Description

Technical Field

[0001] This utility model relates to the field of proppant production technology, specifically to a drying device for semi-finished ceramic proppant. Background Technology

[0002] Ceramsite proppant is a type of artificial ceramic particle made primarily from bauxite and other raw materials through high-temperature sintering. It is mainly used in hydraulic fracturing operations in oil and gas fields to support fractures and increase well production. Drying ceramsite proppant is a crucial step in its production process. The main purpose of drying is to remove moisture from the semi-finished ceramsite proppant, ensuring its chemical stability and preventing cracking or strength reduction due to moisture evaporation during subsequent high-temperature calcination.

[0003] By contacting the ceramsite proppant semi-finished product with hot air, the hot air removes the moisture from the ceramsite proppant semi-finished product. This is one way to dry the ceramsite proppant semi-finished product. However, when the ceramsite proppant semi-finished product is dried in the drying device, the contact area with the hot air is small and the contact time is short, making it difficult to be dried continuously and comprehensively by the hot air, resulting in low drying efficiency of the ceramsite proppant semi-finished product. Summary of the Invention

[0004] This invention addresses the problem of continuous and comprehensive contact between ceramsite proppant semi-finished products and hot air during drying; it provides a drying device for ceramsite proppant semi-finished products, which can improve the drying efficiency of ceramsite proppant semi-finished products.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] A drying device for semi-finished ceramsite proppant includes a shell, with a hopper connected to the upper end of the shell and a discharge gate at the lower end. It also includes drying components and push plates. Drying components are symmetrically arranged in the front and rear parts of the shell. The rear drying component includes an arc plate and a connecting plate. The arc plate protrudes rearward, and its left end is connected to the left side plate of the shell. The upper and lower ends of the front arc surface of the arc plate are connected by a connecting plate, which has evenly distributed air holes. The cavity between the connecting plate and the arc plate is sealed at both ends by sealing plates. A hot air blower is provided on the shell to introduce hot air into the cavity between the connecting plate and the arc plate. The arc plates on the two drying components are on the same ring. Multiple push plates are rotatably arranged inside the shell outside the arc plates of the two drying components. The width of each push plate corresponds to the distance from the rear arc plate to the shell.

[0007] Furthermore, the front end of the air holes on the rear drying component is tilted upward, and each air hole is provided with a mesh screen.

[0008] Furthermore, the hot air blower corresponding to the rear drying component is fixed to the left side of the housing. The air outlet of the hot air blower passes through the left side plate of the housing and the sealing plate on the left side of the rear drying component. The air outlet of the hot air blower connects to the cavity between the connecting plate and the arc plate.

[0009] Furthermore, the lower front and rear parts of the peripheral wall of the shell are supported by support plates; the rings containing the arc plates on the two drying components are coaxial with the shell; there is a gap between the right end of the arc plate on each drying component and the right side plate of the shell.

[0010] Furthermore, a rotating plate is provided inside the housing on the right side of the two drying components. A motor is fixed to the right side plate of the housing. The output end of the motor passes through the right side plate of the housing and connects to the rotating plate. The right ends of multiple push plates are fixedly connected to the rotating plate. The inner end of each push plate faces the central axis of the housing, and the left end of each push plate slides in contact with the left side plate of the housing.

[0011] Furthermore, the discharge port of the hopper is located directly above the two drying components.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] This invention allows the semi-finished ceramsite proppant to be dried by the hot air discharged from the two drying elements as it falls between them. Furthermore, multiple rotating push plates enable the semi-finished ceramsite proppant to be continuously and repeatedly dried by the hot air discharged between the two drying elements, thus ensuring continuous drying of the semi-finished ceramsite proppant and improving its drying efficiency.

[0014] This invention facilitates the unloading of the ceramsite support agent semi-finished product after drying. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] like Figures 1-6 As shown, a semi-finished ceramsite proppant drying device includes a shell 1, which is a cylinder with its left end opening blocked by a left side plate. The upper end of the shell 1 is connected to a hopper 2, and the lower end is provided with a discharge gate 3, which can be closed or opened. It also includes drying components and a pusher plate 9. Drying components are symmetrically arranged in the front and rear parts of the shell 1. The rear drying component includes an arc plate 4 and a connecting plate 5. The arc plate 4 protrudes rearward, and its left end is connected to the left side plate of the shell 1. The upper and lower ends of the front arc surface of the arc plate 4 are connected via the connecting plate 5. The connecting plate 5 is a rectangular plate with air holes 6 evenly distributed on it. The cavity between the connecting plate 5 and the arc plate 4 is sealed at both ends by sealing plates 7. The housing 1 is equipped with a hot air blower 8 for introducing hot air into the cavity between the connecting plate 5 and the arc plate 4. The arc plates 4 on the two drying components are on the same ring. Multiple push plates 9 are rotatably arranged inside the housing 1 outside the arc plates 4 of the two drying components. The push plates 9 are rectangular plates and are arranged in a ring array. The width of each push plate 9 corresponds to the distance from the rear arc plate 4 to the housing 1.

