[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Embodiment 1:

[0035] like Figures 1 to 6As shown, the utility model provides a suspended sulfur filtering device for semi-water gas desulfurization liquid, including a base frame 1, which is firmly mounted on the ground through the legs thereon, and a filter plate 3 is arranged inside the base frame 1, and the filter plate 3 can filter the suspended sulfur in the desulfurization liquid. A plurality of drain ports 2 are opened on the base frame 1, and the filtered liquid will be discharged through the drain ports 2, thereby realizing the filtering of the suspended sulfur.

[0036] A feeding assembly 6 is also rotatably connected to the interior of the base frame 1, and a scraper 7 is fixedly connected to the feeding assembly 6. The feeding assembly 6 can rotate inside the base frame 1 based on the axis of the base frame 1. During the rotation, the feeding assembly 6 can evenly discharge the desulfurization liquid to be filtered into the interior of the base frame 1, thereby improving the filtering effect.

[0037] The base frame 1 is also provided with a mounting groove 5, and an auger 4 is installed inside the mounting groove 5. The scraper 7 can scrape the suspended sulfur on the filter plate 3 into the interior of the mounting groove 5 in the process of following the movement of the feeding component 6. The suspended sulfur entering the interior of the mounting groove 5 will be transported to the outside of the base frame 1 by the auger 4. When the feeding component 6 moves to a certain range on both sides of the mounting groove 5 (for example, when the angle between the center line of the feeding component 6 and the center line of the mounting groove 5 is less than 50 degrees, the feeding component 6 stops working, that is, Figure 1 Within the shaded range shown), it can be ensured that the desulfurized liquid will not be discharged directly through the installation groove 5, thereby affecting the filtering work.

[0038] The lower side of the base frame 1 is also fixedly connected to a suction frame 8, which is communicated with an external negative pressure device, and the base frame 1 is communicated with the suction frame 8 through the drain port 2. The external negative pressure device can keep the interior of the suction frame 8 in a negative pressure state, so that the liquid in the desulfurization liquid can pass through the filter plate 3 faster to complete the filtration work, thereby improving the filtration efficiency.

[0039] The feeding assembly 6 is driven by a feeding motor 9 installed inside the base frame 1, and the auger 4 is driven by a discharge motor 10 installed inside the base frame 1. The feeding motor 9 and the discharge motor 10 are electrically connected to an external power source through cables.

[0040] Embodiment 2:

[0041] The feeding assembly 6 includes a base plate 601, one end of the base plate 601 is fixedly connected to the motor shaft of the feeding motor 9, and the other end is overlapped on the peripheral side wall of the base frame 1, and balls 605 are installed on both ends of the base plate 601, one ball 605 is in conflict with the boss on the base frame 1, and the other ball 605 is in conflict with the peripheral side wall of the base frame 1, and a feeding frame 602 is installed on the base plate 601. The upper side of the feeding frame 602 is connected to the external feeding equipment through the connecting pipe 603. The external feeding equipment can input the desulfurization liquid to be filtered into the interior of the base frame 1 through the connecting pipe 603 and the feeding frame 602. The desulfurization liquid entering the base frame 1 is filtered under the action of the filter plate 3, and the suspended sulfur remains above the filter plate 3, and the filtrate is discharged from the drain port 2.

[0042] The scraper 7 is fixedly connected to the feeding frame 602 and fits with the filter plate 3. The lower side of the scraper 7 is inclined along the rotation direction of the feeding assembly 6. Figure 4 and Figure 6 As shown, the rotation direction of the feeding assembly 6 is Figure 4 The direction of the arrow is Figure 4 In the clockwise direction, the lower side of the scraper 7 is toward the adjacent Figure 4 The cleaning effect of the scraper 7 can be better.

[0043] The upper side of the feeding frame 602 is folded to both sides to form a "T" shape, and a spring 604 is connected between the folded part of the feeding frame 602 and the base plate 601. The spring 604 has a tendency to pull the feeding frame 602 downward. Under the pulling force of the spring 604, the scraper 7 will press against the filter plate 3, thereby further improving the cleaning effect of the scraper 7.

[0044] Embodiment three:

[0045] A pressing plate 11 is fixedly connected to one side of the feeding frame 602 away from the scraper 7. The pressing plate 11 is symmetrical with the scraper 7 with the center of the feeding frame 602 as the reference. When the feeding frame 602 moves inside the base frame 1, the pressing plate 11 can be driven to move. The pressing plate 11 is located at the feeding frame 602. Figure 4 In the counterclockwise direction shown, after the feeding frame 602 discharges the desulfurization liquid to be filtered into the interior of the base frame 1, the pressing plate 11 can spread the desulfurization liquid evenly, so that the filtering work can be better performed. The pressing plate 11 is made of elastic material and can swing upward to produce elastic deformation when subjected to pressure. While playing the role of spreading the liquid evenly, it can move better inside the base frame 1.

[0046] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
