Description

Technical Field

[0001] This utility model relates to an anti-splash device and an anti-splash stirring device for a sludge stirring and solidification laboratory, belonging to the field of stirrer preparation technology. Background Technology

[0002] Silt has a high water content, reaching up to 500-600%. It is usually solidified by chemical flocculation or mechanical dewatering to 50-60%. However, chemical or mechanical dewatering is expensive. Developing a solidifying agent for dredged soil with high water content can eliminate the cost of mechanical dewatering and achieve rapid solidification.

[0003] In the current laboratory mixing equipment, wet materials tend to splash out during high-speed mixing of high-moisture sludge. As the moisture content of the sludge decreases with the addition of a hardener, the viscosity of the mixed materials increases. If the material dries and clumps during mixing, it will result in uneven mixing. However, high-moisture dredged soil is prone to splashing when mixed with hardeners in the laboratory. An anti-splash mixing device can effectively avoid this problem.

[0004] To solve the above problems, there is an urgent need for a mixing device that can quickly mix wet sludge with high moisture content without splashing, and can also mix materials with high viscosity evenly without clumping, thereby improving mixing efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-splash device and an anti-splash mixing device for sludge mixing and solidification laboratory, which reduces splashing when mixing materials, improves the uniformity of mixing, and can mix evenly in any situation of material addition.

[0006] To achieve the above objectives / to solve the above technical problems, this utility model adopts the following technical solution:

[0007] In a first aspect, this utility model provides a splash-proof device, including a cover, a connector and a base;

[0008] The cover includes at least two separate covers; the at least two separate covers can be combined into a whole to cover the container opening of the stirrer;

[0009] Each of the sub-covers is connected to the base via the connector;

[0010] The contact surfaces of the sub-covers that come into contact with each other are respectively provided with splicing structures for splicing the contacting sub-covers.

[0011] The above setup achieves the following technical effects: Multiple covers, adjusted individually, can be assembled into a circular lid to cover the container opening, effectively preventing wet materials from splashing outwards during high-speed mixing. The splicing structure makes the two covers more secure when joined, preventing them from easily separating during mixing.

[0012] Furthermore, the cover includes two sub-covers, each of which is a semi-circular ring in shape;

[0013] The two parts can be combined to form a ring-shaped lid, which is used to cover the mouth of the stirrer container and is constricted in the middle.

[0014] Furthermore, the splicing structure includes magnetic pieces disposed on the contact surfaces where the individual enclosures come into contact with each other.

[0015] The technical effect achieved by the above settings is that the magnetic sheet makes the two parts of the cover more secure when spliced ​​together, and it is not easy for them to separate during the stirring process.

[0016] Furthermore, the connector is a snakeskin connecting pipe; one end of the snakeskin connecting pipe is connected to the cover body, and the other end is connected to the base.

[0017] The technical effects achieved by the above settings are as follows: the snake-skin connecting pipe has a supporting function and a certain rigidity, and can be freely adjusted and maintain its shape. One end of the snake-skin connecting pipe is connected to the cover, and the other end is connected to the base. It is used to connect the cover and the base and maintain their adjusted positional relationship when adjusting the relative positions of the cover and the base.

[0018] Furthermore, the base can be any one or more of a clamping base, a welding base, and an adhesive base.

[0019] The above setup achieves the following technical effect: the base fixes the splash-proof device to the support frame or workbench, and the type of base can be freely selected according to the actual situation.

[0020] Furthermore, the base is a clamping base, including an upper pressure plate, a lower pressure plate, and a tubular connecting nut;

[0021] Both the upper and lower pressure plates are provided with through threaded holes; both the upper and lower pressure plates engage with the tubular connecting nut through the threaded holes.

[0022] The upper pressure plate is used to connect with the connector.

[0023] The technical effect achieved by the above settings is that both the upper and lower pressure plates are fitted onto the tubular connecting nut, which enables rapid feed and locking.

[0024] Furthermore, the inner sides of the upper and lower pressure plates of the clamping base are also provided with anti-slip pads, which are anti-slip rubber pads with anti-slip patterns; the anti-slip pads are bonded to the upper and lower pressure plates.

