DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] See also Figure 1 , showing a structural diagram of a three-way distributor of the related art.

[0030] like Figure 1As shown, a flap is provided inside the three-way distributor in the related art, and the flap is connected to the rotating shaft below the three-way distributor, and the rotating shaft can drive the flap to rotate to achieve the blocking or connection of the left or right material passage. However, it can be seen from the figure that since the lower end of the flap is connected to the rotating shaft below the three-way distributor, after the material enters the material passage from the feed inlet, it will inevitably pass through the lower end of the flap and the rotating shaft. Since there is an angle between the lower end of the flap and the rotating shaft, and there is an angle between the flap or the rotating shaft and the distributor itself, and since the angle opens upward, it is easy for the material to accumulate at the angle position, thereby affecting the smoothness of the material passing.

[0031] Therefore, the three-way distributor in the related technology has at least the following problems: the flap and the rotating shaft occupy the channel of the main material flow, resulting in blocked material flow in the internal space of the three-way distributor; at the same time, the flap and the flap shaft are directly washed and worn by the material flow, thus affecting the service life of the flap and the rotating shaft; in addition, if the accumulated material at the angle formed between the flap or the rotating shaft and the three-way distributor falls off, part of the temporarily stored material of the last transport will be superimposed on the material to be transported next time during the material conversion, resulting in a mixing accident; in addition, the accumulated material on the flap and the rotating shaft may cause the flap to not close tightly, thus causing a material leakage accident.

[0032] Based on the above, an embodiment of the present application provides a three-way distributor to solve the above problems at least to a certain extent, reduce the possibility of material accumulation in the three-way distributor, improve the smoothness of material flow in the three-way distributor body, and improve the working efficiency of the equipment.

[0033] See also Figure 2 , shows a structural diagram of a three-way distributor according to an embodiment of the present application.

[0034] It should be noted that Figure 2 What is shown is a front view or a rear view of a three-way distributor, but because structures such as a flap are arranged inside the three-way distributor, the internal structure of the three-way distributor is shown with dotted lines to facilitate a more comprehensive understanding of the present application.

[0035] According to one aspect of an embodiment of the present application, a three-way distributor is provided, comprising:

[0036] A distributor body 1, wherein the distributor body 1 is provided with a feed port 11 and two discharge ports 12, each of the discharge ports 12 is connected to the feed port 11 to form a discharge channel 13;

[0037] Two flaps 2, each flap 2 is movably connected to the top of a side wall 14 of the discharge channel 13;

[0038] Two driving mechanisms 3, each of which is connected to one of the flaps 2, are used to drive the corresponding flap 2 to rotate around the top of the corresponding side wall 14 of the discharge channel 13, so that the flap 2 blocks the discharge channel 13, or connects the discharge channel 13, wherein when the discharge channel 13 is connected, the flap 2 corresponding to the discharge channel 13 is attached to the side wall 14 of the discharge channel 13.

[0039] The working principle of the three-way distributor of the embodiment of the present application is described below:

[0040] It is understandable that the material switching transportation of the three-way distributor can be realized by sending a control command to the three-way distributor by the control terminal. Specifically, when the material transportation needs to switch the transportation direction, the control terminal sends a control command to the three-way distributor. After the three-way distributor is powered, the two driving mechanisms 3 drive the two flaps 2 to rotate around the upper side walls 14 of the corresponding discharge channel 13 in the same direction, so that the material can be transported in the same direction. Figure 2 It can be seen that the two flaps 2 and the two driving mechanisms 3 are symmetrically arranged on both sides of the three-way distributor. When the two driving mechanisms 3 drive the two flaps 2 to rotate around the upper side wall 14 of the corresponding discharge channel 13 in the same direction, one of the flaps 2 blocks the corresponding discharge channel 13, and the other flap 2 connects the corresponding discharge channel 13. For example: the left driving mechanism 3 pulls the left flap 2 to rotate around the upper side wall 14 of the left discharge channel 13, so that the left discharge channel 13 is connected; the right driving mechanism 3 pulls the right flap 2 to rotate around the upper side wall 14 of the right discharge channel 13, so that the right discharge channel 13 is blocked, so that the material passes through the left discharge channel 13 and flows out from the left discharge port 12.

