Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of constant-pressure water supply, in particular to a constant-pressure water supply device for urban areas. Background Art
[0002] Constant pressure water supply is a water supply method used in hydraulic systems. It maintains a constant pressure, balancing water supply and consumption. This ensures more water is supplied when water usage is high, and less water is supplied when water usage is low, thereby improving water quality. Water supply is an essential component of life in urban areas, so a constant pressure water supply device is essential.
[0003] Chinese patent publication CN217679372U discloses an integrated water supply device comprising a housing, a first tank body fixedly mounted within the housing, a motor fixedly mounted on the top of the housing body, a rotating shaft fixedly connected to the output end of the motor, a plurality of stirring rods symmetrically fixedly mounted on the outer wall of the rotating shaft, a first extrusion rod fixedly connected to the bottom of the rotating shaft, two telescopic cylinders symmetrically fixedly mounted on the inner wall of the first tank body, a second extrusion rod compatible with the first extrusion rod fixedly connected to the top of each of the telescopic cylinders, a conical spring fixedly connected to the bottom of the second extrusion rod, the bottom of the conical spring fixedly connected to the first tank body, and the conical spring sleeved on the outside of the telescopic cylinder. The first extrusion rod, the second extrusion rod, and the conical spring cooperate to rotate the rotating shaft, thereby driving the stirring rods to rotate, thereby accelerating the mixing of water and solution. The conical spring also reverses, driving the second extrusion rods to rotate in the opposite direction, thereby further disrupting the water content within the first tank body.
[0004] The disadvantage of the above-mentioned disclosed solution is that: although the second extrusion rod can rotate in the opposite direction while the stirring rod rotates, the second extrusion rod can only rotate at the bottom of the first tank body, resulting in a smaller range of reverse stirring of the second stirring rod, thereby reducing the speed of sufficient mixing of the liquid medicine and water. Utility Model Content
[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a constant pressure water supply device for urban areas. By rotating the inner mixing drum and the outer mixing drum in opposite directions, the stirring range is increased, which can effectively solve the problems in the background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a constant-pressure water supply device for an urban area, comprising a mixing box, a medicine liquid tank connected to the interior of the mixing box is provided on the top of the mixing box, a water storage barrel connected to the interior of the mixing box is provided on the bottom of the mixing box, a mixing chamber is provided in the mixing box, an inner mixing drum and an outer mixing drum are provided in the mixing chamber, the outer mixing drum is sleeved on the outside of the inner mixing drum, and a plurality of stirring rods are evenly provided on the inner mixing drum and the outer mixing drum respectively; a driving assembly is provided on the mixing box for simultaneously driving the inner mixing drum and the outer mixing drum to rotate in opposite directions.
[0007] Furthermore, the drive assembly includes a motor, which is fixedly arranged on the top of the mixing box. An installation cavity is also opened in the mixing box. The output end of the motor extends into the installation cavity and is fixedly provided with a connecting rod. The connecting rod extends into the mixing chamber and is fixedly connected to the inner mixing drum. A sleeve is rotatably arranged in the installation cavity. The sleeve is sleeved on the outside of the connecting rod. The sleeve extends into the mixing chamber and is fixedly connected to the outer mixing drum. A first bevel gear is fixedly sleeved on the connecting rod, and a third bevel gear is fixedly sleeved on the sleeve. A second bevel gear is rotatably arranged in the installation cavity, and the second bevel gear is respectively engaged with the first bevel gear and the third bevel gear.
[0008] Furthermore, the liquid medicine tank is connected to the interior of the stirring chamber through a connecting pipe, and a baffle is fixedly mounted on the sleeve. When the baffle rotates, it cooperates with the connecting pipe to intermittently flow liquid medicine into the stirring chamber.
[0009] Furthermore, the mixing box is connected to the water storage barrel through a delivery pipe, a control valve is provided on the delivery pipe, and a water outlet pipe is provided at the bottom of the water storage barrel.
[0010] Furthermore, a plurality of through holes are evenly formed on the inner mixing drum and the outer mixing drum.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] Since a plurality of stirring rods are evenly arranged on the inner mixing drum and the outer mixing drum respectively, and a driving assembly is provided on the mixing box which drives the inner mixing drum and the outer mixing drum to rotate in opposite directions at the same time, when the water in the mixing box needs to be disinfected, the motor is started, the motor drives the connecting rod to rotate, the connecting rod drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the third bevel gear to rotate, the third bevel gear drives the sleeve to rotate, the connecting rod also drives the inner mixing drum to rotate, the inner mixing drum drives the stirring rod on its outer surface to rotate, and the sleeve drives the outer mixing drum to rotate at the same time. Since the sleeve rotates in opposite directions to the connecting rod, the stirring rod on the outer surface of the outer mixing drum rotates in opposite directions to the stirring rod on the outer surface of the inner mixing drum, thereby fully stirring the water and the liquid medicine, and increasing the stirring range, thereby accelerating the mixing between the liquid medicine and the water.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] See also Figure 1-Figure 3 The utility model provides a technical solution: a constant pressure water supply device for urban areas, comprising a mixing box 1, wherein a mixing chamber and an installation chamber are provided in the mixing box 1, the installation chamber is located above the mixing chamber, and a water inlet pipe connected to the interior of the mixing chamber is provided on the mixing box 1. Two symmetrically arranged liquid medicine tanks 12 are fixedly provided on the top of the mixing box 1, and the liquid medicine tanks 12 are connected to the interior of the mixing chamber through a connecting pipe 13. The interiors of the two liquid medicine tanks 12 are respectively filled with chlorine dioxide solution and activator solution, which are convenient for disinfecting the water in the mixing chamber. A water storage barrel 15 connected to the interior of the mixing box 1 is provided at the bottom of the mixing box 1 for storing the disinfected water. The mixing box 1 is connected to the interior of the water storage barrel 15 through a delivery pipe 17, and a control valve 16 is provided on the delivery pipe 17. A water outlet pipe 18 connected to the interior of the water storage barrel 15 is provided at the bottom of the water storage barrel 15.
