Description

Technical Field

[0001] This application belongs to the field of granulator technology, specifically a wet mixing granulator. Background Technology

[0002] A wet granulation machine is a piece of equipment used in the pharmaceutical and chemical industries. It is primarily used to mix powdered raw materials with binders under humid conditions and form granules. Its working principle involves mixing the raw materials and binder, then using mechanical force and a humid environment to form granules. These wet granules are then shaped into the desired shape and size using specific forming devices (such as molds or extrusion plates). This equipment is commonly used to prepare tablets, granules, and granule dosage forms, and is characterized by high efficiency and strong controllability, making it suitable for the granulation stage in various pharmaceutical processes.

[0003] The high-speed wet mixing granulator described in announcement number CN220657886U includes a machine body and a mixer mounted on the machine body. A sealing cover is provided at the upper end of the mixer, and a feed pipe is located above the sealing cover. A control valve is installed on the feed pipe. The granulator also includes a mounting box connected to the sealing cover, with the lower end of the feed pipe communicating with the mounting box. The mounting box is equipped with a metal removal component for removing metal objects during the feeding process. In this high-speed wet mixing granulator, as the material is conveyed on the mounting box, it slides across the upper surface of a guide plate. During this sliding process, any metal objects present inside the material are attracted to the guide plate by the magnetic force of the magnetic blocks, thus removing the metal objects. This prevents the loss of pressure rollers and ring dies due to metal objects being conveyed into the machine body, facilitating the normal operation of the high-speed wet mixing granulator.

[0004] However, in this device, the magnetic blocks attract metal materials to the guide plate but fail to separate and remove them in time. Subsequent materials will impact the magnetic blocks, causing some metal materials to be carried away from the surface of the magnetic blocks under the impact force and enter the machine body, which will damage the machine body. Furthermore, when the surface of the magnetic blocks is full of adsorption, the magnetic block's adsorption force will decrease, requiring the machine to be stopped for cleaning, thus reducing work efficiency. Utility Model Content

[0005] The purpose of this application is to address the problems in the aforementioned device where the magnetic block adsorbs metal materials onto the guide plate but fails to separate and remove them in time, causing subsequent materials to impact the plate, resulting in some metal materials being carried away from the surface of the magnetic block and entering the machine body, causing damage to the machine body. Furthermore, when the surface of the magnetic block is saturated with adsorption, the magnetic block's adsorption force decreases, requiring the machine to be stopped for cleaning, thus reducing work efficiency. The application provides a wet mixing granulation machine.

[0006] The technical solution adopted in this application is as follows: A wet mixing granulator includes a granulator body, with support legs installed at the four corners of the lower surface of the granulator body, a control panel provided on one side of the upper surface of the granulator body, a mixer provided on one side of the upper surface of the granulator body, a separation box installed on the upper surface of the mixer, a feed pipe connected to the upper end of the separation box, a guide plate provided inside the separation box, a conveyor belt corresponding to the guide plate installed inside the separation box, a plurality of electromagnetic rollers rotatably connected inside the conveyor belt, a baffle provided inside the separation box, a collection chamber corresponding to the conveyor belt provided between the baffle and the separation box, a connecting rod provided on the inner wall of the separation box, a scraper provided at one end of the connecting rod, the scraper abutting against one end surface of the conveyor belt, and a discharge port opened at the lower end of the separation box.

[0007] By adopting the above technical solutions and design, metal materials can be separated and collected for centralized processing, improving convenience and work efficiency, preventing metal materials from entering the interior of the pellet mill and causing damage, and extending the service life of the pellet mill body.

[0008] In a preferred embodiment, multiple sets of the guide plates and the conveyor belt are arranged inside the separation box, with each set arranged in a left-right cross pattern inside the separation box.

[0009] By adopting the above technical solution and through multiple settings, metals in materials can be removed through multiple screenings, reducing the probability of metals not being removed and improving work efficiency.

[0010] In a preferred embodiment, a control valve is installed on the outer surface of the feed pipe.

[0011] By adopting the above technical solution, the material entry speed can be controlled by the control valve, thus improving convenience.

[0012] In a preferred embodiment, an observation window is provided on one side of the separation box.

[0013] By adopting the above technical solution, the interior of the separation box can be observed, making it easier to detect and deal with problems in a timely manner, thus improving convenience.

[0014] In a preferred embodiment, metal collection boxes corresponding to the collection chamber are provided on both sides of the lower end of the separation box.

[0015] By adopting the above technical solution, the metal material falling into the collection chamber is collected through the inside of the metal collection box, which facilitates subsequent cleaning and improves convenience.

