Abstract
Description
Technical Field
[0001] This utility model relates to the field of pesticide manufacturing equipment technology, and in particular to a vibrating screen for cooling finished pesticide granules. Background Technology
[0002] During the manufacturing process of granulated pesticides, the granules are relatively moist after granulation and need to be dried before subsequent packaging. For drying granulated pesticides, fluidized bed drying equipment is generally used. The pesticides are at a high temperature after drying, and direct packaging will affect the quality. In addition, for some pesticide varieties, the moisture on the surface of the finished granules does not evaporate quickly after flowing out of the fluidized bed, causing the granules to stick together and form lumpy granules, which affects the appearance of the product.
[0003] Existing technology CN210425771U discloses an online cooling vibrating screen for pesticide granules. This device adds a cooling unit to a traditional vibrating screen. Cooling air enters the cooling circulation chamber through the air inlet to cool the dried granules and is discharged from the exhaust port at the top. Compared with the prior art, the advantages of this invention are: by connecting a cooling fan motor to the air inlet of the vibrating screen, cold air enters the cooling circulation chamber to cool the dried granules. The cold air removes residual heat from the surface of the granules and removes moisture that has not evaporated in time, which not only increases the drying efficiency of the granules but also prevents the granules from sticking together, ensuring the quality and grade of the product.
[0004] However, in the above structure, particle accumulation or localized obstruction can hinder the penetration of cold air. Relying solely on vibration for dispersion is ineffective, thus affecting heat exchange efficiency. At the same time, uneven distribution of cold air flow, especially on the side furthest from the air inlet, results in poor heat dissipation. Utility Model Content
[0005] The purpose of this invention is to provide a vibrating screen for cooling finished pesticide granules, which solves the problems of granule accumulation or localized obstruction of cold air penetration, poor dispersion effect of vibration alone, and thus affecting heat exchange efficiency. At the same time, the uneven distribution of cold air flow and the poor heat dissipation effect on the side away from the air inlet are also problems.
[0006] To achieve the above objectives, this utility model provides a vibrating screen for cooling pesticide granules, comprising a cooling cylinder, an mounting ring, multiple air supply pipes, a loading assembly, a motor, a rotating shaft, two scraper blades, and multiple stirring blades. The cooling cylinder has a feed inlet at its top and a discharge outlet at its bottom. An mounting port is provided on the outer wall of the cooling cylinder. The mounting ring is mounted on the inner wall of the cooling cylinder. Multiple air supply pipes are respectively connected to the mounting ring and located above it. The loading assembly is disposed inside the cooling cylinder and connected to the feed inlet. The motor is mounted above the cooling cylinder, and its output end penetrates the cooling cylinder. The rotating shaft is mounted on the output end of the motor. The two scraper blades are respectively fixedly connected to the rotating shaft and located opposite each other on both sides of the rotating shaft. Multiple stirring blades are respectively mounted on the outer wall of the rotating shaft.
[0007] The loading assembly includes a mounting frame, a connecting cover, a filter screen, and a vibration component. The mounting frame is fixedly connected to the cooling cylinder and has multiple air holes. One end of the connecting cover is fixedly connected to the mounting frame, and the other end of the connecting cover is fixedly connected to the filter screen. The vibration component is disposed on the outer wall of the cooling cylinder and connected to the filter screen.
[0008] The vibration component includes a mounting plate, a vibration motor, and a connecting rod. The mounting plate is fixedly connected to the cooling cylinder and is located on the outer side wall of the cooling cylinder. The vibration motor is mounted above the mounting plate. One end of the connecting rod is connected to the vibration motor, and the other end passes through the mounting port and is connected to the filter screen.
[0009] The pesticide granule finished product cooling vibrating screen also includes an air exchange mechanism, which is located above the cooling cylinder.
[0010] The ventilation mechanism includes a traction fan and an exhaust pipe. The traction fan is installed above the cooling cylinder, and the output end of the traction fan extends into the cooling cylinder. The exhaust pipe is installed at the output end of the traction fan.
[0011] This utility model discloses a vibrating screen for cooling finished pesticide granules. In use, an external cold air duct is connected to the mounting ring. Cold air is discharged into the cooling cylinder through the mounting ring and the air supply duct. Granules are added to the loading assembly through the feed inlet. The motor operates, the rotating shaft rotates, the stirring blades agitate the granules, and the scraper agitates the outer granules, facilitating mixing with the inner granules, reducing temperature gradients, ensuring uniform cooling, and preventing a small amount of water-containing granules from adhering to the inner wall, thus avoiding raw material waste. This invention solves the problems of granule accumulation or localized obstruction of cold air penetration, resulting in poor dispersion through vibration alone and thus affecting heat exchange efficiency. It also addresses the issues of uneven cold air distribution and poor heat dissipation on the side furthest from the air inlet. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION
[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention. Example
[0019] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of the first embodiment of the present invention.Figure 2 This is a schematic diagram of the internal structure of the cooling cylinder according to the first embodiment of this utility model. Figure 3 This is a schematic diagram of the internal structure of the mounting frame according to the first embodiment of this utility model.
