Description

Technical Field

[0001] This invention relates to the field of catalyst production technology, and in particular to a high-speed tableting system and tableting method adapted to catalysts of various specifications. Background Technology

[0002] Copper-based hydrogenation catalysts for ethylene glycol (EG) specifically refer to a class of catalysts with copper (Cu) as the main active component used in modern processes for producing ethylene glycol from coal or syngas, where the key intermediate dimethyl oxalate (DMO) is hydrogenated to ethylene glycol. Catalysts are easily impacted and worn by gas flow in industrial reactors. To prevent catalyst failure due to pulverization, copper-based hydrogenation catalysts for ethylene glycol utilize high-speed tableting to impart sufficient mechanical strength, extending the catalyst's lifespan and performance.

[0003] Existing catalyst tableting machines suffer from problems such as complex mold replacement, severe dust pollution, and low production efficiency. Traditional equipment cannot meet the production needs of catalysts of various specifications, and inadequate dust removal systems lead to raw material waste and environmental pollution. In addition, the operating interface is complex, making precise control difficult.

[0004] A dust removal and suction device for a pharmaceutical tablet press, disclosed in Chinese patent document CN107599488B, includes a moving mold and a dust removal assembly. The moving mold consists of multiple mold units, and the dust removal assembly includes a dust removal support plate, dust removal brushes, an upper roller brush, and a lower roller brush. A positioning plate is provided on one side of the dust removal support plate. The dust removal support plate has multiple circular through holes for placing tablets. Four support feet for supporting the tablets are provided at the bottom of the circular through holes. In this invention, when the moving mold moves to the dust removal assembly, an electric cylinder in the moving guide plate of the moving mold drives the moving plate to move, separating the first and second semi-circular holes. The tablets fall into the circular through holes of the dust removal assembly, and then the brushes are driven to remove dust. This invention has a simple structure, is easy to use, and has high dust removal efficiency. However, this dust removal and suction device for a pharmaceutical tablet press relies on manual or mechanical operation, which depends on the operation of cylinders and electric cylinders.

[0005] A tableting device for health food production is disclosed in Chinese patent document CN117227238A. This tableting device includes a base plate and a motor. The motor is mounted on the base plate, and a drive mechanism is located at the output end of the motor. A tableting mechanism, a feeding mechanism, and a powder removal mechanism are located on one side of the drive mechanism. During the operation of the tableting device, the feeding mechanism pushes the raw material powder into the feeding mechanism. After the feeding mechanism forms tablets, the formed tablets enter the powder removal mechanism to remove the powder adhering to the tablet surface, thereby reducing powder contamination during final packaging. Compared with the prior art, this invention can perform tableting and powder removal operations simultaneously with limited drive components, shortening the time from feeding to final packaging and improving production efficiency. The entire tableting device uses only one motor as a drive component, reducing energy consumption by reducing the number of drive components. However, the drive mechanism of this health food tableting device uses a reciprocating motion of a horizontal plate, which limits its efficiency.

[0006] A high-efficiency dust-removing tablet press disclosed in Chinese patent document CN210337055U includes a fixed frame with a dust-removing net on its inner side. Support columns are located at the four corners of the upper surface of the fixed frame, with a top cover at the top of each support column. A dustproof glass is placed between two support columns. A fixing groove is formed on the upper surface of the top cover, and a fixing shaft passes through the inner side of the fixing groove. The fan in this invention blows the drug dust on the top plate surface into the water in the lower water storage box. The dust falling into the water cannot be stirred up again, ensuring the cleanliness of the top plate for secondary use and preventing dust residue from contaminating the next tableting, thus improving the tableting quality and purity. The water inlet and drain outlet achieve a timed cleaning function. However, this high-efficiency dust-removing tablet press relies on water adsorption, which may lead to wastewater treatment problems.

[0007] To address the shortcomings of the existing technology, providing a high-speed tableting system and tableting method adaptable to catalysts of various specifications is a problem worthy of research. Summary of the Invention

[0015] Optionally, the intelligent control module also includes a pressure sensor and a vibration sensor disposed within the mold module, both of which are connected to the human-machine interface touch screen via WiFi or Bluetooth signals. When the pressure sensor and vibration sensor detect abnormal data, they automatically send alarms to the human-machine interface touch screen and the outside world, and record the abnormal production data. The automatic alarm and recording of abnormal production data facilitate timely handling of production faults, realize real-time monitoring of the production process, ensure production stability, and facilitate the tracing of abnormal issues.

By fixing the middle die 2 with the positioning pin and the pneumatic locking device, the middle die 2 can be quickly replaced within five minutes, which facilitates die replacement.

The screening machine includes a vibrating screen and a negative pressure dust removal device.

When pressure and vibration sensors detect abnormal data, they automatically send alarms to the human-machine interface touchscreen and the outside world, and record the abnormal production data. This facilitates timely handling of production faults, enables real-time monitoring of the production process, ensures production stability, and facilitates the tracing of abnormal issues.

The raw materials are quantitatively fed into each tableting station to ensure the uniformity of the raw materials, achieve precise delivery of raw materials, ensure the consistency of tableting quality at each station, and solve the problem of tableting quality differences caused by uneven delivery of raw materials and inaccurate feeding.
