Description

Technical Field

[0001] This utility model relates to the technical field of pesticide suspension production equipment, and in particular to a feed head for a microcapsule suspension aeration tank. Background Technology

[0002] Microencapsulated suspensions, as one of the four major water-based pesticide formulations, offer greater advantages in extending the effective period and reducing application costs compared to conventional water-based formulations. The production process for this formulation begins with encapsulation. However, during this process, air bubbles are generated due to the chemical reaction. If these bubbles are not removed, the filled bottles will either bulge and deform, or the pesticide will leak from the bottle opening, contaminating the bottle and label and affecting its appearance. To address this issue, the applicant designed a specialized aeration device that uses an aeration tank to aerate the encapsulated pesticide solution, and applied for a utility model patent (CN201999718U) based on this design. Although the aforementioned device automates the aeration process, in actual production, the aeration process still requires a considerable amount of time. The aeration time for a single batch of pesticide solution often ranges from 10 (summer) to 20 days (winter), resulting in low production efficiency, high energy consumption, and high production costs. Furthermore, it is increasingly difficult to meet the rapidly growing market demand for microencapsulated suspension products. Utility Model Content

[0003] To address the problems in the background technology, this utility model provides a feed head for a microcapsule suspension aeration tank, which solves the problem of how to increase the chance of gas carrying bubbles in the material to escape, shorten the aeration time of the aeration tank, improve production efficiency, and reduce production costs.

[0004] To achieve the purpose of this utility model, this utility model provides a feed head for a microcapsule suspension aeration tank. Its innovation lies in: including a pipe connector and a distribution tower; the pipe connector is positioned above the distribution tower; the distribution tower includes three distribution discs arranged coaxially along a vertical axis, with the maximum diameter of the three distribution discs decreasing sequentially from top to bottom, and a spacing between the three distribution discs; the axis of the pipe connector coincides with the axis of the distribution discs.

[0005] A frustum is provided on the upper side of a single fabric tray. The frustum is coaxial with the fabric tray, and the diameter of the cross-section of the frustum gradually increases from top to bottom. The three frustums are referred to as the first frustum, the second frustum, and the third frustum from top to bottom. The center of the upper side of the first frustum and the second frustum is provided with a through hole for material passage. The axis of the through hole coincides with the axis of the corresponding frustum.

[0006] Multiple fabric teeth are evenly distributed along the circumference on the upper side of a single fabric disc. An angle is set between the fabric teeth and the fabric disc, and a gap is set between two adjacent fabric teeth. The fabric teeth are located near the edge of the fabric disc.

[0007] At least two connecting rods are evenly distributed around the outer periphery of the fabric tray. The outer periphery of each connecting rod is connected to all three fabric trays. The upper end of the connecting rod is connected to the lower end of the pipe joint.

[0008] The inner diameter of the pipe joint is greater than the through hole diameter of the first frustum and less than the maximum diameter of the first frustum; the through hole diameter of the first frustum is greater than the through hole diameter of the second frustum and less than the maximum diameter of the second frustum; the through hole diameter of the second frustum is less than the maximum diameter of the third frustum.

[0009] Furthermore, the fabric teeth are triangular, with the tops of the fabric teeth extending outwards, and the included angle between the fabric teeth and the fabric disc is 40°~90°.

[0010] Furthermore, the diameter of the through hole is equal to the diameter of the top surface of the corresponding frustum.

[0011] Furthermore, the diameter of the top cross-section of the third frustum is 0.

[0012] Furthermore, there are four connecting rods.

[0013] Furthermore, the outer circumferential surface of the pipe fitting is provided with connecting threads.

