Detailed Implementation

[0023] Example 1: As Figure 1 As shown, a castable drying device includes a drying body 1 with an inlet 10 at the upper end and an outlet 11 at the lower end, and a gradient drying component 2 disposed within the drying body 1.

[0024] The gradient drying assembly 2 includes a vertical mounting rod 20 located at the center of the drying body 1, two umbrella-shaped material distribution plates 21 arranged from top to bottom on the outer wall of the vertical mounting rod 20, a V-shaped material distribution plate 22 located on the inner wall of the drying body 1 and between the two umbrella-shaped material distribution plates 21, and a constant temperature heating plate 23 arranged on the V-shaped material distribution plate 22 and the umbrella-shaped material distribution plate 21. The bottom end of the V-shaped material distribution plate 22 is open. The temperature of the constant temperature heating plate 23 corresponding to the V-shaped material distribution plate 22 is higher than the temperature of the constant temperature heating plate 23 corresponding to the umbrella-shaped material distribution plate 21. The constant temperature heating plate 23 adopts existing technology, such as a constant temperature graphite electric heating plate of model HK-350.

[0025] An adding cylinder 12 is installed at the upper end of the adding port 10. An installation vertical plate 13 is provided at the upper end of the drying body 1 and on one side of the adding cylinder 12. A sieve plate 120 is provided inside the adding cylinder 12. An electric telescopic rod 130 connected to the sieve plate 120 is provided on the installation vertical plate 13. A screen 121 is provided at the center of the sieve plate 120. The side wall of the sieve plate 120 extends to the outside of the adding cylinder 12. Before drying the casting material, it is added into the adding cylinder 12. The sieve plate 120 is moved left and right by the electric telescopic rod 130. At the same time, the screen 121 filters the casting material, which can remove large particles or agglomerates in the casting material. This helps to make the particle distribution of the casting material more uniform. Thus, during the drying process, the heat can be transferred to the interior of the casting material more evenly. The sieve plate 120 is a flat plate structure with a notch for installing the screen 121. The sieve plate 120 can slide left and right along the side wall of the adding cylinder 12.

[0026] like Figure 2As shown, the umbrella-shaped bulk material plate 21 is composed of three umbrella-shaped sub-plates 210 arranged from top to bottom in sequence and with increasing inner diameters, and adjacent two umbrella-shaped sub-plates 210 are connected by a first connecting ring 211. Each umbrella-shaped sub-plate 210 is provided with a constant temperature heating plate 23. When the pouring material is dried by the umbrella-shaped bulk material plate 21, the pouring material first falls onto the uppermost umbrella-shaped sub-plate 210 through the adding opening 10, and then is dispersed from top to bottom and flows through each umbrella-shaped sub-plate 210. In this process, the pouring material is dried by the constant temperature heating plate 23 on each umbrella-shaped sub-plate 210. The dispersed flow path can make each part of the pouring material more fully exposed to the heating environment. Each umbrella-shaped sub-plate 210 can provide an independent heating area for the pouring material flowing therethrough, thereby greatly increasing the overall heating area of the pouring material and helping to improve the drying efficiency. The umbrella-shaped sub-plate 210 adopts the existing umbrella-shaped plate structure.

[0027] As shown in Figure 3 The V-shaped bulk material plate 22 is composed of three V-shaped sub-plates 220 arranged from top to bottom in sequence and with gradually decreasing bottom openings. Adjacent two V-shaped sub-plates 220 are connected by a second connecting ring 221. Each V-shaped sub-plate 220 is provided with a constant temperature heating plate 23. After the pouring material is preheated by the umbrella-shaped bulk material plate 21, it first falls onto the uppermost V-shaped sub-plate 220, and then is dispersed from top to bottom and flows through each V-shaped sub-plate 220. At the same time, the temperature of the constant temperature heating plate 23 on the V-shaped sub-plate 220 is controlled to be higher than that of the constant temperature heating plate 23 on the umbrella-shaped sub-plate 210. Since the umbrella-shaped sub-plate 210 is preheated at a relatively low temperature to avoid energy waste caused by using high temperature at the beginning, a higher temperature is used on the V-shaped sub-plate 220 after the pouring material is preheated to some extent. This enables the energy to be accurately distributed according to the drying process of the pouring material, thereby improving the energy utilization efficiency. The V-shaped sub-plate 220 adopts the existing plate structure with openings at the upper and lower ends.

[0028] The drying main body 1 is provided with a mounting base 14 at the bottom end of both sides. The mounting base 14 is provided with legs 15 at the four corners, and the legs 15 are connected by a connecting rod 150. The pouring cylinder 151 is located below the discharge port 11. The mounting base 14 and the legs 15 protect and support the drying main body 1 to avoid wear and tear affecting its service life. The pouring cylinder 151 between the legs 15 can temporarily store the dried pouring material, fully utilizing the space of the equipment structure itself, and the layout is more compact with high space utilization.

[0031] S2, the screened casting material first falls on the umbrella-shaped sub-plate 210 at the uppermost end, and then is dispersed and flows through each umbrella-shaped sub-plate 210 from top to bottom, in the process, the casting material is dried by the constant temperature heating plate 23 on each umbrella-shaped sub-plate 210;

[0032] S3, the temperature of the constant temperature heating plate 23 on the V-shaped sub-plate 220 is higher than that of the constant temperature heating plate 23 on the umbrella-shaped sub-plate 210, for example, the heating temperature of the constant temperature heating plate 23 on the V-shaped sub-plate 220 is 150℃, and the temperature of the constant temperature heating plate 23 on the umbrella-shaped sub-plate 210 is 280℃, when the casting material is preheated by the umbrella-shaped sub-plate 21 and has a certain preheating basis, the casting material falls on the V-shaped sub-plate 220 at the uppermost end, and then is dispersed and flows through each V-shaped sub-plate 220 from top to bottom to continue drying;

[0033] S4, the casting material dried by the V-shaped sub-plate 220 at the bottom end falls on the umbrella-shaped sub-plate 210 at the lower end again, and continues to be dispersed and flow through each umbrella-shaped sub-plate 210 from top to bottom, and is dried at a low temperature, finally, the dried casting material is discharged from the discharge port 11 and falls into the containing cylinder 151 for temporary storage.
