Description

Technical Field

[0001] The utility model relates to a rotary cone valve device with a heating function. Background Art

[0002] At present, some automated production lines are usually equipped with a quantitative loading host, which is equipped with a mobile insulated silo. The material in the mobile insulated silo needs to be kept warm at all times. Once the temperature of the material drops, it will cause the material to cool and solidify. The bottom of the mobile insulated silo is provided with a discharge port and a discharge valve for controlling the on / off of the discharge port. Among them, the setting of the discharge valve is particularly critical. The discharge valve must have an insulation and heating function to prevent the temperature of the material from dropping when flowing through the discharge valve and then cooling and solidifying, thereby clogging the discharge port. At present, some companies choose to use a hose valve with an insulation jacket as a discharge valve to control the on / off of the discharge port and thus control the discharge. For example, a Chinese patent with announcement number CN202481598U discloses a powder feeding device, in which a pneumatic hose valve is used to control the discharge of the material in the insulated barrel.

[0003] However, when opening and closing a hose valve with an insulation jacket, the internal hose needs to move, so the hose cannot completely adhere to the insulation jacket, resulting in poor insulation and heating effects. As a result, after prolonged use, the material gradually cools and solidifies, clogging the discharge port. In addition, hose valves with insulation jackets are prone to hose damage after prolonged use, posing a risk of material leakage. Utility Model Content

[0082] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0083] Example 1

[0084] like Figures 1 to 7 , 11 to 13, a rotary cone valve device with heating function, including a valve body 1, a valve core 2 and a pressing mechanism;

[0085] The valve body 1 is provided with a feed hole 3, a discharge hole 4 and a mounting tapered hole 5, and the feed hole 3 and the discharge hole 4 are respectively connected to the mounting tapered hole 5;

[0086] The valve core 2 is rotatably arranged in the mounting tapered hole 5, and the valve core 2 is provided with a tapered portion 6 that contacts and fits with the inner wall of the mounting tapered hole 5;

[0087] The pressing mechanism is used to apply force to the valve core 2 to press the valve core 2 into the mounting tapered hole 5 so that the tapered surface portion 6 is in close contact with the inner wall of the mounting tapered hole 5, thereby achieving sealing;

[0088] A material guide hole 7 is provided in the valve core 2, and the valve core 2 is used to drive the material guide hole 7 to rotate during the rotation process. When the material guide hole 7 rotates to be at least partially aligned with the feed hole 3 and the discharge hole 4, the feed hole 3 is connected with the discharge hole 4 through the material guide hole 7. When the material guide hole 7 rotates to be offset from at least one of the feed hole 3 and the discharge hole 4, the feed hole 3 is disconnected from the discharge hole 4.

[0089] A heat preservation and heating flow channel is provided in the valve body 1 , and the heat preservation and heating flow channel is used for allowing a heat-conducting medium to flow through so as to heat the valve body 1 and the valve core 2 .

[0090] Specifically, under the action of the clamping mechanism, the valve core 2 is pressed against the mounting tapered hole 5, causing the conical surface portion 6 of the valve core 2 to contact the inner wall of the mounting tapered hole 5, thereby achieving a seal. Rotating the valve core 2 can drive the guide hole 7 in the valve core 2 to rotate. When the guide hole 7 is rotated to align with the feed hole 3 and the discharge hole 4, respectively, the feed hole 3 can communicate with the discharge hole 4 through the guide hole 7. At this time, material can be discharged through the feed hole 3, the guide hole 7, and the discharge hole 4 in sequence, indicating an open state. When the guide hole 7 is rotated to be offset from the feed hole 3 and the discharge hole 4, the feed hole 3 is disconnected from the discharge hole 4, and material cannot be discharged, indicating a closed state. Furthermore, the opening degree can be controlled by controlling the rotation angle of the valve core 2, and the switching process is short, enabling rapid switching.

[0091] In this embodiment, the heat-conducting medium can flow through the heat-insulating heating flow channel in the valve body 1, and the heat of the heat-conducting medium can be transferred to the valve body 1 to heat the valve body 1. Then the valve body 1 heats the valve core 2 through heat transfer, thereby realizing the heat-insulating and heating function of the valve body 1 and the valve core 2, improving the heat-insulating and heating effect, and the material will not cool and solidify due to the temperature drop when it is discharged through the feed hole 3, the guide hole 7 and the discharge hole 4, avoiding the problem of cooling and solidifying the material after long-term use and then causing blockage.

[0092] In addition, even if the conical surface portion 6 on the valve core 2 is worn to a certain extent after long-term use, the clamping mechanism can apply force to drive the valve core 2 to be pressed into the mounting tapered hole 5, thereby keeping the conical surface portion 6 on the valve core 2 close to the inner wall of the mounting tapered hole 5, thereby ensuring the sealing performance, avoiding leakage caused by wear of the valve core 2, reducing the risk of leakage, and greatly extending the service life, making it sturdy and durable.

[0093] In this embodiment, the feed hole 3 and the discharge hole 4 can be coaxially arranged, and the heat transfer medium can be heat transfer oil.

