Description

Technical Field

[0001] This utility model relates to the technical field of zinc phosphate drying equipment, specifically to an environmentally friendly drying device for producing zinc phosphate. Background Technology

[0002] Zinc phosphate is an inorganic compound composed of zinc cations and phosphate anions. Due to its non-toxicity and excellent rust-preventing and adhesive properties, it is widely used in coatings, dentistry, and many other fields. Zinc phosphate is usually produced in a paste-like form from the equipment, so an environmentally friendly drying device is required. Through heating, stirring, and other operations, a large amount of fine powder is formed, thus producing zinc phosphate in the desired state. Environmentally friendly drying devices for producing zinc phosphate include rotary flash dryers, stirred environmentally friendly dryers, hollow paddle dryers, and other equipment.

[0003] Most current zinc phosphate stirring-type environmentally friendly drying devices mainly consist of a stirring rack and heating tubes. The heating tubes are installed on the inner wall of the stirring tank. When the stirring rack is turned on, the zinc phosphate paste material is stirred in the stirring tank and fully contacts the heating tubes to achieve drying. However, this equipment is relatively simple to use, which only uses heating tubes for drying, resulting in low drying efficiency and inconvenience. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] This utility model provides a technical solution: such as Figure 1 - Figure 6 As shown in this embodiment, an environmentally friendly drying device for producing zinc phosphate includes: a drying tank 1, a feeding pipe 21 fixedly connected to the bottom of the inner wall of the drying tank 1, a spiral feeding rack 24 rotatably connected inside the feeding pipe 21, a motor 13 installed in the middle of the upper end of the drying tank 1, the output end of the motor 13 being connected to one end of the spiral feeding rack 24 via a coupling, a feed inlet 25 penetrating one side of the outer surface of the feeding pipe 21, a drying chamber 2 fixedly connected to one side of the drying tank 1, two fans 22 installed on one side of the interior of the drying chamber 2, and a heating rod 23 installed on the other side of the interior of the drying chamber 2, the heating rod 23 being located at the air outlet of the fan 22.

[0019] The zinc phosphate in the drying tank 1 is dried by heating strip 15. The motor 13 is turned on and the screw feeder 24 rotates in the feeding pipe 21. The zinc phosphate in the drying tank 1 enters the feeding pipe 21 from the inlet 25. The screw feeder 24 conveys the zinc phosphate to the top position and sprinkles the zinc phosphate around. At the same time, the fan 22 and the heating rod 23 are turned on to blow the gas heated by the heating rod 23 onto the freshly transported zinc phosphate, which performs secondary drying on the zinc phosphate in the drying tank 1, improving the drying efficiency of the equipment. The feeding pipe 21 and the screw feeder 24 work together to avoid the material in the drying tank 1 from having any drying dead corners.

[0020] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a processing box 3 is fixedly connected to the other side of the drying tank 1. A connecting pipe 31 is fixedly connected to the air outlet of the processing box 3. One end of the connecting pipe 31 is fixedly connected to the air inlet of the drying box 2. An installation port is opened through the upper side of the processing box 3. A filter plate 32 is detachably installed on the inner wall of the installation port. The filter plate 32 can be installed and fixed in the installation port by bolts or clips.

[0021] Through the structural design of the processing box 3, connecting pipe 31 and filter plate 32, when the air dried by the fan 22 and heating rod 23 enters the processing box 3, the filter plate 32 filters the zinc phosphate in the air, and the air re-enters the drying box 2 through the connecting pipe 31, realizing the drying air circulation, reducing the drying heat loss in the drying tank 1, improving the drying efficiency of the equipment, and this structural design eliminates the need to emit exhaust gas, avoiding exhaust gas emissions into the air and causing pollution, thus achieving environmental protection of the equipment.

[0022] like Figure 5 and Figure 6 As shown, an electric cylinder 33 is installed in the middle of the upper part of the processing box 3, and a scraper 34 is provided inside the processing box 3. The upper end of the scraper 34 is fixedly connected to one end of the telescopic rod of the electric cylinder 33, and a ramp 35 is fixedly connected to the bottom of the inside of the processing box 3.

[0023] By activating the electric cylinder 33, the scraper 34 slides up and down inside the processing box 3 to scrape off the zinc phosphate on the surface of the filter plate 32. The scraped zinc phosphate slides down the slope 35 into the drying tank 1 to prevent the filter holes of the filter plate 32 from becoming clogged.

[0024] like Figure 2 - Figure 4As shown, a stirring frame 14 is rotatably connected to the outer surface of the feeding pipe 21. Multiple L-shaped connecting frames 16 are fixedly connected to the upper end of the stirring frame 14. One end of each L-shaped connecting frame 16 is fixedly connected to one side of the outer surface of the spiral feeding frame 24. A heating strip 15 is embedded in the inner wall of the drying tank 1. By turning on the heating strip 15, the zinc phosphate in the drying tank 1 is heated. When the motor 13 is turned on, the spiral feeding frame 24 rotates, causing the zinc phosphate in the drying tank 1 to be stirred. The stirred zinc phosphate adheres to the heating strip 15, and the zinc phosphate is heated and dried.

[0025] like Figure 1 and Figure 2 As shown, a feed pipe 11 is fixedly connected to the other side of the upper end of the drying tank 1. A sealing cap 12 is threadedly connected to the upper end of the feed pipe 11, and the lower end of the feeding pipe 21 extends out of the drying tank 1. The feed pipe 11 is used to add zinc phosphate into the drying tank 1. The feeding pipe 21 and the feed port 25 cooperate to discharge the processed zinc phosphate. The sealing cap 12 is used to seal the feed pipe 11 to prevent some zinc phosphate from being discharged during drying, which would pollute the environment and ensure that the equipment is environmentally friendly. A valve is installed at the lower end of the feeding pipe 21.

[0026] This utility model provides an environmentally friendly drying device for producing zinc phosphate, the specific working principle of which is as follows: When drying zinc phosphate, firstly, the paste-like zinc phosphate is added into the drying tank 1 through the feed pipe 11, then the feed pipe 11 is blocked with the sealing cap 12. The heating bar 15 is turned on to heat the zinc phosphate in the drying tank 1. At the same time, the motor 13 is turned on, and the screw feeder 24 and the stirring rack 14 rotate. The zinc phosphate in the drying tank 1 enters the feed pipe 21 through the feed port 25. The screw feeder 24 transports the zinc phosphate to the top position, and the zinc phosphate is sprinkled around. The fan 22 and the heating rod 23 are turned on, and the gas heated by the heating rod 23 is blown onto the zinc phosphate that has just been transported, and the zinc phosphate in the drying tank 1 is dried a second time. When the air dried by the fan 22 and the heating rod 23 enters the processing box 3, the filter plate 32 filters the zinc phosphate in the air. The air re-enters the drying box 2 through the connecting pipe 31 to realize the drying air circulation. The above operation is repeated to achieve rapid drying of zinc phosphate.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