[0041] Based on the above disclosed content, since the flap 2 is movably connected to the top of the side wall 14 of the discharge channel 13, the angle between the flap 2 and the top of the side wall 14 of the discharge channel 13 opens downward, and when the discharge channel 13 is connected, the flap 2 fits against the side wall 14 of the discharge channel 13. At this time, the flap 2 is equivalent to the side wall 14 of the discharge channel 13, and the inside of the discharge channel 13 is hollow, so there is no area where material accumulation can be formed, thereby reducing the possibility of material accumulation in the three-way distributor, improving the smoothness of material flow of the three-way distributor body 1, and improving the working efficiency of the equipment; in addition, when the flap 2 serves as the side wall 14 of the discharge channel 13, it can reduce the impact of the flap 2 being directly eroded and worn by the material flow, thereby increasing the service life of the flap 2; in addition, since no material accumulation is formed, it will not cause mixing accidents or leakage accidents.

[0042] In some embodiments, a rotating shaft 4 is provided above the side wall 14 of the discharge channel 13, and a flap 2 is sleeved on the rotating shaft 4; a rotating shaft seat 41 is respectively provided on the front outer wall and the rear outer wall of the distributor body 1, and each of the rotating shaft seats 41 is hinged to one end of the rotating shaft 4, and a limit switch 42 is provided at a preset position of the rotating shaft seat 41.

[0043] It should be noted that by arranging the rotating shaft 4 above the side wall 14 of the discharge channel 13, a flap 2 is sleeved on the rotating shaft 4, so that the angle between the rotating shaft 4 and the flap 2 opens downward, and the angle between the rotating shaft 4 and the upper side wall 14 of the discharge channel 13 opens downward, then when the material passes through the discharge channel 13, no material accumulation will form at the angle position, thereby improving the smoothness of the material flow of the three-way distributor body 1 and improving the working efficiency of the equipment. In addition, since the rotating shaft 4 is arranged above the side wall 14, the impact of the rotating shaft 4 being directly eroded and worn by the material flow can be reduced, thereby increasing the service life of the rotating shaft 4.

[0044] It is understandable that arranging the rotating shaft seat 41 on the front outer wall and the rear outer wall can ensure the rotation of the flap 2 without affecting the internal material flow of the discharge channel 13 .

[0045] It can be understood that, since each end of the rotating shaft 4 is hinged to a rotating shaft seat 41 , the rotating shaft 4 can rotate along the rotating shaft seat 41 , thereby realizing the rotation of the flap 2 .

[0046] It can be understood that each shaft seat 41 is provided with two limit switches 42, one limit switch 42 is used to limit the starting position of the shaft 4, and the other limit switch 42 is used to limit the terminal position of the shaft 4. Since the rotating shaft 4 is sleeved with the flap 2, the rotating shaft 4 and the flap 2 rotate synchronously, so the limit switch 42 is adapted to the rotation angle of the flap 2 at the preset position of the shaft seat 41. Specifically, when the flap 2 rotates to fit the side wall 14 of the discharge channel 13, one of the limit switches 42 is used to limit the position, and when the flap 2 rotates to block the discharge channel 13, the other limit switch 42 is used to limit the position.

[0047] See also Figure 4 , showing a structural diagram of another three-way liquid distributor according to an embodiment of the present application.

[0048] In some embodiments, a hinge arm 43 is provided between the rotating shaft seat 41 and the front outer wall or the rear outer wall, one end of the hinge arm 43 is sleeved on the rotating shaft 4 , and the other end of the hinge arm 43 is connected to the driving mechanism 3 .

[0049] It should be noted that, when in use, the hinged arm 43 drives the rotating shaft 4 to rotate under the drive mechanism 3, thereby driving the flap 2 to rotate. It can be understood that, since the hinged arm 43 is arranged between the rotating shaft seat 41 and the front outer wall or the rear outer wall, that is, arranged outside the distributor body 1, it can ensure the rotation of the flap 2 without affecting the internal material flow of the discharge channel 13.

[0050] See also Figure 3 , showing Figure 2 A partial enlarged view of point A in the middle.

[0051] In some embodiments, a hinge seat 21 is provided on a side of the flap 2 facing the corresponding side wall 14 of the discharge channel 13 , and the driving mechanism 3 corresponding to the flap 2 passes through the side wall 14 of the discharge channel 13 and is connected to the hinge seat 21 .

[0052] It can be understood that by directly connecting the driving mechanism 3 with the flap 2, the driving force of the driving mechanism 3 directly acts on the flap 2, that is, directly pushing or pulling the flap 2 to rotate, and then driving the rotating shaft 4 to move, thereby simplifying the force composition of the rotating shaft 4, and the rotating shaft 4 is arranged above the side wall 14 of the discharge channel 13, which can avoid the increase of resistance during the movement of the rotating shaft 4 after the material sticks, improve the working conditions of the rotating shaft 4, and avoid the frequent occurrence of weld cracks and broken shaft failures.

