Abstract
Description
Technical Field
[0001] The utility model relates to a device for capturing and removing particles, in particular, the device for capturing and removing particles is to be inserted into a domestic or industrial heating / air conditioning system to avoid unstable or ineffective operation of the system itself. Background Art
[0002] Devices for capturing and removing particles are usually introduced into heating / air conditioning systems inside which a heat transfer fluid circulates, in order to limit the deposits of these particles in various points of the system, thus causing unstable operation and inefficient operation thereof. In particular, the excessive presence of such particles can have several adverse effects on the operation of the system, for example associated with unstable valve operation, lower production of the exhaust system, deposits in the supply lines, blockages or clogging in the pumps, accumulation of magnetite inside the magnetic rotors and lower production of the heat exchangers.
[0003] Due to energy-related problems, there is also a need for heat transfer fluids with a high degree of cleanliness. In fact, attempts are being made to achieve increasingly efficient heating / air conditioning systems that make it possible to use smaller quantities of heat transfer fluids in order to consume smaller quantities of thermal energy. For this purpose, systems have been installed that are provided with the use of pipes and valves with increasingly smaller dimensions, requiring heat transfer fluids that are sufficiently free of dirt particles in order to avoid the above-mentioned adverse effects on the operation of the system.
[0004] The size and nature of the above-mentioned suspended particles in the heat transfer fluid circulating in the system can be of various types. For example, in the heat transfer fluid, there may be suspended mud particles, sand or iron residues with a size ranging from a few millimeters to a few centimeters.
[0005] For the rough removal of dirt particles, dirt separators can be used using the principle of decantation. Thus, at a certain point in the circuit, the heat transfer fluid circulating in the system is suddenly slowed down and the dirt particles fall downwards by gravity in a quiet area and are removed through a suitable drain. In this case, the efficiency of the removal of the particles depends on the degree to which the heat transfer fluid is slowed down if compared with the standard speed of the fluid moving inside the system.
[0006] Removal of dirt particles can also be achieved by intercepting them with a fine mesh filter. Thus, the removal of particles will be highly efficient, since the mesh filter will intercept all particles whose size is larger than the size of the holes in the mesh (e.g., hundreds of microns). However, removal of particles by simple filtration will be rather complicated, since the mesh filter will become clogged very quickly and will require frequent maintenance to keep it clean and enable the system to work efficiently and optimally.
[0007] In the heat transfer fluid, there are also some very small particles of ferromagnetic material in the micrometer range suspended. These ferromagnetic residues are not removed by simply utilizing the decantation principle, nor are they captured by mesh filters. However, despite their small size, these particles settle in the tubes when the heating system is turned off during the summer period, forming a layer of ferromagnetic residual material. When the heating system is turned on again, the accumulated layer of ferromagnetic residual material detaches in the form of macroscopic fragments, which facilitates the operation of an unstable system. Therefore, in order to remove these ferromagnetic material particles, magnetic attraction must be used.
[0008] The different nature and size of the particles then require different filtration steps in order to significantly reduce the concentration of such particles in the heat transfer fluid circulating inside the system.
[0009] There are devices on the market for capturing and removing particles that provide the above three particle capture steps depending on the size and nature of the particles. However, the devices available on the market have some disadvantages as follows:
[0010] - Complex and massive structures;
[0011] - the difficulty of adjusting the location of the equipment depending on whether the heating / air conditioning system has horizontally or vertically arranged pipes;
[0012] - the difficulty of carrying out the cleaning and maintenance phases of the equipment;
[0013] -Requires shutting down the heating / air conditioning system and completely removing the equipment to remove trapped particles, increasing system downtime;
[0014] - Filtration systems are characterized by a very low flow rate coefficient Kv and high load losses when the filter is dirty. Utility Model Content

[0031] Figure 1 The device for capturing and removing particles, generally referred to as 10, shown in Fig. 1 is suitable for installation in a pipe connected to a heating / air conditioning system in which a heat transfer fluid circulates.
[0032] The device 10 allows the capture of dirt particles suspended in the heat transfer fluid circulating inside the system and also allows their removal from the device through a suitable drain valve placed in the lower part of the device. Such particles may be of different natures and sizes and, if not removed, may be deposited at different points of the system, causing unstable or ineffective operation of the system itself.