[0094] like Figures 4 to 7 As shown, the valve body 1 may include a shell 8, a mounting pipe 9, a feed pipe 10, a discharge pipe 11 and at least one partition 12;

[0095] The mounting tapered hole 5 is provided in the mounting tube 9, the feed hole 3 is provided in the feed tube 10, and the discharge hole 4 is provided in the discharge tube 11;

[0096] The mounting pipe 9 , the feed pipe 10 , and the discharge pipe 11 are at least partially located inside the housing 8 ;

[0097] The upper end of the feed pipe 10 is connected to the top of the housing 8, and the lower end of the feed pipe 10 is connected to the mounting pipe 9;

[0098] The lower end of the discharge pipe 11 is connected to the bottom of the housing 8, and the upper end of the discharge pipe 11 is connected to the mounting pipe 9;

[0099] The two ends of the mounting tube 9 are respectively connected to the housing 8;

[0100] The outer wall of the mounting tube 9, the outer wall of the feed tube 10, the outer wall of the discharge tube 11 and the inner wall of the outer shell 8 surround and form an inner cavity;

[0101] The partition 12 is connected to the inner cavity and divides the inner cavity into at least two cavities, and the cavities are sequentially connected to form the heat preservation and heating flow channel;

[0102] The housing 8 is further provided with a medium inlet 13 and a medium outlet 14 , and the medium inlet 13 and the medium outlet 14 are respectively communicated with the corresponding cavity.

[0103] like Figures 4 to 7 As shown, the partition 12 is provided in multiple pieces, and the partition 12 divides the inner cavity into four cavities, namely a first cavity 15, a second cavity 16, a third cavity 17 and a fourth cavity 18 which are sequentially arranged along the circumferential direction;

[0104] The upper end of the first cavity 15 is connected to the upper end of the second cavity 16 through a first communication port 19;

[0105] The lower end of the second cavity 16 is connected to the lower end of the third cavity 17 through a second communication port 20;

[0106] The upper end of the third cavity 17 is connected to the upper end of the fourth cavity 18 through a third communication port 21;

[0107] The medium inlet 13 is connected to the lower end of the first cavity 15;

[0108] The medium outlet 14 is connected to the lower end of the fourth cavity 18;

[0109] The medium inlet 13, the first cavity 15, the second cavity 16, the third cavity 17, the fourth cavity 18, and the medium outlet 14 are sequentially connected to form the heat-insulating heating channel. Specifically, when the heat-conducting medium flows through the heat-insulating heating channel, it can heat the entire valve body 1. Then, the valve body 1 heats the valve core 2 through heat transfer, thereby achieving the heat-insulating and heating function of the valve body 1, the valve core 2, and the material flowing through. In this embodiment, the shell 8, the mounting tube 9, the feed tube 10, the discharge tube 11, and the partition 12 can all be made of 304 stainless steel, and the valve core 2 can be made of aluminum bronze, thereby preventing sparks when the valve is opened to avoid safety issues.

[0110] like Figure 1 、 12 As shown in FIG. 13 , the pressing mechanism is connected to the valve body 1 , and the pressing mechanism may include a fixing component, an elastic component 40 and a pressing plate 41 ;

[0111] The fixing component is connected to the valve body 1;

[0112] The pressure plate 41 is slidably connected to the fixed component and is used to abut against the valve core 2;

[0113] The elastic component 40 is arranged between the fixing component and the pressure plate 41 and is used to drive the pressure plate 41 to press against the valve core 2 through elastic force, thereby pressing the valve core 2 into the mounting tapered hole 5, and then making the conical surface part 6 close to the inner wall of the mounting tapered hole 5 to achieve sealing.

[0114] like Figure 1 、 12 As shown in FIG. 13 , the fixing member includes at least two threaded rods 42 and abutment nuts 43 connected to the threaded rods 42 , and the elastic member 40 includes a spring corresponding to the threaded rods 42 ;

[0115] The threaded rod 42 is connected to the valve body 1;

[0116] The pressure plate 41 is slidably connected to the threaded rod 42 and abuts against the valve core 2;

[0117] The spring is sleeved on the corresponding threaded rod 42, one end of the spring abuts against the abutment nut 43, and the other end of the spring abuts against the pressure plate 41. The spring is used to drive the pressure plate 41 to press against the valve core 2, thereby pressing the valve core 2 into the mounting tapered hole 5. In this embodiment, a plurality of threaded rods 42 are evenly distributed along the circumferential direction, each of which is connected to the abutment nut 43. The pressure plate 41 is provided with a rod hole corresponding to each threaded rod 42. The pressure plate 41 is slidably connected to the threaded rod 42 through the rod hole. The spring corresponds to the threaded rod 42 and is sleeved on the corresponding threaded rod 42. Specifically, by screwing the abutment nut 43, the compression amount of the spring can be adjusted, and thus the pressure pressing the pressure plate 41 and the valve core 2 can be adjusted, so that the conical surface portion 6 on the valve core 2 can be in close contact with the inner wall of the mounting tapered hole 5, thereby achieving a reliable seal.

