[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figures 1-6 As shown, this embodiment provides an energy-saving device for a hydraulic system of a calcium carbide furnace, including a furnace body 1. Two calcium carbide outlet nozzles 2 are connected to both sides of the furnace body 1. Each calcium carbide outlet nozzle 2 is provided with a baffle 3, which is used to block the calcium carbide coming out of the furnace. A scraper 4 is slidably connected to the baffle 3, and the scraper 4 is driven to slide on the baffle 3.

[0029] Specific, the furnace body 1 is provided with a plurality of groups of lifting cylinder, a plurality of groups of lifting cylinder and hydraulic oil tank are connected through line, and in the process of line connection, the hydraulic oil is controlled by process control hydraulic valve group, and the hydraulic oil tank is provided with two pressure maintaining pumps, and the pressure maintaining pumps are controlled by hydraulic control check valve, and the hydraulic control check valve is connected with a plurality of accumulators, and a circulating oil pump is connected on another line of the hydraulic oil tank, and the circulating oil pump is provided with a hydraulic oil cooler, the hydraulic oil in the hydraulic oil tank is repeatedly pumped by the working of the circulating oil pump, so as to be cooled and cooled in the hydraulic oil cooler, when the calcium carbide in the furnace body 1 needs to be discharged, the calcium carbide is discharged out of the furnace body 1 through the calcium carbide discharge nozzle 2 communicated on the side wall of the furnace body 1, wherein one side of the furnace body 1 is provided with a support frame 5, a discharge port 6 is formed in the support frame 5, a receiving port 7 is arranged in the discharge port 6, and the receiving port 7 is connected with an external material car (not shown in the figure), and in the receiving process, the receiving port 7 is moved upward to approach the opening of the calcium carbide discharge nozzle 2 under the control of the external material car, so as to facilitate the receiving of calcium carbide. The receiving port 7 is arranged in the baffle 3, and the baffle 3 is arranged in U shape, which is used to block the falling calcium carbide. It should be noted that the calcium carbide is in liquid state when it is discharged from the calcium carbide discharge nozzle 2, and it will become solid and adhere to the baffle 3 when it splashes on the baffle 3.

[0030] The baffle 3 is connected to the discharge port 6 through a sliding block, and one side of the baffle 3 is provided with an electric telescopic rod, which is arranged on the support frame 5. When the calcium carbide is discharged, the electric telescopic rod is started to push the baffle 3 to slide horizontally in the discharge port 6, so as to approach and fit the receiving port 7 placed on the falling port, so as to shield the edge of the receiving port 7, and avoid the splashing of calcium carbide when it is discharged. The above are all prior art and will not be described in detail.

[0031] The innovation of the embodiment is that the baffle 3 is connected with a scraper 4, and the scraper 4 is driven to slide on the baffle 3.

[0032] Specifically, two first inclined surfaces 8 are formed at the two ends of the scraper 4, a connecting plate 9 is fixedly connected to the support frame 5, two fixed strips 10 are fixedly connected to one side of the connecting plate 9, and second inclined surfaces 11 matched with the first inclined surfaces 8 are formed at the ends of the fixed strips 10. Two sliding grooves 12 are formed at the opposite sides of the baffle 3, a sliding block 13 is slidably connected in the sliding groove 12, the sliding block 13 is connected with the scraper 4, and a compression spring 14 is connected to the bottom of the sliding block 13. The bottom of the compression spring 14 is connected with the bottom of the inner wall of the sliding groove 12.

[0033] In this embodiment, the scraper 4 is U-shaped, and the scraper 4 is slidingly fitted with the baffle 3, that is, the three surfaces on the baffle 3 are slidingly fitted with the three surfaces on the scraper 4, so that when the calcium carbide splashes onto the baffle 3 around the receiving port 7 during the falling process, that is, splashes onto the baffle 3 below the scraper 4, the scraper 4 pushes the calcium carbide attached to the position during the downward sliding process, thereby reducing the area of the calcium carbide attached to the baffle 3; it should be noted that the first inclined surface 8 and the second inclined surface 11 are in the same horizontal direction, so that when the electric telescopic rod pushes the baffle 3 to slide, it drives the sliding abutment between the first inclined surface 8 and the second inclined surface 11, so that the scraper 4 is passively slid downward on the baffle 3, and pushes and cleans the calcium carbide attached to the baffle 3; the connecting plate 9 is provided with a U-shaped groove, and the calcium carbide outlet nozzle 2 is abutted with the U-shaped groove to support the calcium carbide outlet nozzle 2 as a whole, so that the calcium carbide flowing out of the calcium carbide outlet nozzle 2 flows into the receiving port 7, thereby entering the material car for transportation; the sliding block 13 extends to the outside of the sliding groove 12, and one end of the sliding block 13 extending to the outside of the sliding groove 12 is connected with the baffle 3, wherein the sliding direction of the sliding block 13 is vertical sliding.

