Abstract
Description
Technical Field
[0001] This utility model relates to the field of wood pulp sponge production, and specifically to a rapid dehydration equipment for wood pulp sponge production. Background Technology
[0002] Electrolysis is a crucial step in the production of wood pulp sponges. In this process, a homogeneous molded mass is injected into a foaming mold and moved to the electrolysis station for electrolysis. Upon electrolysis, cellulose xanthate decomposes to regenerate cellulose, carbon disulfide is re-precipitated, and salt crystals dissolve to form a network-like porous cellulose sponge. Simultaneously, due to dialysis and dehydration, water separates from the sponge to form an aqueous phase, while some of the dissolved salts enter the aqueous phase to form a highly concentrated sodium sulfate brine.
[0003] After the electrolysis process, the sponge enters the cleaning line for washing and dehydration. First, it is rinsed with strong and weak brine to remove salt and other impurities. Next, it undergoes bleaching with sodium hypochlorite solution to further clean the sponge. Finally, it is rinsed with circulating water to thoroughly remove any residual chemicals. After washing, the sponge undergoes physical dehydration.
[0004] Since the main component of wood pulp sponges is cellulose, these cellulose fibers form a tight network structure during the drying process. When excess water is removed, the interactions between the fibers, such as hydrogen bonds, are strengthened. For example, without dehydration, the fibers are separated by water molecules, resulting in weak interactions. After dehydration, the cellulose fibers can better entangle and interweave with each other, allowing the sponge to better recover its original shape when subjected to external pressure, thus improving its elasticity.
[0005] In addition, moisture is an essential condition for microbial growth. In a damp environment, bacteria, mold, and other microorganisms can easily proliferate in wood pulp sponges. The growth of these microorganisms not only causes the sponge to mold, deteriorate, and produce an unpleasant odor, but may also pose a threat to human health. Dehydration can effectively inhibit microbial growth and extend the shelf life of wood pulp sponges.
[0006] Patent CN205553303U discloses a wood pulp sponge extrusion device, which includes a container with an opening on one side, and hydraulic cylinders mounted on opposite side plates in the container. An extrusion plate is mounted on the end of the piston rod of each hydraulic cylinder.
[0007] The wood pulp sponge extrusion device uses two extrusion plates to simultaneously compress the wood pulp sponge. When placing the wood pulp sponge, the bottom cannot provide temporary support for it. As a result, during operation, external equipment or manual support is required to continuously support the wood pulp sponge, making the operation cumbersome and unsafe. Utility Model Content
[0008] The purpose of this invention is to provide a rapid dewatering device for wood pulp sponge production. This rapid dewatering device can stably place the wood pulp sponge that needs to be dewatered in the extrusion space before extrusion, making the extrusion operation more convenient.
[0009] To achieve the above objectives, this utility model provides a rapid dewatering device for wood pulp sponge production. The device includes a first reaction frame and a second reaction frame arranged opposite to each other. A first pressure plate capable of lateral movement is disposed inside the first reaction frame, and a second pressure plate capable of lateral movement is disposed inside the second reaction frame. A hydraulic cylinder connected to and driving the first pressure plate is disposed on the first reaction frame. An elastic reset connection is provided between the second pressure plate and the second reaction frame. A support plate extending vertically toward the second pressure plate is connected to the bottom of the first pressure plate. The upper surface of the support plate contacts the bottom surface of the second pressure plate. Multiple grooves with open ends are arranged along the length of the support plate.
[0010] Preferably, the first reaction frame is provided with a plurality of first guide holes, and a first light rod is slidably disposed in the first guide hole. The inner end of the first light rod is fixed to the first pressure plate, and the outer end is fixed to a first baffle.
[0011] Preferably, the second reaction frame is provided with a plurality of second guide holes, and a second guide rod is slidably disposed in the second guide holes. The inner end of the second guide rod is fixed to the second pressure plate, and the outer end is fixed to a second baffle. A reset spring is sleeved on the second guide rod between the second pressure plate and the second reaction frame.
[0012] Preferably, a first mounting plate is fixedly connected to the bottom of the first reaction frame on the side facing away from the second reaction frame; the first mounting plate is provided with a plurality of first mounting holes, and a plurality of first reinforcing ribs are provided between the first mounting plate and the first reaction frame.
[0013] Preferably, a second mounting plate is fixedly connected to the bottom of the second reaction frame on the side opposite to the first reaction frame; the second mounting plate is provided with a plurality of second mounting holes, and a plurality of second reinforcing ribs are provided between the second mounting plate and the second reaction frame.
[0014] Preferably, a drainage groove is provided between the first reaction frame and the second reaction frame, located below the first pressure plate, and a drainage outlet is provided at one end of the drainage groove.
[0015] Preferably, the width of the drain outlet gradually decreases along the drainage direction; the bottom height of the drainage trough gradually decreases along the drainage direction.
[0016] According to the above technical solution, this utility model provides a rapid dewatering device for wood pulp sponge production. The rapid dewatering device for wood pulp sponge production includes a first reaction frame and a second reaction frame arranged opposite to each other. A first pressure plate capable of lateral movement is provided on the inner side of the first reaction frame, and a second pressure plate capable of lateral movement is provided on the inner side of the second reaction frame. A hydraulic cylinder connected to and driving the first pressure plate is provided on the first reaction frame. An elastic reset connection is provided between the second pressure plate and the second reaction frame. A support plate extending vertically toward the second pressure plate is connected to the bottom of the first pressure plate. The upper surface of the support plate is in contact with the bottom surface of the second pressure plate. A plurality of grooves with open ends are arranged along the length of the support plate.