[0118] like Figures 11-13 As shown, the rotary cone valve device with heating function may further include a docking assembly 100 and a valve opening drive mechanism 200;

[0119] The docking assembly 100 is connected to the valve core 2;

[0120] The valve opening drive mechanism 200 is used to connect to the docking assembly 100 and drive the docking assembly 100 to rotate, thereby driving the valve core 2 to rotate. During the rotation process, the valve core 2 can drive the guide hole 7 to rotate. When the guide hole 7 rotates to align with the feed hole 3 and the discharge hole 4, the feed hole 3 can be connected to the discharge hole 4 through the guide hole 7. At this time, the material can be discharged through the feed hole 3, the guide hole 7 and the discharge hole 4 in sequence, indicating an open state. When the guide hole 7 rotates to offset the feed hole 3 and the discharge hole 4, the feed hole 3 is disconnected from the discharge hole 4. At this time, the material cannot be discharged, indicating a closed state.

[0121] like Figures 11-13 As shown, the valve opening drive mechanism 200 may include a fixed seat 44, a sliding seat 45, a linear drive component 46, a rotation drive component 47 and a drive rod 48;

[0122] The sliding seat 45 is slidably connected to the fixed seat 44;

[0123] The rotation driving component 47 is connected to the sliding seat 45;

[0124] The driving rod 48 is connected to the rotation driving component 47. The driving rod 48 is provided with a first docking portion 49. The docking assembly 100 is provided with a second docking portion 50 for cooperating with the first docking portion 49 to transmit torque.

[0125] The linear drive component 46 is connected to the fixed seat 44 and is connected to the sliding seat 45. The linear drive component 46 is used to drive the sliding seat 45 to move forward, thereby driving the rotation drive component 47 and the drive rod 48 to move forward so that the first docking portion 49 on the drive rod 48 moves forward to cooperate with the second docking portion 50. The linear drive component 46 is also used to drive the sliding seat 45 to move backward, thereby driving the rotation drive component 47 and the drive rod 48 to move backward so that the first docking portion 49 is disconnected from the second docking portion 50.

[0126] The rotation driving component 47 is used to drive the driving rod 48 to rotate when the first docking portion 49 is connected to the second docking portion 50 , thereby driving the docking assembly 100 to rotate and further driving the valve core 2 to rotate.

[0127] Specifically, the valve assembly is composed of at least the valve body 1, the valve core 2 and the clamping mechanism. The valve assembly can be connected to the bottom of the mobile insulation silo and is used to control the discharge of materials in the mobile insulation silo. First, the mobile insulation silo is transported to the target position with the valve assembly, and then the linear drive component 46 drives the sliding seat 45 to move forward and then drives the rotary drive component 47 and the drive rod 48 to move forward, so that the first docking portion 49 on the drive rod 48 moves forward to cooperate with the second docking portion 50, and then the rotary drive component 47 drives the drive rod 48 to rotate and then drives the docking assembly 100 to rotate, and then drives the valve core 2 to rotate a certain angle, so as to rotate the guide hole 7 on the valve core 2 to align with the feed hole 3 and the discharge hole 4 respectively. At this time, the valve assembly is opened and the material in the mobile insulation silo can be discharged. After the discharge is completed, the rotary drive component 47 drives the drive rod 48 to rotate, and the drive rod 48 then drives the docking assembly 100 to rotate and then drives the valve core 2 to rotate back to the closed position, so as to rotate the guide hole 7 on the valve core 2 to be staggered with the feed hole 3 and the discharge hole 4 respectively. At this time, the valve assembly is closed and the material in the mobile insulation silo cannot be discharged. When all the materials in the mobile insulation silo are discharged, the linear drive component 46 drives the sliding seat 45 to move backward and then drives the rotary drive component 47 and the drive rod 48 to move backward, so that the first docking part 49 is disconnected from the second docking part 50, and then the mobile insulation silo can be transported away, thus completing a cycle.

[0128] Specifically, the valve opening drive mechanism 200 further includes a sensing element 51, a sensor 52 and a controller;

[0129] The controller is connected to the rotation drive component 47 and is used to control the movement of the rotation drive component 47;

[0130] The induction member 51 is connected to the output shaft of the rotation drive component 47 or to the drive rod 48 so that the induction member 51 rotates synchronously with the drive rod 48;

[0131] The sensor 52 is connected to the sliding seat 45 and is configured to send a signal to the controller when the sensing element 51 rotates to align with the sensor 52. In this embodiment, before the first docking portion 49 and the second docking portion 50 separate, the controller first controls the rotation drive component 47 to rotate the sensing element 51 to align with the sensor 52, and then separates the first docking portion 49 and the second docking portion 50. Similarly, before the first docking portion 49 and the second docking portion 50 are docked and connected, the controller first controls the rotation drive component 47 to rotate the sensing element 51 to align with the sensor 52, and then docks and connects the first docking portion 49 and the second docking portion 50. This ensures that the first docking portion 49 accurately aligns with the second docking portion 50 every time. The sensor 52 may be a proximity switch, the first docking portion 49 may be a straight-edge screw, and the second docking portion 50 may be a straight-edge slot, wherein the straight-edge slot has a chamfered corner for guiding the straight-edge screw into the straight-edge slot.

