Description

Technical Field

[0001] This invention belongs to the field of cold and heat source supply technology, specifically relating to a cold and heat source supply device for a production line and its control method. Background Technology

[0002] In industrial production, equipment for supplying cold and heat sources is frequently used, such as in the production of vitamins. Different steps in a series of processes generate varying demands for cold and heat supply. However, existing cold and heat supply equipment requires waiting for the heat exchanger to heat up or cool down when switching between cold and heat sources. Switching from cold to heat requires the heat exchanger to gradually raise its temperature before supplying heat; conversely, switching from heat to cold requires the heat exchanger to cool down before supplying cold. This waiting time is relatively long, and the equipment cannot meet the temperature demands of different steps in a timely manner, affecting reaction efficiency and effectiveness.

[0020] Preferred embodiment.

[0021] This embodiment provides a production line heat and cold source supply device, including a heat source supply mechanism, a cold source supply mechanism, and a heat and cold conveying mechanism. The heat and cold conveying mechanism includes a first fan 300, a first switching valve, and a second switching valve. One end of the first switching valve is connected to the first fan 300 through a conveying pipe. The heat source supply mechanism includes a first heat source housing 400. The inlet end of the first heat source housing 400 is connected to the other end of the first switching valve through a conveying pipe, and the outlet end of the first heat source housing 400 is connected to one end of the second switching valve through a conveying pipe. The cold source supply mechanism includes a first cold source housing 500. The inlet end of the first cold source housing 500 is connected to another end of the first switching valve through a conveying pipe, and the outlet end of the first cold source housing 500 is connected to the other end of the second switching valve through a conveying pipe. The other end of the second switching valve is connected to the production line heat and cold source supply pipeline. The first switching valve includes a first valve body 100, a first valve plate 150, and a first driving mechanism. The first valve plate 150 is disposed inside the first valve body 100 via a first rotating shaft 140. A first adjusting rod is connected to the outside of the first rotating shaft 140. The first driving mechanism is connected to the first adjusting rod. A first connection port 110 is provided at the left end of the first valve body 100. A second connection port 120 is provided at the right end of the first valve body 100. A third connection port 130 is provided at the upper end of the first valve body 100. The first valve plate 150 is matched with the second connection port 120 and the third connection port 130. The second switching valve includes a second valve body 200, a second valve plate 250, and a second drive mechanism. The second valve plate 250 is disposed inside the second valve body 200 via a second rotating shaft 240. A second adjusting rod is connected to the outside of the second rotating shaft 240. The second drive mechanism is connected to the second adjusting rod. A fourth connection port 210 is provided at the left end of the second valve body 200. A fifth connection port 220 is provided at the right end of the first valve body 100. A sixth connection port 230 is provided at the upper end of the first valve body 100. The first valve plate 150 is matched with the fourth connection port 210 and the sixth connection port 230.

[0022] Specifically, when cold air is required on the production line, the first valve plate 150 closes the second connection port 120, and the second valve plate 250 closes the fourth connection port 210; when hot air is required on the production line, the first valve plate 150 closes the third connection port 130, and the second valve plate 250 closes the sixth connection port 230. That is, when the first fan 300 delivers air, it can immediately select to supply hot air or cold air, and it needs to wait for the temperature of the hot air to drop before supplying cold air, or for the temperature of the cold air to rise before supplying hot air.

[0023] Furthermore, the first driving mechanism includes a first driving motor and a first support frame. The first support frame is disposed at the front end of the first valve body 100, and the first driving motor is disposed at the upper end of the first support frame. The front end of the first adjusting rod passes through the first valve body 100 and is provided with a first connecting part. The first connecting part is drivenly connected to the first driving motor. The front end of the third connecting port 130 is provided with a first anti-reverse component, which matches the first connecting part. The rear end of the first adjusting rod passes through the first valve body 100 and is provided with a second connecting part 610. The rear end of the second connecting port 120 is provided with a second anti-reverse component, which matches the second connecting part 610.

[0024] The first drive motor drives the rotation of the first connecting part, which in turn drives the rotation of the first valve plate 150, thereby closing the second connecting port 120 or the third connecting port 130. This ensures that the first switching valve only opens one port, allowing for the selection of either hot or cold air supply.

[0025] Furthermore, the first anti-reverse component includes a first slider, a first adjusting block 670, and a plurality of first baffles 170. The first slider is disposed at the front end of the first valve body 100. The first adjusting block 670 is provided with a first slide rail, and the first slider matches the first slide rail. The left end of the first baffle 170 is provided with a first shaft 171. The first baffles 170 are stacked end to end in the first connection port 110. The front end of the first shaft 171 passes through the first connection port 110 and is provided with a first limiting plate. The first adjusting block 670 is provided with a first limiting block, and the first limiting block matches the first limiting plate. The first adjusting block 670 is provided with a first rack, and the first connecting part is provided with a first gear. The first rack matches the first gear. The first gear rotates 1 / 4 turn, and the travel distance of the first rack is not greater than the width of the first limiting plate. The rotation of the first connecting part drives the rotation of the first gear. Through the interaction of the first gear and the first rack, the first adjusting block 670 moves. When the first valve plate 150 covers the third connecting port 130, the right end of the first baffle 170 rests on the upper left end of the right-side first baffle 170, while the first limiting block presses against the upper end of the first limiting plate, thus restricting the first limiting plate and further ensuring sealing and backflow prevention. The stroke distance of the first rack is not greater than the width of the first limiting plate. That is, when the third connecting port 130 is open, the first limiting block is at the left end of the first shaft 171. When the first fan 300 delivers air, it can blow up the first baffle 170, and the first limiting block also limits rotation, preventing the first baffle 170 from overturning and becoming difficult to turn back.

