Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0016] The automatic regulating device for dense-phase filling flow of the present invention comprises: PLC1, an ultrasonic range finder connected with PLC1, a flow regulating bottom plate 2, a push rod 3 and a stepping motor 4. The ultrasonic range finder is installed towards the loaded catalyst surface, and is used to measure the height of the loaded catalyst. Such as figure 1 and figure 2 As shown, multiple groups of flow regulating bottom plates 2 are arranged at the outlet 51 below the catalyst lower hopper 5, and each group of flow regulating bottom plates 2 is fan-shaped in which multiple pieces are superimposed and connected in sequence, wherein the top or bottom fan-shaped plate and ...

Abstract

The invention discloses a dense-phase loading flow automatically-adjusting device. The dense-phase loading flow automatically-adjusting device is characterized by comprising one or more groups of flow adjusting bottom plates which are arranged at the discharging port under a catalyst feeding hopper, every group of flow adjusting plates are multiple sector plates which are overlapped and sequentially connected, wherein the top sector plate or the bottom sector plate is connected with a push bar, and the push bar is driven by a motor to move. According to the dense-phase loading flow automatically-adjusting device, a user can set density and loading height per unit time on a touch screen as required, measure the loading height and compare the loading height with the set target value by controlling a supersonic wave distance meter through a PLC (programmable logic controller) and accordingly adjust the feeding flow and the loading speed in real time.

Description

[0001] technical field [0002] The invention relates to an automatic adjustment device for dense-phase filling flow, which belongs to the technical field of petrochemical equipment. Background technique [0003] In various related industries such as petroleum and chemical industry, there are certain requirements for the catalyst loaded in the reactor. Usually, the loaded catalyst needs to reach a certain packing density to meet the working needs of the reactor. In the prior art, the packing density is usually constant and cannot be adjusted in real time according to the reaction speed. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art, and provide an automatic adjustment device for dense-phase filling flow, which can adjust the amount of catalyst feeding, and further adjust the feeding flow and loading speed of the catalyst in real time. [0005] In order to solve the above technica...
