The following describes each embodiment of the present utility model in detail with reference to the drawings.

[0022] Embodiment 1

[0023] Please refer to Figures 1 to 4, the present utility model preferably provides a technical solution: a splash-proof hazardous waste solid-liquid separation device, including a filter cylinder 1, and a solid-liquid separation cylinder 11 installed on the inner bottom wall of the filter cylinder 1 of the scraping assembly 2; a feed pipe 12, the feed pipe 12 of the scraping assembly 2 is installed on the side wall of the filter cylinder 1 of the scraping assembly 2, and the feed pipe 12 of the scraping assembly 2 is in internal communication with the inside of the filter cylinder 1 of the scraping assembly 2; a discharge pipe 13, the discharge pipe 13 of the scraping assembly 2 is installed on the bottom surface of the filter cylinder 1 of the scraping assembly 2, and the discharge pipe 13 of the scraping assembly 2 is in internal communication with the inside of the filter cylinder 1 of the scraping assembly 2; a scraping assembly 2, the scraping assembly 2 is installed inside the filter cylinder 1 for scraping solid particles on the surface of the solid-liquid separation cylinder 11 of the scraping assembly 2; the scraping assembly 2 includes a motor 21 fixedly arranged on the upper surface of the filter cylinder 1 of the scraping assembly 2, and the output shaft of the motor 21 of the scraping assembly 2 penetrates through the filter cylinder 1 of the scraping assembly 2 and extends into the filter cylinder 1 of the scraping assembly 2; it further includes a connecting frame 22 fixedly arranged at the end of the output shaft of the motor 21 of the scraping assembly 2 and a plurality of scrapers 23 fixedly arranged on the bottom surface of the connecting frame 22 of the scraping assembly 2, and the plurality of scrapers 23 of the scraping assembly 2 are all in contact with the outer wall of the solid-liquid separation cylinder 11 of the scraping assembly 2.

[0024] In this embodiment, the scraping assembly 2 is installed inside the filter cylinder 1 for scraping solid impurities on the outer wall of the solid-liquid separation cylinder 11, such as Figure 4 shown, the motor 21 drives the connecting frame 22 to rotate, the connecting frame 22 drives the plurality of scrapers 23 to rotate, so that the scrapers 23 scrape the impurities attached to the outer wall of the solid-liquid separation cylinder 11, making them fall on the inner bottom wall of the filter cylinder 1. During this process, the scraping assembly 2 can achieve solid-liquid separation without high-speed rotation when scraping solid particles, reducing the probability of the device body shaking during operation.

[0025] Specifically, during solid-liquid separation, the staff introduces the raw material into the filter cylinder 1 through the feed pipe 12. Subsequently, the solid-liquid separation cylinder 11 retains the solid particles on the outer wall of the solid-liquid separation cylinder 11, and the liquid flows into the solid-liquid separation cylinder 11 and is discharged through the discharge pipe 13. After the liquid is discharged, the staff starts the motor 21, thereby causing the output shaft of the motor 21 to rotate, so that the connecting frame 22 and the scraper 23 rotate under the action of the output shaft of the motor 21. At this time, the scraper 23 scrapes the solid particles on the surface of the solid-liquid separation cylinder 11 to make them fall onto the inner bottom wall of the filter cylinder 1, and the solid-liquid separation can be completed.

[0026] It is worth noting that: when installing the filter cylinder 1, the staff fixes the support legs on the bottom surface of the filter cylinder 1 to the ground through bolts. Specifically, the staff drills holes in the ground. Subsequently, the staff aligns the holes opened on the support legs with the holes opened on the ground. At this time, the staff installs the bolts, and the support legs can be fixed to the ground, further reducing the probability of the device body shaking during operation.

[0027] In this utility model, solid particles on the outer wall of the solid-liquid separation cylinder 11 are scraped off by a scraping device to achieve solid-liquid separation. During the scraping process, the rotation speed of the motor 21 is relatively low, thereby reducing the probability of violent shaking of the main body of the device during the separation process.

