Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pharmaceutical stirring tanks, in particular to a mobile air replacement device for a pharmaceutical stirring tank. Background Art
[0002] During the mineral processing process, organic agents such as xanthate and amine black are added to improve economic and technical indicators. However, after dilution, a small amount of mineral processing agents remain inside the agent mixing tank. When the agents evaporate, they produce pungent gases, resulting in poor air quality. Entering the agent mixing tank is a confined space operation. In addition, handling equipment failures often involves hot work. Volatile gases are extremely prone to spontaneous combustion when exposed to fire, which can easily cause flash explosions and fire accidents. To ensure operational safety, gas replacement is required before entering the tank. The traditional method is to place an axial flow fan outside the agent mixing tank for forced ventilation. This method is far away from the operation point and only uses air supply. The air replacement efficiency is low, affecting the overall progress of fault handling. Utility Model Content
[0003] In response to the above technical problems, the utility model provides a mobile air replacement device for a pharmaceutical stirring tank, which is used to solve the problem that the ventilation method of the pharmaceutical stirring tank is far away from the operation point and the air replacement efficiency is low.
[0004] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows:
[0005] A mobile air replacement device for a pharmaceutical mixing tank includes a bidirectional fan. The air outlet of the bidirectional fan is connected to a corrugated air pipe through a sealing component. The free end of the corrugated air pipe is located in the pharmaceutical mixing tank. A filter is installed at the air outlet of the bidirectional fan.
[0006] Furthermore, the sealing assembly consists of a sealing plate and a sleeve. The sealing plate is installed on the exhaust port of the bidirectional fan through fasteners. A through hole is opened on the sealing plate, and a sleeve is provided on the through hole. The corrugated air pipe is fastened to the sleeve through a pipe clamp.
[0007] Furthermore, a support rod is installed on the free end of the corrugated air pipe.
[0008] Furthermore, a bracket is provided at the bottom of the bidirectional blower, and universal wheels are installed on the legs of the bracket.
[0009] Furthermore, the universal wheel is provided with a foot brake.
[0010] Furthermore, the sealing plate is made of steel plate with a thickness of 2-5 mm.
[0011] Furthermore, a push rod is provided on one side of the bracket.
[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention stretches and extends the corrugated air pipe, places the free end of the corrugated air pipe at the working point in the pharmaceutical mixing tank, starts the two-way fan, and adopts a pumping and discharging method to extract and discharge the volatile gas in the pharmaceutical mixing tank, thereby improving the efficiency of air replacement. The discharged gas can be purified and filtered through the filter to avoid polluting the environment, thereby improving the air quality in the confined space, and can effectively solve the problems of poor air quality and low gas replacement efficiency when working inside the confined space.

[0018] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.
[0019] A mobile air replacement device for a pharmaceutical mixing tank includes a bidirectional blower 1, the air outlet of which is connected to a corrugated air tube 3 via a sealing assembly. The free end of the corrugated air tube 3 is located within the pharmaceutical mixing tank, and a filter 4 is installed at the air outlet of the bidirectional blower 1. The utility model extends the corrugated air tube 3, places the free end of the corrugated air tube 3 at an operating point within the pharmaceutical mixing tank, and activates the bidirectional blower 1. This device extracts and exhausts volatile gases from the pharmaceutical mixing tank using a simultaneous extraction and exhaust method, thereby improving the efficiency of air replacement. The exhausted gases can then be purified and filtered through the filter 4 to avoid environmental pollution.
