[0009] A box body is provided with an installation space inside.

[0010] A scraping structure is arranged in the box body and includes a driving assembly and a scraper assembly. The driving assembly drives the scraper assembly to ascend and descend.

[0011] The inside of the pulp washing machine body is rotatably connected with a pair of rollers through a roller shaft. The outer wall of the roller is rotatably connected with a filter screen in contact with the top of the scraper assembly. The pulp washing mechanism is installed at the front end of the roller.

[0012] The high-speed pulp washing machine for papermaking comprises a washing machine body, a supporting leg is arranged at the bottom of the washing machine body to keep the machine stable and run. A pulp washing mechanism is arranged in the washing machine body to clean and process the pulp. In addition, a scraping mechanism is arranged to scrape off the excess pulp on the pulp washing mechanism to avoid affecting the operation of the pulp washing mechanism. The scraping mechanism comprises a box body, an installation space is arranged in the box body to install a scraping structure, which comprises a driving assembly and a scraper assembly. The driving assembly is used to drive the scraper assembly to ascend and descend to facilitate contact with the filter screen.

[0013] Through the design of multiple scrapers, the pulp attached to the filter screen can be more effectively scraped off, improving the scraping efficiency and avoiding the influence of the accumulated pulp on the transmission components of the pulp washing mechanism.

[0014] Further, the pulp washing mechanism comprises:

[0015] A chain wheel is arranged on each roller shaft, and a chain is connected between the two chain wheels.

[0016] A baffle is arranged above the chain and connected with the inner wall of the washing machine body to block the pulp from falling on the chain.

[0017] The side of the box body is further provided with a discharge port, and an auxiliary scraper is arranged on the discharge port to contact the filter screen.

[0018] The pulp washing mechanism comprises a chain wheel, a chain and a baffle, a chain wheel is arranged on each roller shaft, and a chain is connected between the two chain wheels to enable the roller shafts to rotate synchronously, thereby driving the filter screen and the pulp attached thereto to undergo a continuous and stable cleaning process. A baffle is arranged above the chain and connected with the inner wall of the washing machine body. The baffle can block the pulp from falling directly on the chain, preventing the pulp from accumulating and hardening on the chain and thereby affecting the normal operation of the chain and the overall performance of the pulp washing machine.

[0019] Meanwhile, a discharge port is arranged on one side of the box body, and an auxiliary scraper is arranged on the discharge port to contact the filter screen. The main function of the auxiliary scraper is to help completely scrape off the residual pulp on the filter screen and guide the pulp to be discharged out of the pulp washing machine through the discharge port, thereby improving the scraping efficiency and ensuring the cleanliness of the filter screen to provide better conditions for subsequent pulp processing.

[0020] Further, the scraper assembly comprises:

[0021] The first scraper comprises a first plate body, a first sleeve rod arranged at the bottom of the first plate body and a first power rod threadedly connected with the first sleeve rod.

[0022] The second scraper comprises a second plate body, a second sleeve rod arranged at the bottom of the second plate body and a second power rod threadedly connected with the second sleeve rod.

[0023] The first power rod and the second power rod are connected with the driving assembly, and the driving assembly can simultaneously drive the first power rod and the second power rod to lift.

[0024] The scraper assembly mainly comprises a first scraper and a second scraper, which operate synchronously and achieve a more efficient scraping effect. A first set of rods is installed at the bottom of the first plate body and is threadedly connected with the first power rod. The height of the first scraper can be adjusted by rotating the first power rod. The second plate body is similar to the first plate body. A second set of rods is installed at the bottom of the second plate body and is used to connect and support the second power rod. The second set of rods is threadedly connected with the second power rod. The height of the second scraper can be adjusted by rotating the second power rod. The driving assembly is used to provide lifting power and control the lifting of the first power rod and the second power rod. The driving assembly can simultaneously drive the first power rod and the second power rod to lift, and the lifting process is stable and synchronous.

[0025] During the operation of the pulp washing machine, the driving assembly receives a control instruction and simultaneously drives the first power rod and the second power rod to lift through the transmission mechanism. With the lifting of the power rods, the first scraper and the second scraper move up and down accordingly, thereby contacting the filter screen and scraping off the residual pulp on the filter screen. The design of the double scrapers makes the scraping process more efficient and improves the processing efficiency of the pulp.

[0026] Further, the driving assembly comprises:

[0027] A driving motor is horizontally arranged in the installation space, and a driving gear is arranged on the output shaft of the driving motor;

[0028] A first face gear is horizontally arranged in the installation space and connected with the first power rod;

[0029] A second face gear is horizontally arranged in the installation space and spaced apart from the first face gear, and the second face gear is connected with the second power rod;

[0030] The driving gear is engaged with the first face gear and the second face gear.

[0031] The driving assembly, as the power source for lifting the scraper assembly, adopts a combination of a driving motor, a driving gear, a first face gear, and a second face gear. The driving motor is horizontally arranged in the installation space, and a driving gear is arranged on the output shaft of the driving motor, which is used to transmit the rotating power of the motor to other gears. The teeth of the driving gear are engaged with the first face gear and the second face gear. The first face gear is horizontally arranged in the installation space and connected with the first power rod. The second face gear is also horizontally arranged in the installation space and spaced apart from the first face gear. Through the engagement with the driving gear, the two gears can rotate under the driving of the driving gear, thereby driving the first scraper to lift through the first power rod and driving the second scraper to lift through the second power rod.

[0032] By adopting the design of face gear, vertical transmission of power is realized, so as to effectively utilize the vertical height in the installation space, not only avoiding the problem of space waste in the traditional transmission mode, but also making the structure of the whole driving assembly more compact and reasonable. In addition, since the driving gear is engaged with the first face gear and the second face gear at the same time, synchronous transmission of power is realized. Not only the transmission efficiency is improved, but also the synchronization and stability of the lifting of the first scraper and the second scraper are ensured, and the energy loss in the transmission process is also reduced.

[0033] Further, the box body is provided with two through holes through which the power rod and the second power rod pass, and sealing rings are arranged in the through holes.

[0034] The two through holes correspond to the positions of the first power rod and the second power rod respectively, and the size is slightly larger than the diameter of the power rod to ensure that the power rod can pass through smoothly. In order to avoid impurities such as paper pulp entering the inside of the box body through the through hole, a sealing ring is installed in each through hole. The sealing ring is made of wear-resistant and corrosion-resistant material, which can tightly fit the surface of the power rod, effectively prevent the intrusion of impurities such as paper pulp, not only keep the inside of the box clean, but also prolong the service life of the equipment.

[0035] Further, the first sleeve rod and the second sleeve rod are provided with guide ribs, and the box body is provided with guide frames matched with the guide ribs.

[0036] The guide ribs are installed on the first sleeve rod and the second sleeve rod, and the ribs extend along the length direction of the sleeve rod.

[0037] The beneficial effects of the present application are:

[0038] 1. By designing multiple scrapers, the efficiency of scraping the pulp attached to the filter screen is improved, and the influence of accumulated paper pulp on the transmission components of the pulp washing mechanism is avoided.

[0039] 2. By adopting the design of face gear, vertical transmission of power is realized, so as to effectively utilize the vertical height in the installation space, not only avoiding the problem of space waste in the traditional transmission mode, but also making the structure of the whole driving assembly more compact and reasonable.

[0040] 3. Since the driving gear is engaged with the first face gear and the second face gear at the same time, synchronous transmission of power is realized. Not only the transmission efficiency is improved, but also the synchronization and stability of the lifting of the first scraper and the second scraper are ensured, and the energy loss in the transmission process is also reduced.
