Description

Technical Field

[0001] This utility model relates to the technical field of adhesive preparation equipment, specifically a fully enclosed environmentally friendly adhesive preparation system. Background Technology

[0002] In the production process of particleboard, glue is used to mix wood powder made from wood chips or other wood scraps evenly. This process is called glue mixing, and the glue used is usually called adhesive. The type and quality of the adhesive used will seriously affect the quality and performance of the finished particleboard. For example, if the glue has a low content of formaldehyde or benzene and other chemicals, the resulting particleboard will be environmentally friendly. Furthermore, if the glue has fire-retardant properties, the resulting particleboard will also be fire-resistant. Therefore, ensuring the quality of glue preparation is a crucial step in the particleboard manufacturing process.

[0003] Wood processing plants typically use glue-making systems to prepare glue. However, in traditional glue preparation processes, harmful chemicals in the glue can diffuse into the air, seriously endangering the health of the workers. Furthermore, fully enclosed glue-making systems are inconvenient to operate, observe, and test, making it impossible to control and guarantee the quality of the glue in real time.

[0004] Therefore, based on the above shortcomings, a fully enclosed, environmentally friendly adhesive manufacturing system is needed. Utility Model Content

[0005] The purpose of this invention is to provide a fully enclosed, environmentally friendly adhesive-making system to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fully enclosed, environmentally friendly adhesive-making system includes a preparation tank for adding and mixing reactants therein. The preparation tank has a support frame at its bottom, several inlet pipes at its top, and an outlet pipe at its bottom. The system is characterized by a stirring mechanism within the preparation tank, comprising a stirring motor mounted at the top of the tank and a stirring rod connected to the motor's main shaft. The stirring rod is rotatably connected to the top of the tank via a supporting assembly. Several sets of agitators are located at the end of the stirring rod furthest from the stirring motor. Several inlet pipes are connected to several storage tanks for adding different reactants into the preparation tank. An observation panel is formed at the front of the preparation tank for workers to observe the internal conditions.

[0008] Preferably, the observation body is made of transparent glass material and is integrally connected to the preparation tank.

[0009] Preferably, a searchlight is provided at the top of the preparation tank, and the searchlight is used to illuminate the inner cavity of the preparation tank.

[0010] Preferably, the storage tank body has four tanks, namely a first tank, a second tank, a third tank and a fourth tank, and the first tank, the second tank, the third tank and the fourth tank are respectively connected to the corresponding feed pipe.

[0011] Preferably, the stirrer includes a fixed arm fixedly disposed at the end of the stirring rod away from the stirring motor, a suspension arm rotatably connected to the free end of the fixed arm, a centrifugal ball disposed at the tail end of the suspension arm, and a plurality of evenly distributed extended stirring arms formed on the surface of the suspension arm, the centrifugal ball being used to generate centrifugal force to stretch the suspension arm when the stirrer rotates.

[0012] Preferably, the stirrer has three sets, namely a first stirring component, a second stirring component and a third stirring component, which are respectively arranged from top to bottom at the end of the stirring rod away from the stirring motor.

[0013] Preferably, the extended stirring arm of the third stirring assembly is connected to the stirring rod via an elastic connecting strap.

[0015] Preferably, the detection device includes a transparent detection cup, a material receiving pipe connecting the detection cup to the bottom of the preparation tank, and a return pipe connecting the detection cup back to the preparation tank, wherein a return pump is provided in the return pipe back to the preparation tank.

[0016] Preferably, the top of the test cup is open, and the top opening is sealed by an elastic connecting cover, the end of which, away from the top opening, is sealed and clamped to a stirring rod with one end extending into the test cup.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The preparation tank of this utility model is a fully sealed tank. The top of the preparation tank is connected to each storage tank through the feed pipe to realize the closed feeding of all pipelines. The bottom of the preparation tank can also be connected to the discharge tank through the outlet pipe.

Detailed Implementation

[0028] 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.

[0029] In particleboard manufacturing plants, it is usually necessary to prepare glue as needed to achieve the mixing process of using the glue to evenly mix wood powder made from wood chips or other wood scraps. Preparing glue requires a complete glue preparation system.

