Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of transfer bag, concretely speaking, especially relates to a flexible transfer bag for powder particles. BACKGROUND

[0002] At present, the transportation methods for powder particle transfer mainly include powder particle special vehicle transportation and container transportation, and are mainly used in medium and large powder particle processing plants, transportation companies, logistics companies and sales enterprises, etc. However, the demand for powder particles in medium and large enterprises is large, and the transportation volume is also large. Therefore, the requirements for the transfer method and cost of powder particles are increasingly high. The powder particle transportation usually adopts the container (with disposable container liner bag) pneumatic transportation method, which uses the kinetic energy of airflow to make the bulk material in a suspended state and transported along the predetermined channel with airflow. The feeding principle is that the air-distributed powder is transported to the container-type pneumatic powder conveying device through the pipeline under the action of compressed air. After the air-distributed powder reaches the container-type pneumatic powder conveying device, it is subjected to the actions of pressure difference reduction, volume expansion, movement deceleration, gravity sinking, etc. The powder material is settled and accumulated to realize feeding. The discharge is to use the discharge connecting device to seal and connect the discharge port of the liner bag with the receiving equipment of the downstream customer. The bulk powder is transported from the liner bag to the slurry tank or other receiving container through the pneumatic conveying method. However, the above scheme has the following disadvantages: 1. Due to the existence of the liner bag, the effective loading space inside the container may not be fully utilized, resulting in a decrease in transportation efficiency; 2. When unloading the material from the liner bag, it is necessary to ensure the correct sealing of the connecting device. This process is time-consuming, and if there is a blockage problem, the unloading speed will be further reduced; 3. In order to realize efficient pneumatic conveying, additional compressed air systems, pipeline networks and other auxiliary equipment are usually required, which not only increases the initial investment, but also leads to an increase in maintenance and operation costs.

[0003] Due to the particularity of the storage and transportation medium (different media are not allowed to be mixed), the tank truck generally transports in one direction with full load, and returns empty, which directly reduces the transportation efficiency by half, i.e. the total efficiency is less than 50%. Compared with conventional ordinary transportation vehicles, the transportation efficiency is relatively low. Therefore, it is necessary to design a powder particle transfer bag with simple structure, high practicality, high structural strength and good stability, so as to be not limited to special vehicle transportation and container transportation, to adapt to different types of vehicles and to reduce transportation cost.

[0004] A powder transfer bag is disclosed in Chinese Utility Model Patent Publication No. CN 206466197 U, which can effectively prevent powder material leakage and pollution through a double-layer structure, and the outer bag surface after packaging is not contaminated, avoiding environmental pollution and personnel injury, but it has the disadvantage that the loading and unloading port cannot be quickly connected with the external pipeline, and cannot be hoisted, resulting in difficult loading.

[0031] Based on traditional transportation methods, this embodiment uses high-strength webbing 1 and high-wear-resistant flexible non-metallic bag 2 as the main structure of the transfer bag to enhance structural strength and stability, thereby not being limited by the restrictions of dedicated vehicle transportation and reducing transportation costs. On the other hand, the lifting webbing 7 enables a lifting design, reducing loading and unloading waiting time and greatly improving loading and unloading efficiency.

[0032] Example 2:

[0033] like Figure 3 As shown, a flexible transfer bag for powder and particulate matter differs from Embodiment 1 in that the flange assembly 4 includes a sealing plug 41, an intermediate flange 42 disposed outside the flexible non-metallic bag body 2, and an inner flange 43 disposed inside the flexible non-metallic bag body 2. The flexible non-metallic bag body 2 is sandwiched between the intermediate flange 42 and the inner flange 43, and a sleeve 9 is sandwiched between the flexible non-metallic bag body 2 and the intermediate flange 42. The sealing plug 41 is installed on the intermediate flange 42.

[0034] Furthermore, the sealing plug 41 is installed with the intermediate flange 42 by the first fixing screw 44, and the intermediate flange 42 is installed with the inner flange 43 by the second fixing screw 45. That is, the second fixing screw 45 passes through the intermediate flange 42, the inner flange 43 and the flexible non-metallic bag 2 on the flange assembly 4, so that the flange assembly 4 is installed on the flexible non-metallic bag 2 by the second fixing screw 45.