[0019] The mixing chamber is equipped with an inner mixing drum 4 and an outer mixing drum 11. The outer mixing drum 11 is sleeved over the inner mixing drum 4. The bottoms of both the inner mixing drum 4 and the outer mixing drum 11 are open to facilitate water ingress. Multiple groups of stirring rods 5 are evenly distributed around the outer circumference of the inner mixing drum 4 and the outer mixing drum 11. The multiple groups of stirring rods 5 are arranged in a circumferential array, with the multiple stirring rods 5 in each group arranged vertically at equal distances.
[0020] The mixing box 1 is provided with a drive assembly that simultaneously drives the inner mixing drum 4 and the outer mixing drum 11 to rotate in opposite directions. The drive assembly includes a motor 2, which is fixedly arranged in the middle of the top of the mixing box 1. The output end of the motor 2 extends into the mounting cavity and is fixedly provided with a connecting rod 3. The bottom end of the connecting rod 3 extends into the mixing cavity and is fixedly connected to the inner mixing drum 4. A sleeve 10 is rotatably provided in the mounting cavity. The sleeve 10 is sleeved on the outside of the connecting rod 3. The bottom end of the sleeve 10 extends into the mixing cavity and is fixedly connected to the outer mixing drum 11. A first bevel gear 7 is fixedly provided on the connecting rod 3, a third bevel gear 9 is fixedly provided on the sleeve 10, and a second bevel gear 8 is rotatably provided in the mounting cavity. The second bevel gear 8 is meshed with the first bevel gear 7 and the third bevel gear 9, respectively.
[0021] A baffle 14 is fixedly mounted on the sleeve 10 and positioned within the stirring chamber. When the baffle 14 rotates, it cooperates with the connecting tube 13 to intermittently flow liquid medicine into the stirring chamber. The baffle 14 cooperates with the connecting tube 13 to block it. The baffle 14 is symmetrically provided with notches that cooperate with the connecting tube 13 to allow the liquid medicine to flow into the stirring chamber. Therefore, when the baffle 14 rotates, it intermittently blocks and opens the connecting tube 13, allowing the liquid medicine to intermittently flow into the stirring chamber, facilitating sufficient mixing of the liquid medicine with water.
[0022] Multiple groups of through holes 6 are evenly distributed on the inner mixing drum 4 and the outer mixing drum 11. These groups of through holes 6 are arranged in a circumferential array and staggered with the corresponding groups of stirring rods 5. The multiple through holes 6 in each group are vertically equidistant. This facilitates water diversion and allows for thorough mixing of the liquid medicine and water.
[0023] The working principle of the urban area constant pressure water supply device provided by the utility model is as follows:
[0024] First, water is injected into the stirring chamber in the mixing box 1 through the inlet pipe. When the water in the mixing box 1 needs to be disinfected, the motor 2 is started, and the motor 2 drives the connecting rod 3 to rotate, the connecting rod 3 drives the first bevel gear 7 to rotate, the first bevel gear 7 drives the second bevel gear 8 to rotate, the second bevel gear 8 drives the third bevel gear 9 to rotate, the third bevel gear 9 drives the sleeve 10 to rotate, the sleeve 10 drives the baffle 14 to rotate, and the baffle 14 cooperates with the connecting pipe 13 to allow the liquid medicine to intermittently flow into the stirring chamber.
[0025] The connecting rod 3 also drives the inner mixing drum 4 to rotate, and the inner mixing drum 4 drives the stirring rod 5 on its outer surface to rotate, stirring the liquid medicine and water. The sleeve 10 drives the outer mixing drum 11 to rotate. Since the sleeve 10 rotates in the opposite direction to the connecting rod 3, the outer mixing drum 11 rotates in the opposite direction to the inner mixing drum 4. The stirring rod 5 on the outer surface of the outer mixing drum 11 also rotates in the opposite direction to the stirring rod 5 on the outer surface of the inner mixing drum 4. In addition, with the help of the through holes 6 set on the surfaces of the inner mixing drum 4 and the outer mixing drum 11, the water and liquid medicine are separated through the through holes 6 when being stirred, thereby expanding the stirring range and accelerating the mixing between the liquid medicine and water.
[0026] After stirring, the control valve 16 is opened, and the stirred water enters the water storage tank 15 through the delivery pipe 17, and then is supplied to residents through the water outlet pipe 18.
[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