[0030] like Figure 1 and Figure 4 As shown, this utility model is a fully enclosed, environmentally friendly adhesive preparation system. Similar to commonly used adhesive preparation systems, this system specifically includes a preparation tank 2 for adding and mixing reactants. A support frame 1 is provided at the bottom of the preparation tank 2, and several feed pipes 21 are provided at the top of the preparation tank 2. These feed pipes 21 are respectively connected to several storage tanks 3 for adding different reactants to the preparation tank 2. For example, the preparation of commonly used polyvinyl alcohol (PVA) adhesives currently on the market uses four reactants, including water: a mixture of ethylene glycol and water, a mixture of polyacrylamide and water, and a mixture of heavy calcium carbonate and water. Therefore, further in this embodiment, the storage tank 3 has four components: a first tank 31, a second tank 32, a third tank 33, and a fourth tank 34. The first tank 31, the second tank 32, the third tank 33, and the fourth tank 34 are each connected to a corresponding feed pipe 21. In use, the first tank 31, the second tank 32, the third tank 33, and the fourth tank 34 are first quantitatively stored in proportions of a mixture of ethylene glycol and water, a mixture of polyacrylamide and water, a mixture of heavy calcium carbonate and water, and water, etc., and then sequentially injected and stirred according to the polyvinyl alcohol (PVA) adhesive preparation process. Of course, the adhesive preparation system can also be used to prepare other wood shaving adhesives, such as the currently popular and very environmentally friendly lignin-based formaldehyde-free adhesives.

[0031] Prepared adhesives often contain certain harmful substances; therefore, further... Figure 1 As shown, the bottom of the preparation tank 2 is provided with an outlet pipe 22, which can be closedly connected to the feeding tank for feeding, and then transported to the next process stage for use.

[0032] In the preparation process of the adhesive, to accelerate the reaction or fusion of the reactants, the preparation tank 2 is also equipped with a stirring mechanism 4, specifically, as follows: Figure 1and Figure 2 As shown, the stirring mechanism 4 includes a stirring motor 41 mounted on the top of the preparation tank 2 and a stirring rod 42 connected to the main shaft of the stirring motor 41. The rotational speed of the stirring rod 42 can be controlled by controlling the rotational speed of the stirring motor 41. The stirring rod 42 is rotatably connected to the top of the preparation tank 2 via a supporting body 43. The rotatable connection between the supporting body 43 and the top of the preparation tank 2 is a sealed connection to prevent harmful substances from flowing out of the preparation tank 2. Preferably, four sealing rings are added between the supporting body 43 and the stirring rod 42. Furthermore, a plurality of agitators 44 are provided at the end of the stirring rod 42 away from the stirring motor 41. The agitators 44 are integrally mounted with the stirring rod 42 and rotate together. The agitators 44 have a wide stirring range and high efficiency.

[0033] Further optimizations, such as Figure 1 and Figure 2 As shown, the specific structure of the stirrer 44 of this utility model is as follows: The stirrer 44 includes a fixed arm 4401 fixedly disposed at one end of the stirring rod 42 away from the stirring motor 41. The free end of the fixed arm 4401 is rotatably connected to a suspension arm 4402. Preferably, the rotatable connection adopts an undamped hinge connection, that is, the fixed arm 4401 will droop due to gravity. Furthermore, a centrifugal ball 4403 is provided at the tail end of the suspension arm 4402. When the stirrer 44 rotates at different speeds, the centrifugal ball 4403 will generate different centrifugal forces. The centrifugal force will stretch the suspension arm 4402 relative to the stirring rod 42. Moreover, the stretched suspension arm 4402 will swing up and down due to different rotation speeds, so that the suspension arm 4402 has an up-and-down stirring effect while rotating and stirring, realizing a comprehensive stirring effect on the reactants, making the reaction and fusion of the reactants more efficient and more uniform.

[0034] Furthermore, a plurality of evenly distributed extended stirring arms 4404 are formed on the surface of the suspension arm 4402. The function of these extended stirring arms 4404 is to increase the stirring range of the suspension arm 4402 on its surroundings. Specifically, for example... Figure 2 and Figure 3 As shown, the extended stirring arm 4404 extends from the surface of the suspension arm 4402 in a direction perpendicular to the axis of the suspension arm 4402. Preferably, there are three pairs of extended stirring arms 4404 that are symmetrical about the axis of the suspension arm 4402, so that the stirring range is wider.

