Description

Technical Field

[0001] This invention relates to a sedimentation apparatus, specifically to a glue-making dehydration and sedimentation apparatus. Background Technology

[0002] Urea-formaldehyde resin adhesive is one of the most commonly used adhesives. Its main components are urea and formaldehyde. Due to its low cost, simple operation and excellent performance, it is widely used in the production of wood-based panels.

[0003] When producing the required urea-formaldehyde resin adhesive, a chemical reaction needs to be carried out in a reaction vessel. The tail gas generated during the reaction is drawn into a condenser tower by a vacuum pump, and the condensed water vapor is collected in a sedimentation tank.

[0004] However, the tail gas from the reactor directly enters the condenser tower. The glue aerosol contained in the tail gas gradually adheres to the small tubes inside the condenser tower. After 2-3 months of use, the small tubes of the condenser tower will become blocked, causing the condenser to fail and making normal production impossible. Summary of the Invention

[0005] The main objective of this invention is to provide a glue dehydration and sedimentation device. Before the exhaust gas enters the condenser tower, a sedimentation and filtration device is constructed. By reducing the local wind speed, most of the glue aerosol particles are intercepted through this sedimentation box, thereby solving the problem of blockage in the small tubes of the condenser tower.

[0006] To achieve the above objectives, the present invention provides a glue-making, dehydration, and sedimentation apparatus, comprising: Storage rack; Multiple sedimentation units are connected in series and placed on a shelf. Each sedimentation unit includes two side plates, a bottom plate, and an inner plate of predetermined thickness. The two side plates are detachably and sealed to the inner plate and are located on both sides of the inner plate. The bottom plate is located at the bottom of the inner plate and is sealed to the inner plate. The two ends of the bottom plate along its length are fastened to the two side plates respectively. The inner plate is provided with an S-shaped channel for exhaust gas flow.

[0007] Preferably, the inner plate has multiple spaced grooves on both sides and the bottom side, wherein the groove on one side of the inner plate is connected to the groove on the other side of the inner plate through the groove on the bottom side, thereby forming an S-shaped channel.

[0008] More preferably, the side plates facing the inner plate are coated with an adsorbent material for adsorbing glue aerosols in the water vapor.

[0009] Preferably, the side panel is detachably connected to the inner panel via a connector.

[0010] In a further preferred embodiment, the inner plate has symmetrically arranged elliptical first blind holes on both sides, and elliptical through holes on the side plate. The first blind holes and through holes are symmetrically arranged, and the connector can pass through the through hole, be inserted into the first blind hole, and then be fixed by the fixing rod.

[0011] More preferably, the connector includes a plug rod, an elliptical frustum-shaped rubber body, and a parallelogram-shaped elastic member. One side of the middle portion of the elastic member is fixedly connected to the plug rod, and the other side of the elastic member is slidably connected to the plug rod. One end of the plug rod is fixedly connected to the rubber body, and the other end of the plug rod is inserted into the blind hole. The rubber body can be inserted into the through hole of the side plate.

[0012] More preferably, the bottom of the built-in plate is provided with a cylindrical second blind hole, which intersects with the first blind hole. After the connector is inserted into the first blind hole, by rotating it, the two acute-angled ends of the elastic element can be inserted into the second blind hole.

[0013] More preferably, the bottom of the first blind hole is provided with a third blind hole, and the other end of the plug can be inserted into the third blind hole.

[0014] More preferably, the inner plate has a fourth blind hole on both sides, which intersects with the second blind hole, and the fixing rod can be inserted into the acute end of the elastic element.

[0015] The beneficial effects of this invention are as follows: The sedimentation device of this invention is composed of multiple sedimentation units connected in series. This allows for easy removal and cleaning of any blocked sedimentation unit while the others remain operational, thus ensuring the overall use of the device. Furthermore, this application designs the channels within the sedimentation units as S-shaped channels, which reduces local wind speed and promotes natural sedimentation of large particles.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figure 1 As shown, the present invention provides a glue-making dehydration and sedimentation device, including a placement rack 100 and a plurality of sedimentation units 200 connected in series, which are placed on the placement rack 100. The placement rack 100 includes two side plates 110 and a plurality of horizontal plates 120. The two side plates 110 are fixedly disposed on both sides of the horizontal plates 120, and the sedimentation units 200 are arranged sequentially on the horizontal plates 120.

