Description

Technical Field

[0001] The invention relates to a bulk material loading device for conveying granular petrochemical products to a tank truck or a container truck. Background Art

[0002] With the rapid development of the petrochemical industry, the launch of multiple integrated refining and chemical projects, and the expansion and strengthening of end-users of petrochemical products, both the manufacturers and customers of petrochemical products have a tendency to centralize and scale up.

[0003] Most chemical products produced by manufacturers are in the form of granular bulk materials. Due to the rapid growth in demand for large-scale transportation, the demand for bulk transportation using tank trucks or container trucks is also increasing.

[0004] The current common loading devices mainly focus on the docking of the loading ports. In order to fill the loading container as much as possible, multiple loading ports need to be opened on the loading container. When loading, the unloading port needs to be connected to the multiple loading ports one by one, resulting in low loading efficiency. In addition, the bulk particles fall vertically into the loading container through the loading port and are distributed in the loading container by free accumulation, which is extremely uneven and cannot fully utilize the volume utilization rate of the loading container. Summary of the invention

[0005] The purpose of the present invention is to provide a high-efficiency bulk material loading device to solve the above-mentioned technical problems existing in the prior art.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] An efficient bulk material loading device, characterized by comprising:

[0008] Flange interface, used for docking with the feed port;

[0009] The cavity has an upper end connected to the flange interface and a discharge port at the lower end;

[0010] The cone is arranged below the discharge port with the top of the cone facing upward, and is used to convert the granular bulk material falling vertically from the discharge port into being thrown obliquely in four directions.

[0011] The efficient bulk material loading device, wherein the cavity comprises:

[0012] An upper cavity, the flange interface being arranged at the upper end thereof;

[0013] A flexible connection, the upper end of which is fixedly connected and communicated with the lower end of the upper cavity;

[0014] The upper end of the lower cavity is fixedly connected and communicated with the lower end of the soft connection, and the discharge port is arranged at the lower end.

[0015] The efficient bulk material loading device further comprises a protective cover which surrounds the outer side of the flexible connection and is fixedly connected to the upper cavity.

[0017] The efficient bulk material loading device, wherein: a docking head is fixed at the lower end of the cavity for docking with the loading port of the loading container.

[0018] The efficient bulk material loading device, wherein: the discharge port is in a trumpet shape with the same inclination as the cone, so that an oblique discharge flow channel is formed between the discharge port and the cone surface of the cone.

[0019] The efficient bulk material loading device, wherein: a fixed block is fixed in the cavity, a vertically arranged bolt is provided on the fixed block, the cone is sleeved on the bolt, a nut threadedly connected to the bolt presses against the lower end of the cone, and the height of the cone can be adjusted and positioned.

[0024] The advantages of the present invention include:

[0025] 1. The direction of bulk material falling is changed from gravity to throwing along the cone direction.

DETAILED DESCRIPTION

[0032] Some specific embodiments of the present invention will be described in detail below in an exemplary and non-restrictive manner with reference to the accompanying drawings. The same reference numerals in the accompanying drawings indicate the same or similar components or parts. It should be understood by those skilled in the art that these drawings are not necessarily drawn to true scale.

[0033] like Figure 1 As shown, the efficient bulk material loading device comprises:

[0034] The upper cavity 2 has a flange interface 1 at its upper end for docking with a discharge port (generally a discharge spiral valve or a discharge pipe);

[0035] A flexible connection 4 (e.g., a serpentine tube), the upper end of which is fixedly connected and communicated with the lower end of the upper cavity 2;

[0036] The lower cavity 8 has an upper end fixedly connected to and communicated with the lower end of the flexible connection 4, and a lower end thereof is a discharge port 10;

[0037] A protective cover 3 is framed around the outside of the soft connection 4 and is fixedly connected to the upper cavity 2;

[0038] A plurality of limit baffles 5 are fixed at different height positions outside the lower cavity 8 in the horizontal direction;

[0039] The spring pin 6 is arranged on the protective cover 3, and can extend into the protective cover 3 and interfere with the lower edge of any limit baffle 5 under normal conditions; when the spring pin 6 is forced to be pulled out to a certain length, it is out of contact with the lower edge of the limit baffle 5, and the height of the lower cavity 8 can be adjusted up and down to make its height adapt to the charging port of the charging container. After the adjustment is in place, the spring pin 6 is released, and the spring pin 6 returns to the normal position under the action of the elastic force, and interferes with the lower edge of the corresponding limit baffle 5, so that the position of the lower cavity 8 is fixed;

[0040] A docking head 9 is fixed at the lower end of the lower cavity 8 and is used for docking with the charging port of the charging container;

[0041] The cone 12 is arranged below the discharge port 10 of the lower cavity 8 with the top of the cone facing upward, and is used to convert the granular bulk material falling vertically from the discharge port 10 to be thrown obliquely in four directions;

[0042] Moreover, the discharge port 10 is in a trumpet shape with the same slope as the cone 12, so that an oblique discharge channel 11 is formed between the discharge port 10 and the conical surface of the cone 12, so that the material can be more evenly thrown obliquely in four directions.

[0043] Among them, a fixing block 7 is fixed in the lower cavity 8, and a vertically arranged bolt 13 is provided on the fixing block 7. The cone 12 is inserted into the bolt 13, and a nut 14 threadedly connected to the bolt 13 presses against the lower end of the cone 12. The height of the cone 12 can be adjusted and positioned by rotation, thereby changing the vertical width of the discharge channel 11 to adjust the flow rate, and the appropriate vertical width can be selected according to the particle size of the material to achieve the best throwing effect.

[0044] In order to realize the electric adjustment of the height of the cone 12 , a motor may be used to form a power connection with the nut 14 .

[0045] In addition, in order to further enhance the scattering effect of the cone 12 on the bulk material, on the one hand, Figure 2 As shown, a plurality of guide grooves 15 arranged radially are provided on the cone surface of the cone 12. On the other hand, a rotating motor can be connected to the cone 12 so that the cone 12 can rotate around the vertical center axis and actively throw out the bulk material, thereby increasing the material discharge rate and the throwing distance. Since it is easy to connect the rotating motor to the cone 12, it is not shown in the accompanying drawings. The rotating motor can be a variable frequency motor, or a transmission can be connected between the rotating motor and the cone, so that the cone speed can be adjusted, and the material throwing distance can be adjusted online in real time.

[0046] The above description is only illustrative rather than restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the claims, but all will fall within the scope of protection of the present invention.