[0034] In the above description, the scraper 4 has two working states:

[0035] When the scraper 4 is in the first working state, that is, the scraper 4 is located above the baffle 3, and the first inclined surface 8 and the second inclined surface 11 on the scraper 4 are in the same horizontal direction;

[0036] When the scraper 4 is in the second working state, that is, the first inclined surface 8 and the second inclined surface 11 on the scraper 4 slide and abut, pushing the scraper 4 to slide downward on the baffle 3;

[0037] Specifically, when switching from the first state to the second state, the electric telescopic rod is started to push the baffle 3 to slide on the falling port, and the first inclined surface 8 and the second inclined surface 11 on the scraper 4 are close, and then the two slide and abut, so that the scraper 4 is passively slid downward on the baffle 3, and the sliding block 13 is pushed to slide downward in the sliding groove 12, thereby causing the compression deformation of the compression spring 14.

[0038] In the above description, the switching action from the first state to the second state is switched by the electric telescopic rod. Specifically, when cleaning the carbide, the electric telescopic rod is started to push the baffle 3 to slide on the discharge opening 6, so that the baffle 3 is close to the surrounding of the receiving opening 7 to block the carbide and prevent the carbide from splashing. During the sliding of the baffle 3, the first inclined surface 8 and the second inclined surface 11 slide and abut, forcing the scraper 4 to slide downward on the baffle 3, thereby pushing and cleaning the carbide attached to the baffle 3, avoiding that the carbide is attached to the baffle 3 in a large area.

[0039] When the carbide discharging is finished, the electric telescopic rod is started to drive the baffle 3 to slide reversely, so that the first inclined surface 8 and the second inclined surface 11 lose abutment, and under the rebound of the compression spring 14, the scraper 4 is pushed to slide upward, so that the scraper 4 slides to the initial position.

[0040] In order to improve the cleaning effect, the first inclined surface 8 and the second inclined surface 11 repeatedly slide and abut to drive the scraper 4 to repeatedly slide on the baffle 3, thereby repeatedly pushing and cleaning the attached carbide.

[0041] The beneficial effects of the embodiment are as follows: the first inclined surface 8 on the scraper 4 and the second inclined surface 11 on the fixed strip 10 are driven to slide and abut by the electric telescopic rod, so that the scraper 4 is passively slid on the baffle 3 to push and clean the large-area carbide attached to the baffle 3, thereby reducing the area of the carbide attached to the baffle 3 and avoiding the subsequent cleaning troubles.

[0042] Further, as shown in Figure 6 When the carbide splashes onto the baffle 3, the scraper 4 pushes and cleans the carbide, but after the pushing and cleaning, part of the small-volume carbide remains on the baffle 3 and cannot be pushed and cleaned by the scraper 4.

[0043] Therefore, based on the above description, the embodiment provides another cleaning structure, the scraper 4 is internally provided with a gas storage cavity (not shown in the figure), the bottom of the scraper 4 is provided with a plurality of gas injection heads 15, each gas injection head 15 is in communication with the inside of the gas storage cavity, the direction of the gas injection of the gas injection head 15 is vertical, and the scraper 4 is provided with a gas blowing pump (not shown in the figure), which is in communication with the gas storage cavity inside the scraper 4.

[0044] Specifically, the plurality of gas injection heads 15 are arranged in a vertical state and uniformly distributed on the bottom of the scraper 4; the gas outlet of the gas blowing pump is in communication with the inside of the gas storage cavity inside the scraper 4 through a pipeline, so that when the gas blowing pump sucks gas, the gas is discharged through the gas outlet, enters the inside of the gas storage cavity, and is finally injected from the gas injection head 15 to blow on the baffle 3 to clean the remaining carbide on the baffle 3.

[0045] Certain exemplary embodiments of this application are described herein by way of illustration, and not limitation, and it is to be understood that the application can be carried out with modifications in various forms within the spirit and scope of the application, as those having ordinary skill in the art with the benefit of this disclosure would understand them. Therefore, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