[0017] This rapid dewatering equipment for wood pulp sponge production has the following advantages: 1. During use, the wood pulp sponge to be dewatered is placed between the first and second pressure plates and supported by a support plate. Even when the first and second pressure plates are not applying pressure, the wood pulp sponge can maintain a relatively stable posture, making operation more convenient; 2. The hydraulic cylinder drives the first pressure plate to move and press against the second pressure plate, so that the first and second pressure plates work together to squeeze out the water from the wood pulp sponge. After squeezing, the hydraulic cylinder drives the first pressure plate to return to its original position, while the second pressure plate is reset under the action of the elastic reset connection. There is no need to add an extra set of hydraulic cylinders to drive the second pressure plate to move horizontally, resulting in lower costs; 3.

Detailed Implementation
[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0027] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.
[0028] See Figure 1-4 The rapid dewatering equipment for wood pulp sponge production shown includes a first reaction frame 1 and a second reaction frame 2 arranged opposite to each other. A first pressure plate 3 capable of lateral movement is provided on the inner side of the first reaction frame 1, and a second pressure plate 4 capable of lateral movement is provided on the inner side of the second reaction frame 2. A hydraulic cylinder 16 connected to and driving the first pressure plate 3 is provided on the first reaction frame 1. The second pressure plate 4 and the second reaction frame 2 are provided with an elastic reset connection. A support plate 19 extending vertically toward the second pressure plate 4 is connected to the bottom of the first pressure plate 3. The upper surface of the support plate 19 is in contact with the bottom surface of the second pressure plate 4. A plurality of grooves 20 with open ends are arranged along the length of the support plate 19.
[0029] By implementing the above technical solution, when in use, the wood pulp sponge that needs to be dehydrated is placed between the first pressure plate 3 and the second pressure plate 4 and supported by the support plate 19. Even when the first pressure plate 3 and the second pressure plate 4 are not applying pressure to the wood pulp sponge, the wood pulp sponge can maintain a relatively stable posture, making the operation more convenient. The first pressure plate 3 is moved and pressed onto the second pressure plate 4 by the hydraulic cylinder 16, so that the first pressure plate 3 and the second pressure plate 4 work together to squeeze out the water in the wood pulp sponge. After the squeezing is completed, the hydraulic cylinder 16 drives the first pressure plate 3 to return to its original position, while the second pressure plate 4 is reset under the action of the elastic reset connection. There is no need to add an extra set of hydraulic cylinder 16 to drive the second pressure plate 4 to move horizontally, which reduces the cost. By setting multiple grooves 20 on the support plate 19, the water squeezed out at the bottom can be discharged along the grooves 20, which increases the dehydration effect and prevents water from accumulating at the bottom. The first reaction frame 1 and the second reaction frame 2 are non-fixed connected, and the installation spacing can be adjusted according to the wood pulp sponge of different thicknesses.
[0030] In this embodiment, the first reaction frame 1 is provided with a plurality of first guide holes, and a first guide rod 14 is slidably disposed in the first guide hole. The inner end of the first guide rod 14 is fixed to the first pressure plate 3, and the outer end is fixed to a first baffle 15. For example, four first guide holes and four first guide rods 14 are provided in a matrix distribution. The hydraulic cylinder 16 is located at the center of the four first guide holes to increase the stability of the first baffle 15.
[0031] In this embodiment, the second reaction frame 2 is provided with multiple second guide holes, and a second guide rod 17 is slidably disposed in the second guide holes. The inner end of the second guide rod 17 is fixed to the second pressure plate 4, and the outer end is fixed to a second baffle 18. A return spring 13 is sleeved on the second guide rod 17 between the second pressure plate 4 and the second reaction frame 2. For example, four second guide holes and four second guide rods 17 are provided in a matrix distribution to increase the stability of the second baffle 18. At the same time, when the return spring 13 is in its normal state, the second baffle 18 is in contact with and limited to the outer side of the second reaction frame 2. When the return spring 13 is under pressure, the second baffle 18 separates. The elastic coefficient of the return spring 13 is determined according to the pressure that the wood pulp sponge can withstand, so that the wood pulp sponge can be squeezed and dehydrated normally. To avoid large displacement of the second pressure plate 4, the elastic coefficient should not be too small.
[0032] In this embodiment, a first mounting plate 5 is fixedly connected to the bottom of the first reaction frame 1 on the side facing away from the second reaction frame 2; the first mounting plate 5 is provided with a plurality of first mounting holes 9, and a plurality of first reinforcing ribs 7 are provided between the first mounting plate 5 and the first reaction frame 1. With this arrangement, the first reaction frame 1 forms a more stable structure, and it can be installed at the corresponding work position by bolts passing through the first mounting holes 9.
[0033] In this embodiment, a second mounting plate 6 is fixedly connected to the bottom of the second reaction frame 2 on the side facing away from the first reaction frame 1; the second mounting plate 6 is provided with a plurality of second mounting holes 10, and a plurality of second reinforcing ribs 8 are provided between the second mounting plate 6 and the second reaction frame 2. This arrangement makes the second reaction frame 2 form a more stable structure, and it can be installed at the corresponding workstation position by bolts passing through the second mounting holes 10.
[0034] In this embodiment, a drainage trough 11 is provided below the first pressure plate 3 between the first reaction frame 1 and the second reaction frame 2. One end of the drainage trough 11 is provided with a drain outlet 12. The other end of the drainage trough 11 relative to the drain outlet 12 is closed and protrudes from the first reaction frame 1 and the second reaction frame 2 to collect the water squeezed out of the wood pulp sponge and discharge it through the drain outlet 12 to a designated collection location for centralized treatment.
[0035] In this embodiment, the width of the drain outlet 12 gradually decreases along the drainage direction; the bottom height of the drainage trough 11 gradually decreases along the drainage direction. This design allows for faster drainage of accumulated water and enables the drainage to be collected and discharged.
[0036] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0037] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
[0038] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
