Description

Technical Field

[0001] This utility model belongs to the technical field of cement loading and unloading equipment, specifically relating to a bulk loading head for cement production. Background Technology

[0002] A bulk cement loader is a specialized piece of equipment for loading bulk cement. It connects a cement silo to a bulk cement truck and uses a series of interlocking control devices to automatically load bulk cement onto the truck. It features a compact structure, large loading capacity, long travel distance, automatic control, and easy operation. It is a highly efficient, applicable, advanced, and energy-saving complete set of bulk cement loading equipment.

[0003] The bulk cement loader mainly consists of a casing, feeding hopper, loading head, drive unit, hoisting device, fan, material level indicator system, and electrical control system. Material passes through the feeding hopper and casing to the discharge port in the middle of the casing. It is then loaded into a tanker truck via an internal hose inside the loading head. Dust-laden gas discharged from the tanker truck passes through an external hose on the loading head and through the space above the inclined chute, before being discharged into the system's dust collector through a dust collection port on the fixed feeding hopper. The lower end of the loading head is detachably equipped with a bulk loading head, which is generally made of double-layered metal. The inner layer connects to the internal hose at the top, and the outer layer connects to the external hose. The bulk loading head has sufficient support to prevent hose deformation when material falls from the loading head, thus avoiding interference with material discharge.

[0004] The currently used bulk loading heads are welded double-layer structures with fixed styles and sizes. When damaged, they need to be replaced as a whole, which is costly and cannot be adapted to loading heads with hoses of different diameters, resulting in poor applicability. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bulk loading head for cement production, which solves the technical problem that the current bulk loading head is a fixed-style integrated structure, which is inconvenient to use with bulk loading machines of different specifications.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a bulk loading head for cement production, the bulk loading head including an outer cylinder and an inner cylinder sleeved inside the outer cylinder, at least three connecting members are evenly arranged along the circumference of the outer wall of the inner cylinder, a connecting seat is provided on the inner wall of the outer cylinder corresponding to the connecting members, the end of the connecting member is detachably connected to the connecting seat to realize the detachable connection between the inner cylinder and the outer cylinder, and the connecting member is telescopic.

[0007] Preferably, the connector includes a sleeve connected to the outer wall of the inner cylinder, a telescopic rod telescopically connected inside the sleeve, and a connecting block connected to the end of the telescopic rod, thereby realizing the telescopic performance of the connector.

[0008] Preferably, the connecting seat is provided with a T-shaped groove, and the telescopic rod cooperates with the connecting block to form a T-shape and is used to connect in the groove.

[0009] Preferably, the groove extends from top to bottom along the inner wall of the outer cylinder.

[0010] Preferably, the upper end of the groove is open and the lower end is closed.

[0011] Preferably, the bulk head further includes an air duct disposed inside the inner cylinder and a pressure controller disposed inside the air duct.

[0012] Preferably, the lower end of the air duct extends beyond the lower end of the inner cylinder.

[0013] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0014] This utility model features a detachable connection between the outer and inner cylinders, allowing for the fitting of outer and inner cylinders of different diameters to accommodate loading heads with hoses of varying diameters. This design offers strong applicability, and any damage to a particular part can be replaced individually, reducing costs. At least three retractable connectors are circumferentially arranged on the outer wall of the inner cylinder, with corresponding connecting seats on the inner wall of the outer cylinder. The ends of the connectors are detachably connected to the connecting seats, facilitating the matching of outer and inner cylinders with different inner diameters to accommodate loading heads with hoses of varying diameters, thus enhancing applicability.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments, and do not limit the scope of the present utility model.

[0020] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The specific implementation method is as follows:

[0023] Example 1, as Figure 1-3 As shown, a bulk loading head for cement production includes an outer cylinder 1 and an inner cylinder 3. The outer cylinder 1 is used to connect to the outer hose of the loading head. The inner cylinder 3 is sleeved inside the outer cylinder 1, with a gap between it and the outer cylinder 1, and this gap communicates with the gap between the inner and outer hoses of the loading head. The upper end of the inner cylinder 3 is connected to the inner hose of the loading head for material outflow.

