Description

A device for packing kinematically viscous products

The invention relates to a metering technique and can be used to pack kinematically viscous products.

A device is known for filling liquid and pasture products containing a supply tank, a casting head mounted on it, including a 1-spool mounted rotary valve with channels for product passage and a drain TUBE mounted under it, and a metering cylinder. (Мс1шины FKPG models. Prospectus of the BOSCH FIRM, Germany. 1983)

In the described construction, the packaged liquid, pulled out of the drain PIPE in a mono flow, hits the bottom of the tank used to fill the tank with foaming and spraying liquid. In addition, the design does not provide for the elimination of drop formation.

A device is known for packaging liquid and pasta-like products, comprising a supply tank, a casting head mounted on it, including a spool mounted with rotation channels with channels for product passage, a drain pipe installed underneath it, mounted at the outlet from it with the possibility of closing the last locking element with FLEXIBLE element connected to the spool and passing through one of the channels for the passage of the product, and a metering cylinder (A.S. 1640100, V67sZ / 04, vol. 07.04.91

BULL.Y 13).

In the described device, the proposed design of the locking body is not effective enough when packaging pasta-shaped products. In addition, the locking body, forming an obstacle to the mono flow of the liquid product being packaged, changes the direction of its inner cylindrical layers, which, when colliding with neighboring ones, cause a violation of the laminar flow.

The purpose of the invention is to increase the processability of the packaging process.

This is achieved by the fact that in the device for packing kinematically viscous products containing a consumable tank with a float, a dispensing regulator, packing heads connected to the tank, each of which includes a measuring cylinder with a pneumatic cylinder, the stroke of which is limited by the metering regulator, a spool with with channels for the passage of the product, mounted with the possibility of rotation, and a drain PIPE, to the latter are attached coaxially with the Formation of the internal drain channel damping with drain holes and a removable nozzle EQUIPPED with a removable dropping holder in the form of at least one mesh element, the area of which corresponds to the flow rate of the packaged product, and the length of the drain channel from the drain holes of the damper to the mesh element must howl more than 0.7 times the diameter of the radial holes of the damper and less the diameter of the drain channel.

The damper can be made in the form of a glass with drain holes radially located in its bottom part, and the mesh element can have a U-shaped cross section, and the curvature of its surface and the size of the mesh cells are proportional to the viscosity of the packaged product. The installed damper, creating a barrier to the mono-flow of the packaged product, extinguishes its initial energy and, for example, with radial openings forms a laminar flow evenly distributed over the drain channel.

To ensure unhindered passage of the product through the droplet holder during packing, the mesh element has an area corresponding to the flow rate of the packaged product. This is achieved, for example, by making a U-shaped cross section of the mesh element. In addition, this is achieved by the corresponding mesh size of the mesh element. The curvature of the cross section and the mesh size of the mesh element are proportional to the viscosity of the packaged product.

The length of the drain channel from the merging holes of the damper to the mesh element should be greater than 0.7 of the diameter of the drain holes of the damper and less than the diameter of the drain channel, which contributes to a quiet liquid along the walls of the drain channel without any pressure loss. When the channel length is less than 0.7 of the diameter of the drain holes of the damper, the cross sections of the flows arising from the latter are extremely compressed, and their outflow rates are consequently increased. With the length of the channel. Larger than 0.7 of the diameter of the drain holes of the damper, the compressed minimum flow cross sections gradually expand. Streams are straightened and become allelic pairs. The outflow takes on a laminar character. With the length of the drain channel. Larger than its diameter, there is a further undesirable expansion of the merged flows with their deviation along the parabola down, which entails the emergence of additional resistance and loss of pressure.

Figure 1 shows a General view of the device for packing kinematically viscous products, figure 2 - packing head.

A device for packing kinematically viscous products SODE-Gives a supply tank 1 with attached packing heads 2, each of which includes a graduated cylinder 3 with: a piston 4, a cylinder-rod 5 that interacts with the metering regulator 6, mounted for rotation with a spool 7 s channels 8, identifying sections a, b and c for the passage of the product, a drain pipe 9, coaxially mounted on it a damper 10, made in the form of a glass with radial c:) inversions in its bottom part, and a compression nozzle C, with the formation of internally th drain channel. The diameter of the drain channel is equal to the diameter of the drain pipe described device, and the length. More than 0.7 diameter of the drain holes of the damper, but less than its diameter. In the body of the nozzle C, air inlet ducts 12 and a cavity 13 are made for accommodating the neck portion of the filled tank. E: {inside the nozzle is located interchangeable holder 14.

The device is as follows.

The product to be packaged from the supply tank 1 is pushed into the cavity of the graduated cylinder 3 by the piston 4 under the influence of the pneumatic cylinder 5, passing sections to and from the GOLD channel 8, combining: the reservoir with the cavity of the graduated cylinder.

The stroke of the pneumatic cylinder 5 is limited by the dosing regulator 6 and corresponds to the portion size of the packaged product.

The pneumatic cylinder-rod 5 is controlled by an electric pneumatic distributor, which prevents the valve 7 from switching to the discharge of the packaged product in the absence of a container for filling under

Drain PIPE 9.

At the end of the bulk portion of the product into the cavity of the graduated cylinder 3, the spool 7 is rotated, for example, with the TWO-ANGLE sprocket. In this case, the cavity of the measured cylinder is connected to the cavity of the drain TUBE 9 by means of sections a and into the channels of the spool. Piston 4 is the product is squeezed from the cavity of the measuring cylinder into the drain, in which a single flow of liquid, hitting the bottom of the damper 10, extinguishes its initial energy.

displaced from the filled tank, passes. into the channels 12 of the nozzle body into the atmosphere.

When changing the size of the container used for filling, the nozzle installed on the drain pipe of the packing head is replaced, and when the viscosity of the packaged product is changed, the droplet holder is replaced.
