Definitions

  • the invention relates to the production of building materials, in particular clay bricks, and can be used for crushing and mixing of the starting raw material, for example different clays and additives in technological production lines of ceramic mass.
  • each additional housing may be provided with its own supply device.
  • the increase in the quality of the preparation of the mixture is achieved in the known device by the successive and incremental addition of the components of the mixture, ie in the first additional housing by the supply device, the addition of one component, hereinafter the other one, etc., wherein the Mixture at the outlet of each housing is pushed through the screen by the worm and cut by the knives.
  • a constructive approach may be justified for blends of many components whose Production with different technical parameters is accompanied when one or the other component is introduced into the mixture.
  • such a design solution is not appropriate because it substantially increases the dimensions of the device and its energy consumption.
  • the closest prior art includes a housing having a worm disposed therein.
  • the housing is connected to a container in which immovable filter grids are arranged in the form of perforated discs with round openings and rotating trefoil blades whose cutting edges are arranged in an arc on the circumference.
  • the main disadvantage of the device is the low efficiency of comminution and mixing of the machined material.
  • the claimed invention solves the technical problem of increasing the efficiency of comminution of moldable material, in particular clay, wherein the notified device simultaneously fulfills the function of a mixer.
  • the object is achieved in that in the apparatus for crushing and mixing of moldable materials, mainly clay, comprising a housing with a supply container, a screw and in the housing alternately arranged non-movable transverse grating and rotating blades with cutting elements in the form of sheets, according to the invention, the knives and the transverse grids are arranged adjacent to each other, the cutting elements of the knives having surfaces extending at an angle with respect to the planes of the transverse grids between which the knife carrying them is mounted, and at the same time inclined with respect to the plane of the transverse grating that are on the path of movement of the Material after the knife follows, wherein the end edges of the cutting elements are formed so that they touch said planes of the transverse grid.
  • the distinguishing feature of the notified technical solution is the shape of the knives and their arrangement with respect to the transverse gratings. This feature is as follows: each knife is placed between two cross gratings adjacent to it, with one end edge of each cutting element of that knife touching the diametral plane of one grating and the other touching the diametral plane of the other grating. The gap between them is minimal and is selected on the condition that the rotating blades move freely with respect to the non-movable grids.
  • the cutting elements of the knives have a shape approximating the shape of a blade, with the above-mentioned end edges and with flat surfaces extending at an angle to the longitudinal axis of the device, i.
  • the above-mentioned extension and inclination of the surfaces of the cutting elements cause the material at the exit from the openings of the grid no resistance on the part of the knife undergoes, and in addition that inclined (lamellar) surface of the cutting elements, a displacement of the material in the region of acute angle between her and the diametral plane of the following grid allows.
  • the material forced through the openings of the grille enters a closed space and, in the area of the acute angle between the inclined surface of the cutting element and the plane of the cutting element Grid is not simply pressed into the openings of the grid, but is thereby subjected to a crushing action from this surface of the cutting elements, which significantly increases the efficiency of the crushing.
  • such a design and arrangement of the cutting elements ensure that the front edge of the cutting element, which is in the plane of the previous Transverse grid moves, together with the inclined surface forms an aligned in the movement path acute-angled cutting edge, which cuts the material that is pressed by the previous grid, while the opposite end edge forms an obtuse angle with the same inclined surface in the path of movement, which allows in that the material is forced through the openings of the following grid.
  • a knife is first arranged, wherein in the following plane of the transverse grid, which contacts the cutting elements, tangentially oriented grooves are formed, wherein the housing is provided with a tube, which takes
  • the device operates as a stone cutter, which makes it possible to remove all heavy large inclusions from the mass of material to be crushed, while the grooves serve as guides for these inclusions as they move towards the perimeter of the housing.
  • the grooves In order to pass these inclusions unhindered and to dissipate the circumference of the channel and then into the pipe, the grooves must be aligned tangentially.
  • This broadening may be in the form of a triangular, round, or any other profile that merges into a dimple of smaller dimensions. It is preferred that the grooves are perforated only in part of their length.
  • the knives may be four-bladed with the cutting elements staggered with respect to the cutting elements of the adjacent knives. Such dislocation allows mixing as it interrupts the streams of material and directs a portion of one stream into the mass of another.
  • the efficiency of comminution with simultaneous mixing of the material to be crushed achieves the best values when using the device with an orientation of the inclined plane of the cutting elements with respect to the plane of the transverse grating following the path of movement of the material at an angle in the range from 20 ° to 40 °.
  • the efficiency of comminution deteriorates because the mouldable material does not pass under the part of the lamellar surface of the cutting elements which has the highest degree of comminuting action, while at an angle of more than 40 ° the inclined one Surfaces of the cutting elements press the material on his path of movement worse.