[0033] The device 10 comprises a body 11 which may have a cylindrical shape. An inlet 12 and an outlet 13 are obtained on the body 11, which are used for the inlet and outlet, respectively, of a heat transfer fluid circulating in a system to which the device 10 is connected. The inlet 12 and the outlet 13 are made circular on the side wall of the cylindrical body 11. More specifically, the inlet 12 has a circular cross section and the outlet 13 has an annular cross section, and the inlet 12 and the outlet 13 are made coaxially.
[0034] Inside the body 11 a main chamber 14 is obtained which defines the path of the heat transfer fluid between the inlet 12 and the outlet 13 .
[0035] At the lower end 30a, the body 11 has a thread 32 for screwing into a lower body 33, which seals the body 11 at the bottom. Between the body 11 and the lower body 33, a collecting chamber 24 is obtained inside, which is used to collect dirt particles captured by the device 10. The collecting chamber 24 is arranged below the main chamber 14.
[0036] The lower body 33 has a bottom surface 43 inclined relative to the horizontal direction. Therefore, the collecting chamber 24 has a triangular cross section, an approximately right-angled triangular cross section, which can be Figure 4 , Figure 5 The cross section of bottom surface 43 approximately identifies the hypotenuse of a right triangle.
[0037] On the bottom surface 43 of the lower body 33 a drain valve 22 is provided which can be opened manually for removing dirt particles suspended in the heat transfer fluid and captured by the device 10. The drain valve 22 is obtained in particular on the lower edge 44 of the lower body 33.
[0038] The lower body 33 has a central protrusion 34 obtained on the bottom surface 43. The central protrusion 34 protrudes centrally along the axis of the cylindrical body 11 inside the main chamber 14. The central protrusion 34 is made hollow and open at the bottom, and it is used to accommodate a support rod 35 therein. Said support rod 35 is used to support a series of magnets 16, in this particular case three magnets 16, for magnetically attracting ferromagnetic dirt particles suspended in the heat transfer fluid circulating in the system to which the device 10 is connected. The magnets 16 are mounted on removable rods 35, which are arranged along the central axis of the main chamber 14 of the body 11. In particular, the magnets 16 generate a magnetic field in the surrounding area, more precisely in the main chamber 14 in which the heat transfer fluid circulates; the ferromagnetic particles suspended in the heat transfer fluid are affected by the magnetic field and settle in the outer wall of the central protrusion 34.
[0039] The magnet 16 supported by the support rod 35 is shaped as a ring.
[0040] The support rod 35 may be inserted into or extracted from the lower opening of the central protrusion 34 according to operational requirements, as will be apparent from the following description.
[0041] The device 10 is also provided inside the main chamber 14 with an interception and separation element 15 for dirt particles suspended in the heat transfer fluid.
[0042] The interception and separation element 15 comprises a plurality of mesh walls 21 having an approximately rectangular shape snap-fitted to a circular section body 23 of the interception and separation unit 15 .
[0043] The mesh wall 21 is snap-fitted to the central body 23 via the longer sides of the rectangle. Figure 2 or Figure 6 As can be seen in the cross-sectional view of , in each snap-fit point, the mesh wall 21 is guided according to a direction substantially tangential to the circular cross-section central body 23 .
[0044] The plurality of mesh walls 21 are used to intercept and separate, by decantation, dirt particles present in the heat transfer fluid circulating in the system.
[0045] The central body 23 of the interception and separation element 15 is hollow and fits onto the central protuberance 34 .
[0046] In the upper part of the central body 23 of the intercepting and separating element 15 a second thread 41 , annular grooves 42 and a system 52 of peripheral teeth are obtained.
[0047] like Figure 3 As shown, a locking clip 40 is provided to lock the intercepting and separating element 15 to the body 11 of the device 10. The locking clip 40 has an open ring shape and has a plurality of transverse cutouts to facilitate the insertion of the locking clip 40 into the annular groove 42 in order to lock the intercepting and separating element 15 to the body 11, so that the intercepting and separating element 15 can be rotated about its own axis in any case.
[0048] A mesh filter 17 is also inserted inside the main chamber 14 of the body 11 of the device 10. The mesh filter 17 has a bearing structure made of a cylindrical rigid plastic material. On the bearing structure of the mesh filter 17, an inlet hole 29 for the heat transfer fluid entering the main chamber 14 is obtained. The inlet hole 29 of the mesh filter 17 is circular and is arranged at the inlet 12 of the body 11. More specifically, the diameter of the inlet hole 29 of the mesh filter 17 is substantially the same as the diameter of the inlet 12 of the body 11.