[0028] Furthermore, a sewage discharge port 3 is formed through the bottom surface of the filter cylinder 1, and a sewage discharge pipe 4 is installed in the sewage discharge port 3; cleaning brushes 41 are fixedly arranged on the bottom surfaces of multiple scrapers 23, and the multiple cleaning brushes 41 are all in contact with the inner bottom wall of the filter cylinder 1.

[0029] Combined with Figure 4 As shown, during the rotation of the motor 21, the scraper 23 rotates along with the motor 21. Since the cleaning brush 41 is fixedly connected to the scraper 23, the cleaning brush 41 rotates along with the scraper 23, so that the cleaning brush 41 sweeps the solid particles falling on the inner bottom wall of the filter cylinder 1. When passing through the sewage discharge port 3, the solid particles fall into the sewage discharge port 3. Subsequently, they are discharged outside the filter cylinder 1 through the sewage discharge pipe 4, thereby reducing the difficulty for the staff to clean the solid particles.

[0030] Furthermore, a baffle 5 is fixedly arranged on the inner bottom wall of the filter cylinder 1, and one side side wall of the baffle 5 is flush with the inner wall of the sewage discharge port 3.

[0031] As Figure 2 、 3 shown, when the cleaning brush 41 abuts against the baffle 5, the baffle 5 blocks the cleaning brush 41, thereby deforming the cleaning brush 41. Subsequently, when the cleaning brush 41 passes by the baffle 5, the cleaning brush 41 resumes, thereby causing the cleaning brush 41 to shake, so that the solid particles attached to the cleaning brush 41 are shaken off, thereby improving the cleaning efficiency.

[0032] Furthermore, a plurality of cleaning blocks 6 are fixedly arranged on the upper surface of the baffle 5, and the plurality of cleaning blocks 6 are arranged in an array on the upper surface of the baffle 5.

[0033] As Figure 2 、 3 shown, when the cleaning brush 41 passes by the baffle 5, the plurality of cleaning blocks 6 clean the solid particles attached inside the cleaning brush 41, thereby further improving the cleaning efficiency.

[0034] Furthermore, a water flow sensor 7 is installed on the inner wall of the discharge pipe 13, and a time relay 71 is installed on the upper surface of the filter cylinder 1; the water flow sensor 7 is electrically connected to the input end of the time relay 71, and the motor 21 is electrically connected to the output end of the time relay 71.

[0035] As Figure 1 、 2As shown in Figure 4, when the staff imports raw materials into the filter cartridge 1, when the water flow passes through the discharge pipe 13, the water flow sensor 7 is activated (model: SCG-1-T69-1). At this time, the time relay 71 starts timing (model: JSZ3A). During this process, the liquid in the raw materials has been discharged from the filter cartridge 1 through the discharge pipe 13. Subsequently, after reaching the time set by the time relay 71, the motor 21 is started, and then the scraping assembly 2 scrapes the solid particles on the outer wall of the solid-liquid separator. During this process, there is no need for the staff to start manually, thereby reducing the work difficulty of the staff.

[0036] Furthermore, a drain valve 8 is installed on the outer wall of the drain pipe 4.

[0037] As Figure 2 shown, by means of the drain valve 8, the probability of the liquid being discharged through the drain pipe 4 during the separation process is reduced, thereby improving the separation efficiency.

[0038] Embodiment 2

[0039] As another implementation manner of the present utility model, a plurality of steel brushes 9 are fixedly arranged on the bottom surface of the connecting frame 22. The plurality of steel brushes 9 are all in contact with the outer wall of the solid-liquid separation cylinder 11, and the steel brushes 9 and the cleaning brush 41 are fixedly connected to each other. The user can select the scraper 23 or the steel brush 9 according to the type of the raw materials to scrape different solid particles, thereby improving the practicability of the device.

[0040] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated. There are various detachable installation methods. For example, it can be by means of the cooperation of plugging and buckling, or by means of bolt connection and other methods.

[0041] The above embodiments' specific description of the present utility model is only used to further illustrate the present utility model and cannot be understood as a limitation on the protection scope of the present utility model. Any non-essential improvements and adjustments made by those skilled in the art according to the content of the above utility model fall within the protection scope of the present utility model.