[0025] The technical effects achieved by the above settings are: the anti-slip mat can play a role in preventing slipping and absorbing shock.

[0026] Furthermore, the base is a welded base, including a welded component and a connector for connecting with the connecting component. The welded component is used to fix the base to the support frame or the workbench surface.

[0027] The above settings achieve the following technical effects: providing support and fixation; the connector prevents the connecting parts from rotating or loosening.

[0028] Furthermore, the base is an adhesive base, the bottom of the adhesive base is flat, and the surface is provided with double-sided adhesive.

[0029] In a second aspect, the present invention provides a laboratory anti-splash mixing device for high moisture content sludge mixing and solidification, comprising a support frame, a stirrer, and an anti-splash device as described in the first aspect.

[0030] Furthermore, the stirrer includes a hollow container with an open top and a stirring paddle;

[0031] The agitator includes a moving agitator, a first stationary agitator, and a second stationary agitator.

[0032] The moving agitator includes a moving drive shaft and moving agitating scraper teeth; the moving drive shaft adopts a hollow cylindrical structure, and the moving agitator is a disc turbine agitator.

[0033] The first static stirring impeller includes a first shaft and a first scraping tooth;

[0034] The second static stirring shaft includes a second shaft and a second scraper tooth;

[0035] The second shaft is a hollow cylindrical structure, with one end connected to a support frame and the other end connected to a second scraper tooth;

[0036] One end of the drive shaft is connected to the support frame, and the other end passes through the inner hole of the second shaft and extends out. Its extended end is connected to the moving stirring scraper teeth.

[0037] One end of the first shaft is connected to a support frame, and the other end passes through the inner hole of the cylinder that passes through the drive shaft and extends out, with its extended end connected to the first scraper tooth.

[0038] The technical effect achieved by the above settings is that the scraping teeth on the static stirring paddle and the blades on the moving stirring paddle interweave, causing the material to be continuously divided and preventing the material from agglomerating during the stirring process.

[0039] The reason for setting up two static stirring paddles is that if a single static stirring paddle is used, the material in the upper or lower half of the static stirring paddle may agglomerate. However, if two static stirring paddles are used, the upper and lower parts of the moving stirring paddle can be stirred separately, which more effectively prevents the material from agglomerating.

[0040] Furthermore, both the first and second scraping teeth adopt a four-long cylindrical structure, and the angle between any two scraping teeth is ninety degrees.

[0041] Furthermore, the anti-splash stirring device also includes a drive motor and a gearbox mounted on the support frame; the output shaft of the drive motor is connected to the moving stirring paddle through the gearbox.

[0042] Furthermore, the anti-splash stirring device also includes a container rack; the container rack includes a vertical rail and a support platform slidably disposed on the vertical rail, the support platform being disposed below the stirrer and capable of supporting the container to move up and down.

[0043] The technical effects achieved by the above configuration are as follows: The main body of the foundation is an L-shaped block with a right angle and two opposing planes. At the right angle of the L-shaped block, there is a smooth curved transition, creating a smooth connection between the two planes. On the longer plane (transverse plane) of the L-shaped block of the foundation, there is a circular groove. The edge of this groove is perpendicular to the transverse plane, thus...

[0044] The container rack serves two purposes: the circular groove is used to place the mixing container, the support platform is connected to the vertical rail to support the container's up and down movement, and the support platform is fixed to a fixed position on the vertical rail by pins or rail dampers.

[0045] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0046] In this invention, the anti-splash device can minimize the amount of material flying out. The scraping teeth on the stationary stirring paddle and the blades on the moving stirring paddle intersect each other, so that the material is continuously divided, avoiding the agglomeration of material during the stirring process. Thus, it has a good stirring effect on both wet and dry materials in the solidification process of sludge with high water content. Attached Figure Description

[0057] like Figure 1 and Figure 4 As shown, this embodiment provides a splash-proof device, including a cover 5, a connector 6, and a base;

[0058] The cover 5 includes at least two separate cover bodies 5; the at least two separate cover bodies 5 can be combined into a whole for covering the container opening of the stirrer 4;

[0059] Each of the sub-covers 5 is connected to the base via a connector 6;

[0060] The contact surfaces of the sub-covers 5 that come into contact with each other are provided with splicing structures for splicing the contacting sub-covers 5.