[0021] In this embodiment, as Figure 2 and Figure 3As shown, the sedimentation unit 200 includes two side plates 240, a bottom plate 230, and an inner plate 250 of predetermined thickness. The two side plates 240 are detachably and sealed to the inner plate 250, and are located on opposite sides of the inner plate 250. The bottom plate 230 is located at the bottom of the inner plate 250 and is sealed to it. Both ends of the bottom plate 230 are fastened to the two side plates 240 along its length, preferably using bolts. The inner plate 250 has an S-shaped channel for exhaust gas flow, with the inlet 210 and outlet 220 of the S-shaped channel located at the top of the inner plate 250. Additionally, the side plates 240 facing the inner plate 250 are coated with an adsorbent material for adsorbing adhesive aerosols in water vapor. The exhaust gas enters the sedimentation unit 200 through the air inlet 210. During the flow of the exhaust gas through the S-shaped channel, the S-shaped channel slows down the flow speed of the exhaust gas, so large particles in the exhaust gas will automatically settle on the bottom plate 230 (therefore, the inner plate 250 needs to have a certain thickness so that the bottom plate 230 can receive these large particles and prevent them from clogging the bottom plate 230). At the same time, the side plate 240 is coated with adsorption material, so that the glue aerosol in the exhaust gas is adsorbed on the adsorption material during the flow of the exhaust gas, thereby achieving the purpose of purifying the exhaust gas.

[0022] In addition, in this embodiment, since multiple precipitation units 200 are used in series, when a precipitation unit 200 needs to be repaired, only the precipitation unit 200 that needs to be repaired needs to be removed, and the other precipitation units 200 can still be used without affecting the overall use of the precipitation device.

[0023] Specifically, in this embodiment, such as Figure 6 and Figure 7 As shown, the built-in plate 250 has multiple spaced grooves on both sides and the bottom. The groove on one side of the built-in plate 250 connects to the groove on the other side of the built-in plate 250 via a groove on the bottom, thus forming an S-shaped channel. This S-shaped channel surrounds both sides and the bottom of the built-in plate 250. This design separates the adhesive aerosol adsorbed by the side plate 240 from the large-particle sedimentation impurities, making cleaning easier. It also prevents the two from accumulating and clogging the S-shaped channel, extending the service life of the sedimentation unit 200.

[0024] In this embodiment, due to the operating environment of the sedimentation device (for producing adhesive), if the side plate 240 and the inner plate 250 are connected by bolts, the bolts may become covered with adhesive over time, making it difficult to remove the bolts. Therefore, in this embodiment, the side plate 240 is connected to the inner plate 250 by the connector 260 in a detachable manner.

[0025] Specifically, in this embodiment, such as Figures 2 to 4 As shown, the built-in plate 250 has symmetrically arranged elliptical first blind holes 251 on both sides, and the side plate 240 has elliptical through holes. The first blind holes 251 and the through holes are symmetrically arranged. The connector 260 can pass through the through hole and be inserted into the first blind hole 251 and then fixed by the fixing rod 270.

[0026] In this embodiment, as Figure 5 As shown, the connector 260 includes a rod 261, an elliptical frustum-shaped rubber body 263, and a parallelogram-shaped elastic member 262. One side of the middle part of the elastic member 262 is fixedly connected to the rod 261, and the other side of the elastic member 262 is slidably connected to the rod 261. One end of the rod 261 is fixedly connected to the rubber body 263, and the other end of the rod 261 is inserted into the blind hole. The rubber body 263 can be inserted into the through hole of the side plate 240.

[0027] like Figure 4 As shown, a cylindrical second blind hole 252 is provided at the bottom of the built-in plate 250. The second blind hole 252 intersects with the first blind hole 251. After the connector 260 is inserted into the first blind hole 251, by rotation, the two acute-angled ends of the elastic member 262 can be engaged in the second blind hole 252. In addition, a third blind hole 253 is provided at the bottom of the first blind hole 251, and the other end of the insertion rod 261 can be inserted into the third blind hole 253. A fourth blind hole 254 is provided on both sides of the built-in plate 250. The fourth blind hole 254 intersects with the second blind hole 252, and the fixing rod 270 can be inserted into the acute-angled end of the elastic member 262.

[0028] In this embodiment, the specific method of using connector 260 is as follows: First, the connector 260 is inserted into the first blind hole 251. During insertion, the acute angle end of the elastic element 262 faces the major axis of the elliptical first blind hole 251. After the insertion rod 261 of the connector 260 is inserted into the bottom of the third blind hole 253, the connector 260 is rotated so that the acute angle end of the elastic element 262 can be engaged in the third blind hole 253. At the same time, the rubber body 263 of the connector 260 can be engaged in the elliptical through hole of the side plate 240. Finally, the fixing rod 270 is inserted into the fourth blind hole 254. During insertion, the fixing rod 270 can pass through the acute angle end of the elastic element 262, thereby fixing the connector 260 and finally fixing the side plate 240 and the inner plate 250 together. In this embodiment, the fixing rod 270 continuously pulls the acute angle end of the elastic element 262 while it is inserted into the blind hole, which makes the rubber body 263 more tightly connected to the through hole of the side plate 240.

[0029] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
