[0002] Crude gamma-decyl lactone refers to a mixture containing the target product gamma-decyl lactone, but still containing unreacted raw materials, byproducts, solvents, and small amounts of impurities, obtained after the initial synthesis reaction in the preparation of crude gamma-decyl lactone. In the preparation of crude gamma-decyl lactone, the input of raw materials has a significant impact on the final product quality and production efficiency.

[0003] However, existing feeding devices have many problems in actual use. On the one hand, raw materials often need to be mixed before feeding, but the stirring structure of traditional devices is simple and cannot achieve sufficient and uniform mixing of raw materials, resulting in insufficient contact between different raw materials, affecting the subsequent reaction, reducing reaction efficiency and crude product yield. On the other hand, after the equipment is used, raw materials are easy to remain on the inner wall of the feeding cylinder and related components. Existing devices lack effective cleaning structures. Manual cleaning is not only cumbersome, time-consuming and labor-intensive, but also difficult to completely remove residual raw materials. The residual raw materials will corrode the equipment and shorten its service life. At the same time, the filter media used for filtration is inconvenient to replace, and the filtration effect will decrease after long-term use, which will also affect the purity of the raw materials.

Example

[0018] Based on the problem of insufficient raw material mixing in existing feeding devices leading to low reaction efficiency and crude product yield, this invention provides a preferred embodiment of a feeding device for the preparation of crude propyldecyl lactone, for example... Figure 1-4 As shown: A dispensing device for preparing crude gamma-decyl lactone includes a dispensing cylinder 1, a controller 3 disposed on the front of the dispensing cylinder 1, support legs 2 evenly distributed on the outer wall of the dispensing cylinder 1, and a dispensing assembly 4 disposed on the top of the dispensing cylinder 1.

The mixing component 41 includes: a mixing cylinder 411 connected to the top of the dispensing cylinder 1; a motor 412 disposed on the top of the mixing cylinder 411; and a feed hopper 419 connected to one side of the mixing cylinder 411. A stirring shaft 413 is disposed at the output end of the motor 412, and the other end of the stirring shaft 413 movably penetrates the top of the outer wall of the mixing cylinder 411 and the mixing cylinder 411. The inner wall of the mixing cylinder 411 extends to the top and into the inner wall of the feeding cylinder 1. Mixing blades 414 are equidistantly installed on the outer circumference of the mixing shaft 413. A connecting ring 415 is fixedly sleeved on the bottom of the outer wall of the mixing shaft 413. Connecting rods 416 are fixedly installed on both sides of the connecting ring 415. A scraper 417 is fixedly installed on the other end of the connecting rod 416. The scraper 417 contacts the inner wall of the feeding cylinder 1. A screening screen 418 is fixedly installed inside the mixing cylinder 411. The screening screen 418 is movably sleeved on the outer wall of the mixing shaft 413. A locking opening is opened on one side of the outer wall of the feeding hopper 419. A sliding rod 4111 is fixedly installed on both sides of the inner wall of the feeding hopper 419. An mounting plate 4112 is slidably connected to the outer wall of the sliding rod 4111. A locking groove is provided on the opposite side of the mounting plate 4112. The mounting plate 4112 is connected to the filter plate 4113 through the locking groove. A locking plate 4114 is fixedly installed on the outer side of the mounting plate 4112. The locking plate 4114 is connected to the feed hopper 419 through the locking port. A handle 4115 is fixedly installed on the other side of the locking plate 4114. Slide rails 4116 are fixedly installed on both sides of the outer wall of the feed hopper 419. The slide rails 4116 are slidably connected to the top cover 4118 through the slide rod 4117. A handle 4119 is fixedly installed on one side of the top cover 4118.

