Description

Technical Field

[0001] This utility model relates to the field of stirring technology, and in particular to a glass-lined stirrer. Background Technology

[0002] In industries such as chemical, pharmaceutical, and food, glass-lined agitators are widely used in the mixing and reaction processes of various materials due to their excellent corrosion resistance. The feed pipe, as the channel through which materials enter the agitator, directly affects the continuity of production and product quality.

[0003] In the chemical industry, many production processes involve the handling of highly corrosive materials. Although traditional glass-lined feed pipes have a certain degree of corrosion resistance, long-term contact with these highly corrosive materials will gradually erode the glass lining on their surface. Once the glass lining is damaged, the internal metal substrate will be directly exposed to the corrosive medium, and the corrosion rate of the metal will be significantly accelerated, leading to serious problems such as perforation and leakage in the feed pipe. This will not only waste materials and interrupt normal production processes, but may also cause safety accidents, threatening the personal safety of operators, and polluting the surrounding environment. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a glass-lined agitator that can solve the problem that, despite long-term contact with these highly corrosive materials, the glass-lined layer on its surface will still be gradually eroded. Once the glass-lined layer is damaged, the internal metal matrix will be directly exposed to the corrosive medium, and the corrosion rate of the metal will be significantly accelerated, leading to serious problems such as perforation and leakage in the feed pipe. This will not only cause waste of materials and interrupt the normal production process, but may also cause safety accidents, threatening the personal safety of operators, and causing pollution to the surrounding environment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a glass-lined stirrer, comprising a stirring tank, a control panel, a cover plate and a feed pipe, wherein a protective bushing assembly is provided on the feed pipe; The protective bushing assembly includes a protective bushing, two protrusions, and two positioning elements.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] Example 1: Reference Figure 1-4 A typical example of basic protection for conventional material feeding (T-shaped positioning slider + ordinary protective bushing) This embodiment is applicable to the feed protection of conventional materials (such as white sugar and flour) with particle diameter ≤5mm. By combining a T-shaped positioning slider with a common protective bushing, wear-resistant protection of the inner wall of the feed pipe is achieved, meeting the needs of daily mixing operations. Structural fit and protective effect: The positioning component 8 adopts a T-shaped positioning slider (Q235 steel material, galvanized surface treatment), which slides with the positioning groove 9 (gap ≤ 0.3mm) to ensure the precise positioning of the protective bushing 6. The protective bushing 6 is made of high-density polyethylene (HDPE) material, with a thickness of 5mm, a hardness of 60 Shore D, and a wear resistance coefficient of 0.15 (wear loss ≤ 10mg / 1000 times). The protrusion 12 and the groove 13 slide guide each other. The tightening torque of the fixing bolt 7 is 10N・m, so that the protective bushing and the feed pipe 4 form a rigid connection. When feeding conventional materials, the HDPE protective bushing can effectively buffer the impact of particles and reduce wear on the inner wall of the feed pipe. After 300 uses, the enamel layer of the feed pipe showed no obvious scratches. When disassembling, unscrew the fixing bolts and pull out the protective bushing along the positioning groove (time ≤ 1 minute). Maintenance is convenient and it is suitable for the protection of conventional material feeds in the food and chemical industries. Application results: The lifespan of the enamel layer on the feed pipe is extended from 1 year to 3 years, the replacement cost of the protective bushing is reduced by 50%, and the protection requirements under normal working conditions are met. Example 2: Reference Figure 5 Example of wear-resistant protection for high-hardness particle feed (magnetic positioning slider + tungsten carbide protective bushing) This embodiment is designed for feeding high-hardness materials (Mohs hardness ≥ 6) such as quartz sand and metal particles. It improves wear resistance by using a magnetic positioning slider and a tungsten carbide protective bushing. Wear-resistant structural reinforcement: Positioning component 8 is replaced with magnetic positioning slider 16 (neodymium iron boron magnet, adsorption force ≥30N), which forms a pre-fixed connection with the magnetic seat in the positioning groove 9 to prevent bushing displacement caused by impact from high-hardness particles. The protective bushing 6 is replaced with tungsten carbide alloy (WC-Co, hardness HV1500), with a wear-resistant layer (thickness 0.5mm) laser-coated on the surface, reducing the wear resistance coefficient to 0.05 (wear loss ≤2mg / 1000 times). The protrusion 12 and the groove 13 are interference-fitted (tolerance H7 / p6) to enhance impact resistance stability. When feeding high-hardness particles, the tungsten carbide protective bushing can withstand the impact of high-speed particles (flow velocity ≥ 5m / s). After 1000 uses, the wear of the bushing is ≤ 0.1mm, and the enamel layer of the feed pipe remains intact. When disassembling, the magnetic suction seat must be demagnetized first, and then the fixing bolts must be removed. Although the steps are increased, the protection effect is improved by 300%. It is suitable for feeding high-hardness materials in the mining and ceramic industries. Effects in high-wear scenarios: Reduces the frequency of feed pipe maintenance, extends the continuous operation time of the equipment from 8 hours to 72 hours, and reduces downtime losses.

