Description

Technical Field

[0001] This utility model belongs to the field of displacement cooking anti-deviation technology, and particularly relates to an anti-deviation device for DDS displacement cooking. Background Technology

[0002] DDS displacement cooking is a pulping process based on RDH cooking technology. Its core principle is to achieve the recycling of heat energy and chemicals by injecting black liquor and white liquor at different temperatures in stages. At the same time, the liquid is pushed to flow evenly in the cooking pot in a piston flow mode to ensure that the wood chips and the chemical liquor are in full contact, thereby obtaining pulp with low kappa number and high strength. However, in actual production, due to the limitations of equipment structure and operating conditions, the liquid flow is prone to deviate from the ideal state, resulting in flow deviation.

[0003] However, existing technologies have the following problems when used: Chemical agents are prone to uneven flow in the processing chamber, failing to evenly contact all parts of the wood, resulting in uneven wood treatment and affecting processing quality. When wood is placed on a support, it is easy to bump against the edge of the through hole on the support, causing damage to the edges and corners of the wood. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a DDS displacement cooking anti-deviation device, comprising: A processing box for steaming and cooking wood, wherein the processing box is provided with support components for supporting the wood; The feeding tube is rotatably installed at the bottom of the processing box. The processing box is equipped with a drive unit for driving the feeding tube to rotate. The upper end of the feeding tube passes through the bottom of the processing box and is connected to multiple sets of guide tubes to ensure that the chemical agent in the feeding tube is discharged evenly. A rotating plate is installed at the top of the feeding pipe, and a discharge hole for discharging chemical agents is opened on the outer side of the rotating plate; A fixing plate is installed on the inner side wall of the processing box, which divides the inner cavity of the processing box into upper and lower spaces. A connecting pipe for connecting the two spaces is provided on the fixing plate. A guide block is fixedly installed on the outside of the rotating plate, and the guide block is provided with an inclined part for guiding the chemical agent to the connecting pipe.

[0005] Furthermore, the support includes a shelf, which is fixedly connected to the inner wall of the processing box, and a through hole is provided on the top of the shelf.

[0006] Furthermore, the through hole has a rounded corner on the side near the top of the shelf.

[0007] Furthermore, support plates are fixedly connected to both ends of the bottom of the processing box, and mounting plates are fixedly connected to both sides of the support plates.

[0008] Furthermore, the driving component includes a worm and a worm wheel. The worm is fixedly connected between two mounting plates, and the worm wheel is fixedly connected to the lower end of the side wall of the feeding pipe. The worm and the worm wheel are meshed together.

[0009] Furthermore, a drive motor is fixedly connected to the mounting plate, the drive motor passing through the side wall of the mounting plate and fixed to the worm gear.

[0010] Furthermore, the guide tube is arc-shaped, and the discharge end of the guide tube is close to the discharge hole.

[0011] Furthermore, the shelf is located above the fixed plate.

[0012] Furthermore, an inner and outer space is formed between the rotating plate and the fixed plate, and the discharge hole connects the inner and outer spaces.

[0013] Furthermore, a discharge pipe is connected to one side of the bottom of the processing box.

[0014] Compared with the prior art, the anti-deviation device for DDS replacement cooking described in this utility model has the following advantages: 1. The drive unit drives the feeding pipe to rotate, and with the guiding effect of the arc-shaped guide pipe and the synchronous rotation of the rotating plate, the chemical agent enters the processing box cavity evenly through the discharge hole, and then is guided to the connecting pipe through the inclined part of the guide block. This solves the problem of agent flow deviation, ensures that the agent penetrates evenly and contacts all parts of the wood, and improves the uniformity of wood treatment and processing quality. 2. The rounded corners at the through holes of the support plate can buffer the contact force between the wood and the edge of the through hole when the wood is placed, avoid damage to the wood edges caused by hard impacts, and ensure the integrity of the wood after processing.