[0024] The front end of the air hole 6 on the drying component is tilted upward, and each air hole 6 is provided with a partition 10. The partition 10 can prevent the semi-finished ceramic proppant from passing through the air hole 6.

[0025] The hot air blower 8 corresponding to the drying component at the rear is fixed to the outside of the left side of the housing 1. The inlet end of the hot air blower 8 is located outside the housing 1, and the outlet end of the hot air blower 8 passes through the left side plate of the housing 1 and the sealing plate 7 on the left side of the rear drying component. The outlet end of the hot air blower 8 connects to the cavity between the connecting plate 5 and the arc plate 4.

[0026] The lower side of the periphery of the housing 1 is supported by a support plate 11; the ring containing the arc plates 4 on the two drying components is coaxial with the housing 1; there is a gap between the right end of the arc plate 4 on each drying component and the right side plate of the housing 1.

[0027] A rotating plate 12 is provided inside the housing 1 on the right side of the two drying components. The rotating plate 12 is a circular plate with a diameter corresponding to the inner diameter of the housing 1. A motor 13 is fixed to the right side plate of the housing 1. The output end of the motor 13 passes through the right side plate of the housing 1 and connects to the rotating plate 12. The right ends of multiple push plates 9 are fixedly connected to the rotating plate 12. The left side of the rotating plate 12 slides in contact with the right end of the arc plate 4 of the two drying components, and the right side of the rotating plate 12 slides in contact with the right side plate of the housing 1. The inner end of each push plate 9 faces the central axis of the housing 1, and the left end of each push plate 9 slides in contact with the left side plate of the housing 1.

[0028] The discharge port of the hopper 2 is located directly above the two drying components.

[0029] During use, the discharge door 3 is closed; the hot air blower 8 corresponding to each drying piece is started, and the hot air blower 8 introduces hot air into the cavity between the arc plate 4 and the connecting plate 5 of the corresponding drying piece. The hot air is discharged through the air hole 6 on the connecting plate 5. Due to the flow characteristics of the hot air and the inclined setting of the air hole 6, the hot air flows upward; at the same time, the motor 13 is started to drive the rotating plate 12 to rotate clockwise (the clockwise rotation of the rotating plate 12 is...). Figure 2 From the perspective of (the viewpoint), multiple push plates 9 rotate clockwise along with the rotating plate 12;

[0030] The semi-finished ceramsite proppant to be dried is fed into the shell 1 through the feeding hopper 2. The semi-finished ceramsite proppant flows downward between the two drying elements. Due to the upward flow of hot air between the two drying elements, the hot air comes into contact with the semi-finished ceramsite proppant flowing downward between the two drying elements, and carries away the moisture on the semi-finished ceramsite proppant upward through the feeding hopper 2. After the semi-finished ceramsite proppant flows downward into the shell 1 on the lower side between the two drying elements, due to the clockwise rotation of multiple push plates 9, any push plate 9 that moves into the lower part of the shell 1 will push the semi-finished ceramsite proppant in the lower part of the shell 1 upward and enter the shell 1 on the rear side of the rear drying element. With the movement of the push plate 9, the semi-finished ceramsite proppant moves upward to the upper side between the two drying elements. Under the action of its own weight, the semi-finished ceramsite proppant falls back into the space between the two drying elements and continues to be dried by the hot air discharged between the two drying elements.

[0031] Therefore, this utility model can drive the semi-finished ceramic proppant in the housing 1 to move downwards continuously and repeatedly through the push plate 9, thereby making the semi-finished ceramic proppant continuously and repeatedly dried by the hot air between the two drying elements. The drying of the semi-finished ceramic proppant is continuous, improving the drying efficiency of the semi-finished ceramic proppant.

[0032] After the ceramsite proppant semi-finished product is dried, the hot air blower 8 is turned off and the discharge door 3 is opened. The motor 13 continues to drive the rotating plate 12 to rotate. After the ceramsite proppant semi-finished product enters the shell 1 under the two drying components, it continues to be discharged from the shell 1 and is no longer pushed by the push plate 9. Moreover, the multiple push plates 9 rotate, so that the remaining ceramsite proppant semi-finished product that is still being driven by the push plate 9 falls between the two drying components and then enters the shell 1 under the two drying components, and is discharged through the lower part of the shell 1.

[0033] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