[0016] In a preferred embodiment, the support leg is provided with an electric push rod base inside, a telescopic rod is inserted into the lower end of the electric push rod base, a mounting plate is provided at the lower end of the telescopic rod, and a caster wheel is mounted at the lower end of the mounting plate.

[0017] By adopting the above technical solution, when the main body of the pellet mill needs to be moved, the telescopic rod is pushed by the electric push rod base, which causes the casters to move out of the support legs and make contact with the ground to support the main body of the pellet mill. Furthermore, the main body of the pellet mill is moved and transported by the casters. When it is moved to a suitable position, the casters are retracted into the support legs, so that the support legs support the main body of the pellet mill and improve the stability of the main body of the pellet mill.

[0018] In a preferred embodiment, limiting grooves are formed on both sides of the inner wall of the support leg, and limiting rods are provided inside the limiting grooves. Limiting sliders are provided on both sides of the mounting plate, and the limiting sliders are slidably connected to the outer surface of the limiting rods.

[0019] By adopting the above technical solution, the movement of the caster wheel is limited by the sliding of the limiting slider on the outer surface of the limiting slider, making its operation more stable and improving the stability of the device.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0021] In this application, during operation, the conveyor belt rotates on the upper surface of the material. Under the magnetic force of the electromagnetic roller, the metal material is adsorbed onto the surface of the conveyor belt. Furthermore, the metal material is moved to the baffle and intercepted, falling into the collection chamber, and then concentrated inside the metal collection box for collection. This improves convenience and work efficiency, prevents metal material from entering the interior of the granulator body and causing damage, and extends the service life of the granulator body.

A separation box 7 is installed on the upper surface of the mixer 3, and a feed pipe 5 is connected to the upper end of the separation box 7. A guide plate 12 is installed inside the separation box 7, and a conveyor belt 13 corresponding to the guide plate 12 is installed inside the separation box 7. Several electromagnetic rollers 15 are rotatably connected inside the conveyor belt 13. The separator is equipped with a baffle 11, and a collection chamber 14 corresponding to the conveyor belt 13 is provided between the baffle 11 and the separator 7. A connecting rod 18 is provided on the inner wall of the separator 7, and a scraper 17 is provided at one end of the connecting rod 18.

Through the above design, metal materials can be separated and collected for centralized processing, improving convenience and working efficiency, preventing metal materials from entering the interior of the granulator body 1 and causing damage, and extending the service life of the granulator body 1.

[0029] Reference Figure 2 The guide plate 12 and the conveyor belt 13 are arranged in multiple sets inside the separation box 7. Each set is arranged in a crisscross pattern inside the separation box 7. Through multiple sets, metal in the material can be screened and removed multiple times, reducing the probability of metal not being removed and improving work efficiency.

[0030] Reference Figure 1-2 A control valve 6 is installed on the outer surface of the feed pipe 5. The feed speed can be controlled by the control valve 6, which improves convenience.

[0031] Reference Figure 1 An observation window 4 is provided on one side of the separation box 7, which allows for observation of the interior of the separation box 7, facilitating timely detection and handling of problems and improving convenience.

[0032] Reference Figure 2-3 Metal collection boxes 8, corresponding to the collection chamber 14, are provided on both sides of the lower end of the separation box 7. Metal materials falling into the collection chamber 14 are collected through the interior of the metal collection box 8, which facilitates subsequent cleaning and improves convenience.

[0033] Reference Figure 1 and Figure 4 The support leg 10 is equipped with an electric push rod base 19. A telescopic rod 20 is inserted into the lower end of the electric push rod base 19. A mounting plate 21 is provided at the lower end of the telescopic rod 20. A caster wheel 2 is installed at the lower end of the mounting plate 21. When the pellet mill body 1 needs to be moved, the electric push rod base 19 pushes the telescopic rod 20, thereby causing the caster wheel 2 to move out of the support leg 10 and contact the ground to support the pellet mill body 1. Furthermore, the caster wheel 2 is used to move and transport the pellet mill body 1.

[0035] The implementation principle of a wet mixing granulator embodiment of this application is as follows:

[0036] During operation, the raw material falls into the separation box 7 through the feed pipe 5. Under the action of the guide plate 12, the raw material moves downward. Simultaneously, the electromagnetic roller 15 drives the conveyor belt 13 to rotate above the raw material. The magnetic force of the electromagnetic roller 15 attracts the metal material inside the raw material and makes it adhere to the surface of the conveyor belt 13. Furthermore, under the drive of the electromagnetic roller 15, the metal material is moved to the scraper 17. Further, under the interception of the scraper 17, the metal material falls into the collection chamber 14 and is then collected into the metal collection box 8 for easy cleaning, improving convenience and working efficiency, preventing metal material from entering the interior of the granulator body 1 and causing damage, and extending the service life of the granulator body 1.