[0132] In this embodiment, the linear drive component 46 may be a cylinder, and the rotary drive component 47 may be a servo reduction motor. The servo reduction motor can precisely control the rotation angle of the valve core 2, thereby precisely controlling the opening of the valve assembly. This embodiment also includes a protective cover for covering the sliding seat 45, the linear drive component 46, and the rotary drive component 47.

[0133] like Figure 12 、 13 As shown, the docking assembly 100 may include a docking shaft 53, a connecting rod 54 and a sleeve 55;

[0134] The shaft sleeve 55 is fixedly arranged;

[0135] The docking shaft 53 is connected to the sleeve 55 so as to be rotatable relative to the sleeve 55 in the circumferential direction but immovable relative to the sleeve 55 in the axial direction. The second docking portion 50 is provided on the docking shaft 53.

[0136] One end of the connecting rod 54 is connected to the docking shaft 53, and the other end of the connecting rod 54 is connected to the valve core 2. Specifically, when the linear drive component 46 drives the drive rod 48 forward, the first docking portion 49 on the drive rod 48 moves forward until it mates with the second docking portion 50 on the docking shaft 53. Then, the rotary drive component 47 drives the drive rod 48 to rotate, thereby driving the docking shaft 53 to rotate, and further driving the valve core 2 to rotate via the connecting rod 54. When the linear drive component 46 drives the drive rod 48 backward, the first docking portion 49 on the drive rod 48 moves backward until it is disconnected from the second docking portion 50 on the docking shaft 53.

[0137] In this embodiment, the docking shaft 53 is rotatably connected to the sleeve 55 via a bearing. The bearing can be secured by a spring retaining ring, thereby preventing the docking shaft 53 from axially moving relative to the sleeve 55. The purpose of this design is that when the first docking portion 49 on the driving rod 48 moves forward to engage with the second docking portion 50 on the docking shaft 53, the driving rod 48 applies an axial force to the docking shaft 53. The sleeve 55 receives the axial force applied by the driving rod 48 to the docking shaft 53, thereby preventing the axial force from being transmitted to the valve core 2 via the connecting rod 54. This, in turn, prevents the valve core 2 from being crushed and unable to rotate in the mounting tapered hole 5 by the axial force.

[0138] like Figure 1 、 12 As shown in FIG. 13 , the valve core 2 is provided with a first transmission hole 56 , and the docking shaft 53 is provided with a second transmission hole 57 ;

[0139] One end of the connecting rod 54 is provided with a first transmission head 58 which is fitted in the first transmission hole 56 and is used to transmit torque;

[0140] The other end of the connecting rod 54 is provided with a second transmission head 59 which is fitted in the second transmission hole 57 and is used to transmit torque;

[0141] A spacing space is provided between the end surface of the first transmission head 58 and the bottom surface of the first transmission hole 56, and / or between the end surface of the second transmission head 59 and the bottom surface of the second transmission hole 57. Specifically, the spacing space is provided to prevent axial force from being transmitted to the valve core 2 via the connecting rod 54, thereby preventing the valve core 2 from being subjected to the axial force and being crushed and unable to rotate in the mounting tapered hole 5. In this embodiment, the first transmission hole 56 and the second transmission hole 57 are both hexagonal holes, and the first transmission head 58 and the second transmission head 59 are both hexagonal heads. Therefore, the docking shaft 53 can transmit torque to the valve core 2 via the connecting rod 54, thereby driving the valve core 2 to rotate.

[0142] Specifically, the shaft sleeve 55 can be fixedly mounted on the mobile heat-insulating silo. During disassembly, the shaft sleeve 55 can be first removed from the mobile heat-insulating silo, and then the connecting rod 54 can be removed. Finally, the abutment nut 43 can be unscrewed, and the spring and pressure plate 41 can be removed. After that, the valve core 2 can be removed for cleaning. After cleaning, the installation sequence is the opposite of the disassembly sequence. It can be seen that the disassembly and installation of the valve core 2 in this embodiment is very convenient, and thus easy to clean and replace.

[0143] Example 2

[0144] like Figures 1 to 3 8 to 13, another rotary cone valve device with heating function includes a valve body 1, a valve core 2 and a pressing mechanism;

[0145] The valve body 1 is provided with a feed hole 3, a discharge hole 4 and a mounting tapered hole 5, and the feed hole 3 and the discharge hole 4 are respectively connected to the mounting tapered hole 5;

[0146] The valve core 2 is rotatably arranged in the mounting tapered hole 5, and the valve core 2 is provided with a tapered portion 6 that contacts and fits with the inner wall of the mounting tapered hole 5;

[0147] The pressing mechanism is used to apply force to the valve core 2 to press the valve core 2 into the mounting tapered hole 5 so that the tapered surface portion 6 is in close contact with the inner wall of the mounting tapered hole 5, thereby achieving sealing;

[0148] A material guide hole 7 is provided in the valve core 2, and the valve core 2 is used to drive the material guide hole 7 to rotate during the rotation process. When the material guide hole 7 rotates to be at least partially aligned with the feed hole 3 and the discharge hole 4, the feed hole 3 is connected with the discharge hole 4 through the material guide hole 7. When the material guide hole 7 rotates to be offset from at least one of the feed hole 3 and the discharge hole 4, the feed hole 3 is disconnected from the discharge hole 4.