[0022] Furthermore, during use, the material enters the mixing tank 1 through the feed pipe 4. Because a protective bushing assembly 6 is installed inside the feed pipe 4, the protective bushing 6 effectively isolates the material from direct contact with the inner wall of the feed pipe 4. For corrosive materials, the corrosion-resistant material of the protective bushing 6 prevents the feed pipe 4 from being corroded. For materials containing solid particles, the wear-resistant properties of the protective bushing 6 prevent wear on the inner wall of the feed pipe 4. During the material entry process, the positioning component 8 (T-shaped positioning slider or magnetic positioning slider 16) cooperates with the positioning groove 9 on the feed pipe 4 to ensure that the protective bushing 6 does not shift under the impact of the material, thus stably performing its protective function. After the material enters the mixing tank 1, the operator starts the motor 5 through the control panel 2. The motor 5 is powered on and its output drives the stirring shaft 11 to rotate. The stirring blades on the stirring shaft 11 stir the material. The rotation of the stirring blades causes the material to flow axially and radially, achieving thorough mixing. During the stirring process, the operator can adjust the speed of the motor 5 through the control panel 2 according to the properties of the material and process requirements. To achieve the best mixing effect, the stirring intensity is controlled. If heating is required during the mixing process, the operator can activate the heating tubes 10 via the control panel 2. The spirally arranged heating tubes 10 begin to work, heating the material in the mixing tank 1. The heating tubes 10 are evenly distributed inside the mixing tank 1, ensuring uniform heating of the material and preventing local overheating or undercooling. Simultaneously, the control panel 2 can monitor and adjust the heating temperature in real time to ensure that the material reacts or mixes within the set temperature range, meeting the strict temperature requirements of different processes. After the material is stirred and reacted, the valve on the discharge pipe 15 is opened, and the material in the mixing tank 1 is discharged through the discharge pipe 15 under gravity, entering the subsequent production stage. After discharge, if the protective bushing 6 needs to be replaced or maintained, for the magnetic positioning slider 16, the reversibility of the magnetic force can be used to easily disassemble it. For the T-shaped positioning slider, the fixing bolts 7 can be unscrewed to remove the protective bushing 6 from the feed pipe 4 for replacement or cleaning, which is convenient and quick, ensuring the continuous and stable operation of the equipment.

[0023] By using polytetrafluoroethylene (PTFE) material for the protective bushing assembly, the protective bushing 6 can effectively isolate the material from the metal substrate of the feed pipe 4 when handling highly corrosive materials such as sulfuric acid and hydrochloric acid in the chemical industry. This avoids the problem of rapid metal corrosion caused by the erosion of the enamel layer in traditional feed pipes. Even when conveying materials containing solid particles, the wear-resistant properties of the protective bushing 6 can prevent wear on the inner wall of the feed pipe 4, greatly extending the service life of the feed pipe 4 and reducing material waste and equipment replacement costs caused by pipe corrosion, perforation, and leakage.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
