Description

Technical Field

[0001] The utility model relates to the technical field of gate valves, in particular to a gate valve for high-temperature aerobic fermentation of kitchen waste. Background Art

[0002] The gate valve, also known as the knife-type gate valve, is a valve in which the gate and the valve seat are always in close contact and sealing. A channel is opened on the gate. The gate and the channel are completely separated and matched by opening and closing the gate, and the movement of the gate is used to control the flow of the medium.

[0003] The patent "A Slot Valve" with an existing application number of 202322022180.0 discloses that "the drive assembly 6 drives the valve core 4 to move in the extension direction of the valve plate 2 through the screw 62. When the valve core 4 moves to the second through hole 34 of the housing 3, the sealing ring in the dovetail groove 41 on its surface seals the gap between the surface of one side of the valve core 4 and the inner wall of the housing 3 to achieve a sealed connection. The other side of the valve core 4 is supported on the inner wall of the other side of the housing 3 to clamp the sealing ring; at this time, the slot valve is in a closed state, and the medium cannot flow in the first through hole 11; when the drive assembly 6 drives the valve core 4 to disengage from the second through hole 34, the orifice of the second through hole 34 is connected to the hole wall of the first through hole 11 to form a through medium flow passage, and the slot valve is in an open state." In this technical solution, the opening and closing of the valve core depends on the drive assembly and the screw rod. However, the screw rod is worn and the screw rod precision is impaired. Although the valve core can still play a closing role, there is indeed a problem that the valve core is not fully in place. Utility Model Content

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

[0029] See also Figure 1-4The utility model provides a technical solution: a plug valve for high temperature aerobic fermentation of kitchen waste, comprising a plug frame 1, an I-beam is fixedly arranged in the middle of the plug frame 1, a hollow through groove on one side of the plug frame 1 is respectively connected with a feed inlet 18 and a discharge port 19, a plug frame 1 is slidably arranged with a plug plate 10 in the horizontal direction, a plug guide rail 8 which is slidably matched with the plug plate 10 is fixedly connected on both sides of the plug frame 1, and a plug guide rail 2 9 which is adapted to the plug plate 10 is provided at the other end of the plug frame 1, and the plug plate 10 passes through I-beam, a sealing assembly is provided on the I-beam to seal the insertion point of the plug plate 10, a screw lifting motor 3 is fixedly installed at one end of the plug plate frame 1, the output shaft of the screw lifting motor 3 is connected to the screw 14, one end of the screw 14 is fixedly connected to the plug plate 10, the plug plate frame 1 is fixedly connected to the photoelectric sensor 11 and the photoelectric sensor 2 12 through the bracket 13 on the side close to and away from the I-beam, and the end of the plug plate 10 close to the screw 14 is fixedly connected to the baffle 15 that acts on the photoelectric sensor. The screw lifting motor 3 drives the screw 14 to rotate, pushes the plug plate 10 to open or close the left channel port, and the end of the plug plate 10 is inserted into the plug plate guide rail 2 9. During the movement of the plug board 10, the baffle 15 moves synchronously therewith, and the infrared rays emitted by the photoelectric sensor 11 are blocked by the baffle 15, and a signal is sent to the processor. After the processor processes the signal, the controller controls the drive motor 3 to stop. Due to the structural design and pre-debugging, the plug board 10 has completely closed the left channel at this time. Similarly, when the plug board 10 moves to the right, the baffle 15 blocks the infrared rays emitted by the photoelectric sensor 2 12, and the screw rod lifting motor 3 stops under the signal drive, and the plug board 10 has completely opened the left channel at this time. In this embodiment, the baffle 15 is fixed on the plug board 10, and the screw rod lifting motor 3 stops driving only when the plug board 10 is closed in place. Even if the accuracy of the screw rod 14 is damaged, it does not affect the drive plug board 10 to close in place, ensuring that the left channel can be fully opened or closed.

[0030] Specifically, Figure 2 and Figure 4 As shown, the sealing assembly includes an inner sealing block 7, a sealing packing 16 and a sealing strip 17. Two groups of inner sealing blocks 7 are arranged near the side of the plug-in board guide rail 29. The two groups of inner sealing blocks 7 are fixedly connected to the I-beam and arranged on the upper and lower sides of the plug-in board 10. The sealing packing 16 is arranged near the side of the screw rod 14. The sealing packing 16 contacts the plug-in board 10. The sealing packing 16 is provided with an L-shaped sealing strip 17 in contact. Two groups of screws 15 and screws 26 for fixing the sealing strip 17 are fixedly connected to the I-beam. The screws 15 abut against the horizontal end of the sealing strip 17, and the screws 26 abut against the vertical end of the sealing strip 17. The inner sealing block 7 and the sealing packing 16 play a sealing role together. The sealing packing 16 is pressed on the plug-in board 10 through the sealing strip 17. When the plug-in board 10 is in use, the damaged sealing packing 16 can be replaced by loosening the screws.

[0031] Specifically, Figure 1 and Figure 2 As shown, the upper and lower sides of the plugboard frame 1 are fixedly connected with support plates 2 near the screw rod 14, and the support plate 2 located on the upper side of the plugboard frame 1 is provided with a wire hole 201, and the cable passes through the wire hole 201 to be connected to the photoelectric sensor.

[0032] Specifically, Figure 2 As shown, one end of the plugboard frame 1 close to the screw lifting motor 3 is fixedly connected with a screw protection sleeve 4 sleeved on the outside of the screw 14 to protect the screw 14 and increase the service life of the screw 14.

[0033] Furthermore, the present embodiment is suitable for closing / opening the upper feed port of the high-temperature aerobic fermentation bin for food waste, which acts as a material gate and blocks the overflow of high-temperature gas, ensuring the sealing and heat preservation of the interface of the fermentation bin; the plug-in guide rails, plug-in plates and other components in contact with the material or the inside of the fermentation bin are all made of polymer materials (PTFE), which are corrosion-resistant, acid-resistant, high-temperature-resistant, have low thermal conductivity, and have self-lubricating properties.

[0034] Working principle: when in use, the screw lifting motor 3 drives the screw 14 to rotate, pushing the plug board 10 to open or close the left channel opening. The end of the plug board 10 is inserted into the plug board guide rail 2 9. During the movement of the plug board 10, the baffle 15 moves synchronously therewith, and the infrared ray emitted by the photoelectric sensor 11 is blocked by the baffle 15, and a signal is sent to the processor. After the processor processes the signal, the controller controls the drive motor 3 to stop. Due to the structural design and pre-debugging, the plug board 10 has completely closed the left channel opening at this time. Similarly, when the plug board 10 moves to the right, the baffle 15 blocks the infrared ray emitted by the photoelectric sensor 2 12. The screw lifting motor 3 stops under the signal drive, and the plug board 10 has completely opened the left channel opening at this time. Among them, since the baffle 15 is fixed on the plug board 10, the screw lifting machine 3 will only stop driving when the plug board 10 is closed in place. Even if the accuracy of the screw rod 14 is damaged, it will not affect the driving plug board 10 to close in place, thereby ensuring that the left channel opening can be completely opened or closed.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
