The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0024] As shown in the figure, Figures 1 to 4As shown, including raw material bin, weighing bin, mixer, kneader, disc feeder, extruder, drying furnace, finished product bin and ton packaging device, and the raw materials are sequentially produced and packaged through the raw material bin, the weighing bin, the mixer, the kneader, the disc feeder, the extruder, the drying furnace, the finished product bin and the ton packaging device, the finished product bin includes a conveying belt 801, a bin 802, an elevator 803 and a weighing platform 804, and the conveying belt 801 is used to convey the products output by the drying furnace to the elevator 803, the elevator 803 is used to lift the products into the bin 802 for storage, and the weighing platform 804 is used to weigh the products released from the bin 802, and a buffer dispersion structure 805 is arranged at the top opening of the bin 802, and the buffer dispersion structure 805 is used to buffer the products transported by the elevator 803 and disperse the products during the buffering process, and the bin 802 is communicated with a ventilator through a pipeline, and the bottom of the bin 802 is provided with a conveying belt 815.

[0025] In actual production, first, the raw material bin is automatically fed, after the raw material bin is fed, the raw materials are transported to the weighing bin through the discharge valve, and then the raw materials are transported to the mixer through the feeding valve after being weighed in the weighing bin, mixed, and then transported to the kneader through the discharge valve after being mixed, and then the raw materials are discharged to the disc feeder, and then the products (i.e. calcium-based desulfurizer particles) are produced in the extruder, the wet material is transported to the drying furnace through the conveying belt, and then the products are transported to the top of the bin 802 through the conveying belt 801 after being dried, and then the products are temporarily stored in the bin 802 after falling from the top of the bin 802, and then the products are weighed on the weighing platform 804 and packaged by the ton packaging device when being packaged. The above is the entire production and packaging process of the product.

[0026] Among them, the raw material bin, the weighing bin, the mixer, the kneader, the disc feeder, the extruder, the drying furnace, the conveying belt 801, the elevator 803, the weighing platform 804 and the ton packaging device are all prior art, and the specific working principles of the above devices will not be described in detail here.

[0027] After the product is conveyed to the top of the silo 802 by the elevator 803, the product falls from the top of the elevator 803 to the inside of the silo 802, and the product first contacts the buffer dispersion structure 805 during the falling process, and the falling product is buffered and dispersed by the buffer dispersion structure 805, so as to avoid excessive product breakage and affect the product quality, and at the same time, the product can be dispersed, and a ventilator (not shown in the figure) is arranged, so that the product can be dried during the falling process, and the moisture of the product is reduced, and the water vapor in the product can be volatilized during the falling process. Because the product is effectively dispersed by the buffer dispersion structure 805, the drying effect of the ventilator on the product is better, which further reduces the moisture on the product, not only improves the drying effect of the product, but also improves the production quality of the product.

[0028] Further, the rubber can be laid on the inner wall of the silo 802 to buffer the product, further reducing the breakage of the product.

[0029] The silo 802 includes a first silo body 806 and a second silo body 807 in a hollow cylindrical shape and a third silo body 808 in an inverted hollow circular table shape, and the first silo body 806, the second silo body 807 and the third silo body 808 are concentrically arranged. The top of the third silo body 808 is connected with the inner wall of the first silo body 806, the second silo body 807 is in communication with the bottom of the third silo body 808, the bottom of the second silo body 807 is provided with a valve body for controlling opening and closing, the conveying belt 815 is located between the third silo body 808 and the weighing platform 804, and the first silo body 806 and the conveying belt 815 are jointly connected with a support.

[0030] The first silo body 806, the second silo body 807, the third silo body 808 and the conveying belt 815 are installed through the support, and the third silo body 808 in the inverted circular table shape can ensure that the product is discharged through the second silo body 807 under the action of gravity. The valve body is used for controlling the opening or closing of the second silo body 807, so as to control the discharging of the product or end the discharging process of the product.

[0031] The conveying belt 815 is used for conveying the product discharged through the second silo body 807 to the weighing platform 804 for weighing and packaging, and the conveying belt 815 is a prior art, which will not be described in detail here.

[0032] The buffer dispersion structure 805 includes a ring-shaped plate 809 arranged on the inner side wall of the first silo body 806, a plurality of elastic buffer strips 810 are uniformly arranged on the inner side wall of the ring-shaped plate 809 around the center of the ring-shaped plate 809, and the plurality of elastic buffer strips 810 are arranged along the radial direction of the ring-shaped plate 809.

[0033] When the product falls from the elevator 803 into the first bin body 806, it first contacts the plurality of elastic buffer strips 810. The product is dispersed by the elastic buffer strips 810, which are bent and deformed downward by the impact of the product. The product falls from the side of the elastic buffer strips 810 into the bin 802, and the elastic deformation of the elastic buffer strips 810 buffers the falling product. The product falls from the edge of the upper surface of the elastic buffer strips 810 to be dispersed, which reduces the breakage of the product and allows the product to be dispersed during the falling process and dried by the ventilator.

[0034] The elastic buffer strip 810 includes a rigid strip 811 and an elastic strip 812, and the rigid strip 811 and the elastic strip 812 are fixedly connected to the inner side wall of the annular plate 809. The rigid strip 811 is located directly below the elastic strip 812, and the distance between the rigid strip 811 and the elastic strip 812 is greater than zero.

[0035] The rigid strip 811 limits the maximum angle of downward bending and deformation of the elastic strip 812, avoiding damage to the elastic strip 812 beyond the maximum deformation limit.

[0036] The width of the rigid strip 811 is less than the width of the elastic strip 812, avoiding the accumulation of products on the rigid strip 811.

[0037] The elastic strip 812 includes two inclined plates 813 symmetrically arranged on the inner side wall of the annular plate 809. The two inclined plates 813 are inclinedly arranged on the annular plate 809, and the top portions of the two inclined plates 813 are connected. The upper surface of each inclined plate 813 is provided with a plurality of protrusions 814.

[0038] When the product falls onto the elastic strip 812, it is guided to fall by the two inclined plates 813, avoiding the accumulation of some products on the elastic strip 812. The plurality of protrusions 814 further disperses the product, reducing the adhesion between the products due to moisture.

[0039] The annular plate 809 is rotationally connected to the inner side wall of the first bin body 806.

[0040] Because the product is not evenly distributed when falling into the bin 802, the impact force of the product on each elastic buffer strip 810 is different. When the annular plate 809 is rotationally connected to the inner wall of the first bin body 806, the annular plate 809 rotates due to the different impact forces of the product on the two inclined plates 813 of the same elastic strip 812. The elastic strip 812 moves to the position, thereby buffering and dispersing the product falling between the two adjacent elastic strips 812, further improving the buffering and dispersing effect of the product.
