Abstract
Description
Technical Field
[0001] This utility model relates to the field of activation treatment technology, specifically to an activation device for heavy calcium carbonate. Background Technology
[0002] Heavy calcium carbonate, a commonly used inorganic powder filler, exhibits poor compatibility with its matrix (organic polymer) due to differences in surface or interfacial properties. Consequently, it is difficult to disperse uniformly within the matrix, and direct or excessive filling often leads to a decline in certain mechanical properties and embrittlement. Therefore, it is necessary to activate the surface of calcium carbonate to improve its physicochemical properties, enhance its compatibility with the matrix (organic polymer or resin), and improve its dispersibility within the organic matrix, thereby increasing the material's mechanical strength and overall performance.
[0003] In the prior art, utility model patent with announcement number CN218654655U provides an activation treatment device for the production of heavy calcium carbonate, belonging to the field of activation treatment technology. It includes a base frame and four support columns installed on its top. A grinding box is fixedly connected to the top of the support columns. The top of the grinding box is provided with a feed port for feeding heavy calcium carbonate. Two first grinding motors for grinding are connected to one side of the grinding box. A first rotating shaft is connected through the grinding box to one side of the first grinding motor. A first grinding roller for one-time grinding of heavy calcium carbonate is connected to the outer side of the first rotating shaft. A rotating block is connected to the other side of the first rotating shaft. Moving slide rails for movement are connected to the inner walls of both sides of the grinding box. A screen for filtering heavy calcium carbonate is connected to the inner groove of the moving slide rail.
[0004] The current activation treatment device for the production of heavy calcium carbonate requires manual removal of non-conforming heavy calcium carbonate, which involves a large amount of manual work. It also requires manual feeding above the grinding box, making the work difficult. Therefore, we propose a heavy calcium carbonate activation device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a heavy calcium carbonate activation device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A heavy calcium carbonate activation device includes a grinding box containing two sets of grinding equipment mounted on a fixed base. The bottom openings of the grinding equipment connect to a mixing tank. A filtration mechanism is provided on the grinding box for filtering a portion of the heavy calcium carbonate. The filtration mechanism includes a filter seat positioned between the two sets of grinding equipment on the grinding box. A pusher plate for pushing the heavy calcium carbonate onto the filter seat is slidably mounted on the filter seat. One end of the pusher plate is connected to a telescopic push rod for moving the pusher plate. A baffle for moving and blocking one opening of the filter seat is provided at the opening away from the telescopic push rod. The baffle is slidably mounted on a limiting rod, which has a spring for pushing the baffle to contact the outer wall of the grinding box. A material conveying mechanism is located below the end of the filter seat away from the telescopic push rod.
[0008] Preferably, the feeding mechanism is used to receive the heavy calcium carbonate discharged from the opening at one end of the filter seat, and to transport the heavy calcium carbonate to the feed inlet at the top of the grinding box.
[0009] Preferably, the material conveying mechanism includes a receiving hopper located below one end of the filter seat, and a conveyor for conveying materials is connected to the bottom outlet of the receiving hopper.
[0010] Preferably, one end of the filter seat is fixedly inserted through the grinding box, and the push plate moves within the groove of the filter seat.
[0011] Preferably, the filter seat has a U-shaped structure and a mesh structure at the bottom.
[0012] Preferably, the telescopic push rod is mounted on the grinding box, and the baffle is used to block the opening where the filter seat passes through the grinding box.
[0013] Preferably, the telescopic push rod has a telescopic length greater than the filter seat length.
[0014] Preferably, the limiting rod is fixed to the outer wall of the grinding box, and one end of the spring is connected to the baffle, and the other end is connected to the limiting rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. Drive the telescopic push rod to move the push plate. The push plate moves the heavy calcium carbonate on the filter seat to one side of the baffle. The baffle moves on the limit rod to compress the spring. After the baffle separates from the grinding box and the filter seat, the baffle pushes the heavy calcium carbonate on the filter seat out of the filter seat. After collection, it is poured into the grinding box and ground again by a set of grinding equipment at the top. This avoids the need for manual removal of unsuitable heavy calcium carbonate and reduces the amount of manual labor.
[0019] 2. Pour the heavy calcium carbonate into the receiving hopper. The heavy calcium carbonate enters the conveyor through the receiving hopper. The conveyor directly feeds the material into the top feed port of the grinding box. The push plate pushes the heavy calcium carbonate on the filter seat out into the receiving hopper. The material is fed by the conveyor, avoiding the need for manual feeding above the grinding box and reducing the difficulty of the work. Attached Figure Description

[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 Figure 1-3A heavy calcium carbonate activation device includes a grinding box 1, which contains two sets of grinding devices 2 with different grinding specifications. The set of grinding devices 2 near the bottom of the grinding box 1 has a higher grinding specification. The grinding devices 2 are mounted on a fixed base 3, and the bottom opening of the grinding devices 2 connects to a mixing tank 4. The mixing tank 4 is mounted on the fixed base 3. Heavy calcium carbonate is poured into the feed inlet at the top of the grinding box 1, where it is ground by one set of grinding devices 2. The calcium carbonate then falls onto a filter seat 51 and falls downwards through the filter seat 51, where it undergoes a second grinding by the other set of grinding devices 2. The ground heavy calcium carbonate then falls into the mixing tank 4, where it is ground and heated. The activated heavy calcium carbonate is then discharged through the discharge outlet of the mixing tank 4. This is the prior art.