[0053] In some embodiments, the driving mechanism 3 includes a hydraulic push rod 31 and a hydraulic cylinder 32 , one end of the hydraulic push rod 31 is connected to the hydraulic cylinder 32 , and the other end of the hydraulic push rod 31 is provided with a hydraulic telescopic head 311 , and the hydraulic telescopic head 311 is hinged to the articulated seat 21 .

[0054] It should be noted that when the driving mechanism 3 includes a hydraulic push rod 31 and a hydraulic cylinder 32, the three-way distributor is an electro-hydraulic three-way distributor. Then, when the hydraulic push rod 31 is supplied with oil by the hydraulic cylinder 32, the hydraulic telescopic head 311 extends forward to push the flap 2 to rotate to block the discharge channel 13. On the contrary, when the hydraulic push rod 31 is supplied with oil by the hydraulic cylinder 32, the hydraulic telescopic head 311 retracts backward to pull the flap 2 to connect the discharge channel 13.

[0055] It should be noted that the hydraulic push rod 31 and the hydraulic cylinder 32 can be arranged as an integral whole, in which case the hydraulic push rod 31 and the hydraulic cylinder 32 are directly connected; the hydraulic push rod 31 and the hydraulic cylinder 32 can also be arranged separately, in which case the hydraulic push rod 31 and the hydraulic rod can be connected through an intermediate piece, for example, the driving mechanism 3 also includes an oil pipe 33, and one end of the hydraulic push rod 31 is connected to the hydraulic cylinder 32 through the oil pipe 33.

[0056] It can be understood that each hydraulic push rod 31 is connected to the hydraulic cylinder 32 via two oil pipes 33 , one of the oil pipes 33 is used as an oil supply pipe 33 , and the other oil pipe 33 is used as an oil return pipe 33 .

[0057] It can be understood that when the hydraulic push rod 31 is connected to the hydraulic cylinder 32 through the oil pipe 33, the installation position of the hydraulic cylinder 32 can be adjusted according to the actual application scenario of the three-way liquid distributor. For example, the hydraulic cylinder 32 can be removably arranged on the outer wall of the distributor body 1, thereby reducing the space requirements on the equipment site and improving the flexibility of the equipment.

[0058] In some embodiments, an alloy lining plate (not shown) is provided on a side of the side wall 14 of the discharge channel 13 facing the corresponding flap 2, and the wear resistance value of the alloy lining plate is greater than or equal to a wear resistance threshold value.

[0059] It can be understood that since the corresponding flap 2 is attached to the side wall 14 of the discharge channel 13 when the discharge channel 13 is connected, the side wall 14 of the discharge channel 13 will frequently contact the back of the flap 2 during the material reversing transportation. Therefore, in order to increase the service life of the side wall 14, an alloy lining is provided on the side of the side wall 14 of the material channel facing the corresponding flap 2, thereby increasing the service life of the side wall 14.

[0060] In addition, alloy linings may also be provided in various areas of the inner wall of the distributor body 1 that are susceptible to impact by materials, such as the intersection of two discharge channels 13 below the distributor body 1, to increase the overall service life of the separator body.

[0061] In some embodiments, a first length of the side wall 14 of the discharge channel 13 is greater than or equal to a corresponding second length of the flap 2 .

[0062] It can be understood that the length of the flap 2 should be the same as the opposite side of the side wall 14 of the discharge channel 13, so that the discharge channel 13 can be tightly sealed to avoid leakage, and the side wall 14 of the discharge channel 13 can be greater than the length of the flap 2, or equal to the length of the flap 2, so that at least the flap 2 can fit the side wall 14.

[0063] In some embodiments, for diverting materials, the inclination angle of the side wall 14 of the discharge channel 13 is greater than the repose angle of the material.

[0064] It should be noted that the angle of repose of a material refers to the minimum angle between the inclined surface and the horizontal surface when the inclined surface causes the material placed thereon to be in a critical state of sliding down the inclined surface (i.e., as the inclination angle increases, the material on the inclined surface will slide more easily; when the object reaches a state where it begins to slide down, the angle of the critical state is called the angle of repose). Therefore, in the embodiment of the present application, the inclination angle of the side wall 14 of the discharge channel 13 is set to be greater than the angle of repose of the material, so as to further avoid the occurrence of material accumulation.

[0065] In some embodiments, the inclination angle of the flap 2 at the stop position matches the physical properties of the material.

[0066] It is understandable that the physical properties of the material include but are not limited to the type of material, material transport volume, water content, viscosity, etc. Setting the inclination angle of the flap 2 in the stop position according to the physical properties of the material can avoid the occurrence of situations such as the material sticking to the flap 2.

[0067] It is to be understood that the features, structures or characteristics described in the embodiments of the present application may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application.