[0021] like Figures 1-5 As shown, a device for preventing diversion flow in DDS displacement cooking includes: The processing box 100 is used for steaming and cooking wood, and the processing box 100 is equipped with support components for supporting the wood. The feeding pipe 140 is rotatably disposed at the bottom of the processing box 100. The processing box 100 is provided with a driving component for driving the feeding pipe 140 to rotate. The upper end of the feeding pipe 140 passes through the bottom of the processing box 100 and is connected to multiple sets of guide pipes 142 for uniform discharge of chemical agents in the feeding pipe 140. A rotating plate 143 is provided at the top of the feeding pipe 140, and a discharge hole 144 for discharging chemical agents is provided on the outer side of the rotating plate 143. A fixing plate 170 is provided on the inner side wall of the processing box 100. The fixing plate 170 divides the inner cavity of the processing box 100 into upper and lower spaces. A connecting pipe 171 for connecting the two spaces is provided on the fixing plate 170. The guide block 180 is fixedly installed on the outside of the rotating plate 143, and the guide block 180 is provided with an inclined part 181 for guiding the chemical agent to the connecting pipe 171.

[0022] As a preferred example of this utility model, the internal support of the processing box 100 provides load-bearing capacity for the wood; the feeding pipe 140 is installed at the bottom of the processing box 100 via a rotating connection, and rotates in conjunction with the driving component on the processing box 100; the multiple sets of guide pipes 142 at its upper end can disperse the chemical agent in the pipe to the surrounding areas; the rotating plate 143 at the top rotates synchronously with the feeding pipe 140; the outer discharge hole 144 further assists in the uniform discharge of the agent; the fixed plate 170 divides the inner cavity of the processing box 100 into upper and lower areas, and the connecting pipe 171 connects the two areas; the guide block 180 and its inclined part 181 on the outer side of the rotating plate 143, with the inclined part 181 having an inclination angle of 15° to 45°, can guide the agent into the connecting pipe 171, preventing the agent from flowing out of the box and ensuring that the wood can be evenly contacted with the chemical agent, thus solving the problem of chemical agent easy to flow out of the box in traditional devices.

[0023] In the example of this application, the support includes a shelf 160, which is fixedly connected to the inner side wall of the processing box 100, and a through hole 161 is provided on the top of the shelf 160.

[0024] As a preferred example of this utility model, the through hole 161 at the top of the shelf 160 allows steam and chemical agents to pass through the shelf 160 and act on the bottom and sides of the wood, so that all parts of the wood can be in full contact with the treatment medium.

[0025] In the example of this application, a rounded corner 162 is provided on the side of the through hole 161 near the top of the shelf 160.

[0026] As a preferred example of this utility model, the rounded corner 162 can reduce the hard impact between the wood and the edge of the through hole 161 when the wood is placed, and avoid damage to the wood edges and corners that may affect the processing quality.

[0027] In the example of this application, support plates 110 are fixedly connected to both ends of the bottom of the processing box 100, and mounting plates 120 are fixedly connected to both sides of the support plate 110.

[0028] As a preferred example of this utility model, the support plate 110 serves as the supporting base of the device, and the mounting plates 120 on both sides of the support plate 110 provide mounting positions for the drive components.

[0029] In the example of this application, the driving component includes a worm gear 130 and a worm wheel 141. The worm gear 130 is fixedly connected between two mounting plates 120, and the worm wheel 141 is fixedly connected to the lower end of the side wall of the feed pipe 140. The worm gear 130 and the worm wheel 141 are meshed together.

[0030] As a preferred example of this utility model, the rotation of the worm 130 can drive the worm wheel 141 to rotate, and the worm wheel 141 can drive the feed tube 140 to rotate. Specifically, the transmission drive method of the worm 130 and the worm wheel 141 can be changed to gear meshing drive.

[0031] In the example of this application, a drive motor 131 is fixedly connected to the mounting plate 120. The drive motor 131 passes through the side wall of the mounting plate 120 and is fixed to the worm gear 130.