[0026] The grinding chamber 1 is equipped with a filter mechanism 5, which is used to filter some of the heavy calcium carbonate. The filter mechanism 5 includes a filter seat 51 located on the grinding chamber 1 between the two sets of grinding equipment 2. A push plate 52 for pushing the heavy calcium carbonate on the filter seat 51 is slidably mounted on the filter seat 51. One end of the push plate 52 is connected to a telescopic push rod 53 for pushing the push plate 52 to move. A baffle 54 for moving and blocking one side opening of the filter seat 51 is provided at the opening on the side away from the telescopic push rod 53. The baffle 54 is slidably mounted on a limiting rod 55, and the limiting rod 55 is provided with a baffle 54 for pushing the baffle 54. The spring 56 moves to contact the outer wall of the grinding box 1. The filter seat 51 has a U-shaped structure and a mesh mechanism at the bottom. One end of the filter seat 51 is fixed through the grinding box 1. The push plate 52 moves in the groove of the filter seat 51. The telescopic push rod 53 is set on the grinding box 1. The telescopic push rod 53 has a telescopic length greater than the length of the filter seat 51. The baffle 54 is used to move and block the opening of the filter seat 51 through the grinding box 1. The limiting rod 55 is fixed on the outer wall of the grinding box 1. The length of the limiting rod 55 is greater than the length of the filter seat 51 outside the grinding box 1. One end of the spring 56 is connected to the baffle 54, and the other end is connected to the limiting rod 55.
[0027] Drive the telescopic push rod 53 to push the push plate 52 to move. The push plate 52 moves and pushes the heavy calcium carbonate on the filter seat 51 to move towards the baffle 54. The baffle 54 moves on the limit rod 55 to compress the spring 56. After the baffle 54 separates from the grinding box 1 and the filter seat 51, the baffle 54 pushes the heavy calcium carbonate on the filter seat 51 out of the filter seat 51. After collection, it is poured into the grinding box 1 and ground again by a set of grinding equipment 2 at the top. This avoids the need for manual removal of unsuitable heavy calcium carbonate and reduces the amount of manual labor.
[0028] A conveying mechanism 6 is provided below the end of the filter seat 51 away from the telescopic push rod 53. The conveying mechanism 6 is used to receive the heavy calcium carbonate discharged from the opening at one end of the filter seat 51 and to transport the heavy calcium carbonate to the top feed inlet of the grinding box 1. The conveying mechanism 6 includes a receiving hopper 61 located below one end of the filter seat 51. A conveyor 62 for conveying materials is connected to the bottom outlet of the receiving hopper 61. The receiving hopper 61 is fixed on the outer wall of the grinding box 1. The discharge end of the conveyor 62 is at the top feed inlet of the grinding box 1. The feed end of the conveyor 62 is connected to the bottom outlet of the feeding hopper 61. The conveyor 62 is fixed on the outer wall of the grinding box 1. The conveyor 62 can be a screw conveyor.
[0029] Heavy calcium carbonate is poured into the receiving hopper 61 and then enters the conveyor 62. The conveyor 62 directly feeds the material into the top feed port of the grinding box 1. The pusher plate 52 pushes the heavy calcium carbonate on the filter seat 51 into the receiving hopper 61. The material is fed by the conveyor 62, which avoids the need for manual feeding above the grinding box 1 and reduces the difficulty of the work.
[0030] Working principle: This utility model drives the telescopic push rod 53 to push the push plate 52 to move. The push plate 52 moves and pushes the heavy calcium carbonate on the filter seat 51 to the side of the baffle 54. The baffle 54 moves on the limiting rod 55 to compress the spring 56. After the baffle 54 separates from the grinding box 1 and the filter seat 51, the baffle 54 pushes the heavy calcium carbonate on the filter seat 51 out of the filter seat 51. After collection, it is poured into the grinding box 1 and ground again by a set of grinding equipment 2 at the top. This avoids the need for manual removal of unsuitable heavy calcium carbonate, reducing the amount of manual labor. The heavy calcium carbonate is poured into the receiving hopper 61 and enters the conveyor 62 through the receiving hopper 61. The conveyor 62 directly feeds the material into the top feed port of the grinding box 1. The push plate 52 pushes the heavy calcium carbonate on the filter seat 51 out into the receiving hopper 61 and feeds it through the conveyor 62. This avoids the need for manual feeding above the grinding box 1 and reduces the difficulty of the work.