[0049] The mesh filter 17 is provided with a plurality of mesh portions 19 and a non-porous continuous portion 20, the mesh portions 19 being used to mechanically retain dirt particles present in the heat transfer fluid circulating in the system.
[0050] The mesh 19 of the mesh filter 17 is provided with very small pores, for example in the order of one hundred microns. For example, considering a mesh filter 17 having a mesh 19 provided with pores of 150 microns, the mesh filter 17 is able to capture particles larger than 150 microns. More precisely, particles smaller than 150 microns but comparable to this value (e.g. of the same order) have a high probability of intercepting the weft yarns of the mesh 19 of the mesh filter 17, thereby remaining captured and reducing the actual size of the individual pores. Therefore, over time, the probability that the mesh filter 17 is also able to intercept particles smaller than the size of the pores (according to the present embodiment, smaller than 150 microns) increases.
[0051] The mesh filter 17, the interception and separation element 15 and the central protrusion 34 containing a series of magnets 16 have cylindrical symmetry and are coaxially arranged inside the main chamber 14 in the order described in this paragraph from the outermost to the innermost.
[0052] An interception and separation element 15 , a magnet 16 and a mesh filter 17 are arranged in series in the path of the heat transfer fluid between the inlet 12 and the outlet 13 inside the body 11 of the device 10 .
[0053] The device 10 is also provided with a removable brush 18 inside the body 11 for removing dirt particles mechanically retained by the mesh filter 17 .
[0054] In particular, the movable brush 18 can be actuated from the outside to allow dirt particles mechanically retained by the mesh filter 17 to fall into the collection chamber 24 by gravity. More precisely, the movable brush 18 can be rotated from the outside. Fig. 7A , Figure 7B As shown, the movable brush 18 is tilted to allow dirt particles mechanically held by the mesh filter 17 to fall into the collection chamber by gravity only when rotating clockwise. For example, the movable brush 18 can be tilted 45° relative to the horizontal direction, with this direction to drag the dirt particles downward.
[0055] The movable brush is arranged in a portion between the two mesh walls 21 of the intercepting and separating element 15 .
[0056] The rotation of the movable brush 18 from the outside is achieved by a rotatable knob 27 arranged above the body 11 of the device 10. In particular, the rotatable knob 27 rotates integrally with the interception and separation element 15 on which the movable brush 18 is arranged. The interception and separation element 15 is in fact hooked to the above-mentioned rotatable knob 27 by a system 52 of peripheral teeth.
[0057] A spatula 45 projects below the movable brush 18. This spatula 45 is a harmonic steel blade that can be rotated integrally with the movable brush 18 from the outside by a rotatable knob 27. When rotated clockwise, the spatula 45 serves to scrape the bottom of the collection chamber 24 to convey particles accumulated on the bottom of the above-mentioned collection chamber 24 toward the discharge valve 22.
[0058] The rotatable knob 27 can only be rotated clockwise to allow dirt particles mechanically retained by the mesh filter 17 to fall into the collection chamber 24 by gravity. Fig.10 , Fig.11 As shown, there may be an arrow in the rotatable knob 27 to indicate to the user the direction of rotation of the knob itself.
[0059] The rotatable knob 27 has inner ribs 59 .
[0060] The cam 25 is interposed between the rotatable knob 27 and the body 11 of the device 10. More precisely, the cam 25 is snap-fitted on the upper end 30b of the body 11. The cam 25 has a wing 39 which projects vertically above the cam 25 and defines the rest position of the movable brush 18. The cam 25 also has four circumferential fins 60, each of which has a free end 58 shaped to contact each inner rib 59 of the rotatable knob 27. In particular, the contact between each free end 58 and each inner rib 59 enables the rotatable knob 27 to rotate clockwise and prevents the rotatable knob 27 from rotating counterclockwise, i.e. rotating in a direction of rotation opposite to the direction of rotation that enables the dirt particles retained by the mesh filter 17 to fall into the collection chamber 24 by gravity.
[0061] Furthermore, the rotatable knob 27 has a first outer rib 61 . The body 11 has a second outer fin 62 .
[0062] The rotatable knob 27 has a first central hole 26 for receiving a plug 36, which can be removed if an additive is required to be added to the heat transfer fluid circulating in the system. The central hole 26 can be, for example, a circular hole. The plug 36 is screwed onto the central body 23 of the interception and separation element 15 by a second thread 41.
[0063] The plug 36 in turn has a second central hole 37 which is closed by a bleed screw 38. If it is necessary to bleed air from the body 11 of the device 10, the screw 38 can be removed.