[0024] In this embodiment, the outer cylinder 1 is a cone shape with varying sizes at the top and bottom, making it easy to insert into the inlet of the bulk container to be loaded with materials.

[0025] In this embodiment, the inner cylinder adopts a conical shape that is larger at the top and smaller at the bottom, which has a certain guiding effect on the material.

[0026] A connector 4 is provided on the outer wall of the inner cylinder 3, and a connecting seat 2 is provided on the inner wall of the outer cylinder 1 corresponding to the connector 4. The end of the connector 4 is detachably connected to the connecting seat 2, realizing a detachable connection between the outer cylinder 1 and the inner cylinder 3. Specifically, the connector 4 is telescopic, so that outer cylinders 1 and inner cylinders 3 with different inner diameters can be connected together, thereby adapting to loading heads with different diameter hoses and improving applicability.

[0027] In this embodiment, a bulk loading head for cement production is used by connecting the outer cylinder 1 to the lower end of the outer hose of the loading head, and the inner cylinder 3 to the lower end of the inner hose of the loading head. The bulk loading machine is then turned on, dispensing cement into the bulk containers containing the materials to be loaded. Since the outer cylinder 1 and inner cylinder 3 are detachably connected, they can be disassembled and replaced independently if damage occurs, reducing costs. Furthermore, the connector 4 is telescopic, allowing for the connection of outer cylinders 1 and inner cylinders 3 with different inner diameters to accommodate loading heads with hoses of different diameters, thus improving applicability.

[0028] Furthermore, the connector 4 includes a sleeve 41, a telescopic rod 42, and a connecting block 43. The sleeve 41 is connected to the outer wall of the inner cylinder 3, which can be achieved by welding. The telescopic rod 42 is fitted inside the sleeve 41 to achieve telescopic movement. The telescopic rod 42 and the sleeve 41 can be connected by a smooth rod friction connection or by a linear bearing, as long as they can slide against each other.

[0029] Furthermore, a groove 21 is provided on the connecting seat 2, and the cross-section of the groove 21 is T-shaped. The telescopic rod 42 and the connecting block 43 cooperate to form a T-shape, which is connected in the groove 21, realizing a detachable connection between the telescopic rod 42 and the connecting seat 2.

[0030] In this embodiment, the groove 21 extends from top to bottom along the inner wall of the outer cylinder 1, and combined with the conical shape of the outer cylinder 1, the diameter of the circle at the corresponding position of the groove 21 gradually decreases from top to bottom, and the telescopic connector 4 is used to realize the detachable connection between the inner cylinder 3 and the outer cylinder 1.

[0031] In this embodiment, the upper end of the chute 21 is open to facilitate the entry of the connector 4 into the chute; the lower end of the chute 21 is closed to support the connector 4 and realize the connection between the connector 4 and the connecting seat 2; and, since the material flows down from top to bottom during bulk loading, it has a downward impact force on the bulk loading head, so even if the upper end of the chute 21 is open, it does not affect the use.

[0032] Furthermore, the bulk loading head also includes an air duct 5 and a pressure controller. The air duct 5 is installed inside the inner cylinder 3, with one end extending out of the inner cylinder 3 and connected to a blower. A pressure controller is installed inside the air duct 5 to sense the pressure inside the air duct 5 and to indicate that the container is full. In this embodiment, the lower end of the air duct 5 slightly extends out of the lower end of the inner cylinder 3. Based on this, when the cement in the bulk container of the material to be loaded reaches the set full load height, the lower end of the air duct 5 is buried by cement, the air pressure in the air duct 5 increases, the pressure controller activates, and simultaneously sends a full load control signal to stop loading, thus completing the loading process.

[0033] Example 2: A bulk head for cement production, in which a plug is added to the upper end of the groove of the connecting seat to improve the reliability of the connection between the connector and the connecting seat. Other structures will not be described in detail here.

[0034] Example 3: A bulk head for cement production, the inner cylinder is a cylindrical shape with a consistent upper and lower diameter, and other structural details are not described here.

[0035] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
