Description

Technical Field

[0001] The invention belongs to the technical field of feeding equipment, and in particular relates to a device for automatically adding solid caustic soda flakes in a quantitative manner. Background Art

[0002] The traditional method of adding caustic soda flakes as a catalyst requires that the caustic soda flakes be dissolved in water first, and then the dissolved liquid caustic soda is pumped into the reactor. In order to eliminate the influence of water in the reaction, the materials mixed with the catalyst need to be vacuum dehydrated, and the dehydration process also requires appropriate temperature increase. Since the long dehydration time also affects the production cycle, in order to reduce energy consumption and shorten production time, attempts have been made to add solid caustic soda. However, manual addition is high-risk and uncontrollable. Based on this, our company has developed an automatic dosing equipment that automatically adds caustic soda flakes and performs metering to replace the existing technology. Summary of the invention

[0003] Purpose of the invention: The purpose of the present invention is to provide a device for automatically adding solid caustic soda flakes quantitatively to solve the technical problem of high and uncontrollable risks of manual feeding.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: A solid caustic soda flake quantitative automatic adding device, comprising a silo for storing caustic soda flakes and a reactor, characterized in that:

[0005] A feeding device, the feeding device includes a bracket for supporting a feeding auger and a silo and a rotary discharge valve, the feeding port of the feeding auger is connected to the silo, the feeding port of the feeding auger is connected to the rotary discharge valve, the rotary discharge valve is connected to a material storage barrel, and the material storage barrel is connected to the reactor;

[0006] A weighing sensor is installed at the bottom of the silo to weigh the silo, and the silo is fixed to the upper part of the bracket so that it is convenient to install a weighing sensor between the silo and the bracket to measure the weight of the silo;

[0007] A screen is installed at the inlet of the reactor, one end of the circulation pump is connected to the bottom of the reactor, and the other end is connected to the upper part of the material barrel.

[0008] Furthermore: the connection mode between the feeding auger inlet and the silo is a soft connection, and the connection mode between the feeding auger outlet and the rotary discharge valve is a soft connection.

[0009] Furthermore, the silo, rotary discharge valve, feeding auger, circulation pump and weighing sensor are electrically connected to the PLC controller respectively.

[0010] Compared with the prior art, the present invention has the following advantages: by adopting a combination of a feeding auger, a material holding barrel and a conveying pump, the feeding auger crushes the caustic soda flakes and sends them into the material holding barrel, the conveying pump sucks the materials in the reactor and sends them to the material holding barrel to flush and dissolve the caustic soda blocks in the material holding barrel and enter the reactor with the materials, thereby eliminating the heating and dehydration steps, reducing production energy consumption, shortening the production cycle, and having good applicability and popularization. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is the front view of the utility model; DETAILED DESCRIPTION

[0012] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0013] In the description of the invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0014] In the first embodiment of the present utility model, Figure 1 As shown, a solid caustic soda flake quantitative automatic adding device comprises a silo 1 for storing caustic soda flakes and a reaction kettle 16, characterized in that:

[0015] A feeding device, the feeding device includes a bracket 5 for supporting a feeding auger 4 and a silo 1 and a rotary discharge valve 6, the feeding auger inlet 41 is connected to the silo 1, the feeding auger outlet 42 is connected to the rotary discharge valve 6, the rotary discharge valve 6 is connected to a material storage barrel 7, and the material storage barrel 7 is connected to a reaction kettle 16;

[0016] A weighing sensor 2 is installed at the bottom of the silo 1 to weigh the silo 1;

[0017] A screen 8 is installed at the inlet of the reaction kettle 16, one end of the circulation pump 11 is connected to the bottom of the reaction kettle 16, and the other end is connected to the upper part of the material holding barrel 7;

[0018] The silo 1 is fixed to the upper part of the bracket 5 so that a weighing sensor 2 is installed between the silo 1 and the bracket 5 to measure the weight of the silo;

[0019] The connection mode between the feeding auger inlet 41 and the silo 1 is a flexible connection, and the connection mode between the feeding auger outlet 42 and the rotary discharge valve 6 is a flexible connection;

[0020] The silo 1, rotary discharge valve 6, feed auger 4, circulation pump 11 and weighing sensor 2 are electrically connected to the PLC controller respectively. The PLC controller is purchased externally and is not a core feature of the present application, so it is not drawn in the figure.

[0021] By adopting the above technical solution: the weighing sensor 2 weighs the silo 1 in real time, and the weight of the flaky caustic soda in the silo can be calculated according to the weight displayed by the weighing sensor minus the dead weight of the silo 1. During implementation, the PLC controller controls the silo 1 to open and feed the feeding auger 4, and the feeding auger 4 crushes and transports the flaky caustic soda. At the same time, the vibration of the feeding auger 4 during operation is eliminated by the soft-connected feeding auger inlet 41 and feeding auger outlet 42, and the crushed flaky caustic soda blocks enter the material holding barrel 7. When the required weight of the flaky caustic soda reaches the standard, the silo 1 and the feeding auger 4 are closed, and the circulating pump 11 is controlled by the PLC controller to start and suck the raw materials in the reactor 16 to the feeding barrel 7 to flush and dissolve the flaky caustic soda blocks in the feeding barrel 7, and the dissolved flaky caustic soda falls into the reactor 16 with the material. In this process, the screen 8 prevents the flaky caustic soda blocks from falling directly into the raw materials, thereby extending the dissolution rate.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention. These improvements should also be regarded as within the protection scope of the present invention.