[0064] As mentioned above, especially in Figure 3 and Figure 6 As can be seen in FIG. 1 , the mesh filter 17 has a continuation 20 . At such a continuation 20 , the mesh filter 17 has at least one recess 28 for accommodating the movable brush 18 when it is not used to remove dirt particles mechanically held by the mesh filter 17 .
[0065] Then, the mesh filter 17 is shaped so that the movable brush contacts the mesh portion 19 when the movable brush is rotationally actuated clockwise from the outside for removing dirt particles held by the mesh filter 17. The mesh filter 17 is also shaped so that the movable brush does not contact the continuous portion 20 at the recess 28.
[0066] The position of the movable brush 18 at the recess 28 (previously referred to as the rest position of the movable brush 18) can also be recognized from the outside as corresponding to a configuration in which the position of the first outer rib 61 matches the position of the second outer rib 62. Therefore, if the ribs 61 and 62 are aligned, the first outer rib 61 and the second outer rib 62 indicate to the user the rest position of the movable brush 18. Alternatively, when the first outer rib 61 and the second outer rib 62 are not aligned, they allow the user to understand that the movable brush 18 is in contact with the mesh portion 19 of the mesh filter 17 to allow the dirt particles mechanically held by the mesh filter 17 to be removed.
[0067] The size of the device 10 varies depending on the flow rate of the heat transfer fluid supported by the system. In particular, if the flow rate is low, the size of the device 10 will be smaller; vice versa, if the flow rate is higher, the size of the device 10 will be larger.
[0068] The device 10 is connected to a T-shaped element 50 upstream of the inlet 12 and downstream of the outlet 13. The element 50 is used to deliver the heat transfer fluid from the system to the inlet 12 of the device 10 for the dirt particle capture and removal operation. At the same time, the element 50 is used to deliver the heat transfer fluid from the outlet 13 of the device 10 to the system after the dirt particle capture and removal operation.
[0069] The device 10 is provided with a third thread 46 for sealingly connecting to a component 50 via a connection end 49 .
[0070] like Figure 1 As shown, element 50 has an inlet passage 47 that allows heat transfer fluid to enter device 10 through inlet 12. Element 50 also has an outlet passage 48 that allows heat transfer fluid to exit device 10 through outlet 13. Inlet passage 47 and outlet passage 48 are not in communication with each other.
[0071] The cross-section of the inlet passage 47 of the element 50 at the connection end 49 is dimensioned to match the inlet 12 of the device 10. The cross-section of the outlet passage of the element 50 at the connection end 49 is dimensioned to match the outlet 13 of the device 10.
[0072] The size of the element 50, and thus the device 10, is determined according to the flow rate of the heat transfer fluid supported by the system. In particular, if the flow rate is low, the size of the element 50 will be smaller; vice versa, if the flow rate is higher, the size of the element 50 will be larger.
[0073] The element 50 also serves to fractionate the flow. The element 50 actually has a flow diverter 51. The flow diverter 51 has a cylindrical shape and can be rotated from the outside. The flow diverter 51 is shaped to divert the flow of the heat transfer fluid into the device 10 through the inlet channel 47 of the element 50. In particular, the flow diverter 51 adjusts the flow rate of the heat transfer fluid inside the device 10 based on its angular position so that only a certain percentage of the flow rate of the heat transfer fluid circulating in the system can enter the device 10. For example, the flow diverter 51 allows 40% of the flow rate of the heat transfer fluid to enter the device 10; the flow diverter 51 also allows the remaining 60% of the flow rate of the heat transfer fluid to flow directly into the outlet channel 48 without temporarily undergoing the dirt particle capture and removal step.
[0074] The main function of the flow splitter 51 is to obtain a high flow rate coefficient value Kv and at the same time reduce the energy consumption required to allow the heat transfer fluid to circulate in the system. For example, during a first step of circuit opening, the entire flow rate of the heat transfer fluid flows into the device 10, leaving the flow splitter 51 in a non-operating configuration so as to submit the entire flow rate of the heat transfer fluid to the three filtering steps. Then, in order to reduce the system energy consumption, the flow splitter 51 is set in an operating configuration so that only a part of the heat transfer fluid is submitted to the three filtering steps, for example with the above-mentioned percentages.
