Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a modular system having a drive unit, a form axis, a striking cone body, and a housing having a perforated wall so that the size of the hole can be changed during operation. This relates to the universal screw press manufactured by.

Many screw dances are known in the literature and in practice, primarily in the food and chemical industries.

A common feature of these dances is that the elementary system to be separated is carried within a housing with a perforated wall v1r by a rotating worm shaft. A conventional surface is forced in the direction of material transport, so that a squeezing effect occurs. This squeezing effect is increased by using an impact member. The solid part of the system passing through the perforated walled housing leaves the device at the impact member and loses some of its liquid-containing mass, and the liquid flows out through the perforations.

Many other examples of screw dancing are known. There are solutions which in each case contain the basic i11 elements shown, but which differ fundamentally in terms of their details and auxiliary units. A common drawback of these known devices is their inefficiency, resulting in the inability to guarantee the required organoleptic chemical purity of the separated phases; Possibilities, 1lf
It is suitable without having to do anything. The steps for determining the force (heat treatment, additive mixing, etc.) prior to pressure gI# are generally carried out in several continuous units or in units placed adjacent to each other. Na9,
The process becomes more iI specific.

Devices assembled from replaceable capital parts (e.g. according to GFR Reference No. 2730473) are known along with dances assembled from a few parts (FR Reference DLF No. 1944642). ing.

There are also known methods in which a double jacket is provided in the housing to control the temperature of the material inside. The objective is to create as many different types of compression parameters as possible and a variable range over a relatively wide range.

However, the basic drawback of these methods is their inefficient separation. This is primarily due to the constant dimensions of the hole in the capital part. As with W4, the perforated element acts in two different ways during its function. It holds a solid part and prevents the liquid part from flowing out by increasing its density. If the dimensions of the solid material (fiber) are much smaller than the dimensions of the hole, certain parts of it will penetrate the hole and stick to the wax, while other parts will fall through the hole, thereby causing separation. I! @ Lower the book. At the same time, the size of the hole is the adhesive fiber m
It gradually decreases from K. If the fibers are significantly larger than the hole, the arching resistance exerted across the hole increases. Of course, many other variations are possible between the two extreme cases described above, including the simultaneous occurrence of this extreme case.

Proper hole formation is further exacerbated by the fact that the layer of solid material in the vicinity of the hole exhibits a fundamentally different m-weave structure than the rest. This is due to the development of two extreme cases as well as periodic breakdowns. The configuration of the critical layer is basically determined by the hole size and distribution pattern. The filter gj is inversely proportional to the joint resistance of the solid material layer and the perforating member.

Thus, it is obvious that not only each function requires a different hole, but also that in an optimal case, even a single function requires holes of various sizes.

44 members with variable holes were already well known from early on [
This is introduced in Bi1%ken Specification No. 1000773 [In Specification 1, the drilling member is made up of sticks placed next to each other, and the gap between the sticks is 1 t, which is a ball or the like. It is set up with separate pieces like this. The fundamental drawback of this solution is that the magnitude of 11a[I can only be changed by disassembling the device 1. This partially limits the overall applicability of the device, since changing the dimensions of the hole requires a stoppage and a considerable amount of time t', and the process of a given technology can be reproduced in accordance with the changed conditions. Makes adjustment partially impossible.

The object of the present invention is to realize a method for adjusting the holes during operation, that is, changing the dimensions of the holes according to the material properties that vibrate during operation, thereby maintaining the filter effect at a constant value.

The device for solving the problem according to the invention is provided with a drive device and a housing with a worm shaft, a circular rock body and a perforated wall (in the device with a worm shaft also assembled from component parts).・One of the Uzing capitals is the hole 't' whose size can be changed during operation! and the hole is formed between at least two units movable with respect to each other, and at least one
The two units are connected to the DJ equipment. The jacket of the variable-sized housing is formed from two rolls that are rotatable within each other and provided with holes.

