TECHNICAL FIELD

[0001] The utility model relates to the technical field of engine mixer, concretely relates to a single fuel engine mixer. BACKGROUND

[0002] The engine mixer is an important component in the air intake system of the engine, which mainly mixes natural gas with air and adjusts the proportion of the mixture to ensure that the engine can operate efficiently and stably. According to the different types of fuel, the engine mixer can be divided into single fuel engine mixer and dual fuel engine mixer. The single fuel engine mixer refers to the engine component that only uses natural gas as the engine fuel without using other fuels. The single fuel engine mixer can mix natural gas with air to form combustible mixture for engine combustion.

[0003] However, the existing single fuel engine mixer lacks a structure for filtering air or natural gas before it enters the inside of the mixer, and does not have the function of re-filtering the mixed gas, resulting in poor quality of the mixed gas. Therefore, we propose a single fuel engine mixer. SUMMARY

[0004] In view of the problems in the prior art, the utility model provides a single fuel engine mixer. The single fuel engine mixer has a structure for filtering air or natural gas before it enters the inside of the mixer, and can re-filter the mixed gas before it enters the engine, thereby effectively improving the quality of the mixed gas.

[0005] The utility model solves the technical problems by adopting the technical scheme of a single fuel engine mixer, which comprises a mixer main body, an air inlet and an air outlet arranged at both ends of the mixer main body, a mixer throat pipe connected to the top of the mixer main body, an installation shell fixed to the top of the mixer throat pipe, a filter element installed in the installation shell through an installation groove, and a rubber plug embedded in the filter element.

[0006] A mixing chamber for mixing natural gas with air is formed in the inside of the mixer main body. A first filter screen is arranged at one end of the mixing chamber and inside the air inlet, and a second filter screen is arranged at the other end of the mixing chamber and inside the air outlet.

[0007] Through the above technical scheme, natural gas enters the mixing chamber through the air inlet. The first filter screen can remove solid impurities, part of liquid impurities and other small particle matters in the natural gas, and the filtered natural gas is more pure, which helps to improve the uniformity of the mixed gas.

[0008] By reducing the caliber of the throat, the air and the natural gas can generate higher flow rate in the mixer throat, and the interaction between the air and the natural gas is enhanced due to the pressure drop and the flow rate increase in the mixer throat, thereby promoting the mixing of the air and the natural gas, and the filter element inside the mixer throat can filter the air, which can effectively remove the particulate matters, dust, moisture and other impurities in the air, thereby effectively improving the purity of the air.

[0009] The second filter screen can filter the mixed gas again before the mixed gas enters the engine through the exhaust port, and the filtered mixed gas is more pure, and the pure mixed gas can ensure more sufficient combustion, thereby improving the combustion efficiency of the engine and reducing the maintenance and replacement costs.

[0010] Specifically, a first bolt hole is formed around the top of the filter element, a fixing bolt is arranged outside the filter element, and a second bolt hole corresponding to the first bolt hole is formed in the top of the mounting shell and outside the mounting groove.

[0011] By adopting the above technical scheme, the filter element and the mounting shell can be detachably connected through the fixing bolt, the first bolt hole and the second bolt hole.

[0012] Specifically, mounting plates are arranged at both ends of the mixer body, and mounting holes are formed in the mounting plates.

[0013] Specifically, a throat is formed in one side of the mixer body.

[0014] By adopting the above technical scheme, the throat can communicate the mixer throat with the mixing cavity, so that the air can enter the mixing cavity through the mixer throat.

[0015] Specifically, the rubber plug is made of silica gel material.

[0016] The utility model discloses the beneficial effects of the following:

[0017] (1) the single fuel engine mixer of the utility model, natural gas enters the mixing cavity through the air inlet, and the first filter screen can remove the solid impurities, part liquid impurities and other small particulate matters in the natural gas, and the filtered natural gas is more pure, which helps to improve the uniformity of the mixed gas.

[0018] (2) The single fuel engine mixer, by reducing the caliber of the throat, can make the air and natural gas produce a higher flow rate in the mixer throat pipe, and due to the pressure reduction and flow rate increase, the interaction between the air and natural gas is enhanced, thereby promoting the mixing of the air and natural gas, and meanwhile, the filter element inside the mixer throat pipe can filter the air, and can effectively remove the particulate matter, dust, moisture and other impurities in the air, and can effectively improve the purity of the air.

[0019] (3) The single fuel engine mixer, before the mixed gas enters the engine through the exhaust port, the second filter screen can filter the mixed gas again, and the filtered mixed gas is more pure, and the pure mixed gas can ensure more sufficient combustion, thereby improving the combustion efficiency of the engine and reducing the maintenance and replacement cost.

[0028] The inside of mixer main part 1 is set up with the mixing cavity 11 of being convenient for natural gas and air to mix, one filter screen 12 is arranged in the inside of air inlet 2 at the one end of mixing cavity 11, and two filter screens 13 are arranged in the inside of exhaust port 3 at the other end of mixing cavity 11.

[0029] When using, natural gas enters mixing cavity 11 through air inlet 2, one filter screen 12 can remove the solid impurities and part liquid impurities etc.

[0030] Fine particulate matter removal, the natural gas after filtration is more pure, and it helps to improve the uniformity of mixed gas,

[0031] By reducing the caliber of the throat, air and natural gas can produce higher flow rate in mixer throat pipe 4, due to the pressure drop and flow rate increase, the interaction between air and natural gas is enhanced, thereby promoting the mixing of air and natural gas, at the same time, the filter core 9 in the inside of mixer throat pipe 4 can filter air, which can effectively remove the particulate matter, dust, moisture and other impurities in air, and can effectively improve the purity of air,

[0032] Before mixed gas enters engine through exhaust port 3, two filter screens 13 can filter mixed gas again, and the filtered mixed gas is more pure, and the pure mixed gas can ensure more sufficient combustion, thereby improving the combustion efficiency of engine and reducing maintenance and replacement cost.

[0033] Exemplarily, as shown in the figure, Figure 4 As shown, a number of bolt holes 15 are formed around the top of filter core 9, a fixing bolt 10 is arranged on the outside of filter core 9, and a number of bolt holes 16 corresponding to the number of bolt holes 15 are formed on the top of installation shell 8 and around installation groove 17.

[0034] When using, the filter core 9 and installation shell 8 can be detachably connected through the fixing bolt 10, the number of bolt holes 15 and the number of bolt holes 16.

[0035] Exemplarily, as shown in the figure, Figure 1 , Figure 2 , Figure 3As shown, the two ends of the mixer body 1 are provided with mounting plates 6, and mounting holes 7 are formed in the mounting plates 6.

[0036] In use, the mounting plates 6 and the mounting holes 7 facilitate the installation of the mixer body 1.

[0037] As shown, Figure 3 As shown, a throat 14 is formed in one side of the mixer body 1.

[0038] In use, the throat 14 facilitates the communication of the mixer throat 4 with the mixing chamber 11, so that air can enter the mixing chamber 11 through the mixer throat 4.