[0061] Implementation principle: After adjusting the positions of multiple covers 5, they are assembled into a circular lid that covers the container opening, effectively preventing wet materials from splashing outwards during high-speed mixing. The splicing structure makes the two parts of the cover 5 more secure when joined, and less likely to separate during mixing. Example 2

[0062] Based on the same design principle as Embodiment 1, this embodiment provides a splash-proof device, including a cover 5, a connector 6, and a base, such as... Figure 1 As shown, the base is fixed on the support frame 1 of the stirring device or on the workbench. The cover 5 and the base are connected by a connector 6. The connector 6 has a supporting function and a certain rigidity, and can be freely adjusted and maintain its shape. The cover 5 can be freely adjusted in position and is maintained in position by the connector 6.

[0063] like Figure 4 As shown, the cover 5 includes two sub-covers 5, each of which is a semi-circular shape; the two sub-covers 5 can be combined to form a circular lid, which is used to cover the container opening of the stirrer 4 and is constricted in the middle.

[0064] The cover 5 can also be of other shapes, quantities, and sizes, as long as it can cover the container opening.

[0065] like Figure 4 As shown, specifically, the splicing structure of the two sections of the cover 5 includes magnets 51 disposed on the contact surfaces where the sections of the cover 5 come into contact with each other. The magnets 51 make the two sections of the cover 5 more secure when spliced, and less likely to separate during the stirring process.

[0066] like Figure 4 As shown, specifically, connector 6 is a snakeskin connecting pipe; one end of the snakeskin connecting pipe is connected to the cover body 5, and the other end is connected to the base. The snakeskin connecting pipe has a supporting function and a certain rigidity, and can be freely adjusted and maintain its shape. One end of the snakeskin connecting pipe is connected to the cover body 5, and the other end is connected to the base. It is used to connect the cover body 5 and the base and maintain their adjusted positional relationship when adjusting the relative positions of the cover body 5 and the base.

[0067] Specifically, the base can be any one or more of the following: clamping base 7, welding base, and adhesive base. The base fixes the splash guard to the support frame 1 or the workbench, and the type of base can be freely selected according to the actual situation.

[0068] Preferred, such as Figure 5As shown, the base is a clamping base 7, including an upper pressure plate 71, a lower pressure plate 72, and a tubular connecting nut 73. Both the upper pressure plate 71 and the lower pressure plate 72 have through threaded holes. Both the upper pressure plate 71 and the lower pressure plate 72 engage with the tubular connecting nut 73 through the threaded holes. The upper pressure plate 71 is used to connect with the connector 6. The upper pressure plate 71 and the lower pressure plate 72 are both fitted onto the tubular connecting nut 73, enabling rapid feed locking.

[0069] Preferably, the inner sides of the upper pressure plate 71 and the lower pressure plate 72 of the clamping base 7 are also provided with anti-slip pads 74. The anti-slip pads 74 are anti-slip rubber pads with anti-slip textures. The anti-slip pads 74 are bonded to the upper pressure plate 71 and the lower pressure plate 72. The anti-slip pads 74 can play a role in anti-slip and shock absorption.

[0070] Preferred, such as Figure 6 As shown, the base is a welded base, including a welded component 81 and a connector 82 for connecting with the connector 6. The welded component 81 is used to fix the connection to the support frame 1 or the workbench surface, providing support and fixation; the connector 82 prevents the connector 6 from rotating or loosening.

[0071] Preferred, such as Figure 7 As shown, the base is an adhesive base. The bottom of the base 91 is flat, and double-sided adhesive 92 is provided on the surface.

[0072] You can choose any one of the three bases or use them in combination, as long as they can provide a secure hold. Example 3

[0073] like Figure 1 As shown, this embodiment provides a high-moisture-content sludge mixing and solidification laboratory anti-splash mixing device, which includes the anti-splash device as in Embodiment 2, and also includes a support frame 1, a container frame 3, a gearbox 2, and a stirrer 4. The stirrer 4 includes a moving stirring paddle 41, a first static stirring paddle 42, and a second static stirring paddle 43.

