction filtration water inlet pipe 14 and the suction filtration water outlet pipe 15 are made of acid-resistant, alkali-resistant and high-pressure resistant rubber hoses.

[0066] It can be seen from the above embodiments that the integrated device for powder preparation of the present invention is an integrated continuous production device, which has both experimental and detection functions, is easy to operate, and is suitable for batch preparation.

[0067] In summary, the device of the present invention has a simple structure and can prepare powder continuously and in an integrated manner, eliminating the need for intermediate user operations and improving the efficiency of preparing powders such as powder flocculants. The present invention is highly suitable for laboratory operation and also for batch production.

[0068] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
