Description

High-sealing shell of urea filling machine

Technical Field

The utility model relates to a high-tightness shell of a urea filling machine, and belongs to the technical field of urea filling equipment.

Background

The urea solution for diesel vehicle is also called automobile urea, and consists of 32.5% of high-purity urea and 67.5% of deionized water, and the crystallization phenomenon occurs at the temperature of minus 11 ℃. The automobile urea has the function of chemically reacting with oxynitride in the tail gas of the diesel vehicle to generate nontoxic nitrogen and water, thereby reducing the emission of toxic gas in the tail gas and reducing pollution.

A urea filling machine placed at a filling station generally has a liquid storage tank communicated with a filling device through a pipeline for storing urea solution. The solution heating device of the existing liquid storage tank is too complex and uneven in heating, and the local crystallization phenomenon still occurs in the tank body; even if the pipeline of the tank body communicated with the filling device is protected against freezing and heat preservation, the urea solution in the pipeline is still when the filling is stopped, and the problem of crystallization and blockage still occurs along with the gradual reduction of the temperature.

Disclosure of Invention

The utility model aims to overcome the defects and provide the high-sealing shell of the urea filling machine, which has the advantages that the urea solution in the tank body is uniformly heated, and the pipeline between the tank body and the filling device is not crystallized and blocked.

The purpose of the utility model is realized as follows:

the high-sealing shell of the urea filling machine comprises a box body, a heating device arranged at the bottom of the box body, a discharge pipe penetrating through the inside of the box body from left to right, and a suction pipe and a filling pipe which are arranged in the middle of the right end of the box body and are communicated with the box body.

According to the high-tightness shell of the urea filling machine, the bottom of the right end of the box body is also provided with the blow-off pipe communicated with the box body.

The high-sealing shell of the urea filling machine is characterized in that a manhole is formed in the top of the box body.

The utility model relates to a high-tightness shell of a urea filling machine.

The utility model relates to a high-tightness shell of a urea filling machine.A reinforcing plate is arranged on the bottom surface of a box body and corresponds to the blanking position of a filling pipe.

According to the high-sealing shell of the urea filling machine, the box body is made of stainless steel or metal titanium.

Compared with the prior art, the utility model has the beneficial effects that:

the heating device arranged at the bottom of the tank body utilizes the convection heat transfer of the urea solution to ensure the spontaneous circulation flow of the urea solution and ensure the uniform temperature of the urea solution; set up the discharging pipe inside the box, utilize the temperature of the inside urea solution of box to keep warm, guarantee that the urea solution in the discharging pipe can not take place the condition that the crystallization blockked up even static not when flowing, need not to take extra heat preservation antifreeze measures to the discharging pipe.

Detailed Description

Referring to fig. 1-4, the high-sealing shell of the urea filling machine comprises a box body 1, a heating device 2 arranged at the bottom of the box body 1, discharge pipes 3 penetrating through the box body 1 from left to right, a suction pipe 4 and a filling pipe 5 arranged in the middle of the right end of the box body 1 and communicated with the box body 1.

Further, a sewage discharge pipe 6 communicated with the box body 1 is further arranged at the bottom of the right end of the box body 1.

Further, a manhole 7 is arranged at the top of the box body 1.

Further, the heating device 2 is a finned heat dissipation pipe or a heat exchanger.

Furthermore, a reinforcing plate 8 is arranged on the bottom surface of the box body 1 corresponding to the blanking position of the filling pipe 5.

Further, the box body 1 is made of stainless steel or metal titanium.

When in use, the urea pump is arranged on the right end surface of the box body 1, the feed inlet of the urea pump is connected with the material suction pipe 4, and the discharge outlet of the urea pump is connected with the right end of the discharge pipe 3; connecting the left end of the discharge pipe 3 with a urea filling machine; urea solution is injected into the box body 1 through the filling pipe 5, and a reinforcing plate 8 is arranged at a scouring position where the urea solution enters the box body 1 from the filling pipe 5, so that the box body 1 at the scouring position is prevented from being scoured and worn, and the service life of the box body 1 is prolonged; the heating device 2 ensures that the urea solution in the box body 1 keeps normal temperature, and prevents the urea solution in the box body 1 from crystallizing; because the discharge pipe 3 is arranged in the box body 1, the phenomenon of crystal blockage can not occur when the urea solution sucked out by the urea pump passes through the discharge pipe 3; the manhole 7 at the top of the box body 1 is convenient for workers to overhaul and maintain the interior of the box body 1; the filth inside the case 1 is discharged through the filth discharge pipe 6.