[0149] The valve body 1 is provided with a heat preservation and heating flow channel, and the heat preservation and heating flow channel is used for allowing a heat-conducting medium to flow through so as to heat the valve body 1 and the valve core 2 in a heat preservation manner.

[0150] Specifically, under the action of the clamping mechanism, the valve core 2 is pressed against the mounting tapered hole 5, causing the conical surface portion 6 of the valve core 2 to contact the inner wall of the mounting tapered hole 5, thereby achieving a seal. Rotating the valve core 2 can drive the guide hole 7 in the valve core 2 to rotate. When the guide hole 7 is rotated to align with the feed hole 3 and the discharge hole 4, respectively, the feed hole 3 can communicate with the discharge hole 4 through the guide hole 7. At this time, material can be discharged through the feed hole 3, the guide hole 7, and the discharge hole 4 in sequence, indicating an open state. When the guide hole 7 is rotated to be offset from the feed hole 3 and the discharge hole 4, the feed hole 3 is disconnected from the discharge hole 4, and material cannot be discharged, indicating a closed state. Furthermore, the opening degree can be controlled by controlling the rotation angle of the valve core 2, and the switching process is short, enabling rapid switching.

[0151] In this embodiment, the heat-conducting medium can flow through the heat-insulating heating flow channel in the valve body 1, and the heat of the heat-conducting medium can be transferred to the valve body 1 to heat the valve body 1. Then the valve body 1 heats the valve core 2 through heat transfer, thereby realizing the heat-insulating and heating function of the valve body 1 and the valve core 2, improving the heat-insulating and heating effect, and the material will not cool and solidify due to the temperature drop when it is discharged through the feed hole 3, the guide hole 7 and the discharge hole 4, avoiding the problem of cooling and solidifying the material after long-term use and then causing blockage.

[0152] In addition, even if the conical surface portion 6 on the valve core 2 is worn to a certain extent after long-term use, the clamping mechanism can apply force to drive the valve core 2 to be pressed into the mounting tapered hole 5, thereby keeping the conical surface portion 6 on the valve core 2 close to the inner wall of the mounting tapered hole 5, thereby ensuring the sealing performance, avoiding leakage caused by wear of the valve core 2, reducing the risk of leakage, and greatly extending the service life, making it sturdy and durable.

[0153] In this embodiment, the feed hole 3 and the discharge hole 4 can be coaxially arranged, and the heat transfer medium can be heat transfer oil.

[0154] like Figures 8-10 As shown, the valve body 1 may include a main body block, and the mounting cone hole 5, the feed hole 3 and the discharge hole 4 are all provided in the main body block;

[0155] The main body block may also be provided with an inlet channel 22, an outlet channel 23 and at least one flow channel assembly, and the flow channel assembly is respectively connected to the inlet channel 22 and the outlet channel 23 so that the heat-conducting medium flowing into the inlet channel 22 flows through the flow channel assembly and is discharged from the outlet channel 23; in this embodiment, the flow channel assemblies are arranged in parallel.

[0156] The flow channel assembly may include a first channel 24, a second channel 25, a third channel 26, a fourth channel 27, a fifth channel 28, a sixth channel 29, a first flow channel hole 30 and a second flow channel hole 31;

[0157] A first plate 32 is provided in the first flow channel 30. The first plate 32 divides the first flow channel 30 into a first upper cavity 33 located above the first plate 32 and a first lower cavity 34 located below the first plate 32. The first plate 32 is provided with a first guide hole 35 for connecting the first upper cavity 33 with the first lower cavity 34.

[0158] A second plate 36 is provided in the second flow channel 31. The second plate 36 divides the second flow channel 31 into a second upper channel 37 located above the second plate 36 and a second lower channel 38 located below the second plate 36. The second plate 36 is provided with a second guide hole 39 for connecting the second upper channel 37 with the second lower channel 38.