The rolls are formed from perforated or double-rowed jacket sectors. In some cases, it may be desirable to place the filter element between two rolls or inside a hole in the inner roll. It is formed by interlocking racks that can rotate around their axial edges. The jacket is formed with wedge-shaped rods that similarly fit into each other and are arranged in the generatrix direction so that they can move radially relative to each other.

According to yet another modification, a housing with four holes of variable size! The plain jacket consists of a rotating ring with radially arranged grooves.

The basic advantage of the solution according to the invention is that J! ! The object of the present invention is to make it possible to simultaneously change the parameters that mainly affect the amount of time, without having to stop the device or assemble it, due to changes in the degree of filter effectiveness during the transfer. By maximizing the area, the vW and dynamic separation of the components of the Ili weave are improved, and the chemical timeliness of the separated components is improved.

The device follows the brick-built frozen platform and Hakusong jI! From the nest, the worm shaft is erected and the worm shaft is compressed due to the properties of the braided fibers, from the element to the winding assembly, which ensures an optimal pressure distribution over the entire length of the worm shaft. The worm shaft rotates in a housing provided with an axial slot of variable dimensions aJ, the separation effect is influenced by dirt, and at the same time the worm shaft is driven via a stepless drive mtii'1, thus A-filling can be achieved during operation.

Details of non-invention! The following description will be made with reference to the attached drawings.

Figure i3N4 is a schematic diagram showing an example of an assembled device, and the drive device and machine stand are omitted. The assembled housing according to the bricklaying principle consists of a double-walled phosphorous-treated receiving funnel 2, a double-walled gutter unit 6, a double-walled control element part 8 and a hole of fixed dimensions. An element member 12 with a variable hole t, an element member 15 with a variable hole t, and a rotating chamber 1
1 and an exit throat 11 each time. The housing elements are held together by a hollow screw 16 and a gap 13. The screwing element is fixed to the machine stand with legs 7. The worm shaft is driven by a continuous drive via end journal bearings 5,19. 1# disposed in the outlet hole 11, the flexural support of the striking body is ensured by the hydraulic element member 10. A hole holder 1 arranged in the receiving funnel 2 allows the liquid addition mouth to flow in.

The inflow and outflow of the ramper medium into and out of the cable member in the double-walled ramper 4 is stump-shaped 83, 4, 9.

Guaranteed by 18. The flow of separated liquid components from the 1# element with fixed and variable holes is ensured by the stump-shaped portion 14.

Furthermore, certain Hakuzongu accumulators are provided with such stump-like sections, with the aid of which an optimal treatment medium is conveyed to the pressed material. Naturally, these elements are likewise provided with liquid-carrying stubs.

Figure 2 shows the housing Jj! shown in Figure 1! Some examples of configurations assembled from raw materials are shown, and the drive device and mechanical stand are omitted.

FIG. 3 shows two embodiments of a wormshaft assembled from JiI stack members arranged in a housing element with a pitch rhJ that varies from turn to turn. A screen feeder 20 with a threadless form element 21 ensures the feeding of the material in the first housing element. The housing 44 is held together by the spacing piece 13 and carries the worm shaft on the bearing. The length rLJt varies depending on the characteristics of the material to be squeezed.
The worm axis JI of the rhJ that changes with the help of the threadless form element member 21 that IV! A shaft is assembled from the nest member 22. A piece 13 that separates from the mixing blade element member 23
In addition to holding the housing elements together and carrying the shaft on various bearings, it also ensures the mixing of materials. The worm shaft elements 22 are releasably connected to each other, as shown in FIG. 4, for example. The retention and radial alignment of the shaft is ensured by the housing element.

The worm shaft is rotated by an electric motor (not shown) via a continuously variable speed drive device and/or a reduction gear.