[0032] As a preferred example of this utility model, the drive motor 131 serves as a power source, and its output end passes through the side wall of the mounting plate 120 and is connected to the worm gear 130, thereby realizing the rotation of the feeding pipe 140.

[0033] In the example of this application, the guide tube 142 is arc-shaped, and the discharge end of the guide tube 142 is close to the discharge hole 144.

[0034] As a preferred example of this utility model, the arc-shaped design of the guide tube 142 can guide the flow direction of the agent when it flows in the tube. At the same time, the discharge end of the guide tube 142 is close to the discharge hole 144 of the rotating plate 143, so that the agent discharged from the guide tube 142 can enter the discharge hole 144 to participate in subsequent diversion and improve the uniformity of agent distribution.

[0035] In the example of this application, the shelf 160 is located above the fixing plate 170.

[0036] As a preferred example of this utility model, the wood on the shelf 160 is in the upward path of the medicine, so that the medicine comes into contact with the wood from below through the through hole 161.

[0037] In the example of this application, an inner and outer space is formed between the rotating plate 143 and the fixed plate 170, and the discharge hole 144 connects the inner and outer spaces.

[0038] As a preferred example of this utility model, the agent first enters the internal space between the rotating plate 143 and the fixed plate 170, then is evenly distributed to the external space through the rotating discharge hole 144, and then transported to the top of the fixed plate 170 through the connecting pipe 171.

[0039] In the example of this application, a discharge pipe 150 is connected to one side of the bottom of the processing box 100.

[0040] As a preferred example of this utility model, the discharge pipe 150 provides a convenient channel for the treatment of waste liquid after cooking. After cooking, the residual chemical agents in the tank can be discharged through the discharge pipe 150.

[0041] In practical use, the wood is first placed on the shelf 160, and the processing liquid is poured in for steaming. Then, the chemical agents required for steaming are injected into the feeding pipe 140, replacing the DDS. The drive motor 131 drives the worm gear 130, which is fixedly connected to it, to rotate. Because the worm gear 130 meshes with the worm wheel 141 at the lower end of the side wall of the feeding pipe 140, the rotational force of the worm gear 130 is transmitted to the worm wheel 141, thereby driving the feeding pipe 140 to rotate around its own axis. As the feeding pipe 140 continues to rotate... As the tube continues to rotate, the chemical agent inside is conveyed to multiple sets of arc-shaped guide tubes 142 connected to its upper end. The guide tubes 142 guide the flow of the agent through their arc structure. At the same time, because its discharge end is close to the discharge hole 144 opened on the outside of the rotating plate 143 at the top of the feeding tube 140, the agent can be discharged to the discharge hole 144. The rotating plate 143 rotates synchronously with the feeding tube 140, and the chemical agent enters the rotating plate 143 through the discharge hole 144 and is fixed to the inner wall of the processing box 100. The internal space formed between the plates 170, during this process, the guide block 180 fixed on the outside of the rotating plate 143 and its inclined part 181 guide the chemical agent in the internal space, directing the agent to the connecting pipe 171 on the fixed plate 170 for connecting the upper and lower spaces, avoiding the agent from flowing off course and accumulating. The chemical agent enters the upper space from the space below the fixed plate 170 through the connecting pipe 171, then permeates upward and passes through the through hole 161 on the top of the shelf 160 located above the fixed plate 170 and fixed to the upper end of the inner side wall of the processing box 100, acting evenly on the wood placed on the shelf 160. The rounded corner 162 at the through hole 161 of the shelf 160 prevents the edges of the wood from hitting the edge of the hole when it is placed. After the wood is steamed and processed, the discharge pipe 150 connected to the bottom side of the processing box 100 is opened, and the residual chemical waste liquid in the processing box 100 is discharged through the discharge pipe 150, completing the entire process.

[0042] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