[0159] The inlet channel 22 is connected to one end of the first channel 24;

[0160] The other end of the first channel 24 is connected to one end of the second channel 25;

[0161] The other end of the second channel 25 is connected to one end of the first lower cavity 34;

[0162] The other end of the first lower cavity 34 is connected to one end of the first upper cavity 33 through the first guide hole 35;

[0163] The other end of the first upper cavity 33 is connected to one end of the third channel 26;

[0164] The other end of the third channel 26 is connected to one end of the second lower cavity 38;

[0165] The other end of the second lower cavity 38 is connected to one end of the second upper cavity 37 through the second guide hole 39;

[0166] The other end of the second upper cavity 37 is connected to one end of the fourth channel 27;

[0167] The other end of the fourth channel 27 is connected to one end of the fifth channel 28;

[0168] The other end of the fifth channel 28 is connected to one end of the sixth channel 29;

[0169] The other end of the sixth channel 29 is connected to the outlet channel 23; in this embodiment, the first flow channel hole 30 is arranged in the horizontal direction and is located below the mounting cone hole 5, the first channel 24 is arranged in the horizontal direction and is located below the first flow channel hole 30, the second flow channel hole 31 is arranged in the horizontal direction and is located above the mounting cone hole 5, and the fifth channel 28 is arranged in the horizontal direction and is located above the second flow channel hole 31. The second, third, and fourth channels 25, 26, and 27 are coaxially arranged and vertically disposed. The sixth channel 29 is also vertically disposed. The heat transfer medium sequentially flows through the inlet channel 22, the first channel 24, the second channel 25, the first lower cavity 34, the first upper cavity 33, the third channel 26, the second lower cavity 38, the second upper cavity 37, the fourth channel 27, the fifth channel 28, and the sixth channel 29 before exiting the outlet channel 23. The heat transfer medium heats the entire valve body 1 as it flows. The valve body 1 then heats the valve core 2 through heat transfer, thereby achieving a heat preservation and heating function for the valve body 1, valve core 2, and the material flowing through it. In this embodiment, the main body block may be made of aluminum alloy, and the valve core 2 may be made of aluminum bronze, thereby preventing sparks when the valve is opened to avoid safety issues.

[0170] like Figure 1 、 12 As shown in FIG. 13 , the pressing mechanism is connected to the valve body 1 , and the pressing mechanism may include a fixing component, an elastic component 40 and a pressing plate 41 ;

[0171] The fixing component is connected to the valve body 1;

[0172] The pressure plate 41 is slidably connected to the fixed component and is used to abut against the valve core 2;

[0173] The elastic component 40 is arranged between the fixing component and the pressure plate 41 and is used to drive the pressure plate 41 to press against the valve core 2 through elastic force, thereby pressing the valve core 2 into the mounting tapered hole 5, and then making the conical surface part 6 close to the inner wall of the mounting tapered hole 5 to achieve sealing.

[0174] like Figure 1 、 12 As shown in FIG. 13 , the fixing member includes at least two threaded rods 42 and abutment nuts 43 connected to the threaded rods 42 , and the elastic member 40 includes a spring corresponding to the threaded rods 42 ;

[0175] The threaded rod 42 is connected to the valve body 1;

[0176] The pressure plate 41 is slidably connected to the threaded rod 42 and abuts against the valve core 2;

[0177] The spring is sleeved on the corresponding threaded rod 42, one end of the spring abuts against the abutment nut 43, and the other end of the spring abuts against the pressure plate 41. The spring is used to drive the pressure plate 41 to press against the valve core 2, thereby pressing the valve core 2 into the mounting tapered hole 5. In this embodiment, a plurality of threaded rods 42 are evenly distributed along the circumferential direction, each of which is connected to the abutment nut 43. The pressure plate 41 is provided with a rod hole corresponding to each threaded rod 42. The pressure plate 41 is slidably connected to the threaded rod 42 through the rod hole. The spring corresponds to the threaded rod 42 and is sleeved on the corresponding threaded rod 42. Specifically, by screwing the abutment nut 43, the compression amount of the spring can be adjusted, and thus the pressure pressing the pressure plate 41 and the valve core 2 can be adjusted, so that the conical surface portion 6 on the valve core 2 can be in close contact with the inner wall of the mounting tapered hole 5, thereby achieving a reliable seal.

[0178] like Figures 11-13 As shown, the rotary cone valve device with heating function may further include a docking assembly 100 and a valve opening drive mechanism 200;

[0179] The docking assembly 100 is connected to the valve core 2;

[0180] The valve opening drive mechanism 200 is used to connect to the docking assembly 100 and drive the docking assembly 100 to rotate, thereby driving the valve core 2 to rotate. During the rotation process, the valve core 2 can drive the guide hole 7 to rotate. When the guide hole 7 rotates to align with the feed hole 3 and the discharge hole 4, the feed hole 3 can be connected to the discharge hole 4 through the guide hole 7. At this time, the material can be discharged through the feed hole 3, the guide hole 7 and the discharge hole 4 in sequence, indicating an open state. When the guide hole 7 rotates to offset the feed hole 3 and the discharge hole 4, the feed hole 3 is disconnected from the discharge hole 4. At this time, the material cannot be discharged, indicating a closed state.

[0181] like Figures 11-13 As shown, the valve opening drive mechanism 200 may include a fixed seat 44, a sliding seat 45, a linear drive component 46, a rotation drive component 47 and a drive rod 48;

[0182] The sliding seat 45 is slidably connected to the fixed seat 44;

[0183] The rotation driving component 47 is connected to the sliding seat 45;

[0184] The driving rod 48 is connected to the rotation driving component 47. The driving rod 48 is provided with a first docking portion 49. The docking assembly 100 is provided with a second docking portion 50 for cooperating with the first docking portion 49 to transmit torque.

