Description

Technical Field

[0001] The utility model relates to the technical field of gypsum board preparation, in particular to an automatic discharging device for gypsum board sealing equipment. Background Art

[0002] With the development of the gypsum board industry, the market demand for paper-faced gypsum board is also increasing. The calcination of desulfurized gypsum in the production line is very important. Only by calcining qualified gypsum can the production line be stable. Due to different processes, gypsum board calcination equipment will form powder at the bottom of the equipment during the calcination process. In order to ensure the uniform fluidization of gypsum during calcination and ensure the stability of gypsum, the calcination equipment needs to be cleaned regularly.

[0003] At present, the cleaning of powder at the bottom of the equipment is usually done manually, which takes a long time and requires a lot of labor. Therefore, a discharge pipe will be connected to the bottom of the calcining equipment, and an electric control valve and a node controller will be set in the discharge pipe to control the interval time to periodically open the electric control valve, and use the internal positive pressure generated when the calcining equipment is working to automatically discharge the powder, so as to improve the discharge efficiency.

[0004] However, the electric control valve is a movable unit component, which is in contact with the powder in the discharge pipe for a long time, which can easily cause a large amount of powder to enter the movable gap of the component, causing the valve to operate poorly or even shorten its service life. Utility Model Content

[0019] 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.

[0020] like Figure 1 to Figure 2 As shown, the utility model provides an automatic discharging device for gypsum board sealing equipment, including a discharging pipeline 1 connected to the bottom of the sealing equipment, an electric-controlled valve 2 is arranged in the discharging pipeline 1, and a material introduction sleeve 3 is arranged on the discharging pipeline 1 between the electric-controlled valve 2 and the sealing equipment, a plurality of layers of serrated protrusions 4 are arranged on the inner wall of the material introduction sleeve 3, and inverted triangular grooves 5 are formed between adjacent serrated protrusions 4, and the surfaces of the serrated protrusions 4 and the inverted triangular grooves 5 are both set to be rough surfaces.

[0021] By setting the surface of the serrated protrusion 4 and the inverted triangular groove 5 to a rough surface, the airflow can make the powder adhere to its surface when it passes through the discharge pipe. Further setting the serrated protrusion 4 and the inverted triangular groove 5 with depth and height can increase the contact area with the airflow, so that the guide sleeve 3 can absorb and store more powder, thereby reducing the amount of powder contacted by the rear electric control valve 2, thereby improving the problem of the valve movable part being stuck due to the accumulation of a large amount of powder. At the same time, the serrated protrusion 4 and the inverted triangular groove 5 are provided with multiple layers, and the adjacent repeated design makes the powder blocked and stuck therein when moving, so as to better retain the powder and prevent it from flowing smoothly downward and contacting the electric control valve 2.

[0022] Further, specifically, the discharge pipeline 1 includes a first section 6 and a second section 7, the first section 6 is connected to the sealing device, the second section 7 extends outward, the first section 6 and the second section 7 are connected through the guide sleeve 3, and the two ends of the guide sleeve 3 are detachably connected to the ends of the first section 6 and the second section 7.

[0023] The material introduction sleeve 3 can be arranged as described in the above embodiment, and can be detachably arranged between the first section 6 and the second section 7. Thus, it can be removed regularly, cleaned and removed for reuse. This can achieve better use effects. There are many ways of detachable connection, such as threaded connection, external ferrule fixing, etc.

[0024] Furthermore, the guide sleeve 3 is provided with a plurality of bends 8. When the airflow passes through the bends 8, it will slow down and the powder will accumulate at the bends 8, thereby achieving the purpose of accumulating the powder. In actual production, the bends 8 can also be separately set as detachable parts, which can be movably removed for cleaning.

[0025] In addition, a reflow sphere 9 is provided between two adjacent bends 8 on the guide sleeve 3, and the sawtooth protrusion 4 and the inverted triangular groove 5 are provided on the inner wall of the reflow sphere 9. The depth of the sawtooth protrusion 4 and the inverted triangular groove 5 on the reflow sphere 9 is deeper.

[0026] A reflux plate 10 is provided on one side of the reflux ball 9 in the material introduction sleeve 3 , and an end of the reflux plate 11 is bent back toward the reflux ball 9 to form a reflux bend 11 .

[0027] The feature of the reflux ball 9 is that the depth of the sawtooth protrusion 4 and the inverted triangle groove 5 provided thereon is deeper than that of the sawtooth protrusion 4 and the inverted triangle groove 5 on the wall of the introduction sleeve 3, thereby increasing its surface area and enabling it to continue more powder. In other words, the reflux ball 9 can actually be used as a larger cavity that can continue more powder.

[0028] Furthermore, a reflow sheet 10 is provided on one side of the reflow sphere 9, downstream of the airflow direction, and its end is bent back toward the reflow sphere 9 to form a reflow bend 11, as shown in FIG. Figure 1 As shown, this means that when the airflow passes through this place, under the guidance of the reflux sheet 10, the airflow will reflux, so that the airflow mixed with the powder in the central part of the pipeline that has not contacted the serrated protrusions 4 and the inverted triangular grooves 5 can return again and collide and mix with the airflow behind, thereby dispersing in the reflux sphere 9, and then the serrated protrusions 4 and the inverted triangular grooves 5 in the reflux sphere 9 can contact more airflow, thereby being able to absorb more powder.

[0029] Like the bend 8, the reflux ball 9 can also be arranged to be detachable during actual production, so as to facilitate cleaning.

[0030] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