[0019] Furthermore, in this embodiment, the top cover 4118 is opened by the handle 4119 along the slide rail 4116 and the slide rod 4117, and the raw material is fed into the feed hopper 419. The raw material is first filtered by the filter plate 4113 on the mounting plate 4112 to remove large particles of impurities. The mounting plate 4112 can be pulled out along the slide rod 4111 by the handle 4115 to facilitate cleaning or replacement of the filter plate 4113. The filtered raw material enters the mixing cylinder 411. Then, the motor 412 is started, and its output end drives the stirring shaft 413 to rotate. The mixing blades 414 on the outer wall of the stirring shaft 413 stir and mix the raw material. At the same time, the raw material is screened again by the screening screen 418 to ensure that the raw material particles are uniform. Example

[0020] Based on Example 1, a preferred embodiment of the feeding device for preparing crude propyl decyl lactone provided by this utility model is as follows: Figure 1-4 As shown: The cleaning component 42 includes: a connecting box 421, fixedly installed on the top of the dispensing cylinder 1; a fixing plate 423, fixedly installed on one side of the dispensing cylinder 1; a dispensing pipe 429, connected to the bottom of the dispensing cylinder 1; nozzles 422 are equidistantly connected to the bottom circumference of the connecting box 421, the other end of the nozzles 422 penetrates the top of the outer wall of the dispensing cylinder 1 and extends to the top of the inner wall of the dispensing cylinder 1; a storage tank 424 is fixedly installed on the top of the fixing plate 423, an inlet pipe 428 is connected to the top of the storage tank 424, a water outlet pipe 425 is connected to the top of the connecting box 421, a pump 426 is connected to the other end of the water outlet pipe 425, a suction pipe 427 is connected to the input end of the pump 426, the other end of the suction pipe 427 penetrates the top of the storage tank 424 and extends to the interior of the storage tank 424, a control valve 4211 is provided in the middle of the dispensing pipe 429, and an electromagnetic flow meter 4212 is provided on the inner wall of the dispensing pipe 429.

[0021] Furthermore, in this embodiment, by opening the control valve 4211 at the middle of the delivery pipe 429, the raw material flows out through the delivery pipe 429. The electromagnetic flowmeter 4212 monitors the flow rate in real time and feeds the data back to the controller 3. The pump 426 starts and draws the cleaning liquid from the storage tank 424 through the extraction pipe 427. The cleaning liquid is then transported to the connecting box 421 through the water outlet pipe 425 and sprayed into the delivery cylinder 1 through the nozzle 422 at the bottom of the connecting box 421 to rinse the cylinder wall and internal components. The waste liquid after rinsing can be discharged through the delivery pipe 429, and the storage tank 424 can be replenished with cleaning liquid through the inlet pipe 428.

[0022] During operation, after the equipment is started, the controller 3 coordinates the operation of each component. First, preparations are made before raw material feeding. The operator opens the top cover 4118 via handle 4119 along slide rail 4116 and slide bar 4117, feeding the raw material into the feed hopper 419. The raw material first undergoes preliminary filtration through the filter plate 4113 on the mounting plate 4112 to remove large particles. The mounting plate 4112 can be pulled out along slide bar 4111 via handle 4115 for easy cleaning or replacement of the filter plate 4113. The filtered raw material enters the mixing cylinder 411. Next, the motor 412 starts, and its output drives the stirring shaft 413 to rotate. The mixing blades 414 on the outer wall of the stirring shaft 413 stir and mix the raw material. Simultaneously, the raw material passes through the screening screen 418 for further screening to ensure uniform particle size. The mixed raw material then enters the feeding cylinder 1. The connecting ring 415 at the end rotates with the shaft, driving the scraper 417 to rotate via the connecting rod 416. The scraper 417 contacts the inner wall of the feeding cylinder 1, preventing raw materials from remaining on the cylinder wall. When raw materials need to be fed into the reactor, the control valve 4211 at the middle end of the feeding pipe 429 is opened, and the raw materials flow out through the feeding pipe 429. The electromagnetic flowmeter 4212 monitors the flow rate in real time and feeds the data back to the controller 3 to ensure accurate feeding. After the equipment is used, it can be cleaned through the cleaning component 42. The pump 426 is started, and the cleaning liquid is drawn from the storage tank 424 through the liquid extraction pipe 427 and transported to the connecting box 421 through the water outlet pipe 425. Then, it is sprayed into the inside of the feeding cylinder 1 through the nozzle 422 at the bottom of the connecting box 421 to rinse the cylinder wall and internal components. The waste liquid after rinsing can be discharged through the feeding pipe 429, and the storage tank 424 can be replenished with cleaning liquid through the liquid inlet pipe 428.