[0026] The second anti-reverse assembly includes a second slider, a second adjusting block 640, and several second baffles 160. The second slider is located at the rear end of the first valve body 100. The second adjusting block 640 is provided with a second slide rail 650, and the second slider matches the second slide rail 650. The upper end of the second baffle 160 is provided with a second shaft 161. The second baffles 160 are stacked end to end in the second connection port 120. The rear end of the second shaft 161 passes through the second connection port 120 and is provided with a second limiting plate 162. The second adjusting block 640 is provided with a second limiting block 630, and the second limiting block 630 matches the second limiting plate 162. The second adjusting block 640 is provided with a second rack 660, and the second connecting part 610 is provided with a second gear 620, and the second rack 660 matches the second gear 620. The second gear 620 rotates 1 / 4 turn, and the stroke distance of the second rack 660 is not greater than the width of the second limiting plate 162.

[0027] When the second connection port 120 is closed, the second limiting block 630 can press on the second limiting plate 162, and in conjunction with the limiting structure between the second baffles 160, ensure the sealing and anti-reverse effect of the second connection port 120.

[0028] Furthermore, the second drive mechanism includes a second drive motor and a second support frame. The second support frame is located at the front end of the second valve body 200, and the second drive motor is located at the upper end of the second support frame. The second drive motor is driven and connected to the second adjusting rod. The rear end of the second adjusting rod passes through the second valve body 200 and is provided with a third connecting part. The fifth connecting port 220 is provided with a third anti-reverse assembly. The third anti-reverse assembly includes a plurality of third baffles 260. The upper end of each third baffle 260 is provided with a third shaft 261. The third baffles 260 are stacked end to end in the fifth connecting port 220. The third baffles 260 located in the fifth connecting port 220 serve to prevent backflow of cold / heat sources within the production line.

[0029] Furthermore, the heat source supply mechanism includes a steam supply pipe 410, a first steam inlet pipe 420, and a first booster pump 440. The upper end of the first steam inlet pipe 420 is provided with several first connecting branch pipes 423. The first heat source housing 400 is provided with several first circulation pipes. The first connecting branch pipes 423 are connected to the first circulation pipes one-to-one. The lower end of the steam supply pipe 410 is provided with a second connecting branch pipe 411 and a third connecting branch pipe 412. The lower end of the first steam inlet pipe 420 is provided with a fourth connecting branch pipe 421 and a fifth connecting branch pipe. 422, the second connecting branch pipe 411 and the fourth connecting branch pipe 421 are respectively connected to the two ends of the first booster pump 440, and the third connecting branch pipe 412 and the fifth connecting branch pipe 422 are connected through the first manual valve 430; the cold source supply mechanism includes a cooling water supply pipe 510 and a cooling water return pipe 520, and a plurality of second circulation pipes are provided in the first cold source box 500. The lower end of the second circulation pipe is connected to the cooling water supply pipe 510, and the upper end of the second circulation pipe is connected to the cooling water return pipe 520.

[0030] A method for controlling a cold and heat source supply device in a production line includes the following steps: Step S1: Steam is supplied to the first circulation pipe through the steam supply pipe 410, and cooling water is supplied to the second circulation pipe through the cooling water supply pipe 510 and the cooling water return pipe 520. The first fan 300 is turned on to blow air towards the first switching valve. When cold air is required on the production line, the first valve plate 150 closes the second connection port 120, and the second valve plate 250 closes the fourth connection port 210. When hot air is required on the production line, the first valve plate 150 closes the third connection port 130, and the second valve plate 250 closes the sixth connection port 230. That is, the air blown out by the first fan 300 is directly cooled or heated before entering the production line, without waiting for the temperature to rise or fall, which improves efficiency, provides more timely supply, and has a better reaction effect.

[0031] Step S2: When cold air is required for production, the first drive motor drives the first valve plate 150 to flip downwards, blocking the second connection port 120. The second drive motor drives the second flap to flip downwards, blocking the fourth connection port 210. The first fan 300 blows air into the first cold source box 500. After being cooled by the second circulation pipe, the cold air is blown onto the production line. Before switching from supplying hot air to supplying cold air, the cooling water supply can be confirmed in advance to ensure that the cold air can be quickly switched to hot air supply without waiting for the heat to slowly decrease.

[0032] Step S3: When hot air is required for production, the first drive motor drives the first valve plate 150 to flip upwards, blocking the third connection port 130. The second drive motor drives the second flapper to flip upwards, blocking the sixth connection port 230. The first fan 300 blows air into the first heat source box 400. After being heated by the first circulation pipe, the hot air is blown onto the production line. Before switching from supplying cold air to supplying hot air, the steam supply can be confirmed in advance to ensure the heat supply of the first heat source box 400, thereby ensuring a rapid switch from cold air to hot air supply without waiting for the heat to gradually increase.

[0033] It is worth mentioning that the technical features of the first booster pump 440 and the second circulation pipe involved in this patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be adopted by conventional choices in the field and should not be regarded as the inventive point of this patent. This patent will not be further elaborated in detail.

[0034] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
