TECHNICAL FIELD

[0001] The application relates to the technical field of hazardous waste sludge treatment, in particular to a hazardous waste sludge treatment mixer. BACKGROUND

[0002] Hazardous waste sludge refers to sludge containing harmful substances generated in the process of industrial production, urban sewage treatment and the like. The sludge has certain toxicity and harmfulness, and usually needs to be specially treated to prevent the impact on the environment and human health.

[0003] In order to prevent some harmful components in the hazardous waste sludge from being too concentrated and ensure uniform distribution of various components, a mixer is usually used to treat and mix the hazardous waste sludge.

[0004] According to the search, for example, a patent with the publication number CN217042433U specifically discloses a hazardous waste sludge treatment device. The device utilizes a mixing mechanism and a feeding mechanism to realize uniform mixing of sludge and auxiliary materials and improve mixing efficiency.

[0005] However, during the treatment and mixing of hazardous waste sludge, the high water content in the hazardous waste sludge increases the flowability of the sludge, and the organic matter concentration in the sludge is reduced, resulting in uneven mixing process and reduced mixing effect. Therefore, it is necessary to provide a hazardous waste sludge treatment mixer to solve the above problems.

[0006] It should be noted that the above information disclosed in the background section of the present application is only used to understand the background technology of the concept of the present application, and therefore, it can contain information that does not constitute prior art. SUMMARY

[0031] 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.

[0032] 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.

[0033] like Figure 1 As shown, this application provides a hazardous waste sludge treatment mixer, including a support 1, a protective box 11 fixedly installed on the upper end of the support 1, a filter mechanism 2 provided on the upper end of the protective box 11, the filter mechanism 2 is used to filter hazardous waste sludge, the filter mechanism 2 has a screen hopper 21 inclinedly arranged on the upper end of the protective box 11, and a filter plate 23 fixedly installed on the bottom end of the screen hopper 21, the sludge entering the screen hopper 21 is filtered through the filter plate 23;

[0034] In order to fix the screen bucket 21, spring buffers 22 are fixedly installed on the lower ends of both sides of the screen bucket 21. The lower ends of the spring buffers 22 are fixed to the upper end of the protective box 11. The feed hopper 24 is fixedly installed at the high end of the screen bucket 21 at an outward tilt. Hazardous waste sludge can be easily added into the screen bucket 21 through the feed hopper 24.

[0035] Meanwhile, a fixed frame 4 is fixedly installed between the upper ends of the screen bucket 21, and a vibration motor 41 is fixedly installed on the fixed frame 4. Therefore, when the vibration motor 41 is started, the screen bucket 21 and the filter plate 23 can be driven to vibrate as a whole, thereby accelerating the sewage filtration speed on the filter plate 23.

[0036] like Figures 2-3 As shown, in order to mix the filtered sludge, the lowest end of the screen hopper 21 is provided with a discharge port 25, and a spiral mixer 3 is provided below the discharge port 25. The spiral mixer 3 is fixedly installed on the upper end of the protective box 11. A discharge pipe 31 is connected to the lower end of one side of the spiral mixer 3. Therefore, the filtered sludge will enter the spiral mixer 3 through the discharge port 25 for mixing, and the mixed sludge will be discharged outward through the discharge pipe 31.

[0037] In this application, the upper end of the spiral mixer 3 is provided with a guard plate 32. The guard plate 32 is wrapped around the screen hopper 21 and fitted above the spiral mixer 3, thereby preventing sludge from splashing everywhere when it enters the spiral mixer 3 from the discharge port 25.

[0038] Furthermore, the lower end of the protective box 11 is provided with a collection hopper 12, which is used to collect the filtered wastewater. A drain pipe 121 is provided on the side of the collection hopper 12 near the upper end. Therefore, the wastewater entering the collection hopper 12 will first settle, so that the fine sludge impurities will settle at the bottom of the collection hopper 12. When the liquid level of the wastewater reaches the drain pipe 121, the wastewater will be discharged through the drain pipe 121.

[0039] In order to clean and discharge the settled sludge and impurities, fixing strips 122 are fixedly installed on both sides of the upper end of the collection hopper 12, and mating plate grooves 111 are fixedly installed on both sides of the lower end of the protective box 11. The mating plate grooves 111 and the fixing strips 122 slide against each other. It can be understood that when the collection hopper 12 is installed, the fixing strips 122 are stuck in the mating plate grooves 111, which will make the collection hopper 12 fit tightly against the bottom of the protective box 11, so that the waste liquid will not splash out of the collection hopper 12 when it falls.

[0040] A handle 123 is also fixedly installed on the side of the collection hopper 12 near the sewage pipe 121. Therefore, when disassembling the collection hopper 12, the entire collection hopper 12 can be easily removed by using the handle 123, and then the sludge and impurities inside the collection hopper 12 can be cleaned.

[0041] In summary: When treating hazardous waste sludge, the hazardous waste sludge to be treated is first added to the screen hopper 21 through the feed hopper 24. Then, the vibration motor 41 is started, which drives the screen hopper 21 and the filter plate 23 to shake. At this time, the sludge slides down with the tilt and shaking of the filter plate 23. At the same time, the wastewater in the sludge will be filtered through the filter plate 23 and fall down into the collection hopper 12 for sedimentation.

[0042] After filtration, the sludge enters the spiral mixer 3 through the discharge port 25 for mixing, and then is discharged through the discharge pipe 31 for easy access to the next step. When the wastewater in the collection hopper 12 reaches a certain height, it will be discharged outward through the sewage pipe 121. Thus, the water in the hazardous waste sludge is filtered out to prevent the subsequent mixed hazardous waste sludge from becoming too fluid, and to ensure the concentration of organic matter in the sludge, making the mixing process more uniform and improving the mixing effect.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
