Automated cleaning WDG production line

Abstract

This utility model relates to the field of pesticide production equipment technology, specifically an automatic cleaning WDG production line, including a mixing tank, a top cover, and a lifting assembly. Material enters the mixing tank through a feeding pipe, and a motor drives a vertical pipe and a stirring rod to complete the mixing. After mixing, the material is discharged through a discharge pipe. During cleaning, the lifting assembly raises the top cover, disassembles the protective shell, connects an external water supply device to a transfer pipe, and sprays cleaning fluid from the nozzles. Simultaneously, the vertical pipe rotates to achieve all-round rinsing of the inner wall of the mixing tank. The lifting assembly uses a cylinder, the motor uses a servo motor, and the limit seat uses a positioning bearing to ensure the stability of the vertical rod. The removable protective shell prevents nozzle clogging. This production line achieves automated cleaning, solving the problems of low efficiency and incomplete cleaning in traditional manual cleaning, ensuring product quality, improving cleaning efficiency, and reducing labor intensity and safety hazards.

Description

Technical Field

[0001] This utility model relates to the field of pesticide production equipment technology, specifically to an automatic cleaning WDG production line. Background Technology

[0002] WDG is a pesticide formulation composed of active ingredient, inert filler, and adjuvants (such as dispersants, wetting agents, and suspending agents). It can rapidly disintegrate and disperse in water to form a highly dispersed suspension, and is widely used in pesticide manufacturing.

[0003] In the WDG production line, the mixer is a crucial component. It is mainly used to thoroughly and evenly mix various raw materials required for WDG production, such as active ingredients, inert fillers, dispersants, wetting agents, and suspending agents, according to precise proportions. After use, the mixer needs to be cleaned. Traditional manual cleaning methods are inefficient, incomplete, and pose safety hazards. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an automated cleaning WDG production line.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic cleaning WDG production line, including a mixing tank, a top cover at the upper end of the mixing tank, a discharge pipe at the lower end of the mixing tank, a valve on the discharge pipe, a feeding pipe on the top cover, and multiple lifting components symmetrically arranged on both sides of the mixing tank, with lifting rods connecting the two sides of the top cover at the output end of the lifting components.

[0008] The top cover has a limiting seat in the middle, and a vertical tube is vertically rotatably mounted on the limiting seat. A stirring rod is mounted at the lower end of the vertical tube. Two liquid outlet pipes are symmetrically arranged at the bottom of the vertical tube. A limiting frame is mounted on one side of the liquid outlet pipe. Multiple nozzles are mounted inside the limiting frame. The nozzles, liquid outlet pipes and vertical tubes are connected. A driven gear is mounted at the top of the vertical tube above the top cover. A transfer pipe is rotatably mounted at the top of the vertical tube. A motor is mounted at the upper end of the top cover. A drive gear that meshes with the driven gear is mounted at the output end of the motor.

[0009] Furthermore, the improvement of this utility model is that the lifting component is a cylinder and the motor is a servo motor.

[0010] To improve the stability of the vertical tube during use, the present invention includes an improvement in which a positioning bearing is embedded inside the limiting seat, the vertical tube passes through the positioning bearing, and is rotatably connected to the limiting seat.

[0011] Furthermore, an improvement of this utility model is that the adapter pipe is fixed above the top cover by a support rod, and the top end of the vertical pipe is inserted into the interior of the adapter pipe and rotatably connected to the adapter pipe through a sealed bearing.

[0012] To prevent the nozzles from clogging, the present invention includes the following improvements: the limiting frame is equipped with a detachable protective shell, and multiple nozzles are located inside the protective shell. Multiple slots are symmetrically arranged on the inner wall of the limiting frame, and multiple cavities are provided on both sides of the protective shell. Springs are installed inside the cavities, with one end of the spring fixed inside the cavity and the other end provided with a locking block that cooperates with the slot.

[0013] Material is added through the feeding pipe and discharged through the discharge pipe. The motor is started, and the driving gear rotates with the driven gear, so that the vertical pipe carries the stirring rod to stir the mixture in the mixing tank.

[0014] After the material is discharged, start the lifting assembly to raise the top cover, then pull the protective shell to disengage the locking block from the slot, thereby removing the protective shell from the limit frame and exposing multiple nozzles. Connect the external water supply equipment to the transfer pipe through the conduit, start the water supply equipment, and spray the cleaning fluid at multiple nozzles. As the vertical pipe rotates, the inner wall of the mixing tank can be rinsed more thoroughly.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an automated cleaning WDG production line, which has the following advantages:

[0017] This design revolutionizes the inefficient traditional manual cleaning method by automating the cleaning of mixing tanks. The cleaning process requires minimal human intervention; simple operation of the equipment switches quickly completes the task, significantly improving efficiency and reducing worker workload.

[0018] Driven by the vertical pipe, the nozzle rotates and rinses, and with the high-pressure water flow, it can reach every corner of the mixing tank, effectively removing material residues adhering to the tank wall, avoiding cross-contamination of materials due to incomplete cleaning, and ensuring the quality stability of the next batch of products.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 The present invention relates to an automatic cleaning WDG production line, comprising a mixing tank 1, a top cover 2 at the upper end of the mixing tank 1, a discharge pipe 8 at the lower end of the mixing tank 1, a valve on the discharge pipe 8, a feeding pipe 7 on the top cover 2, and multiple lifting components 3 symmetrically arranged on both sides of the mixing tank 1, with lifting rods 4 connecting the two sides of the top cover 2 at the output end of the lifting components 3.