[0020] This utility model provides a vibrating screen for cooling pesticide granules, including a cooling cylinder 101, a mounting ring 102, multiple air supply pipes 103, a loading assembly, a motor 104, a rotating shaft 105, two scraper plates 106, and multiple stirring blades 107. The loading assembly includes a mounting frame 108, a connecting cover 109, a filter screen 110, and a vibrating component. The vibrating component includes a mounting plate 111, a vibrating motor 112, and a connecting rod 113. The above structure solves the problems of granule accumulation or localized obstruction of cold air penetration, poor dispersion effect of vibration alone, and thus affecting heat exchange efficiency. At the same time, the cold air flow distribution is uneven, and the heat dissipation effect is poor on the side away from the air inlet.
[0021] In a specific embodiment, the cooling cylinder 101 has a feed inlet 114 at its top and a discharge outlet 115 at its bottom. An installation port is provided on the outer wall of the cooling cylinder 101. An installation ring 102 is installed on the inner wall of the cooling cylinder 101. Multiple air supply pipes 103 are connected to and located above the installation ring 102. A loading assembly is disposed inside the cooling cylinder 101 and connected to the feed inlet 114. A motor 104 is installed above the cooling cylinder 101, with its output end penetrating the cooling cylinder 101. A rotating shaft 105 is installed at the output end of the motor 104. Two scraper plates 106 are fixedly connected to the rotating shaft 105 and positioned opposite each other on either side of the rotating shaft 105. Multiple agitators... The stirring blades 107 are respectively installed on the outer wall of the rotating shaft 105, connecting the external cold air pipe to the mounting ring 102. The cold air is discharged into the cooling cylinder 101 through the mounting ring 102 and the air supply pipe 103. The particles are added into the loading assembly through the feed port 114. The motor 104 operates, the rotating shaft 105 rotates, the stirring blades 107 tumble the particles, and the scraper 106 tumbles the outer particles, which helps to mix with the inner particles, reduces the temperature gradient, and ensures uniform cooling. At the same time, it prevents a small number of water-containing particles from adhering to the inner wall, causing raw material waste. It solves the problem that particle accumulation or local backflow can hinder the penetration of cold air, and the dispersion effect of vibration alone is poor, which affects the heat exchange efficiency. At the same time, the uneven distribution of cold air flow and the poor heat dissipation effect on the side away from the air inlet are also problems.
[0022] The mounting frame 108 is fixedly connected to the cooling cylinder 101, and the mounting frame 108 is provided with multiple air holes. One end of the connecting cover 109 is fixedly connected to the mounting frame 108, and the other end of the connecting cover 109 is fixedly connected to the filter screen 110. The vibration component is disposed on the outer wall of the cooling cylinder 101 and connected to the filter screen 110. The connecting cover 109 is made of a relatively soft material, so that vibration will not affect the connection effect with the mounting frame 108 and the filter screen 110. During cooling, cold air is discharged through the air supply pipe 103. The cold air can exchange heat with the internal particles through the air holes on the mounting frame 108. After cooling, the vibration component operates, and under the action of the connecting cover 109, it drives the filter screen 110 to vibrate, thereby screening the particles.
[0023] The mounting plate 111 is fixedly connected to the cooling cylinder 101 and located on the outer wall of the cooling cylinder 101. The vibration motor 112 is mounted above the mounting plate 111. One end of the connecting rod 113 is connected to the vibration motor 112, and the other end passes through the mounting port and is connected to the filter screen 110. The mounting plate 111 is used to support the vibration motor 112. When the vibration motor 112 operates, the connecting rod 113 transmits vibration to the filter screen 110. The filter screen 110 vibrates to screen the particles. Qualified particles can pass through the filter screen 110. At the same time, the vibration can also prevent larger particles from clogging the filter screen 110 and affecting the discharge of qualified particles.
[0024] In using the pesticide granule cooling vibrating screen of this invention, an external cold air duct is connected to the mounting ring 102. Cold air is discharged into the cooling cylinder 101 through the mounting ring 102 and the air supply duct 103. Granules are added to the loading assembly through the feed inlet 114. The motor 104 operates, the rotating shaft 105 rotates, the stirring blades 107 agitate the granules, and the scraper 106 agitates the outer granules, which helps to mix them with the inner granules, reduces the temperature gradient, ensures uniform cooling, and prevents small amounts of granules from being mixed together. After the water-containing particles adhere to the inner wall and are cooled, the vibration motor 112 operates, and the connecting rod 113 transmits the vibration to the filter screen 110. The filter screen 110 vibrates to screen the particles. Qualified particles can pass through the filter screen 110. At the same time, the vibration can also prevent larger particles from clogging the filter screen 110 and affecting the discharge of qualified particles. This solves the problem that particle accumulation or localized backflow can hinder the penetration of cold air. The vibration dispersion effect is poor, which affects the heat exchange efficiency. At the same time, the cold air flow distribution is uneven, and the heat dissipation effect is poor on the side away from the air inlet. Example

[0026] Based on the first embodiment, the pesticide granule finished product cooling vibrating screen of this utility model also includes a ventilation mechanism, which includes a traction fan 201 and an exhaust pipe 202.
[0027] In a specific implementation, the ventilation mechanism is located above the cooling cylinder 101. The ventilation mechanism is used for active ventilation to increase airflow and promote heat exchange.
[0028] The traction fan 201 is installed above the cooling cylinder 101, and the output end of the traction fan 201 extends into the cooling cylinder 101. The exhaust pipe 202 is installed at the output end of the traction fan 201. When dissipating heat, the traction fan 201 operates to extract the hot air from the cooling cylinder 101 and discharge it to the outside of the cooling cylinder 101 through the exhaust pipe 202, so as to prevent hot air from accumulating in the cooling cylinder 101.
