Abstract
Description
Technical Field
[0001] This utility model relates to the field of material conveying system technology, specifically to a three-way valve. Background Technology
[0002] Materials between upper and lower belt conveyors are transferred via chutes. Some materials on the belts need to be diverted, which is done by using a type-1 electric tee.
[0003] The 1 / 2-type electric tee is widely used, mainly in projects where the lower opening of the head funnel does not coincide with the center of the two downstream conveyor belts. Because the baffle needs to rotate to switch positions, a gap needs to be reserved between the baffle wing and the tee housing. However, the 1 / 2-type electric tee currently suffers from material jamming between the baffle wing and the tee housing, resulting in a high equipment failure rate and difficulty in maintenance. Furthermore, due to the gap between the baffle wing and the housing, dust from the material can drift into the bypass chute and scatter into the air, increasing the dust concentration in the transfer station and seriously impacting the health of workers. Utility Model Content
[0004] Based on the above description, this utility model provides a three-way valve to solve the problems of material jamming and dust leakage from the bypass during material distribution in existing 1-type electric three-way valves.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0006] A tee includes: a housing, a baffle, and a flexible seal;
[0007] The housing has an inner cavity with an inlet and two outlets, both of which are located below the inlet;
[0008] The lower end of the baffle is rotatably mounted inside the inner cavity and is located between the two outlets, so that the inlet is connected to one of the outlets or the other outlet;
[0009] The flexible seal is used to seal the gap between the two sides of the baffle and the housing;
[0010] The housing has two protrusions, which are located on both sides of the inlet and are respectively provided on both sides of the baffle. The two sides of the baffle protrude from the inlet and are located on the lower side of the two protrusions.
[0011] Based on the above technical solution, the present invention can be further improved as follows:
[0012] Furthermore, the baffle includes a plate body and two wing plates. The two wing plates are respectively connected to both sides of the plate body and form two chutes distributed along the thickness direction of the plate body with the baffle. Each chute is arranged to run vertically.
[0013] Furthermore, the periphery of each of the wing plates near the inlet is configured to connect to the periphery;
[0014] The flexible seal includes at least two rubber strips, each of which is connected to a connection periphery, and the opposite sides of the two rubber strips abut against the cavity wall of the inner cavity.
[0015] Furthermore, the baffle also includes at least two connecting plates, each connecting plate being adapted to and connected to a connecting periphery, and each connecting plate having a plurality of threaded holes spaced apart along the extending direction of the connecting plate;
[0016] The rubber strip is provided with multiple through holes, and each of the multiple through holes corresponds to a multiple of the threaded holes;
[0017] The tee also includes multiple bolts that correspond one-to-one with the multiple threaded holes.
[0018] Furthermore, the tee also includes at least two pivots, which are respectively connected to opposite sides of the two wing plates and are coaxially arranged.
[0019] The housing is provided with two through-holes for the two rotating shafts to pass through.
[0020] The tee also includes at least two bearing seats, with each bearing seat corresponding to one of the two rotating holes.
[0021] Furthermore, the tee also includes a crank arm and an electric push rod, with one end of the crank arm connected to the pivot shaft and the drive end of the electric push rod connected to the other end of the crank arm.
[0022] Furthermore, each of the aforementioned protrusions is arc-shaped and adapted to the movement trajectory of the upper end of the baffle.
[0023] Furthermore, the housing is provided with an observation port;
[0024] The tee also includes an observation door, which is detachably installed in the observation port.
[0025] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0026] In this embodiment, the housing has two protrusions, each corresponding to one side of the baffle. The two sides of the baffle protrude from the inlet and are located below the two protrusions, thus concealing the two sides of the baffle within the lower sides of the protrusions. This prevents material from falling from the top of the baffle into the gap between the two sides of the baffle and the housing when entering the inner cavity from the inlet, avoiding material jamming. The flexible seal seals the gap between the two sides of the baffle and the housing, preventing dust from leaking out of the other outlet when one outlet is used for material transport; thus preventing dust leakage without affecting the normal rotation and switching of the baffle between work positions.