[0026] The top cover 2 has a limiting seat 10 in the middle part, and a vertical tube 9 is vertically rotatably mounted on the limiting seat 10. A stirring rod 22 is mounted at the lower end of the vertical tube 9. Two liquid outlet pipes 15 are symmetrically arranged at the bottom of the vertical tube 9. A limiting frame 16 is mounted on one side of the liquid outlet pipe 15. Multiple nozzles 17 are mounted inside the limiting frame 16. The nozzles 17, liquid outlet pipes 15 and vertical tube 9 are connected. A driven gear 13 is mounted at the top of the vertical tube 9 above the top cover 2. A transfer pipe 11 is rotatably mounted at the top of the vertical tube 9. A motor 23 is mounted at the upper end of the top cover 2. A drive gear 14 that meshes with the driven gear 13 is mounted at the output end of the motor 23.

[0027] The lifting assembly 3 is a cylinder, and the motor 23 is a servo motor.

[0028] The adapter pipe 11 is fixed above the top cover 2 by the support rod 12, and the top end of the vertical pipe 9 is inserted into the interior of the adapter pipe 11 and rotatably connected to the adapter pipe 11 through a sealed bearing.

[0029] The limiting frame 16 is provided with a detachable protective shell 19, and multiple nozzles 17 are located inside the protective shell 19. Multiple slots 18 are symmetrically arranged on the inner wall of the limiting frame 16. Multiple cavities 20 are provided on both sides of the protective shell 19. Springs are provided inside the cavities 20. One end of the spring is fixed inside the cavity 20, and the other end is provided with a locking block 21 that cooperates with the slot 18.

[0030] During the operation of the automated WDG production line, the material enters the mixing tank 1 through the feeding pipe 7 on the top cover 2. After feeding is completed, the motor 23 is turned on. The drive gear 14 at the output end of the motor 23 drives the driven gear 13 that meshes with it to rotate, thereby driving the vertical pipe 9 to rotate. The stirring rod 22 connected to the lower end of the vertical pipe 9 rotates accordingly, thoroughly mixing the raw materials, fillers, and various additives in the tank to ensure uniform material distribution. After mixing is completed, the valve on the discharge pipe 8 is opened, and the mixed material is discharged from the discharge pipe 8.

[0031] When a production task is completed and the mixing tank 1 needs to be cleaned, the lifting components 3 on both sides of the mixing tank 1 are activated to slowly raise the top cover 2, leaving space for subsequent cleaning operations.

[0032] Subsequently, the protective shell 19 on the limit frame 16 is pulled, and the springs in the cavities 20 on both sides of the protective shell 19 are compressed, and the locking block 21 is disengaged from the locking slot 18, thereby realizing the disassembly of the protective shell 19 on the limit frame 16, so that the nozzle 17 is fully exposed.

[0033] Next, connect the external water supply equipment to the transfer pipe 11 through a conduit, turn on the water supply equipment, and the cleaning fluid will be sprayed out at high speed from the nozzle 17 through the transfer pipe 11, the vertical pipe 9, and the outlet pipe 15.

[0034] At the same time, the motor 23 starts again, and the drive gear 14 drives the driven gear 13, causing the vertical pipe 9 to rotate continuously. The nozzle 17 also rotates accordingly, and thoroughly and completely washes every corner of the inner wall of the mixing tank 1 to ensure the cleaning effect.

[0035] The structure is ingenious and the operation is flexible: the lifting component 3 can lift the top cover 2 flexibly, which is convenient for inspection, maintenance and disassembly of the protective shell 19 inside the mixing tank 1; the detachable protective shell 19 design can not only protect the nozzle 17 during the production process and prevent material blockage, but also facilitate quick disassembly during cleaning. It is simple to operate and highly practical.

[0036] The limiting seat 10 is internally fitted with a positioning bearing, and the vertical tube 9 passes through the positioning bearing and is rotatably connected to the limiting seat 10.

[0037] The limiting seat 10 is inlaid with a positioning bearing, and the vertical tube 9 and the transfer tube 11 are rotatably connected by a sealed bearing. This design effectively improves the stability and sealing of the vertical tube 9 when it rotates, reduces wear during equipment operation, extends the service life of the equipment, and reduces the maintenance cost of the equipment.

[0038] Automated cleaning avoids direct contact between workers and cleaning solutions and residual materials, reducing potential safety hazards associated with manual cleaning and ensuring the health of operators and production safety.

[0039] Cylinder model: RA / 8032 / N2 / 500 (NORGREN) 4.

[0040] Motor Model 23: NORD brand servo motors can be selected (the specific model needs to be determined based on actual power, torque and other requirements).

[0041] Printhead Model 17: FV020 Bolondi Printhead 17XM Series 2.

[0042] Water supply equipment model: Grundfos CR series stainless steel multistage centrifugal pumps can be selected.
