Definitions

  • the invention relates to a device of considerably simplified construction and of great reliability, for the distribution of pasty products, such as plasters or mortars, which are used for example in the building industry for plastering walls and floors.
  • plasters or mortars which are used for example in the building industry for plastering walls and floors.
  • a device for the distribution of pasty products such as mortars an plasters, particularly for building works, comprising a container provided with one upper opening and equiped at the bottom with an oblique extension cone which ends in a nozzle for the delivery of the product, and with an ejection nozzle located axially inside said cone and orientated in the direction of the discharge nozzle of the device and connected to a pipe which in turn is connected to a source for delivery of air at suitable pressure.
  • this device is not adapted for the distribution of comparatively dense materials, nor it is adapted to be portable.
  • From DE-A-894 761 is also known a device for the distribution of pasty products.
  • this device is not adapted for the delivery of continuous flow of product for the plastering of channels in pavements and walls.
  • the device according to the invention aims to obviate to the drawbacks of the said prior art devices, by providing a container for the pasty product to be distributed and from which the product is delivered through a lower tapered nozzle and by means of a compressed-air ejector, as defined in claim 1.
  • the device comprises a container 1, for example with a capacity of roughly 4-5 litres, open at the top,and provided sidewise with a handle 2.
  • the container 1 is formed at its bottom with a conical extension 101, the axis of which is for example inclined at roughly 120° with respect to the vertical axis of the container 1.
  • the extension 101 ends in a nozzle 3 of the desired width.
  • the conical extension 101 will be referred to using the simplified term "cone”.
  • the container 1 has an essentially round upper mouth 201 and ends at the bottom in an essentially elliptical shape 301, to which the cone 101 is connected.
  • the mouth 201 of the container 1 is inclined, with the top part located at the portion diametrically opposed to the handle 2 to avoid leaks of product from the container during the plastering of horizontal surfaces, for which the device requires a relative forward inclination.
  • the operator controls the device by holding it with one hand by the cone 101 and with the other hand by the handle 2, on which a valve means 4 is mounted, connected by means of a flexible pipe 5 to a source of compressed air, for example to a compressor.
  • the valve means 4 can be opened and closed by means of a control 104 which is connected to a metal pipe 6 of suitable section which is orientated downwards and, with a small S-shaped bend 106, enters the cone 101 laterally through a hole 7 and an associated lateral sealing plug 8.
  • the end part of the pipe 6 which is inside the cone 101 forms an ejection nozzle 206 which is orientated towards the nozzle 3, at a suitable distance D from it, and which is essentially on the axis of the cone 101.
  • Height of the container 1 roughly 26 cm. Width of the mouth 201 roughly 15 cm. Size of the base 301 roughly 15x10 cm. Average length of the cone 101 roughly 20 cm. Width of the nozzle 3 roughly 2 cm. Distance D roughly 5-6 cm. Internal diameter of the pipe 6 roughly 4 mm. Pressure of air fed to the valve means 4 preferably not less than 2 atm., for example roughly of the order of 3-5 atm.
  • the device designed in this way functions in the following manner.
  • the pasty product which is admitted into the container 1-101 has a density such that it uniformly fills the volume employed.
  • the valve means 4 opens and a jet of air emerges from the nozzle 206 of the pipe 6, which finds least resistance in the direction of the nozzle 3 and which therefore pushes the product in front to emerge from said nozzle.
  • the jet of air is continuous, the flow of the pasty product which emerges from the nozzle 3 is also continuous, as the product upstream of the nozzle 206 flows continuously downwards on account of its own weight and especially as a result of the cavitation created by the product itself which emerges from the nozzle 3.
  • the operator will act to position and slide the nozzle 3 of the device in the channels of the pavement or of the wall to be plastered and the same operator will periodically act to resupply the container 1 with product.
  • the device can be equipped with a shoulder strap (not shown) to avoid the weight of the assembly bearing completely on the arms of the operator, in particular during wall plastering operations.
  • the same device can furthermore, during operations to plaster horizontal surfaces, be mounted via suitable articulations on a small trolley or on a slide which rest and slide on the pavement to be plastered.
  • the nozzle 10 is narrower than that 3 and is further away from the ejection nozzle 206 and since the thrust of the air delivered by this nozzle would no longer be capable of ensuring the correct delivery of the product from said nozzle, there is the possibility of removing the pipe 6 from the valve means 4, of pulling it out of the plug 8 and of replacing it with another pipe of appropriate dimensions (in both length and section), in which the ejection nozzle 13 is located in the position necessary to ensure the correct delivery of product from the new nozzle 10.
  • Figure 3 illustrates an alternative embodiment according to which the cone 101 ends, immediately upstream of the nozzle 206 of the pipe 6, with a flange 14 to which it is possible to fix a complementary flange 15 of a suitable spout 16, these flanges being arranged for removable mutual joining, for example with a bayonet connection, so that the same spout 16 can be replaced with other spouts having a nozzle 17 with a suitable section depending on the particular application and so as to allow easy cleaning of said nozzle each time the device is used.