[0075] The flow diverter 51 of the element 50 can also be used to regulate the flow rate of the heat transfer fluid, in particular in cases where the flow rate of the heat transfer fluid circulating in the system is so high that decantation is almost ineffective due to the high-speed movement of the fluid. In addition, if the flow rate of the heat transfer fluid is too high, the mesh filter 17 will also be blocked very quickly, making it necessary to clean it immediately and continuously by rotating the movable brush 18. In order to make the process of capturing and removing dirt particles inside the device 10 last longer, it is therefore necessary to reduce the flow rate of the heat transfer fluid entering the device 10, so that the heat transfer fluid is submitted to the step of capturing and removing dirt particles little by little. Therefore, in order to circulate a sufficiently clean heat transfer fluid inside the system to avoid unstable operation of the above-mentioned system, it is necessary to circulate the heat transfer fluid through the system several times, so that after a variable number of cycles, the entire flow rate of the fluid has undergone the step of capturing and removing dirt particles inside the device 10.
[0076] The operation of the device 10 connected to the element 50 will now be described in detail.
[0077] The heat transfer fluid circulating in the system with a given amount of dirt particles enters the element 50 and is conveyed through the inlet channel 47 towards the inlet 12 of the device 10. Inside the device 10, the heat transfer fluid is connected in series with the interception and separation element 15, the magnet 16 and the mesh filter 17. Then, in sequence, the heat transfer fluid is submitted to a decantation process, which causes a reduction in the fluid velocity and causes the dirt particles to fall downward by gravity; the ferromagnetic particles suspended in the heat transfer fluid are affected by the magnetic field generated by the magnet 16, so that such ferromagnetic particles are constrained on the wall of the central protrusion 34; the heat transfer fluid is filtered by the mesh 19 of the mesh filter 17 for removing dirt particles of a size larger than the pores of the mesh filter 17, as described above; finally, the heat transfer fluid leaves the outlet 13 of the device 10 and flows through the outlet channel 48 of the element 50 to be reintroduced into the system, wherein the amount of dirt particles is less than the initial amount of dirt particles.
[0078] The dirt particles separated by decantation immediately settle on the bottom at the bottom surface 43 of the collection chamber 24. After a period of time from the heat transfer fluid passing through the inside of the device 10, a large amount of ferromagnetic particles will be deposited on the wall of the central protrusion 34, and a large amount of dirt particles will be deposited in the mesh portion of the mesh filter 17.
[0079] The support rod 35 supporting the magnet 16 is removed from the central protrusion 34, and the ferromagnetic particles deposited on the wall of the central protrusion 34 are no longer affected by the magnetic attraction that constrains them to the aforementioned wall, so that they fall by gravity and are also deposited on the bottom surface 43 of the collection chamber 24.
[0080] In order to remove the dirt particles mechanically held on the mesh 19 of the mesh filter 17, the movable brush 18 is rotated from the outside by the rotatable knob 27. The above-mentioned structural shape of the movable brush 18 is such that once it is rotated clockwise, the dirt particles mechanically held on the mesh 19 of the mesh filter 17 can fall by gravity and be deposited on the bottom surface 43 of the collection chamber 24.
[0081] The rotation of the movable brush 18 is also integral with the rotation of the spatula 45 , which acts on the particles deposited on the bottom surface 43 of the collection chamber 24 , pushing them towards the discharge valve 22 .
[0082] Opening of the drain valve 22 allows the outflow and removal of dirt particles captured by the apparatus 10 .
[0083] One advantage of the device 10 according to the invention is its compact and non-bulky structure, which makes it possible to carry out three fluid filtering steps in one and the same body.
[0084] Another advantage is that by means of the device 10 connected to the element 50, the position of the device 10 can be easily adapted to pipes arranged horizontally or vertically.
[0085] Yet another advantage is that cleaning and maintenance steps of the device 10 can be easily performed, in particular dirt particles can be removed without disassembling the device 10. Disassembling the device 10 for the necessary cleaning and maintenance of the device 10 would involve inserting a shut-off valve for closing the system. This would make the system more complex and expensive, while also increasing the downtime of the system.
[0086] In an alternative embodiment, the support rod 35 may support only one magnet 16 .
[0087] In another alternative embodiment, the movable brush 18 can have an inclination rotated by 90° compared to the configuration shown in the drawings. In this case, by rotating the movable brush 18 counterclockwise by the rotatable knob 27, the removal and descent of the dirt particles mechanically captured by the mesh filter 17 towards the collection chamber 24 by gravity can also be obtained.
[0088] Variations on the configuration of the above-described components shown in the drawings are possible.