  • the first knife in the movement path, it is expedient, so that it can fulfill the function of a stone separator, that this knife with respect to the plane of the transverse grid, which follows the path of movement of the material, an orientation of the inclined plane of its cutting elements at an angle in Range of 60 ° to 90 °.
  • the inclined surface oriented in this way moves most efficiently large inclusions to the peripheral area, from where they can be removed with the help of the tube.
  • the device prefferably with a means for axially pressing the entirety of the knives and grids.
  • a variant of the structural design of this means is a spacer bush, which is mounted between the arranged at the output of the device grid and a cap nut, the for a regulating displacement is arranged on the output end face of the housing.
  • the transverse gratings with a groove provided on the outer cylindrical surface at its generatrix and fixed by means of a fixing pin in the housing, which passes through said grooves and through an analog groove formed on the inner surface of the housing.
  • the fixing of the transverse grid with respect to the housing by means of opposite (ie opposite in diameter of the grid) arranged radial projections on the cylindrical surface of the grid, wherein the projections go into the longitudinal grooves, which on the inner surface of the housing opposite each other and are arranged along the generatrix of the housing.
  • the knife can be disassembled (composed of several parts or two halves).
  • the end edges of the knives which have a certain width, may partially “cut off” with a bevel directed at the end edge which cuts off the material from the plane of the previous grid to the side opposite to the direction of rotation of the knives, this slope, which in contrast is directed towards the motion side with the "opening", reinforces, with respect to the plane of the following grid, the effect of crushing the mass and its pressing by the grid.
  • the optimal size of this slope is an angle of 20 to 30 degrees, which is chosen based on experience.
  • the device for crushing and mixing of clay shown in the drawings comprises a supply container 1 and a housing 2 connected thereto, through the longitudinal axis of which passes a shaft 3 which also passes through the lower region of the container 1 and is connected to its rotary drive (FIG not shown in the drawings).
  • the shaft 3 is partially disposed in the region of the container and in the initial region of the housing relative to the path of movement of the material and provided with a screw blade 4.
  • alternately non-movable transverse grating 5 and rotating blades 6 are arranged, which are fixedly mounted on the shaft 3, for example by means of a pin connection.
  • the knives 6 see Fig.
  • the end edges 10 of these elements are the cutting edges.

  • the connection gap between them is sufficient to move these elements freely with respect to each other but is minimal to prevent material from entering into them.
  • the cutting elements 7 are offset with respect to the cutting elements of the adjacent knives, ie the adjacent knives are arranged in the housing such that the cutting elements 7, eg the straight knife, are aligned in the space between the cutting elements of the odd.
  • the lamellar surface 9 of the cutting elements forms an angle ⁇ equal to 30 degrees with the plane of the transverse grating 5 following the path of movement of the material.
  • the cross gratings are fixed by means of a fixing pin 11 in the housing, which is inserted in grooves, which are arranged on the outer cylindrical surface of the transverse grid 5 and continue (at the periphery of its cross section) on the inner surface of the housing 2.
  • a retaining grid 12 is arranged, which prevents large stones and metallic inclusions enter the working area of the screw, and also increases the reliability of the device. However, it can not always be completely ruled out that stones get into the device.
  • the first knife 6 'of this sequence in front of the first transverse grating 5.
  • the cutting elements of this knife extend at an angle of 75 degrees, and on the surface of the first transverse grid, which faces this knife, tangentially oriented grooves 13 are formed (see Fig. 5).
  • the grooves are perforated on part of their length (see Figures 6 and 7), the profile of these grooves widening in the part that opens to the plane of the grid that contacts the first knife.
  • This broadening of the cross-section may be in the form of a semicircle, a triangle or the like (see Fig. 7), ie, shapes which ensure that the grooves perform as well as stony inclusions guides as they travel around the periphery of the housing.
  • the housing is provided with a tangential tube 14 for the removal of stones and other inclusions.
  • a threaded connection of the housing 2 and the union nut 15 allows regulation of the force of this adjustment.
  • the worm in the end part 17 is conical.
  • the device works as follows.
  • the moldable starting material in particular clay
  • the clay passes through a grid into the working area of the screw 4, which pre-shreds and premixes the material and shifts the material to the first grid 5 on the path of movement or to the first knife 6 '(depending on the design of the device). Since the end part 17 of the screw 4 has the shape of a truncated cone, the clay is pre-pressed to the grid and is pushed through its openings and reaches the area of the following knife 6.
  • the surface 9 acts this Knife on the heavy inclusions, which may be in the mass of the clay, it leads along the tangential grooves 13 first to the periphery of the housing and then along its wall to the discharge pipe 14 from.