[0041] Please refer to Figure 1 , Figure 2 and Figure 7This utility model provides a tee, comprising: a housing 1, a baffle 2, and a flexible sealing element 3; the housing 1 has an inner cavity 11, the inner cavity 11 has an inlet 12 and two outlets 13, both of the outlets 13 being located below the inlet 12; the lower end of the baffle 2 is rotatably mounted in the inner cavity 11 and located between the two outlets 13, so that the inlet 12 is connected to one of the outlets 13 or the other outlet 13; the flexible sealing element 3 is used to seal the gap between the two sides of the baffle 2 and the housing 1; wherein, the housing 1 forms two protrusions 14, the two protrusions 14 being located on both sides of the inlet 12 and respectively corresponding to the two sides of the baffle 2, the two sides of the baffle 2 protruding away from the inlet 12 and respectively located below the two protrusions 14.
[0042] In this embodiment, the housing 1 has two protrusions 14, which correspond to the two sides of the baffle 2. The two sides of the baffle 2 protrude from the inlet 12 and are located below the two protrusions 14, thus concealing the two sides of the baffle 2 within the two protrusions 14. This prevents material from falling from the top of the baffle 2 into the gap between the two sides of the baffle 2 and the housing 1 when entering the inner cavity 11 from the inlet 12, thus avoiding material jamming. The flexible seal 3 seals the gap between the two sides of the baffle 2 and the housing 1, preventing dust from leaking out of the other outlet 13 through the gap when one outlet 13 is used to transport material; thus preventing dust leakage without affecting the normal rotation and switching of the baffle 2.
[0043] In this embodiment, refer to Figure 1 , Figure 2 and Figure 7 The baffle 2 includes a main body 21 and two wing plates 22. The two wing plates 22 are respectively connected to both sides of the main body 21 in the width direction, and together with the baffle 2, they form two chutes 23 distributed along the thickness direction of the main body 21. Each chute 23 is arranged vertically. The baffle 2 rotates to switch different chutes 23 to connect with the inlet 12, thereby connecting the inlet 12 with different outlets 13. Furthermore, the wing plates 22 serve to guide the transport of materials, prevent materials from directly impacting the housing 1, and strengthen the structure of the three-way valve.
[0044] Reference Figure 7 The two sides of the plate body 21 in the width direction are respectively connected to the middle of the two wing plates 22; the two chutes 23 are the same.
[0045] It should be noted that, in this embodiment, with the plate body 21 as the reference, the vertical direction corresponds to the length direction of the plate body 21; the two outlets 13 are distributed at intervals along the thickness direction of the plate body 21.
[0046] Specifically, in this embodiment, referring to Figures 2 to 4 ,as well as Figure 7 Since the material is transported from top to bottom, the periphery of each wing plate 22 near the inlet 12 is configured as a connecting periphery 221; the flexible seal 3 includes at least two rubber strips 31, each rubber strip 31 is connected to one of the connecting peripheries 221, and the opposite sides of the two rubber strips 31 abut against the cavity wall of the inner cavity 11. When the baffle 2 switches positions, each rubber strip 31 rotates with the baffle 2, which can snag and clean the cavity wall of the inner cavity 11; when the baffle 2 returns to a stationary position, it seals the gap between each wing plate 22 and the cavity wall of the inner cavity 11, preventing dust from leaking into the bypass and reducing dust in the transfer station.
[0047] In another embodiment, each of the sealing strips is disposed on the cavity wall of the inner cavity 11 to seal the gap between the connecting periphery 221 and the cavity wall of the inner cavity 11 when the baffle 2 switches positions. Furthermore, when the baffle 2 switches positions, each wing plate 22 slides relative to a corresponding rubber strip 31, thereby allowing each rubber strip to clean the wing plate 22, further resolving the material jamming problem between the housing 1 and the wing plate 22, and reducing the maintenance burden on workers.
[0048] It should be noted that the flexible sealing element 3 can also be set as a sponge strip.