[0035] Similar to the above-mentioned arrangement of three pairs of extended stirring arms 4404, the stirrer 44 also has three sets to increase the stirring range and improve the flow between the reactants, such as... Figure 1As shown, the stirrer 44 is divided into a first stirring component 441, a second stirring component 442, and a third stirring component 443. The first stirring component 441, the second stirring component 442, and the third stirring component 443 are arranged sequentially from top to bottom at the end of the stirring rod 42 furthest from the stirring motor 41. The third stirring component 443 is closest to the tail end of the stirring rod 42. Figure 1 As shown, since the suspension arm 4402 of the third stirring component 443 is also naturally suspended by gravity and only lifted by centrifugal force when there is rotational speed, the suspension arm 4402 of the third stirring component 443 cannot stir to the position directly below the stirring rod 42. Therefore, further optimization is needed, such as... Figure 3 As shown, the extended stirring arm 4404 of the third stirring assembly 443 is connected to the stirring rod 42 via an elastic connecting belt 4405. The elastic connecting belt 4405 has the power to pull the extended stirring arm 4404 toward the stirring rod 42, so that when the third stirring assembly 443 rotates at low speed, the suspension arm 4402 can stir the reactants remaining directly below the stirring rod 42, preventing some reactants from remaining directly below the stirring rod 42 for a long time, which would lead to insufficient reaction and fusion of the reactants.

[0036] Because the glue-making system of this invention adopts a fully enclosed structure, the glue-making process in the preparation tank 2 cannot be detected. A common solution is to install sensors in the preparation tank 2 for real-time monitoring. However, sensors are not as reliable as manual observation. Therefore, specifically, as... Figure 4 and Figure 6 As shown, an observation body 6 is formed at the front of the preparation tank 2 for workers to observe the interior of the preparation tank 2. It is easy to see that the observation body 6 is made of transparent glass and is integrally connected to the preparation tank 2. Through this observation body 6, the characteristics of the adhesive in the preparation tank 2 can be observed, mainly the color or viscosity of the adhesive, to determine the completion status of the adhesive preparation; correspondingly, as... Figure 1 , Figure 4 and Figure 6 As shown, a searchlight 5 is provided at the top of the preparation tank 2. The searchlight 5 shines into the inner cavity of the preparation tank 2, and the illuminated inner cavity of the preparation tank 2 is observed in conjunction with the observation body 6. Preferably, multiple searchlights 5 are arranged in a ring at the top of the preparation tank 2.

[0037] To further optimize the glue testing process and results of this glue preparation system, such as... Figure 4 , Figure 5 and Figure 6As shown, a detection device 7 is connected to the bottom of the preparation tank 2. The detection device 7 is used to extract a small amount of the adhesive being prepared in the preparation tank 2 for testing. This detection device 7 can extract a portion of the adhesive for testing while it is being prepared, in order to monitor the preparation effect in real time. Specifically, as shown... Figure 5 As shown, the detection device 7 includes a transparent detection cup 71, a material taking pipe 74 connecting the detection cup 71 to the bottom of the preparation tank 2, and a return pipe 75 connecting the detection cup 71 back to the preparation tank 2. A return pump 76 is installed in the return pipe 75 to the preparation tank 2. By opening the material taking pipe 74, the glue in the preparation tank 2 flows into the detection cup 71 under the influence of gravity and air pressure. After a sufficient amount is obtained, the material taking pipe 74 is closed. The glue in the detection cup 71 can be directly observed through the detection cup 71, or the glue can be taken out and taken to other equipment for testing or analysis. The operation is very simple, convenient and safe.

[0038] Further optimized, similar to traditional cups, such as Figure 5 As shown, the test cup 71 has an opening at the top, through which glue can be extracted. Furthermore, the top opening is sealed by an elastic connecting cover 73. Test rods or test paper can be placed into the test cup 71 through the elastic connecting cover 73. Preferably, a stirring rod 72 with one end extending into the test cup 71 is sealed and clamped at the end of the elastic connecting cover 73 away from the top opening. Due to the elasticity of the elastic connecting cover 73, the stirring rod 72 can be manually held to stir or dip into the glue in the test cup 71, so as to observe the viscosity of the glue and judge the quality of the prepared glue.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
