Aerodynamic container for pneumatic mail

Abstract

This utility model relates to container devices for transporting cargo through pneumatic tube pipelines and can be used in industrial and laboratory systems, including for transporting material samples and specimens. The aerodynamic pneumatic tube container comprises a housing and end-cap elements. Each end-cap element consists of a head, a head cover, and a baffle plate, with cutouts provided on the head and baffle plate. The technical result of this utility model is a reduction in air resistance as the container moves through the pneumatic tube pipeline. By reducing air resistance as the container moves through the pipeline, the container's speed in the pneumatic tube pipeline increases and wear on the pipeline is reduced.

Description

[0001] Field of technology to which the utility model belongs

[0002] The utility model relates to container devices for transporting goods through pneumatic mail pipelines and can be used in industrial and laboratory systems, including when transporting samples and specimens of materials.

[0003] Technology Level

[0004] A pneumatic mail container is known according to Russian Federation Patent No. 2555888, published on July 10, 2015, comprising a cylindrical hollow body, a locking end element made in the form of a conical cover, the cone facing inside the body, connected to a movable rod, spring-loaded by a compressed spring, located along the axis of the container inside the sleeve, wherein the movable rod has a support ring in its lower part and is placed inside the spring, enclosed between the support ring of the rod and the end of the sleeve, wherein one of the ends of the rod, having a pressure pad, freely protrudes beyond the end of the body by the amount of the stroke of the rod.

[0005] The specified container has features that coincide with the essential features of the utility model (a cylindrical hollow container, a locking end element), and is the closest analogue of the utility model.

[0006] The disadvantages of the known solution are increased air resistance in the pneumatic tube pipeline, resulting in low movement speed, as well as insufficient tightness, which leads to losses of the transported material and increased wear of the pneumatic tube guide pipe.

[0007] The technical problem, the solution of which is provided by the implementation or use of the utility model, is the creation of an aerodynamic container for pneumatic mail with reduced air resistance in the pneumatic mail tube, which leads to an increase in the speed of its movement and a decrease in wear of the guide tube of the pneumatic mail pipeline.

[0008] Disclosure of the essence of the utility model

[0009] Technical result of the utility model: reducing air resistance when a container moves in a pneumatic mail pipeline

[0010] As a result of reducing air resistance when the container moves in the pipeline, the speed of movement of the container in the pneumatic tube pipeline increases and wear of the pipe is reduced.

[0011] An additional technical result is to increase the tightness of the container structure.

[0012] In order to achieve the technical result in an aerodynamic container for pneumatic mail, containing a housing and locking end elements, according to the utility model, each locking end element consists of a head, a head cover and a baffle, while cutouts are made on the head and baffle.

[0013] The cutouts on the head and bumper optimize airflow: the high-pressure zone in front of the container is reduced and becomes more rarefied due to the cutouts, reducing air resistance. The cutouts also increase the high-pressure zone behind the container, increasing the contact area and allowing for higher speeds. Furthermore, the effect of lowering the air pressure in front of the container and increasing the pressure behind the container as it moves allows the airflow to act as a lubricant, reducing wear on the pneumatic line.

[0023] Implementation of a utility model

[0024] The aerodynamic pneumatic tube container consists of a housing 1 and two end caps. Housing 1 is designed as a tube. The tube can be made of polyethylene, including low-density polyethylene. The end caps are located on each side of housing 1.

[0025] Each shut-off end element consists of a head 2, a head cover 3, and a bumper 4. Head 2 provides guidance and orientation within the pneumatic tube pipeline. Head cover 3 closes the container and ensures its tightness. Bumper 4 acts as a damper or shock absorber when the container stops, reducing speed. Head 2 and head cover 3 are connected to each other by threads. Head cover 3 and bumper 4 are connected with adhesive. Head 2 is attached to body 1 by welding. The welding location is shown in Fig. 1.

[0026] The head 2 and the bumper 4 have cutouts 5. They perform the function of an air cavitator.

[0027] Container components: head 2, head cover 3, and baffle 4 are made of polyamide. Elastomized polyamide 6 (PA6-EM-4) can be selected as the polyamide.

[0028] The device operates as follows.

[0029] In its initial position, the container is closed with lid 3. To load material, lid 3 is opened manually, the material is placed inside body 1, and lid 3 is then closed. The container is placed in the pneumatic tube pipeline. When compressed air is applied (or a vacuum is created), the container begins to move within the pneumatic tube pipeline. Thanks to cutouts 5 on head 2 and baffle 4, the air flow is optimized: the high-pressure zone in front of the container is reduced and becomes more rarefied due to cutouts 5, which reduces air resistance. Cutouts 5 also increase the high-pressure zone behind the container, as they increase the contact area and allow for higher speeds. Furthermore, the effect of air vacuum in front of the container and increasing pressure behind the container during movement allows the air flow to act as a lubricant, which reduces wear on the pneumatic tube.This effect is only possible with this design of the aerodynamic container.

Claims