[0049] In order to install each of the rubber strips 31 onto the corresponding connecting periphery 221, in this embodiment, referring to... Figures 3 to 5 ,as well as Figure 7 The baffle 2 further includes at least two connecting plates 24, each connecting plate 24 being adapted to and connected to a connecting periphery 221. Each connecting plate 24 has multiple threaded holes, which are spaced apart along the extending direction of the connecting plate 24. The rubber strip 31 has multiple through holes, each corresponding to one of the threaded holes. The flexible seal 3 also includes multiple bolts 4, each corresponding to one of the threaded holes. The rubber strip 31 covers the corresponding connecting periphery 221, and the multiple bolts 4 pass through the multiple through holes and are screwed into the multiple threaded holes, thereby connecting the rubber strip 31 to the connecting periphery 221. This design is simple and easy to manufacture.
[0050] More specifically, refer to Figure 7In this embodiment, each connecting periphery 221 includes an upper side and two first side edges respectively connected to both ends of the upper side. The two first side edges are spaced apart along the width direction of the plate body 21, and are inclined away from each other from top to bottom, so that when the baffle 2 connects the inlet 12 with one of the outlets 13, the wing plate 22 adapts to the cavity wall of the inner cavity 11. In this embodiment, the baffle 2 also includes at least two reinforcing plates 25, which are respectively disposed corresponding to the two chutes 23, and both ends of each reinforcing plate 25 are respectively connected to the lower ends of the two first side edges. This further strengthens the structure of the baffle 2 and avoids the distance between the two wing plates 22 from increasing due to the impact of materials, which would cause the distance between the wing plates 22 and the housing 1 to be too small, resulting in interference between the baffle 2 and the housing 1 when the baffle 2 rotates. Thus, stability is improved and service life is extended.
[0051] In this embodiment, refer to Figure 1 and Figure 7 The tee also includes at least two rotating shafts 5, which are respectively connected to opposite sides of the two wing plates 22 and are coaxially arranged. The housing 1 has two through-holes for the two rotating shafts 5 to pass through. The tee also includes at least two bearing seats 6, which are respectively arranged corresponding to the two rotating holes. The two rotating shafts pass through the two rotating holes and are rotatably connected to the two bearing seats 6, thereby rotatably connecting the baffle 2 to the housing 1.
[0052] In another embodiment, the rotating shaft 5 may be located on the housing 1, and the rotating hole may be located on the wing plate 22.
[0053] In order to drive the baffle 2 to rotate, in this embodiment, refer to Figure 1 and Figure 2 The tee also includes a crank arm 71 and an electric push rod 72. One end of the crank arm 71 is connected to the rotating shaft 5, and the drive end of the electric push rod 72 is connected to the other end of the crank arm 71. The push rod of the electric push rod 72 extends along the thickness direction of the plate body 21. The electric push rod 72 pushes the crank arm 71 to move, and the crank arm 71 drives the rotating shaft 5 to rotate, thereby driving the baffle 2 to rotate. Thus, the structure is simple and the driving force is strong.
[0054] In addition, the tee also includes a mounting base 73, which is mounted on the outside of the housing 1, and the electric push rod is mounted on the mounting base 73.
[0055] In this embodiment, refer to Figure 2 , Figure 3 , Figure 5and Figure 6 Each of the aforementioned protrusions 14 is arc-shaped and adapted to the movement trajectory of the upper end of the baffle 2. This reduces the gap between the upper end of the baffle 2 and the protrusion 14 without affecting the movement of the baffle 2, further preventing material from entering between the housing 1 and the wing plate 22.
[0056] In this embodiment, refer to Figure 2 The housing 1 is provided with an observation port 15; the tee also includes an observation door 8, which is detachably installed in the observation port 15. This allows the observation door 8 to be removed from the observation port 15, through which the condition of the inner cavity 11 can be observed.
[0057] In this embodiment, the observation port 15 is detachably installed to the observation port 15 by bolts 4. In another embodiment, the observation port 15 is provided with a locking block on its periphery, and the observation door 8 is provided with a locking groove adapted to the locking block, so that the observation door 8 can be detachably installed to the observation port 15 through the cooperation of the locking block and the locking groove.
[0058] It should be noted that the observation port 15 is detachably installed by bolt 4, which is a common technical means in the art and will not be described in detail here.
[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