[0035] Further, as shown in Figure 4 The upper surface of the flexible non-metal bag body 2 is provided with a lifting tape cover 3 for placing a lifting tape 7; the lifting tape 7 is centrally symmetrically arranged, and six lifting tapes 7 are used for lifting operation, the lifting tapes 7 are fixed at the bottom, two lifting tapes 7 are arranged in the width direction and the length direction of the bottom respectively, and one lifting tape 7 is arranged at the diagonal position, so that the transfer bag is stable during lifting operation, and the lifting tape cover 3 is arranged at the top, and the lifting tape 7 is stored in the lifting tape cover 3 when the lifting operation is not performed.

[0036] Further, a disposable flexible non-metal inner layer is arranged in the flexible non-metal bag body 2, the disposable flexible non-metal inner layer is taken out from the inside through the opening of the flange assembly 4, a new disposable flexible non-metal inner layer is placed inside from the opening of the flange assembly 4, and then the disposable flexible non-metal inner layer is attached to the inside of the flexible non-metal bag body 2 by using an air source, and the opening is fixedly combined with the flange.

[0037] Further, the high-strength tape 1 and the flexible non-metal bag body 2 are fixedly connected by adhesion, high-frequency welding, heat sealing or sewing.

[0038] Further, the flexible non-metal bag body 2 has a cuboid structure, and has an outer dimension of 6m in length, 2.2m in width and 1.8m in height, a volume of 23.7 cubic meters, and can meet the requirement of a customer that the volume of the transfer bag is 22 cubic meters; in addition, the main body of the transfer bag is made of high-strength material as a sealing layer of the transfer bag, and the outside uses a high-strength binding belt as a force bearing unit.

[0039] The working principle of the utility model is as follows:

[0040] The flange assembly 4 is used for sealing and anti-tearing and reinforcing fixation of the opening part of the flexible non-metal bag body 2, is used as a main force bearing component of the opening part, and the flexible non-metal bag body 2 is clamped with a flexible sleeve 9, as shown in Figure 5 As an external interface, an external pipeline 8 is connected to the outside for loading and unloading, as shown in Figure 6 .

[0041] In use, the first fixing screw 44 and the sealing plug 41 are loosened, the sealing plug 41 is removed, then the flexible sleeve 9 is connected with the external pipeline 8 of the powder particle filling equipment, and finally the first fixing screw 44 is used to fasten the sealing plug 41 after loading and unloading are completed.

[0042] Position of the charging port 5: According to the principle of pneumatic transportation, the bulk powder is driven by compressed gas from the charging port 5 to the farthest end during loading, and the accumulation of bulk powder is realized by the effects of pressure difference reduction, volume expansion, movement deceleration, gravity sinking, etc., and the feeding is completed, so the charging port 5 needs to be arranged at the upper position of the rear end surface to facilitate feeding. The diameter of the charging port 5 is 20 cm, and a 30 cm sleeve 9 is arranged. The sleeve diameter can be customized according to needs to facilitate connection with the external pipeline 8.

The sleeve diameter can be customized according to needs to facilitate connection with the external pipeline 8.

[0044] To prevent the powder from scattering from the opening during transportation, the opening is closed and locked. Flange assemblies 4 are arranged on the inside and outside of the opening. After the sleeve 9 is tightened, it is inserted into the inside, and the two sides of the flange are tightened and fixed by screws to seal.

[0045] The flexible non-metal bag body 2 is sewn with double-layer fabric. Considering the electrostatic adsorption and permeability of bulk powder materials and the sealing performance during transportation, the inner layer is made of PVC net cloth material, and the sewing place is treated with sealing tape to ensure the overall air tightness of the transfer bag. The outer layer is the main bearing layer, which is made of high-strength fabric and treated by post-finishing to give it flame retardant, waterproof and anti-ultraviolet aging properties to ensure stability and durability. High-strength fabric belts 1 are arranged at intervals of 50 cm. After the outer layer material of the bag body and the high-strength fabric belts 1 are sewn, the whole is treated by polyurea spraying to improve wear resistance and prevent wear and tear during transportation.
