Embodiment

[0023] Such as Figure 1-9 As shown, it is a metering device for a catalyst for the preparation of alkylphenol disclosed in the present invention, which includes a silo 100 containing the catalyst. The silo 100 is provided with a feed port and a discharge port. Above, a metering and holding assembly 200 for containing the catalyst is provided at the discharge port, and a feeding assembly 300 is arranged on the metering and holding assembly 200, and the feeding assembly 300 sends the catalyst in the metering and holding assembly 200 to the reaction device (not shown in the figure). shown) for delivery, and a pressing assembly 400 is arranged in the feed bin 100 . The catalyst is put into the feed bin 100 from the feed port, and the catalyst enters the metering and holding assembly 200 from the discharge port. The catalyst in 200 is put into the production reaction device, and the pressing assembly 400 compacts the catalyst in the metering container assembly 200 to ensure the c...

[0027] When the material filling port 206 on the turntable 213 is located below the discharge port, the pressing assembly 400 presses the catalyst into the material filling port 206, the turntable 213 rotates 180 degrees, and the ring gear 301 also rotates 180 degrees at the same time, and the turntable 213 stops rotating at this time , another charging port 206 is loaded with catalyst, and the ring gear 301 continues to rotate, and the toggle tooth 306 on the ring gear 301 rotates the baffle plate 204 through the driven teeth 212. At this time, the baffle plate 204 is not in contact with the charging port. 206 coincides, the catalyst in the material holding port 206 falls into the reaction device, the ring gear 301 continues to rotate, due to the limitation of the slip groove 207, the baffle plate 204 cannot continue to rotate, and there is extrusion between the toggle tooth 306 and the driven tooth 212 , the toggle tooth 306 stops rotating after bypassing the driven tooth 212...

Abstract

The invention relates to a metering device for a catalyst used in the preparation of alkylphenol, which belongs to the technical field of metering equipment, and comprises a silo containing a catalyst. The silo is provided with a material inlet and a material outlet. Above the feed port, the outlet is provided with a metering and filling assembly for containing the catalyst, and the metering and holding assembly is provided with a feeding assembly, and the feeding assembly sends the catalyst in the metering and holding assembly to the reaction device Putting in, a pressing assembly is arranged in the feed bin. The catalyst is put into the bin from the feed port, and the catalyst enters the metering and holding assembly from the outlet, and the pressing assembly will compact the catalyst that enters the metering and holding assembly. In the production reaction device, the pressing component compacts the catalyst in the metering and holding component to ensure the compactness of the catalyst in the metering and holding component, thereby ensuring a stable dosage of the catalyst.

Description

technical field [0001] The invention relates to the technical field of metering equipment, in particular to a metering device for a catalyst for preparing alkylphenols. Background technique [0002] Catalysts in chemical reactions can change the chemical reaction rate of reactants (increase or decrease) without changing the chemical equilibrium. In the preparation of alkylphenols, a large number of catalysts are usually used, and the long-term stable dosage of catalysts directly determines the quality and production efficiency of the product. When powdery or granular catalysts are used, due to compactness, the catalyst feeding device in the prior art cannot stabilize the ratio of catalysts, which affects product quality and production efficiency. Aiming at the problems existing in the prior art, we propose a metering device capable of stabilizing the dosage ratio of the catalyst for the preparation of alkylphenols. Contents of the invention [0003] The present invention...