[0074] like Figure 2 As shown, the mixer 4 includes a hollow container with an open top and a stirring paddle;

[0075] like Figure 3 As shown, the stirring paddle includes a moving stirring paddle 41, a first stationary stirring paddle 42, and a second stationary stirring paddle 43.

[0076] The moving agitator 41 includes a moving drive shaft 44 and moving agitating scraper teeth; the moving drive shaft 44 adopts a hollow cylindrical structure, and the moving agitator 41 is a disc turbine agitator.

[0077] The first static stirring impeller 42 includes a first shaft and a first scraping tooth;

[0078] The second static stirring shaft includes a second shaft and a second scraper tooth;

[0079] The second shaft is a hollow cylindrical structure, with one end connected to the support frame 1 and the other end connected to the second scraper tooth;

[0080] One end of the drive shaft 44 is connected to the support frame 1, and the other end passes through the inner hole of the second shaft and extends out. Its extended end is connected to the moving stirring scraper teeth.

[0081] One end of the first shaft is connected to the support frame 1, and the other end passes through the inner hole of the cylinder through the drive shaft 44 and extends out, with its extended end connected to the first scraper tooth. The scraper tooth on the stationary stirring paddle and the blades on the moving stirring paddle 41 interweave, causing the material to be continuously divided and preventing the material from agglomerating during the stirring process.

[0082] The reason for setting two static stirring paddles is that if a single static stirring paddle is used, the material in the upper or lower half of the static stirring paddle may agglomerate. However, if two static stirring paddles are used, the upper and lower parts of the moving stirring paddle 41 can be stirred separately, which can more effectively prevent the material from agglomerating.

[0083] Specifically, such as Figure 3 As shown, both the first and second scraping teeth adopt a structure of four long cylindrical bodies, and the angle between any two scraping teeth is ninety degrees.

[0084] like Figure 1 and Figure 2 As shown, the anti-splash stirring device also includes a drive motor and a gearbox 2 mounted on the support frame 1; the output shaft of the drive motor is connected to the moving stirring paddle 41 through the gearbox 2.

[0085] Specifically, the container rack 3 includes a vertical rail and a support platform that is slidably mounted on the vertical rail. The support platform is located below the stirrer 4 and can support the container to move up and down.

[0086] Specifically, the main body of the support is an L-shaped block with a right angle and two opposing planes. At the right angle of the L-shaped block, there is a smooth curved transition, creating a smooth connection between the two planes. On the longer plane (transverse plane) of the L-shaped block, there is a circular groove. The edge of this groove is perpendicular to the transverse plane, thus securing the container. In experiments with high stirring rates, it is advisable to integrate the container and the support.

[0087] The function of container rack 3 is that the circular groove is used to place the mixing container, the support is connected to the vertical rail to support the container to move up and down, and the support is fixed to a fixed position on the vertical rail by pins or rail dampers.

[0088] To better understand the technical solution of this utility model, the following provides a method for using a laboratory anti-splash stirring device for high moisture content sludge mixing and solidification, including the following steps:

[0089] 1. The base for installing the anti-splash device can be installed on the support frame 1 of the mixing device or on the workbench surface.

[0090] 2. Remove the container from the container rack 3, add material to the container, and after adding the material, put the container back on the container rack 3 and raise the container rack 3 to an appropriate position so that the moving stirring paddle 41, the first stationary stirring paddle 42 and the second stationary stirring paddle 43 are located inside the container, and the bottom of the first stationary stirring paddle 42 is a certain distance from the bottom of the container.

[0091] 3. Adjust the position of the anti-splash device cover 5 so that the two parts of the cover 5 are combined into a ring covering the container opening. The magnets 51 on the contact surfaces of the two covers 5 attract each other, preventing the two parts of the cover 5 from separating during the stirring process. The anti-splash device can effectively prevent wet materials from flying out of the container during high-speed stirring.

[0092] 4. Turn on the drive device (such as a stirring motor), and adjust the speed of the moving stirring paddle 41 through the gearbox 2. With the cooperation of the moving stirring paddle 41 and the stationary stirring paddle, the materials are fully mixed.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0094] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