[0185] The linear drive component 46 is connected to the fixed seat 44 and is connected to the sliding seat 45. The linear drive component 46 is used to drive the sliding seat 45 to move forward, thereby driving the rotation drive component 47 and the drive rod 48 to move forward so that the first docking portion 49 on the drive rod 48 moves forward to cooperate with the second docking portion 50. The linear drive component 46 is also used to drive the sliding seat 45 to move backward, thereby driving the rotation drive component 47 and the drive rod 48 to move backward so that the first docking portion 49 is disconnected from the second docking portion 50.

[0186] The rotation driving component 47 is used to drive the driving rod 48 to rotate when the first docking portion 49 is connected to the second docking portion 50 , thereby driving the docking assembly 100 to rotate and further driving the valve core 2 to rotate.

[0187] Specifically, the valve assembly is composed of at least the valve body 1, the valve core 2 and the clamping mechanism. The valve assembly can be connected to the bottom of the mobile insulation silo and is used to control the discharge of materials in the mobile insulation silo. First, the mobile insulation silo is transported to the target position with the valve assembly, and then the linear drive component 46 drives the sliding seat 45 to move forward and then drives the rotary drive component 47 and the drive rod 48 to move forward, so that the first docking portion 49 on the drive rod 48 moves forward to cooperate with the second docking portion 50, and then the rotary drive component 47 drives the drive rod 48 to rotate and then drives the docking assembly 100 to rotate, and then drives the valve core 2 to rotate a certain angle, so as to rotate the guide hole 7 on the valve core 2 to align with the feed hole 3 and the discharge hole 4 respectively. At this time, the valve assembly is opened and the material in the mobile insulation silo can be discharged. After the discharge is completed, the rotary drive component 47 drives the drive rod 48 to rotate, and the drive rod 48 then drives the docking assembly 100 to rotate and then drives the valve core 2 to rotate back to the closed position, so as to rotate the guide hole 7 on the valve core 2 to be staggered with the feed hole 3 and the discharge hole 4 respectively. At this time, the valve assembly is closed and the material in the mobile insulation silo cannot be discharged. When all the materials in the mobile insulation silo are discharged, the linear drive component 46 drives the sliding seat 45 to move backward and then drives the rotary drive component 47 and the drive rod 48 to move backward, so that the first docking part 49 is disconnected from the second docking part 50, and then the mobile insulation silo can be transported away, thus completing a cycle.

[0188] Specifically, the valve opening drive mechanism 200 further includes a sensing element 51, a sensor 52 and a controller;

[0189] The controller is connected to the rotation drive component 47 and is used to control the movement of the rotation drive component 47;

[0190] The induction member 51 is connected to the output shaft of the rotation drive component 47 or to the drive rod 48 so that the induction member 51 rotates synchronously with the drive rod 48;

[0191] The sensor 52 is connected to the sliding seat 45 and is configured to send a signal to the controller when the sensing element 51 rotates to align with the sensor 52. In this embodiment, before the first docking portion 49 and the second docking portion 50 separate, the controller first controls the rotation drive component 47 to rotate the sensing element 51 to align with the sensor 52, and then separates the first docking portion 49 and the second docking portion 50. Similarly, before the first docking portion 49 and the second docking portion 50 are docked and connected, the controller first controls the rotation drive component 47 to rotate the sensing element 51 to align with the sensor 52, and then docks and connects the first docking portion 49 and the second docking portion 50. This ensures that the first docking portion 49 accurately aligns with the second docking portion 50 every time. The sensor 52 may be a proximity switch, the first docking portion 49 may be a straight-edge screw, and the second docking portion 50 may be a straight-edge slot, wherein the straight-edge slot has a chamfered corner for guiding the straight-edge screw into the straight-edge slot.

[0192] In this embodiment, the linear drive component 46 may be a cylinder, and the rotary drive component 47 may be a servo reduction motor. The servo reduction motor can precisely control the rotation angle of the valve core 2, thereby precisely controlling the opening of the valve assembly. This embodiment also includes a protective cover for covering the sliding seat 45, the linear drive component 46, and the rotary drive component 47.

[0193] like Figure 12 、 13 As shown, the docking assembly 100 may include a docking shaft 53, a connecting rod 54 and a sleeve 55;

[0194] The shaft sleeve 55 is fixedly arranged;

[0195] The docking shaft 53 is connected to the sleeve 55 so as to be rotatable relative to the sleeve 55 in the circumferential direction but immovable relative to the sleeve 55 in the axial direction. The second docking portion 50 is provided on the docking shaft 53.