[0014] The method of this utility model has the following beneficial effects: Since the feed head adopts a three-layer feeding disc to form an inverted feeding tower structure, a ring of feeding teeth is evenly distributed around the edge of the feeding disc, and gaps are left between the feeding teeth. A truncated cone is also set in the middle of the feeding disc. Except for the bottom truncated cone, the center of the two upper truncated cones is opened, forming a three-stage dispersion feeding and defoaming aeration structure. When the liquid medicine enters the feed head from the feed pipe, a portion of the medicine first falls onto the inclined surface of the first truncated cone at the top. After being accelerated, redirected, and evenly distributed by the inclined surface, the medicine is dispersed in a thin layer along the horizontal direction. When the medicine flows through the feeding teeth at the edge of the feeding disc, the air bubbles in the medicine are sheared and broken, and then the medicine forms droplets that fall from the periphery of the feeding disc into the aeration tank, thereby helping to eliminate some of the air bubbles in the medicine. Another portion of the medicine falls downward through the through holes of the first and second truncated cones to the two lower feeding discs respectively. The two lower feeding discs follow the same process as above, causing the medicine to be redirected, dispersed, sheared, and broken into droplets that fall from the periphery of the feeding disc into the aeration tank. Since the amount of medicine flowing through each feeding disc gradually decreases from top to bottom, the diameter of the feeding disc also gradually decreases in order to improve the feeding efficiency. Each time the liquid medicine circulates and aerates in the aeration tank, it undergoes a three-stage diversion and defoaming aeration process through the feed head distribution tower described in this invention, which greatly shortens the aeration time of the aeration tank, improves production efficiency, and reduces energy consumption and production costs.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] As attached Figure 1 and attached Figure 2 The feed head of the microcapsule suspension aeration tank shown includes a pipe connector 1 and a distribution tower 2. The pipe connector 1 is located above the distribution tower 2. The distribution tower 2 includes three distribution discs 21, which are arranged coaxially along the vertical axis. The maximum diameter of the three distribution discs 21 decreases sequentially from top to bottom, and there is a gap between the three distribution discs 21. The axis of the pipe connector 1 coincides with the axis of the distribution disc 21.

[0022] A frustum is provided on the upper side of a single fabric tray 2-1. The frustum is coaxial with the fabric tray 21, and the diameter of the cross-section of the frustum gradually increases from top to bottom. The three frustums are referred to as the first frustum 22, the second frustum 23, and the third frustum 24 from top to bottom. The center of the upper side of the first frustum 22 and the second frustum 23 are provided with through holes for material passage, and the axis of the through hole coincides with the axis of the corresponding frustum.

[0023] Multiple fabric teeth 25 are evenly distributed along the circumferential direction on the upper side of a single fabric disc 21. An angle A is provided between the fabric teeth 25 and the fabric disc 21. A gap is provided between two adjacent fabric teeth 25. The fabric teeth 25 are located near the edge of the fabric disc 21.

[0024] At least two connecting rods 26 are evenly distributed around the outer periphery of the fabric tray 21. The outer periphery of each connecting rod 26 is connected to all three fabric trays 21. The upper end of the connecting rod 26 is connected to the lower end of the pipe joint 1.

[0025] The inner diameter of the pipe joint 1 is greater than the through hole diameter of the first frustum 22 and less than the maximum diameter of the first frustum 22; the through hole diameter of the first frustum 22 is greater than the through hole diameter of the second frustum 23 and less than the maximum diameter of the second frustum 23; the through hole diameter of the second frustum 23 is less than the maximum diameter of the third frustum 24.

[0026] To improve the shearing and crushing effect on the liquid medicine, the fabric teeth 25 are triangular, with the top of the fabric teeth 25 extending outward, and the included angle A between the fabric teeth 25 and the fabric disc 21 is 40°~90°.

[0027] In order to improve the efficiency of liquid flow while reducing the deceleration and stagnation of the liquid, the diameter of the through hole is equal to the diameter of the top surface of the corresponding frustum.

[0028] To prevent the liquid medicine from slowing down and stagnating on the surface of the lowest layer of fabric disc, the top cross-sectional diameter of the third disc 24 is 0.

[0029] To ensure optimal mechanical properties of the feed head while also balancing the efficiency of liquid diversion and minimizing obstruction of the liquid, four connecting rods 26 are provided.

[0030] This feed head can be connected to the feed pipe by welding or other means. However, in order to facilitate the replacement of this feed head, improve the maintenance efficiency of the feed pipeline, and reduce the cost of use, the outer circumferential surface of the pipe joint 1 is provided with connecting threads so as to achieve a detachable connection with the end of the feed pipe.