FIG. 5 shows the actual connection of the housing elements. Figures 6 and 7 as well as Figures 88 and 9 show practical examples of type 2d1 housings with variable size axial slots. According to one practical solution, the variable hole is formed by racks 24 and 25 that can be rotated around an axis,
The engagement between the teeth, a plan view of which is shown in FIG. 7, provides a slot in the housing whose size changes with the number of turns of the rack. According to another possible solution, the housings can rotate relative to each other and the inner rolls 26
and an outer roll 2T, each roll is provided with a large hole, and FIG. 8 is a plan view thereof, and FIG. 9 is a cross-sectional view thereof. Four holes of variable size are provided by covering the holes, which can be varied by rotation of the roll.

10 and 11 show other embodiments of mutually rotatable rolls. In this case, 1l--
The roll 26 and the outer roll 2T are composed of jacket flat pieces 28 and 29, respectively. The sectors 28.28 oriented towards the generatrix are each fixed to a ring 30.31. #l hole size is inner roll 26 and outer 4a-roll 274
'Can be changed by rotating them relative to each other.

To improve filter effectiveness, porous filter media 32 can be placed in the slots of inner roll 26, as shown in FIG. When the filter media 32 is saturated, the inner roll 26 and the outer roll 21 are brought into a covered position and the filter media 32 is saturated.
Y: Exchange.

Yet another method of improving filter effectiveness is shown in FIG. 13, in which the filter media 32
is placed between the inner roll 26 and the outer 1141+2- roll 21. In this case, it is desirable that the medium be fiber-free.

FIGS. 14 and 15 show a housing element formed by wedge-shaped split plates 33, 34 that are radially movable with respect to each other. The size of the holes can be changed at will by moving these plate pieces 34 in the radial direction.

5g By the method shown in FIG. 16 and FIG. Different hole sizes can be created by varying the size of the holes.During operation, large variations can be achieved by relaxing the axial compression.

An arbitrary number of all-Ill-hole elements can be arranged consecutively, and holes that are most suitable for the properties of the material can be set within each element. Due to its flow properties, the material is conveyed and forced into the assembly by a removably connected worm shaft.

Using various surface configurations of variable holes, such as cylindrical surfaces, flat surfaces, pentagrams, etc., the most significant results are obtained in the case of two-phase systems.

According to old judgments, the most powerful device is provided by slots (axial slots in the case of rolls). The configuration (distribution) of these slots is based on operational dimensions.

The device according to this invention works as follows.

The device is assembled from the housing and the worm element by assembling together a sufficient number of perforated heating elements according to processing technology requirements.

The material to be separated (solid/liquid system) t-receiver is sent to the receiving funnel. Having a certain amount of material in the funnel will ensure that the worm is at the correct level.

(In the case of arcuate materials, a mixer can be placed inside the funnel.) Separate! The two-phase material is fed between the windings of the worm, and phase separation begins due to the narrowing of the cross section in the direction of development. This narrow volumetric space can be increased by reducing the joint or by increasing the cross section of the worm shaft, or by a combination of both. The worm shaft is assembled according to the flow characteristics of the system to be separated. The part of the separated liquid phase (the part that was separated during pretreatment) flows out through the jacket of the housing provided with certain holes, while the other The portions are delivered onto a surface provided with variable size slots. The effluent liquid component contains only a minimal amount of solids, either total heat or heat. This condition is the ail of the groove during operation! IK
The impact cone placed at the end of the outlet is used to increase the pressure of the press, which closes the passage of the solid phase in a similar manner.

Changes in the slot size and adjustment of the impact cone are carried out by a common hydraulic system or, in the case of small installations, by a mechanical system.

In the separation process, the required pressing temperature can be adjusted with the help of a temperable housing 4iI layer,
This aspect comes with a number of processing technology advantages.

As is clear from the above, the device according to the invention makes it possible to carry out all the functions of determining the complete ml of tissue fluid with a simple device in such a way that the necessary parameters can be varied within a wide range. The consumption and nutritional values of the separated components can be maintained at arbitrary values and the desired properties of all components can be achieved.

In the modular screw press described with the schematic diagram, the resistance to through flow can be maintained at a constant value, making it possible to guarantee a constant purity of the separated tissue fluid through the holes of variable size in relation to the varying parameters. Become. This advantage can also be applied to many other areas of filter technology.
