Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] As Figures 1-4 shown, a technical scheme provided by the utility model comprises:

[0025] A kind of anti-clogging enamel discharge valve, including valve body 1, the bottom end of valve body 1 is detachably installed with valve cover 2, discharge pipe 3 is communicated in the right side of valve body 1, rotating rod 9 is movably installed in the middle part of valve cover 2 by bearing, threaded rod 10 is fixedly connected at the top end of rotating rod 9, the upper end of threaded rod 10 passes through valve body 1 and is located in the inside of valve body 1, hand wheel 11 is fixedly connected at the bottom end of rotating rod 9, guide block 12 is fixedly connected at the middle part outer wall of valve stem 4 both ends, guide groove 13 that is slidably connected with guide block 12 is formed in the inside of valve body 1, packing 20 is fixedly installed in the middle part of the inside of the bottom end of valve body 1, sealing ring 5 is fixedly installed at the upper end of packing 20, valve stem 4 is threadedly connected with threaded rod 10 by penetrating packing 20 and sealing ring 5 at the bottom end of valve stem 4, valve stem 4 is movably installed in the middle part of the inside of valve body 1, anti-clogging mechanism is arranged at the top end of valve stem 4, and the anti-clogging mechanism comprises anti-crystallization hole plate 6, anti-crystallization hole plate 6 is fixedly installed at the top end of valve body 1, valve core 7 is fixedly installed at the top end of valve stem 4, and a plurality of cone spikes 8 are fixedly connected to the upper end surface of valve core 7.

[0026] In the embodiment, when the valve core 7 moves upward, the spherical structure gradually separates from the anti-crystallization hole plate 6, and the discharging channel is opened. At the same time, the cone spikes 8 exert shearing force or impact force on the large crystalline bodies on the upper part and periphery of the valve core 7 during the movement, and the large crystalline bodies are broken into smaller particles, effectively preventing crystalline blockage. This design significantly improves the smoothness of the discharging channel, ensures that the material can smoothly enter the valve body 1, and solves the problem that the overall crystallization is easily formed in the central area of the bottom of the crystallization kettle due to low agitation intensity.

[0027] As Figure 1 and Figure 3As shown, a leakage prevention mechanism is arranged between the valve rod 4 and the discharge pipe 3, which comprises a valve seat 14 fixedly connected to the inner wall of the end of the discharge pipe 3 close to the valve body 1, a valve plate 15 movably mounted outside the valve seat 14, a movable frame two 16 fixedly mounted to the outer middle part of the valve plate 15, a movable frame one 17 fixedly connected to the outer wall of the right upper end of the valve rod 4, a connecting rod 18 movably mounted between the movable frame two 16 and the movable frame one 17 through a rotating shaft, and a movable frame three 19 fixedly mounted to the left side of the inside of the valve body 1 close to the valve plate 15, and the left side of the valve plate 15 is movably connected with the movable frame three 19 through a rotating shaft.

[0028] In this embodiment, when the valve core 7 descends, the spherical structure of the valve core 7 abuts against the anti-crystallization hole plate 6 to form a first resealing; at the same time, the valve plate 15 rotates and resets around the rotating shaft of the movable frame three 19 to tightly contact with the valve seat 14 to form a second resealing, and the double resealing mechanism ensures the complete sealing of the valve in the closed state, effectively prevents the medium from leaking, and improves the reliability and safety of the equipment.

[0029] Working principle: when working, first, the hand wheel 11 is rotated to drive the rotating rod 9 to rotate, and the threaded rod 10 at the top end of the rotating rod 9 is rotated accordingly; since the valve rod 4 is threadedly connected with the threaded rod 10, and the guide block 12 at the middle part of the valve rod 4 slides in the guide groove 13 on the inside of the valve body 1, the valve rod 4 will move along the axial direction of the threaded rod 10 while rotating; when the valve rod 4 moves upward, the valve core 7 at the top end of the valve rod 4 also rises; the upper end of the valve core 7 is in a spherical structure; as the valve core 7 is lifted, the spherical structure gradually separates from the anti-crystallization hole plate 6, thereby opening the discharging channel, and the material enters the valve body 1 through the discharging channel. In this process, the conical spikes 8 on the surface of the valve core 7 will exert a shearing force or impact force on the large crystalline bodies on the upper part and periphery of the valve core 7 during the movement, which will break them into smaller particles, thereby preventing clogging; the broken crystalline bodies flow downward along the discharging channel under the action of gravity. At the same time, the upward movement of the valve rod 4 drives the movable frame two 16 to move through the movable frame one 17 and the connecting rod 18, thereby pushing the valve plate 15 to rotate around the rotating shaft of the movable frame three 19, so that the valve plate 15 separates from the valve seat 14 to open the discharging channel, and the medium flows out through the discharge pipe 3. When it is needed to close the valve, the hand wheel 11 is reversely rotated, the valve rod 4 moves downward, the spherical structure of the valve core 7 abuts against the anti-crystallization hole plate 6 again to form a first resealing, which ensures that the medium will not leak through the anti-crystallization hole plate 6, at the same time, the valve rod 4 drives the movable frame two 16 through the movable frame one 17 and the connecting rod 18, so that the valve plate 15 rotates and resets around the rotating shaft of the movable frame three 19 to tightly contact with the valve seat 14 to form a second resealing, which further ensures the complete closing of the discharging channel and prevents the medium from leaking.