[0196] One end of the connecting rod 54 is connected to the docking shaft 53, and the other end of the connecting rod 54 is connected to the valve core 2. Specifically, when the linear drive component 46 drives the drive rod 48 forward, the first docking portion 49 on the drive rod 48 moves forward until it mates with the second docking portion 50 on the docking shaft 53. Then, the rotary drive component 47 drives the drive rod 48 to rotate, thereby driving the docking shaft 53 to rotate, and further driving the valve core 2 to rotate via the connecting rod 54. When the linear drive component 46 drives the drive rod 48 backward, the first docking portion 49 on the drive rod 48 moves backward until it is disconnected from the second docking portion 50 on the docking shaft 53.

[0197] In this embodiment, the docking shaft 53 is rotatably connected to the sleeve 55 via a bearing. The bearing can be secured by a spring retaining ring, thereby preventing the docking shaft 53 from axially moving relative to the sleeve 55. The purpose of this design is that when the first docking portion 49 on the driving rod 48 moves forward to engage with the second docking portion 50 on the docking shaft 53, the driving rod 48 applies an axial force to the docking shaft 53. The sleeve 55 receives the axial force applied by the driving rod 48 to the docking shaft 53, thereby preventing the axial force from being transmitted to the valve core 2 via the connecting rod 54. This, in turn, prevents the valve core 2 from being crushed and unable to rotate in the mounting tapered hole 5 by the axial force.

[0198] like Figure 1 、 12 As shown in FIG. 13 , the valve core 2 is provided with a first transmission hole 56 , and the docking shaft 53 is provided with a second transmission hole 57 ;

[0199] One end of the connecting rod 54 is provided with a first transmission head 58 which is fitted in the first transmission hole 56 and is used to transmit torque;

[0200] The other end of the connecting rod 54 is provided with a second transmission head 59 which is fitted in the second transmission hole 57 and is used to transmit torque;

[0201] A spacing space is provided between the end surface of the first transmission head 58 and the bottom surface of the first transmission hole 56, and / or between the end surface of the second transmission head 59 and the bottom surface of the second transmission hole 57. Specifically, the spacing space is provided to prevent axial force from being transmitted to the valve core 2 via the connecting rod 54, thereby preventing the valve core 2 from being subjected to the axial force and being crushed and unable to rotate in the mounting tapered hole 5. In this embodiment, the first transmission hole 56 and the second transmission hole 57 are both hexagonal holes, and the first transmission head 58 and the second transmission head 59 are both hexagonal heads. Therefore, the docking shaft 53 can transmit torque to the valve core 2 via the connecting rod 54, thereby driving the valve core 2 to rotate.

[0202] Specifically, the shaft sleeve 55 can be fixedly mounted on the mobile heat-insulating silo. During disassembly, the shaft sleeve 55 can be first removed from the mobile heat-insulating silo, and then the connecting rod 54 can be removed. Finally, the abutment nut 43 can be unscrewed, and the spring and pressure plate 41 can be removed. After that, the valve core 2 can be removed for cleaning. After cleaning, the installation sequence is the opposite of the disassembly sequence. It can be seen that the disassembly and installation of the valve core 2 in this embodiment is very convenient, and thus easy to clean and replace.

[0203] In summary, under the action of the clamping mechanism, the valve core 2 is compressed within the mounting tapered hole 5, causing the conical surface portion 6 of the valve core 2 to contact the inner wall of the mounting tapered hole 5, thereby achieving a seal. Rotating the valve core 2 can drive the guide hole 7 in the valve core 2 to rotate. When the guide hole 7 is rotated to align with the feed hole 3 and the discharge hole 4, respectively, the feed hole 3 can communicate with the discharge hole 4 through the guide hole 7. At this time, material can be discharged through the feed hole 3, the guide hole 7, and the discharge hole 4 in sequence, indicating an open state. When the guide hole 7 is rotated to be offset from the feed hole 3 and the discharge hole 4, the feed hole 3 is disconnected from the discharge hole 4, and material cannot be discharged, indicating a closed state. Furthermore, the opening degree can be controlled by controlling the rotation angle of the valve core 2, and the switching process is short, enabling rapid switching. The heat-conducting medium can flow through the heat-insulating heating flow channel in the valve body 1, and the heat of the heat-conducting medium can be transferred to the valve body 1 to heat the valve body 1. Then, the valve body 1 heats the valve core 2 through heat transfer, thereby realizing the heat-insulating and heating function of the valve body 1 and the valve core 2, improving the heat-insulating and heating effect. When the material is discharged through the feed hole 3, the guide hole 7 and the discharge hole 4, it will not cool and solidify due to the temperature drop, thus avoiding the problem of material cooling and solidification and then clogging after long-term use. In addition, even if the conical surface part 6 on the valve core 2 has a certain degree of wear after long-term use, the clamping mechanism can apply force to drive the valve core 2 to be pressed against the mounting conical hole 5, thereby keeping the conical surface part 6 on the valve core 2 close to the inner wall of the mounting conical hole 5, thereby ensuring the sealing performance, avoiding leakage caused by wear of the valve core 2, reducing the risk of leakage, and greatly extending the service life, making it strong and durable.

[0204] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention.
